+## Version 2.10 - 'Cowbell'
+*Friday 15th April, 2016*
+[(view commits)](https://github.com/samaaron/sonic-pi/commits/v2.10.0)
+
+_"I gotta have more cowbell!"_ - The Bruce Dickinson
+
+The main feature in this release is the completely new sample system for
+working with large folders of samples. You can now easily index into and
+filter over whole folders of samples with a simple yet powerful filter
+system. This system has been in development for over a year now and has
+been tuned and tweaked over many performances and practice sessions. See
+the documentation and examples for `sample` as well as the new tutorial
+section 3.7 for details.
+
+We also have a number of exciting new sounds to play with including some
+beautifully sounding chiptune synths, fun retro FX and new drum samples
+including a full tabla set and a cowbell.
+
+Finally, even more boot issues on both OS X and Windows that have been
+fixed making this the most polished and stable release to date.
+
+Now go and get your live code on!
+
+
+### Breaking Changes
+
+* `use_sample_pack_as` and `with_sample_pack_as` have been removed.
+* A synth opt value of `nil` now no longer resolves to 0.0. Instead it
+  masks any defaults and ensures the downstream default (for the actual
+  synthdef itself) is honoured. This allows you to override any existing
+  synth defaults specified via `use_synth_defaults` for a given synth
+  trigger.
+* Default schedule ahead time is now 0.5s on all platforms for
+  consistency (except for Raspberry Pi 1 which remains at 1s).
+
+
+### New Fns
+
+* `current_random_seed` - Get the current seed value of the random generator.
+* `set_cent_tuning!` - global tuning.
+* `on` - similar to `if` but behaves the same as the `on:` opt for
+  synths and samples.
+* `halves` - create a ring of successive halves.
+* `doubles` - create a ring of successive doubles.
+* `pick` - similar to shuffle but allows duplicates. You may also
+  specify how many items to pick.
+* `fx_names` - create a ring of all available FX.
+
+### Synths & FX
+
+* New synth `:dtri` - detuned triangle waves.
+* New synth `:pluck` - a lovely synthesised plucked string.
+* New synth `:chiplead` - retro NES style lead synth.
+* New synth `:chipbass` - retro NES style bass synth.
+* New synth `:chipnoise` - retro NES style noise synth.
+* New FX `:whammy` - low-tech transposition effect similar to the
+  Digitech Whammy guitar pedal.
+* New FX `:octaver` - low-tech octave effect similar to early guitar
+  pedals.
+* New FX `:vowel` - modifies incoming signal to match human vowel
+  sounds.
+* New FX `:mono` - mono effect for summing stereo channels.
+* `:tanh` FX is now more crunchy by default.
+* `:compressor` and `:krush` FX now correctly honour the `mix:` opt.
+
+
+### Samples
+
+* Samples in FLAC format (Free Lossless Audio Codec) are now supported!
+* The `sample` fn gained source and filter pre-opts. You may now specify
+  a number of parameters directly before the opts which describe both
+  folders containing samples and filters over those folders to allow you
+  to easily and quickly work with large sample sets. See Section 3.7 of
+  the tutorial for more information.
+* Samplers now have `hpf:` and `lpf:` opts. Any `cutoff:` opts are
+  automatically switched to `lpf:` and any errors will be reported with
+  an `lpf:` prefix.
+* The sampler synth gained a compressor enabled via the `compress:`
+  opt. This means you can now compress any triggered sample directly
+  without the need to reach for an FX.
+* Samplers gained the `pre_amp:` opt which applies the amp at the
+  beginning of its internal signal chain. You can use this to overload
+  the new compressor.
+* Samplers now have both high pass and low pass filter envelopes which
+  behave similarly to the amplitude envelope but control internal hpf
+  and lpf FX. These are available via new opts which mirror the standard
+  envelope opts but with a `hpf_` and `lpf_` prefix (such as
+  `hpf_attack`, `lpf_decay_level` and friends).
+* Passing a directory path to `load_samples` will now load all the
+  samples within that directory.
+* Passing a directory path to `free_samples` will now free all the
+  loaded samples within that directory.
+* Samples are now loaded asynchronously in a separate thread. This
+  therefore doesn't block the current thread and cause any subsequent
+  synth/sample triggers to be late.
+* Sample trigger logging now includes the directory of the contained
+  sample.
+* Samples are now reloaded asynchronously after a server reboot (and
+  therefore no longer block execution).
+* Add new `:tabla_` sample group with a range of tabla drum sounds.
+* Add new `:vinyl_` sample group with a range of vinyl scratches and
+  hisses.
+* Add new samples: `:drum_cowbell`, `:drum_roll`, `:misc_cros`,
+  `:misc_cineboom`, `:perc_swash`, `:perc_till`, `:loop_safari`,
+  `:loop_tabla`.
+
+### GUI
+
+* Add new preference to enforce strict synth/FX timing. When enabled
+  synths and samples no longer trigger if it is too late - instead they
+  are silent and print a warning message. This behaviour ensures samples
+  or synths are never triggered out of time.
+* New load button which will load the contents of a file into the
+  current buffer.
+* The vertical bars which help visualise nesting now render in a
+  contiguous fashion over blank lines.
+* `C-k` now nukes over trailing whitespace.
+* `load_sample` now has sample autocompletion.
+* GUI now correctly reports if the host is a Raspberry Pi 3.
+* New editor preference - Log Auto Scroll. When enabled will always
+  scroll log to the bottom after printing every new message.
+* Whitespace at top and bottom of buffer is no longer trimmed.
+* Hitting `RETURN` now auto-indents the buffer - ensuring that the
+  cursor is moved to the correct indentation on the following line.
+* Added Chinese Simplified GUI translation.
+* Log visibility now correctly matches GUI preference.
+
+
+### Documentation
+
+* New tutorial section 3.7 on Sample Pack Filters.
+* New appendix sections.
+* Examples for `sample` fn have been completely rewritten and extended.
+
+
+### Improvements
+
+* `scale` and `chord` can now handle being passed no tonic such as:
+  `(chord :minor)` which will return a ring of offsets from 0.
+* `chord` learned new variants: `add2`, `add4`, `add9`, `add11`,
+  `add13`, `madd2`, `madd4`, `madd9`, `madd11`, `madd13`
+* The ring's `.take` method can now take more elements than the original
+  ring by wrapping around: 
+  `(ring 1, 2, 3).take(5) #=> (ring 1, 2, 3, 1, 2)`
+* Rings may now be added or subtracted from each other e.g. 
+  `(ring 1, 2,  3) + (ring 4) #=> (ring 1, 2, 3, 4)`
+* Adding or subtracting a number from a ring will create a new ring with
+  the number added or subtracted from each of the original ring's
+  elements: `(ring 1, 2, 3) - 1 #=> (ring 0.0, 1.0, 2.0)`
+* Calling `(ring 1, 2, 3).take(0)` will now return an empty ring.
+* `density` now complains if it isn't passed a do/end block.
+* Improve error messages for `use/with_synth` when accidentally passed opts.
+
+
+
+### Bugfixes
+
+* On OS X only raise an error on boot if it's clear the sound card's in
+  and out rates are different.
+* Improve robustness of boot process on Windows.
+* Rest notes are no longer printed if synth logging is disabled.
+* No longer apply synth defaults to FX.
+* You may now control opts that have no associated info (previously it
+  would raise a 'not modulatable' error).
+* Fix index lookup of Vectors.
+* Fix `C-i` doc lookup shortcut to work with `:tb303` synth docs.
+* `C-i` now always displays docs where available (previously it was
+  possible for docs not to be displayed).
+* Sliding between chords now works correctly  
+* Windows version will now boot mutiple networked machines logged in
+  with the same account.

+- Get us in touch with blind or visually impaired users
+
+  We think that Sonic Pi would be a pretty awesome tool for blind or
+  visually impaired users wanting to learn programming. If you can
+  help us get in touch with one of these users or are one of them,
+  please let us know. We don't know if the Sonic Pi GUI is useful
+  and accessible enough for you, so we don't know where to improve it
+  for your needs. Your input is highly appreciated.

 - Save/Load function for buffers
   
   Sonic Pi can save to a file, but it still doesn't have a user-friendly
   way to load existing code.
 
-- Packaging for Linux
-
-  Currently, there are binaries available for OS X, Windows and
-  Raspberry Pi Raspbian. For other Linux distributions, users have to
-  build it on their own. We'd love to find Linux enthusiasts who'd
-  volunteer to maintain packaging for their Linux distros.
-
-- Translation Server Integration
-
-  Sonic Pi translation has been a good start, but it's now turning into
-  a hassle to keep up with the changes. A translation service such as
-  Transifex etc. would be beneficial. The difficult part is how to
-  integrate this with GitHub.
-

+## Generic Linux
+
+### Dependencies
+
+Debian package dependency names (Jessie):
+
+`apt-get install supercollider ruby2.1 libqscintilla2-dev ruby-dev cmake pkg-config g++ libfftw3-dev`
+
+For Ubuntu 14.04.3 (Trusty Tahr):
+`apt-get install supercollider ruby2.0 libqscintilla2-dev ruby-dev cmake pkg-config g++ libfftw3-dev`
+
+In addition, under Ubuntu 14.04 based distributions try these:
+
+* `libqscintilla2-l10n`
+* `qt4-qmake`
+* `libqt4-dev`
+* `libffi-dev`
+
+If you are using a newer version of QT, you need the according version of scintilla. For QT5 they are:
+
+* `libqt5scintilla2-dev` instead of `libqscintilla2-dev`
+* `libqt5scintilla2-l10n` instead of `libqscintilla2-l10n`
+
+Fedora package dependency names:
+
+* `supercollider` (via [Planet CCRMA](http://ccrma.stanford.edu/planetccrma/software/installplanettwenty.html))
+* `ruby` (or use [RVM](http://rvm.io/) to manage specific versions)
+* `qscintilla-devel` (will install `qscintilla` and `qt-devel`)
+* `cmake`
+
+### SuperCollider SC3 Plugins
+
+After installing SuperCollider, you will also need to compile and
+install the [SuperCollider SC3 UGen Plugins](https://github.com/supercollider/sc3-plugins)
+from source, if your distribution does not provide a binary package of them.
+
+You will need your distribution's `supercollider-dev` package for this step.
+
+```
+git clone https://github.com/supercollider/sc3-plugins.git
+cd sc3-plugins
+git submodule init
+git submodule update
+git checkout efba3baaea873f4e4d44aec3bb7468dd0938b4a6
+cp -r external_libraries/nova-simd/* source/VBAPUGens
+mkdir build
+cd build
+cmake -DSC_PATH=/usr/include/SuperCollider -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release ..
+make
+sudo make install
+```
+
+### Server extensions
+
+Compile the server extensions by `cd`ing into the directory `app/server/bin` and running the script `compile-extensions.rb`. This will take some time.
+
+### Qt GUI
+
+You must compile the server extensions prior to this step.
+
+`cd` into the directory `app/gui/qt/` and run the script `rp-build-app`. This will also take some time.
+
+### Running
+
+Start the jack sound server daemon `jackd`. This is easily done through [qjackctl](http://qjackctl.sourceforge.net/), available as `qjackctl` in Debian.
+
+that didn't work for me, but typing this, after randomly googling and trying various things, did:
+`jackd -R -d alsa -d hw:1`
+
+On systems like Ubuntu that run pulseaudio, use
+`pasuspender -- jackd -R -d alsa`
+
+Then run the script `sonic-pi` in the directory `app/gui/qt`.
+
+----
+
+## Arch Linux
+
+### AUR Package
+
+Arch Linux users are strongly recommended to install the [sonic-pi-git](https://aur.archlinux.org/packages/sonic-pi-git/) package from the AUR; see the wiki article on the [Arch User Repository](https://wiki.archlinux.org/index.php/Arch_User_Repository) if you are unfamiliar with how to install such a package. The PKGBUILD found in this package will:
+* Clone the latest sonic-pi source from GitHub
+* Apply a patch to fix a library naming issue
+* Build sonic-pi from source, according to the instructions found in [Generic Linux](#generic-linux)
+* Install the built software components to `/opt/sonic-pi-git`
+* Install the launcher to `/usr/bin/sonic-pi`
+
+After installing, users need to follow the instructions in the [Generic Linux](#generic-linux) section to start the `jackd` server, and then run `sonic-pi` at a command prompt.
+
+### Building from source
+
+Users can opt to build from source as well if they would like. Instructions and dependencies can be found within the PKGBUILD file in the AUR package previously mentioned, as well as the required patch file.
+
+----
+
+## Linux Mint (beta)
+
+### PPA
+
+Tested on Linux Mint 17.2, inspired by [this issue](https://github.com/samaaron/sonic-pi/issues/827).
+
+First, install the binary:
+
+```
+sudo add-apt-repository ppa:sonic-pi/ppa
+sudo apt-get update
+sudo apt-get install sonic-pi
+```
+
+Next, install qjackctl:
+
+`sudo apt-get install qjackctl`
+
+Then, launch qjackctl from the command line (while suspending PulseAudio):
+
+`pasuspender -- qjackctl`
+
+Click the 'Start' button in qjackctl, then launch Sonic Pi :)

+# Mac OS X
+
+## Dependencies
+
+* Download Qt 5.4+ http://qt-project.org/downloads
+* Run the setup wizard and install to a known location which we'll call `/path/to/qt`
+* Grab a copy of the QScintilla libs http://www.riverbankcomputing.co.uk/software/qscintilla/download and untar into a known location which we'll call `/path/to/qscintilla`
+  (current version is QScintilla-gpl-2.9)
+* Install SuperCollider 3.6 from http://supercollider.github.io/download.html
+* Download SuperCollider extensions from http://sourceforge.net/projects/sc3-plugins/files/OSX_3.6/SC3ExtPlugins-universal.dmg/download and install as per the included README.txt file
+* Grab a copy of Sonic Pi's source to a known location (which we'll call `/path/to/sonic-pi/root/`)
+  - `cd /path/to/sonic-pi/root/`
+  - `git clone git://github.com/samaaron/sonic-pi.git`
+
+
+## Create Symlinks for Ruby and SuperCollider's scsynth
+
+* Provide a Ruby version for Sonic Pi to use
+  - The Qt app expects Ruby to exist at a certain path. We can use a symlink to provide an appropriate Ruby Version
+  - `cd /path/to/sonic-pi/root/`
+  - `mkdir -p app/server/native/osx/ruby/bin`
+  - link the ruby version into place:
+  - ``ln -s `which ruby` app/server/native/osx/ruby/bin/ruby``
+* Provide a SuperCollider scsynth for Sonic Pi to use  
+ - The Qt app expects scsynth to exist at a certain path. We can also use a symlink here.
+ - `cd /path/to/sonic-pi/root/`
+ - `cd app/server/native/osx/`
+ - `ln -s /Applications/SuperCollider/SuperCollider.app/Contents/Resources/scsynth .`
+
+## Compile Ruby Server extensions
+### Prerequisites
+In order to compile the ruby libraries successfully, make sure you have
+the following programs installed:
+
+* [cmake](https://cmake.org)
+* [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/)
+
+If you want to check whether you have them installed already, you can do
+so by typing the following commands in your terminal:
+
+* `cmake` - If installed, it will show the usage of the program
+* `pkg-config` - If installed, it will show a message indicating that a 
+package name should be specified.
+
+Installation of both the programs can be done through Homebrew or MacPorts
+
+### Compiling
+Sonic Pi uses some ruby libraries which have native extensions. We need
+to compile these with the provided script:
+
+* `cd /path/to/sonic-pi/root/`
+* `cd app/server/bin`
+* `../native/osx/ruby/bin/ruby compile-extensions.rb`
+
+This will take some time. Ignore the warnings.
+
+## Qt GUI
+
+### Xcode 6 and lower
+
+* Build QScintilla:
+  - `cd /path/to/qscintilla/Qt4Qt5`
+  - generate makefile: `/path/to/qt/5.4/clang_64/bin/qmake qscintilla.pro`
+  - `make`
+* Add the following to SonicPi.pro:
+```
+    LIBS += -L /path/to/qscintilla/Qt4Qt5/ -lqscintilla2
+    INCLUDEPATH += /path/to/qscintilla/Qt4Qt5/
+    DEPENDPATH += /path/to/qscintilla/Qt4Qt5/
+```
+* Modify top of mac-build-app appropriately i.e.
+```
+    QSCINTILLA=/path/to/qscintilla/Qt4Qt5
+    QTBIN=/path/to/qt/5.4/clang_64/bin    
+```
+### Xcode 7+
+
+* Build QScintilla:
+  - `cd /path/to/qscintilla/Qt4Qt5`
+  - Add the following to `qscintilla.pro`
+      QMAKE_MAC_SDK = macosx10.11
+  - generate makefile: `/path/to/qt/5.4/clang_64/bin/qmake qscintilla.pro`
+  - `make`
+  - update the dylib inner path part 1: `install_name_tool -id "/path/to/qscintilla/Qt4Qt5/libqscintilla2.12.dylib" /path/to/qscintilla/Qt4Qt5/libqscintilla2.12.dylib`
+  - update the dylib inner path part 2: `install_name_tool -change "libqscintilla2.12.dylib" "/path/to/qscintilla/Qt4Qt5/libqscintilla2.12.dylib" /path/to/qscintilla/Qt4Qt5/libqscintilla2.12.dylib` 
+* Add the following to SonicPi.pro
+```
+    LIBS += -L /path/to/qscintilla/Qt4Qt5/ -lqscintilla2
+    INCLUDEPATH += /path/to/qscintilla/Qt4Qt5/
+    DEPENDPATH += /path/to/qscintilla/Qt4Qt5/
+```    
+* Add the following to SonicPi.pro
+```
+    QMAKE_MAC_SDK = macosx10.11
+```    
+* Modify top of mac-build-app appropriately i.e.
+```    
+    QSCINTILLA=/path/to/qscintilla/Qt4Qt5
+    QTBIN=/path/to/qt/5.4/clang_64/bin
+```    
+
+
+## Building the App
+
+Finally, we need to build the OS X App
+
+* `cd /path/to/sonic-pi/root/`
+* `cd app/gui/qt`
+* `./mac-build-app`
+* App should be in `build` dir which you can either launch via Finder or via the following from the `qt` dir:
+* `./build/Sonic\ Pi.app/Contents/MacOS/Sonic\ Pi`
+
+Sonic Pi should now boot successfully.

+# SONIC PI DETAILED BUILD YOUR OWN INSTRUCTIONS FOR WINDOWS 10 BASED ON LATEST SP 2.9dev after e7fde3a
+
+Last revision 29th December 2015 @ 7:32PM AWST   (minor grammar improvement)
+
+Tested on Windows 10 64bit (running under vmware fusion on a Mac) and Windows 7 64bit.
+
+This document details the process from beginning to end to build Sonic Pi 2.9dev and I hope it will be useful to others, and encourage them to have a go themselves.
+
+First there is quite a bit of software to install to facilitate the build, not least the source files for Sonic Pi.
+
+First install **git** from https://msysgit.github.io/ click **download** then run `Git-2.6.3-64-bit.exe` I selected options **Use git from Windows Command Prompt**, **Checkout Windows-style**, **commit Unix-style line endings**, **Use Windows default console window**, and **Enable file system caching**
+
+Now install the **Sonic Pi source files**. I put mine at the top level of the c: drive
+Start a command window by typing **cmd** in the search field
+```
+cd c:/
+git clone https://github.com/samaaron/sonic-pi.git
+```
+
+Now download **Visual Studio Express 2013 for Windows Desktop with Update 5** from
+https://www.visualstudio.com/downloads/download-visual-studio-vs
+scroll down the page and find **Visual Studio 2013**, and then **Express 2013 for Desktop**.
+You can either choose **Web Installer** or **ISO** depending upon whether you want to install over the web or download a complete 3.3Gb and install from that. I did the full download, mounted the iso disk image and installed from that.
+
+Download **Qt**. use **version 5.5.1** as version 5.4.x is NOT qualified for Windows 10
+I went to http://www.qt.io/download-open-source/#section-2
+And selected **Qt 5.5.1 for Windows 32-bit (VS 2013, 804 MB)** 
+
+http://download.qt.io/official_releases/qt/5.5/5.5.1/qt-opensource-windows-x86-msvc2013-5.5.1.exe
+After download, I ran the installer, accepting the default settings, which installs Qt at
+```C:\Qt\Qt5.5.1``` (I skipped setting up an account!)
+
+Install **cmake** from the link http://www.cmake.org/download
+Scroll down and select ```cmake-3.4.1-win32-x86.exe``` and download.
+Run the installer, selecting the option **Add to the System PATH for all (or current) users**
+
+
+Install **Ruby** from http://rubyinstaller.org/downloads/
+I choose **Ruby 2.2.3** although the install works with 2.1.7 with minor alterations which are detailed below.
+Choose the **32 bit version**
+Run the installer when downloaded. Choose the default install ```c:\Ruby22``` (C:\Ruby21 if you use Ruby2.1.7)
+Select **add Ruby Executables to your path** and **associate .rb and .rbw files with this installation**.
+
+Scroll further down the page of http://rubyinstaller.org/downloads/ and select
+```DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe``` and download that as well
+Make sure you use the **32 bit version for Ruby 2.0 and higher**.
+When downloaded, run this and set the extract location to ```c:\RubyDev```
+
+Now you have to complete the installation as follows:
+In a command window
+```
+cd c:\RubyDev
+ruby dk.rb init
+```
+
+This will create a file ```config.yml``` inside the ```RubyDev``` folder
+Check its contents by typing;
+```Notepad config.yml```
+You should see a line ``` - C:\Ruby22```
+at the end of the file. ( - C:\Ruby21 if you use Ruby2.1.7)
+Close notepad
+Now type
+```ruby dk.rb install```
+
+Now you add two files from **pkgconfiglite**
+Open the link
+http://sourceforge.net/projects/pkgconfiglite/files
+and select
+**Looking for the latest version? Download pkg-config-lite-0.28-1_bin-win32.zip (47.7 kB)**
+When the file has downloaded, extract and then copy the file ```pkg-config``` from the ```bin``` folder to ```c:\RubyDev\bin```
+and the file ```pkg.m4``` from the ```share\aclocal``` folder to ```c:\RubyDev\share\aclocal```
+
+That completes the setup for RubyDev
+
+### Preparing the Ruby section
+This section of the Sonic Pi install.md file should be completed next BEFORE attempting the section **Qt GUI** (unlike in the original install.md document) as the final build in this section requires one of the gems to be installed before it is run.
+
+Copy ```c:\ruby22\*``` into ```c:\sonic-pi\apps\server\native\windows\ruby```
+(amend to c:\Ruby21\* if you use Ruby2.1.7)
+You will need to create the last two folders windows\ruby before doing this, which is best done from a File Explorer window. The copying is also best done using **two** File Explorer windows, one set to ```c:\Ruby22``` (or C:Ruby21  if you use Ruby2.1.7) and the other to ```c:\sonic-pi\app\server\native\windows\ruby```
+You can leave out the **Doc** folder and the two **unins000** files.
+Now open a cmd window and navigate to c:\sonic-pi\app\server\native\windows\ruby
+From there we will install gem files required by Sonic Pi
+
+```.\bin\gem install did_you_mean```
+
+(allow access if you are asked). The install may take a little time. Eventually it will say two gems installed (did_you_mean and interception)
+
+```.\bin\gem install ffi```
+
+
+Another gem recently added, that is needed specifically for the windows install is ```win32-process```
+
+```.\bin\gem install win32-process```
+
+The fourth gem file is problematical, and needs a patch to install. It goes like this:
+
+```.\bin\gem fetch rugged```
+
+This will fetch the latest version which is rugged-0.23.3
+
+```
+.\bin\gem unpack rugged-0.23.3.gem
+.\bin\gem spec rugged-0.23.3.gem --ruby > rugged-0.23.3\rugged.gemspec
+```
+
+Now we have to apply a patch to one of the files.
+
+```
+cd rugged-0.23.3\ext\rugged
+notepad extconf.rb
+```
+In the notepad window select **Find** from the Edit Menu (**ctrl+F**) and search for
+
+```Unix Makefiles\””)```
+
+and change it to read
+
+```Unix Makefiles\" -DCMAKE_INSTALL_PREFIX=C:/ -DWINHTTP=OFF")```
+
+NB: this may no longer be needed with current versions of rugged
+
+Then resave the file and quit notepad.
+Go back to the cmd window
+
+```cd ..\..\```
+ 
+you should be back in the folder ```c:\sonic-pi\app\server\native\windows\ruby\rugged-0.23.3```
+
+Now build the patched rugged
+
+```
+..\bin\gem build rugged.gemspec
+..\bin\gem install rugged-0.23.3.gem
+```
+
+NB: rb-native is not being used for Windows packages, the gems can happily live where they were installed by the "local" Ruby.  You MAY need to delete the vendor/rugged directory so it uses the right version.
+
+That completes the ruby preparation work. Close the cmd and FileExplorer windows.
+
+
+### Preparing the Qt GUI
+From the **Start Button** select **All apps** and scroll down to **Visual Studio 2013**, and then to **Visual Studio Tools**. From the Window that opens **right click**  **VS2013 x86 Native Tools Command Prompt** and **Pin it to the Taskbar**. **Double click it** there to open a window which should be titled **VS2013 x86 Native Tools Command Prompt**.
+
+Type **path** in that window after the prompt and press the enter key.
+
+You will see a long string of folder locations which comprise the path associated with the window, which it will automatically search. It includes links to the various elements of visual studio. However, we have to add one more item, which is the path of the Qt bin directory.
+
+Since the Visual Studio prompt path is rebuilt each time a window is opened, I have found the convenient way to do this is to create a **batch file** which can be run each time to add the additional entry. Since I want to store this at the C:\ top level, we have to run the cmd window with administrative privileges to create it.
+Close the open Visual Studio Command Prompt window, then reopen it, holding down **Shift** and **Ctrl** when you do so. Say **Yes** to the popup window, and you will then have a cmd window with admin privileges. 
+
+```
+cd c:\
+notepad
+```
+
+In the open notepad window type
+```
+PATH=%PATH%;C:\Qt\Qt5.5.1\5.5\msvc2013\bin
+```
+
+Then select **save** and save the file as ```pathupdate.bat```, at the top level of ```c:\``` Make sure you select **All Files** for the type so the extension can be set to **.bat** and NOT **.txt**
+
+Close notepad and type ```dir``` (and press return) You should see the file ```pathupdate.bat``` listed.
+
+Close the cmd window and double click the icon on the taskbar to reopen it with "normal" privileges.
+
+```
+cd c:\
+pathupdate.bat
+```
+
+You should see the long path as before, but now with an additional entry ```C:\Qt\Qt5.5.1\5.5\msvc2013\bin``` at the end
+Leave this window open.
+
+Download **Qscintilla** from https://www.riverbankcomputing.com/software/qscintilla/download
+
+Select the ```Qscintilla-gpl-2.9.1.zip``` file to download
+When downloaded extract the ```Qscintilla-gpl-2.9.1``` folder to ```c:\```
+
+Return to the visual studio command window. 
+```
+cd c:\QScintilla-gpl-2.9.1\Qt4Qt5
+qmake qscintilla.pro
+nmake
+```
+(it will now be compiled)
+```
+nmake install
+```
+keep the cmd window open
+
+copy ```Qt4Qt5\release\moc_qsciscintilla.cpp``` and ```moc_qsciscintillabase.cpp``` to 
+```c:\sonic-pi\app\gui\qt\platform\win``` (There may be two files there already, but overwrite them)
+Best done using two FileExplorer windows as before.
+
+Now we do the main build of Sonic-Pi gui, using the open cmd window.
+```
+cd c:\sonic-pi
+.\app\gui\qt\win-build-app.bat
+```
+This should carry out the build. Don’t worry about various warnings en route.
+We now add some files from visual studio which will be needed at run time.
+Open two FileExplorer windows. In the first navigate to:
+
+```Local Disk (C:)> Program Files (x86) > Microsoft Visual Studio 12.0 > VC > redist > x86 > Microsoft.VC120.CRT```
+
+In the second to
+
+```Local Disk (C:)> sonic-pi> app > gui > qt > release```
+
+Copy msvcp120.dll and msvcr120.dll from the former to the latter.
+
+In the second window navigate to **sonic-pi.exe** and **right-click** it to create a shortcut. Drag the shortcut to the desktop. Do NOT attempt to run it yet.
+
+###  The final stage deals with SuperCollider
+Install SuperCollider from http://supercollider.github.io/download.html
+Select the **Win32 3.6.6** installer and download it
+
+Run the installer
+
+Download additional SuperCollider plugins from
+
+http://sourceforge.net/projects/sc3-plugins/files/sc3-plugins%20Windows/
+
+Select the latest version link at the top of the page and download
+```Looking for the latest version? Download sc3-plugins-3.6.0-win32.zip (10.3 MB)```
+Extract them in the download folder.
+
+NB: The current Sonic Pi 2.9 is packaged with sc3-plugins 3.7.0-beta (f978dc2), which can be compiled in an MSYS environment as follows:
+* install FFTW3 binaries from ftp://ftp.fftw.org/pub/fftw/fftw-3.3.4-dll32.zip to `/home/sc/fftw3.3.4-dll32` for example
+* `git clone https://github.com/supercollider/sc3-plugins.git`
+* `cd sc3-plugins && git submodule init && git submodule update`
+* `mkdir build && cd build`
+* `cmake -DSC_PATH=/home/sc/sources/supercollider/ -DFFTW3F_LIBRARY=/home/sc/fft w-3.3.4-dll32/libfftw3f-3.dll -DFFTW3F_INCLUDE_DIR=/home/sc/fftw3.3.4-dll32 -G "Unix Makefiles" ..`
+* manually add `-IC:/msys/home/sc/fftw-3.3.4-dll32/` to `build/source/CMakeFiles/PitchDetection.dir/includes_CXX.rsp` (no idea why)
+* make install
+* copy SCX files from `c:\program files (x86)\sc3-plugins` or wherever it installs them
+
+We now copy files to the sonic-pi installation.
+
+With two FileExplorer windows navigate the first to ```Local Disk (C:) >Program Files (x86) > SuperCollider```
+
+And the second (destination) to ```Local Disk (C:)> sonic-pi > app > server > native > windows```
+
+Copy the ```plugins``` folder from the former to the latter.
+
+Copy all dll files **EXCEPT those starting with QT** from the former to the latter.
+
+Copy ```scsynth.exe``` from the former to the latter.
+
+Keep these windows open for the moment.
+
+Open the ```sc3-plugins-3.6.0-win32``` folder in the Downloads folder and navigate to ```SC3-plugins```.
+Copy all the *.scx files that folder into the ```plugins``` folder copied to destination folder in the previous step.
+
+Close the open FileExplorer windows.
+
+There is one final patch to install. The Ugen file associated with the Piano synth was updated in the summer, to eliminate a problem with the tuning. Unfortunately the current Ugen has NOT yet been updated for windows, and consequently we have to use a modified version of the MdaUgen. This can be downloaded from https://goo.gl/K316fw
+Extract the contents and follow the instructions in the readme file. Basically you replace the file ```sonic-pi-piano.scsyndef``` in ```c:\sonic-pi\etc\synthdefs\compiled``` with the one downloaded in the patch.
+
+(You may like to retain a copy of the original before overwriting it, or perhaps rename it to ```sonic-pi-piano.scsyndef.original```)
+
+### Finished!
+That should complete the installation of Sonic Pi.
+Try running it by double clicking the Sonic Pi shortcut on the desktop.

 # Installing Sonic Pi from Source
 
 If you want to use the very latest development version of Sonic Pi, then
-you'll need to compile from source. Here are instructions for the
-following platforms:
-
-* [Raspberry Pi](#raspberry-pi)
-* [Generic Linux](#generic-linux)
-* [Arch Linux](#arch-linux)
-* [Mac OS X](#mac-os-x)
-* [Windows](#windows)
-
-----
-
-## Raspberry Pi
-
-The Raspberry Pi will happily compile all the required aspects of Sonic
-Pi. However, be warned that it will take quite some time to complete.
-
-First grab the dependencies, compile the server extensions, then the GUI then start the app.
-
-### Dependencies
-
-The dependencies for building and running this are:
-
-* `supercollider`
-* `ruby1.9.3`
-* `libqscintilla2-8`
-* `libqscintilla2-dev`
-* `qt4-dev-tools`
-* `cmake`
-* `ruby-dev`
-* `libffi-dev`
-
-Use `sudo apt-get install` to ensure each of these are on your system.
-
-### Server extensions
-
-Compile the server extensions by `cd`ing into the directory `app/server/bin` and running the script `compile-extensions.rb`. This will take some time.
-
-### Qt GUI
-
-`cd` into the directory `app/gui/qt/` and run the script `rp-build-app`. This will also take some time.
-
-### Running
-
-Run the script `rp-app-bin` in the directory `app/gui/qt`.
-
------
-
-## Generic Linux
-
-### Dependencies
-
-Debian package dependency names (Jessie):
-
-`apt-get install supercollider ruby2.1 libqscintilla2-dev ruby-dev cmake pkg-config g++`
-
-For Ubuntu 14.04.3 (Trusty Tahr):
-`apt-get install supercollider ruby2.0 libqscintilla2-dev ruby-dev cmake pkg-config g++`
-
-In addition, under Ubuntu 14.04 based distributions try these:
-
-* `libqscintilla2-l10n`
-* `qt4-qmake`
-* `libqt4-dev`
-* `libffi-dev`
-
-If you are using a newer version of QT, you need the according version of scintilla. For QT5 they are: 
-
-* `libqt5scintilla2-dev` instead of `libqscintilla2-dev`
-* `libqt5scintilla2-l10n` instead of `libqscintilla2-l10n`
-
-In addition, you need to tell sonic-pi to use these. In order to do so, navigate to `app/gui/qt/`
-and open `SonicPi.pro`with your text editor of choice.
-Replace `lqscintilla2`with `lqt5scintilla2` everywhere it is written.
-
-Fedora package dependency names:
-
-* `supercollider` (via [Planet CCRMA](http://ccrma.stanford.edu/planetccrma/software/installplanettwenty.html))
-* `ruby` (or use [RVM](http://rvm.io/) to manage specific versions)
-* `qscintilla-devel` (will install `qscintilla` and `qt-devel`)
-* `cmake`
-
-### Server extensions
-
-Compile the server extensions by `cd`ing into the directory `app/server/bin` and running the script `compile-extensions.rb`. This will take some time.
-
-### Qt GUI
-
-`cd` into the directory `app/gui/qt/` and run the script `rp-build-app`. This will also take some time.
-
-### Running
-
-Start the jack sound server daemon `jackd`. This is easily done through [qjackctl](http://qjackctl.sourceforge.net/), available as `qjackctl` in Debian.
-
-that didn't work for me, but typing this, after randomly googling and trying various things, did:
-`jackd -R -d alsa -d hw:1`
-
-On systems like Ubuntu that run pulseaudio, use
-`pasuspender -- jackd -R -d alsa` 
-
-Then run the script `sonic-pi` in the directory `app/gui/qt`.
-
-----
-
-## Arch Linux
-
-### AUR Package
-
-Arch Linux users are strongly recommended to install the [sonic-pi-git](https://aur.archlinux.org/packages/sonic-pi-git/) package from the AUR; see the wiki article on the [Arch User Repository](https://wiki.archlinux.org/index.php/Arch_User_Repository) if you are unfamiliar with how to install such a package. The PKGBUILD found in this package will:
-* Clone the latest sonic-pi source from GitHub
-* Apply a patch to fix a library naming issue
-* Build sonic-pi from source, according to the instructions found in [Generic Linux](#generic-linux)
-* Install the built software components to `/opt/sonic-pi-git`
-* Install the launcher to `/usr/bin/sonic-pi`
-
-After installing, users need to follow the instructions in the [Generic Linux](#generic-linux) section to start the `jackd` server, and then run `sonic-pi` at a command prompt. 
-
-### Building from source
-
-Users can opt to build from source as well if they would like. Instructions and dependencies can be found within the PKGBUILD file in the AUR package previously mentioned, as well as the required patch file. 
-
-----
-
-## Mac OS X
-
-### Dependencies
-
-* Download Qt 5.4+ http://qt-project.org/downloads
-* Run the setup wizard and install to a known location which we'll call /path/to/qt
-* Grab a copy of the QScintilla libs http://www.riverbankcomputing.co.uk/software/qscintilla/download and untar into a known location which we'll call /path/to/qscintilla
-  (current version is QScintilla-gpl-2.9)
-* Install SuperCollider 3.6 from http://supercollider.github.io/download.html
-* Download SuperCollider extensions from http://sourceforge.net/projects/sc3-plugins/files/OSX_3.6/ and install as per the included README.txt file
-
-### Server extensions
-
-Compile the server extensions by `cd`ing into the directory `app/server/bin` and running the script `compile-extensions.rb`. This will take some time.
-
-### Qt GUI
-
-* Build QScintilla:
-  - `cd /path/to/qscintilla/Qt4Qt5`
-  - generate makefile: `/path/to/qt/5.4/clang_64/bin/qmake qscintilla.pro`
-  - `make`
-  - (OSX only) update the dylib inner path part 1: `install_name_tool -id "/path/to/qscintilla/Qt4Qt5/libqscintilla2.12.dylib" /path/to/qscintilla/Qt4Qt5/libqscintilla2.12.dylib`
-  - (OSX only) update the dylib inner path part 2: `install_name_tool -change "libqscintilla2.12.dylib" "/path/to/qscintilla/Qt4Qt5/libqscintilla2.12.dylib" /path/to/qscintilla/Qt4Qt5/libqscintilla2.12.dylib` 
-* Add the following to SonicPi.pro
-    LIBS += -L /path/to/qscintilla/Qt4Qt5/ -lqscintilla2
-    INCLUDEPATH += /path/to/qscintilla/Qt4Qt5/
-    DEPENDPATH += /path/to/qscintilla/Qt4Qt5/
-* Modify top of mac-build-app appropriately i.e.
-    QSCINTILLA=/path/to/qscintilla/Qt4Qt5
-    QTBIN=/path/to/qt/5.4/clang_64/bin
-* Provide a Ruby version for Sonic Pi to use
-  - The Qt app expects Ruby to exist at a certain path. We can use a symlink to provide an appropriate Ruby Version
-  - `$ cd /root/path/to/sonic-pi`
-  - `$ mkdir -p app/server/native/osx/ruby/bin`
-  - check your current ruby version: 
-```
-# This should be 2.1.2 although anything 1.9.3+ _should_ work
-$ ruby --version
-```
-  - link the ruby version into place:
-```
-ln -s `which ruby` app/server/native/osx/ruby/bin/ruby
-```
-* Compile any native extensions: `$ app/server/bin/compile-extensions.rb`
-* Run `./mac-build-app`
-* App should be in `build` dir
-
-----
-
-## Windows
-
-### Building
-
-Follow the instructions in [WindowsInstall.md](WindowsInstall.md)
-
-### Packaging
-* TODO: there should be a "make distclean" target to clean up the tree for MSI packaging
-  - or else a script to build a release tree by copying things out of the working tree
-* There is a WiX project file in `sonic-pi.wxs` -- work in progress
-  - download [WiX Toolset](http://wixtoolset.org/)
-  - see comments at top of sonic-pi.wxs for packaging
+you'll need to compile from source. Due to the complex nature of Sonic
+Pi's architecture this should only be considered by those happy playing
+around with the Terminal and are happy working with bleeding edge
+software. 
+
+For all other users, downloading the latest pre-built app for your
+platform is highly recommended: http://sonic-pi.net
+ 
+
+There are instructions for the following platforms in their own separate
+files:
+
+* Raspberry Pi - `INSTALL-RASPBERRY-PI.md`
+* Windows - `INSTALL-WINDOWS.md`
+* Mac - `INSTALL-MAC.md`
+* Linux - `INSTALL-LINUX.md`

-# SONIC PI DETAILED BUILD YOUR OWN INSTRUCTIONS FOR WINDOWS 10 BASED ON LATEST SP 2.9dev after e7fde3a
-
-Last revision 29th December 2015 @ 7:32PM AWST   (minor grammar improvement)
-
-Test bed was a Windows 10 64bit install (running under vmware fusion on a Mac)
-
-This document details the process from beginning to end to build Sonic Pi 2.9dev and I hope it will be useful to others, and encourage them to have a go themselves.
-
-Prerequisite. A windows 10 computer with internet connection and working soundcard.
-
-First there is quite a bit of software to install to facilitate the build, not least the source files for Sonic Pi.
-
-First install **git** from https://msysgit.github.io/ click **download** then run `Git-2.6.3-64-bit.exe` I selected options **Use git from Windows Command Prompt**, **Checkout Windows-style**, **commit Unix-style line endings**, **Use Windows default console window**, and **Enable file system caching**
-
-Now install the **Sonic Pi source files**. I put mine at the top level of the c: drive
-Start a command window by typing **cmd** in the search field
-```
-cd c:/
-git clone https://github.com/samaaron/sonic-pi.git
-```
-
-Now download **Visual Studio Express 2013 for Windows Desktop with Update 5** from
-https://www.visualstudio.com/downloads/download-visual-studio-vs
-scroll down the page and find **Visual Studio 2013**, and then **Express 2013 for Desktop**.
-You can either choose **Web Installer** or **ISO** depending upon whether you want to install over the web or download a complete 3.3Gb and install from that. I did the full download, mounted the iso disk image and installed from that.
-
-Download **Qt**. use **version 5.5.1** as version 5.4.x is NOT qualified for Windows 10
-I went to http://www.qt.io/download-open-source/#section-2
-And selected **Qt 5.5.1 for Windows 32-bit (VS 2013, 804 MB)** 
-
-http://download.qt.io/official_releases/qt/5.5/5.5.1/qt-opensource-windows-x86-msvc2013-5.5.1.exe
-After download, I ran the installer, accepting the default settings, which installs Qt at
-```C:\Qt\Qt5.5.1``` (I skipped setting up an account!)
-
-Install **cmake** from the link http://www.cmake.org/download
-Scroll down and select ```cmake-3.4.1-win32-x86.exe``` and download.
-Run the installer, selecting the option **Add to the System PATH for all (or current) users**
-
-
-Install **Ruby** from http://rubyinstaller.org/downloads/
-I choose **Ruby 2.2.3** although the install works with 2.1.7 with minor alterations which are detailed below.
-Choose the **32 bit version**
-Run the installer when downloaded. Choose the default install ```c:\Ruby22``` (C:\Ruby21 if you use Ruby2.1.7)
-Select **add Ruby Executables to your path** and **associate .rb and .rbw files with this installation**.
-
-Scroll further down the page of http://rubyinstaller.org/downloads/ and select
-```DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe``` and download that as well
-Make sure you use the **32 bit version for Ruby 2.0 and higher**.
-When downloaded, run this and set the extract location to ```c:\RubyDev```
-
-Now you have to complete the installation as follows:
-In a command window
-```
-cd c:\RubyDev
-ruby dk.rb init
-```
-
-This will create a file ```config.yml``` inside the ```RubyDev``` folder
-Check its contents by typing;
-```Notepad config.yml```
-You should see a line ``` - C:\Ruby22```
-at the end of the file. ( - C:\Ruby21 if you use Ruby2.1.7)
-Close notepad
-Now type
-```ruby dk.rb install```
-
-Now you add two files from **pkgconfiglite**
-Open the link
-http://sourceforge.net/projects/pkgconfiglite/files
-and select
-**Looking for the latest version? Download pkg-config-lite-0.28-1_bin-win32.zip (47.7 kB)**
-When the file has downloaded, extract and then copy the file ```pkg-config``` from the ```bin``` folder to ```c:\RubyDev\bin```
-and the file ```pkg.m4``` from the ```share\aclocal``` folder to ```c:\RubyDev\share\aclocal```
-
-That completes the setup for RubyDev
-
-### Preparing the Ruby section
-This section of the Sonic Pi install.md file should be completed next BEFORE attempting the section **Qt GUI** (unlike in the original install.md document) as the final build in this section requires one of the gems to be installed before it is run.
-
-Copy ```c:\ruby22\*``` into ```c:\sonic-pi\apps\server\native\windows\ruby```
-(amend to c:\Ruby21\* if you use Ruby2.1.7)
-You will need to create the last two folders windows\ruby before doing this, which is best done from a File Explorer window. The copying is also best done using **two** File Explorer windows, one set to ```c:\Ruby22``` (or C:Ruby21  if you use Ruby2.1.7) and the other to ```c:\sonic-pi\app\server\native\windows\ruby```
-You can leave out the **Doc** folder and the two **unins000** files.
-Now open a cmd window and navigate to c:\sonic-pi\app\server\native\windows\ruby
-From there we will install gem files required by Sonic Pi
-
-```.\bin\gem install did_you_mean```
-
-(allow access if you are asked). The install may take a little time. Eventually it will say two gems installed (did_you_mean and interception)
-
-```.\bin\gem install ffi```
-
-
-Another gem recently added, that is needed specifically for the windows install is ```win32-process```
-
-```.\bin\gem install win32-process```
-
-The fourth gem file is problematical, and needs a patch to install. It goes like this:
-
-```.\bin\gem fetch rugged```
-
-This will fetch the latest version which is rugged-0.23.3
-
-```
-.\bin\gem unpack rugged-0.23.3.gem
-.\bin\gem spec rugged-0.23.3.gem --ruby > rugged-0.23.3\rugged.gemspec
-```
-
-Now we have to apply a patch to one of the files.
-
-```
-cd rugged-0.23.3\ext\rugged
-notepad extconf.rb
-```
-In the notepad window select **Find** from the Edit Menu (**ctrl+F**) and search for
-
-```Unix Makefiles\””)```
-
-and change it to read
-
-```Unix Makefiles\" -DCMAKE_INSTALL_PREFIX=C:/ -DWINHTTP=OFF")```
-
-Then resave the file and quit notepad.
-Go back to the cmd window
-
-```cd ..\..\```
- 
-you should be back in the folder ```c:\sonic-pi\app\server\native\windows\ruby\rugged-0.23.3```
-
-Now build the patched rugged
-
-```
-..\bin\gem build rugged.gemspec
-..\bin\gem install rugged-0.23.3.gem
-
-
-```
-create the directory path ```c:\sonic-pi\app\server\rb-native\windows\2.2.0```
-
-You will have to create the last two folders windows\2.2.0 in this path. Easiest to do this with  FileExplorer Window NB if you are using Ruby 2.1.x you will substitute the folder 2.1.0 instead of 2.2.0 here. The compiled shared libraries for the gems will be copied to this folder. Keep this window (hereafter referred to as the ```gem .so folder```) open for the purpose.
-
-Different versions of Ruby appear to store the compiled libraries in different places, so it is probably easiest to search for them using a new FileExplorer Window. Open such a window, and navigate to
-```
-c:\ > sonic-pi > app > server > native > windows > ruby > lib > ruby > gems
-```
-You will use this window three times to search for the three .so files which need to be copied.
-
-A) ***did_you_mean gem*** The shared object file in this case is called ```method_receiver.so``` It will be copied to a folder ```did_you_mean``` which you have to create in the ```gem .so folder``` referred to above.
-To find it, type ```method*.so``` in the search field (top right) 
-Select one of the hits, right click and select open file location. This should reveal a file ```method_receiver.so``` which is the shared object file to support the did_you_mean gem. This needs to be copied to the folder ```did_you_mean``` which you created in the  ```gem .so folder```
-
-B) ***ffi gem*** The shared object file in this case is called ```ffi_c.so``` It is copied to the ```gem .so folder```
-use the left arrow in the window where the ```method_receiver.so``` file was found to return to the search screen, and amend the search. Search for ```ffi*.so```
-IF you are using Ruby 2.2.* you will see several matches. Note that they are NOT all the same size. This is because this gem unfortunately builds with several versions of the file for different versions of Ruby. IT IS VERY IMPORTANT TO SELECT THE RIGHT ONE, which will be in a folder ```2.2``` Other versions which you DON'T want are in folders 1.8,1.9,2.0 and 2.1. Copy the correct version to 
-the ```gem .so folder``` If you are using Ruby 2.1.* the problem does not seem to arise, and although there are several matches to the search, they are all identical.
-
-C) ***rugged gem*** The shared object file in this case is ```rugged.so``` It is copied to the ```gem .so folder```
-use the left arrow in the window where the ```ffi_c.so``` file was found to return to the search screen, and amend the search. Search for ```rugged.so``` Select one of the matches and copy the file to the ```gem .so folder```
-
-At the end of this copying process the ```gem .so folder ``` which is 
-```
-c:\app\server\rb-native\windows\2.2.0\
-```
-(assuming you are using Ruby 2.2.*, or a path ending in 2.1.0 if using Ruby 2.1.*) will contain: ```ffi_c.so```, ```rugged.so``` and a folder named ```did_you_mean``` containing ```method_receiver.so```
-
-(Note nothing needs to be copied with the win32-process gem)
-
-That completes the ruby preparation work. Close the cmd and FileExplorer windows.
-
-
-### Preparing the Qt GUI
-From the **Start Button** select **All apps** and scroll down to **Visual Studio 2013**, and then to **Visual Studio Tools**. From the Window that opens **right click**  **VS2013 x86 Native Tools Command Prompt** and **Pin it to the Taskbar**. **Double click it** there to open a window which should be titled **VS2013 x86 Native Tools Command Prompt**.
-
-Type **path** in that window after the prompt and press the enter key.
-
-You will see a long string of folder locations which comprise the path associated with the window, which it will automatically search. It includes links to the various elements of visual studio. However, we have to add one more item, which is the path of the Qt bin directory.
-
-Since the Visual Studio prompt path is rebuilt each time a window is opened, I have found the convenient way to do this is to create a **batch file** which can be run each time to add the additional entry. Since I want to store this at the C:\ top level, we have to run the cmd window with administrative privileges to create it.
-Close the open Visual Studio Command Prompt window, then reopen it, holding down **Shift** and **Ctrl** when you do so. Say **Yes** to the popup window, and you will then have a cmd window with admin privileges. 
-
-```
-cd c:\
-notepad
-```
-
-In the open notepad window type
-```
-PATH=%PATH%;C:\Qt\Qt5.5.1\5.5\msvc2013\bin
-```
-
-Then select **save** and save the file as ```pathupdate.bat```, at the top level of ```c:\``` Make sure you select **All Files** for the type so the extension can be set to **.bat** and NOT **.txt**
-
-Close notepad and type ```dir``` (and press return) You should see the file ```pathupdate.bat``` listed.
-
-Close the cmd window and double click the icon on the taskbar to reopen it with "normal" privileges.
-
-```
-cd c:\
-pathupdate.bat
-```
-
-You should see the long path as before, but now with an additional entry ```C:\Qt\Qt5.5.1\5.5\msvc2013\bin``` at the end
-Leave this window open.
-
-Download **Qscintilla** from https://www.riverbankcomputing.com/software/qscintilla/download
-
-Select the ```Qscintilla-gpl-2.9.1.zip``` file to download
-When downloaded extract the ```Qscintilla-gpl-2.9.1``` folder to ```c:\```
-
-Return to the visual studio command window. 
-```
-cd c:\QScintilla-gpl-2.9.1\Qt4Qt5
-qmake qscintilla.pro
-nmake
-```
-(it will now be compiled)
-```
-nmake install
-```
-keep the cmd window open
-
-copy ```Qt4Qt5\release\moc_qsciscintilla.cpp``` and ```moc_qsciscintillabase.cpp``` to 
-```c:\sonic-pi\app\gui\qt\platform\win``` (There may be two files there already, but overwrite them)
-Best done using two FileExplorer windows as before.
-
-Now we do the main build of Sonic-Pi gui, using the open cmd window.
-```
-cd c:\sonic-pi
-.\app\gui\qt\win-build-app.bat
-```
-This should carry out the build. Don’t worry about various warnings en route.
-We now add some files from visual studio which will be needed at run time.
-Open two FileExplorer windows. In the first navigate to:
-
-```Local Disk (C:)> Program Files (x86) > Microsoft Visual Studio 12.0 > VC > redist > x86 > Microsoft.VC120.CRT```
-
-In the second to
-
-```Local Disk (C:)> sonic-pi> app > gui > qt > release```
-
-Copy msvcp120.dll and msvcr120.dll from the former to the latter.
-
-In the second window navigate to **sonic-pi.exe** and **right-click** it to create a shortcut. Drag the shortcut to the desktop. Do NOT attempt to run it yet.
-
-###  The final stage deals with SuperCollider
-Install SuperCollider from http://supercollider.github.io/download.html
-Select the **Win32 3.6.6** installer and download it
-
-Run the installer
-
-Download additional SuperCollider plugins from
-
-http://sourceforge.net/projects/sc3-plugins/files/sc3-plugins%20Windows/
-
-Select the latest version link at the top of the page and download
-```Looking for the latest version? Download sc3-plugins-3.6.0-win32.zip (10.3 MB)```
-Extract them in the download folder.
-
-We now copy files to the sonic-pi installation.
-
-With two FileExplorer windows navigate the first to ```Local Disk (C:) >Program Files (x86) > SuperCollider```
-
-And the second (destination) to ```Local Disk (C:)> sonic-pi > app > server > native > windows```
-
-Copy the ```plugins``` folder from the former to the latter.
-
-Copy all dll files **EXCEPT those starting with QT** from the former to the latter.
-
-Copy ```scsynth.exe``` from the former to the latter.
-
-Keep these windows open for the moment.
-
-Open the ```sc3-plugins-3.6.0-win32``` folder in the Downloads folder and navigate to ```SC3-plugins```.
-Copy all the *.scx files that folder into the ```plugins``` folder copied to destination folder in the previous step.
-
-Close the open FileExplorer windows.
-
-There is one final patch to install. The Ugen file associated with the Piano synth was updated in the summer, to eliminate a problem with the tuning. Unfortunately the current Ugen has NOT yet been updated for windows, and consequently we have to use a modified version of the MdaUgen. This can be downloaded from https://goo.gl/K316fw
-Extract the contents and follow the instructions in the readme file. Basically you replace the file ```sonic-pi-piano.scsyndef``` in ```c:\sonic-pi\etc\synthdefs\compiled``` with the one downloaded in the patch.
-
-(You may like to retain a copy of the original before overwriting it, or perhaps rename it to ```sonic-pi-piano.scsyndef.original```)
-
-### Finished!
-That should complete the installation of Sonic Pi.
-Try running it by double clicking the Sonic Pi shortcut on the desktop.

+# How to contribute
+
+- [Getting help](#getting-help-)
+- [Submitting bug reports](#submitting-bug-reports-)
+- [Contributing code](#contributing-code-)
+
+## Getting help
+
+Community discussion, questions, and informal bug reporting is done on the
+[CodeMirror Google group](http://groups.google.com/group/codemirror).
+
+## Submitting bug reports
+
+The preferred way to report bugs is to use the
+[GitHub issue tracker](http://github.com/marijnh/CodeMirror/issues). Before
+reporting a bug, read these pointers.
+
+**Note:** The issue tracker is for *bugs*, not requests for help. Questions
+should be asked on the
+[CodeMirror Google group](http://groups.google.com/group/codemirror) instead.
+
+### Reporting bugs effectively
+
+- CodeMirror is maintained by volunteers. They don't owe you anything, so be
+  polite. Reports with an indignant or belligerent tone tend to be moved to the
+  bottom of the pile.
+
+- Include information about **the browser in which the problem occurred**. Even
+  if you tested several browsers, and the problem occurred in all of them,
+  mention this fact in the bug report. Also include browser version numbers and
+  the operating system that you're on.
+
+- Mention which release of CodeMirror you're using. Preferably, try also with
+  the current development snapshot, to ensure the problem has not already been
+  fixed.
+
+- Mention very precisely what went wrong. "X is broken" is not a good bug
+  report. What did you expect to happen? What happened instead? Describe the
+  exact steps a maintainer has to take to make the problem occur. We can not
+  fix something that we can not observe.
+
+- If the problem can not be reproduced in any of the demos included in the
+  CodeMirror distribution, please provide an HTML document that demonstrates
+  the problem. The best way to do this is to go to
+  [jsbin.com](http://jsbin.com/ihunin/edit), enter it there, press save, and
+  include the resulting link in your bug report.
+
+## Contributing code
+
+- Make sure you have a [GitHub Account](https://github.com/signup/free)
+- Fork [CodeMirror](https://github.com/marijnh/CodeMirror/)
+  ([how to fork a repo](https://help.github.com/articles/fork-a-repo))
+- Make your changes
+- If your changes are easy to test or likely to regress, add tests.
+  Tests for the core go into `test/test.js`, some modes have their own
+  test suite under `mode/XXX/test.js`. Feel free to add new test
+  suites to modes that don't have one yet (be sure to link the new
+  tests into `test/index.html`).
+- Follow the general code style of the rest of the project (see
+  below). Run `bin/lint` to verify that the linter is happy.
+- Make sure all tests pass. Visit `test/index.html` in your browser to
+  run them.
+- Submit a pull request
+([how to create a pull request](https://help.github.com/articles/fork-a-repo))
+
+### Coding standards
+
+- 2 spaces per indentation level, no tabs.
+- Include semicolons after statements.
+- Note that the linter (`bin/lint`) which is run after each commit
+  complains about unused variables and functions. Prefix their names
+  with an underscore to muffle it.

+ * Tag-closer extension for CodeMirror.

+ * configure its behavior.
+ *
+ * These are supported options:
+ *
+ * `whenClosing` (default true)
+ *   Whether to autoclose when the '/' of a closing tag is typed.
+ * `whenOpening` (default true)
+ *   Whether to autoclose the tag when the final '>' of an opening
+ *   tag is typed.
+ * `dontCloseTags` (default is empty tags for HTML, none for XML)
+ *   An array of tag names that should not be autoclosed.
+ * `indentTags` (default is block tags for HTML, none for XML)
+ *   An array of tag names that should, when opened, cause a
+ *   blank line to be added inside the tag, and the blank line and
+ *   closing line to be indented.
+ *
+ * See demos/closetag.html for a usage example.

+// Glue code between CodeMirror and Tern.
+//
+// Create a CodeMirror.TernServer to wrap an actual Tern server,
+// register open documents (CodeMirror.Doc instances) with it, and
+// call its methods to activate the assisting functions that Tern
+// provides.
+//
+// Options supported (all optional):
+// * defs: An array of JSON definition data structures.
+// * plugins: An object mapping plugin names to configuration
+//   options.
+// * getFile: A function(name, c) that can be used to access files in
+//   the project that haven't been loaded yet. Simply do c(null) to
+//   indicate that a file is not available.
+// * fileFilter: A function(value, docName, doc) that will be applied
+//   to documents before passing them on to Tern.
+// * switchToDoc: A function(name) that should, when providing a
+//   multi-file view, switch the view or focus to the named file.
+// * showError: A function(editor, message) that can be used to
+//   override the way errors are displayed.
+// * completionTip: Customize the content in tooltips for completions.
+//   Is passed a single argument—the completion's data as returned by
+//   Tern—and may return a string, DOM node, or null to indicate that
+//   no tip should be shown. By default the docstring is shown.
+// * typeTip: Like completionTip, but for the tooltips shown for type
+//   queries.
+// * responseFilter: A function(doc, query, request, error, data) that
+//   will be applied to the Tern responses before treating them
+//
+//
+// It is possible to run the Tern server in a web worker by specifying
+// these additional options:
+// * useWorker: Set to true to enable web worker mode. You'll probably
+//   want to feature detect the actual value you use here, for example
+//   !!window.Worker.
+// * workerScript: The main script of the worker. Point this to
+//   wherever you are hosting worker.js from this directory.
+// * workerDeps: An array of paths pointing (relative to workerScript)
+//   to the Acorn and Tern libraries and any Tern plugins you want to
+//   load. Or, if you minified those into a single script and included
+//   them in the workerScript, simply leave this undefined.

+  <h2 id="overview">Overview</h2>
+
+  <p>CodeMirror is a code-editor component that can be embedded in Web pages. The core library provides <em>only</em> the editor component, no accompanying buttons, auto-completion, or other IDE functionality. It does provide a rich API on top of which such functionality can be straightforwardly implemented. See the <a href="#addons">add-ons</a> included in the distribution, and the <a href="https://github.com/jagthedrummer/codemirror-ui">CodeMirror UI</a> project, for reusable implementations of extra features.</p>
+
+  <p>CodeMirror works with language-specific modes. Modes are JavaScript programs that help color (and optionally indent) text written in a given language. The distribution comes with a number of modes (see the <a href="../mode/"><code>mode/</code></a> directory), and it isn't hard to <a href="#modeapi">write new ones</a> for other languages.</p>
+</body>
+</textarea></form>
+
+    <p>This page uses a hack on top of the <code>"renderLine"</code>
+    event to make wrapped text line up with the base indentation of
+    the line.</p>
+
+    <script>
+      var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
+        lineNumbers: true,
+        lineWrapping: true,
+        mode: "text/html"
+      });
+      var charWidth = editor.defaultCharWidth(), basePadding = 4;
+      editor.on("renderLine", function(cm, line, elt) {
+        var off = CodeMirror.countColumn(line.text, null, cm.getOption("tabSize")) * charWidth;
+        elt.style.textIndent = "-" + off + "px";
+        elt.style.paddingLeft = (basePadding + off) + "px";
+      });
+      editor.refresh();

+<h2>Script compression helper</h2>
+
+    <p>To optimize loading CodeMirror, especially when including a
+    bunch of different modes, it is recommended that you combine and
+    minify (and preferably also gzip) the scripts. This page makes
+    those first two steps very easy. Simply select the version and
+    scripts you need in the form below, and
+    click <strong>Compress</strong> to download the minified script
+    file.</p>

+<h2 id=top>(Re-) Implementing A Syntax-Highlighting Editor in JavaScript</h2>
+
+<p style="font-size: 85%" id="intro">
+  <strong>Topic:</strong> JavaScript, code editor implementation<br>
+  <strong>Author:</strong> Marijn Haverbeke<br>
+  <strong>Date:</strong> March 2nd 2011 (updated November 13th 2011)
+</p>
+
+<p style="padding: 0 3em 0 2em"><strong>Caution</strong>: this text was written briefly after
+version 2 was initially written. It no longer (even including the
+update at the bottom) fully represents the current implementation. I'm
+leaving it here as a historic document. For more up-to-date
+information, look at the entries
+tagged <a href="http://marijnhaverbeke.nl/blog/#cm-internals">cm-internals</a>
+on my blog.</p>
+
+<p>This is a followup to
+my <a href="http://codemirror.net/story.html">Brutal Odyssey to the
+Dark Side of the DOM Tree</a> story. That one describes the
+mind-bending process of implementing (what would become) CodeMirror 1.
+This one describes the internals of CodeMirror 2, a complete rewrite
+and rethink of the old code base. I wanted to give this piece another
+Hunter Thompson copycat subtitle, but somehow that would be out of
+place—the process this time around was one of straightforward
+engineering, requiring no serious mind-bending whatsoever.</p>
+
+<p>So, what is wrong with CodeMirror 1? I'd estimate, by mailing list
+activity and general search-engine presence, that it has been
+integrated into about a thousand systems by now. The most prominent
+one, since a few weeks,
+being <a href="http://googlecode.blogspot.com/2011/01/make-quick-fixes-quicker-on-google.html">Google
+code's project hosting</a>. It works, and it's being used widely.</p>
+
+<p>Still, I did not start replacing it because I was bored. CodeMirror
+1 was heavily reliant on <code>designMode</code>
+or <code>contentEditable</code> (depending on the browser). Neither of
+these are well specified (HTML5 tries
+to <a href="http://www.w3.org/TR/html5/editing.html#contenteditable">specify</a>
+their basics), and, more importantly, they tend to be one of the more
+obscure and buggy areas of browser functionality—CodeMirror, by using
+this functionality in a non-typical way, was constantly running up
+against browser bugs. WebKit wouldn't show an empty line at the end of
+the document, and in some releases would suddenly get unbearably slow.
+Firefox would show the cursor in the wrong place. Internet Explorer
+would insist on linkifying everything that looked like a URL or email
+address, a behaviour that can't be turned off. Some bugs I managed to
+work around (which was often a frustrating, painful process), others,
+such as the Firefox cursor placement, I gave up on, and had to tell
+user after user that they were known problems, but not something I
+could help.</p>
+
+<p>Also, there is the fact that <code>designMode</code> (which seemed
+to be less buggy than <code>contentEditable</code> in Webkit and
+Firefox, and was thus used by CodeMirror 1 in those browsers) requires
+a frame. Frames are another tricky area. It takes some effort to
+prevent getting tripped up by domain restrictions, they don't
+initialize synchronously, behave strangely in response to the back
+button, and, on several browsers, can't be moved around the DOM
+without having them re-initialize. They did provide a very nice way to
+namespace the library, though—CodeMirror 1 could freely pollute the
+namespace inside the frame.</p>
+
+<p>Finally, working with an editable document means working with
+selection in arbitrary DOM structures. Internet Explorer (8 and
+before) has an utterly different (and awkward) selection API than all
+of the other browsers, and even among the different implementations of
+<code>document.selection</code>, details about how exactly a selection
+is represented vary quite a bit. Add to that the fact that Opera's
+selection support tended to be very buggy until recently, and you can
+imagine why CodeMirror 1 contains 700 lines of selection-handling
+code.</p>
+
+<p>And that brings us to the main issue with the CodeMirror 1
+code base: The proportion of browser-bug-workarounds to real
+application code was getting dangerously high. By building on top of a
+few dodgy features, I put the system in a vulnerable position—any
+incompatibility and bugginess in these features, I had to paper over
+with my own code. Not only did I have to do some serious stunt-work to
+get it to work on older browsers (as detailed in the
+previous <a href="http://codemirror.net/story.html">story</a>), things
+also kept breaking in newly released versions, requiring me to come up
+with <em>new</em> scary hacks in order to keep up. This was starting
+to lose its appeal.</p>
+
+<section id=approach>
+  <h2>General Approach</h2>
+
+<p>What CodeMirror 2 does is try to sidestep most of the hairy hacks
+that came up in version 1. I owe a lot to the
+<a href="http://ace.ajax.org">ACE</a> editor for inspiration on how to
+approach this.</p>
+
+<p>I absolutely did not want to be completely reliant on key events to
+generate my input. Every JavaScript programmer knows that key event
+information is horrible and incomplete. Some people (most awesomely
+Mihai Bazon with <a href="http://ymacs.org">Ymacs</a>) have been able
+to build more or less functioning editors by directly reading key
+events, but it takes a lot of work (the kind of never-ending, fragile
+work I described earlier), and will never be able to properly support
+things like multi-keystoke international character
+input. <a href="#keymap" class="update">[see below for caveat]</a></p>
+
+<p>So what I do is focus a hidden textarea, and let the browser
+believe that the user is typing into that. What we show to the user is
+a DOM structure we built to represent his document. If this is updated
+quickly enough, and shows some kind of believable cursor, it feels
+like a real text-input control.</p>
+
+<p>Another big win is that this DOM representation does not have to
+span the whole document. Some CodeMirror 1 users insisted that they
+needed to put a 30 thousand line XML document into CodeMirror. Putting
+all that into the DOM takes a while, especially since, for some
+reason, an editable DOM tree is slower than a normal one on most
+browsers. If we have full control over what we show, we must only
+ensure that the visible part of the document has been added, and can
+do the rest only when needed. (Fortunately, the <code>onscroll</code>
+event works almost the same on all browsers, and lends itself well to
+displaying things only as they are scrolled into view.)</p>
+</section>
+<section id="input">
+  <h2>Input</h2>
+
+<p>ACE uses its hidden textarea only as a text input shim, and does
+all cursor movement and things like text deletion itself by directly
+handling key events. CodeMirror's way is to let the browser do its
+thing as much as possible, and not, for example, define its own set of
+key bindings. One way to do this would have been to have the whole
+document inside the hidden textarea, and after each key event update
+the display DOM to reflect what's in that textarea.</p>
+
+<p>That'd be simple, but it is not realistic. For even medium-sized
+document the editor would be constantly munging huge strings, and get
+terribly slow. What CodeMirror 2 does is put the current selection,
+along with an extra line on the top and on the bottom, into the
+textarea.</p>
+
+<p>This means that the arrow keys (and their ctrl-variations), home,
+end, etcetera, do not have to be handled specially. We just read the
+cursor position in the textarea, and update our cursor to match it.
+Also, copy and paste work pretty much for free, and people get their
+native key bindings, without any special work on my part. For example,
+I have emacs key bindings configured for Chrome and Firefox. There is
+no way for a script to detect this. <a class="update"
+href="#keymap">[no longer the case]</a></p>
+
+<p>Of course, since only a small part of the document sits in the
+textarea, keys like page up and ctrl-end won't do the right thing.
+CodeMirror is catching those events and handling them itself.</p>
+</section>
+<section id="selection">
+  <h2>Selection</h2>
+
+<p>Getting and setting the selection range of a textarea in modern
+browsers is trivial—you just use the <code>selectionStart</code>
+and <code>selectionEnd</code> properties. On IE you have to do some
+insane stuff with temporary ranges and compensating for the fact that
+moving the selection by a 'character' will treat \r\n as a single
+character, but even there it is possible to build functions that
+reliably set and get the selection range.</p>
+
+<p>But consider this typical case: When I'm somewhere in my document,
+press shift, and press the up arrow, something gets selected. Then, if
+I, still holding shift, press the up arrow again, the top of my
+selection is adjusted. The selection remembers where its <em>head</em>
+and its <em>anchor</em> are, and moves the head when we shift-move.
+This is a generally accepted property of selections, and done right by
+every editing component built in the past twenty years.</p>
+
+<p>But not something that the browser selection APIs expose.</p>
+
+<p>Great. So when someone creates an 'upside-down' selection, the next
+time CodeMirror has to update the textarea, it'll re-create the
+selection as an 'upside-up' selection, with the anchor at the top, and
+the next cursor motion will behave in an unexpected way—our second
+up-arrow press in the example above will not do anything, since it is
+interpreted in exactly the same way as the first.</p>
+
+<p>No problem. We'll just, ehm, detect that the selection is
+upside-down (you can tell by the way it was created), and then, when
+an upside-down selection is present, and a cursor-moving key is
+pressed in combination with shift, we quickly collapse the selection
+in the textarea to its start, allow the key to take effect, and then
+combine its new head with its old anchor to get the <em>real</em>
+selection.</p>
+
+<p>In short, scary hacks could not be avoided entirely in CodeMirror
+2.</p>
+
+<p>And, the observant reader might ask, how do you even know that a
+key combo is a cursor-moving combo, if you claim you support any
+native key bindings? Well, we don't, but we can learn. The editor
+keeps a set known cursor-movement combos (initialized to the
+predictable defaults), and updates this set when it observes that
+pressing a certain key had (only) the effect of moving the cursor.
+This, of course, doesn't work if the first time the key is used was
+for extending an inverted selection, but it works most of the
+time.</p>
+</section>
+<section id="update">
+  <h2>Intelligent Updating</h2>
+
+<p>One thing that always comes up when you have a complicated internal
+state that's reflected in some user-visible external representation
+(in this case, the displayed code and the textarea's content) is
+keeping the two in sync. The naive way is to just update the display
+every time you change your state, but this is not only error prone
+(you'll forget), it also easily leads to duplicate work on big,
+composite operations. Then you start passing around flags indicating
+whether the display should be updated in an attempt to be efficient
+again and, well, at that point you might as well give up completely.</p>
+
+<p>I did go down that road, but then switched to a much simpler model:
+simply keep track of all the things that have been changed during an
+action, and then, only at the end, use this information to update the
+user-visible display.</p>
+
+<p>CodeMirror uses a concept of <em>operations</em>, which start by
+calling a specific set-up function that clears the state and end by
+calling another function that reads this state and does the required
+updating. Most event handlers, and all the user-visible methods that
+change state are wrapped like this. There's a method
+called <code>operation</code> that accepts a function, and returns
+another function that wraps the given function as an operation.</p>
+
+<p>It's trivial to extend this (as CodeMirror does) to detect nesting,
+and, when an operation is started inside an operation, simply
+increment the nesting count, and only do the updating when this count
+reaches zero again.</p>
+
+<p>If we have a set of changed ranges and know the currently shown
+range, we can (with some awkward code to deal with the fact that
+changes can add and remove lines, so we're dealing with a changing
+coordinate system) construct a map of the ranges that were left
+intact. We can then compare this map with the part of the document
+that's currently visible (based on scroll offset and editor height) to
+determine whether something needs to be updated.</p>
+
+<p>CodeMirror uses two update algorithms—a full refresh, where it just
+discards the whole part of the DOM that contains the edited text and
+rebuilds it, and a patch algorithm, where it uses the information
+about changed and intact ranges to update only the out-of-date parts
+of the DOM. When more than 30 percent (which is the current heuristic,
+might change) of the lines need to be updated, the full refresh is
+chosen (since it's faster to do than painstakingly finding and
+updating all the changed lines), in the other case it does the
+patching (so that, if you scroll a line or select another character,
+the whole screen doesn't have to be
+re-rendered). <span class="update">[the full-refresh
+algorithm was dropped, it wasn't really faster than the patching
+one]</span></p>
+
+<p>All updating uses <code>innerHTML</code> rather than direct DOM
+manipulation, since that still seems to be by far the fastest way to
+build documents. There's a per-line function that combines the
+highlighting, <a href="manual.html#markText">marking</a>, and
+selection info for that line into a snippet of HTML. The patch updater
+uses this to reset individual lines, the refresh updater builds an
+HTML chunk for the whole visible document at once, and then uses a
+single <code>innerHTML</code> update to do the refresh.</p>
+</section>
+<section id="parse">
+  <h2>Parsers can be Simple</h2>
+
+<p>When I wrote CodeMirror 1, I
+thought <a href="http://codemirror.net/story.html#parser">interruptable
+parsers</a> were a hugely scary and complicated thing, and I used a
+bunch of heavyweight abstractions to keep this supposed complexity
+under control: parsers
+were <a href="http://bob.pythonmac.org/archives/2005/07/06/iteration-in-javascript/">iterators</a>
+that consumed input from another iterator, and used funny
+closure-resetting tricks to copy and resume themselves.</p>
+
+<p>This made for a rather nice system, in that parsers formed strictly
+separate modules, and could be composed in predictable ways.
+Unfortunately, it was quite slow (stacking three or four iterators on
+top of each other), and extremely intimidating to people not used to a
+functional programming style.</p>
+
+<p>With a few small changes, however, we can keep all those
+advantages, but simplify the API and make the whole thing less
+indirect and inefficient. CodeMirror
+2's <a href="manual.html#modeapi">mode API</a> uses explicit state
+objects, and makes the parser/tokenizer a function that simply takes a
+state and a character stream abstraction, advances the stream one
+token, and returns the way the token should be styled. This state may
+be copied, optionally in a mode-defined way, in order to be able to
+continue a parse at a given point. Even someone who's never touched a
+lambda in his life can understand this approach. Additionally, far
+fewer objects are allocated in the course of parsing now.</p>
+
+<p>The biggest speedup comes from the fact that the parsing no longer
+has to touch the DOM though. In CodeMirror 1, on an older browser, you
+could <em>see</em> the parser work its way through the document,
+managing some twenty lines in each 50-millisecond time slice it got. It
+was reading its input from the DOM, and updating the DOM as it went
+along, which any experienced JavaScript programmer will immediately
+spot as a recipe for slowness. In CodeMirror 2, the parser usually
+finishes the whole document in a single 100-millisecond time slice—it
+manages some 1500 lines during that time on Chrome. All it has to do
+is munge strings, so there is no real reason for it to be slow
+anymore.</p>
+</section>
+<section id="summary">
+  <h2>What Gives?</h2>
+
+<p>Given all this, what can you expect from CodeMirror 2?</p>
+
+<ul>
+
+<li><strong>Small.</strong> the base library is
+some <span class="update">45k</span> when minified
+now, <span class="update">17k</span> when gzipped. It's smaller than
+its own logo.</li>
+
+<li><strong>Lightweight.</strong> CodeMirror 2 initializes very
+quickly, and does almost no work when it is not focused. This means
+you can treat it almost like a textarea, have multiple instances on a
+page without trouble.</li>
+
+<li><strong>Huge document support.</strong> Since highlighting is
+really fast, and no DOM structure is being built for non-visible
+content, you don't have to worry about locking up your browser when a
+user enters a megabyte-sized document.</li>
+
+<li><strong>Extended API.</strong> Some things kept coming up in the
+mailing list, such as marking pieces of text or lines, which were
+extremely hard to do with CodeMirror 1. The new version has proper
+support for these built in.</li>
+
+<li><strong>Tab support.</strong> Tabs inside editable documents were,
+for some reason, a no-go. At least six different people announced they
+were going to add tab support to CodeMirror 1, none survived (I mean,
+none delivered a working version). CodeMirror 2 no longer removes tabs
+from your document.</li>
+
+<li><strong>Sane styling.</strong> <code>iframe</code> nodes aren't
+really known for respecting document flow. Now that an editor instance
+is a plain <code>div</code> element, it is much easier to size it to
+fit the surrounding elements. You don't even have to make it scroll if
+you do not <a href="../demo/resize.html">want to</a>.</li>
+
+</ul>
+
+<p>On the downside, a CodeMirror 2 instance is <em>not</em> a native
+editable component. Though it does its best to emulate such a
+component as much as possible, there is functionality that browsers
+just do not allow us to hook into. Doing select-all from the context
+menu, for example, is not currently detected by CodeMirror.</p>
+
+<p id="changes" style="margin-top: 2em;"><span style="font-weight:
+bold">[Updates from November 13th 2011]</span> Recently, I've made
+some changes to the codebase that cause some of the text above to no
+longer be current. I've left the text intact, but added markers at the
+passages that are now inaccurate. The new situation is described
+below.</p>
+</section>
+<section id="btree">
+  <h2>Content Representation</h2>
+
+<p>The original implementation of CodeMirror 2 represented the
+document as a flat array of line objects. This worked well—splicing
+arrays will require the part of the array after the splice to be
+moved, but this is basically just a simple <code>memmove</code> of a
+bunch of pointers, so it is cheap even for huge documents.</p>
+
+<p>However, I recently added line wrapping and code folding (line
+collapsing, basically). Once lines start taking up a non-constant
+amount of vertical space, looking up a line by vertical position
+(which is needed when someone clicks the document, and to determine
+the visible part of the document during scrolling) can only be done
+with a linear scan through the whole array, summing up line heights as
+you go. Seeing how I've been going out of my way to make big documents
+fast, this is not acceptable.</p>
+
+<p>The new representation is based on a B-tree. The leaves of the tree
+contain arrays of line objects, with a fixed minimum and maximum size,
+and the non-leaf nodes simply hold arrays of child nodes. Each node
+stores both the amount of lines that live below them and the vertical
+space taken up by these lines. This allows the tree to be indexed both
+by line number and by vertical position, and all access has
+logarithmic complexity in relation to the document size.</p>
+
+<p>I gave line objects and tree nodes parent pointers, to the node
+above them. When a line has to update its height, it can simply walk
+these pointers to the top of the tree, adding or subtracting the
+difference in height from each node it encounters. The parent pointers
+also make it cheaper (in complexity terms, the difference is probably
+tiny in normal-sized documents) to find the current line number when
+given a line object. In the old approach, the whole document array had
+to be searched. Now, we can just walk up the tree and count the sizes
+of the nodes coming before us at each level.</p>
+
+<p>I chose B-trees, not regular binary trees, mostly because they
+allow for very fast bulk insertions and deletions. When there is a big
+change to a document, it typically involves adding, deleting, or
+replacing a chunk of subsequent lines. In a regular balanced tree, all
+these inserts or deletes would have to be done separately, which could
+be really expensive. In a B-tree, to insert a chunk, you just walk
+down the tree once to find where it should go, insert them all in one
+shot, and then break up the node if needed. This breaking up might
+involve breaking up nodes further up, but only requires a single pass
+back up the tree. For deletion, I'm somewhat lax in keeping things
+balanced—I just collapse nodes into a leaf when their child count goes
+below a given number. This means that there are some weird editing
+patterns that may result in a seriously unbalanced tree, but even such
+an unbalanced tree will perform well, unless you spend a day making
+strangely repeating edits to a really big document.</p>
+</section>
+<section id="keymap">
+  <h2>Keymaps</h2>
+
+<p><a href="#approach">Above</a>, I claimed that directly catching key
+events for things like cursor movement is impractical because it
+requires some browser-specific kludges. I then proceeded to explain
+some awful <a href="#selection">hacks</a> that were needed to make it
+possible for the selection changes to be detected through the
+textarea. In fact, the second hack is about as bad as the first.</p>
+
+<p>On top of that, in the presence of user-configurable tab sizes and
+collapsed and wrapped lines, lining up cursor movement in the textarea
+with what's visible on the screen becomes a nightmare. Thus, I've
+decided to move to a model where the textarea's selection is no longer
+depended on.</p>
+
+<p>So I moved to a model where all cursor movement is handled by my
+own code. This adds support for a goal column, proper interaction of
+cursor movement with collapsed lines, and makes it possible for
+vertical movement to move through wrapped lines properly, instead of
+just treating them like non-wrapped lines.</p>
+
+<p>The key event handlers now translate the key event into a string,
+something like <code>Ctrl-Home</code> or <code>Shift-Cmd-R</code>, and
+use that string to look up an action to perform. To make keybinding
+customizable, this lookup goes through
+a <a href="manual.html#option_keyMap">table</a>, using a scheme that
+allows such tables to be chained together (for example, the default
+Mac bindings fall through to a table named 'emacsy', which defines
+basic Emacs-style bindings like <code>Ctrl-F</code>, and which is also
+used by the custom Emacs bindings).</p>
+
+<p>A new
+option <a href="manual.html#option_extraKeys"><code>extraKeys</code></a>
+allows ad-hoc keybindings to be defined in a much nicer way than what
+was possible with the
+old <a href="manual.html#option_onKeyEvent"><code>onKeyEvent</code></a>
+callback. You simply provide an object mapping key identifiers to
+functions, instead of painstakingly looking at raw key events.</p>
+
+<p>Built-in commands map to strings, rather than functions, for
+example <code>"goLineUp"</code> is the default action bound to the up
+arrow key. This allows new keymaps to refer to them without
+duplicating any code. New commands can be defined by assigning to
+the <code>CodeMirror.commands</code> object, which maps such commands
+to functions.</p>
+
+<p>The hidden textarea now only holds the current selection, with no
+extra characters around it. This has a nice advantage: polling for
+input becomes much, much faster. If there's a big selection, this text
+does not have to be read from the textarea every time—when we poll,
+just noticing that something is still selected is enough to tell us
+that no new text was typed.</p>
+
+<p>The reason that cheap polling is important is that many browsers do
+not fire useful events on IME (input method engine) input, which is
+the thing where people inputting a language like Japanese or Chinese
+use multiple keystrokes to create a character or sequence of
+characters. Most modern browsers fire <code>input</code> when the
+composing is finished, but many don't fire anything when the character
+is updated <em>during</em> composition. So we poll, whenever the
+editor is focused, to provide immediate updates of the display.</p>

+    </h2>
+
+    <p>CodeMirror is a code-editor component that can be embedded in
+    Web pages. The core library provides <em>only</em> the editor
+    component, no accompanying buttons, auto-completion, or other IDE
+    functionality. It does provide a rich API on top of which such
+    functionality can be straightforwardly implemented. See
+    the <a href="#addons">addons</a> included in the distribution,
+    and the <a href="https://github.com/marijnh/CodeMirror/wiki/CodeMirror-addons">list
+    of externally hosted addons</a>, for reusable
+    implementations of extra features.</p>
+
+    <p>CodeMirror works with language-specific modes. Modes are
+    JavaScript programs that help color (and optionally indent) text
+    written in a given language. The distribution comes with a number
+    of modes (see the <a href="../mode/"><code>mode/</code></a>
+    directory), and it isn't hard to <a href="#modeapi">write new
+    ones</a> for other languages.</p>
+</section>
+
+<section id=usage>
+    <h2>Basic Usage</h2>
+
+    <p>The easiest way to use CodeMirror is to simply load the script
+    and style sheet found under <code>lib/</code> in the distribution,
+    plus a mode script from one of the <code>mode/</code> directories.
+    (See <a href="compress.html">the compression helper</a> for an
+    easy way to combine scripts.) For example:</p>
+
+    <pre data-lang="text/html"><script src="lib/codemirror.js"></script>
+<link rel="stylesheet" href="../lib/codemirror.css">
+<script src="mode/javascript/javascript.js"></script></pre>
+
+    <p>(Alternatively, use a module loader. <a href="#modloader">More
+    about that later.</a>)</p>
+
+    <p>Having done this, an editor instance can be created like
+    this:</p>
+
+    <pre data-lang="javascript">var myCodeMirror = CodeMirror(document.body);</pre>
+
+    <p>The editor will be appended to the document body, will start
+    empty, and will use the mode that we loaded. To have more control
+    over the new editor, a configuration object can be passed
+    to <a href="#CodeMirror"><code>CodeMirror</code></a> as a second
+    argument:</p>
+
+    <pre data-lang="javascript">var myCodeMirror = CodeMirror(document.body, {
+  value: "function myScript(){return 100;}\n",
+  mode:  "javascript"
+});</pre>
+
+    <p>This will initialize the editor with a piece of code already in
+    it, and explicitly tell it to use the JavaScript mode (which is
+    useful when multiple modes are loaded).
+    See <a href="#config">below</a> for a full discussion of the
+    configuration options that CodeMirror accepts.</p>
+
+    <p>In cases where you don't want to append the editor to an
+    element, and need more control over the way it is inserted, the
+    first argument to the <code>CodeMirror</code> function can also
+    be a function that, when given a DOM element, inserts it into the
+    document somewhere. This could be used to, for example, replace a
+    textarea with a real editor:</p>
+
+    <pre data-lang="javascript">var myCodeMirror = CodeMirror(function(elt) {
+  myTextArea.parentNode.replaceChild(elt, myTextArea);
+}, {value: myTextArea.value});</pre>
+
+    <p>However, for this use case, which is a common way to use
+    CodeMirror, the library provides a much more powerful
+    shortcut:</p>
+
+    <pre data-lang="javascript">var myCodeMirror = CodeMirror.fromTextArea(myTextArea);</pre>
+
+    <p>This will, among other things, ensure that the textarea's value
+    is updated with the editor's contents when the form (if it is part
+    of a form) is submitted. See the <a href="#fromTextArea">API
+    reference</a> for a full description of this method.</p>
+
+    <h3 id=modloader>Module loaders</h3>
+
+    <p>The files in the CodeMirror distribution contain shims for
+    loading them (and their dependencies) in AMD or CommonJS
+    environments. If the variables <code>exports</code>
+    and <code>module</code> exist and have type object, CommonJS-style
+    require will be used. If not, but there is a
+    function <code>define</code> with an <code>amd</code> property
+    present, AMD-style (RequireJS) will be used.</p>
+
+    <p>It is possible to
+    use <a href="http://browserify.org/">Browserify</a> or similar
+    tools to statically build modules using CodeMirror. Alternatively,
+    use <a href="http://requirejs.org/">RequireJS</a> to dynamically
+    load dependencies at runtime. Both of these approaches have the
+    advantage that they don't use the global namespace and can, thus,
+    do things like load multiple versions of CodeMirror alongside each
+    other.</p>
+
+    <p>Here's a simple example of using RequireJS to load CodeMirror:</p>
+
+    <pre data-lang="javascript">require([
+  "cm/lib/codemirror", "cm/mode/htmlmixed/htmlmixed"
+], function(CodeMirror) {
+  CodeMirror.fromTextArea(document.getElementById("code"), {
+    lineNumbers: true,
+    mode: "htmlmixed"
+  });
+});</pre>
+
+    <p>It will automatically load the modes that the mixed HTML mode
+    depends on (XML, JavaScript, and CSS).</p>
+
+</section>
+
+<section id=config>
+    <h2>Configuration</h2>
+
+    <p>Both the <a href="#CodeMirror"><code>CodeMirror</code></a>
+    function and its <code>fromTextArea</code> method take as second
+    (optional) argument an object containing configuration options.
+    Any option not supplied like this will be taken
+    from <a href="#defaults"><code>CodeMirror.defaults</code></a>, an
+    object containing the default options. You can update this object
+    to change the defaults on your page.</p>
+
+    <p>Options are not checked in any way, so setting bogus option
+    values is bound to lead to odd errors.</p>
+
+    <p>These are the supported options:</p>
+
+    <dl>
+      <dt id="option_value"><code><strong>value</strong>: string|CodeMirror.Doc</code></dt>
+      <dd>The starting value of the editor. Can be a string, or
+      a <a href="#api_doc">document object</a>.</dd>
+
+      <dt id="option_mode"><code><strong>mode</strong>: string|object</code></dt>
+      <dd>The mode to use. When not given, this will default to the
+      first mode that was loaded. It may be a string, which either
+      simply names the mode or is
+      a <a href="http://en.wikipedia.org/wiki/MIME">MIME</a> type
+      associated with the mode. Alternatively, it may be an object
+      containing configuration options for the mode, with
+      a <code>name</code> property that names the mode (for
+      example <code>{name: "javascript", json: true}</code>). The demo
+      pages for each mode contain information about what configuration
+      parameters the mode supports. You can ask CodeMirror which modes
+      and MIME types have been defined by inspecting
+      the <code>CodeMirror.modes</code>
+      and <code>CodeMirror.mimeModes</code> objects. The first maps
+      mode names to their constructors, and the second maps MIME types
+      to mode specs.</dd>
+
+      <dt id="option_theme"><code><strong>theme</strong>: string</code></dt>
+      <dd>The theme to style the editor with. You must make sure the
+      CSS file defining the corresponding <code>.cm-s-[name]</code>
+      styles is loaded (see
+      the <a href="../theme/"><code>theme</code></a> directory in the
+      distribution). The default is <code>"default"</code>, for which
+      colors are included in <code>codemirror.css</code>. It is
+      possible to use multiple theming classes at once—for
+      example <code>"foo bar"</code> will assign both
+      the <code>cm-s-foo</code> and the <code>cm-s-bar</code> classes
+      to the editor.</dd>
+
+      <dt id="option_indentUnit"><code><strong>indentUnit</strong>: integer</code></dt>
+      <dd>How many spaces a block (whatever that means in the edited
+      language) should be indented. The default is 2.</dd>
+
+      <dt id="option_smartIndent"><code><strong>smartIndent</strong>: boolean</code></dt>
+      <dd>Whether to use the context-sensitive indentation that the
+      mode provides (or just indent the same as the line before).
+      Defaults to true.</dd>
+
+      <dt id="option_tabSize"><code><strong>tabSize</strong>: integer</code></dt>

+      <dd>By default, CodeMirror will combine adjacent tokens into a

+      right-to-left text, markers, or other irregular elements are

+    <h2>Events</h2>
+
+    <p>Various CodeMirror-related objects emit events, which allow
+    client code to react to various situations. Handlers for such
+    events can be registered with the <a href="#on"><code>on</code></a>
+    and <a href="#off"><code>off</code></a> methods on the objects
+    that the event fires on. To fire your own events,
+    use <code>CodeMirror.signal(target, name, args...)</code>,
+    where <code>target</code> is a non-DOM-node object.</p>
+
+    <p>An editor instance fires the following events.
+    The <code>instance</code> argument always refers to the editor
+    itself.</p>
+
+    <dl>
+      <dt id="event_change"><code><strong>"change"</strong> (instance: CodeMirror, changeObj: object)</code></dt>
+      <dd>Fires every time the content of the editor is changed.
+      The <code>changeObj</code> is a <code>{from, to, text, removed,
+      origin}</code> object containing information about the changes
+      that occurred as second argument. <code>from</code>
+      and <code>to</code> are the positions (in the pre-change
+      coordinate system) where the change started and ended (for
+      example, it might be <code>{ch:0, line:18}</code> if the
+      position is at the beginning of line #19). <code>text</code> is
+      an array of strings representing the text that replaced the
+      changed range (split by line). <code>removed</code> is the text
+      that used to be between <code>from</code> and <code>to</code>,
+      which is overwritten by this change.</dd>
+
+      <dt id="event_changes"><code><strong>"changes"</strong> (instance: CodeMirror, changes: array<object<)</code></dt>

+      <dd>This event is fired before a change is applied, and its

+      The <code>changeObj</code> object
+      has <code>from</code>, <code>to</code>, and <code>text</code>
+      properties, as with
+      the <a href="#event_change"><code>"change"</code></a> event. It
+      also has a <code>cancel()</code> method, which can be called to
+      cancel the change, and, <strong>if</strong> the change isn't
+      coming from an undo or redo event, an <code>update(from, to,
+      text)</code> method, which may be used to modify the change.
+      Undo or redo changes can't be modified, because they hold some
+      metainformation for restoring old marked ranges that is only
+      valid for that specific change. All three arguments
+      to <code>update</code> are optional, and can be left off to
+      leave the existing value for that field
+      intact. <strong>Note:</strong> you may not do anything from
+      a <code>"beforeChange"</code> handler that would cause changes
+      to the document or its visualization. Doing so will, since this

+    <h2>Key Maps</h2>
+
+    <p>Key maps are ways to associate keys with functionality. A key map
+    is an object mapping strings that identify the keys to functions
+    that implement their functionality.</p>
+
+    <p>The CodeMirror distributions comes
+    with <a href="../demo/emacs.html">Emacs</a>, <a href="../demo/vim.html">Vim</a>,
+    and <a href="../demo/sublime.html">Sublime Text</a>-style keymaps.</p>
+
+    <p>Keys are identified either by name or by character.
+    The <code>CodeMirror.keyNames</code> object defines names for
+    common keys and associates them with their key codes. Examples of
+    names defined here are <code>Enter</code>, <code>F5</code>,
+    and <code>Q</code>. These can be prefixed
+    with <code>Shift-</code>, <code>Cmd-</code>, <code>Ctrl-</code>,
+    and <code>Alt-</code> (in that order!) to specify a modifier. So
+    for example, <code>Shift-Ctrl-Space</code> would be a valid key
+    identifier.</p>
+
+    <p>Common example: map the Tab key to insert spaces instead of a tab
+    character.</p>
+
+    <pre data-lang="javascript">
+{
+  Tab: function(cm) {
+    var spaces = Array(cm.getOption("indentUnit") + 1).join(" ");
+    cm.replaceSelection(spaces);
+  }
+}</pre>
+
+    <p>Alternatively, a character can be specified directly by
+    surrounding it in single quotes, for example <code>'$'</code>
+    or <code>'q'</code>. Due to limitations in the way browsers fire
+    key events, these may not be prefixed with modifiers.</p>
+
+    <p>The <code>CodeMirror.keyMap</code> object associates key maps
+    with names. User code and key map definitions can assign extra
+    properties to this object. Anywhere where a key map is expected, a
+    string can be given, which will be looked up in this object. It
+    also contains the <code>"default"</code> key map holding the
+    default bindings.</p>
+
+    <p>The values of properties in key maps can be either functions of
+    a single argument (the CodeMirror instance), strings, or
+    <code>false</code>. Strings refer
+    to <a href="#commands">commands</a>, which are described below. If
+    the property is set to <code>false</code>, CodeMirror leaves
+    handling of the key up to the browser. A key handler function may
+    return <code>CodeMirror.Pass</code> to indicate that it has
+    decided not to handle the key, and other handlers (or the default
+    behavior) should be given a turn.</p>
+
+    <p>Keys mapped to command names that start with the
+    characters <code>"go"</code> (which should be used for
+    cursor-movement actions) will be fired even when an
+    extra <code>Shift</code> modifier is present (i.e. <code>"Up":
+    "goLineUp"</code> matches both up and shift-up). This is used to
+    easily implement shift-selection.</p>
+
+    <p>Key maps can defer to each other by defining
+    a <code>fallthrough</code> property. This indicates that when a
+    key is not found in the map itself, one or more other maps should
+    be searched. It can hold either a single key map or an array of
+    key maps.</p>
+
+    <p>When a key map contains a <code>nofallthrough</code> property
+    set to <code>true</code>, keys matched against that map will be
+    ignored if they don't match any of the bindings in the map (no
+    further child maps will be tried). When
+    the <code>disableInput</code> property is set
+    to <code>true</code>, the default effect of inserting a character
+    will be suppressed when the key map is active as the top-level
+    map.</p>

+
+<section id=commands>
+    <h2>Commands</h2>
+
+    <p>Commands are parameter-less actions that can be performed on an
+    editor. Their main use is for key bindings. Commands are defined by
+    adding properties to the <code>CodeMirror.commands</code> object.
+    A number of common commands are defined by the library itself,
+    most of them used by the default key bindings. The value of a
+    command property must be a function of one argument (an editor
+    instance).</p>
+
+    <p>Some of the commands below are referenced in the default
+    key map, but not defined by the core library. These are intended to
+    be defined by user code or addons.</p>
+
+    <p>Commands can also be run with
+    the <a href="#execCommand"><code>execCommand</code></a>
+    method.</p>

+    <h2>Customized Styling</h2>
+
+    <p>Up to a certain extent, CodeMirror's look can be changed by
+    modifying style sheet files. The style sheets supplied by modes
+    simply provide the colors for that mode, and can be adapted in a
+    very straightforward way. To style the editor itself, it is
+    possible to alter or override the styles defined
+    in <a href="../lib/codemirror.css"><code>codemirror.css</code></a>.</p>
+
+    <p>Some care must be taken there, since a lot of the rules in this
+    file are necessary to have CodeMirror function properly. Adjusting
+    colors should be safe, of course, and with some care a lot of
+    other things can be changed as well. The CSS classes defined in
+    this file serve the following roles:</p>
+
+    <dl>
+      <dt id="class_CodeMirror"><code><strong>CodeMirror</strong></code></dt>
+      <dd>The outer element of the editor. This should be used for the
+      editor width, height, borders and positioning. Can also be used
+      to set styles that should hold for everything inside the editor
+      (such as font and font size), or to set a background.</dd>
+
+      <dt id="class_CodeMirror_scroll"><code><strong>CodeMirror-scroll</strong></code></dt>
+      <dd>Whether the editor scrolls (<code>overflow: auto</code> +
+      fixed height). By default, it does. Setting
+      the <code>CodeMirror</code> class to have <code>height:
+      auto</code> and giving this class <code>overflow-x: auto;
+      overflow-y: hidden;</code> will cause the editor
+      to <a href="../demo/resize.html">resize to fit its
+      content</a>.</dd>
+
+      <dt id="class_CodeMirror_focused"><code><strong>CodeMirror-focused</strong></code></dt>
+      <dd>Whenever the editor is focused, the top element gets this
+      class. This is used to hide the cursor and give the selection a
+      different color when the editor is not focused.</dd>
+
+      <dt id="class_CodeMirror_gutters"><code><strong>CodeMirror-gutters</strong></code></dt>
+      <dd>This is the backdrop for all gutters. Use it to set the
+      default gutter background color, and optionally add a border on
+      the right of the gutters.</dd>
+
+      <dt id="class_CodeMirror_linenumbers"><code><strong>CodeMirror-linenumbers</strong></code></dt>
+      <dd>Use this for giving a background or width to the line number
+      gutter.</dd>
+
+      <dt id="class_CodeMirror_linenumber"><code><strong>CodeMirror-linenumber</strong></code></dt>
+      <dd>Used to style the actual individual line numbers. These
+      won't be children of the <code>CodeMirror-linenumbers</code>
+      (plural) element, but rather will be absolutely positioned to
+      overlay it. Use this to set alignment and text properties for
+      the line numbers.</dd>
+
+      <dt id="class_CodeMirror_lines"><code><strong>CodeMirror-lines</strong></code></dt>
+      <dd>The visible lines. This is where you specify vertical
+      padding for the editor content.</dd>
+
+      <dt id="class_CodeMirror_cursor"><code><strong>CodeMirror-cursor</strong></code></dt>
+      <dd>The cursor is a block element that is absolutely positioned.
+      You can make it look whichever way you want.</dd>
+
+      <dt id="class_CodeMirror_selected"><code><strong>CodeMirror-selected</strong></code></dt>
+      <dd>The selection is represented by <code>span</code> elements
+      with this class.</dd>
+
+      <dt id="class_CodeMirror_matchingbracket"><code><strong>CodeMirror-matchingbracket</strong></code>,
+        <code><strong>CodeMirror-nonmatchingbracket</strong></code></dt>
+      <dd>These are used to style matched (or unmatched) brackets.</dd>
+    </dl>
+
+    <p>If your page's style sheets do funky things to
+    all <code>div</code> or <code>pre</code> elements (you probably
+    shouldn't do that), you'll have to define rules to cancel these
+    effects out again for elements under the <code>CodeMirror</code>
+    class.</p>
+
+    <p>Themes are also simply CSS files, which define colors for
+    various syntactic elements. See the files in
+    the <a href="../theme/"><code>theme</code></a> directory.</p>
+</section>
+
+<section id=api>
+    <h2>Programming API</h2>
+
+    <p>A lot of CodeMirror features are only available through its
+    API. Thus, you need to write code (or
+    use <a href="#addons">addons</a>) if you want to expose them to
+    your users.</p>
+
+    <p>Whenever points in the document are represented, the API uses
+    objects with <code>line</code> and <code>ch</code> properties.
+    Both are zero-based. CodeMirror makes sure to 'clip' any positions
+    passed by client code so that they fit inside the document, so you
+    shouldn't worry too much about sanitizing your coordinates. If you
+    give <code>ch</code> a value of <code>null</code>, or don't
+    specify it, it will be replaced with the length of the specified
+    line.</p>
+
+    <p>Methods prefixed with <code>doc.</code> can, unless otherwise
+    specified, be called both on <code>CodeMirror</code> (editor)
+    instances and <code>CodeMirror.Doc</code> instances. Methods
+    prefixed with <code>cm.</code> are <em>only</em> available
+    on <code>CodeMirror</code> instances.</p>
+
+    <h3 id="api_constructor">Constructor</h3>
+
+    <p id="CodeMirror">Constructing an editor instance is done with
+    the <code><strong>CodeMirror</strong>(place: Element|fn(Element),
+    ?option: object)</code> constructor. If the <code>place</code>
+    argument is a DOM element, the editor will be appended to it. If
+    it is a function, it will be called, and is expected to place the
+    editor into the document. <code>options</code> may be an element
+    mapping <a href="#config">option names</a> to values. The options
+    that it doesn't explicitly specify (or all options, if it is not
+    passed) will be taken
+    from <a href="#defaults"><code>CodeMirror.defaults</code></a>.</p>
+
+    <p>Note that the options object passed to the constructor will be

+      <dd>Provides a very simple way to query users for text input.
+      Adds an <strong><code>openDialog</code></strong> method to
+      CodeMirror instances, which can be called with an HTML fragment
+      or a detached DOM node that provides the prompt (should include
+      an <code>input</code> tag), and a callback function that is called
+      when text has been entered. Also adds

+      <dd>Adds the <code>getSearchCursor(query, start, caseFold) →
+      cursor</code> method to CodeMirror instances, which can be used
+      to implement search/replace functionality. <code>query</code>
+      can be a regular expression or a string (only strings will match
+      across lines—if they contain newlines). <code>start</code>
+      provides the starting position of the search. It can be

+    <h2>Writing CodeMirror Modes</h2>
+
+    <p>Modes typically consist of a single JavaScript file. This file
+    defines, in the simplest case, a lexer (tokenizer) for your
+    language—a function that takes a character stream as input,
+    advances it past a token, and returns a style for that token. More
+    advanced modes can also handle indentation for the language.</p>
+
+    <p id="defineMode">The mode script should
+    call <code><strong>CodeMirror.defineMode</strong></code> to
+    register itself with CodeMirror. This function takes two
+    arguments. The first should be the name of the mode, for which you
+    should use a lowercase string, preferably one that is also the
+    name of the files that define the mode (i.e. <code>"xml"</code> is
+    defined in <code>xml.js</code>). The second argument should be a
+    function that, given a CodeMirror configuration object (the thing
+    passed to the <code>CodeMirror</code> function) and an optional
+    mode configuration object (as in
+    the <a href="#option_mode"><code>mode</code></a> option), returns
+    a mode object.</p>
+
+    <p>Typically, you should use this second argument
+    to <code>defineMode</code> as your module scope function (modes
+    should not leak anything into the global scope!), i.e. write your
+    whole mode inside this function.</p>
+
+    <p>The main responsibility of a mode script is <em>parsing</em>
+    the content of the editor. Depending on the language and the
+    amount of functionality desired, this can be done in really easy
+    or extremely complicated ways. Some parsers can be stateless,
+    meaning that they look at one element (<em>token</em>) of the code
+    at a time, with no memory of what came before. Most, however, will
+    need to remember something. This is done by using a <em>state
+    object</em>, which is an object that is always passed when
+    reading a token, and which can be mutated by the tokenizer.</p>
+
+    <p id="startState">Modes that use a state must define
+    a <code><strong>startState</strong></code> method on their mode
+    object. This is a function of no arguments that produces a state
+    object to be used at the start of a document.</p>
+
+    <p id="token">The most important part of a mode object is
+    its <code><strong>token</strong>(stream, state)</code> method. All
+    modes must define this method. It should read one token from the
+    stream it is given as an argument, optionally update its state,
+    and return a style string, or <code>null</code> for tokens that do
+    not have to be styled. For your styles, you are encouraged to use
+    the 'standard' names defined in the themes (without
+    the <code>cm-</code> prefix). If that fails, it is also possible
+    to come up with your own and write your own CSS theme file.<p>
+
+    <p id="token_style_line">A typical token string would
+    be <code>"variable"</code> or <code>"comment"</code>. Multiple
+    styles can be returned (separated by spaces), for
+    example <code>"string error"</code> for a thing that looks like a
+    string but is invalid somehow (say, missing its closing quote).
+    When a style is prefixed by <code>"line-"</code>
+    or <code>"line-background-"</code>, the style will be applied to
+    the whole line, analogous to what
+    the <a href="#addLineClass"><code>addLineClass</code></a> method
+    does—styling the <code>"text"</code> in the simple case, and
+    the <code>"background"</code> element
+    when <code>"line-background-"</code> is prefixed.</p>
+
+    <p id="StringStream">The stream object that's passed
+    to <code>token</code> encapsulates a line of code (tokens may
+    never span lines) and our current position in that line. It has
+    the following API:</p>
+
+    <dl>
+      <dt><code><strong>eol</strong>() → boolean</code></dt>
+      <dd>Returns true only if the stream is at the end of the
+      line.</dd>
+      <dt><code><strong>sol</strong>() → boolean</code></dt>
+      <dd>Returns true only if the stream is at the start of the
+      line.</dd>
+
+      <dt><code><strong>peek</strong>() → string</code></dt>
+      <dd>Returns the next character in the stream without advancing
+      it. Will return an <code>null</code> at the end of the
+      line.</dd>
+      <dt><code><strong>next</strong>() → string</code></dt>
+      <dd>Returns the next character in the stream and advances it.
+      Also returns <code>null</code> when no more characters are
+      available.</dd>
+
+      <dt><code><strong>eat</strong>(match: string|regexp|function(char: string) → boolean) → string</code></dt>
+      <dd><code>match</code> can be a character, a regular expression,
+      or a function that takes a character and returns a boolean. If
+      the next character in the stream 'matches' the given argument,
+      it is consumed and returned. Otherwise, <code>undefined</code>
+      is returned.</dd>
+      <dt><code><strong>eatWhile</strong>(match: string|regexp|function(char: string) → boolean) → boolean</code></dt>
+      <dd>Repeatedly calls <code>eat</code> with the given argument,
+      until it fails. Returns true if any characters were eaten.</dd>
+      <dt><code><strong>eatSpace</strong>() → boolean</code></dt>
+      <dd>Shortcut for <code>eatWhile</code> when matching
+      white-space.</dd>
+      <dt><code><strong>skipToEnd</strong>()</code></dt>
+      <dd>Moves the position to the end of the line.</dd>
+      <dt><code><strong>skipTo</strong>(ch: string) → boolean</code></dt>
+      <dd>Skips to the next occurrence of the given character, if
+      found on the current line (doesn't advance the stream if the
+      character does not occur on the line). Returns true if the
+      character was found.</dd>
+      <dt><code><strong>match</strong>(pattern: string, ?consume: boolean, ?caseFold: boolean) → boolean</code></dt>
+      <dt><code><strong>match</strong>(pattern: regexp, ?consume: boolean) → array<string></code></dt>
+      <dd>Act like a
+      multi-character <code>eat</code>—if <code>consume</code> is true
+      or not given—or a look-ahead that doesn't update the stream
+      position—if it is false. <code>pattern</code> can be either a
+      string or a regular expression starting with <code>^</code>.
+      When it is a string, <code>caseFold</code> can be set to true to
+      make the match case-insensitive. When successfully matching a
+      regular expression, the returned value will be the array
+      returned by <code>match</code>, in case you need to extract
+      matched groups.</dd>
+
+      <dt><code><strong>backUp</strong>(n: integer)</code></dt>
+      <dd>Backs up the stream <code>n</code> characters. Backing it up
+      further than the start of the current token will cause things to
+      break, so be careful.</dd>
+      <dt><code><strong>column</strong>() → integer</code></dt>
+      <dd>Returns the column (taking into account tabs) at which the
+      current token starts.</dd>
+      <dt><code><strong>indentation</strong>() → integer</code></dt>
+      <dd>Tells you how far the current line has been indented, in
+      spaces. Corrects for tab characters.</dd>
+
+      <dt><code><strong>current</strong>() → string</code></dt>
+      <dd>Get the string between the start of the current token and
+      the current stream position.</dd>
+    </dl>
+
+    <p id="blankLine">By default, blank lines are simply skipped when
+    tokenizing a document. For languages that have significant blank
+    lines, you can define
+    a <code><strong>blankLine</strong>(state)</code> method on your
+    mode that will get called whenever a blank line is passed over, so
+    that it can update the parser state.</p>
+
+    <p id="copyState">Because state object are mutated, and CodeMirror
+    needs to keep valid versions of a state around so that it can
+    restart a parse at any line, copies must be made of state objects.
+    The default algorithm used is that a new state object is created,
+    which gets all the properties of the old object. Any properties
+    which hold arrays get a copy of these arrays (since arrays tend to
+    be used as mutable stacks). When this is not correct, for example
+    because a mode mutates non-array properties of its state object, a
+    mode object should define
+    a <code><strong>copyState</strong></code> method, which is given a
+    state and should return a safe copy of that state.</p>
+
+    <p id="indent">If you want your mode to provide smart indentation
+    (through the <a href="#indentLine"><code>indentLine</code></a>
+    method and the <code>indentAuto</code>
+    and <code>newlineAndIndent</code> commands, to which keys can be
+    <a href="#option_extraKeys">bound</a>), you must define
+    an <code><strong>indent</strong>(state, textAfter)</code> method
+    on your mode object.</p>
+
+    <p>The indentation method should inspect the given state object,
+    and optionally the <code>textAfter</code> string, which contains
+    the text on the line that is being indented, and return an
+    integer, the amount of spaces to indent. It should usually take
+    the <a href="#option_indentUnit"><code>indentUnit</code></a>
+    option into account. An indentation method may
+    return <code>CodeMirror.Pass</code> to indicate that it
+    could not come up with a precise indentation.</p>
+
+    <p id="mode_comment">To work well with
+    the <a href="#addon_comment">commenting addon</a>, a mode may
+    define <code><strong>lineComment</strong></code> (string that
+    starts a line
+    comment), <code><strong>blockCommentStart</strong></code>, <code><strong>blockCommentEnd</strong></code>
+    (strings that start and end block comments),
+    and <code>blockCommentLead</code> (a string to put at the start of
+    continued lines in a block comment). All of these are
+    optional.</p>
+
+    <p id="electricChars">Finally, a mode may define
+    an <code>electricChars</code> property, which should hold a string
+    containing all the characters that should trigger the behaviour
+    described for
+    the <a href="#option_electricChars"><code>electricChars</code></a>
+    option.</p>
+
+    <p>So, to summarize, a mode <em>must</em> provide
+    a <code>token</code> method, and it <em>may</em>
+    provide <code>startState</code>, <code>copyState</code>,
+    and <code>indent</code> methods. For an example of a trivial mode,
+    see the <a href="../mode/diff/diff.js">diff mode</a>, for a more
+    involved example, see the <a href="../mode/clike/clike.js">C-like
+    mode</a>.</p>
+
+    <p>Sometimes, it is useful for modes to <em>nest</em>—to have one
+    mode delegate work to another mode. An example of this kind of
+    mode is the <a href="../mode/htmlmixed/htmlmixed.js">mixed-mode HTML
+    mode</a>. To implement such nesting, it is usually necessary to
+    create mode objects and copy states yourself. To create a mode
+    object, there are <code>CodeMirror.getMode(options,
+    parserConfig)</code>, where the first argument is a configuration
+    object as passed to the mode constructor function, and the second
+    argument is a mode specification as in
+    the <a href="#option_mode"><code>mode</code></a> option. To copy a
+    state object, call <code>CodeMirror.copyState(mode, state)</code>,
+    where <code>mode</code> is the mode that created the given
+    state.</p>
+
+    <p id="innerMode">In a nested mode, it is recommended to add an
+    extra method, <code><strong>innerMode</strong></code> which, given
+    a state object, returns a <code>{state, mode}</code> object with
+    the inner mode and its state for the current position. These are
+    used by utility scripts such as the <a href="#addon_closetag">tag
+    closer</a> to get context information. Use
+    the <code>CodeMirror.innerMode</code> helper function to, starting
+    from a mode and a state, recursively walk down to the innermost
+    mode and state.</p>
+
+    <p>To make indentation work properly in a nested parser, it is
+    advisable to give the <code>startState</code> method of modes that
+    are intended to be nested an optional argument that provides the
+    base indentation for the block of code. The JavaScript and CSS
+    parser do this, for example, to allow JavaScript and CSS code
+    inside the mixed-mode HTML mode to be properly indented.</p>
+
+    <p id="defineMIME">It is possible, and encouraged, to associate
+    your mode, or a certain configuration of your mode, with
+    a <a href="http://en.wikipedia.org/wiki/MIME">MIME</a> type. For
+    example, the JavaScript mode associates itself
+    with <code>text/javascript</code>, and its JSON variant
+    with <code>application/json</code>. To do this,
+    call <code><strong>CodeMirror.defineMIME</strong>(mime,
+    modeSpec)</code>, where <code>modeSpec</code> can be a string or
+    object specifying a mode, as in
+    the <a href="#option_mode"><code>mode</code></a> option.</p>
+
+    <p>If a mode specification wants to add some properties to the
+    resulting mode object, typically for use
+    with <a href="#getHelpers"><code>getHelpers</code></a>, it may
+    contain a <code>modeProps</code> property, which holds an object.
+    This object's properties will be copied to the actual mode
+    object.</p>
+
+    <p id="extendMode">Sometimes, it is useful to add or override mode
+    object properties from external code.
+    The <code><strong>CodeMirror.extendMode</strong></code> function
+    can be used to add properties to mode objects produced for a
+    specific mode. Its first argument is the name of the mode, its
+    second an object that specifies the properties that should be
+    added. This is mostly useful to add utilities that can later be
+    looked up through <a href="#getMode"><code>getMode</code></a>.</p>

+<h2>Reporting bugs effectively</h2>
+
+<div class="left">
+
+<p>So you found a problem in CodeMirror. By all means, report it! Bug
+reports from users are the main drive behind improvements to
+CodeMirror. But first, please read over these points:</p>
+
+<ol>
+  <li>CodeMirror is maintained by volunteers. They don't owe you
+  anything, so be polite. Reports with an indignant or belligerent
+  tone tend to be moved to the bottom of the pile.</li>
+
+  <li>Include information about <strong>the browser in which the
+  problem occurred</strong>. Even if you tested several browsers, and
+  the problem occurred in all of them, mention this fact in the bug
+  report. Also include browser version numbers and the operating
+  system that you're on.</li>
+
+  <li>Mention which release of CodeMirror you're using. Preferably,
+  try also with the current development snapshot, to ensure the
+  problem has not already been fixed.</li>
+
+  <li>Mention very precisely what went wrong. "X is broken" is not a
+  good bug report. What did you expect to happen? What happened
+  instead? Describe the exact steps a maintainer has to take to make
+  the problem occur. We can not fix something that we can not
+  observe.</li>
+
+  <li>If the problem can not be reproduced in any of the demos
+  included in the CodeMirror distribution, please provide an HTML
+  document that demonstrates the problem. The best way to do this is
+  to go to <a href="http://jsbin.com/ihunin/edit">jsbin.com</a>, enter
+  it there, press save, and include the resulting link in your bug
+  report.</li>

+<article>
+
+<h2>Upgrading to v2.2</h2>
+
+<p>There are a few things in the 2.2 release that require some care
+when upgrading.</p>
+
+<h3>No more default.css</h3>
+
+<p>The default theme is now included
+in <a href="../lib/codemirror.css"><code>codemirror.css</code></a>, so
+you do not have to included it separately anymore. (It was tiny, so
+even if you're not using it, the extra data overhead is negligible.)
+
+<h3>Different key customization</h3>
+
+<p>CodeMirror has moved to a system
+where <a href="manual.html#option_keyMap">keymaps</a> are used to
+bind behavior to keys. This means <a href="../demo/emacs.html">custom
+bindings</a> are now possible.</p>
+
+<p>Three options that influenced key
+behavior, <code>tabMode</code>, <code>enterMode</code>,
+and <code>smartHome</code>, are no longer supported. Instead, you can
+provide custom bindings to influence the way these keys act. This is
+done through the
+new <a href="manual.html#option_extraKeys"><code>extraKeys</code></a>
+option, which can hold an object mapping key names to functionality. A
+simple example would be:</p>
+
+<pre>  extraKeys: {
+    "Ctrl-S": function(instance) { saveText(instance.getValue()); },
+    "Ctrl-/": "undo"
+  }</pre>
+
+<p>Keys can be mapped either to functions, which will be given the
+editor instance as argument, or to strings, which are mapped through
+functions through the <code>CodeMirror.commands</code> table, which
+contains all the built-in editing commands, and can be inspected and
+extended by external code.</p>
+
+<p>By default, the <code>Home</code> key is bound to
+the <code>"goLineStartSmart"</code> command, which moves the cursor to
+the first non-whitespace character on the line. You can set do this to
+make it always go to the very start instead:</p>
+
+<pre>  extraKeys: {"Home": "goLineStart"}</pre>
+
+<p>Similarly, <code>Enter</code> is bound
+to <code>"newlineAndIndent"</code> by default. You can bind it to
+something else to get different behavior. To disable special handling
+completely and only get a newline character inserted, you can bind it
+to <code>false</code>:</p>
+
+<pre>  extraKeys: {"Enter": false}</pre>
+
+<p>The same works for <code>Tab</code>. If you don't want CodeMirror
+to handle it, bind it to <code>false</code>. The default behaviour is
+to indent the current line more (<code>"indentMore"</code> command),
+and indent it less when shift is held (<code>"indentLess"</code>).
+There are also <code>"indentAuto"</code> (smart indent)
+and <code>"insertTab"</code> commands provided for alternate
+behaviors. Or you can write your own handler function to do something
+different altogether.</p>
+
+<h3>Tabs</h3>
+
+<p>Handling of tabs changed completely. The display width of tabs can
+now be set with the <code>tabSize</code> option, and tabs can
+be <a href="../demo/visibletabs.html">styled</a> by setting CSS rules
+for the <code>cm-tab</code> class.</p>
+
+<p>The default width for tabs is now 4, as opposed to the 8 that is
+hard-wired into browsers. If you are relying on 8-space tabs, make
+sure you explicitly set <code>tabSize: 8</code> in your options.</p>

+
+<h2 id=upgrade>Upgrading to version 3</h2>
+
+<p>Version 3 does not depart too much from 2.x API, and sites that use
+CodeMirror in a very simple way might be able to upgrade without
+trouble. But it does introduce a number of incompatibilities. Please
+at least skim this text before upgrading.</p>
+
+<p>Note that <strong>version 3 drops full support for Internet
+Explorer 7</strong>. The editor will mostly work on that browser, but
+it'll be significantly glitchy.</p>
+
+<section id=dom>
+  <h2>DOM structure</h2>
+
+<p>This one is the most likely to cause problems. The internal
+structure of the editor has changed quite a lot, mostly to implement a
+new scrolling model.</p>
+
+<p>Editor height is now set on the outer wrapper element (CSS
+class <code>CodeMirror</code>), not on the scroller element
+(<code>CodeMirror-scroll</code>).</p>
+
+<p>Other nodes were moved, dropped, and added. If you have any code
+that makes assumptions about the internal DOM structure of the editor,
+you'll have to re-test it and probably update it to work with v3.</p>
+
+<p>See the <a href="manual.html#styling">styling section</a> of the
+manual for more information.</p>
+</section>
+<section id=gutters>
+  <h2>Gutter model</h2>
+
+<p>In CodeMirror 2.x, there was a single gutter, and line markers
+created with <code>setMarker</code> would have to somehow coexist with
+the line numbers (if present). Version 3 allows you to specify an
+array of gutters, <a href="manual.html#option_gutters">by class
+name</a>,
+use <a href="manual.html#setGutterMarker"><code>setGutterMarker</code></a>
+to add or remove markers in individual gutters, and clear whole
+gutters
+with <a href="manual.html#clearGutter"><code>clearGutter</code></a>.
+Gutter markers are now specified as DOM nodes, rather than HTML
+snippets.</p>
+
+<p>The gutters no longer horizontally scrolls along with the content.
+The <code>fixedGutter</code> option was removed (since it is now the
+only behavior).</p>
+
+<pre data-lang="text/html">
+<style>
+  /* Define a gutter style */
+  .note-gutter { width: 3em; background: cyan; }
+</style>
+<script>
+  // Create an instance with two gutters -- line numbers and notes
+  var cm = new CodeMirror(document.body, {
+    gutters: ["note-gutter", "CodeMirror-linenumbers"],
+    lineNumbers: true
+  });
+  // Add a note to line 0
+  cm.setGutterMarker(0, "note-gutter", document.createTextNode("hi"));
+</script>
+</pre>
+</section>
+<section id=events>
+  <h2>Event handling</h2>
+
+<p>Most of the <code>onXYZ</code> options have been removed. The same
+effect is now obtained by calling
+the <a href="manual.html#on"><code>on</code></a> method with a string
+identifying the event type. Multiple handlers can now be registered
+(and individually unregistered) for an event, and objects such as line
+handlers now also expose events. See <a href="manual.html#events">the
+full list here</a>.</p>
+
+<p>(The <code>onKeyEvent</code> and <code>onDragEvent</code> options,
+which act more as hooks than as event handlers, are still there in
+their old form.)</p>
+
+<pre data-lang="javascript">
+cm.on("change", function(cm, change) {
+  console.log("something changed! (" + change.origin + ")");
+});
+</pre>
+</section>
+<section id=marktext>
+  <h2>markText method arguments</h2>
+
+<p>The <a href="manual.html#markText"><code>markText</code></a> method
+(which has gained some interesting new features, such as creating
+atomic and read-only spans, or replacing spans with widgets) no longer
+takes the CSS class name as a separate argument, but makes it an
+optional field in the options object instead.</p>
+
+<pre data-lang="javascript">
+// Style first ten lines, and forbid the cursor from entering them
+cm.markText({line: 0, ch: 0}, {line: 10, ch: 0}, {
+  className: "magic-text",
+  inclusiveLeft: true,
+  atomic: true
+});
+</pre>
+</section>
+<section id=folding>
+  <h2>Line folding</h2>
+
+<p>The interface for hiding lines has been
+removed. <a href="manual.html#markText"><code>markText</code></a> can
+now be used to do the same in a more flexible and powerful way.</p>
+
+<p>The <a href="../demo/folding.html">folding script</a> has been
+updated to use the new interface, and should now be more robust.</p>
+
+<pre data-lang="javascript">
+// Fold a range, replacing it with the text "??"
+var range = cm.markText({line: 4, ch: 2}, {line: 8, ch: 1}, {
+  replacedWith: document.createTextNode("??"),
+  // Auto-unfold when cursor moves into the range
+  clearOnEnter: true
+});
+// Get notified when auto-unfolding
+CodeMirror.on(range, "clear", function() {
+  console.log("boom");
+});
+</pre>
+</section>
+<section id=lineclass>
+  <h2>Line CSS classes</h2>
+
+<p>The <code>setLineClass</code> method has been replaced
+by <a href="manual.html#addLineClass"><code>addLineClass</code></a>
+and <a href="manual.html#removeLineClass"><code>removeLineClass</code></a>,
+which allow more modular control over the classes attached to a line.</p>
+
+<pre data-lang="javascript">
+var marked = cm.addLineClass(10, "background", "highlighted-line");
+setTimeout(function() {
+  cm.removeLineClass(marked, "background", "highlighted-line");
+});
+</pre>
+</section>
+<section id=positions>
+  <h2>Position properties</h2>
+
+<p>All methods that take or return objects that represent screen
+positions now use <code>{left, top, bottom, right}</code> properties
+(not always all of them) instead of the <code>{x, y, yBot}</code> used
+by some methods in v2.x.</p>
+
+<p>Affected methods
+are <a href="manual.html#cursorCoords"><code>cursorCoords</code></a>, <a href="manual.html#charCoords"><code>charCoords</code></a>, <a href="manual.html#coordsChar"><code>coordsChar</code></a>,
+and <a href="manual.html#getScrollInfo"><code>getScrollInfo</code></a>.</p>
+</section>
+<section id=matchbrackets>
+  <h2>Bracket matching no longer in core</h2>
+
+<p>The <a href="manual.html#addon_matchbrackets"><code>matchBrackets</code></a>
+option is no longer defined in the core editor.
+Load <code>addon/edit/matchbrackets.js</code> to enable it.</p>
+</section>
+<section id=modes>
+  <h2>Mode management</h2>
+
+<p>The <code>CodeMirror.listModes</code>
+and <code>CodeMirror.listMIMEs</code> functions, used for listing
+defined modes, are gone. You are now encouraged to simply
+inspect <code>CodeMirror.modes</code> (mapping mode names to mode
+constructors) and <code>CodeMirror.mimeModes</code> (mapping MIME
+strings to mode specs).</p>
+</section>
+<section id=new>
+  <h2>New features</h2>
+
+<p>Some more reasons to upgrade to version 3.</p>
+
+<ul>
+  <li>Bi-directional text support. CodeMirror will now mostly do the
+  right thing when editing Arabic or Hebrew text.</li>
+  <li>Arbitrary line heights. Using fonts with different heights
+  inside the editor (whether off by one pixel or fifty) is now
+  supported and handled gracefully.</li>
+  <li>In-line widgets. See <a href="../demo/widget.html">the demo</a>
+  and <a href="manual.html#addLineWidget">the docs</a>.</li>
+  <li>Defining custom options
+  with <a href="manual.html#defineOption"><code>CodeMirror.defineOption</code></a>.</li>

+
+<h2 id=upgrade>Upgrading to version 4</h2>
+
+<p><strong>Note:</strong> Version 4 hasn't been released yet. The
+information here is provisional and might still change.</p>
+
+<p>CodeMirror 4's interface is <em>very</em> close version 3, but it
+does fix a few awkward details in a backwards-incompatible ways. At
+least skim the text below before upgrading.</p>
+
+<section id=multisel><h2>Multiple selections</h2>
+
+<p>The main new feature in version 4 is multiple selections. The
+single-selection variants of methods are still there, but now
+typically act only on the <em>primary</em> selection (usually the last
+one added).</p>
+
+<p>The exception to this
+is <a href="manual.html#getSelection"><strong><code>getSelection</code></strong></a>,
+which will now return the content of <em>all</em> selections
+(separated by newlines, or whatever <code>lineSep</code> parameter you passed
+it).</p>
+
+</section>
+
+<section id=beforeSelectionChange><h2>The beforeSelectionChange event</h2>
+
+<p>This event still exists, but the object it is passed has
+a <a href="manual.html#event_beforeSelectionChange">completely new
+interface</a>, because such changes now concern multiple
+selections.</p>
+
+</section>
+
+<section id=replaceSelection><h2>replaceSelection's collapsing behavior</h2>
+
+<p>By
+default, <a href="manual.html#replaceSelection"><code>replaceSelection</code></a>
+would leave the newly inserted text selected. This is only rarely what
+you want, and also (slightly) more expensive in the new model, so the
+default was changed to <code>"end"</code>, meaning the old behavior
+must be explicitly specified by passing a second argument
+of <code>"around"</code>.</p>
+
+</section>
+
+<section id=changeEvent><h2>change event data</h2>
+
+<p>Rather than forcing client code to follow <code>next</code>
+pointers from one change object to the next, the library will now
+simply fire
+multiple <a href="manual.html#event_change"><code>"change"</code></a>
+events. Existing code will probably continue to work unmodified.</p>
+
+</section>
+
+<section id=showIfHidden><h2>showIfHidden option to line widgets</h2>
+
+<p>This option, which conceptually caused line widgets to be visible
+even if their line was hidden, was never really well-defined, and was
+buggy from the start. It would be a rather expensive feature, both in
+code complexity and run-time performance, to implement properly. It
+has been dropped entirely in 4.0.</p>
+
+</section>
+
+<section id=module><h2>Module loaders</h2>
+
+<p>All modules in the CodeMirror distribution are now wrapped in a
+shim function to make them compatible with both AMD
+(<a href="http://requirejs.org">requirejs</a>) and CommonJS (as used
+by <a href="http://nodejs.org/">node</a>
+and <a href="http://browserify.org/">browserify</a>) module loaders.
+When neither of these is present, they fall back to simply using the
+global <code>CodeMirror</code> variable.</p>
+
+<p>If you have a module loader present in your environment, CodeMirror
+will attempt to use it, and you might need to change the way you load
+CodeMirror modules.</p>
+
+</section>
+
+<section id=shareddata><h2>Mutating shared data structures</h2>
+
+<p>Data structures produced by the library should not be mutated
+unless explicitly allowed, in general. This is slightly more strict in
+4.0 than it was in earlier versions, which copied the position objects
+returned by <a href="manual.html#getCursor"><code>getCursor</code></a>
+for nebulous, historic reasons. In 4.0, mutating these
+objects <em>will</em> corrupt your editor's selection.</p>
+
+</section>
+
+<section id=deprecated><h2>Deprecated interfaces dropped</h2>
+
+<p>A few properties and methods that have been deprecated for a while
+are now gone. Most notably, the <code>onKeyEvent</code>
+and <code>onDragEvent</code> options (use the
+corresponding <a href="manual.html#event_dom">events</a> instead).</p>
+
+<p>Two silly methods, which were mostly there to stay close to the 0.x
+API, <code>setLine</code> and <code>removeLine</code> are now gone.
+Use the more
+flexible <a href="manual.html#replaceRange"><code>replaceRange</code></a>
+method instead.</p>
+
+<p>The long names for folding and completing functions
+(<code>CodeMirror.braceRangeFinder</code>, <code>CodeMirror.javascriptHint</code>,
+etc) are also gone
+(use <code>CodeMirror.fold.brace</code>, <code>CodeMirror.hint.javascript</code>).</p>
+
+<p>The <code>className</code> property in the return value
+of <a href="manual.html#getTokenAt"><code>getTokenAt</code></a>, which
+has been superseded by the <code>type</code> property, is also no
+longer present.</p>

+   *  Collection classes mixing in this trait provide a concrete 
+   *  `foreach` method which traverses all the
+   *  elements contained in the collection, applying a given function to each.
+   *  They also need to provide a method `newBuilder`
+   *  which creates a builder for collections of the same kind.
+   *  
+   *  A traversable class might or might not have two properties: strictness
+   *  and orderedness. Neither is represented as a type.
+   *  
+   *  The instances of a strict collection class have all their elements
+   *  computed before they can be used as values. By contrast, instances of
+   *  a non-strict collection class may defer computation of some of their
+   *  elements until after the instance is available as a value.
+   *  A typical example of a non-strict collection class is a
+   *  <a href="../immutable/Stream.html" target="ContentFrame">
+   *  `scala.collection.immutable.Stream`</a>.
+   *  A more general class of examples are `TraversableViews`.
+   *  
+   *  If a collection is an instance of an ordered collection class, traversing
+   *  its elements with `foreach` will always visit elements in the
+   *  same order, even for different runs of the program. If the class is not
+   *  ordered, `foreach` can visit elements in different orders for
+   *  different runs (but it will keep the same order in the same run).'
+   * 
+   *  A typical example of a collection class which is not ordered is a
+   *  `HashMap` of objects. The traversal order for hash maps will
+   *  depend on the hash codes of its elements, and these hash codes might
+   *  differ from one run to the next. By contrast, a `LinkedHashMap`
+   *  is ordered because it's `foreach` method visits elements in the
+   *  order they were inserted into the `HashMap`.

+
+Getting the Gist of Markdown's Formatting Syntax
+------------------------------------------------
+
+This page offers a brief overview of what it's like to use Markdown.
+The [syntax page] [s] provides complete, detailed documentation for
+every feature, but Markdown should be very easy to pick up simply by
+looking at a few examples of it in action. The examples on this page
+are written in a before/after style, showing example syntax and the
+HTML output produced by Markdown.
+
+It's also helpful to simply try Markdown out; the [Dingus] [d] is a
+web application that allows you type your own Markdown-formatted text
+and translate it to XHTML.
+
+**Note:** This document is itself written using Markdown; you
+can [see the source for it by adding '.text' to the URL] [src].

+
+## Paragraphs, Headers, Blockquotes ##
+
+A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like
+a blank line -- a line containing nothing but spaces or tabs is
+considered blank.) Normal paragraphs should not be indented with
+spaces or tabs.
+
+Markdown offers two styles of headers: *Setext* and *atx*.
+Setext-style headers for `<h1>` and `<h2>` are created by
+"underlining" with equal signs (`=`) and hyphens (`-`), respectively.
+To create an atx-style header, you put 1-6 hash marks (`#`) at the
+beginning of the line -- the number of hashes equals the resulting
+HTML header level.
+
+Blockquotes are indicated using email-style '`>`' angle brackets.
+
+Markdown:
+
+    A First Level Header
+    ====================
+    
+    A Second Level Header
+    ---------------------
+
+    Now is the time for all good men to come to
+    the aid of their country. This is just a
+    regular paragraph.
+
+    The quick brown fox jumped over the lazy
+    dog's back.
+    
+    ### Header 3
+
+    > This is a blockquote.
+    > 
+    > This is the second paragraph in the blockquote.
+    >
+    > ## This is an H2 in a blockquote
+
+
+Output:
+
+    <h1>A First Level Header</h1>
+    
+    <h2>A Second Level Header</h2>
+    
+    <p>Now is the time for all good men to come to
+    the aid of their country. This is just a
+    regular paragraph.</p>
+    
+    <p>The quick brown fox jumped over the lazy
+    dog's back.</p>
+    
+    <h3>Header 3</h3>
+    
+    <blockquote>
+        <p>This is a blockquote.</p>
+        
+        <p>This is the second paragraph in the blockquote.</p>
+        
+        <h2>This is an H2 in a blockquote</h2>
+    </blockquote>
+
+
+
+### Phrase Emphasis ###
+
+Markdown uses asterisks and underscores to indicate spans of emphasis.
+
+Markdown:
+
+    Some of these words *are emphasized*.
+    Some of these words _are emphasized also_.
+    
+    Use two asterisks for **strong emphasis**.
+    Or, if you prefer, __use two underscores instead__.
+
+Output:
+
+    <p>Some of these words <em>are emphasized</em>.
+    Some of these words <em>are emphasized also</em>.</p>
+    
+    <p>Use two asterisks for <strong>strong emphasis</strong>.
+    Or, if you prefer, <strong>use two underscores instead</strong>.</p>
+   
+
+
+## Lists ##
+
+Unordered (bulleted) lists use asterisks, pluses, and hyphens (`*`,
+`+`, and `-`) as list markers. These three markers are
+interchangable; this:
+
+    *   Candy.
+    *   Gum.
+    *   Booze.
+
+this:
+
+    +   Candy.
+    +   Gum.
+    +   Booze.
+
+and this:
+
+    -   Candy.
+    -   Gum.
+    -   Booze.
+
+all produce the same output:
+
+    <ul>
+    <li>Candy.</li>
+    <li>Gum.</li>
+    <li>Booze.</li>
+    </ul>
+
+Ordered (numbered) lists use regular numbers, followed by periods, as
+list markers:
+
+    1.  Red
+    2.  Green
+    3.  Blue
+
+Output:
+
+    <ol>
+    <li>Red</li>
+    <li>Green</li>
+    <li>Blue</li>
+    </ol>
+
+If you put blank lines between items, you'll get `<p>` tags for the
+list item text. You can create multi-paragraph list items by indenting
+the paragraphs by 4 spaces or 1 tab:
+
+    *   A list item.
+    
+        With multiple paragraphs.
+
+    *   Another item in the list.
+
+Output:
+
+    <ul>
+    <li><p>A list item.</p>
+    <p>With multiple paragraphs.</p></li>
+    <li><p>Another item in the list.</p></li>
+    </ul>
+    
+
+
+### Links ###
+
+Markdown supports two styles for creating links: *inline* and
+*reference*. With both styles, you use square brackets to delimit the
+text you want to turn into a link.
+
+Inline-style links use parentheses immediately after the link text.
+For example:
+
+    This is an [example link](http://example.com/).
+
+Output:
+
+    <p>This is an <a href="http://example.com/">
+    example link</a>.</p>
+
+Optionally, you may include a title attribute in the parentheses:
+
+    This is an [example link](http://example.com/ "With a Title").
+
+Output:
+
+    <p>This is an <a href="http://example.com/" title="With a Title">
+    example link</a>.</p>
+
+Reference-style links allow you to refer to your links by names, which
+you define elsewhere in your document:
+
+    I get 10 times more traffic from [Google][1] than from
+    [Yahoo][2] or [MSN][3].
+
+    [1]: http://google.com/        "Google"
+    [2]: http://search.yahoo.com/  "Yahoo Search"
+    [3]: http://search.msn.com/    "MSN Search"
+
+Output:
+
+    <p>I get 10 times more traffic from <a href="http://google.com/"
+    title="Google">Google</a> than from <a href="http://search.yahoo.com/"
+    title="Yahoo Search">Yahoo</a> or <a href="http://search.msn.com/"
+    title="MSN Search">MSN</a>.</p>
+
+The title attribute is optional. Link names may contain letters,
+numbers and spaces, but are *not* case sensitive:
+
+    I start my morning with a cup of coffee and
+    [The New York Times][NY Times].
+
+    [ny times]: http://www.nytimes.com/
+
+Output:
+
+    <p>I start my morning with a cup of coffee and
+    <a href="http://www.nytimes.com/">The New York Times</a>.</p>
+
+
+### Images ###
+
+Image syntax is very much like link syntax.
+
+Inline (titles are optional):
+
+    ![alt text](/path/to/img.jpg "Title")
+
+Reference-style:
+
+    ![alt text][id]
+
+    [id]: /path/to/img.jpg "Title"
+
+Both of the above examples produce the same output:
+
+    <img src="/path/to/img.jpg" alt="alt text" title="Title" />
+
+
+
+### Code ###
+
+In a regular paragraph, you can create code span by wrapping text in
+backtick quotes. Any ampersands (`&`) and angle brackets (`<` or
+`>`) will automatically be translated into HTML entities. This makes
+it easy to use Markdown to write about HTML example code:
+
+    I strongly recommend against using any `<blink>` tags.
+
+    I wish SmartyPants used named entities like `&mdash;`
+    instead of decimal-encoded entites like `&#8212;`.
+
+Output:
+
+    <p>I strongly recommend against using any
+    <code>&lt;blink&gt;</code> tags.</p>
+    
+    <p>I wish SmartyPants used named entities like
+    <code>&amp;mdash;</code> instead of decimal-encoded
+    entites like <code>&amp;#8212;</code>.</p>
+
+
+To specify an entire block of pre-formatted code, indent every line of
+the block by 4 spaces or 1 tab. Just like with code spans, `&`, `<`,
+and `>` characters will be escaped automatically.
+
+Markdown:
+
+    If you want your page to validate under XHTML 1.0 Strict,
+    you've got to put paragraph tags in your blockquotes:
+
+        <blockquote>
+            <p>For example.</p>
+        </blockquote>
+
+Output:

+/ columns are: 
+/	c - column name; ci - column index; t - load type; mw - max width; 
+/	dchar - distinct characters in values; rule - rule that caught the type
+/	maybe - needs checking, _could_ be say a date, but perhaps just a float?
+/ .csv.info0[file;onlycols] - like .csv.info except that it only analyses <onlycols>
+/ example:
+/	info:.csv.info0[file;(.csv.colhdrs file)like"*price"]
+/	info:.csv.infolike[file;"*price"]
+/	show delete from info where t=" "
+/ .csv.data[file;info] - use the info from .csv.info to read the data
+/ .csv.data10[file;info] - like .csv.data but only returns the first 10 rows
+/ bulkload[file;info] - bulk loads file into table DATA (which must be already defined :: DATA:() )
+/ .csv.read[file]/read10[file] - for when you don't care about checking/tweaking the <info> before reading

+<h2>reStructuredText mode</h2>
+<form><textarea id="code" name="code">
+.. This is an excerpt from Sphinx documentation: http://sphinx.pocoo.org/_sources/rest.txt
+
+.. highlightlang:: rest
+
+.. _rst-primer:
+
+reStructuredText Primer
+=======================
+
+This section is a brief introduction to reStructuredText (reST) concepts and
+syntax, intended to provide authors with enough information to author documents
+productively.  Since reST was designed to be a simple, unobtrusive markup
+language, this will not take too long.
+
+.. seealso::
+
+   The authoritative `reStructuredText User Documentation
+   <http://docutils.sourceforge.net/rst.html>`_.  The "ref" links in this
+   document link to the description of the individual constructs in the reST
+   reference.
+
+
+Paragraphs
+----------
+
+The paragraph (:duref:`ref <paragraphs>`) is the most basic block in a reST
+document.  Paragraphs are simply chunks of text separated by one or more blank
+lines.  As in Python, indentation is significant in reST, so all lines of the
+same paragraph must be left-aligned to the same level of indentation.
+
+
+.. _inlinemarkup:
+
+Inline markup
+-------------
+
+The standard reST inline markup is quite simple: use
+
+* one asterisk: ``*text*`` for emphasis (italics),
+* two asterisks: ``**text**`` for strong emphasis (boldface), and
+* backquotes: ````text```` for code samples.
+
+If asterisks or backquotes appear in running text and could be confused with
+inline markup delimiters, they have to be escaped with a backslash.
+
+Be aware of some restrictions of this markup:
+
+* it may not be nested,
+* content may not start or end with whitespace: ``* text*`` is wrong,
+* it must be separated from surrounding text by non-word characters.  Use a
+  backslash escaped space to work around that: ``thisis\ *one*\ word``.
+
+These restrictions may be lifted in future versions of the docutils.
+
+reST also allows for custom "interpreted text roles"', which signify that the
+enclosed text should be interpreted in a specific way.  Sphinx uses this to
+provide semantic markup and cross-referencing of identifiers, as described in
+the appropriate section.  The general syntax is ``:rolename:`content```.
+
+Standard reST provides the following roles:
+
+* :durole:`emphasis` -- alternate spelling for ``*emphasis*``
+* :durole:`strong` -- alternate spelling for ``**strong**``
+* :durole:`literal` -- alternate spelling for ````literal````
+* :durole:`subscript` -- subscript text
+* :durole:`superscript` -- superscript text
+* :durole:`title-reference` -- for titles of books, periodicals, and other
+  materials
+
+See :ref:`inline-markup` for roles added by Sphinx.
+
+
+Lists and Quote-like blocks
+---------------------------
+
+List markup (:duref:`ref <bullet-lists>`) is natural: just place an asterisk at
+the start of a paragraph and indent properly.  The same goes for numbered lists;
+they can also be autonumbered using a ``#`` sign::
+
+   * This is a bulleted list.
+   * It has two items, the second
+     item uses two lines.
+
+   1. This is a numbered list.
+   2. It has two items too.
+
+   #. This is a numbered list.
+   #. It has two items too.
+
+
+Nested lists are possible, but be aware that they must be separated from the
+parent list items by blank lines::
+
+   * this is
+   * a list
+
+     * with a nested list
+     * and some subitems
+
+   * and here the parent list continues
+
+Definition lists (:duref:`ref <definition-lists>`) are created as follows::
+
+   term (up to a line of text)
+      Definition of the term, which must be indented
+
+      and can even consist of multiple paragraphs
+
+   next term
+      Description.
+
+Note that the term cannot have more than one line of text.
+
+Quoted paragraphs (:duref:`ref <block-quotes>`) are created by just indenting
+them more than the surrounding paragraphs.
+
+Line blocks (:duref:`ref <line-blocks>`) are a way of preserving line breaks::
+
+   | These lines are
+   | broken exactly like in
+   | the source file.
+
+There are also several more special blocks available:
+
+* field lists (:duref:`ref <field-lists>`)
+* option lists (:duref:`ref <option-lists>`)
+* quoted literal blocks (:duref:`ref <quoted-literal-blocks>`)
+* doctest blocks (:duref:`ref <doctest-blocks>`)
+
+
+Source Code
+-----------
+
+Literal code blocks (:duref:`ref <literal-blocks>`) are introduced by ending a
+paragraph with the special marker ``::``.  The literal block must be indented
+(and, like all paragraphs, separated from the surrounding ones by blank lines)::
+
+   This is a normal text paragraph. The next paragraph is a code sample::
+
+      It is not processed in any way, except
+      that the indentation is removed.
+
+      It can span multiple lines.
+
+   This is a normal text paragraph again.
+
+The handling of the ``::`` marker is smart:
+
+* If it occurs as a paragraph of its own, that paragraph is completely left
+  out of the document.
+* If it is preceded by whitespace, the marker is removed.
+* If it is preceded by non-whitespace, the marker is replaced by a single
+  colon.
+
+That way, the second sentence in the above example's first paragraph would be
+rendered as "The next paragraph is a code sample:".
+
+
+.. _rst-tables:
+
+Tables
+------
+
+Two forms of tables are supported.  For *grid tables* (:duref:`ref
+<grid-tables>`), you have to "paint" the cell grid yourself.  They look like
+this::
+
+   +------------------------+------------+----------+----------+
+   | Header row, column 1   | Header 2   | Header 3 | Header 4 |
+   | (header rows optional) |            |          |          |
+   +========================+============+==========+==========+
+   | body row 1, column 1   | column 2   | column 3 | column 4 |
+   +------------------------+------------+----------+----------+
+   | body row 2             | ...        | ...      |          |
+   +------------------------+------------+----------+----------+
+
+*Simple tables* (:duref:`ref <simple-tables>`) are easier to write, but
+limited: they must contain more than one row, and the first column cannot
+contain multiple lines.  They look like this::
+
+   =====  =====  =======
+   A      B      A and B
+   =====  =====  =======
+   False  False  False
+   True   False  False
+   False  True   False
+   True   True   True
+   =====  =====  =======
+
+
+Hyperlinks
+----------
+
+External links
+^^^^^^^^^^^^^^
+
+Use ```Link text <http://example.com/>`_`` for inline web links.  If the link
+text should be the web address, you don't need special markup at all, the parser
+finds links and mail addresses in ordinary text.
+
+You can also separate the link and the target definition (:duref:`ref
+<hyperlink-targets>`), like this::
+
+   This is a paragraph that contains `a link`_.
+
+   .. _a link: http://example.com/
+
+
+Internal links
+^^^^^^^^^^^^^^
+
+Internal linking is done via a special reST role provided by Sphinx, see the
+section on specific markup, :ref:`ref-role`.
+
+
+Sections
+--------
+
+Section headers (:duref:`ref <sections>`) are created by underlining (and
+optionally overlining) the section title with a punctuation character, at least
+as long as the text::
+
+   =================
+   This is a heading
+   =================
+
+Normally, there are no heading levels assigned to certain characters as the
+structure is determined from the succession of headings.  However, for the
+Python documentation, this convention is used which you may follow:
+
+* ``#`` with overline, for parts
+* ``*`` with overline, for chapters
+* ``=``, for sections
+* ``-``, for subsections
+* ``^``, for subsubsections
+* ``"``, for paragraphs
+
+Of course, you are free to use your own marker characters (see the reST
+documentation), and use a deeper nesting level, but keep in mind that most
+target formats (HTML, LaTeX) have a limited supported nesting depth.
+
+
+Explicit Markup
+---------------
+
+"Explicit markup" (:duref:`ref <explicit-markup-blocks>`) is used in reST for
+most constructs that need special handling, such as footnotes,
+specially-highlighted paragraphs, comments, and generic directives.
+
+An explicit markup block begins with a line starting with ``..`` followed by
+whitespace and is terminated by the next paragraph at the same level of
+indentation.  (There needs to be a blank line between explicit markup and normal
+paragraphs.  This may all sound a bit complicated, but it is intuitive enough
+when you write it.)
+
+
+.. _directives:
+
+Directives
+----------
+
+A directive (:duref:`ref <directives>`) is a generic block of explicit markup.
+Besides roles, it is one of the extension mechanisms of reST, and Sphinx makes
+heavy use of it.
+
+Docutils supports the following directives:
+
+* Admonitions: :dudir:`attention`, :dudir:`caution`, :dudir:`danger`,
+  :dudir:`error`, :dudir:`hint`, :dudir:`important`, :dudir:`note`,
+  :dudir:`tip`, :dudir:`warning` and the generic :dudir:`admonition`.
+  (Most themes style only "note" and "warning" specially.)
+
+* Images:
+
+  - :dudir:`image` (see also Images_ below)
+  - :dudir:`figure` (an image with caption and optional legend)
+
+* Additional body elements:
+
+  - :dudir:`contents` (a local, i.e. for the current file only, table of
+    contents)
+  - :dudir:`container` (a container with a custom class, useful to generate an
+    outer ``<div>`` in HTML)
+  - :dudir:`rubric` (a heading without relation to the document sectioning)
+  - :dudir:`topic`, :dudir:`sidebar` (special highlighted body elements)
+  - :dudir:`parsed-literal` (literal block that supports inline markup)
+  - :dudir:`epigraph` (a block quote with optional attribution line)
+  - :dudir:`highlights`, :dudir:`pull-quote` (block quotes with their own
+    class attribute)
+  - :dudir:`compound` (a compound paragraph)
+
+* Special tables:
+
+  - :dudir:`table` (a table with title)
+  - :dudir:`csv-table` (a table generated from comma-separated values)
+  - :dudir:`list-table` (a table generated from a list of lists)
+
+* Special directives:
+
+  - :dudir:`raw` (include raw target-format markup)
+  - :dudir:`include` (include reStructuredText from another file)
+    -- in Sphinx, when given an absolute include file path, this directive takes
+    it as relative to the source directory
+  - :dudir:`class` (assign a class attribute to the next element) [1]_
+
+* HTML specifics:
+
+  - :dudir:`meta` (generation of HTML ``<meta>`` tags)
+  - :dudir:`title` (override document title)
+
+* Influencing markup:
+
+  - :dudir:`default-role` (set a new default role)
+  - :dudir:`role` (create a new role)
+
+  Since these are only per-file, better use Sphinx' facilities for setting the
+  :confval:`default_role`.
+
+Do *not* use the directives :dudir:`sectnum`, :dudir:`header` and
+:dudir:`footer`.
+
+Directives added by Sphinx are described in :ref:`sphinxmarkup`.
+
+Basically, a directive consists of a name, arguments, options and content. (Keep
+this terminology in mind, it is used in the next chapter describing custom
+directives.)  Looking at this example, ::
+
+   .. function:: foo(x)
+                 foo(y, z)
+      :module: some.module.name
+
+      Return a line of text input from the user.
+
+``function`` is the directive name.  It is given two arguments here, the
+remainder of the first line and the second line, as well as one option
+``module`` (as you can see, options are given in the lines immediately following
+the arguments and indicated by the colons).  Options must be indented to the
+same level as the directive content.
+
+The directive content follows after a blank line and is indented relative to the
+directive start.
+
+
+Images
+------
+
+reST supports an image directive (:dudir:`ref <image>`), used like so::
+
+   .. image:: gnu.png
+      (options)
+
+When used within Sphinx, the file name given (here ``gnu.png``) must either be
+relative to the source file, or absolute which means that they are relative to
+the top source directory.  For example, the file ``sketch/spam.rst`` could refer
+to the image ``images/spam.png`` as ``../images/spam.png`` or
+``/images/spam.png``.
+
+Sphinx will automatically copy image files over to a subdirectory of the output
+directory on building (e.g. the ``_static`` directory for HTML output.)
+
+Interpretation of image size options (``width`` and ``height``) is as follows:
+if the size has no unit or the unit is pixels, the given size will only be
+respected for output channels that support pixels (i.e. not in LaTeX output).
+Other units (like ``pt`` for points) will be used for HTML and LaTeX output.
+
+Sphinx extends the standard docutils behavior by allowing an asterisk for the
+extension::
+
+   .. image:: gnu.*
+
+Sphinx then searches for all images matching the provided pattern and determines
+their type.  Each builder then chooses the best image out of these candidates.
+For instance, if the file name ``gnu.*`` was given and two files :file:`gnu.pdf`
+and :file:`gnu.png` existed in the source tree, the LaTeX builder would choose
+the former, while the HTML builder would prefer the latter.
+
+.. versionchanged:: 0.4
+   Added the support for file names ending in an asterisk.
+
+.. versionchanged:: 0.6
+   Image paths can now be absolute.
+
+
+Footnotes
+---------
+
+For footnotes (:duref:`ref <footnotes>`), use ``[#name]_`` to mark the footnote
+location, and add the footnote body at the bottom of the document after a
+"Footnotes" rubric heading, like so::
+
+   Lorem ipsum [#f1]_ dolor sit amet ... [#f2]_
+
+   .. rubric:: Footnotes
+
+   .. [#f1] Text of the first footnote.
+   .. [#f2] Text of the second footnote.
+
+You can also explicitly number the footnotes (``[1]_``) or use auto-numbered
+footnotes without names (``[#]_``).
+
+
+Citations
+---------
+
+Standard reST citations (:duref:`ref <citations>`) are supported, with the
+additional feature that they are "global", i.e. all citations can be referenced
+from all files.  Use them like so::
+
+   Lorem ipsum [Ref]_ dolor sit amet.
+
+   .. [Ref] Book or article reference, URL or whatever.
+
+Citation usage is similar to footnote usage, but with a label that is not
+numeric or begins with ``#``.
+
+
+Substitutions
+-------------
+
+reST supports "substitutions" (:duref:`ref <substitution-definitions>`), which
+are pieces of text and/or markup referred to in the text by ``|name|``.  They
+are defined like footnotes with explicit markup blocks, like this::
+
+   .. |name| replace:: replacement *text*
+
+or this::
+
+   .. |caution| image:: warning.png
+                :alt: Warning!
+
+See the :duref:`reST reference for substitutions <substitution-definitions>`
+for details.
+
+If you want to use some substitutions for all documents, put them into
+:confval:`rst_prolog` or put them into a separate file and include it into all
+documents you want to use them in, using the :rst:dir:`include` directive.  (Be
+sure to give the include file a file name extension differing from that of other
+source files, to avoid Sphinx finding it as a standalone document.)
+
+Sphinx defines some default substitutions, see :ref:`default-substitutions`.
+
+
+Comments
+--------
+
+Every explicit markup block which isn't a valid markup construct (like the
+footnotes above) is regarded as a comment (:duref:`ref <comments>`).  For
+example::
+
+   .. This is a comment.
+
+You can indent text after a comment start to form multiline comments::
+
+   ..
+      This whole indented block
+      is a comment.
+
+      Still in the comment.
+
+
+Source encoding
+---------------
+
+Since the easiest way to include special characters like em dashes or copyright
+signs in reST is to directly write them as Unicode characters, one has to
+specify an encoding.  Sphinx assumes source files to be encoded in UTF-8 by
+default; you can change this with the :confval:`source_encoding` config value.
+
+
+Gotchas
+-------
+
+There are some problems one commonly runs into while authoring reST documents:
+
+* **Separation of inline markup:** As said above, inline markup spans must be
+  separated from the surrounding text by non-word characters, you have to use a
+  backslash-escaped space to get around that.  See `the reference
+  <http://docutils.sf.net/docs/ref/rst/restructuredtext.html#inline-markup>`_
+  for the details.
+
+* **No nested inline markup:** Something like ``*see :func:`foo`*`` is not
+  possible.
+
+
+.. rubric:: Footnotes
+
+.. [1] When the default domain contains a :rst:dir:`class` directive, this directive
+       will be shadowed.  Therefore, Sphinx re-exports it as :rst:dir:`rst-class`.

+  How Properties of Mime Types are used by SQL Mode
+  =================================================
+
+  keywords:
+    A list of keywords you want to be highlighted.
+  functions:
+    A list of function names you want to be highlighted.
+  builtin:
+    A list of builtin types you want to be highlighted (if you want types to be of class "builtin" instead of "keyword").
+  operatorChars:
+    All characters that must be handled as operators.
+  client:
+    Commands parsed and executed by the client (not the server).
+  support:
+    A list of supported syntaxes which are not common, but are supported by more than 1 DBMS.
+    * ODBCdotTable: .tableName
+    * zerolessFloat: .1
+    * doubleQuote
+    * nCharCast: N'string'
+    * charsetCast: _utf8'string'
+    * commentHash: use # char for comments
+    * commentSlashSlash: use // for comments
+    * commentSpaceRequired: require a space after -- for comments
+  atoms:
+    Keywords that must be highlighted as atoms,. Some DBMS's support more atoms than others:
+    UNKNOWN, INFINITY, UNDERFLOW, NaN...
+  dateSQL:
+    Used for date/time SQL standard syntax, because not all DBMS's support same temporal types.

+      <dd>This switches the mode to parse HTML instead of XML. This

+      (such as <code>br</code>) do not require a closing tag.</dd>
+      <dt><code>alignCDATA (boolean)</code></dt>

+  // advancing the input stream and returning an AST node. Precedence
+  // of constructs (for example, the fact that `!x[1]` means `!(x[1])`
+  // instead of `(!x)[1]` is handled by the fact that the parser
+  // function that parses unary prefix operators is called first, and
+  // in turn calls the function that parses `[]` subscripts — that
+  // way, it'll receive the node for `x[1]` already parsed, and wraps
+  // *that* in the unary operator node.
+  //
+  // Acorn uses an [operator precedence parser][opp] to handle binary
+  // operator precedence, because it is much more compact than using
+  // the technique outlined above, which uses different, nesting
+  // functions to specify precedence, for all of the ten binary
+  // precedence levels that JavaScript defines.

+/**
+ * Helper to test CodeMirror highlighting modes. It pretty prints output of the
+ * highlighter and can check against expected styles.
+ *
+ * Mode tests are registered by calling test.mode(testName, mode,
+ * tokens), where mode is a mode object as returned by
+ * CodeMirror.getMode, and tokens is an array of lines that make up
+ * the test.
+ *
+ * These lines are strings, in which styled stretches of code are
+ * enclosed in brackets `[]`, and prefixed by their style. For
+ * example, `[keyword if]`. Brackets in the code itself must be
+ * duplicated to prevent them from being interpreted as token
+ * boundaries. For example `a[[i]]` for `a[i]`. If a token has
+ * multiple styles, the styles must be separated by ampersands, for
+ * example `[tag&error </hmtl>]`.
+ *
+ * See the test.js files in the css, markdown, gfm, and stex mode
+ * directories for examples.

+/**
+ * Summary of `ReactEventEmitter` event handling:
+ *
+ *  - Top-level delegation is used to trap native browser events. We normalize
+ *    and de-duplicate events to account for browser quirks.
+ *
+ *  - Forward these native events (with the associated top-level type used to
+ *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
+ *    to extract any synthetic events.
+ *
+ *  - The `EventPluginHub` will then process each event by annotating them with
+ *    "dispatches", a sequence of listeners and IDs that care about that event.
+ *
+ *  - The `EventPluginHub` then dispatches the events.

+ * Collection of methods that allow declaration and validation of props that are
+ * supplied to React components. Example usage:
+ *
+ *   var Props = require('ReactPropTypes');
+ *   var MyArticle = React.createClass({
+ *     propTypes: {
+ *       // An optional string prop named "description".
+ *       description: Props.string,
+ *
+ *       // A required enum prop named "category".
+ *       category: Props.oneOf(['News','Photos']).isRequired,
+ *
+ *       // A prop named "dialog" that requires an instance of Dialog.
+ *       dialog: Props.instanceOf(Dialog).isRequired
+ *     },
+ *     render: function() { ... }
+ *   });
+ *
+ * A more formal specification of how these methods are used:
+ *
+ *   type := array|bool|func|object|number|string|oneOf([...])|instanceOf(...)
+ *   decl := ReactPropTypes.{type}(.isRequired)?
+ *
+ * Each and every declaration produces a function with the same signature. This
+ * allows the creation of custom validation functions. For example:
+ *
+ *   var Props = require('ReactPropTypes');
+ *   var MyLink = React.createClass({
+ *     propTypes: {
+ *       // An optional string or URI prop named "href".

+See `use_cent_tuning` for setting the cent tuning value locally for a specific thread or `live_loop`. This is a global value and will shift the tuning for *all* notes. It will also persist for the entire session.
 
+Important note: the cent tuning set by `set_cent_tuning!` is independent of any thread-local cent tuning values set by `use_cent_tuning` or `with_cent_tuning`. ",

 If note: opt is `nil`, `:r` or `:rest`, play is ignored and treated as a rest. Also, if the `on:` opt is specified and returns `false`, or `nil` then play is similarly ignored and treated as a rest.
 
+If the synth name is `nil` behaviour is identical to that of `play` in that the `current_synth` will determine the actual synth triggered.

 Note that the default opts listed are only a guide to the most common opts across all the synths. Not all synths support all the default opts and each synth typically supports many more opts specific to that synth. For example, the `:tb303` synth supports 45 unique opts.

Sonic Pi comes with lots of great samples included (see the section under help) but you can also load and play `.wav`, `.wave`, `.aif`, `.aiff` or `.flac` files from anywhere on your computer too.

-The sampler synth has two separate envelopes - one for amplitude and one for the cutoff value for a resonant low pass filter. These work very similar to the standard synth envelopes except for two major differences. Firstly, the envelope times do not stretch or shrink to match the BPM. Secondly, the sustain time by default stretches to make the envelope fit the length of the sample. This is explained in detail in the tutorial.
+There are many opts for manipulating the playback. For example, the `rate:` opt affects both the speed and the pitch of the playback. To control the rate of the sample in a pitch-meaningful way take a look at the `rpitch:` opt.
+
+The sampler synth has three separate envelopes - one for amplitude, one for a low pass filter and another for a high pass filter. These work very similar to the standard synth envelopes except for two major differences. Firstly, the envelope times do not stretch or shrink to match the BPM. Secondly, the sustain time by default stretches to make the envelope fit the length of the sample. This is explained in detail in the tutorial.
+
+Samples are loaded on-the-fly when first requested (and subsequently remembered). If the sample loading process takes longer than the schedule ahead time, the sample trigger will be skipped rather than be played late and out of time. To avoid this you may preload any samples you wish to work with using `load_sample` or `load_samples`.
+
+Finally, the sampler supports a powerful filtering system to make it easier to work with large folders of samples. The filter commands must be used before the first standard opt. There are six kinds of filter parameters you may use:
+
+1. Folder strings - `\"/foo/bar\"` - which will add all samples within the folder to the set of candidates.
+2. Sample strings - `\"/path/to/sample.wav\"` - which will add the specific sample to the set of candidates.
+3. Other strings - `\"foobar\"` - which will filter the candidates based on whether the filename contains the string.
+4. Regular expressions - `/b[aA]z.*/` - which will filter the candidates based on whether the regular expression matches the filename.
+5. Keywords - `:quux` - will filter the candidates based on whether the keyword is a direct match of the filename (without extension).
+7. Numbers - `0` - will select the candidate with that index (wrapping round like a ring if necessary).
+8. Lists of the above - `[\"/foo/bar\", \"baz\", /0-9.*/]` - will recurse down and work through the internal filter parameters as if they were in the top level.
+
+By combining commands which add to the candidates and then filtering those candidates it is possible to work with folders full of samples in very powerful ways. Note that the specific ordering of filter parameters is irrelevant with the exception of the numbers - in which case the last number is the index. All the candidates will be gathered first before the filters are applied.

The stereo input is expected to be on consecutive sound card channels.
+
+As with all Sonic Pi synths, there is a default envelope which determines the duration of the lifetime of the synth. Therefore, to get a continuous stream of audio, you need to place consecutive calls to this synth in iteration or a `live_loop`. For example:
+
+```
+live_loop :playback do
+```
+
+```
+   synth :sound_in_stereo, sustain: 8
+```
+
+```
+   sleep 8
+```
+
+```
+end
+```
+
+Note that if the microphone and speaker are close together (on a laptop or in a small room) you will potentially get a harsh feedback sound."

+= Active Support -- Utility classes and Ruby extensions from Rails
+
+Active Support is a collection of utility classes and standard library
+extensions that were found useful for the Rails framework. These additions
+reside in this package so they can be loaded as needed in Ruby projects
+outside of Rails.
+
+
+== Download and installation
+
+The latest version of Active Support can be installed with RubyGems:
+
+  % [sudo] gem install activesupport
+
+Source code can be downloaded as part of the Rails project on GitHub:
+
+* https://github.com/rails/rails/tree/master/activesupport
+
+
+== License
+
+Active Support is released under the MIT license:
+
+* http://www.opensource.org/licenses/MIT
+
+
+== Support
+
+API documentation is at:

+module ActiveSupport
+  # Callbacks are code hooks that are run at key points in an object's life cycle.
+  # The typical use case is to have a base class define a set of callbacks
+  # relevant to the other functionality it supplies, so that subclasses can
+  # install callbacks that enhance or modify the base functionality without
+  # needing to override or redefine methods of the base class.
+  #
+  # Mixing in this module allows you to define the events in the object's
+  # life cycle that will support callbacks (via +ClassMethods.define_callbacks+),
+  # set the instance methods, procs, or callback objects to be called (via
+  # +ClassMethods.set_callback+), and run the installed callbacks at the
+  # appropriate times (via +run_callbacks+).
+  #
+  # Three kinds of callbacks are supported: before callbacks, run before a
+  # certain event; after callbacks, run after the event; and around callbacks,
+  # blocks that surround the event, triggering it when they yield. Callback code
+  # can be contained in instance methods, procs or lambdas, or callback objects
+  # that respond to certain predetermined methods. See +ClassMethods.set_callback+

+  #     include Bar # Bar is the module that Host really needs
+  #   end
+  #
+  # But why should +Host+ care about +Bar+'s dependencies, namely +Foo+? We
+  # could try to hide these from +Host+ directly including +Foo+ in +Bar+:
+  #
+  #   module Bar
+  #     include Foo

+  #   end
+  #
+  # Unfortunately this won't work, since when +Foo+ is included, its <tt>base</tt>
+  # is the +Bar+ module, not the +Host+ class. With <tt>ActiveSupport::Concern</tt>,

+  # no additional state to encapsulate or we're making DSL-style declarations
+  # about the parent class, introducing new collaborators can obfuscate rather
+  # than simplify.
+  #
+  # The typical route is to just dump everything in a monolithic class, perhaps
+  # with a comment, as a least-bad alternative. Using modules in separate files
+  # means tedious sifting to get a big-picture view.

+    # These sequences have identical meaning as the original characters inside the

+    #

+    #
+    #   <script>
+    #     var currentUser = <%= raw json_escape(current_user.to_json) %>;
+    #   </script>
+    #
+    # It is necessary to +raw+ the result of +json_escape+, so that quotation marks
+    # don't get converted to <tt>"</tt> entities. +json_escape+ doesn't
+    # automatically flag the result as HTML safe, since the raw value is unsafe to
+    # use inside HTML attributes.
+    #
+    # If you need to output JSON elsewhere in your HTML, you can just do something
+    # like this, as any unsafe characters (including quotation marks) will be
+    # automatically escaped for you:
+    #
+    #   <div data-user-info="<%= current_user.to_json %>">...</div>
+    #
+    # WARNING: this helper only works with valid JSON. Using this on non-JSON values
+    # will open up serious XSS vulnerabilities. For example, if you replace the
+    # +current_user.to_json+ in the example above with user input instead, the browser
+    # will happily eval() that string as JavaScript.
+    #
+    # The escaping performed in this method is identical to those performed in the
+    # Active Support JSON encoder when +ActiveSupport.escape_html_entities_in_json+ is
+    # set to true. Because this transformation is idempotent, this helper can be
+    # applied even if +ActiveSupport.escape_html_entities_in_json+ is already true.
+    #
+    # Therefore, when you are unsure if +ActiveSupport.escape_html_entities_in_json+
+    # is enabled, or if you are unsure where your JSON string originated from, it
+    # is recommended that you always apply this helper (other libraries, such as the

+module ActiveSupport
+  # = Notifications
+  #
+  # <tt>ActiveSupport::Notifications</tt> provides an instrumentation API for
+  # Ruby.
+  #
+  # == Instrumenters
+  #
+  # To instrument an event you just need to do:
+  #
+  #   ActiveSupport::Notifications.instrument('render', extra: :information) do
+  #     render text: 'Foo'
+  #   end
+  #
+  # That executes the block first and notifies all subscribers once done.
+  #
+  # In the example above +render+ is the name of the event, and the rest is called
+  # the _payload_. The payload is a mechanism that allows instrumenters to pass
+  # extra information to subscribers. Payloads consist of a hash whose contents
+  # are arbitrary and generally depend on the event.
+  #
+  # == Subscribers
+  #
+  # You can consume those events and the information they provide by registering
+  # a subscriber.
+  #
+  #   ActiveSupport::Notifications.subscribe('render') do |name, start, finish, id, payload|
+  #     name    # => String, name of the event (such as 'render' from above)
+  #     start   # => Time, when the instrumented block started execution
+  #     finish  # => Time, when the instrumented block ended execution
+  #     id      # => String, unique ID for this notification
+  #     payload # => Hash, the payload
+  #   end
+  #
+  # For instance, let's store all "render" events in an array:
+  #
+  #   events = []
+  #
+  #   ActiveSupport::Notifications.subscribe('render') do |*args|
+  #     events << ActiveSupport::Notifications::Event.new(*args)
+  #   end
+  #
+  # That code returns right away, you are just subscribing to "render" events.
+  # The block is saved and will be called whenever someone instruments "render":
+  #
+  #   ActiveSupport::Notifications.instrument('render', extra: :information) do
+  #     render text: 'Foo'
+  #   end
+  #
+  #   event = events.first
+  #   event.name      # => "render"
+  #   event.duration  # => 10 (in milliseconds)
+  #   event.payload   # => { extra: :information }
+  #
+  # The block in the <tt>subscribe</tt> call gets the name of the event, start
+  # timestamp, end timestamp, a string with a unique identifier for that event
+  # (something like "535801666f04d0298cd6"), and a hash with the payload, in
+  # that order.
+  #
+  # If an exception happens during that particular instrumentation the payload will
+  # have a key <tt>:exception</tt> with an array of two elements as value: a string with
+  # the name of the exception class, and the exception message.
+  #
+  # As the previous example depicts, the class <tt>ActiveSupport::Notifications::Event</tt>
+  # is able to take the arguments as they come and provide an object-oriented
+  # interface to that data.
+  #
+  # It is also possible to pass an object as the second parameter passed to the
+  # <tt>subscribe</tt> method instead of a block:
+  #
+  #   module ActionController
+  #     class PageRequest
+  #       def call(name, started, finished, unique_id, payload)
+  #         Rails.logger.debug ['notification:', name, started, finished, unique_id, payload].join(' ')
+  #       end
+  #     end
+  #   end
+  #
+  #   ActiveSupport::Notifications.subscribe('process_action.action_controller', ActionController::PageRequest.new)
+  #
+  # resulting in the following output within the logs including a hash with the payload:
+  #
+  #   notification: process_action.action_controller 2012-04-13 01:08:35 +0300 2012-04-13 01:08:35 +0300 af358ed7fab884532ec7 {
+  #      controller: "Devise::SessionsController",
+  #      action: "new",
+  #      params: {"action"=>"new", "controller"=>"devise/sessions"},
+  #      format: :html,
+  #      method: "GET",
+  #      path: "/login/sign_in",
+  #      status: 200,
+  #      view_runtime: 279.3080806732178,
+  #      db_runtime: 40.053
+  #    }
+  #
+  # You can also subscribe to all events whose name matches a certain regexp:
+  #
+  #   ActiveSupport::Notifications.subscribe(/render/) do |*args|
+  #     ...
+  #   end
+  #
+  # and even pass no argument to <tt>subscribe</tt>, in which case you are subscribing
+  # to all events.
+  #
+  # == Temporary Subscriptions
+  #
+  # Sometimes you do not want to subscribe to an event for the entire life of
+  # the application. There are two ways to unsubscribe.
+  #
+  # WARNING: The instrumentation framework is designed for long-running subscribers,
+  # use this feature sparingly because it wipes some internal caches and that has
+  # a negative impact on performance.
+  #
+  # === Subscribe While a Block Runs
+  #
+  # You can subscribe to some event temporarily while some block runs. For
+  # example, in
+  #
+  #   callback = lambda {|*args| ... }
+  #   ActiveSupport::Notifications.subscribed(callback, "sql.active_record") do
+  #     ...
+  #   end
+  #
+  # the callback will be called for all "sql.active_record" events instrumented
+  # during the execution of the block. The callback is unsubscribed automatically
+  # after that.
+  #
+  # === Manual Unsubscription
+  #
+  # The +subscribe+ method returns a subscriber object:
+  #
+  #   subscriber = ActiveSupport::Notifications.subscribe("render") do |*args|
+  #     ...
+  #   end
+  #
+  # To prevent that block from being called anymore, just unsubscribe passing
+  # that reference:
+  #
+  #   ActiveSupport::Notifications.unsubscribe(subscriber)
+  #
+  # == Default Queue
+  #
+  # Notifications ships with a queue implementation that consumes and publishes events
+  # to all log subscribers. You can use any queue implementation you want.
+  #
+  module Notifications
+    class << self
+      attr_accessor :notifier

+  # The TimeZone class serves as a wrapper around TZInfo::Timezone instances.
+  # It allows us to do the following:
+  #
+  # * Limit the set of zones provided by TZInfo to a meaningful subset of 146
+  #   zones.
+  # * Retrieve and display zones with a friendlier name
+  #   (e.g., "Eastern Time (US & Canada)" instead of "America/New_York").
+  # * Lazily load TZInfo::Timezone instances only when they're needed.
+  # * Create ActiveSupport::TimeWithZone instances via TimeZone's +local+,
+  #   +parse+, +at+ and +now+ methods.
+  #
+  # If you set <tt>config.time_zone</tt> in the Rails Application, you can
+  # access this TimeZone object via <tt>Time.zone</tt>:
+  #
+  #   # application.rb:

+module AST
+  # Node is an immutable class, instances of which represent abstract
+  # syntax tree nodes. It combines semantic information (i.e. anything
+  # that affects the algorithmic properties of a program) with
+  # meta-information (line numbers or compiler intermediates).
+  #
+  # Notes on inheritance
+  # ====================
+  #
+  # The distinction between semantics and metadata is important. Complete
+  # semantic information should be contained within just the {#type} and
+  # {#children} of a Node instance; in other words, if an AST was to be
+  # stripped of all meta-information, it should remain a valid AST which
+  # could be successfully processed to yield a result with the same
+  # algorithmic properties.
+  #
+  # Thus, Node should never be inherited in order to define methods which
+  # affect or return semantic information, such as getters for `class_name`,
+  # `superclass` and `body` in the case of a hypothetical `ClassNode`. The
+  # correct solution is to use a generic Node with a {#type} of `:class`
+  # and three children. See also {Processor} for tips on working with such
+  # ASTs.
+  #
+  # On the other hand, Node can and should be inherited to define
+  # application-specific metadata (see also {#initialize}) or customize the
+  # printing format. It is expected that an application would have one or two
+  # such classes and use them across the entire codebase.
+  #
+  # The rationale for this pattern is extensibility and maintainability.
+  # Unlike static ones, dynamic languages do not require the presence of a
+  # predefined, rigid structure, nor does it improve dispatch efficiency,
+  # and while such a structure can certainly be defined, it does not add
+  # any value but incurs a maintaining cost.
+  # For example, extending the AST even with a transformation-local
+  # temporary node type requires making globally visible changes to
+  # the codebase.
+  #
+  class Node
+    # Returns the type of this node.
+    # @return [Symbol]

+    # The arguments `type` and `children` are converted with `to_sym` and
+    # `to_a` respectively. Additionally, the result of converting `children`
+    # is frozen. While mutating the arguments is generally considered harmful,
+    # the most common case is to pass an array literal to the constructor. If

+  # Processor is a class which helps transforming one AST into another.
+  # In a nutshell, the {#process} method accepts a {Node} and dispatches
+  # it to a handler corresponding to its type, and returns a (possibly)
+  # updated variant of the node.
+  #
+  # Processor has a set of associated design patterns. They are best
+  # explained with a concrete example. Let's define a simple arithmetic
+  # language and an AST format for it:
+  #
+  # Terminals (AST nodes which do not have other AST nodes inside):
+  #
+  #   * `(integer <int-literal>)`,
+  #
+  # Nonterminals (AST nodes with other nodes as children):
+  #
+  #   * `(add <node> <node>)`,
+  #   * `(multiply <node> <node>)`,
+  #   * `(divide <node> <node>)`,
+  #   * `(negate <node>)`,
+  #   * `(store <node> <string-literal>)`: stores value of `<node>` into a variable named `<string-literal>`,
+  #   * `(load <string-literal>)`: loads value of a variable named `<string-literal>`,
+  #   * `(each <node> ...): computes each of the `<node>`s and prints the result.
+  #
+  # All AST nodes have the same Ruby class, and therefore they don't
+  # know how to traverse themselves. (A solution which dynamically checks the
+  # type of children is possible, but is slow and error-prone.) So, a subclass
+  # of Processor which knows how to traverse the entire tree should be defined.
+  # Such subclass has a handler for each nonterminal node which recursively
+  # processes children nodes:
+  #
+  #     require 'ast'
+  #
+  #     class ArithmeticsProcessor < AST::Processor
+  #       # This method traverses any binary operators such as (add) or (multiply).
+  #       def process_binary_op(node)
+  #         # Children aren't decomposed automatically; it is suggested to use Ruby
+  #         # multiple assignment expansion, as it is very convenient here.
+  #         left_expr, right_expr = *node
+  #
+  #         # AST::Node#updated won't change node type if nil is passed as a first
+  #         # argument, which allows to reuse the same handler for multiple node types
+  #         # using `alias' (below).
+  #         node.updated(nil, [
+  #           process(left_expr),
+  #           process(right_expr)
+  #         ])
+  #       end
+  #       alias on_add      process_binary_op
+  #       alias on_multiply process_binary_op
+  #       alias on_divide   process_binary_op
+  #
+  #       def on_negate(node)
+  #         # It is also possible to use #process_all for more compact code
+  #         # if every child is a Node.
+  #         node.updated(nil, process_all(node))
+  #       end
+  #
+  #       def on_store(node)
+  #         expr, variable_name = *node
+  #
+  #         # Note that variable_name is not a Node and thus isn't passed to #process.
+  #         node.updated(nil, [
+  #           process(expr),
+  #           variable_name
+  #         ])
+  #       end
+  #
+  #       # (load) is effectively a terminal node, and so it does not need

+  #         node.updated(nil, process_all(node))

+  #
+  # Let's test our ArithmeticsProcessor:
+  #
+  #     include AST::Sexp
+  #     expr = s(:add, s(:integer, 2), s(:integer, 2))
+  #
+  #     p ArithmeticsProcessor.new.process(expr) == expr # => true
+  #
+  # As expected, it does not change anything at all. This isn't actually
+  # very useful, so let's now define a Calculator, which will compute the
+  # expression values:
+  #
+  #     # This Processor folds nonterminal nodes and returns an (integer)
+  #     # terminal node.
+  #     class ArithmeticsCalculator < ArithmeticsProcessor
+  #       def compute_op(node)
+  #         # First, node children are processed and then unpacked to local

+  #           ])

+  #
+  # Let's check:
+  #
+  #     p ArithmeticsCalculator.new.process(expr) # => (integer 4)
+  #
+  # Excellent, the calculator works! Now, a careful reader could notice that
+  # the ArithmeticsCalculator does not know how to divide numbers. What if we

+atomic: An atomic reference implementation for JRuby, Rubinius, and MRI.
+========================================================================
+
+[![Build Status](https://travis-ci.org/headius/ruby-atomic.png?branch=master)](https://travis-ci.org/headius/ruby-atomic)
+
+Summary
+=======
+
+This library provides:
+
+* an Atomic class that guarantees atomic updates to its contained value
+
+The Atomic class provides accessors for the contained "value" plus two update methods:
+
+* update will run the provided block, passing the current value and replacing it with the block result if the value has not been changed in the meantime. It may run the block repeatedly if there are other concurrent updates in progress.
+* try_update will run the provided block, passing the current value and replacing it with the block result. If the value changes before the update can happen, it will throw an Atomic::ConcurrentUpdateError.
+
+The atomic repository is at http://github.com/headius/ruby-atomic.
+
+Usage
+=====
+
+The simplest way to use "atomic" is to call the "update" or "try_update" methods.
+
+"try_update" and "update" both call the given block, passing the current value and using the block's result as the new value. If the value is updated by another thread before the block completes, "try update" raises a ConcurrentUpdateError and "update" retries the block. Because "update" may call the block several times when multiple threads are all updating the same value, the block's logic should be kept as simple as possible.
+
+```ruby
+require 'atomic'
+
+my_atomic = Atomic.new(0)
+my_atomic.update {|v| v + 1}
+begin
+  my_atomic.try_update {|v| v + 1}
+rescue Atomic::ConcurrentUpdateError => cue
+  # deal with it (retry, propagate, etc)
+end
+```
+
+It's also possible to use the regular get/set operations on the Atomic, if you want to avoid the exception and respond to contended changes in some other way.
+
+```ruby
+my_atomic = Atomic.new(0)
+my_atomic.value # => 0
+my_atomic.value = 1
+my_atomic.swap(2) # => 1
+my_atomic.compare_and_swap(2, 3) # => true, updated to 3
+my_atomic.compare_and_swap(2, 3) # => false, current is not 2
+```
+
+Building
+========
+
+As of 1.1.0, JDK8 is required to build the atomic gem, since it attempts to use the new atomic Unsafe.getAndSetObject method only in JDK8. The resulting code should still work fine as far back as Java 5.

+## DESCRIPTION:
+
+A iterations per second enhancement to Benchmark.
+
+## FEATURES/PROBLEMS:
+
+ * benchmark/ips - benchmarks a blocks iterations/second. For short snippits
+   of code, ips automatically figures out how many times to run the code
+   to get interesting data. No more guessing at random iteration counts!
+
+## SYNOPSIS:
+
+```ruby
+require 'benchmark/ips'
+
+Benchmark.ips do |x|
+  # Configure the number of seconds used during
+  # the warmup phase (default 2) and calculation phase (default 5)
+  x.config(:time => 5, :warmup => 2)
+
+  # These parameters can also be configured this way
+  x.time = 5
+  x.warmup = 2
+
+  # Typical mode, runs the block as many times as it can
+  x.report("addition") { 1 + 2 }
+
+  # To reduce overhead, the number of iterations is passed in
+  # and the block must run the code the specific number of times.
+  # Used for when the workload is very small and any overhead
+  # introduces incorrectable errors.
+  x.report("addition2") do |times|
+    i = 0
+    while i < times
+      1 + 2
+      i += 1
+    end
+  end
+
+  # To reduce overhead even more, grafts the code given into
+  # the loop that performs the iterations internally to reduce
+  # overhead. Typically not needed, use the |times| form instead.
+  x.report("addition3", "1 + 2")
+
+  # Really long labels should be formatted correctly
+  x.report("addition-test-long-label") { 1 + 2 }
+
+  # Compare the iterations per second of the various reports!
+  x.compare!
+end
+```
+
+This will generate the following report:
+
+```

+            addition    71.254k i/100ms
+           addition2    68.658k i/100ms
+           addition3    83.079k i/100ms
+addition-test-long-label
+                        70.129k i/100ms

+           addition3    23.958M (±10.1%) i/s -    115.064M
+addition-test-long-label
+                         5.014M (± 9.1%) i/s -     24.545M
+
+Comparison:
+           addition2: 24011974.8 i/s
+           addition3: 23958619.8 i/s - 1.00x slower
+addition-test-long-label:  5014756.0 i/s - 4.79x slower
+            addition:  4955278.9 i/s - 4.85x slower
+```
+
+Benchmark/ips will report the number of iterations per second for a given block
+of code. When analyzing the results, notice the percent of [standard
+deviation](http://en.wikipedia.org/wiki/Standard\_deviation) which tells us how
+spread out our measurements are from the average. A high standard deviation
+could indicate the results having too much variability.
+
+One benefit to using this method is benchmark-ips automatically determines the
+data points for testing our code, so we can focus on the results instead of
+guessing iteration counts as we do with the traditional Benchmark library.
+
+### Custom Suite
+
+Pass a custom suite to disable garbage collection during benchmark:
+
+```ruby
+require 'benchmark/ips'
+
+# Enable and start GC before each job run. Disable GC afterwards.
+#
+# Inspired by https://www.omniref.com/ruby/2.2.1/symbols/Benchmark/bm?#annotation=4095926&line=182
+class GCSuite
+  def warming(*)
+    run_gc
+  end
+
+  def running(*)
+    run_gc
+  end
+
+  def warmup_stats(*)
+  end
+
+  def add_report(*)
+  end
+
+  private
+
+  def run_gc
+    GC.enable
+    GC.start
+    GC.disable
+  end
+end
+
+suite = GCSuite.new
+
+Benchmark.ips do |x|
+  x.config(:suite => suite)
+  x.report("job1") { ... }
+  x.report("job2") { ... }
+end
+```

+BlankSlate
+===
+
+BlankSlate provides an abstract base class with no predefined
+methods (except for <tt>\_\_send__</tt> and <tt>\_\_id__</tt>).
+BlankSlate is useful as a base class when writing classes that
+depend upon <tt>method_missing</tt> (e.g. dynamic proxies).
+
+Copyright 2004, 2006 by Jim Weirich (jim at weirichhouse.org).
+All rights reserved.
+
+
+Extracted from Builder because, for no conceivable reason,
+blankslate isn't in its own gem. Gemified by David Masover,
+moved to gemcutter by Jack Danger Canty (gemcutter at 6brand.com
+if you'd like to own this gem).
+
+Explanation on extraction from David Masover:
+
+So, Builder seems to have the most complete implementation of
+BlankSlate, short of Ruby 1.9's BasicObject. The problem is,
+this is part of Builder, and still inside the Builder gem.
+
+It's especially frustrating, because the Builder source
+(lib/builder/blankslate.rb) seems to acknowledge that there
+should be a separate gem. But the only reference I can find
+refers to onestepback.org's gem repository, which isn't working.

+# => NameError: undefined local variable or method `full_name' for main:Object
+#
+#     Did you mean? @full_name
+#
+```
+
+### NoMethodError
+
+```ruby
+# In a Rails controller:
+params.with_inddiferent_access
+# => NoMethodError: undefined method `with_inddiferent_access' for {}:Hash
+#
+#     Did you mean? #with_indifferent_access

+# ruby-ffi https://wiki.github.com/ffi/ffi [![Build Status](https://travis-ci.org/ffi/ffi.png?branch=master)](https://travis-ci.org/ffi/ffi)
+
+## Description
+
+Ruby-FFI is a ruby extension for programmatically loading dynamic
+libraries, binding functions within them, and calling those functions
+from Ruby code. Moreover, a Ruby-FFI extension works without changes
+on Ruby and JRuby. [Discover why you should write your next extension
+using Ruby-FFI](https://wiki.github.com/ffi/ffi/why-use-ffi).
+
+## Features/problems
+
+* Intuitive DSL
+* Supports all C native types
+* C structs (also nested), enums and global variables
+* Callbacks from C to ruby
+* Automatic garbage collection of native memory
+
+## Synopsis
+
+```ruby
+require 'ffi'
+
+module MyLib
+  extend FFI::Library
+  ffi_lib 'c'
+  attach_function :puts, [ :string ], :int
+end
+
+MyLib.puts 'Hello, World using libc!'
+```
+
+For less minimalistic and more sane examples you may look at:
+
+* the samples/ folder
+* the examples on the [wiki](https://wiki.github.com/ffi/ffi)
+* the projects using FFI listed on this page (https://wiki.github.com/ffi/ffi/projects-using-ffi)
+
+## Requirements
+
+You need a sane building environment in order to compile the extension.
+At a minimum, you will need:
+* A C compiler (e.g. Xcode on OSX, gcc on everything else)
+* libffi development library - this is commonly in the libffi-dev or libffi-devel
+
+## Installation
+
+From rubygems:
+
+    [sudo] gem install ffi
+
+or from the git repository on github:
+
+    git clone git://github.com/ffi/ffi.git
+    cd ffi
+    rake gem:install
+
+## License
+
+The ffi library is covered by the BSD license, also see the LICENSE file.
+The specs are shared with Rubyspec and are licensed by the same license
+as Rubyspec, see the LICENSE.SPECS file.

+Status
+======
+
+libffi-3.0.10 was released on August 23, 2011. Check the libffi web
+page for updates: <URL:http://sourceware.org/libffi/>.
+
+
+What is libffi?
+===============
+
+Compilers for high level languages generate code that follow certain
+conventions. These conventions are necessary, in part, for separate
+compilation to work. One such convention is the "calling
+convention". The "calling convention" is essentially a set of
+assumptions made by the compiler about where function arguments will
+be found on entry to a function. A "calling convention" also specifies
+where the return value for a function is found.
+
+Some programs may not know at the time of compilation what arguments
+are to be passed to a function. For instance, an interpreter may be
+told at run-time about the number and types of arguments used to call
+a given function. Libffi can be used in such programs to provide a
+bridge from the interpreter program to compiled code.
+
+The libffi library provides a portable, high level programming
+interface to various calling conventions. This allows a programmer to
+call any function specified by a call interface description at run
+time.  
+
+FFI stands for Foreign Function Interface.  A foreign function
+interface is the popular name for the interface that allows code
+written in one language to call code written in another language. The
+libffi library really only provides the lowest, machine dependent
+layer of a fully featured foreign function interface. A layer must
+exist above libffi that handles type conversions for values passed
+between the two languages.
+
+
+Supported Platforms
+===================
+
+Libffi has been ported to many different platforms.
+For specific configuration details and testing status, please

+
+Installing libffi
+=================
+
+First you must configure the distribution for your particular
+system. Go to the directory you wish to build libffi in and run the
+"configure" program found in the root directory of the libffi source
+distribution.
+
+You may want to tell configure where to install the libffi library and
+header files. To do that, use the --prefix configure switch.  Libffi
+will install under /usr/local by default. 
+
+If you want to enable extra run-time debugging checks use the the
+--enable-debug configure switch. This is useful when your program dies
+mysteriously while using libffi. 
+
+Another useful configure switch is --enable-purify-safety. Using this
+will add some extra code which will suppress certain warnings when you
+are using Purify with libffi. Only use this switch when using 
+Purify, as it will slow down the library.
+
+It's also possible to build libffi on Windows platforms with
+Microsoft's Visual C++ compiler.  In this case, use the msvcc.sh
+wrapper script during configuration like so:
+
+path/to/configure CC=path/to/msvcc.sh LD=link CPP=\"cl -nologo -EP\"
+
+For 64-bit Windows builds, use CC="path/to/msvcc.sh -m64".
+You may also need to specify --build appropriately. When building with MSVC
+under a MingW environment, you may need to remove the line in configure
+that sets 'fix_srcfile_path' to a 'cygpath' command. ('cygpath' is not
+present in MingW, and is not required when using MingW-style paths.)
+
+For iOS builds, refer to the build-ios.sh script for guidance.
+
+Configure has many other options. Use "configure --help" to see them all.
+
+Once configure has finished, type "make". Note that you must be using
+GNU make.  You can ftp GNU make from prep.ai.mit.edu:/pub/gnu.
+
+To ensure that libffi is working as advertised, type "make check".
+This will require that you have DejaGNU installed.
+
+To install the library and header files, type "make install".

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+# One issue with vendor `install' (even GNU) is that you can't

+# is unlikely to handle the host's binaries.
+# Fortunately install-sh will honor a STRIPPROG variable, so we
+# always use install-sh in `make install-strip', and initialize
+# STRIPPROG with the value of the STRIP variable (set by the user).

+\`configure' configures libffi 3.0.10 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
+  --with-pic              try to use only PIC/non-PIC objects [default=use
+                          both]
+  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
+  --with-sysroot=DIR Search for dependent libraries within DIR
+                        (or the compiler's sysroot if not specified).
+  --with-gcc-arch=<arch>  use architecture <arch> for gcc -march/-mtune,
+                          instead of guessing
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CCAS        assembler compiler command (defaults to CC)
+  CCASFLAGS   assembler compiler flags (defaults to CFLAGS)
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+Run PROGRAMS ARGS to compile a file, generating dependencies
+as side-effects.
+
+Environment variables:
+  depmode     Dependency tracking mode.
+  source      Source file read by `PROGRAMS ARGS'.
+  object      Object file output by `PROGRAMS ARGS'.
+  DEPDIR      directory where to store dependencies.
+  depfile     Dependency file to output.
+  tmpdepfile  Temporary file to use when outputing dependencies.
+  libtool     Whether libtool is used (yes/no).

+   The basic API is described in the README file.
+
+   The raw API is designed to bypass some of the argument packing
+   and unpacking on architectures for which it can be avoided.
+
+   The closure API allows interpreted functions to be packaged up
+   inside a C function pointer, so that they can be called as C functions,
+   with no understanding on the client side that they are interpreted.
+   It can also be used in other cases in which it is necessary to package
+   up a user specified parameter and a function pointer as a single
+   function pointer.
+
+   The closure API must be implemented in order to get its functionality,
+   e.g. for use by gij.  Routines are provided to emulate the raw API
+   if the underlying platform doesn't allow faster implementation.
+
+   More details on the raw and cloure API can be found in:
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00138.html
+
+   and
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00174.html

+   The basic API is described in the README file.
+
+   The raw API is designed to bypass some of the argument packing
+   and unpacking on architectures for which it can be avoided.
+
+   The closure API allows interpreted functions to be packaged up
+   inside a C function pointer, so that they can be called as C functions,
+   with no understanding on the client side that they are interpreted.
+   It can also be used in other cases in which it is necessary to package
+   up a user specified parameter and a function pointer as a single
+   function pointer.
+
+   The closure API must be implemented in order to get its functionality,
+   e.g. for use by gij.  Routines are provided to emulate the raw API
+   if the underlying platform doesn't allow faster implementation.
+
+   More details on the raw and cloure API can be found in:
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00138.html

+# Here are a set of rules to help you update your library version

+# 
+# 1. Start with version information of `0:0:0' for each libtool library.

+# 2. Update the version information only immediately before a public
+#    release of your software. More frequent updates are unnecessary,
+#    and only guarantee that the current interface number gets larger
+#    faster.
+#
+# 3. If the library source code has changed at all since the last
+#    update, then increment revision (`c:r:a' becomes `c:r+1:a').
+#
+# 4. If any interfaces have been added, removed, or changed since the
+#    last update, increment current, and set revision to 0.
+#
+# 5. If any interfaces have been added since the last public release,

+#
+# SYNOPSIS
+#
+#   AX_CC_MAXOPT
+#
+# DESCRIPTION
+#
+#   Try to turn on "good" C optimization flags for various compilers and
+#   architectures, for some definition of "good". (In our case, good for
+#   FFTW and hopefully for other scientific codes. Modify as needed.)
+#
+#   The user can override the flags by setting the CFLAGS environment
+#   variable. The user can also specify --enable-portable-binary in order to
+#   disable any optimization flags that might result in a binary that only
+#   runs on the host architecture.
+#
+#   Note also that the flags assume that ANSI C aliasing rules are followed
+#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
+#   computations can be re-ordered as needed.
+#
+#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_COMPILER_VENDOR,
+#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

+#
+# DESCRIPTION
+#
+#   Try to find a compiler option that enables most reasonable warnings.
+#
+#   For the GNU compiler it will be -Wall (and -ansi -pedantic) The result
+#   is added to the shellvar being CFLAGS, CXXFLAGS, or FCFLAGS by default.
+#
+#   Currently this macro knows about the GCC, Solaris, Digital Unix, AIX,
+#   HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
+#   Intel compilers.  For a given compiler, the Fortran flags are much more
+#   experimental than their C equivalents.
+#

+#   AX_CONFIGURE_ARGS
+#
+# DESCRIPTION
+#
+#   Helper macro for AX_ENABLE_BUILDDIR.
+#
+#   The traditional way of starting a subdir-configure is running the script
+#   with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
+#   to rely on eval'ing $ac_configure_args however some old autoconf
+#   versions do not provide that. To ensure maximum portability of autoconf
+#   extension macros this helper can be AC_REQUIRE'd so that
+#   $ac_configure_args will alsways be present.
+#
+#   Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
+#   spoiled now and must be replaced by "eval + exit $?".
+#
+#   Example:

+# SYNOPSIS
+#
+#   AX_ENABLE_BUILDDIR [(dirstring-or-command [,Makefile.mk [,-all]])]
+#
+# DESCRIPTION
+#
+#   If the current configure was run within the srcdir then we move all
+#   configure-files into a subdir and let the configure steps continue
+#   there. We provide an option --disable-builddir to suppress the move into
+#   a separate builddir.
+#
+#   Defaults:
+#
+#     $1 = $host (overridden with $HOST)
+#     $2 = Makefile.mk
+#     $3 = -all
+#
+#   This macro must be called before AM_INIT_AUTOMAKE. It creates a default
+#   toplevel srcdir Makefile from the information found in the created
+#   toplevel builddir Makefile. It just copies the variables and
+#   rule-targets, each extended with a default rule-execution that recurses
+#   into the build directory of the current "HOST". You can override the
+#   auto-dection through `config.guess` and build-time of course, as in
+#
+#     make HOST=i386-mingw-cross
+#
+#   which can of course set at configure time as well using
+#
+#     configure --host=i386-mingw-cross
+#
+#   After the default has been created, additional rules can be appended
+#   that will not just recurse into the subdirectories and only ever exist
+#   in the srcdir toplevel makefile - these parts are read from the $2 =
+#   Makefile.mk file
+#
+#   The automatic rules are usually scanning the toplevel Makefile for lines
+#   like '#### $host |$builddir' to recognize the place where to recurse
+#   into. Usually, the last one is the only one used. However, almost all
+#   targets have an additional "*-all" rule which makes the script to
+#   recurse into _all_ variants of the current HOST (!!) setting. The "-all"
+#   suffix can be overriden for the macro as well.
+#
+#   a special rule is only given for things like "dist" that will copy the
+#   tarball from the builddir to the sourcedir (or $(PUB)) for reason of
+#   convenience.

+# SYNOPSIS
+#
+#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
+#
+# DESCRIPTION
+#
+#   This macro tries to guess the "native" arch corresponding to the target
+#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
+#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
+#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
+#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
+#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
+#
+#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
+#   the flag is set to -mtune (or equivalent) so that the architecture is
+#   only used for tuning, but the instruction set used is still portable. In
+#   the latter case, the flag is set to -march (or equivalent) so that
+#   architecture-specific instructions are enabled.
+#
+#   The user can specify --with-gcc-arch=<arch> in order to override the
+#   macro's choice of architecture, or --without-gcc-arch to disable this.
+#
+#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
+#   called unless the user specified --with-gcc-arch manually.
+#
+#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
+#
+#   (The main emphasis here is on recent CPUs, on the principle that doing
+#   high-performance computing on old hardware is uncommon.)

+#
+# SYNOPSIS
+#
+#   AX_GCC_X86_CPUID(OP)
+#
+# DESCRIPTION
+#
+#   On Pentium and later x86 processors, with gcc or a compiler that has a
+#   compatible syntax for inline assembly instructions, run a small program
+#   that executes the cpuid instruction with input OP. This can be used to
+#   detect the CPU type.
+#
+#   On output, the values of the eax, ebx, ecx, and edx registers are stored
+#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
+#   ax_cv_gcc_x86_cpuid_OP.
+#
+#   If the cpuid instruction fails (because you are running a
+#   cross-compiler, or because you are not using gcc, or because you are on
+#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
+#   is set to the string "unknown".
+#
+#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.

+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point

+.Fc
+.Sh DESCRIPTION
+The
+.Nm ffi_call
+function provides a simple mechanism for invoking a function without
+requiring knowledge of the function's interface at compile time.
+.Fa fn
+is called with the values retrieved from the pointers in the
+.Fa avalue
+array. The return value from
+.Fa fn
+is placed in storage pointed to by
+.Fa rvalue .
+.Fa cif
+contains information describing the data types, sizes and alignments of the
+arguments to and return value from
+.Fa fn ,
+and must be initialized with
+.Nm ffi_prep_cif
+before it is used with
+.Nm ffi_call .
+.Pp
+.Fa rvalue
+must point to storage that is sizeof(ffi_arg) or larger for non-floating point
+types. For smaller-sized return value types, the
+.Nm ffi_arg
+or
+.Nm ffi_sarg
+integral type must be used to hold
+the return value.

+  This is a version (aka dlmalloc) of malloc/free/realloc written by
+  Doug Lea and released to the public domain, as explained at
+  http://creativecommons.org/licenses/publicdomain.  Send questions,
+  comments, complaints, performance data, etc to dl at cs.oswego.edu
+
+* Version 2.8.3 Thu Sep 22 11:16:15 2005  Doug Lea  (dl at gee)
+
+   Note: There may be an updated version of this malloc obtainable at
+           ftp://gee.cs.oswego.edu/pub/misc/malloc.c
+         Check before installing!
+
+* Quickstart
+
+  This library is all in one file to simplify the most common usage:
+  ftp it, compile it (-O3), and link it into another program. All of
+  the compile-time options default to reasonable values for use on
+  most platforms.  You might later want to step through various
+  compile-time and dynamic tuning options.
+
+  For convenience, an include file for code using this malloc is at:
+     ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.3.h
+  You don't really need this .h file unless you call functions not
+  defined in your system include files.  The .h file contains only the
+  excerpts from this file needed for using this malloc on ANSI C/C++
+  systems, so long as you haven't changed compile-time options about
+  naming and tuning parameters.  If you do, then you can create your
+  own malloc.h that does include all settings by cutting at the point
+  indicated below. Note that you may already by default be using a C
+  library containing a malloc that is based on some version of this
+  malloc (for example in linux). You might still want to use the one
+  in this file to customize settings or to avoid overheads associated
+  with library versions.
+
+* Vital statistics:
+
+  Supported pointer/size_t representation:       4 or 8 bytes
+       size_t MUST be an unsigned type of the same width as
+       pointers. (If you are using an ancient system that declares
+       size_t as a signed type, or need it to be a different width
+       than pointers, you can use a previous release of this malloc
+       (e.g. 2.7.2) supporting these.)
+
+  Alignment:                                     8 bytes (default)
+       This suffices for nearly all current machines and C compilers.
+       However, you can define MALLOC_ALIGNMENT to be wider than this
+       if necessary (up to 128bytes), at the expense of using more space.
+
+  Minimum overhead per allocated chunk:   4 or  8 bytes (if 4byte sizes)
+                                          8 or 16 bytes (if 8byte sizes)
+       Each malloced chunk has a hidden word of overhead holding size
+       and status information, and additional cross-check word
+       if FOOTERS is defined.
+
+  Minimum allocated size: 4-byte ptrs:  16 bytes    (including overhead)
+                          8-byte ptrs:  32 bytes    (including overhead)
+
+       Even a request for zero bytes (i.e., malloc(0)) returns a
+       pointer to something of the minimum allocatable size.
+       The maximum overhead wastage (i.e., number of extra bytes
+       allocated than were requested in malloc) is less than or equal
+       to the minimum size, except for requests >= mmap_threshold that
+       are serviced via mmap(), where the worst case wastage is about
+       32 bytes plus the remainder from a system page (the minimal
+       mmap unit); typically 4096 or 8192 bytes.
+
+  Security: static-safe; optionally more or less
+       The "security" of malloc refers to the ability of malicious
+       code to accentuate the effects of errors (for example, freeing
+       space that is not currently malloc'ed or overwriting past the
+       ends of chunks) in code that calls malloc.  This malloc
+       guarantees not to modify any memory locations below the base of
+       heap, i.e., static variables, even in the presence of usage
+       errors.  The routines additionally detect most improper frees
+       and reallocs.  All this holds as long as the static bookkeeping
+       for malloc itself is not corrupted by some other means.  This
+       is only one aspect of security -- these checks do not, and
+       cannot, detect all possible programming errors.
+
+       If FOOTERS is defined nonzero, then each allocated chunk
+       carries an additional check word to verify that it was malloced
+       from its space.  These check words are the same within each
+       execution of a program using malloc, but differ across
+       executions, so externally crafted fake chunks cannot be
+       freed. This improves security by rejecting frees/reallocs that
+       could corrupt heap memory, in addition to the checks preventing
+       writes to statics that are always on.  This may further improve
+       security at the expense of time and space overhead.  (Note that
+       FOOTERS may also be worth using with MSPACES.)
+
+       By default detected errors cause the program to abort (calling
+       "abort()"). You can override this to instead proceed past
+       errors by defining PROCEED_ON_ERROR.  In this case, a bad free
+       has no effect, and a malloc that encounters a bad address
+       caused by user overwrites will ignore the bad address by
+       dropping pointers and indices to all known memory. This may
+       be appropriate for programs that should continue if at all
+       possible in the face of programming errors, although they may
+       run out of memory because dropped memory is never reclaimed.
+
+       If you don't like either of these options, you can define
+       CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
+       else. And if if you are sure that your program using malloc has
+       no errors or vulnerabilities, you can define INSECURE to 1,
+       which might (or might not) provide a small performance improvement.
+
+  Thread-safety: NOT thread-safe unless USE_LOCKS defined
+       When USE_LOCKS is defined, each public call to malloc, free,
+       etc is surrounded with either a pthread mutex or a win32
+       spinlock (depending on WIN32). This is not especially fast, and
+       can be a major bottleneck.  It is designed only to provide
+       minimal protection in concurrent environments, and to provide a
+       basis for extensions.  If you are using malloc in a concurrent
+       program, consider instead using ptmalloc, which is derived from
+       a version of this malloc. (See http://www.malloc.de).
+
+  System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
+       This malloc can use unix sbrk or any emulation (invoked using
+       the CALL_MORECORE macro) and/or mmap/munmap or any emulation
+       (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
+       memory.  On most unix systems, it tends to work best if both
+       MORECORE and MMAP are enabled.  On Win32, it uses emulations
+       based on VirtualAlloc. It also uses common C library functions
+       like memset.
+
+  Compliance: I believe it is compliant with the Single Unix Specification
+       (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
+       others as well.
+
+* Overview of algorithms
+
+  This is not the fastest, most space-conserving, most portable, or
+  most tunable malloc ever written. However it is among the fastest
+  while also being among the most space-conserving, portable and
+  tunable.  Consistent balance across these factors results in a good
+  general-purpose allocator for malloc-intensive programs.
+
+  In most ways, this malloc is a best-fit allocator. Generally, it
+  chooses the best-fitting existing chunk for a request, with ties
+  broken in approximately least-recently-used order. (This strategy
+  normally maintains low fragmentation.) However, for requests less
+  than 256bytes, it deviates from best-fit when there is not an
+  exactly fitting available chunk by preferring to use space adjacent
+  to that used for the previous small request, as well as by breaking
+  ties in approximately most-recently-used order. (These enhance
+  locality of series of small allocations.)  And for very large requests
+  (>= 256Kb by default), it relies on system memory mapping
+  facilities, if supported.  (This helps avoid carrying around and
+  possibly fragmenting memory used only for large chunks.)
+
+  All operations (except malloc_stats and mallinfo) have execution
+  times that are bounded by a constant factor of the number of bits in
+  a size_t, not counting any clearing in calloc or copying in realloc,
+  or actions surrounding MORECORE and MMAP that have times
+  proportional to the number of non-contiguous regions returned by
+  system allocation routines, which is often just 1.
+
+  The implementation is not very modular and seriously overuses
+  macros. Perhaps someday all C compilers will do as good a job
+  inlining modular code as can now be done by brute-force expansion,
+  but now, enough of them seem not to.
+
+  Some compilers issue a lot of warnings about code that is
+  dead/unreachable only on some platforms, and also about intentional
+  uses of negation on unsigned types. All known cases of each can be
+  ignored.
+
+  For a longer but out of date high-level description, see
+     http://gee.cs.oswego.edu/dl/html/malloc.html
+
+* MSPACES
+  If MSPACES is defined, then in addition to malloc, free, etc.,
+  this file also defines mspace_malloc, mspace_free, etc. These
+  are versions of malloc routines that take an "mspace" argument
+  obtained using create_mspace, to control all internal bookkeeping.
+  If ONLY_MSPACES is defined, only these versions are compiled.
+  So if you would like to use this allocator for only some allocations,
+  and your system malloc for others, you can compile with
+  ONLY_MSPACES and then do something like...
+    static mspace mymspace = create_mspace(0,0); // for example
+    #define mymalloc(bytes)  mspace_malloc(mymspace, bytes)
+
+  (Note: If you only need one instance of an mspace, you can instead
+  use "USE_DL_PREFIX" to relabel the global malloc.)
+
+  You can similarly create thread-local allocators by storing
+  mspaces as thread-locals. For example:
+    static __thread mspace tlms = 0;
+    void*  tlmalloc(size_t bytes) {
+      if (tlms == 0) tlms = create_mspace(0, 0);
+      return mspace_malloc(tlms, bytes);
+    }
+    void  tlfree(void* mem) { mspace_free(tlms, mem); }
+
+  Unless FOOTERS is defined, each mspace is completely independent.
+  You cannot allocate from one and free to another (although
+  conformance is only weakly checked, so usage errors are not always
+  caught). If FOOTERS is defined, then each chunk carries around a tag
+  indicating its originating mspace, and frees are directed to their
+  originating spaces.
+
+ -------------------------  Compile-time options ---------------------------
+
+Be careful in setting #define values for numerical constants of type
+size_t. On some systems, literal values are not automatically extended
+to size_t precision unless they are explicitly casted.
+
+WIN32                    default: defined if _WIN32 defined
+  Defining WIN32 sets up defaults for MS environment and compilers.
+  Otherwise defaults are for unix.
+
+MALLOC_ALIGNMENT         default: (size_t)8
+  Controls the minimum alignment for malloc'ed chunks.  It must be a
+  power of two and at least 8, even on machines for which smaller
+  alignments would suffice. It may be defined as larger than this
+  though. Note however that code and data structures are optimized for
+  the case of 8-byte alignment.
+
+MSPACES                  default: 0 (false)
+  If true, compile in support for independent allocation spaces.
+  This is only supported if HAVE_MMAP is true.
+
+ONLY_MSPACES             default: 0 (false)
+  If true, only compile in mspace versions, not regular versions.
+
+USE_LOCKS                default: 0 (false)
+  Causes each call to each public routine to be surrounded with
+  pthread or WIN32 mutex lock/unlock. (If set true, this can be
+  overridden on a per-mspace basis for mspace versions.)
+
+FOOTERS                  default: 0
+  If true, provide extra checking and dispatching by placing
+  information in the footers of allocated chunks. This adds
+  space and time overhead.
+
+INSECURE                 default: 0
+  If true, omit checks for usage errors and heap space overwrites.
+
+USE_DL_PREFIX            default: NOT defined
+  Causes compiler to prefix all public routines with the string 'dl'.
+  This can be useful when you only want to use this malloc in one part
+  of a program, using your regular system malloc elsewhere.
+
+ABORT                    default: defined as abort()
+  Defines how to abort on failed checks.  On most systems, a failed
+  check cannot die with an "assert" or even print an informative
+  message, because the underlying print routines in turn call malloc,
+  which will fail again.  Generally, the best policy is to simply call
+  abort(). It's not very useful to do more than this because many
+  errors due to overwriting will show up as address faults (null, odd
+  addresses etc) rather than malloc-triggered checks, so will also
+  abort.  Also, most compilers know that abort() does not return, so
+  can better optimize code conditionally calling it.
+
+PROCEED_ON_ERROR           default: defined as 0 (false)
+  Controls whether detected bad addresses cause them to bypassed
+  rather than aborting. If set, detected bad arguments to free and
+  realloc are ignored. And all bookkeeping information is zeroed out
+  upon a detected overwrite of freed heap space, thus losing the
+  ability to ever return it from malloc again, but enabling the
+  application to proceed. If PROCEED_ON_ERROR is defined, the
+  static variable malloc_corruption_error_count is compiled in
+  and can be examined to see if errors have occurred. This option
+  generates slower code than the default abort policy.
+
+DEBUG                    default: NOT defined
+  The DEBUG setting is mainly intended for people trying to modify
+  this code or diagnose problems when porting to new platforms.
+  However, it may also be able to better isolate user errors than just
+  using runtime checks.  The assertions in the check routines spell
+  out in more detail the assumptions and invariants underlying the
+  algorithms.  The checking is fairly extensive, and will slow down
+  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
+  set will attempt to check every non-mmapped allocated and free chunk
+  in the course of computing the summaries.
+
+ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
+  Debugging assertion failures can be nearly impossible if your
+  version of the assert macro causes malloc to be called, which will
+  lead to a cascade of further failures, blowing the runtime stack.
+  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
+  which will usually make debugging easier.
+
+MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
+  The action to take before "return 0" when malloc fails to be able to
+  return memory because there is none available.
+
+HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
+  True if this system supports sbrk or an emulation of it.
+
+MORECORE                  default: sbrk
+  The name of the sbrk-style system routine to call to obtain more
+  memory.  See below for guidance on writing custom MORECORE
+  functions. The type of the argument to sbrk/MORECORE varies across
+  systems.  It cannot be size_t, because it supports negative
+  arguments, so it is normally the signed type of the same width as
+  size_t (sometimes declared as "intptr_t").  It doesn't much matter
+  though. Internally, we only call it with arguments less than half
+  the max value of a size_t, which should work across all reasonable
+  possibilities, although sometimes generating compiler warnings.  See
+  near the end of this file for guidelines for creating a custom
+  version of MORECORE.
+
+MORECORE_CONTIGUOUS       default: 1 (true)
+  If true, take advantage of fact that consecutive calls to MORECORE
+  with positive arguments always return contiguous increasing
+  addresses.  This is true of unix sbrk. It does not hurt too much to
+  set it true anyway, since malloc copes with non-contiguities.
+  Setting it false when definitely non-contiguous saves time
+  and possibly wasted space it would take to discover this though.
+
+MORECORE_CANNOT_TRIM      default: NOT defined
+  True if MORECORE cannot release space back to the system when given
+  negative arguments. This is generally necessary only if you are
+  using a hand-crafted MORECORE function that cannot handle negative
+  arguments.
+
+HAVE_MMAP                 default: 1 (true)
+  True if this system supports mmap or an emulation of it.  If so, and
+  HAVE_MORECORE is not true, MMAP is used for all system
+  allocation. If set and HAVE_MORECORE is true as well, MMAP is
+  primarily used to directly allocate very large blocks. It is also
+  used as a backup strategy in cases where MORECORE fails to provide
+  space from system. Note: A single call to MUNMAP is assumed to be
+  able to unmap memory that may have be allocated using multiple calls
+  to MMAP, so long as they are adjacent.
+
+HAVE_MREMAP               default: 1 on linux, else 0
+  If true realloc() uses mremap() to re-allocate large blocks and
+  extend or shrink allocation spaces.
+
+MMAP_CLEARS               default: 1 on unix
+  True if mmap clears memory so calloc doesn't need to. This is true
+  for standard unix mmap using /dev/zero.
+
+USE_BUILTIN_FFS            default: 0 (i.e., not used)
+  Causes malloc to use the builtin ffs() function to compute indices.
+  Some compilers may recognize and intrinsify ffs to be faster than the
+  supplied C version. Also, the case of x86 using gcc is special-cased
+  to an asm instruction, so is already as fast as it can be, and so
+  this setting has no effect. (On most x86s, the asm version is only
+  slightly faster than the C version.)
+
+malloc_getpagesize         default: derive from system includes, or 4096.
+  The system page size. To the extent possible, this malloc manages
+  memory from the system in page-size units.  This may be (and
+  usually is) a function rather than a constant. This is ignored
+  if WIN32, where page size is determined using getSystemInfo during
+  initialization.
+
+USE_DEV_RANDOM             default: 0 (i.e., not used)
+  Causes malloc to use /dev/random to initialize secure magic seed for
+  stamping footers. Otherwise, the current time is used.
+
+NO_MALLINFO                default: 0
+  If defined, don't compile "mallinfo". This can be a simple way
+  of dealing with mismatches between system declarations and
+  those in this file.
+
+MALLINFO_FIELD_TYPE        default: size_t
+  The type of the fields in the mallinfo struct. This was originally
+  defined as "int" in SVID etc, but is more usefully defined as
+  size_t. The value is used only if  HAVE_USR_INCLUDE_MALLOC_H is not set
+
+REALLOC_ZERO_BYTES_FREES    default: not defined
+  This should be set if a call to realloc with zero bytes should 
+  be the same as a call to free. Some people think it should. Otherwise, 
+  since this malloc returns a unique pointer for malloc(0), so does 
+  realloc(p, 0).
+
+LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
+LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H,  LACKS_ERRNO_H
+LACKS_STDLIB_H                default: NOT defined unless on WIN32
+  Define these if your system does not have these header files.
+  You might need to manually insert some of the declarations they provide.
+
+DEFAULT_GRANULARITY        default: page size if MORECORE_CONTIGUOUS,
+                                system_info.dwAllocationGranularity in WIN32,
+                                otherwise 64K.
+      Also settable using mallopt(M_GRANULARITY, x)
+  The unit for allocating and deallocating memory from the system.  On
+  most systems with contiguous MORECORE, there is no reason to
+  make this more than a page. However, systems with MMAP tend to
+  either require or encourage larger granularities.  You can increase
+  this value to prevent system allocation functions to be called so
+  often, especially if they are slow.  The value must be at least one
+  page and must be a power of two.  Setting to 0 causes initialization
+  to either page size or win32 region size.  (Note: In previous
+  versions of malloc, the equivalent of this option was called
+  "TOP_PAD")
+
+DEFAULT_TRIM_THRESHOLD    default: 2MB
+      Also settable using mallopt(M_TRIM_THRESHOLD, x)
+  The maximum amount of unused top-most memory to keep before
+  releasing via malloc_trim in free().  Automatic trimming is mainly
+  useful in long-lived programs using contiguous MORECORE.  Because
+  trimming via sbrk can be slow on some systems, and can sometimes be
+  wasteful (in cases where programs immediately afterward allocate
+  more large chunks) the value should be high enough so that your
+  overall system performance would improve by releasing this much
+  memory.  As a rough guide, you might set to a value close to the
+  average size of a process (program) running on your system.
+  Releasing this much memory would allow such a process to run in
+  memory.  Generally, it is worth tuning trim thresholds when a
+  program undergoes phases where several large chunks are allocated
+  and released in ways that can reuse each other's storage, perhaps
+  mixed with phases where there are no such chunks at all. The trim
+  value must be greater than page size to have any useful effect.  To
+  disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
+  some people use of mallocing a huge space and then freeing it at
+  program startup, in an attempt to reserve system memory, doesn't
+  have the intended effect under automatic trimming, since that memory
+  will immediately be returned to the system.
+
+DEFAULT_MMAP_THRESHOLD       default: 256K
+      Also settable using mallopt(M_MMAP_THRESHOLD, x)
+  The request size threshold for using MMAP to directly service a
+  request. Requests of at least this size that cannot be allocated
+  using already-existing space will be serviced via mmap.  (If enough
+  normal freed space already exists it is used instead.)  Using mmap
+  segregates relatively large chunks of memory so that they can be
+  individually obtained and released from the host system. A request
+  serviced through mmap is never reused by any other request (at least
+  not directly; the system may just so happen to remap successive
+  requests to the same locations).  Segregating space in this way has
+  the benefits that: Mmapped space can always be individually released
+  back to the system, which helps keep the system level memory demands
+  of a long-lived program low.  Also, mapped memory doesn't become
+  `locked' between other chunks, as can happen with normally allocated
+  chunks, which means that even trimming via malloc_trim would not
+  release them.  However, it has the disadvantage that the space
+  cannot be reclaimed, consolidated, and then used to service later
+  requests, as happens with normal chunks.  The advantages of mmap
+  nearly always outweigh disadvantages for "large" chunks, but the
+  value of "large" may vary across systems.  The default is an
+  empirically derived value that works well in most systems. You can
+  disable mmap by setting to MAX_SIZE_T.

+  independent_calloc(size_t n_elements, size_t element_size, void* chunks[]);
+
+  independent_calloc is similar to calloc, but instead of returning a
+  single cleared space, it returns an array of pointers to n_elements
+  independent elements that can hold contents of size elem_size, each
+  of which starts out cleared, and can be independently freed,
+  realloc'ed etc. The elements are guaranteed to be adjacently
+  allocated (this is not guaranteed to occur with multiple callocs or
+  mallocs), which may also improve cache locality in some
+  applications.
+
+  The "chunks" argument is optional (i.e., may be null, which is
+  probably the most typical usage). If it is null, the returned array
+  is itself dynamically allocated and should also be freed when it is
+  no longer needed. Otherwise, the chunks array must be of at least
+  n_elements in length. It is filled in with the pointers to the
+  chunks.
+
+  In either case, independent_calloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and "chunks"
+  is null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use regular calloc and assign pointers into this
+  space to represent elements.  (In this case though, you cannot
+  independently free elements.)
+
+  independent_calloc simplifies and speeds up implementations of many
+  kinds of pools.  It may also be useful when constructing large data
+  structures that initially have a fixed number of fixed-sized nodes,
+  but the number is not known at compile time, and some of the nodes
+  may later need to be freed. For example:
+
+  struct Node { int item; struct Node* next; };
+
+  struct Node* build_list() {
+    struct Node** pool;
+    int n = read_number_of_nodes_needed();
+    if (n <= 0) return 0;
+    pool = (struct Node**)(independent_calloc(n, sizeof(struct Node), 0);
+    if (pool == 0) die();
+    // organize into a linked list...
+    struct Node* first = pool[0];
+    for (i = 0; i < n-1; ++i)
+      pool[i]->next = pool[i+1];
+    free(pool);     // Can now free the array (or not, if it is needed later)

+  independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]);
+
+  independent_comalloc allocates, all at once, a set of n_elements
+  chunks with sizes indicated in the "sizes" array.    It returns
+  an array of pointers to these elements, each of which can be
+  independently freed, realloc'ed etc. The elements are guaranteed to
+  be adjacently allocated (this is not guaranteed to occur with
+  multiple callocs or mallocs), which may also improve cache locality
+  in some applications.
+
+  The "chunks" argument is optional (i.e., may be null). If it is null
+  the returned array is itself dynamically allocated and should also
+  be freed when it is no longer needed. Otherwise, the chunks array
+  must be of at least n_elements in length. It is filled in with the
+  pointers to the chunks.
+
+  In either case, independent_comalloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and chunks is
+  null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use a single regular malloc, and assign pointers at
+  particular offsets in the aggregate space. (In this case though, you
+  cannot independently free elements.)
+
+  independent_comallac differs from independent_calloc in that each
+  element may have a different size, and also that it does not
+  automatically clear elements.
+
+  independent_comalloc can be used to speed up allocation in cases
+  where several structs or objects must always be allocated at the
+  same time.  For example:
+
+  struct Head { ... }
+  struct Foot { ... }
+
+  void send_message(char* msg) {
+    int msglen = strlen(msg);
+    size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };

+    char*        body = (char*)(chunks[1]);
+    struct Foot* foot = (struct Foot*)(chunks[2]);
+    // ...
+  }
+
+  In general though, independent_comalloc is worth using only for
+  larger values of n_elements. For small values, you probably won't
+  detect enough difference from series of malloc calls to bother.
+
+  Overuse of independent_comalloc can increase overall memory usage,
+  since it cannot reuse existing noncontiguous small chunks that
+  might be available for some of the elements.

+/*
+  (The following includes lightly edited explanations by Colin Plumb.)
+
+  The malloc_chunk declaration below is misleading (but accurate and
+  necessary).  It declares a "view" into memory allowing access to
+  necessary fields at known offsets from a given base.
+
+  Chunks of memory are maintained using a `boundary tag' method as
+  originally described by Knuth.  (See the paper by Paul Wilson
+  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
+  techniques.)  Sizes of free chunks are stored both in the front of
+  each chunk and at the end.  This makes consolidating fragmented
+  chunks into bigger chunks fast.  The head fields also hold bits
+  representing whether chunks are free or in use.
+
+  Here are some pictures to make it clearer.  They are "exploded" to
+  show that the state of a chunk can be thought of as extending from
+  the high 31 bits of the head field of its header through the
+  prev_foot and PINUSE_BIT bit of the following chunk header.
+
+  A chunk that's in use looks like:
+
+   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+           | Size of previous chunk (if P = 1)                             |

+         +-                                                             -+

+  Note that since we always merge adjacent free chunks, the chunks
+  adjacent to a free chunk must be in use.
+
+  Given a pointer to a chunk (which can be derived trivially from the
+  payload pointer) we can, in O(1) time, find out whether the adjacent
+  chunks are free, and if so, unlink them from the lists that they
+  are on and merge them with the current chunk.
+
+  Chunks always begin on even word boundaries, so the mem portion
+  (which is returned to the user) is also on an even word boundary, and
+  thus at least double-word aligned.
+
+  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
+  chunk size (which is always a multiple of two words), is an in-use
+  bit for the *previous* chunk.  If that bit is *clear*, then the
+  word before the current chunk size contains the previous chunk
+  size, and can be used to find the front of the previous chunk.
+  The very first chunk allocated always has this bit set, preventing
+  access to non-existent (or non-owned) memory. If pinuse is set for
+  any given chunk, then you CANNOT determine the size of the
+  previous chunk, and might even get a memory addressing fault when
+  trying to do so.
+
+  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
+  the chunk size redundantly records whether the current chunk is
+  inuse. This redundancy enables usage checks within free and realloc,
+  and reduces indirection when freeing and consolidating chunks.
+
+  Each freshly allocated chunk must have both cinuse and pinuse set.
+  That is, each allocated chunk borders either a previously allocated
+  and still in-use chunk, or the base of its memory arena. This is
+  ensured by making all allocations from the the `lowest' part of any
+  found chunk.  Further, no free chunk physically borders another one,
+  so each free chunk is known to be preceded and followed by either
+  inuse chunks or the ends of memory.
+
+  Note that the `foot' of the current chunk is actually represented
+  as the prev_foot of the NEXT chunk. This makes it easier to
+  deal with alignments etc but can be very confusing when trying
+  to extend or adapt this code.
+
+  The exceptions to all this are
+
+     1. The special chunk `top' is the top-most available chunk (i.e.,
+        the one bordering the end of available memory). It is treated
+        specially.  Top is never included in any bin, is used only if
+        no other chunk is available, and is released back to the
+        system if it is very large (see M_TRIM_THRESHOLD).  In effect,
+        the top chunk is treated as larger (and thus less well
+        fitting) than any other available chunk.  The top chunk
+        doesn't update its trailing size field since there is no next
+        contiguous chunk that would have to index off it. However,
+        space is still allocated for it (TOP_FOOT_SIZE) to enable
+        separation or merging when space is extended.
+
+     3. Chunks allocated via mmap, which have the lowest-order bit
+        (IS_MMAPPED_BIT) set in their prev_foot fields, and do not set
+        PINUSE_BIT in their head fields.  Because they are allocated
+        one-by-one, each must carry its own prev_foot field, which is
+        also used to hold the offset this chunk has within its mmapped
+        region, which is needed to preserve alignment. Each mmapped
+        chunk is trailed by the first two fields of a fake next-chunk
+        for sake of usage checks.

+
+  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
+  of the same size are arranged in a circularly-linked list, with only
+  the oldest chunk (the next to be used, in our FIFO ordering)
+  actually in the tree.  (Tree members are distinguished by a non-null
+  parent pointer.)  If a chunk with the same size an an existing node
+  is inserted, it is linked off the existing node using pointers that
+  work in the same way as fd/bk pointers of small chunks.
+
+  Each tree contains a power of 2 sized range of chunk sizes (the
+  smallest is 0x100 <= x < 0x180), which is is divided in half at each
+  tree level, with the chunks in the smaller half of the range (0x100
+  <= x < 0x140 for the top nose) in the left subtree and the larger
+  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
+  done by inspecting individual bits.
+
+  Using these rules, each node's left subtree contains all smaller
+  sizes than its right subtree.  However, the node at the root of each
+  subtree has no particular ordering relationship to either.  (The
+  dividing line between the subtree sizes is based on trie relation.)
+  If we remove the last chunk of a given size from the interior of the
+  tree, we need to replace it with a leaf node.  The tree ordering
+  rules permit a node to be replaced by any leaf below it.
+
+  The smallest chunk in a tree (a common operation in a best-fit
+  allocator) can be found by walking a path to the leftmost leaf in
+  the tree.  Unlike a usual binary tree, where we follow left child
+  pointers until we reach a null, here we follow the right child
+  pointer any time the left one is null, until we reach a leaf with
+  both child pointers null. The smallest chunk in the tree will be
+  somewhere along that path.
+
+  The worst case number of steps to add, find, or remove a node is
+  bounded by the number of bits differentiating chunks within
+  bins. Under current bin calculations, this ranges from 6 up to 21
+  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
+  is of course much better.

+/* ----------------------------- Segments -------------------------------- */
+
+/*
+  Each malloc space may include non-contiguous segments, held in a
+  list headed by an embedded malloc_segment record representing the
+  top-most space. Segments also include flags holding properties of
+  the space. Large chunks that are directly allocated by mmap are not
+  included in this list. They are instead independently created and
+  destroyed without otherwise keeping track of them.
+
+  Segment management mainly comes into play for spaces allocated by
+  MMAP.  Any call to MMAP might or might not return memory that is
+  adjacent to an existing segment.  MORECORE normally contiguously
+  extends the current space, so this space is almost always adjacent,
+  which is simpler and faster to deal with. (This is why MORECORE is
+  used preferentially to MMAP when both are available -- see
+  sys_alloc.)  When allocating using MMAP, we don't use any of the
+  hinting mechanisms (inconsistently) supported in various
+  implementations of unix mmap, or distinguish reserving from
+  committing memory. Instead, we just ask for space, and exploit
+  contiguity when we get it.  It is probably possible to do
+  better than this on some systems, but no general scheme seems
+  to be significantly better.
+
+  Management entails a simpler variant of the consolidation scheme
+  used for chunks to reduce fragmentation -- new adjacent memory is
+  normally prepended or appended to an existing segment. However,
+  there are limitations compared to chunk consolidation that mostly
+  reflect the fact that segment processing is relatively infrequent
+  (occurring only when getting memory from system) and that we
+  don't expect to have huge numbers of segments:
+
+  * Segments are not indexed, so traversal requires linear scans.  (It
+    would be possible to index these, but is not worth the extra
+    overhead and complexity for most programs on most platforms.)
+  * New segments are only appended to old ones when holding top-most
+    memory; if they cannot be prepended to others, they are held in
+    different segments.
+
+  Except for the top-most segment of an mstate, each segment record
+  is kept at the tail of its segment. Segments are added by pushing
+  segment records onto the list headed by &mstate.seg for the
+  containing mstate.
+
+  Segment flags control allocation/merge/deallocation policies:
+  * If EXTERN_BIT set, then we did not allocate this segment,
+    and so should not try to deallocate or merge with others.
+    (This currently holds only for the initial segment passed
+    into create_mspace_with_base.)
+  * If IS_MMAPPED_BIT set, the segment may be merged with
+    other surrounding mmapped segments and trimmed/de-allocated
+    using munmap.
+  * If neither bit is set, then the segment was obtained using
+    MORECORE so can be merged with surrounding MORECORE'd segments
+    and deallocated/trimmed using MORECORE with negative arguments.

+   A malloc_state holds all of the bookkeeping for a space.
+   The main fields are:
+
+  Top
+    The topmost chunk of the currently active segment. Its size is
+    cached in topsize.  The actual size of topmost space is
+    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
+    fenceposts and segment records if necessary when getting more
+    space from the system.  The size at which to autotrim top is
+    cached from mparams in trim_check, except that it is disabled if
+    an autotrim fails.
+
+  Designated victim (dv)
+    This is the preferred chunk for servicing small requests that
+    don't have exact fits.  It is normally the chunk split off most
+    recently to service another small request.  Its size is cached in
+    dvsize. The link fields of this chunk are not maintained since it
+    is not kept in a bin.
+
+  SmallBins
+    An array of bin headers for free chunks.  These bins hold chunks
+    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+    chunks of all the same size, spaced 8 bytes apart.  To simplify
+    use in double-linked lists, each bin header acts as a malloc_chunk
+    pointing to the real first node, if it exists (else pointing to
+    itself).  This avoids special-casing for headers.  But to avoid
+    waste, we allocate only the fd/bk pointers of bins, and then use
+    repositioning tricks to treat these as the fields of a chunk.
+
+  TreeBins
+    Treebins are pointers to the roots of trees holding a range of
+    sizes. There are 2 equally spaced treebins for each power of two
+    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+    larger.
+
+  Bin maps
+    There is one bit map for small bins ("smallmap") and one for
+    treebins ("treemap).  Each bin sets its bit when non-empty, and
+    clears the bit when empty.  Bit operations are then used to avoid
+    bin-by-bin searching -- nearly all "search" is done without ever
+    looking at bins that won't be selected.  The bit maps
+    conservatively use 32 bits per map word, even if on 64bit system.
+    For a good description of some of the bit-based techniques used
+    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+    supplement at http://hackersdelight.org/). Many of these are
+    intended to reduce the branchiness of paths through malloc etc, as
+    well as to reduce the number of memory locations read or written.
+
+  Segments
+    A list of segments headed by an embedded malloc_segment record
+    representing the initial space.
+
+  Address check support
+    The least_addr field is the least address ever obtained from
+    MORECORE or MMAP. Attempted frees and reallocs of any address less
+    than this are trapped (unless INSECURE is defined).
+
+  Magic tag
+    A cross-check field that should always hold same value as mparams.magic.
+
+  Flags
+    Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+  Statistics
+    Each space keeps track of current and maximum system memory
+    obtained via MORECORE or MMAP.
+
+  Locking
+    If USE_LOCKS is defined, the "mutex" lock is acquired and released
+    around every public call using this mspace.

+  For security, the main invariant is that malloc/free/etc never
+  writes to a static address other than malloc_state, unless static
+  malloc_state itself has been corrupted, which cannot occur via
+  malloc (because of these checks). In essence this means that we
+  believe all pointers, sizes, maps etc held in malloc_state, but
+  check all of those linked or offsetted from other embedded data
+  structures.  These checks are interspersed with main code in a way
+  that tends to minimize their run-time cost.
+
+  When FOOTERS is defined, in addition to range checking, we also
+  verify footer fields of inuse chunks, which can be used guarantee
+  that the mstate controlling malloc/free is intact.  This is a
+  streamlined version of the approach described by William Robertson
+  et al in "Run-time Detection of Heap-based Overflows" LISA'03
+  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
+  of an inuse chunk holds the xor of its mstate and a random seed,
+  that is checked upon calls to free() and realloc().  This is
+  (probablistically) unguessable from outside the program, but can be
+  computed by any code successfully malloc'ing any chunk, so does not
+  itself provide protection against code that has already broken
+  security through some other means.  Unlike Robertson et al, we
+  always dynamically check addresses of all offset chunks (previous,
+  next, etc). This turns out to be cheaper than relying on hashes.

+/* -------------------- Alternative MORECORE functions ------------------- */
+
+/*
+  Guidelines for creating a custom version of MORECORE:
+
+  * For best performance, MORECORE should allocate in multiples of pagesize.
+  * MORECORE may allocate more memory than requested. (Or even less,
+      but this will usually result in a malloc failure.)
+  * MORECORE must not allocate memory when given argument zero, but
+      instead return one past the end address of memory from previous
+      nonzero call.
+  * For best performance, consecutive calls to MORECORE with positive
+      arguments should return increasing addresses, indicating that
+      space has been contiguously extended.
+  * Even though consecutive calls to MORECORE need not return contiguous
+      addresses, it must be OK for malloc'ed chunks to span multiple
+      regions in those cases where they do happen to be contiguous.
+  * MORECORE need not handle negative arguments -- it may instead
+      just return MFAIL when given negative arguments.
+      Negative arguments are always multiples of pagesize. MORECORE
+      must not misinterpret negative args as large positive unsigned
+      args. You can suppress all such calls from even occurring by defining
+      MORECORE_CANNOT_TRIM,
+
+  As an example alternative MORECORE, here is a custom allocator
+  kindly contributed for pre-OSX macOS.  It uses virtually but not
+  necessarily physically contiguous non-paged memory (locked in,
+  present and won't get swapped out).  You can use it by uncommenting
+  this section, adding some #includes, and setting up the appropriate
+  defines above:
+
+      #define MORECORE osMoreCore
+
+  There is also a shutdown routine that should somehow be called for
+  cleanup upon program exit.
+
+  #define MAX_POOL_ENTRIES 100
+  #define MINIMUM_MORECORE_SIZE  (64 * 1024U)
+  static int next_os_pool;
+  void *our_os_pools[MAX_POOL_ENTRIES];
+
+  void *osMoreCore(int size)
+  {
+    void *ptr = 0;
+    static void *sbrk_top = 0;
+
+    if (size > 0)
+    {
+      if (size < MINIMUM_MORECORE_SIZE)
+         size = MINIMUM_MORECORE_SIZE;
+      if (CurrentExecutionLevel() == kTaskLevel)
+         ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0);
+      if (ptr == 0)
+      {
+        return (void *) MFAIL;
+      }
+      // save ptrs so they can be freed during cleanup
+      our_os_pools[next_os_pool] = ptr;
+      next_os_pool++;
+      ptr = (void *) ((((size_t) ptr) + RM_PAGE_MASK) & ~RM_PAGE_MASK);
+      sbrk_top = (char *) ptr + size;
+      return ptr;
+    }
+    else if (size < 0)
+    {
+      // we don't currently support shrink behavior
+      return (void *) MFAIL;

+      * Integrated most documentation with the code.
+      * Add support for mmap, with help from
+        Wolfram Gloger (Gloger at lrz.uni-muenchen.de).

+      * Inverted this history list
+
+    V2.6.1 Sat Dec  2 14:10:57 1995  Doug Lea  (dl at gee)
+      * Re-tuned and fixed to behave more nicely with V2.6.0 changes.
+      * Removed all preallocation code since under current scheme
+        the work required to undo bad preallocations exceeds
+        the work saved in good cases for most test programs.
+      * No longer use return list or unconsolidated bins since

+
+    V2.5.2 Tue Apr  5 16:20:40 1994  Doug Lea  (dl at g)
+      * realloc: try to expand in both directions
+      * malloc: swap order of clean-bin strategy;
+      * realloc: only conditionally expand backwards
+      * Try not to scavenge used bins
+      * Use bin counts as a guide to preallocation
+      * Occasionally bin return list chunks in first scan
+      * Add a few optimizations from colin at nyx10.cs.du.edu
+
+    V2.5.1 Sat Aug 14 15:40:43 1993  Doug Lea  (dl at g)
+      * faster bin computation & slightly different binning
+      * merged all consolidations to one part of malloc proper
+         (eliminating old malloc_find_space & malloc_clean_bin)
+      * Scan 2 returns chunks (not just 1)
+      * Propagate failure in realloc if malloc returns 0
+      * Add stuff to allow compilation on non-ANSI compilers

+      * tested on sparc, hp-700, dec-mips, rs6000
+          with gcc & native cc (hp, dec only) allowing
+          Detlefs & Zorn comparison study (in SIGPLAN Notices.)
+
+    Trial version Fri Aug 28 13:14:29 1992  Doug Lea  (dl at g.oswego.edu)
+      * Based loosely on libg++-1.2X malloc. (It retains some of the overall
+         structure of old version,  but most details differ.)

+   the first four argument slots.  Non FP arguments are passed solely
+   in the general registers.  FP arguments are passed in both general
+   and floating registers when using libffi.
+
+   Non-FP 32-bit args are passed in gr26, gr25, gr24 and gr23.
+   Non-FP 64-bit args are passed in register pairs, starting
+   on an odd numbered register (i.e. r25+r26 and r23+r24).
+   FP 32-bit arguments are passed in fr4L, fr5L, fr6L and fr7L.
+   FP 64-bit arguments are passed in fr5 and fr7.
+
+   The registers are allocated in the same manner as stack slots.
+   This allows the callee to save its arguments on the stack if
+   necessary:
+
+   arg word 3 -> gr23 or fr7L
+   arg word 2 -> gr24 or fr6L or fr7R
+   arg word 1 -> gr25 or fr5L
+   arg word 0 -> gr26 or fr4L or fr5R
+
+   Note that fr4R and fr6R are never used for arguments (i.e.,
+   doubles are not passed in fr4 or fr6).
+
+   The rest of the arguments are passed on the stack starting at SP-52,
+   but 64-bit arguments need to be aligned to an 8-byte boundary
+
+   This means we can have holes either in the register allocation,

+%
+% As a special exception, when this file is read by TeX when processing
+% a Texinfo source document, you may use the result without
+% restriction.  (This has been our intent since Texinfo was invented.)
+%
+% Please try the latest version of texinfo.tex before submitting bug
+% reports; you can get the latest version from:
+%   http://www.gnu.org/software/texinfo/ (the Texinfo home page), or
+%   ftp://tug.org/tex/texinfo.tex
+%     (and all CTAN mirrors, see http://www.ctan.org).
+% The texinfo.tex in any given distribution could well be out
+% of date, so if that's what you're using, please check.
+%
+% Send bug reports to bug-texinfo at gnu.org.  Please include including a
+% complete document in each bug report with which we can reproduce the
+% problem.  Patches are, of course, greatly appreciated.
+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent.  You can get the existing language-specific files from the
+% full Texinfo distribution.
+%
+% The GNU Texinfo home page is http://www.gnu.org/software/texinfo.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab at tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item at tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+FAQ
+===
+
+**But I still don't understand why I should care?**
+
+As mentioned earlier, persistent data structures perform a
+copy whenever they are modified meaning there is never any
+chance that two threads could be modifying the same instance
+at any one time. And, because they are very efficient copies,
+you don't need to worry about using up gobs of memory in the
+process.
+
+Even if threading isn't a concern, because they're immutable,
+you can pass them around between objects, methods, and
+functions in the same thread and never worry about data
+corruption; no more defensive calls to `Object#dup`!
+
+
+**What's the downside--there's always a downside?**
+
+There's a potential performance hit when compared with MRI's
+built-in, native, hand-crafted C-code implementation of Hash.
+
+For example:
+
+``` ruby
+hash = Hamster::Hash.empty
+(1..10000).each { |i| hash = hash.put(i, i) }
+  # => 0.05s
+(1..10000).each { |i| hash.get(i) }
+  # => 0.008s
+```
+
+vs.
+
+``` ruby
+hash = {}
+(1..10000).each { |i| hash[i] = i }
+  # => 0.004s
+(1..10000).each { |i| hash[i] }
+  # => 0.001s
+```
+
+The previous comparison wasn't really fair. Sure, if all you
+want to do is replace your existing uses of `Hash` in single-
+threaded environments then don't even bother. However, if you
+need something that can be used efficiently in concurrent
+environments where multiple threads are accessing--reading AND
+writing--the contents things get much better.
+
+A more realistic comparison might look like:
+
+``` ruby
+hash = Hamster::Hash.empty
+(1..10000).each { |i| hash = hash.put(i, i) }
+  # => 0.05s
+(1..10000).each { |i| hash.get(i) }
+  # => 0.008s
+```
+
+versus
+
+``` ruby
+hash = {}
+(1..10000).each { |i| hash = hash.dup; hash[i] = i }
+  # => 19.8s
+
+(1..10000).each { |i| hash[i] }
+  # => 0.001s
+```
+
+What's even better -- or worse depending on your perspective
+-- is that after all that, the native `Hash` version still
+isn't thread-safe and still requires some synchronization
+around it slowing it down even further.
+
+The Hamster version on the other hand was unchanged from the
+original whilst remaining inherently thread-safe, and 3 orders
+of magnitude faster.
+
+**You still need synchronisation so why bother with the copying?**
+
+Well, I could show you one but I'd have to re-write/wrap most
+Hash methods to make them generic, or at the very least write
+some application-specific code that synchronized using a `
+Mutex` and ... well ... it's hard, I always make mistakes,
+I always end up with weird edge cases and race conditions so,
+I'll leave that as an exercise for you :)
+
+And don't forget that even if threading isn't a concern for
+you, the safety provided by immutability alone is worth it,
+not to mention the lazy implementations.

+
+Efficient, immutable, and thread-safe collection classes for Ruby.
+
+Hamster provides 6 [Persistent Data
+Structures][PDS]: [`Hash`][HASH-DOC], [`Vector`][VECTOR-DOC], [`Set`][SET-DOC], [`SortedSet`][SORTED-SET-DOC], [`List`][LIST-DOC], and [`Deque`][DEQUE-DOC] (which works as an immutable queue or stack).
+
+Hamster collections are **immutable**. Whenever you modify a Hamster
+collection, the original is preserved and a modified copy is returned. This
+makes them inherently thread-safe and shareable. At the same time, they remain
+CPU and memory-efficient by sharing between copies. 
+
+While Hamster collections are immutable, you can still mutate objects stored
+in them. We recommend that  you don't do this, unless you are sure you know 
+what you are doing. Hamster collections are thread-safe and can be freely 
+shared between threads, but you are responsible for making sure that the 
+objects stored in them are used in a thread-safe manner.
+
+Hamster collections are almost always closed under a given operation. That is,
+whereas Ruby's collection methods always return arrays, Hamster collections
+will return an instance of the same class wherever possible.
+
+Where possible, Hamster collections offer an interface compatible with Ruby's
+built-in `Hash`, `Array`, and `Enumerable`, to ease code migration. Also, Hamster methods accept regular Ruby collections as arguments, so code which uses `Hamster` can easily interoperate with your other Ruby code.
+
+And lastly, Hamster lists are lazy, making it possible to (among other things)
+process "infinitely large" lists.

+
+Using
+=====
+
+To make the collection classes available in your code:
+
+``` ruby
+require "hamster"
+```
+
+Or if you prefer to only pull in certain collection types:
+
+``` ruby
+require "hamster/hash"
+require "hamster/vector"
+require "hamster/set"
+require "hamster/sorted_set"
+require "hamster/list"
+require "hamster/deque"
+```
+
+<h2>Hash <span style="font-size:0.7em">(<a href="http://rubydoc.info/github/hamstergem/hamster/master/Hamster/Hash">API Documentation</a>)</span></h2>
+
+Constructing a Hamster `Hash` is almost as simple as a regular one:
+
+``` ruby
+person = Hamster::Hash[name: "Simon", gender: :male]
+# => Hamster::Hash[:name => "Simon", :gender => :male]
+```
+
+Accessing the contents will be familiar to you:
+
+``` ruby
+person[:name]                       # => "Simon"
+person.get(:gender)                 # => :male
+```
+
+Updating the contents is a little different than you are used to:
+
+``` ruby
+friend = person.put(:name, "James") # => Hamster::Hash[:name => "James", :gender => :male]
+person                              # => Hamster::Hash[:name => "Simon", :gender => :male]
+friend[:name]                       # => "James"
+person[:name]                       # => "Simon"
+```
+
+As you can see, updating the hash returned a copy leaving
+the original intact. Similarly, deleting a key returns
+yet another copy:
+
+``` ruby
+male = person.delete(:name)         # => Hamster::Hash[:gender => :male]
+person                              # => Hamster::Hash[:name => "Simon", :gender => :male]
+male.key?(:name)                    # => false
+person.key?(:name)                  # => true
+```
+
+Since it is immutable, Hamster's `Hash` doesn't provide an assignment
+(`Hash#[]=`) method. However, `Hash#put` can accept a block which
+transforms the value associated with a given key:
+
+``` ruby
+counters.put(:odds) { |value| value + 1 } # => Hamster::Hash[:odds => 1, :evens => 0]
+```
+
+Or more succinctly:
+
+``` ruby
+counters.put(:odds, &:next)         # => {:odds => 1, :evens => 0}
+```
+
+This is just the beginning; see the [API documentation][HASH-DOC] for details on all `Hash` methods.
+
+
+<h2>Vector <span style="font-size:0.7em">(<a href="http://rubydoc.info/github/hamstergem/hamster/master/Hamster/Vector">API Documentation</a>)</span></h2>
+
+A `Vector` is an integer-indexed collection much like an immutable `Array`. Examples:
+
+``` ruby
+vector = Hamster::Vector[1, 2, 3, 4] # => Hamster::Vector[1, 2, 3, 4]
+vector[0]                            # => 1
+vector[-1]                           # => 4
+vector.put(1, :a)                    # => Hamster::Vector[1, :a, 3, 4]
+vector.add(:b)                       # => Hamster::Vector[1, 2, 3, 4, :b]
+vector.insert(2, :a, :b)             # => Hamster::Vector[1, 2, :a, :b, 3, 4]
+vector.delete_at(0)                  # => Hamster::Vector[2, 3, 4]
+```
+
+Other `Array`-like methods like `#select`, `#map`, `#shuffle`, `#uniq`, `#reverse`,
+`#rotate`, `#flatten`, `#sort`, `#sort_by`, `#take`, `#drop`, `#take_while`,
+`#drop_while`, `#fill`, `#product`, and `#transpose` are also supported. See the
+[API documentation][VECTOR-DOC] for details on all `Vector` methods.
+
+
+<h2>Set <span style="font-size:0.7em">(<a href="http://rubydoc.info/github/hamstergem/hamster/master/Hamster/Set">API Documentation</a>)</span></h2>
+
+A `Set` is an unordered collection of values with no duplicates. It is much like the Ruby standard library's `Set`, but immutable. Examples:
+
+``` ruby
+set = Hamster::Set[:red, :blue, :yellow] # => Hamster::Set[:red, :blue, :yellow]
+set.include? :red                        # => true
+set.add :green                           # => Hamster::Set[:red, :blue, :yellow, :green]
+set.delete :blue                         # => Hamster::Set[:red, :yellow]
+set.superset? Hamster::Set[:red, :blue]  # => true
+set.union([:red, :blue, :pink])          # => Hamster::Set[:red, :blue, :yellow, :pink]
+set.intersection([:red, :blue, :pink])   # => Hamster::Set[:red, :blue]
+```
+
+Like most Hamster methods, the set-theoretic methods `#union`, `#intersection`, `#difference`, and `#exclusion` (aliased as `#|`, `#&`, `#-`, and `#^`) all work with regular Ruby collections, or indeed any `Enumerable` object. So just like all the other Hamster collections, `Hamster::Set` can easily be used in combination with "ordinary" Ruby code.
+
+See the [API documentation][SET-DOC] for details on all `Set` methods.
+
+
+<h2>SortedSet <span style="font-size:0.7em">(<a href="http://rubydoc.info/github/hamstergem/hamster/master/Hamster/SortedSet">API Documentation</a>)</span></h2>
+
+A `SortedSet` is like a `Set`, but ordered. You can do everything with it that you can
+do with a `Set`. Additionally, you can get the `#first` and `#last` item, or retrieve
+an item using an integral index:
+
+``` ruby
+set = Hamster::SortedSet['toast', 'jam', 'bacon'] # => Hamster::SortedSet["bacon", "jam", "toast"]
+set.first                                         # => "bacon"
+set.last                                          # => "toast"
+set[1]                                            # => "jam"
+```
+
+You can also specify the sort order using a block:
+
+``` ruby
+Hamster::SortedSet.new(['toast', 'jam', 'bacon']) { |a,b| b <=> a }
+Hamster::SortedSet.new(['toast', 'jam', 'bacon']) { |str| str.chars.last }
+```
+
+See the [API documentation][SORTED-SET-DOC] for details on all `SortedSet` methods.
+
+
+<h2>List <span style="font-size:0.7em">(<a href="http://rubydoc.info/github/hamstergem/hamster/master/Hamster/List">API Documentation</a>)</span></h2>
+
+Hamster `List`s have a *head* (the value at the front of the list),
+and a *tail* (a list of the remaining items):
+
+``` ruby
+list = Hamster::List[1, 2, 3]
+list.head                    # => 1
+list.tail                    # => Hamster::List[2, 3]
+```
+
+Add to a list with `List#add`:
+
+``` ruby
+original = Hamster::List[1, 2, 3]
+copy = original.add(0)      # => Hamster::List[0, 1, 2, 3]
+```
+
+Notice how modifying a list actually returns a new list.
+That's because Hamster `List`s are immutable.
+
+### Laziness
+
+`List` is lazy where possible. It tries to defer processing items until
+absolutely necessary. For example, given a crude function to detect prime
+numbers:
+
+``` ruby
+def prime?(number)
+  2.upto(Math.sqrt(number).round) do |integer|
+    return false if (number % integer).zero?
+  end
+  true
+end
+```
+
+The following code will only call `#prime?` as many times as
+necessary to generate the first 3 prime numbers between 10,000
+and 1,000,000:
+
+``` ruby
+Hamster.interval(10_000, 1_000_000).select do |number|
+  prime?(number)
+end.take(3)
+  # => 0.0009s
+```
+
+Compare that to the conventional equivalent which needs to
+calculate all possible values in the range before taking the
+first three:
+
+``` ruby
+(10000..1000000).select do |number|
+  prime?(number)
+end.take(3)
+  # => 10s
+```
+
+### Construction
+
+Besides `Hamster::List[]` there are other ways to construct lists:
+
+  - `Hamster.interval(from, to)` creates a lazy list
+    equivalent to a list containing all the values between
+    `from` and `to` without actually creating a list that big.
+
+  - `Hamster.stream { ... }` allows you to creates infinite
+    lists. Each time a new value is required, the supplied
+    block is called. To generate a list of integers you
+    could do:
+
+    ``` ruby
+    count = 0
+    Hamster.stream { count += 1 }
+    ```
+
+  - `Hamster.repeat(x)` creates an infinite list with `x` the
+    value for every element.
+
+  - `Hamster.replicate(n, x)` creates a list of size `n` with
+    `x` the value for every element.
+
+  - `Hamster.iterate(x) { |x| ... }` creates an infinite
+    list where the first item is calculated by applying the
+    block on the initial argument, the second item by applying
+    the function on the previous result and so on. For
+    example, a simpler way to generate a list of integers
+    would be:
+
+    ``` ruby
+    Hamster.iterate(1) { |i| i + 1 }
+    ```
+
+    or even more succinctly:
+
+    ``` ruby
+    Hamster.iterate(1, &:next)
+    ```
+
+  - `Hamster::List.empty` returns an empty list, which you can
+    build up using repeated calls to `#add` or other `List` methods.
+
+### Core Extensions
+
+`Enumerable#to_list` will convert any existing `Enumerable` to a list, so you can
+slowly transition from built-in collection classes to Hamster.
+
+`IO#to_list` enables lazy processing of huge files. For example, imagine the
+following code to process a 100MB file:
+
+``` ruby
+require 'hamster/core_ext'
+
+File.open("my_100_mb_file.txt") do |file|
+  lines = []
+  file.each_line do |line|
+    break if lines.size == 10
+    lines << line.chomp.downcase.reverse
+  end
+end
+```
+
+Compare to the following more functional version:
+
+``` ruby
+File.open("my_100_mb_file.txt") do |file|
+  file.map(&:chomp).map(&:downcase).map(&:reverse).take(10)
+end
+```
+
+Unfortunately, though the second example reads nicely it
+takes many seconds to run (compared with milliseconds
+for the first) even though we're only interested in the first
+ten lines. Using `#to_list` we can get the running time back comparable to the
+imperative version.
+
+``` ruby
+File.open("my_100_mb_file.txt") do |file|
+  file.to_list.map(&:chomp).map(&:downcase).map(&:reverse).take(10)
+end
+```
+
+This is possible because `IO#to_list` creates a lazy list whereby each line is
+only ever read and processed as needed, in effect converting it to the first
+example.
+
+See the API documentation for details on all [`List`][LIST-DOC] methods.
+
+
+<h2>Deque <span style="font-size:0.7em">(<a href="http://rubydoc.info/github/hamstergem/hamster/master/Hamster/Deque">API Documentation</a>)</span></h2>
+
+A `Deque` (or "double-ended queue") is an ordered collection, which allows you to push and pop items from both front and back. This makes it perfect as an immutable stack *or* queue. Examples:
+
+``` ruby
+deque = Hamster::Deque[1, 2, 3] # => Hamster::Deque[1, 2, 3]
+deque.first                     # 1
+deque.last                      # 3
+deque.pop                       # => Hamster::Deque[1, 2]
+deque.push(:a)                  # => Hamster::Deque[1, 2, 3, :a]
+deque.shift                     # => Hamster::Deque[2, 3]
+deque.unshift(:a)               # => Hamster::Deque[:a, 1, 2, 3]
+```
+
+Of course, you can do the same thing with a `Vector`, but a `Deque` is more efficient. See the API documentation for details on all [`Deque`][DEQUE-DOC] methods.
+
+
+<h2>Transformations</h2>
+
+Hamster arrays, hashes, and nested structures of arrays and hashes may be transformed with the `update_in` method.
+
+``` ruby
+c = Hamster.from({
+  people: [{name: 'Chris', city: 'Lagos'}, {name: 'Pat', city: 'Madrid'}],
+  places: [{name: 'Lagos', population: 1}, {name: 'Madrid', population: 1}]})
+c2 = c.update_in(:people, 1, :city) { |old_city| 'Lagos' }
+c3 = c2.update_in(:places, 1, :population) { |old_population| old_population - 1 }
+c4 = c3.update_in(:places, 0, :population) { |old_population| old_population + 1 }
+Hamster.to_ruby(c4)
+# => {:places=>[{:population=>2, :name=>"Lagos"}, {:population=>0, :name=>"Madrid"}], :people=>[{:name=>"Chris", :city=>"Lagos"}, {:name=>"Pat", :city=>"Lagos"}]}
+```
+
+Naturally, `update_in` never mutates your collections.
+
+See `Hamster::Hash#update_in`, `Hamster::Vector#update_in`, and `Hamster::Associable#update_in` for details.

+Hamster
+=======
+
+Efficient, immutable, and thread-safe collection classes for Ruby.
+
+Hamster provides 6 [Persistent Data
+Structures][PDS]: {Hamster::Hash Hash}, {Hamster::Vector Vector}, {Hamster::Set Set}, {Hamster::SortedSet SortedSet}, {Hamster::List List}, and {Hamster::Deque Deque} (which works as an immutable queue or stack).
+
+Hamster collections are **immutable**. Whenever you modify a Hamster
+collection, the original is preserved and a modified copy is returned. This
+makes them inherently thread-safe and shareable. At the same time, they remain
+CPU and memory-efficient by sharing between copies.
+
+While Hamster collections are immutable, you can still mutate objects stored
+in them. We recommend that  you don't do this, unless you are sure you know
+what you are doing. Hamster collections are thread-safe and can be freely
+shared between threads, but you are responsible for making sure that the
+objects stored in them are used in a thread-safe manner.
+
+Hamster collections are almost always closed under a given operation. That is,
+whereas Ruby's collection methods always return arrays, Hamster collections
+will return an instance of the same class wherever possible.
+
+Where possible, Hamster collections offer an interface compatible with Ruby's
+built-in `Hash`, `Array`, and `Enumerable`, to ease code migration. Also, Hamster methods accept regular Ruby collections as arguments, so code which uses `Hamster` can easily interoperate with your other Ruby code.
+
+And lastly, Hamster lists are lazy, making it possible to (among other things)
+process "infinitely large" lists.
+
+[PDS]: http://en.wikipedia.org/wiki/Persistent_data_structure
+
+
+Using
+=====
+
+To make the collection classes available in your code:
+
+``` ruby
+require "hamster"
+```
+
+Or if you prefer to only pull in certain collection types:
+
+``` ruby
+require "hamster/hash"
+require "hamster/vector"
+require "hamster/set"
+require "hamster/sorted_set"
+require "hamster/list"
+require "hamster/deque"
+```
+
+<h2>Hash <span style="font-size:0.7em">({Hamster::Hash API Documentation}</a>)</span></h2>
+
+Constructing a Hamster `Hash` is almost as simple as a regular one:
+
+``` ruby
+person = Hamster::Hash[name: "Simon", gender: :male]
+# => Hamster::Hash[:name => "Simon", :gender => :male]
+```
+
+Accessing the contents will be familiar to you:
+
+``` ruby
+person[:name]                       # => "Simon"
+person.get(:gender)                 # => :male
+```
+
+Updating the contents is a little different than you are used to:
+
+``` ruby
+friend = person.put(:name, "James") # => Hamster::Hash[:name => "James", :gender => :male]
+person                              # => Hamster::Hash[:name => "Simon", :gender => :male]
+friend[:name]                       # => "James"
+person[:name]                       # => "Simon"
+```
+
+As you can see, updating the hash returned a copy leaving
+the original intact. Similarly, deleting a key returns
+yet another copy:
+
+``` ruby
+male = person.delete(:name)         # => Hamster::Hash[:gender => :male]
+person                              # => Hamster::Hash[:name => "Simon", :gender => :male]
+male.key?(:name)                    # => false
+person.key?(:name)                  # => true
+```
+
+Since it is immutable, Hamster's `Hash` doesn't provide an assignment
+(`Hash#[]=`) method. However, `Hash#put` can accept a block which
+transforms the value associated with a given key:
+
+``` ruby
+counters.put(:odds) { |value| value + 1 } # => Hamster::Hash[:odds => 1, :evens => 0]
+```
+
+Or more succinctly:
+
+``` ruby
+counters.put(:odds, &:next)         # => {:odds => 1, :evens => 0}
+```
+
+This is just the beginning; see the {Hamster::Hash API documentation} for details on all `Hash` methods.
+
+
+<h2>Vector <span style="font-size:0.7em">({Hamster::Vector API Documentation})</span></h2>
+
+A `Vector` is an integer-indexed collection much like an immutable `Array`. Examples:
+
+``` ruby
+vector = Hamster::Vector[1, 2, 3, 4] # => Hamster::Vector[1, 2, 3, 4]
+vector[0]                            # => 1
+vector[-1]                           # => 4
+vector.put(1, :a)                    # => Hamster::Vector[1, :a, 3, 4]
+vector.add(:b)                       # => Hamster::Vector[1, 2, 3, 4, :b]
+vector.insert(2, :a, :b)             # => Hamster::Vector[1, 2, :a, :b, 3, 4]
+vector.delete_at(0)                  # => Hamster::Vector[2, 3, 4]
+```
+
+Other `Array`-like methods like `#select`, `#map`, `#shuffle`, `#uniq`, `#reverse`,
+`#rotate`, `#flatten`, `#sort`, `#sort_by`, `#take`, `#drop`, `#take_while`,
+`#drop_while`, `#fill`, `#product`, and `#transpose` are also supported. See the
+{Hamster::Vector API documentation} for details on all `Vector` methods.
+
+
+<h2>Set <span style="font-size:0.7em">({Hamster::Set API Documentation})</span></h2>
+
+A `Set` is an unordered collection of values with no duplicates. It is much like the Ruby standard library's `Set`, but immutable. Examples:
+
+``` ruby
+set = Hamster::Set[:red, :blue, :yellow] # => Hamster::Set[:red, :blue, :yellow]
+set.include? :red                        # => true
+set.add :green                           # => Hamster::Set[:red, :blue, :yellow, :green]
+set.delete :blue                         # => Hamster::Set[:red, :yellow]
+set.superset? Hamster::Set[:red, :blue]  # => true
+set.union([:red, :blue, :pink])          # => Hamster::Set[:red, :blue, :yellow, :pink]
+set.intersection([:red, :blue, :pink])   # => Hamster::Set[:red, :blue]
+```
+
+Like most Hamster methods, the set-theoretic methods `#union`, `#intersection`, `#difference`, and `#exclusion` (aliased as `#|`, `#&`, `#-`, and `#^`) all work with regular Ruby collections, or indeed any `Enumerable` object. So just like all the other Hamster collections, `Hamster::Set` can easily be used in combination with "ordinary" Ruby code.
+
+See the {Hamster::Set API documentation} for details on all `Set` methods.
+
+
+<h2>SortedSet <span style="font-size:0.7em">({Hamster::SortedSet API Documentation})</span></h2>
+
+A `SortedSet` is like a `Set`, but ordered. You can do everything with it that you can
+do with a `Set`. Additionally, you can get the `#first` and `#last` item, or retrieve
+an item using an integral index:
+
+``` ruby
+set = Hamster::SortedSet['toast', 'jam', 'bacon'] # => Hamster::SortedSet["bacon", "jam", "toast"]
+set.first                                         # => "bacon"
+set.last                                          # => "toast"
+set[1]                                            # => "jam"
+```
+
+You can also specify the sort order using a block:
+
+``` ruby
+Hamster::SortedSet.new(['toast', 'jam', 'bacon']) { |a,b| b <=> a }
+Hamster::SortedSet.new(['toast', 'jam', 'bacon']) { |str| str.chars.last }
+```
+
+See the {Hamster::SortedSet API documentation} for details on all `SortedSet` methods.
+
+
+<h2>List <span style="font-size:0.7em">({Hamster::List API Documentation})</span></h2>
+
+Hamster `List`s have a *head* (the value at the front of the list),
+and a *tail* (a list of the remaining items):
+
+``` ruby
+list = Hamster::List[1, 2, 3]
+list.head                    # => 1
+list.tail                    # => Hamster::List[2, 3]
+```
+
+Add to a list with {Hamster::List#add}:
+
+``` ruby
+original = Hamster::List[1, 2, 3]
+copy = original.add(0)      # => Hamster::List[0, 1, 2, 3]
+```
+
+Notice how modifying a list actually returns a new list.
+That's because Hamster `List`s are immutable.
+
+### Laziness
+
+`List` is lazy where possible. It tries to defer processing items until
+absolutely necessary. For example, given a crude function to detect prime
+numbers:
+
+``` ruby
+def prime?(number)
+  2.upto(Math.sqrt(number).round) do |integer|
+    return false if (number % integer).zero?
+  end
+  true
+end
+```
+
+The following code will only call `#prime?` as many times as
+necessary to generate the first 3 prime numbers between 10,000
+and 1,000,000:
+
+``` ruby
+Hamster.interval(10_000, 1_000_000).select do |number|
+  prime?(number)
+end.take(3)
+  # => 0.0009s
+```
+
+Compare that to the conventional equivalent which needs to
+calculate all possible values in the range before taking the
+first three:
+
+``` ruby
+(10000..1000000).select do |number|
+  prime?(number)
+end.take(3)
+  # => 10s
+```
+
+### Construction
+
+Besides `Hamster::List[]` there are other ways to construct lists:
+
+  - {Hamster.interval Hamster.interval(from, to)} creates a lazy list
+    equivalent to a list containing all the values between
+    `from` and `to` without actually creating a list that big.
+
+  - {Hamster.stream Hamster.stream { ... }} allows you to creates infinite
+    lists. Each time a new value is required, the supplied
+    block is called. To generate a list of integers you
+    could do:
+
+    ``` ruby
+    count = 0
+    Hamster.stream { count += 1 }
+    ```
+
+  - {Hamster.repeat Hamster.repeat(x)} creates an infinite list with `x` the
+    value for every element.
+
+  - {Hamster.replicate Hamster.replicate(n, x)} creates a list of size `n` with
+    `x` the value for every element.
+
+  - {Hamster.iterate Hamster.iterate(x) { |x| ... }} creates an infinite
+    list where the first item is calculated by applying the
+    block on the initial argument, the second item by applying
+    the function on the previous result and so on. For
+    example, a simpler way to generate a list of integers
+    would be:
+
+    ``` ruby
+    Hamster.iterate(1) { |i| i + 1 }
+    ```
+
+    or even more succinctly:
+
+    ``` ruby
+    Hamster.iterate(1, &:next)
+    ```
+  - {Hamster::List.empty} returns an empty list, which you can
+    build up using repeated calls to {Hamster::List#add #add} or other `List` methods.
+
+### Core Extensions
+
+{Enumerable#to_list} will convert any existing `Enumerable` to a list, so you can
+slowly transition from built-in collection classes to Hamster.
+
+{IO#to_list} enables lazy processing of huge files. For example, imagine the
+following code to process a 100MB file:
+
+``` ruby
+require 'hamster/core_ext'
+
+File.open("my_100_mb_file.txt") do |file|
+  lines = []
+  file.each_line do |line|
+    break if lines.size == 10
+    lines << line.chomp.downcase.reverse
+  end
+end
+```
+
+Compare to the following more functional version:
+
+``` ruby
+File.open("my_100_mb_file.txt") do |file|
+  file.map(&:chomp).map(&:downcase).map(&:reverse).take(10)
+end
+```
+
+Unfortunately, though the second example reads nicely it
+takes many seconds to run (compared with milliseconds
+for the first) even though we're only interested in the first
+ten lines. Using `#to_list` we can get the running time back comparable to the
+imperative version.
+
+``` ruby
+File.open("my_100_mb_file.txt") do |file|
+  file.to_list.map(&:chomp).map(&:downcase).map(&:reverse).take(10)
+end
+```
+
+This is possible because `IO#to_list` creates a lazy list whereby each line is
+only ever read and processed as needed, in effect converting it to the first
+example.
+
+See the {Hamster::List API documentation} for details on all List methods.
+
+
+<h2>Deque <span style="font-size:0.7em">({Hamster::Deque API Documentation})</span></h2>
+
+A `Deque` (or "double-ended queue") is an ordered collection, which allows you to push and pop items from both front and back. This makes it perfect as an immutable stack *or* queue. Examples:
+
+``` ruby
+deque = Hamster::Deque[1, 2, 3] # => Hamster::Deque[1, 2, 3]
+deque.first                     # 1
+deque.last                      # 3
+deque.pop                       # => Hamster::Deque[1, 2]
+deque.push(:a)                  # => Hamster::Deque[1, 2, 3, :a]
+deque.shift                     # => Hamster::Deque[2, 3]
+deque.unshift(:a)               # => Hamster::Deque[:a, 1, 2, 3]
+```
+
+Of course, you can do the same thing with a `Vector`, but a `Deque` is more efficient. See the {Hamster::Deque API documentation} for details on all Deque methods.
+
+<h2>Transformations</h2>
+
+Hamster arrays, hashes, and nested structures of arrays and hashes may be transformed with the `update_in` method.
+
+``` ruby
+c = Hamster.from({
+  people: [{name: 'Chris', city: 'Lagos'}, {name: 'Pat', city: 'Madrid'}],
+  places: [{name: 'Lagos', population: 1}, {name: 'Madrid', population: 1}]})
+c2 = c.update_in(:people, 1, :city) { |old_city| 'Lagos' }
+c3 = c2.update_in(:places, 1, :population) { |old_population| old_population - 1 }
+c4 = c3.update_in(:places, 0, :population) { |old_population| old_population + 1 }
+Hamster.to_ruby(c4)
+# => {:places=>[{:population=>2, :name=>"Lagos"}, {:population=>0, :name=>"Madrid"}], :people=>[{:name=>"Chris", :city=>"Lagos"}, {:name=>"Pat", :city=>"Lagos"}]}
+```
+
+Naturally, `update_in` never mutates your collections.
+
+See {Hamster::Hash#update_in}, {Hamster::Vector#update_in}, and {Hamster::Associable#update_in} for details.

+  # To mix in `Associable`, your class must implement two methods:

+  # * `fetch(index, default = (missing_default = true))`
+  # * `put(index, item = yield(get(index)))`
+  # * `get(key)`

+    # of the given code block.  When traversing the nested containers
+    # non-existing keys are created with empty `Hash` values.

+    # The code block receives the existing value of the deeply nested key/index
+    # (or `nil` if it doesn't exist). This is useful for "transforming" the

+    #
+    # Naturally, the original container and sub-containers are left unmodified;

+
+  # A `Deque` (or double-ended queue) is an ordered, sequential collection of
+  # objects, which allows elements to be retrieved, added and removed at the
+  # front and end of the sequence in constant time. This makes `Deque` perfect
+  # for use as an immutable queue or stack.
+  #
+  # A `Deque` differs from a {Vector} in that vectors allow indexed access to
+  # any element in the collection. `Deque`s only allow access to the first and
+  # last element. But adding and removing from the ends of a `Deque` is faster
+  # than adding and removing from the ends of a {Vector}.
+  #
+  # To create a new `Deque`:
+  #
+  #     Hamster::Deque.new([:first, :second, :third])
+  #     Hamster::Deque[1, 2, 3, 4, 5]

+  # Or you can start with an empty deque and build it up:
+  #
+  #     Hamster::Deque.empty.push('b').push('c').unshift('a')
+  #
+  # Like all Hamster collections, `Deque` is immutable. The four basic
+  # operations that "modify" deques ({#push}, {#pop}, {#shift}, and
+  # {#unshift}) all return a new collection and leave the existing one
+  # unchanged.
+  #
+  # @example
+  #   deque = Hamster::Deque.empty                 # => Hamster::Deque[]
+  #   deque = deque.push('a').push('b').push('c')  # => Hamster::Deque['a', 'b', 'c']

+module Hamster
+  # A `Hamster::Hash` maps a set of unique keys to corresponding values, much
+  # like a dictionary maps from words to definitions. Given a key, it can store
+  # and retrieve an associated value in constant time. If an existing key is
+  # stored again, the new value will replace the old. It behaves much like
+  # Ruby's built-in Hash, which we will call RubyHash for clarity. Like
+  # RubyHash, two keys that are `#eql?` to each other and have the same
+  # `#hash` are considered identical in a `Hamster::Hash`.
+  #
+  # A `Hamster::Hash` can be created in a couple of ways:
+  #
+  #     Hamster::Hash.new(font_size: 10, font_family: 'Arial')
+  #     Hamster::Hash[first_name: 'John', last_name: 'Smith']
+  #
+  # Any `Enumerable` object which yields two-element `[key, value]` arrays
+  # can be used to initialize a `Hamster::Hash`:
+  #
+  #     Hamster::Hash.new([[:first_name, 'John'], [:last_name, 'Smith']])
+  #
+  # Key/value pairs can be added using {#put}. A new hash is returned and the
+  # existing one is left unchanged:
+  #
+  #     hash = Hamster::Hash[a: 100, b: 200]
+  #     hash.put(:c, 500) # => Hamster::Hash[:a => 100, :b => 200, :c => 500]
+  #     hash              # => Hamster::Hash[:a => 100, :b => 200]
+  #
+  # {#put} can also take a block, which is used to calculate the value to be
+  # stored.
+  #
+  #     hash.put(:a) { |current| current + 200 } # => Hamster::Hash[:a => 300, :b => 200]
+  #
+  # Since it is immutable, all methods which you might expect to "modify" a
+  # `Hamster::Hash` actually return a new hash and leave the existing one
+  # unchanged. This means that the `hash[key] = value` syntax from RubyHash
+  # *cannot* be used with `Hamster::Hash`.
+  #
+  # Nested data structures can easily be updated using {#update_in}:
+  #
+  #     hash = Hamster::Hash["a" => Hamster::Vector[Hamster::Hash["c" => 42]]]
+  #     hash.update_in("a", 0, "c") { |value| value + 5 }
+  #     # => Hamster::Hash["a" => Hamster::Hash["b" => Hamster::Hash["c" => 47]]]
+  #
+  # While a `Hamster::Hash` can iterate over its keys or values, it does not
+  # guarantee any specific iteration order (unlike RubyHash). Methods like
+  # {#flatten} do not guarantee the order of returned key/value pairs.
+  #
+  # Like RubyHash, a `Hamster::Hash` can have a default block which is used
+  # when looking up a key that does not exist. Unlike RubyHash, the default
+  # block will only be passed the missing key, without the hash itself:
+  #
+  #     hash = Hamster::Hash.new { |missing_key| missing_key * 10 }
+  #     hash[5] # => 50

+
+  # `Hamster::Set` is a collection of unordered values with no duplicates. Testing whether
+  # an object is present in the `Set` can be done in constant time. `Set` is also `Enumerable`, so you can
+  # iterate over the members of the set with {#each}, transform them with {#map}, filter
+  # them with {#select}, and so on. Some of the `Enumerable` methods are overridden to
+  # return Hamster collections.
+  #
+  # Like the `Set` class in Ruby's standard library, which we will call RubySet,
+  # `Hamster::Set` defines equivalency of objects using `#hash` and `#eql?`. No two
+  # objects with the same `#hash` code, and which are also `#eql?`, can coexist in the
+  # same `Set`. If one is already in the `Set`, attempts to add another one will have
+  # no effect.
+  #
+  # `Set`s have no natural ordering and cannot be compared using `#<=>`. However, they
+  # define {#<}, {#>}, {#<=}, and {#>=} as shorthand for {#proper_subset?},
+  # {#proper_superset?}, {#subset?}, and {#superset?} respectively.
+  #
+  # The basic set-theoretic operations {#union}, {#intersection}, {#difference}, and
+  # {#exclusion} work with any `Enumerable` object.
+  #
+  # A `Set` can be created in either of the following ways:
+  #
+  #     Hamster::Set.new([1, 2, 3]) # any Enumerable can be used to initialize
+  #     Hamster::Set['A', 'B', 'C', 'D']
+  #
+  # The latter 2 forms of initialization can be used with your own, custom subclasses
+  # of `Hamster::Set`.
+  #
+  # Unlike RubySet, all methods which you might expect to "modify" a `Hamster::Set`
+  # actually return a new set and leave the existing one unchanged.
+  #
+  # @example
+  #   set1 = Hamster::Set[1, 2] # => Hamster::Set[1, 2]
+  #   set2 = Hamster::Set[1, 2] # => Hamster::Set[1, 2]
+  #   set1 == set2              # => true
+  #   set3 = set1.add("foo")    # => Hamster::Set[1, 2, "foo"]
+  #   set3 - set2               # => Hamster::Set["foo"]
+  #   set3.subset?(set1)        # => false
+  #   set1.subset?(set3)        # => true

+module Hamster
+
+  # A `SortedSet` is a collection of ordered values with no duplicates. Unlike a
+  # {Vector}, in which items can appear in any arbitrary order, a `SortedSet` always
+  # keeps items either in their natural order, or in an order defined by a comparator
+  # block which is provided at initialization time.
+  #
+  # `SortedSet` uses `#<=>` (or its comparator block) to determine which items are
+  # equivalent. If the comparator indicates that an existing item and a new item are
+  # equal, any attempt to insert the new item will have no effect.
+  #
+  # This means that *all* the items inserted into any one `SortedSet` must all be
+  # comparable. For example, you cannot put `String`s and `Integer`s in the same
+  # `SortedSet`. This is unlike {Set}, which can store items of any type, as long
+  # as they all support `#hash` and `#eql?`.
+  #
+  # A `SortedSet` can be created in either of the following ways:
+  #
+  #     Hamster::SortedSet.new([1, 2, 3]) # any Enumerable can be used to initialize
+  #     Hamster::SortedSet['A', 'B', 'C', 'D']
+  #
+  # Or if you want to use a custom ordering:
+  #
+  #     Hamster::SortedSet.new([1,2,3]) { |a, b| -a <=> -b }
+  #     Hamster::SortedSet.new([1, 2, 3]) { |num| -num }
+  #
+  # `SortedSet` can use a 2-parameter block which returns 0, 1, or -1
+  # as a comparator (like `Array#sort`), *or* use a 1-parameter block to derive sort
+  # keys (like `Array#sort_by`) which will be compared using `#<=>`.
+  #
+  # Like all Hamster collections, `SortedSet`s are immutable. Any operation which you
+  # might expect to "modify" a `SortedSet` will actually return a new collection and
+  # leave the existing one unchanged.
+  #
+  # `SortedSet` supports the same basic set-theoretic operations as {Set}, including
+  # {#union}, {#intersection}, {#difference}, and {#exclusion}, as well as {#subset?},
+  # {#superset?}, and so on. Unlike {Set}, it does not define comparison operators like
+  # `#>` or `#<` as aliases for the superset/subset predicates. Instead, these comparison
+  # operators do a item-by-item comparison between the `SortedSet` and another sequential
+  # collection. (See `Array#<=>` for details.)
+  #
+  # Additionally, since `SortedSet`s are ordered, they also support indexed retrieval
+  # of items using {#at} or {#[]}. Like {Vector},
+  # negative indices count back from the end of the `SortedSet`.
+  #
+  # Getting the {#max} or {#min} item from a `SortedSet`, as defined by its comparator,
+  # is a constant time operation.

+# Ruby I18n
+
+[![Build Status](https://api.travis-ci.org/svenfuchs/i18n.svg?branch=master)](https://travis-ci.org/svenfuchs/i18n)
+
+Ruby Internationalization and localization solution.
+
+Features:
+
+* translation and localization
+* interpolation of values to translations (Ruby 1.9 compatible syntax)
+* pluralization (CLDR compatible)
+* customizable transliteration to ASCII
+* flexible defaults
+* bulk lookup
+* lambdas as translation data
+* custom key/scope separator
+* custom exception handlers
+* extensible architecture with a swappable backend
+
+Pluggable features:
+
+* Cache
+* Pluralization: lambda pluralizers stored as translation data
+* Locale fallbacks, RFC4647 compliant (optionally: RFC4646 locale validation)
+* Gettext support
+* Translation metadata
+
+Alternative backends:
+
+* Chain
+* ActiveRecord (optionally: ActiveRecord::Missing and ActiveRecord::StoreProcs)
+* KeyValue (uses active_support/json and cannot store procs)
+
+For more information and lots of resources see: [http://ruby-i18n.org/wiki](http://ruby-i18n.org/wiki)
+
+## Installation
+
+gem install i18n
+
+#### Rails version warning
+
+On Rails < 2.3.6 the method I18n.localize will fail with MissingInterpolationArgument (issue [20](http://github.com/svenfuchs/i18n/issues/issue/20). Upgrade to Rails 2.3.6 or higher (2.3.8 preferably) is recommended.
+
+### Installation on Rails < 2.3.5 (deprecated)
+
+Up to version 2.3.4 Rails will not accept i18n gems > 0.1.3. There is an unpacked
+gem inside of active_support/lib/vendor which gets loaded unless `gem 'i18n', '~> 0.1.3'`.
+This requirement is relaxed in [6da03653](http://github.com/rails/rails/commit/6da03653)
+
+The new i18n gem can be loaded from vendor/plugins like this:
+
+```
+def reload_i18n!
+  raise "Move to i18n version 0.2.0 or greater" if Rails.version > "2.3.4"
+
+  $:.grep(/i18n/).each { |path| $:.delete(path) }
+  I18n::Backend.send :remove_const, "Simple"
+  $: << Rails.root.join('vendor', 'plugins', 'i18n', 'lib').to_s
+end
+```
+
+Then you can `reload_i18n!` inside an i18n initializer.
+
+## Tests
+
+You can run tests both with
+
+* `rake test` or just `rake`
+* run any test file directly, e.g. `ruby -Ilib -Itest test/api/simple_test.rb`
+* run all tests with `ruby -Ilib -Itest test/all.rb`
+
+You can run all tests against all Gemfiles with
+
+* `ruby test/run_all.rb`
+
+The structure of the test suite is a bit unusual as it uses modules to reuse
+particular tests in different test cases.
+
+The reason for this is that we need to enforce the I18n API across various
+combinations of extensions. E.g. the Simple backend alone needs to support
+the same API as any combination of feature and/or optimization modules included
+to the Simple backend. We test this by reusing the same API defition (implemented
+as test methods) in test cases with different setups.
+
+You can find the test cases that enforce the API in test/api. And you can find
+the API definition test methods in test/api/tests.
+
+All other test cases (e.g. as defined in test/backend, test/core_ext) etc.
+follow the usual test setup and should be easy to grok.

+    #
+    # *LOOKUP*
+    #
+    # Translation data is organized as a nested hash using the upper-level keys
+    # as namespaces. <em>E.g.</em>, ActionView ships with the translation:
+    # <tt>:date => {:formats => {:short => "%b %d"}}</tt>.
+    #
+    # Translations can be looked up at any level of this hash using the key argument
+    # and the scope option. <em>E.g.</em>, in this example <tt>I18n.t :date</tt>
+    # returns the whole translations hash <tt>{:formats => {:short => "%b %d"}}</tt>.
+    #
+    # Key can be either a single key or a dot-separated key (both Strings and Symbols
+    # work). <em>E.g.</em>, the short format can be looked up using both:
+    #   I18n.t 'date.formats.short'
+    #   I18n.t :'date.formats.short'
+    #
+    # Scope can be either a single key, a dot-separated key or an array of keys
+    # or dot-separated keys. Keys and scopes can be combined freely. So these
+    # examples will all look up the same short date format:
+    #   I18n.t 'date.formats.short'
+    #   I18n.t 'formats.short', :scope => 'date'
+    #   I18n.t 'short', :scope => 'date.formats'
+    #   I18n.t 'short', :scope => %w(date formats)
+    #
+    # *INTERPOLATION*
+    #
+    # Translations can contain interpolation variables which will be replaced by
+    # values passed to #translate as part of the options hash, with the keys matching
+    # the interpolation variable names.
+    #
+    # <em>E.g.</em>, with a translation <tt>:foo => "foo %{bar}"</tt> the option
+    # value for the key +bar+ will be interpolated into the translation:
+    #   I18n.t :foo, :bar => 'baz' # => 'foo baz'
+    #
+    # *PLURALIZATION*
+    #
+    # Translation data can contain pluralized translations. Pluralized translations
+    # are arrays of singluar/plural versions of translations like <tt>['Foo', 'Foos']</tt>.
+    #
+    # Note that <tt>I18n::Backend::Simple</tt> only supports an algorithm for English
+    # pluralization rules. Other algorithms can be supported by custom backends.
+    #
+    # This returns the singular version of a pluralized translation:
+    #   I18n.t :foo, :count => 1 # => 'Foo'
+    #
+    # These both return the plural version of a pluralized translation:
+    #   I18n.t :foo, :count => 0 # => 'Foos'
+    #   I18n.t :foo, :count => 2 # => 'Foos'
+    #
+    # The <tt>:count</tt> option can be used both for pluralization and interpolation.
+    # <em>E.g.</em>, with the translation
+    # <tt>:foo => ['%{count} foo', '%{count} foos']</tt>, count will
+    # be interpolated to the pluralized translation:
+    #   I18n.t :foo, :count => 1 # => '1 foo'
+    #
+    # *DEFAULTS*
+    #
+    # This returns the translation for <tt>:foo</tt> or <tt>default</tt> if no translation was found:
+    #   I18n.t :foo, :default => 'default'
+    #
+    # This returns the translation for <tt>:foo</tt> or the translation for <tt>:bar</tt> if no
+    # translation for <tt>:foo</tt> was found:
+    #   I18n.t :foo, :default => :bar
+    #
+    # Returns the translation for <tt>:foo</tt> or the translation for <tt>:bar</tt>
+    # or <tt>default</tt> if no translations for <tt>:foo</tt> and <tt>:bar</tt> were found.
+    #   I18n.t :foo, :default => [:bar, 'default']
+    #
+    # *BULK LOOKUP*
+    #
+    # This returns an array with the translations for <tt>:foo</tt> and <tt>:bar</tt>.
+    #   I18n.t [:foo, :bar]
+    #
+    # Can be used with dot-separated nested keys:
+    #   I18n.t [:'baz.foo', :'baz.bar']
+    #
+    # Which is the same as using a scope option:
+    #   I18n.t [:foo, :bar], :scope => :baz
+    #
+    # *LAMBDAS*
+    #
+    # Both translations and defaults can be given as Ruby lambdas. Lambdas will be
+    # called and passed the key and options.
+    #
+    # E.g. assuming the key <tt>:salutation</tt> resolves to:
+    #   lambda { |key, options| options[:gender] == 'm' ? "Mr. %{options[:name]}" : "Mrs. %{options[:name]}" }
+    #
+    # Then <tt>I18n.t(:salutation, :gender => 'w', :name => 'Smith') will result in "Mrs. Smith".
+    #
+    # It is recommended to use/implement lambdas in an "idempotent" way. E.g. when
+    # a cache layer is put in front of I18n.translate it will generate a cache key
+    # from the argument values passed to #translate. Therefor your lambdas should
+    # always return the same translations/values per unique combination of argument
+    # values.

+    #    # => "???"

+    # It's also possible to add support for per-locale transliterations. I18n
+    # expects transliteration rules to be stored at
+    # <tt>i18n.transliterate.rule</tt>.
+    #
+    # Transliteration rules can either be a Hash or a Proc. Procs must accept a
+    # single string argument. Hash rules inherit the default transliteration
+    # rules, while Procs do not.
+    #
+    # *Examples*
+    #
+    # Setting a Hash in <locale>.yml:
+    #
+    #    i18n:
+    #      transliterate:
+    #        rule:
+    #          ü: "ue"
+    #          ö: "oe"
+    #
+    # Setting a Hash using Ruby:
+    #
+    #     store_translations(:de, :i18n => {
+    #       :transliterate => {
+    #         :rule => {

+    #           "ö" => "oe"
+    #         }
+    #       }
+    #     )
+    #
+    # Setting a Proc:

+    #     translit = lambda {|string| MyTransliterator.transliterate(string) }
+    #     store_translations(:xx, :i18n => {:transliterate => {:rule => translit})

+# The Cascade module adds the ability to do cascading lookups to backends that

+#
+# By cascading lookups we mean that for any key that can not be found the
+# Cascade module strips one segment off the scope part of the key and then
+# tries to look up the key in that scope.
+#
+# E.g. when a lookup for the key :"foo.bar.baz" does not yield a result then
+# the segment :bar will be stripped off the scope part :"foo.bar" and the new
+# scope :foo will be used to look up the key :baz. If that does not succeed
+# then the remaining scope segment :foo will be omitted, too, and again the
+# key :baz will be looked up (now with no scope).
+#
+# To enable a cascading lookup one passes the :cascade option:
+#
+#   I18n.t(:'foo.bar.baz', :cascade => true)
+#
+# This will return the first translation found for :"foo.bar.baz", :"foo.baz"
+# or :baz in this order.
+#
+# The cascading lookup takes precedence over resolving any given defaults.
+# I.e. defaults will kick in after the cascading lookups haven't succeeded.

+module I18n
+  module Backend
+    # This is a basic backend for key value stores. It receives on
+    # initialization the store, which should respond to three methods:
+    #
+    # * store#[](key)         - Used to get a value
+    # * store#[]=(key, value) - Used to set a value
+    # * store#keys            - Used to get all keys
+    #
+    # Since these stores only supports string, all values are converted
+    # to JSON before being stored, allowing it to also store booleans,
+    # hashes and arrays. However, this store does not support Procs.
+    #
+    # As the ActiveRecord backend, Symbols are just supported when loading
+    # translations from the filesystem or through explicit store translations.
+    #
+    # Also, avoid calling I18n.available_locales since it's a somehow
+    # expensive operation in most stores.
+    #
+    # == Example
+    #
+    # To setup I18n to use TokyoCabinet in memory is quite straightforward:
+    #
+    #   require 'rufus/tokyo/cabinet' # gem install rufus-tokyo
+    #   I18n.backend = I18n::Backend::KeyValue.new(Rufus::Tokyo::Cabinet.new('*'))
+    #
+    # == Performance
+    #
+    # You may make this backend even faster by including the Memoize module.
+    # However, notice that you should properly clear the cache if you change
+    # values directly in the key-store.
+    #
+    # == Subtrees
+    #
+    # In most backends, you are allowed to retrieve part of a translation tree:
+    #
+    #   I18n.backend.store_translations :en, :foo => { :bar => :baz }
+    #   I18n.t "foo" #=> { :bar => :baz }
+    #
+    # This backend supports this feature by default, but it slows down the storage
+    # of new data considerably and makes hard to delete entries. That said, you are
+    # allowed to disable the storage of subtrees on initialization:
+    #
+    #   I18n::Backend::KeyValue.new(@store, false)
+    #
+    # This is useful if you are using a KeyValue backend chained to a Simple backend.

+    # There are three ways to use it:

+    # * Using a single argument or Array of arguments.
+    #
+    #   This is the default behaviour of the String class. See Kernel#sprintf for

+    #   Example:
+    #
+    #     "%d %s" % [1, "message"]

+    #
+    # * Using a Hash as an argument and unformatted, named placeholders.
+    #
+    #   When you pass a Hash as an argument and specify placeholders with %{foo}
+    #   it will interpret the hash values as named arguments.
+    #
+    #   Example:
+    #
+    #     "%{firstname}, %{lastname}" % {:firstname => "Masao", :lastname => "Mutoh"}
+    #     # => "Masao Mutoh"
+    #
+    # * Using a Hash as an argument and formatted, named placeholders.
+    #
+    #   When you pass a Hash as an argument and specify placeholders with %<foo>d
+    #   it will interpret the hash values as named arguments and format the value
+    #   according to the formatting instruction appended to the closing >.
+    #
+    #   Example:
+    #
+    #     "%<integer>d, %<float>.1f" % { :integer => 10, :float => 43.4 }

+# Locale Fallbacks
+#
+# Extends the I18n module to hold a fallbacks instance which is set to an
+# instance of I18n::Locale::Fallbacks by default but can be swapped with a
+# different implementation.
+#
+# Locale fallbacks will compute a number of fallback locales for a given locale.
+# For example:
+#
+# <pre><code>
+# I18n.fallbacks[:"es-MX"] # => [:"es-MX", :es, :en] </code></pre>
+#
+# Locale fallbacks always fall back to
+#
+#   * all parent locales of a given locale (e.g. :es for :"es-MX") first,
+#   * the current default locales and all of their parents second
+#
+# The default locales are set to [I18n.default_locale] by default but can be
+# set to something else.
+#
+# One can additionally add any number of additional fallback locales manually.
+# These will be added before the default locales to the fallback chain. For
+# example:
+#
+#   # using the default locale as default fallback locale
+#
+#   I18n.default_locale = :"en-US"
+#   I18n.fallbacks = I18n::Locale::Fallbacks.new(:"de-AT" => :"de-DE")
+#   I18n.fallbacks[:"de-AT"] # => [:"de-AT", :"de-DE", :de, :"en-US", :en]
+#
+#   # using a custom locale as default fallback locale
+#
+#   I18n.fallbacks = I18n::Locale::Fallbacks.new(:"en-GB", :"de-AT" => :de, :"de-CH" => :de)
+#   I18n.fallbacks[:"de-AT"] # => [:"de-AT", :de, :"en-GB", :en]
+#   I18n.fallbacks[:"de-CH"] # => [:"de-CH", :de, :"en-GB", :en]

+#   # mapping fallbacks to an existing instance
+#
+#   # people speaking Catalan also speak Spanish as spoken in Spain
+#   fallbacks = I18n.fallbacks

+#
+#   # people speaking Arabian as spoken in Palestine also speak Hebrew as spoken in Israel
+#   fallbacks.map(:"ar-PS" => :"he-IL")
+#   fallbacks[:"ar-PS"] # => [:"ar-PS", :ar, :"he-IL", :he, :"en-US", :en]

+
+Interception (intercept + exception) allows you to intercept all exceptions as they are
+raised.
+
+Installation
+============
+
+As with all rubygems, use gem to install:
+
+```shell
+gem install interception
+```
+
+Or, if you're using bundler:
+
+```ruby
+source 'https://rubygems.org'
+gem 'interception'
+```
+
+Usage
+=====
+
+Add and remove listeners. They'll be called whenever an exception is raised (whether or
+not it would later be rescued) with both the exception object, and the binding from which
+it was raised. The binding can be used to discover further information about the context.
+
+```ruby
+require 'interception'
+listener = lambda{ |exception, binding|
+  puts "raised: #{exception.inspect}"
+}
+
+Interception.listen(listener)
+
+begin
+  raise "oopsy"
+rescue => exception
+  puts "rescued: #{exception.inspect}"
+end
+
+raise "daisy"
+
+Interception.unlisten(listener)
+```
+
+In the common case that you want to listen to events for the duration of a block, you can
+also pass that block to listen:
+
+```ruby
+require 'interception'
+def log_exceptions(&block)
+  Interception.listen(block) do |exception, binding|
+    puts "raised: #{exception.inspect} from #{binding.eval("__method__")}"
+  end
+end
+
+def hello
+  raise "oopsy"
+rescue => exception
+  puts "rescued: #{exception.inspect} in #{__method__}"
+  raise "daisy"
+end
+
+log_exceptions do
+  hello
+end
+```
+
+Your listen block is run as through it were called by `Kernel#raise`, so try not to raise
+an exception from within it, or you will loose the original exception.
+
+Known bugs
+==========
+
+* On rubinius we don't catch some low-level exceptions (like `ZeroDivisionError`).
+* On MRI-1.8.7, the binding sometimes has the wrong value for `self`.
+* The Interception versions prior to `0.4` **do not** support MRI-2.1.0. `>= 0.4` does support it.

+# kramdown
+
+## Readme first!
+
+kramdown was originally licensed under the GPL until the 1.0.0 release. However, due to the many
+requests it is now released under the MIT license and therefore can easily be used in commercial
+projects, too.
+
+However, if you use kramdown in a commercial setting, please consider **contributing back any
+changes** for the benefit of the community and/or **making a donation** (see the links in the
+sidebar on the [kramdown homepage](http://kramdown.gettalong.org/)!
+
+
+## Introduction
+
+kramdown is yet-another-markdown-parser but fast, pure Ruby, using a strict syntax definition and
+supporting several common extensions.
+
+The syntax definition for the kramdown syntax can be found in **doc/syntax.page** (or online at
+<http://kramdown.gettalong.org/syntax.html>) and a quick reference is available in
+**doc/quickref.page** or online at <http://kramdown.gettalong.org/quickref.html>.
+
+The kramdown library is mainly written to support the kramdown-to-HTML conversion chain. However,
+due to its flexibility it supports other input and output formats as well. Here is a list of the
+supported formats:
+
+* input formats: kramdown (a Markdown superset), Markdown, HTML
+* output formats: HTML, kramdown, LaTeX (and therefore PDF)
+
+All the documentation on the available input and output formats is available in the **doc/**
+directory and online at <http://kramdown.gettalong.org>.
+
+Starting from version 1.0.0 kramdown is using a versioning scheme with major, minor and patch parts
+in the version number where the major number changes on backwards-incompatible changes, the minor
+number on the introduction of new features and the patch number on everything else.
+
+
+## Usage
+
+kramdown has a basic *Cloth API, so using kramdown is as easy as
+
+```ruby
+require 'kramdown'
+
+Kramdown::Document.new(text).to_html
+```
+
+For detailed information have a look at the API documentation of the `Kramdown::Document` class.
+
+The full API documentation is available at <http://kramdown.gettalong.org/rdoc/>, other sites with an
+API documentation for kramdown probably don't provide the complete documentation!
+
+There are also some third-party libraries that extend the functionality of kramdown -- see the
+kramdown Wiki at <https://github.com/gettalong/kramdown/wiki>.
+
+
+## Development
+
+Just clone the git repository as described in **doc/installation.page** and you are good to go. You
+probably want to install `rake` so that you can use the provided rake tasks. Aside from that:
+
+* The `tidy` binary needs to be installed for the automatically derived tests to work.
+* The `latex` binary needs to be installed for the latex-compilation tests to work.
+
+
+## License
+
+MIT - see the **COPYING** file.

+
+Getting the Gist of Markdown's Formatting Syntax
+------------------------------------------------
+
+This page offers a brief overview of what it's like to use Markdown.
+The [syntax page] [s] provides complete, detailed documentation for
+every feature, but Markdown should be very easy to pick up simply by
+looking at a few examples of it in action. The examples on this page
+are written in a before/after style, showing example syntax and the
+HTML output produced by Markdown.
+
+It's also helpful to simply try Markdown out; the [Dingus] [d] is a
+web application that allows you type your own Markdown-formatted text
+and translate it to XHTML.
+
+**Note:** This document is itself written using Markdown; you
+can [see the source for it by adding '.text' to the URL] [src].
+
+  [s]: /projects/markdown/syntax  "Markdown Syntax"
+  [d]: /projects/markdown/dingus  "Markdown Dingus"

+
+
+## Paragraphs, Headers, Blockquotes ##
+
+A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing spaces or tabs is considered
+blank.) Normal paragraphs should not be intended with spaces or tabs.
+
+Markdown offers two styles of headers: *Setext* and *atx*.
+Setext-style headers for `<h1>` and `<h2>` are created by
+"underlining" with equal signs (`=`) and hyphens (`-`), respectively.
+To create an atx-style header, you put 1-6 hash marks (`#`) at the
+beginning of the line -- the number of hashes equals the resulting
+HTML header level.
+
+Blockquotes are indicated using email-style '`>`' angle brackets.
+
+Markdown:
+
+    A First Level Header
+    ====================
+    
+    A Second Level Header
+    ---------------------
+
+    Now is the time for all good men to come to
+    the aid of their country. This is just a
+    regular paragraph.
+
+    The quick brown fox jumped over the lazy
+    dog's back.
+    
+    ### Header 3
+
+    > This is a blockquote.
+    > 
+    > This is the second paragraph in the blockquote.
+    >
+    > ## This is an H2 in a blockquote
+
+
+Output:
+
+    <h1>A First Level Header</h1>
+    
+    <h2>A Second Level Header</h2>
+    
+    <p>Now is the time for all good men to come to
+    the aid of their country. This is just a
+    regular paragraph.</p>
+    
+    <p>The quick brown fox jumped over the lazy
+    dog's back.</p>
+    
+    <h3>Header 3</h3>
+    
+    <blockquote>
+        <p>This is a blockquote.</p>
+        
+        <p>This is the second paragraph in the blockquote.</p>
+        
+        <h2>This is an H2 in a blockquote</h2>
+    </blockquote>
+
+
+
+### Phrase Emphasis ###
+
+Markdown uses asterisks and underscores to indicate spans of emphasis.
+
+Markdown:
+
+    Some of these words *are emphasized*.
+    Some of these words _are emphasized also_.
+    
+    Use two asterisks for **strong emphasis**.
+    Or, if you prefer, __use two underscores instead__.
+
+Output:
+
+    <p>Some of these words <em>are emphasized</em>.
+    Some of these words <em>are emphasized also</em>.</p>
+    
+    <p>Use two asterisks for <strong>strong emphasis</strong>.
+    Or, if you prefer, <strong>use two underscores instead</strong>.</p>
+   
+
+
+## Lists ##
+
+Unordered (bulleted) lists use asterisks, pluses, and hyphens (`*`,
+`+`, and `-`) as list markers. These three markers are
+interchangable; this:
+
+    *   Candy.
+    *   Gum.
+    *   Booze.
+
+this:
+
+    +   Candy.
+    +   Gum.
+    +   Booze.
+
+and this:
+
+    -   Candy.
+    -   Gum.
+    -   Booze.
+
+all produce the same output:
+
+    <ul>
+    <li>Candy.</li>
+    <li>Gum.</li>
+    <li>Booze.</li>
+    </ul>
+
+Ordered (numbered) lists use regular numbers, followed by periods, as
+list markers:
+
+    1.  Red
+    2.  Green
+    3.  Blue
+
+Output:
+
+    <ol>
+    <li>Red</li>
+    <li>Green</li>
+    <li>Blue</li>
+    </ol>
+
+If you put blank lines between items, you'll get `<p>` tags for the
+list item text. You can create multi-paragraph list items by indenting
+the paragraphs by 4 spaces or 1 tab:
+
+    *   A list item.
+    
+        With multiple paragraphs.
+
+    *   Another item in the list.
+
+Output:
+
+    <ul>
+    <li><p>A list item.</p>
+    <p>With multiple paragraphs.</p></li>
+    <li><p>Another item in the list.</p></li>
+    </ul>
+    
+
+
+### Links ###
+
+Markdown supports two styles for creating links: *inline* and
+*reference*. With both styles, you use square brackets to delimit the
+text you want to turn into a link.
+
+Inline-style links use parentheses immediately after the link text.
+For example:
+
+    This is an [example link](http://example.com/).
+
+Output:
+
+    <p>This is an <a href="http://example.com/">
+    example link</a>.</p>
+
+Optionally, you may include a title attribute in the parentheses:
+
+    This is an [example link](http://example.com/ "With a Title").
+
+Output:
+
+    <p>This is an <a href="http://example.com/" title="With a Title">
+    example link</a>.</p>
+
+Reference-style links allow you to refer to your links by names, which
+you define elsewhere in your document:
+
+    I get 10 times more traffic from [Google][1] than from
+    [Yahoo][2] or [MSN][3].
+
+    [1]: http://google.com/        "Google"
+    [2]: http://search.yahoo.com/  "Yahoo Search"
+    [3]: http://search.msn.com/    "MSN Search"
+
+Output:
+
+    <p>I get 10 times more traffic from <a href="http://google.com/"
+    title="Google">Google</a> than from <a href="http://search.yahoo.com/"
+    title="Yahoo Search">Yahoo</a> or <a href="http://search.msn.com/"
+    title="MSN Search">MSN</a>.</p>
+
+The title attribute is optional. Link names may contain letters,
+numbers and spaces, but are *not* case sensitive:
+
+    I start my morning with a cup of coffee and
+    [The New York Times][NY Times].
+
+    [ny times]: http://www.nytimes.com/
+
+Output:
+
+    <p>I start my morning with a cup of coffee and
+    <a href="http://www.nytimes.com/">The New York Times</a>.</p>
+
+
+### Images ###
+
+Image syntax is very much like link syntax.
+
+Inline (titles are optional):
+
+    ![alt text](/path/to/img.jpg "Title")
+
+Reference-style:
+
+    ![alt text][id]
+
+    [id]: /path/to/img.jpg "Title"
+
+Both of the above examples produce the same output:
+
+    <img src="/path/to/img.jpg" alt="alt text" title="Title" />
+
+
+
+### Code ###
+
+In a regular paragraph, you can create code span by wrapping text in
+backtick quotes. Any ampersands (`&`) and angle brackets (`<` or
+`>`) will automatically be translated into HTML entities. This makes
+it easy to use Markdown to write about HTML example code:
+
+    I strongly recommend against using any `<blink>` tags.
+
+    I wish SmartyPants used named entities like `—`
+    instead of decimal-encoded entites like `—`.
+
+Output:
+
+    <p>I strongly recommend against using any
+    <code><blink></code> tags.</p>
+    
+    <p>I wish SmartyPants used named entities like
+    <code>&mdash;</code> instead of decimal-encoded
+    entites like <code>&#8212;</code>.</p>
+
+
+To specify an entire block of pre-formatted code, indent every line of
+the block by 4 spaces or 1 tab. Just like with code spans, `&`, `<`,
+and `>` characters will be escaped automatically.
+
+Markdown:
+
+    If you want your page to validate under XHTML 1.0 Strict,
+    you've got to put paragraph tags in your blockquotes:
+
+        <blockquote>
+            <p>For example.</p>
+        </blockquote>
+
+Output:

+    you've got to put paragraph tags in your blockquotes:</p>
+    
+    <pre><code><blockquote>

+
+<h2 id="overview">Overview</h2>
+
+<h3 id="philosophy">Philosophy</h3>
+
+Markdown is intended to be as easy-to-read and easy-to-write as is feasible.
+
+Readability, however, is emphasized above all else. A Markdown-formatted
+document should be publishable as-is, as plain text, without looking
+like it's been marked up with tags or formatting instructions. While
+Markdown's syntax has been influenced by several existing text-to-HTML
+filters -- including [Setext] [1], [atx] [2], [Textile] [3], [reStructuredText] [4],
+[Grutatext] [5], and [EtText] [6] -- the single biggest source of
+inspiration for Markdown's syntax is the format of plain text email.
+
+  [1]: http://docutils.sourceforge.net/mirror/setext.html
+  [2]: http://www.aaronsw.com/2002/atx/
+  [3]: http://textism.com/tools/textile/
+  [4]: http://docutils.sourceforge.net/rst.html
+  [5]: http://www.triptico.com/software/grutatxt.html
+  [6]: http://ettext.taint.org/doc/
+
+To this end, Markdown's syntax is comprised entirely of punctuation
+characters, which punctuation characters have been carefully chosen so
+as to look like what they mean. E.g., asterisks around a word actually
+look like \*emphasis\*. Markdown lists look like, well, lists. Even
+blockquotes look like quoted passages of text, assuming you've ever
+used email.
+
+
+
+<h3 id="html">Inline HTML</h3>
+
+Markdown's syntax is intended for one purpose: to be used as a
+format for *writing* for the web.
+
+Markdown is not a replacement for HTML, or even close to it. Its
+syntax is very small, corresponding only to a very small subset of
+HTML tags. The idea is *not* to create a syntax that makes it easier
+to insert HTML tags. In my opinion, HTML tags are already easy to
+insert. The idea for Markdown is to make it easy to read, write, and
+edit prose. HTML is a *publishing* format; Markdown is a *writing*
+format. Thus, Markdown's formatting syntax only addresses issues that
+can be conveyed in plain text.
+
+For any markup that is not covered by Markdown's syntax, you simply
+use HTML itself. There's no need to preface it or delimit it to
+indicate that you're switching from Markdown to HTML; you just use
+the tags.
+
+The only restrictions are that block-level HTML elements -- e.g. `<div>`,
+`<table>`, `<pre>`, `<p>`, etc. -- must be separated from surrounding
+content by blank lines, and the start and end tags of the block should
+not be indented with tabs or spaces. Markdown is smart enough not
+to add extra (unwanted) `<p>` tags around HTML block-level tags.
+
+For example, to add an HTML table to a Markdown article:
+
+    This is a regular paragraph.
+
+    <table>
+        <tr>
+            <td>Foo</td>
+        </tr>
+    </table>
+
+    This is another regular paragraph.
+
+Note that Markdown formatting syntax is not processed within block-level
+HTML tags. E.g., you can't use Markdown-style `*emphasis*` inside an
+HTML block.
+
+Span-level HTML tags -- e.g. `<span>`, `<cite>`, or `<del>` -- can be
+used anywhere in a Markdown paragraph, list item, or header. If you
+want, you can even use HTML tags instead of Markdown formatting; e.g. if
+you'd prefer to use HTML `<a>` or `<img>` tags instead of Markdown's
+link or image syntax, go right ahead.
+
+Unlike block-level HTML tags, Markdown syntax *is* processed within
+span-level tags.
+
+
+<h3 id="autoescape">Automatic Escaping for Special Characters</h3>
+
+In HTML, there are two characters that demand special treatment: `<`
+and `&`. Left angle brackets are used to start tags; ampersands are
+used to denote HTML entities. If you want to use them as literal
+characters, you must escape them as entities, e.g. `<`, and
+`&`.
+
+Ampersands in particular are bedeviling for web writers. If you want to
+write about 'AT&T', you need to write '`AT&T`'. You even need to
+escape ampersands within URLs. Thus, if you want to link to:
+
+    http://images.google.com/images?num=30&q=larry+bird
+
+you need to encode the URL as:
+
+    http://images.google.com/images?num=30&q=larry+bird
+
+in your anchor tag `href` attribute. Needless to say, this is easy to
+forget, and is probably the single most common source of HTML validation
+errors in otherwise well-marked-up web sites.
+
+Markdown allows you to use these characters naturally, taking care of
+all the necessary escaping for you. If you use an ampersand as part of
+an HTML entity, it remains unchanged; otherwise it will be translated
+into `&`.
+
+So, if you want to include a copyright symbol in your article, you can write:
+
+    ©
+
+and Markdown will leave it alone. But if you write:
+
+    AT&T
+
+Markdown will translate it to:
+
+    AT&T
+
+Similarly, because Markdown supports [inline HTML](#html), if you use
+angle brackets as delimiters for HTML tags, Markdown will treat them as
+such. But if you write:
+
+    4 < 5
+
+Markdown will translate it to:
+
+    4 < 5
+
+However, inside Markdown code spans and blocks, angle brackets and
+ampersands are *always* encoded automatically. This makes it easy to use
+Markdown to write about HTML code. (As opposed to raw HTML, which is a
+terrible format for writing about HTML syntax, because every single `<`
+and `&` in your example code needs to be escaped.)
+
+
+* * *
+
+
+<h2 id="block">Block Elements</h2>
+
+
+<h3 id="p">Paragraphs and Line Breaks</h3>
+
+A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing but spaces or tabs is considered
+blank.) Normal paragraphs should not be intended with spaces or tabs.
+
+The implication of the "one or more consecutive lines of text" rule is
+that Markdown supports "hard-wrapped" text paragraphs. This differs
+significantly from most other text-to-HTML formatters (including Movable
+Type's "Convert Line Breaks" option) which translate every line break
+character in a paragraph into a `<br />` tag.
+
+When you *do* want to insert a `<br />` break tag using Markdown, you
+end a line with two or more spaces, then type return.
+
+Yes, this takes a tad more effort to create a `<br />`, but a simplistic
+"every line break is a `<br />`" rule wouldn't work for Markdown.
+Markdown's email-style [blockquoting][bq] and multi-paragraph [list items][l]
+work best -- and look better -- when you format them with hard breaks.
+
+  [bq]: #blockquote
+  [l]:  #list
+
+
+
+<h3 id="header">Headers</h3>
+
+Markdown supports two styles of headers, [Setext] [1] and [atx] [2].
+
+Setext-style headers are "underlined" using equal signs (for first-level
+headers) and dashes (for second-level headers). For example:
+
+    This is an H1
+    =============
+
+    This is an H2
+    -------------
+
+Any number of underlining `=`'s or `-`'s will work.
+
+Atx-style headers use 1-6 hash characters at the start of the line,
+corresponding to header levels 1-6. For example:
+
+    # This is an H1
+
+    ## This is an H2
+
+    ###### This is an H6
+
+Optionally, you may "close" atx-style headers. This is purely
+cosmetic -- you can use this if you think it looks better. The
+closing hashes don't even need to match the number of hashes
+used to open the header. (The number of opening hashes
+determines the header level.) :
+
+    # This is an H1 #
+
+    ## This is an H2 ##
+
+    ### This is an H3 ######
+
+
+<h3 id="blockquote">Blockquotes</h3>
+
+Markdown uses email-style `>` characters for blockquoting. If you're
+familiar with quoting passages of text in an email message, then you
+know how to create a blockquote in Markdown. It looks best if you hard
+wrap the text and put a `>` before every line:
+
+    > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+    > consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+    > Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+    > 
+    > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+    > id sem consectetuer libero luctus adipiscing.
+
+Markdown allows you to be lazy and only put the `>` before the first
+line of a hard-wrapped paragraph:
+
+    > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+    consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+    Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+
+    > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+    id sem consectetuer libero luctus adipiscing.
+
+Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by
+adding additional levels of `>`:
+
+    > This is the first level of quoting.
+    >
+    > > This is nested blockquote.
+    >
+    > Back to the first level.
+
+Blockquotes can contain other Markdown elements, including headers, lists,
+and code blocks:
+
+	> ## This is a header.
+	> 
+	> 1.   This is the first list item.
+	> 2.   This is the second list item.
+	> 
+	> Here's some example code:
+	> 
+	>     return shell_exec("echo $input | $markdown_script");
+
+Any decent text editor should make email-style quoting easy. For
+example, with BBEdit, you can make a selection and choose Increase
+Quote Level from the Text menu.
+
+
+<h3 id="list">Lists</h3>
+
+Markdown supports ordered (numbered) and unordered (bulleted) lists.
+
+Unordered lists use asterisks, pluses, and hyphens -- interchangably
+-- as list markers:
+
+    *   Red
+    *   Green
+    *   Blue
+
+is equivalent to:
+
+    +   Red
+    +   Green
+    +   Blue
+
+and:
+
+    -   Red
+    -   Green
+    -   Blue
+
+Ordered lists use numbers followed by periods:
+
+    1.  Bird
+    2.  McHale
+    3.  Parish
+
+It's important to note that the actual numbers you use to mark the
+list have no effect on the HTML output Markdown produces. The HTML
+Markdown produces from the above list is:
+
+    <ol>
+    <li>Bird</li>
+    <li>McHale</li>
+    <li>Parish</li>
+    </ol>
+
+If you instead wrote the list in Markdown like this:
+
+    1.  Bird
+    1.  McHale
+    1.  Parish
+
+or even:
+
+    3. Bird
+    1. McHale
+    8. Parish
+
+you'd get the exact same HTML output. The point is, if you want to,
+you can use ordinal numbers in your ordered Markdown lists, so that
+the numbers in your source match the numbers in your published HTML.
+But if you want to be lazy, you don't have to.
+
+If you do use lazy list numbering, however, you should still start the
+list with the number 1. At some point in the future, Markdown may support
+starting ordered lists at an arbitrary number.
+
+List markers typically start at the left margin, but may be indented by
+up to three spaces. List markers must be followed by one or more spaces
+or a tab.
+
+To make lists look nice, you can wrap items with hanging indents:
+
+    *   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+        Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+        viverra nec, fringilla in, laoreet vitae, risus.
+    *   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+        Suspendisse id sem consectetuer libero luctus adipiscing.
+
+But if you want to be lazy, you don't have to:
+
+    *   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+    Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+    viverra nec, fringilla in, laoreet vitae, risus.
+    *   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+    Suspendisse id sem consectetuer libero luctus adipiscing.
+
+If list items are separated by blank lines, Markdown will wrap the
+items in `<p>` tags in the HTML output. For example, this input:
+
+    *   Bird
+    *   Magic
+
+will turn into:
+
+    <ul>
+    <li>Bird</li>
+    <li>Magic</li>
+    </ul>
+
+But this:
+
+    *   Bird
+
+    *   Magic
+
+will turn into:
+
+    <ul>
+    <li><p>Bird</p></li>
+    <li><p>Magic</p></li>
+    </ul>
+
+List items may consist of multiple paragraphs. Each subsequent
+paragraph in a list item must be intended by either 4 spaces
+or one tab:
+
+    1.  This is a list item with two paragraphs. Lorem ipsum dolor
+        sit amet, consectetuer adipiscing elit. Aliquam hendrerit
+        mi posuere lectus.
+
+        Vestibulum enim wisi, viverra nec, fringilla in, laoreet
+        vitae, risus. Donec sit amet nisl. Aliquam semper ipsum
+        sit amet velit.
+
+    2.  Suspendisse id sem consectetuer libero luctus adipiscing.
+
+It looks nice if you indent every line of the subsequent
+paragraphs, but here again, Markdown will allow you to be
+lazy:
+
+    *   This is a list item with two paragraphs.
+
+        This is the second paragraph in the list item. You're
+    only required to indent the first line. Lorem ipsum dolor
+    sit amet, consectetuer adipiscing elit.
+
+    *   Another item in the same list.
+
+To put a blockquote within a list item, the blockquote's `>`
+delimiters need to be indented:
+
+    *   A list item with a blockquote:
+
+        > This is a blockquote
+        > inside a list item.
+
+To put a code block within a list item, the code block needs
+to be indented *twice* -- 8 spaces or two tabs:
+
+    *   A list item with a code block:
+
+            <code goes here>
+
+
+It's worth noting that it's possible to trigger an ordered list by
+accident, by writing something like this:
+
+    1986. What a great season.
+
+In other words, a *number-period-space* sequence at the beginning of a
+line. To avoid this, you can backslash-escape the period:
+
+    1986\. What a great season.
+
+
+
+<h3 id="precode">Code Blocks</h3>
+
+Pre-formatted code blocks are used for writing about programming or
+markup source code. Rather than forming normal paragraphs, the lines
+of a code block are interpreted literally. Markdown wraps a code block
+in both `<pre>` and `<code>` tags.
+
+To produce a code block in Markdown, simply indent every line of the
+block by at least 4 spaces or 1 tab. For example, given this input:
+
+    This is a normal paragraph:
+
+        This is a code block.
+
+Markdown will generate:
+
+    <p>This is a normal paragraph:</p>
+
+    <pre><code>This is a code block.
+    </code></pre>
+
+One level of indentation -- 4 spaces or 1 tab -- is removed from each
+line of the code block. For example, this:
+
+    Here is an example of AppleScript:
+
+        tell application "Foo"
+            beep
+        end tell
+
+will turn into:
+
+    <p>Here is an example of AppleScript:</p>
+
+    <pre><code>tell application "Foo"
+        beep
+    end tell
+    </code></pre>
+
+A code block continues until it reaches a line that is not indented
+(or the end of the article).
+
+Within a code block, ampersands (`&`) and angle brackets (`<` and `>`)
+are automatically converted into HTML entities. This makes it very
+easy to include example HTML source code using Markdown -- just paste
+it and indent it, and Markdown will handle the hassle of encoding the
+ampersands and angle brackets. For example, this:
+
+        <div class="footer">
+            © 2004 Foo Corporation
+        </div>
+
+will turn into:
+
+    <pre><code><div class="footer">
+        &copy; 2004 Foo Corporation
+    </div>
+    </code></pre>
+
+Regular Markdown syntax is not processed within code blocks. E.g.,
+asterisks are just literal asterisks within a code block. This means
+it's also easy to use Markdown to write about Markdown's own syntax.
+
+
+
+<h3 id="hr">Horizontal Rules</h3>
+
+You can produce a horizontal rule tag (`<hr />`) by placing three or
+more hyphens, asterisks, or underscores on a line by themselves. If you
+wish, you may use spaces between the hyphens or asterisks. Each of the
+following lines will produce a horizontal rule:
+
+    * * *
+
+    ***
+
+    *****
+	
+    - - -
+
+    ---------------------------------------

+
+<h2 id="span">Span Elements</h2>
+
+<h3 id="link">Links</h3>
+
+Markdown supports two style of links: *inline* and *reference*.
+
+In both styles, the link text is delimited by [square brackets].
+
+To create an inline link, use a set of regular parentheses immediately
+after the link text's closing square bracket. Inside the parentheses,
+put the URL where you want the link to point, along with an *optional*
+title for the link, surrounded in quotes. For example:
+
+    This is [an example](http://example.com/ "Title") inline link.
+
+    [This link](http://example.net/) has no title attribute.
+
+Will produce:
+
+    <p>This is <a href="http://example.com/" title="Title">
+    an example</a> inline link.</p>
+
+    <p><a href="http://example.net/">This link</a> has no
+    title attribute.</p>
+
+If you're referring to a local resource on the same server, you can
+use relative paths:
+
+    See my [About](/about/) page for details.
+
+Reference-style links use a second set of square brackets, inside
+which you place a label of your choosing to identify the link:
+
+    This is [an example][id] reference-style link.
+
+You can optionally use a space to separate the sets of brackets:
+
+    This is [an example] [id] reference-style link.
+
+Then, anywhere in the document, you define your link label like this,
+on a line by itself:
+
+    [id]: http://example.com/  "Optional Title Here"
+
+That is:
+
+*   Square brackets containing the link identifier (optionally
+    indented from the left margin using up to three spaces);
+*   followed by a colon;
+*   followed by one or more spaces (or tabs);
+*   followed by the URL for the link;
+*   optionally followed by a title attribute for the link, enclosed
+    in double or single quotes.
+
+The link URL may, optionally, be surrounded by angle brackets:
+
+    [id]: <http://example.com/>  "Optional Title Here"
+
+You can put the title attribute on the next line and use extra spaces
+or tabs for padding, which tends to look better with longer URLs:
+
+    [id]: http://example.com/longish/path/to/resource/here
+        "Optional Title Here"
+
+Link definitions are only used for creating links during Markdown
+processing, and are stripped from your document in the HTML output.
+
+Link definition names may constist of letters, numbers, spaces, and punctuation -- but they are *not* case sensitive. E.g. these two links:
+
+	[link text][a]
+	[link text][A]
+
+are equivalent.
+
+The *implicit link name* shortcut allows you to omit the name of the
+link, in which case the link text itself is used as the name.
+Just use an empty set of square brackets -- e.g., to link the word
+"Google" to the google.com web site, you could simply write:
+
+	[Google][]
+
+And then define the link:
+
+	[Google]: http://google.com/
+
+Because link names may contain spaces, this shortcut even works for
+multiple words in the link text:
+
+	Visit [Daring Fireball][] for more information.
+
+And then define the link:
+	
+	[Daring Fireball]: http://daringfireball.net/
+
+Link definitions can be placed anywhere in your Markdown document. I
+tend to put them immediately after each paragraph in which they're
+used, but if you want, you can put them all at the end of your
+document, sort of like footnotes.
+
+Here's an example of reference links in action:
+
+    I get 10 times more traffic from [Google] [1] than from
+    [Yahoo] [2] or [MSN] [3].
+
+      [1]: http://google.com/        "Google"
+      [2]: http://search.yahoo.com/  "Yahoo Search"
+      [3]: http://search.msn.com/    "MSN Search"
+
+Using the implicit link name shortcut, you could instead write:
+
+    I get 10 times more traffic from [Google][] than from
+    [Yahoo][] or [MSN][].
+
+      [google]: http://google.com/        "Google"
+      [yahoo]:  http://search.yahoo.com/  "Yahoo Search"
+      [msn]:    http://search.msn.com/    "MSN Search"
+
+Both of the above examples will produce the following HTML output:
+
+    <p>I get 10 times more traffic from <a href="http://google.com/"
+    title="Google">Google</a> than from
+    <a href="http://search.yahoo.com/" title="Yahoo Search">Yahoo</a>
+    or <a href="http://search.msn.com/" title="MSN Search">MSN</a>.</p>
+
+For comparison, here is the same paragraph written using
+Markdown's inline link style:
+
+    I get 10 times more traffic from [Google](http://google.com/ "Google")
+    than from [Yahoo](http://search.yahoo.com/ "Yahoo Search") or
+    [MSN](http://search.msn.com/ "MSN Search").
+
+The point of reference-style links is not that they're easier to
+write. The point is that with reference-style links, your document
+source is vastly more readable. Compare the above examples: using
+reference-style links, the paragraph itself is only 81 characters
+long; with inline-style links, it's 176 characters; and as raw HTML,
+it's 234 characters. In the raw HTML, there's more markup than there
+is text.
+
+With Markdown's reference-style links, a source document much more
+closely resembles the final output, as rendered in a browser. By
+allowing you to move the markup-related metadata out of the paragraph,
+you can add links without interrupting the narrative flow of your
+prose.
+
+
+<h3 id="em">Emphasis</h3>
+
+Markdown treats asterisks (`*`) and underscores (`_`) as indicators of
+emphasis. Text wrapped with one `*` or `_` will be wrapped with an
+HTML `<em>` tag; double `*`'s or `_`'s will be wrapped with an HTML
+`<strong>` tag. E.g., this input:
+
+    *single asterisks*
+
+    _single underscores_
+
+    **double asterisks**
+
+    __double underscores__
+
+will produce:
+
+    <em>single asterisks</em>
+
+    <em>single underscores</em>
+
+    <strong>double asterisks</strong>
+
+    <strong>double underscores</strong>
+
+You can use whichever style you prefer; the lone restriction is that
+the same character must be used to open and close an emphasis span.
+
+Emphasis can be used in the middle of a word:
+
+    un*fucking*believable
+
+But if you surround an `*` or `_` with spaces, it'll be treated as a
+literal asterisk or underscore.
+
+To produce a literal asterisk or underscore at a position where it
+would otherwise be used as an emphasis delimiter, you can backslash
+escape it:
+
+    \*this text is surrounded by literal asterisks\*
+
+
+
+<h3 id="code">Code</h3>
+
+To indicate a span of code, wrap it with backtick quotes (`` ` ``).
+Unlike a pre-formatted code block, a code span indicates code within a
+normal paragraph. For example:
+
+    Use the `printf()` function.
+
+will produce:
+
+    <p>Use the <code>printf()</code> function.</p>
+
+To include a literal backtick character within a code span, you can use
+multiple backticks as the opening and closing delimiters:
+
+    ``There is a literal backtick (`) here.``
+
+which will produce this:
+
+    <p><code>There is a literal backtick (`) here.</code></p>
+
+The backtick delimiters surrounding a code span may include spaces --
+one after the opening, one before the closing. This allows you to place
+literal backtick characters at the beginning or end of a code span:
+
+	A single backtick in a code span: `` ` ``
+	
+	A backtick-delimited string in a code span: `` `foo` ``
+
+will produce:
+
+	<p>A single backtick in a code span: <code>`</code></p>
+	
+	<p>A backtick-delimited string in a code span: <code>`foo`</code></p>
+
+With a code span, ampersands and angle brackets are encoded as HTML
+entities automatically, which makes it easy to include example HTML
+tags. Markdown will turn this:
+
+    Please don't use any `<blink>` tags.
+
+into:
+
+    <p>Please don't use any <code><blink></code> tags.</p>
+
+You can write this:
+
+    `—` is the decimal-encoded equivalent of `—`.
+
+to produce:
+
+    <p><code>&#8212;</code> is the decimal-encoded
+    equivalent of <code>&mdash;</code>.</p>
+
+
+
+<h3 id="img">Images</h3>
+
+Admittedly, it's fairly difficult to devise a "natural" syntax for
+placing images into a plain text document format.
+
+Markdown uses an image syntax that is intended to resemble the syntax
+for links, allowing for two styles: *inline* and *reference*.
+
+Inline image syntax looks like this:
+
+    ![Alt text](/path/to/img.jpg)
+
+    ![Alt text](/path/to/img.jpg "Optional title")
+
+That is:
+
+*   An exclamation mark: `!`;
+*   followed by a set of square brackets, containing the `alt`
+    attribute text for the image;
+*   followed by a set of parentheses, containing the URL or path to
+    the image, and an optional `title` attribute enclosed in double
+    or single quotes.
+
+Reference-style image syntax looks like this:
+
+    ![Alt text][id]
+
+Where "id" is the name of a defined image reference. Image references
+are defined using syntax identical to link references:
+
+    [id]: url/to/image  "Optional title attribute"
+
+As of this writing, Markdown has no syntax for specifying the
+dimensions of an image; if this is important to you, you can simply
+use regular HTML `<img>` tags.
+
+
+* * *
+
+
+<h2 id="misc">Miscellaneous</h2>
+
+<h3 id="autolink">Automatic Links</h3>
+
+Markdown supports a shortcut style for creating "automatic" links for URLs and email addresses: simply surround the URL or email address with angle brackets. What this means is that if you want to show the actual text of a URL or email address, and also have it be a clickable link, you can do this:
+
+    <http://example.com/>
+    
+Markdown will turn this into:
+
+    <a href="http://example.com/">http://example.com/</a>
+
+Automatic links for email addresses work similarly, except that
+Markdown will also perform a bit of randomized decimal and hex
+entity-encoding to help obscure your address from address-harvesting
+spambots. For example, Markdown will turn this:
+
+    <address at example.com>
+
+into something like this:
+
+    <a href="&#x6D;&#x61;i&#x6C;&#x74;&#x6F;:&#x61;&#x64;&#x64;&#x72;&#x65;
+    ss@ex&#x61;m&#x70;&#x6C;e&#x2E;co
+    m">&#x61;&#x64;&#x64;&#x72;&#x65;ss@ex&#x61;
+    m&#x70;&#x6C;e&#x2E;com</a>
+
+which will render in a browser as a clickable link to "address at example.com".
+
+(This sort of entity-encoding trick will indeed fool many, if not
+most, address-harvesting bots, but it definitely won't fool all of
+them. It's better than nothing, but an address published in this way
+will probably eventually start receiving spam.)
+
+
+
+<h3 id="backslash">Backslash Escapes</h3>
+
+Markdown allows you to use backslash escapes to generate literal
+characters which would otherwise have special meaning in Markdown's
+formatting syntax. For example, if you wanted to surround a word with
+literal asterisks (instead of an HTML `<em>` tag), you can backslashes
+before the asterisks, like this:
+
+    \*literal asterisks\*
+
+Markdown provides backslash escapes for the following characters:
+
+    \   backslash
+    `   backtick
+    *   asterisk
+    _   underscore
+    {}  curly braces
+    []  square brackets
+    ()  parentheses
+    #   hash mark
+	+	plus sign
+	-	minus sign (hyphen)
+    .   dot
+    !   exclamation mark
+

+# kramdown Documentation
+
+## Overview
+
+kramdown is first and foremost a library for converting text written in a superset of Markdown to
+HTML. However, due to its modular architecture it is able to support additional input and output
+formats. The following input and output formats are currently supported:
+
+* Input: [kramdown](parser/kramdown.html) (a superset of Markdown),
+  [Markdown](parser/markdown.html), [Github Flavored Markdown](parser/gfm.html), [HTML](parser/html.html)
+
+* Output: [HTML](converter/html.html), [LaTeX](converter/latex.html),
+  [kramdown](converter/kramdown.html), [RemoveHtmlTags](converter/remove_html_tags.html) (a special
+  converter which removes HTML tags, normally used in conjunction with the LaTeX or kramdown
+  converters)
+
+The [kramdown syntax page](syntax.html) describes in detail what is supported and how it differs
+from standard Markdown.
+
+For all available options have a look at the [options documentation](options.html) or have a look at
+a parser/converter page to see which options they support!
+
+
+## Usage
+
+{:ruby: .language-ruby}
+
+The kramdown package provides two ways for using it:
+
+* **As a library**
+
+  kramdown uses basically the same API as [RedCloth], [BlueCloth] and [Maruku]:
+
+      require 'kramdown'
+
+      puts Kramdown::Document.new(text).to_html
+  {:ruby}
+
+  The second parameter to the `new` call is an options hash for (de)activating certain features. For
+  example, to disable automatic header ID generation, you can do the following:
+
+      puts Kramdown::Document.new(text, :auto_ids => false).to_html
+  {:ruby}
+
+  The default parser used is `kramdown`, however, you can select a different one with the `:input`
+  option:
+
+      puts Kramdown::Document.new(text, :input => 'html').to_latex
+  {:ruby}
+
+  You can also reuse the created document object to produce multiple outputs:
+
+      doc = Kramdown::Document.new(text, :input => 'html')
+      puts doc.to_html
+      puts doc.to_latex
+  {:ruby}
+
+  More information on how to use or extend kramdown can be found in the [API
+  documentation](rdoc/index.html)!
+
+* **As an application**
+
+  Together with the library files a binary called `kramdown` is shipped which can be used to convert
+  text in any supported input format to any supported output format. It either reads from the files
+  specified as the command line arguments or from the standard input. For example:
+
+      kramdown path/to/kramdown/doc/syntax.page
+
+  The input and output formats as well as all available kramdown options are supported through
+  command line switches.
+
+
+## Tests
+
+kramdown uses various test suites to verify the correct working of the parsers and converters. For
+more information, have a look at the [tests document](tests.html).

+## Overview
+
+If you want to get started with kramdown, have a look at the [installation page](installation.html)
+to see how you can install it on your system. Then look through the
+[documentation](documentation.html) for finding information about how to actually use kramdown and
+its parsers/converters. The [quick reference](quickref.html) provides a overview of the syntax -- if
+you need a more detailed description of the superset of Markdown which kramdown supports the [syntax
+page](syntax.html) is the place to go!

+
+## Thanks
+
+kramdown would not be possible without the prior work of many other people. I want to thank everyone
+involved with making Markdown such a nice markup language and especially the developers of other
+Markdown implementations because kramdown borrowed many ideas from existing packages.

+--- name:intro
+
+**kramdown** (sic, not Kramdown or KramDown, just kramdown) is a *free* MIT-licensed
+[Ruby](http://www.ruby-lang.org) library for parsing and converting a superset of Markdown. It is
+completely written in Ruby, supports standard Markdown (with some minor modifications) and various
+extensions that have been made popular by the [PHP Markdown Extra] package and [Maruku].
+
+It is probably the fastest pure-Ruby Markdown converter available (March 2013), being about 4x
+faster than [Maruku] and about 5x faster than [BlueFeather].

+# Download & Installation
+
+## Dependencies
+
+Since kramdown is written in Ruby, you just need the [Ruby interpreter](http://www.ruby-lang.org),
+version 1.8.5, 1.8.6, 1.8.7, 1.9.2, 1.9.3 or 2.0.0. There are no other dependencies.
+
+
+## Compatibility Notes
+
+kramdown should work on any platform which supports Ruby. It has been successfully tested on the
+following platforms:
+
+* Linux with Ruby 1.8.5, 1.8.6, 1.8.7, 1.9.2, 1.9.3, 2.0.0 and jruby 1.7.3.
+
+See the platform specific installation notes for more information!
+
+
+## Platform Specific Installation Instructions
+
+### Linux
+
+There are a variety of Linux distributions out there with different package management systems. So
+we will focus on instructions for Ubuntu 9.04 here (which should probably also work for any newer
+Ubuntu version or any recent Debian based distribution).
+
+After running the following commands, kramdown is installed and ready to use:
+
+    sudo aptitude install ruby rubygems
+    sudo gem install kramdown
+
+> You will also need to add `export PATH=$PATH:/var/lib/gems/1.9/bin` to your `~/.bashrc` because
+> this is the binary path the executable files get installed to.
+
+
+### Mac OS X
+
+Mac OS X Snow Leopard comes with Ruby and Rubygems preinstalled. So installing kramdown is as easy
+as running:
+
+    sudo gem install kramdown
+
+
+### Windows
+
+You need to install Ruby first. This can easily be done by using the [RubyInstaller] - just download
+the installation binary and run it. After that open a command shell (select `Start -> Run...`, then
+enter `cmd` and click on `Ok`) and type in the following:
+
+    gem install kramdown
+
+[RubyInstaller]: http://rubyinstaller.org
+
+
+## Generic Installation Instructions
+
+
+### Using Rubygems
+
+If you are using Rubygems, installing the latest version of kramdown is as simple as executing
+
+    gem install kramdown
+
+
+### Manual Installation
+
+The latest version of kramdown can always be downloaded as `.tar.gz` or `.zip` via the [Github
+releases page][ghreleases]. After the download the package needs to be decompressed and then you can
+install kramdown using the included `setup.rb` installation method:
+
+    $ ruby setup.rb config
+    $ ruby setup.rb setup
+    $ ruby setup.rb install
+
+[ghreleases]: https://github.com/gettalong/kramdown/releases
+
+
+### Using the repository version
+
+kramdown uses git as its versioning system and kramdown's repository is hosted on GitHub. The
+repository always contains a clean state of the current development version of kramdown. To check
+out kramdown use the following command:
+
+     git clone git://github.com/gettalong/kramdown.git

+# Quick Reference
+
+Below are examples of all available structural elements that can be used in a kramdown text. Since
+the kramdown syntax is a superset of the Markdown syntax, only a small part of the available syntax
+is not available in standard Markdown syntax. Note, that only the most basic syntax information is
+given. However, a link to the detailed syntax for each element is provided (which also details the
+differences to the standard Markdown syntax). The quick reference is for version **<%=
+::Kramdown::VERSION %>** of the syntax documentation.
+
+kramdown has two main classes of elements: block and span-level elements. Block-level elements are
+used to create paragraphs, headers, lists and so on whereas span-level elements are used to markup
+text phrases as emphasized, as a link and so on.
+
+All examples below feature the kramdown source, the converted HTML source (shown when hovering over
+the kramdown source) and the output as it appears in the browser. This looks like this:
+
+<table class="kdexample">
+<tr>
+<td><pre class="kdexample-before"><code>kramdown example code</code></pre></td>
+<td><pre class="kdexample-after-source"><code>Example code converted to HTML</code></pre>
+<div class="kdexample-after-live" style="clear:none">
+Live browser view of example code
+</div>
+</td>
+</tr>
+</table>
+
+
+# Block-level Elements - Main Structural Elements
+
+## Paragraphs
+
+{kdlink: {oid: paragraphs, part: "paragraphs"}}
+
+Consecutive lines of text are considered to be one paragraph. As with other block level elements you
+have to add a blank line to separate it from the following block-level element:
+
+{kdexample::}
+The first paragraph.
+
+Another paragraph
+{kdexample}
+
+Explicit line breaks in a paragraph can be made by using two spaces or two backslashes at the end of a line:
+
+{kdexample::}
+This is a paragraph  
+which contains a hard line break.
+{kdexample}
+
+
+## Headers
+
+{kdlink: {oid: headers, part: "headers"}}
+
+kramdown supports Setext style headers and atx style headers. A header must always be preceded by a
+blank line except at the beginning of the document:
+
+
+{kdexample::}
+First level header
+==================
+
+Second level header
+-------------------
+{kdexample}
+
+{kdexample::}
+# H1 header
+
+## H2 header
+
+### H3 header
+
+#### H4 header
+
+##### H5 header
+
+###### H6 header
+{kdexample}
+
+If you set the option `auto_ids` to `false` (for example, by using the `options` extension, see
+[Extensions](#extensions)), then the automatic header ID generation is turned off:
+
+{kdexample::}
+{::options auto_ids="false" /}
+
+# A header without an ID
+{kdexample}
+
+
+## Blockquotes
+
+{kdlink: {oid: blockquotes, part: "blockquotes"}}
+
+A blockquote is started using the `>` marker followed by an optional space; all following lines that
+are also started with the blockquote marker belong to the blockquote. You can use any block-level
+elements inside a blockquote:
+
+{kdexample::}
+> A sample blockquote.
+>
+> >Nested blockquotes are
+> >also possible.
+>
+> ## Headers work too
+> This is the outer quote again.
+{kdexample}
+
+You may also be lazy with the `>` markers as long as there is no blank line:
+
+{kdexample::}
+> This is a blockquote
+continued on this
+and this line.
+
+But this is a separate paragraph.
+{kdexample}
+
+## Code Blocks
+
+{kdlink: {oid: code-blocks, part: "code blocks"}}
+
+kramdown supports two different code block styles. One uses lines indented with either four spaces
+or one tab whereas the other uses lines with tilde characters as delimiters -- therefore the content
+does not need to be indented:
+
+{kdexample::}
+    This is a sample code block.
+
+    Continued here.
+{kdexample}
+
+{kdexample::}
+~~~~~~
+This is also a code block.
+~~~
+Ending lines must have at least as
+many tildes as the starting line.
+~~~~~~~~~~~~
+{kdexample}
+
+The following is a code block with a language specified:
+
+{kdexample::}
+~~~ ruby
+def what?
+  42
+end
+~~~
+{kdexample}
+
+
+## Horizontal Rules
+
+{kdlink: {oid: horizontal-rules, part: "horizontal rules"}}
+
+It is easy to insert a horizontal rule in kramdown: just use three or more asterisks, dashes or
+underscores, optionally separated by spaces or tabs, on an otherwise blank line:
+
+{kdexample::}
+* * *
+
+\---
+
+  _  _  _  _
+
+---------------
+{kdexample}
+
+
+## Lists
+
+{kdlink: {oid: lists, part: "lists"}}
+
+kramdown supports ordered and unordered lists. Ordered lists are started by using a number followed
+by a period, a space and then the list item text. The content of a list item consists of block-level
+elements. All lines which have the same indent as the text of the line with the list marker belong
+to the list item:
+
+{kdexample::}
+1. This is a list item
+2. And another item
+2. And the third one
+   with additional text
+{kdexample}
+
+As with block quotes, you may be lazy when using the list item marker:
+
+{kdexample::}
+* A list item
+with additional text
+{kdexample}
+
+As the content consists of block-level elements you can do things like the following:
+
+{kdexample::}
+1.  This is a list item
+
+    > with a blockquote
+
+    # And a header
+
+2.  Followed by another item
+{kdexample}
+
+Nested lists are also easy to create:
+
+{kdexample::}
+1. Item one
+   1. sub item one
+   2. sub item two
+   3. sub item three
+2. Item two
+{kdexample}
+
+Lists can occur directly after other block-level elements, however, there has to be at least one
+blank line if you want to follow a paragraph with a list:
+
+{kdexample::}
+This is a paragraph.
+1. This is NOT a list.
+
+1. This is a list!
+{kdexample}
+
+Unordered lists are started by using an asterisk, a dash or a plus sign (they can be mixed) and a
+space. Apart from that unordered lists follow the same rules as ordered lists:
+
+{kdexample::}
+* Item one
++ Item two
+- Item three
+{kdexample}
+
+## Definition Lists
+
+{kdlink: {oid: definition-lists, part: "definition lists"}}
+
+A definition list works similar to a normal list and is used to associate definitions with terms.
+Definition lists are started when a normal paragraph is followed by a line starting with a colon and
+then the definition text. One term can have many definitions and multiple terms can have the same
+definition. Each line of the preceding paragraph is assumed to contain one term, for example:
+
+{kdexample::}
+term
+: definition
+: another definition
+
+another term
+and another term
+: and a definition for the term
+{kdexample}
+
+If you insert a blank line before a definition (note: there must only be one blank line between the
+terms and the first definition), the definition will be wrapped in a paragraph:
+
+{kdexample::}
+term
+
+: definition
+: definition
+{kdexample}
+
+Each term can be styled using span-level elements and each definition is parsed as block-level
+elements, i.e. you can use any block-level in a definition. Just use the same indent for the lines
+following the definition line:
+
+{kdexample::}
+This *is* a term
+
+: This will be a para
+
+  > a blockquote
+
+  # A header
+{kdexample}
+
+
+## Tables
+
+{kdlink: {oid: tables, part: "tables"}}
+
+kramdown supports a syntax for creating simple tables. A line starting with a pipe character (`|`)
+starts a table row. However, if the pipe characters is immediately followed by a dash (`-`), a
+separator line is created. Separator lines are used to split the table header from the table body
+(and optionally align the table columns) and to split the table body into multiple parts. If the
+pipe character is followed by an equal sign (`=`), the tables rows below it are part of the table
+footer.
+
+{kdexample::}
+| A simple | table |
+| with multiple | lines|
+{kdexample}
+
+{kdexample::}
+| Header1 | Header2 | Header3 |
+|:--------|:-------:|--------:|
+| cell1   | cell2   | cell3   |
+| cell4   | cell5   | cell6   |
+|----
+| cell1   | cell2   | cell3   |
+| cell4   | cell5   | cell6   |
+|=====
+| Foot1   | Foot2   | Foot3
+{: rules="groups"}
+{kdexample}
+
+
+## HTML elements
+
+{kdlink: {oid: html-blocks, part: "HTML blocks"}}
+
+kramdown allows you to use block-level HTML tags (`div`, `p`, `pre`, ...) to markup whole blocks of
+text -- just start a line with a block-level HTML tag. kramdown syntax is normally not processed
+inside an HTML tag but this can be changed with the `parse_block_html` option. If this options is
+set to `true`, then the content of a block-level HTML tag is parsed by kramdown either as block
+level or span-level text, depending on the tag:
+
+{kdexample::}
+<div style="float: right">
+Something that stays right and is not wrapped in a para.
+</div>
+
+{::options parse_block_html="true" /}
+
+<div>
+This is wrapped in a para.
+</div>
+<p>
+This can contain only *span* level elements.
+</p>
+{kdexample}
+
+
+## Block Attributes
+
+{kdlink: {oid: block-ials, part: "block IALs"}}
+{kdlink: {oid: attribute-list-definitions, part: "ALDs"}}
+
+You can assign any attribute to a block-level element. Just directly follow the block with a *block
+inline attribute list* (or short: block IAL). A block IAL consists of a left curly brace, followed
+by a colon, the attribute definitions and a right curly brace. Here is a simple example which sets the
+`title` attribute of a block quote:
+
+{kdexample::}
+> A nice blockquote
+{: title="Blockquote title"}
+{kdexample}
+
+As one often wants to set one or more CSS classes on an element, there is an easy shortcut:
+
+{kdexample::}
+> A nice blockquote
+{: .class1 .class2}
+{kdexample}
+
+A shortcut for setting the ID is also provided. Just prefix the ID with a hash symbol:
+
+{kdexample::}
+> A nice blockquote
+{: #with-an-id}
+{kdexample}
+
+Sometimes one wants to use the same attributes for many elements. kramdown allows you to define the
+attributes in one place with an *attribute list definition* (or short: ALD) and just reference this
+definition in a block IAL. An ALD has the same structure as a block IAL but the colon has to be
+replace with a colon, the reference name and another colon. By just using the reference name as-is
+in a block IAL, one can include the attributes of the referenced ALD:
+
+{kdexample::}
+{:refdef: .c1 #id .c2 title="title"}
+paragraph
+{: refdef}
+{kdexample}
+
+The order in a block IAL or ALD is important because later defined attributes overwrite (with the
+exception of the shortcut for CSS classes) prior defined attributes:
+
+{kdexample::}
+{:refdef: .c1 #id .c2 title="title"}
+paragraph
+{: refdef .c3 title="t" #para}
+{kdexample}
+
+
+## Extensions
+
+{kdlink: {oid: extensions, part: "extensions"}}
+
+kramdown provides some less used functionality through a common syntax. This will allow the easy
+addition of other extensions if need arises. Currently, there are extensions for ignoring text (i.e.
+treating text as comment), for inserting arbitrary text as-is into the output and for setting
+kramdown options.
+
+Here is an example that shows how to insert comments into text:
+
+{kdexample::}
+This is a paragraph
+{::comment}
+This is a comment which is
+completely ignored.
+{:/comment}
+... paragraph continues here.
+
+Extensions can also be used
+inline {::nomarkdown}**see**{:/}!
+{kdexample}
+
+As one can see from the above example, the syntax for extensions is nearly identical to that of
+ALDs. However, there is no trailing colon after the extension name and the extension end tag needs a
+slash between the colon and the extension name. One can also use the short form of the end tag, i.e.
+`{:/}`. Attribute definitions can be specified on the start tag by separating them with a space from
+the extension name. Also, if the extension does not have a body, there needs to be a slash right
+before the closing brace:
+
+{kdexample::}
+{::options auto_ids="false" /}
+
+# Header without id
+{kdexample}
+
+
+
+
+# Span-Level Elements - Text Modifiers
+
+## Emphasis
+
+{kdlink: {oid: emphasis, part: "emphasis"}}
+
+Emphasis can be added to text by surrounding the text with either asterisks or underscores:
+
+{kdexample::}
+This is *emphasized*,
+_this_ too!
+{kdexample}
+
+Strong emphasis can be done by doubling the delimiters:
+
+{kdexample::}
+This is **strong**,
+__this__ too!
+{kdexample}
+
+The form with the asterisks can also be used to markup parts of words:
+
+{kdexample::}
+This w**ork**s as expected!
+{kdexample}
+
+
+## Links and Images
+
+{kdlink: {oid: links-and-images, part: "links and images"}}
+
+A simple link can be created by surrounding the text with square brackets and the link URL with
+parentheses:
+
+{kdexample::}
+A [link](http://kramdown.gettalong.org)
+to the kramdown homepage.
+{kdexample}
+
+You can also add title information to the link:
+
+{kdexample::}
+A [link](http://kramdown.gettalong.org "hp")
+to the homepage.
+{kdexample}
+
+There is another way to create links which does not interrupt the text flow. The URL and title are
+defined using a reference name and this reference name is then used in square brackets instead of
+the link URL:
+
+{kdexample::}
+A [link][kramdown hp]
+to the homepage.
+
+[kramdown hp]: http://kramdown.gettalong.org "hp"
+{kdexample}
+
+If the link text itself is the reference name, the second set of square brackets can be omitted:
+
+{kdexample::}
+A link to the [kramdown hp].
+
+[kramdown hp]: http://kramdown.gettalong.org "hp"
+{kdexample}
+
+Images can be created in a similar way: just use an exclamation mark before the square brackets. The
+link text will become the alternative text of the image and the link URL specifies the image source:
+
+{kdexample::}
+An image: ![gras](img/image.jpg)
+{kdexample}
+
+
+## Inline Code
+
+{kdlink: {oid: code-spans, part: "code spans"}}
+
+Text phrases can be easily marked up as code by surrounding them with backticks:
+
+{kdexample::}
+Use `Kramdown::Document.new(text).to_html`
+to convert the `text` in kramdown
+syntax to HTML.
+{kdexample}
+
+If you want to use literal backticks in your code, just use two or more backticks as delimiters. The
+space right after the beginning delimiter and the one right before the closing delimiter are ignore:
+
+{kdexample::}
+Use backticks to markup code,
+e.g. `` `code` ``.
+{kdexample}
+
+
+## Footnotes
+
+{kdlink: {oid: footnotes, part: "footnotes"}}
+
+Footnotes can easily be used in kramdown. Just set a footnote marker (consists of square brackets
+with a caret and the footnote name inside) in the text and somewhere else the footnote definition (which
+basically looks like a reference link definition):
+
+{kdexample::}
+This is a text with a
+footnote[^1].
+
+[^1]: And here is the definition.
+{kdexample}
+
+The footnote definition can contain any block-level element, all lines following a footnote
+definition indented with four spaces or one tab belong to the definition:
+
+{kdexample::}
+This is a text with a
+footnote[^2].
+
+[^2]:
+    And here is the definition.
+
+    > With a quote!
+{kdexample}
+
+As can be seen above the footnote name is only used for the anchors and the numbering is done
+automatically in document order.  Repeated footnote markers will link to the same footnote
+definition.
+
+
+## Abbreviations
+
+{kdlink: {oid: abbreviations, part: "abbreviations"}}
+
+Abbreviations will work out of the box once you add an abbreviation definition. So you can just
+write the text and add the definitions later on.
+
+{kdexample::}
+This is an HTML
+example.
+
+*[HTML]: Hyper Text Markup Language
+{kdexample}
+
+
+## HTML Elements
+
+{kdlink: {oid: html-spans, part: "HTML spans"}}
+
+HTML is not only supported on the block-level but also on the span-level:
+
+{kdexample::}
+This is <span style="color: red">written in
+red</span>.
+{kdexample}
+
+
+## Inline Attributes
+
+{kdlink: {oid: span-ials, part: "span IALs"}}
+
+As with a block-level element you can assign any attribute to a span-level elements using a *span
+inline attribute list* (or short: span IAL). A span IAL has the same syntax as a block IAL and must
+immediately follow the span-level element:
+
+{kdexample::}
+This is *red*{: style="color: red"}.
+{kdexample}

+
+# kramdown Syntax
+
+This is version **<%= ::Kramdown::VERSION %>** of the syntax documentation.
+
+The kramdown syntax is based on the Markdown syntax and has been enhanced with features that are
+found in other Markdown implementations like [Maruku], [PHP Markdown Extra] and [Pandoc]. However,
+it strives to provide a strict syntax with definite rules and therefore isn't completely compatible
+with Markdown. Nonetheless, most Markdown documents should work fine when parsed with kramdown. All
+places where the kramdown syntax differs from the Markdown syntax are highlighted.
+
+Following is the complete syntax definition for all elements kramdown supports. Together with the
+documentation on the available converters, it is clearly specified what you will get when a kramdown
+document is converted.
+
+
+## Source Text Formatting
+
+A kramdown document may be in any encoding, for example ASCII, UTF-8 or ISO-8859-1, and the output
+will have the same encoding as the source.
+
+The document consists of two types of elements, block-level elements and span-level elements:
+
+* Block-level elements define the main structure of the content, for example, what part of the text
+  should be a paragraph, a list, a blockquote and so on.
+
+* Span-level elements mark up small text parts as, for example, emphasized text or a link.
+
+Thus span-level elements can only occur inside block-level elements or other span-level elements.
+
+You will often find references to the "first column" or "first character" of a line in a block-level
+element descriptions. Such a reference is always to be taken relative to the current indentation
+level because some block-level elements open up a new indentation level (e.g. blockquotes). The
+beginning of a kramdown document opens up the default indentation level which begins at the first
+column of the text.
+
+
+### Line Wrapping
+
+Some lightweight markup syntax don't work well in environments where lines are hard-wrapped. For
+example, this is the case with many email programs. Therefore kramdown allows content like
+paragraphs or blockquotes to be hard-wrapped, i.e. broken across lines. This is sometimes referred
+to as "lazy syntax" since the indentation or line prefix required for the first line of content is
+not required for the consecutive lines.
+
+Block-level elements that support line wrapping always end when one of the following conditions is
+met:
+
+* a [blank line](#blank-lines), an [EOB marker line](#eob-marker), a [block IAL](#block-ials) or the
+  end of the document (i.e. a [block boundary](#block-boundaries)),
+
+*  or an [HTML block](#html-blocks).
+
+Line wrapping is allowed throughout a kramdown document but there are some block-level elements that
+do *not* support being hard-wrapped:
+
+[headers](#headers)
+
+: This is not an issue in most situations since headers normally fit on one line. If a header text
+  gets too long for one line, you need to use HTML syntax instead.
+
+[fenced code blocks](#fenced-code-blocks)
+
+: The delimiting lines of a fenced code block do not support hard-wrapping. Since everything between
+  the delimiting lines is taken as is, the content of a fenced code block does also not support
+  hard-wrapping.
+
+[definition list terms](#definition-lists)
+
+: Each definition term has to appear on a separate line. Hard-wrapping would therefore introduce
+  additional definition terms. The definitions themselves, however, do support hard-wrapping.
+
+[tables](#tables)
+
+: Since each line of a kramdown table describes one table row or a separator, it is not possible to
+  hard-wrap tables.
+
+**Note** that it is **NOT** recommended to use lazy syntax to write a kramdown document. The
+flexibility that the kramdown syntax offers due to the issue of line wrapping hinders readability
+and should therefore not be used.
+
+
+### Usage of Tabs
+
+kramdown assumes that tab stops are set at multiples of four. This is especially important when
+using tabs for indentation in lists. Also, tabs may only be used at the beginning of a line when
+indenting text and must not be preceded by spaces. Otherwise the results may be unexpected.
+
+
+### Automatic and Manual Escaping
+
+Depending on the output format, there are often characters that need special treatment. For example,
+when converting a kramdown document to HTML one needs to take care of the characters `<`, `>` and
+`&`. To ease working with these special characters, they are automatically and correctly escaped
+depending on the output format.
+
+This means, for example, that you can just use `<`, `>` and `&` in a kramdown document and need not
+think about when to use their HTML entity counterparts. However, if you *do use* HTML entities or
+HTML tags which use one of the characters, the result will be correct nonetheless!
+
+Since kramdown also uses some characters to mark-up the text, there needs to be a way to escape
+these special characters so that they can have their normal meaning. This can be done by using
+backslash escapes. For example, you can use a literal back tick like this:
+
+    This \`is not a code\` span!
+
+Following is a list of all the characters (character sequences) that can be escaped:

+    "         double quote
+    '         single quote
+    $         dollar sign
+
+
+## Block Boundaries
+
+Some block-level elements have to start and/or end on so called block boundaries, as stated in their
+documentation. There are two cases where block boundaries come into play:
+
+* If a block-level element has to start on a block boundary, it has to be preceded by either a
+  [blank line](#blank-lines), an [EOB marker](#eob-marker), a [block IAL](#block-ials) or it has to
+  be the first element.
+
+* If a block-level element has to end on a block boundary, it has to be followed by either a [blank
+  line](#blank-lines), an [EOB marker](#eob-marker), a [block IAL](#block-ials) or it has to be the
+  last element.
+
+
+
+# Structural Elements
+
+All structural elements are block-level elements and they are used to structure the content. They
+can mark up some text as, for example, a simple paragraph, a quote or as a list item.
+
+
+## Blank lines
+
+Any line that just contains white space characters such as spaces and tabs is considered a blank
+line by kramdown. One or more consecutive blank lines are handled as one empty blank line. Blank
+lines are used to separate block-level elements from each other and in this case they don't have
+semantic meaning. However, there are some cases where blank lines do have a semantic meaning:
+
+* When used in headers -- see the [headers section](#headers)
+* When used in code blocks -- see the [code blocks section](#code-blocks)
+* When used in lists -- see the [lists section](#lists)
+* When used in math blocks -- see the [math blocks section](#math-blocks)
+* When used for elements that have to start/end on [block boundaries](#block-boundaries)
+
+
+## Paragraphs
+
+Paragraphs are the most used block-level elements. One or more consecutive lines of text are
+interpreted as one paragraph. The first line of a paragraph may be indented up to three spaces, the
+other lines can have any amount of indentation because paragraphs support [line
+wrapping](#line-wrapping). In addition to the rules outlined in the section about line wrapping, a
+paragraph ends when a [definition list line](#definition-lists) is encountered.
+
+You can separate two consecutive paragraphs from each other by using one or more blank lines. Notice
+that a line break in the source does not mean a line break in the output (due to the [lazy
+syntax](#line-wrapping))!. If you want to have an explicit line break (i.e. a `<br />` tag) you need
+to end a line with two or more spaces or two backslashes! Note, however, that a line break on the
+last text line of a paragraph is not possible and will be ignored. Leading and trailing spaces will
+be stripped from the paragraph text.
+
+The following gives you an example of how paragraphs look like:
+
+    This para line starts at the first column. However,
+          the following lines can be indented any number of spaces/tabs.
+       The para continues here.
+
+      This is another paragraph, not connected to the above one. But  
+    with a hard line break. \\
+    And another one.
+{: .show-whitespaces .ws-lr}
+
+
+## Headers
+
+kramdown supports so called Setext style and atx style headers. Both forms can be used inside a
+single document.
+
+### Setext Style
+
+Setext style headers have to start on a [block boundary](#block-boundaries) with a line of text (the
+header text) and a line with only equal signs (for a first level header) or dashes (for a second
+level header). The header text may be indented up to three spaces but any leading or trailing spaces
+are stripped from the header text. The amount of equal signs or dashes is not significant, just one
+is enough but more may look better. The equal signs or dashes have to begin at the first column. For
+example:
+
+    First level header
+    ==================
+
+    Second level header
+    ------
+
+       Other first level header
+    =
+
+Since Setext headers start on block boundaries, this means in most situations that they have to be
+preceded by a blank line. However, blank lines are not necessary after a Setext header:
+
+    This is a normal
+    paragraph.
+
+    And A Header
+    ------------
+    And a paragraph
+
+    > This is a blockquote.
+
+    And A Header
+    ------------
+
+However, it is generally a good idea to also use a blank line after a Setext header because it looks
+more appropriate and eases reading of the document.
+
+> The original Markdown syntax allows one to omit the blank line before a Setext header. However,
+> this leads to ambiguities and makes reading the document harder than necessary. Therefore it is
+> not allowed in a kramdown document.
+{: .markdown-difference}
+
+An edge case worth mentioning is the following:
+
+    header
+    ---
+    para
+
+One might ask if this represents two paragraphs separated by a [horizontal rule](#horizontal-rules)
+or a second level header and a paragraph. As suggested by the wording in the example, the latter is
+the case. The general rule is that Setext headers are processed before horizontal rules.
+
+### atx Style
+
+atx style headers have to start on a [block boundary](#block-boundaries) with a line that contains
+one or more hash characters and then the header text. No spaces are allowed before the hash
+characters. The number of hash characters specifies the heading level: one hash character gives you
+a first level heading, two a second level heading and so on until the maximum of six hash characters
+for a sixth level heading. You may optionally use any number of hashes at the end of the line to
+close the header. Any leading or trailing spaces are stripped from the header text. For example:
+
+    # First level header
+
+    ### Third level header    ###
+
+    ## Second level header ######
+
+> Again, the original Markdown syntax allows one to omit the blank line before an atx style header.
+{: .markdown-difference}
+
+
+### Specifying a Header ID
+
+kramdown supports a nice way for explicitly setting the header ID which is taken from [PHP Markdown
+Extra] and [Maruku]: If you follow the header text with an opening curly bracket (separated from the
+text with a least one space), a hash, the ID and a closing curly bracket, the ID is set on the
+header. If you use the trailing hash feature of atx style headers, the header ID has to go after the
+trailing hashes. For example:
+
+    Hello        {#id}
+    -----
+
+    # Hello      {#id}
+
+    # Hello #    {#id}
+
+> This additional syntax is not part of standard Markdown.
+{: .markdown-difference}
+
+
+## Blockquotes
+
+A blockquote is started using the `>` marker followed by an optional space and the content of the
+blockquote. The marker itself may be indented up to three spaces. All following lines, whether they
+are started with the blockquote marker or just contain text, belong to the blockquote because
+blockquotes support [line wrapping](#line-wrapping).
+
+The contents of a blockquote are block-level elements. This means that if you are just using text as
+content that it will be wrapped in a paragraph. For example, the following gives you one blockquote
+with two paragraphs in it:
+
+    > This is a blockquote.
+    >     on multiple lines
+    that may be lazy.
+    >
+    > This is the second paragraph.
+
+Since the contents of a blockquote are block-level elements, you can nest blockquotes and use other
+block-level elements (this is also the reason why blockquotes need to support line wrapping):
+
+    > This is a paragraph.
+    >
+    > > A nested blockquote.
+    >
+    > ## Headers work
+    >
+    > * lists too
+    >
+    > and all other block-level elements
+
+Note that the first space character after the `>` marker does *not* count when counting spaces for
+the indentation of the block-level elements inside the blockquote! So [code blocks](#code-blocks)
+will have to be indented with five spaces or one space and one tab, like this:
+
+    > A code block:
+    >
+    >     ruby -e 'puts :works'
+
+[Line wrapping](#line-wrapping) allows one to be lazy but hinders readability and should therefore
+be avoided, especially with blockquotes. Here is an example of using blockquotes with line wrapping:
+
+    > This is a paragraph inside
+    a blockquote.
+    >
+    > > This is a nested paragraph
+    that continues here
+    > and here
+    > > and here
+
+
+## Code Blocks
+
+Code blocks can be used to represent verbatim text like markup, HTML or a program fragment because
+no syntax is parsed within a code block.
+
+### Standard Code Blocks
+
+A code block can be started by using four spaces or one tab and then the text of the code block. All
+following lines containing text, whether they adhere to this syntax or not, belong to the code block
+because code blocks support [line wrapping](#line-wrapping)). A wrapped code line is automatically
+appended to the preceding code line by substituting the line break with a space character. The
+indentation (four spaces or one tab) is stripped from each line of the code block.
+
+> The original Markdown syntax does not allow line wrapping in code blocks.
+{: .markdown-difference}
+
+Note that consecutive code blocks that are only separate by [blank lines](#blank-lines) are merged
+together into one code block:
+
+        Here comes some code
+
+        This text belongs to the same code block.
+
+If you want to have one code block directly after another one, you need to use an [EOB
+marker](#eob-marker) to separate the two:
+
+        Here comes some code
+    ^
+        This one is separate.
+
+### Fenced Code Blocks
+
+> This alternative syntax is not part of the original Markdown syntax. The idea and syntax comes
+> from the [PHP Markdown Extra] package.
+{: .markdown-difference}
+
+kramdown also supports an alternative syntax for code blocks which does not use indented blocks but
+delimiting lines. The starting line needs to begin with three or more tilde characters (`~`) and the
+closing line needs to have at least the number of tildes the starting line has. Everything between
+is taken literally as with the other syntax but there is no need for indenting the text. For
+example:
+
+    ~~~~~~~~
+    Here comes some code.
+    ~~~~~~~~
+
+If you need lines of tildes in such a code block, just start the code block with more tildes. For
+example:
+
+    ~~~~~~~~~~~~
+    ~~~~~~~
+    code with tildes
+    ~~~~~~~~
+    ~~~~~~~~~~~~~~~~~~
+
+This type of code block is especially useful for copy-pasted code since you don't need to indent the
+code.
+
+### Language of Code Blocks
+
+You can tell kramdown the language of a code block by using an [IAL](#inline-attribute-lists):
+
+    ~~~
+    def what?
+      42
+    end
+    ~~~
+    {: .language-ruby}
+
+The specially named class `language-ruby` tells kramdown that this code block is written in the Ruby
+language. Such information can be used, for example, by converters to do syntax highlighting on the
+code block.
+
+Fenced code blocks provide an easier way to specify the language, namely by appending the language
+of the code block to the end of the starting line:
+
+    ~~~ ruby
+    def what?
+      42
+    end
+    ~~~
+
+
+## Lists
+
+kramdown provides syntax elements for creating ordered and unordered lists as well as definition
+lists.
+
+### Ordered and Unordered lists
+
+Both ordered and unordered lists follow the same rules.
+
+A list is started with a list marker (in case of unordered lists one of `+`, `-` or `*` -- you can
+mix them -- and in case of ordered lists a number followed by a period) followed by one tab or at
+least one space, optionally followed by an [IAL](#inline-attribute-lists) that should be applied to
+the list item and then the first part of the content of the list item. The leading tabs or spaces
+are stripped away from this first line of content to allow for a nice alignment with the following
+content of a list item (see below). All following list items with the same marker type (unordered or
+ordered) are put into the same list. The numbers used for ordered lists are irrelevant, an ordered
+list always starts at 1.
+
+The following gives you an unordered list and an ordered list:
+
+    * kram
+    + down
+    - now
+
+    1. kram
+    2. down
+    3. now
+
+> The original Markdown syntax allows the markers of ordered and unordered lists to be mixed, the
+> first marker specifying the list type (ordered or unordered). This is not allowed in kramdown. As
+> stated, the above example will give you two lists (an unordered and an ordered) in kramdown and
+> only one unordered list in Markdown.
+{: .markdown-difference}
+
+The first list marker in a list may be indented up to three spaces. The column number of the first
+non-space character which appears after the list item marker on the same line specifies the
+indentation that has to be used for the following lines of content of the list item. If there is no
+such character, the indentation that needs to be used is four spaces or one tab. Indented lines may
+be followed by lines containing text with any amount of indentation due to [line
+wrapping](#line-wrapping). Note, however, that in addition to the rules outlined in the section
+about line wrapping, a list item also ends when a line with another list item marker is encountered
+-- see the next paragraph.
+
+The indentation is stripped from the content and the content (note that the content naturally also
+contains the content of the line with the item marker) is processed as text containing block-level
+elements. All other list markers in the list may be indented up to three spaces or the number of
+spaces used for the indentation of the last list item minus one, whichever number is smaller. For
+example:
+
+    * This is the first line. Since the first non-space characters appears in
+      column 3, all other indented lines have to be indented 2 spaces.
+    However, one could be lazy and not indent a line but this is not
+    recommended.
+    *       This is the another item of the list. It uses a different number
+       of spaces for indentation which is okay but should generally be avoided.
+       * The list item marker is indented 3 spaces which is allowed but should
+         also be avoided and starts the third list item. Note that the lazy
+         line in the second list item may make you believe that this is a
+         sub-list which it isn't! So avoid being lazy!
+
+So, while the above is possible and creates one list with three items, it is not advised to use
+different (marker and list content) indents for same level list items as well as lazy indentation!
+It is much better to write such a list in the following way:
+
+    * This is the first list item bla blabla blabla blabla blabla blabla
+      blabla blabla blabla blabla blabla blabla blabla blabla blabla blabla
+      blabla blabla blabla bla
+    * This is the another item of the list. bla blabla blabla blabla blabla
+      blabla blabla blabla blabla blabla blabla blabla blabla blabla blabla
+
+> The original Markdown syntax also allows you to indent the marker, however, the behaviour of what
+> happens with the list items is not clearly specified and may surprise you.
+>
+> Also, Markdown uses a fixed number of spaces/tabs to indent the lines that belong to a list item!
+{: .markdown-difference}
+
+When using tabs for indenting the content of a list item, remember that tab stops occur at multiples
+of four for kramdown. Tabs are correctly converted to spaces for calculating the indentation. For
+example:
+
+    *   Using a tab to indent this line, the tab only counts as three spaces
+        and therefore the overall indentation is four spaces.
+
+       1.   The tab after the marker counts here as three spaces. Since the
+            indentation of the marker is three spaces and the marker itself
+            takes two characters, the overall indentation needed for the
+            following lines is eight spaces or two tabs.
+
+It is clear that you might get unexpected results if you mix tabs and spaces or if you don't have
+the tab stops set to multiples of four in your editor! Therefore this should be avoided!
+
+The content of a list item is made up of either text or block-level elements. Simple list items only
+contain text like in the above examples. They are not even wrapped in a paragraph tag. If the first
+list text is followed by one or more blank lines, it will be wrapped in a paragraph tag:
+
+    * kram
+
+    * down
+    * now
+
+In the above example, the first list item text will be wrapped in a paragraph tag since it is
+followed by a blank line whereas the second list item contains just text. There is obviously a
+problem for doing this with the last list item when it contains only text. You can circumvent this
+by leaving a blank line after the last list item and using an EOB marker:
+
+    * Not wrapped in a paragraph
+    * Wrapped in a paragraph due to the following blank line.
+
+    * Also wrapped in a paragraph due to the
+      following blank line and the EOB marker.
+
+    ^
+
+The text of the last list item is also wrapped in a paragraph tag if *all* other list items contain
+a proper paragraph as first element. This makes the following use case work like expected, i.e.
+*all* the list items are wrapped in paragraphs:
+
+    * First list item
+
+    * Second list item
+
+    * Last list item
+
+> The original Markdown syntax page specifies that list items which are separated by one or more
+> blank lines are wrapped in paragraph tags. This means that the first text will also be wrapped in
+> a paragraph if you have block-level elements in a list which are separated by blank lines. The
+> above rule is easy to remember and lets you exactly specify when the first list text should be
+> wrapped in a paragraph. The idea for the above rule comes from the [Pandoc] package.
+{: .markdown-difference}
+
+As seen in the examples above, blank lines between list items are allowed.
+
+Since the content of a list item can contain block-level elements, you can do the following:
+
+    *   First item
+
+        A second paragraph
+
+        * nested list
+
+        > blockquote
+
+    *   Second item
+
+However, there is a problem when you want to have a code block immediately after a list item. You
+can use an EOB marker to circumvent this problem:
+
+    *   This is a list item.
+
+        The second para of the list item.
+    ^
+        A code block following the list item.
+
+You can have any block-level element as first element in a list item. However, as described above,
+the leading tabs or spaces of the line with the list item marker are stripped away. This leads to a
+problem when you want to have a code block as first element. The solution to this problem is the
+following construct:
+
+    * 
+            This is a code block (indentation needs to be 4(1)+4(1)
+            spaces (tabs)).
+{: .show-whitespaces .ws-lr}
+
+Note that the list marker needs to be followed with at least one space or tab! Otherwise the line is
+not recognized as the start of a list item but interpreted as a paragraph containing the list
+marker.
+
+If you want to have one list directly after another one (both with the same list type, i.e. ordered
+or unordered), you need to use an EOB marker to separate the two:
+
+    * List one
+    ^
+    * List two
+
+Since paragraphs support [line wrapping](#line-wrapping), it would usually not be possible to create
+compact nested list, i.e. a list where the text is not wrapped in paragraphs because there is no
+blank line but a sub list after it:
+
+    *   This is just text.
+        * this is a sub list item
+          * this is a sub sub list item
+    * This is just text,
+        spanning two lines
+      * this is a nested list item.
+
+However, this is an often used syntax and is therefore support by kramdown.
+
+If you want to start a paragraph with something that looks like a list item marker, you need to
+escape it. This is done by escaping the period in an ordered list or the list item marker in an
+unordered list:
+
+    1984\. It was great
+    \- others say that, too!
+
+As mentioned at the beginning, an optional IAL for applying attributes to a list item can be used
+after the list item marker:
+
+    * {:.cls} This item has the class "cls".
+      Here continues the above paragraph.
+
+    * This is a normal list item.
+
+
+### Definition Lists
+
+> This syntax feature is not part of the original Markdown syntax. The idea and syntax comes from
+> the [PHP Markdown Extra] package.
+{: .markdown-difference}
+
+Definition lists allow you to assign one or more definitions to one or more terms.
+
+A definition list is started when a normal paragraph is followed by a line with a definition marker
+(a colon which may be optionally indented up to three spaces), then at least one tab or one space,
+optionally followed by an [IAL](#inline-attribute-lists) that should be applied to the list item and
+then the first part of the definition. The line with the definition marker may optionally be
+separated from the preceding paragraph by a blank line. The leading tabs or spaces are stripped away
+from this first line of the definition to allow for a nice alignment with the following definition
+content. Each line of the preceding paragraph is taken to be a term and the lines separately parsed
+as span-level elements.
+
+The following is a simple definition list:
+
+    kramdown
+    : A Markdown-superset converter
+
+    Maruku
+    :     Another Markdown-superset converter
+
+The column number of the first non-space character which appears after a definition marker on the
+same line specifies the indentation that has to be used for the following lines of the definition.
+If there is no such character, the indentation that needs to be used is four spaces or one tab.
+Indented lines may be followed by lines containing text with any amount of indentation due to [line
+wrapping](#line-wrapping). Note, however, that in addition to the rules outlined in the section
+about line wrapping, a list item also ends when a line with another definition marker is encountered.
+
+The indentation is stripped from the definition and it (note that the definition naturally also
+contains the content of the line with the definition marker) is processed as text containing block
+level elements. If there is more than one definition, all other definition markers for the term may
+be indented up to three spaces or the number of spaces used for the indentation of the last
+definition minus one, whichever number is smaller. For example:
+
+    definition term 1
+    definition term 2
+    : This is the first line. Since the first non-space characters appears in
+    column 3, all other lines have to be indented 2 spaces (or lazy syntax may
+      be used after an indented line). This tells kramdown that the lines
+      belong to the definition.
+    :       This is the another definition for the same term. It uses a
+            different number of spaces for indentation which is okay but
+            should generally be avoided.
+       : The definition marker is indented 3 spaces which is allowed but
+         should also be avoided.
+
+So, while the above is possible and creates a definition list with two terms and three definitions
+for them, it is not advised to use different (definition marker and definition) indents in the same
+definition list as well as lazy indentation!
+
+The definition for a term is made up of text and/or block-level elements. If a definition is *not*
+preceded by a blank line, the first part of the definition will just be text if it would be a
+paragraph otherwise:
+
+    definition term
+    : This definition will just be text because it would normally be a
+      paragraph and the there is no preceding blank line.
+
+      > although the definition contains other block-level elements
+
+    : This definition *will* be a paragraph since it is preceded by a
+      blank line.
+
+The rules about having any block-level element as first element in a list item also apply to a
+definition.
+
+
+## Tables
+
+> This syntax feature is not part of the original Markdown syntax. The syntax is based on the one
+> from the [PHP Markdown Extra] package.
+{: .markdown-difference}
+
+Sometimes one wants to include simple tabular data in a kramdown document for which using a
+full-blown HTML table is just too much. kramdown supports this with a simple syntax for ASCII
+tables.
+
+Tables can be created with or without a leading pipe character: If the first line of a table
+contains a pipe character at the start of the line (optionally indented up to three spaces), then
+all leading pipe characters (i.e. pipe characters that are only preceded by whitespace) are ignored
+on all table lines. Otherwise they are not ignored and count when dividing a table line into table
+cells.
+
+There are four different line types that can be used in a table:
+
+* *Table rows* define the content of a table.
+
+  A table row is any line that contains at least one pipe character and is not identified as any
+  other type of table line! The table row is divided into individual table cells by pipe characters.
+  An optional trailing pipe character is ignored. Note that literal pipe characters need to be
+  escaped *except* if they occur in code spans or HTML `<code>` elements!
+
+  Header rows, footer rows and normal rows are all done using these table rows. Table cells can only
+  contain a single line of text, no multi-line text is supported. The text of a table cell is parsed
+  as span-level elements.
+
+  Here are some example table rows:
+
+      | First cell|Second cell|Third cell
+      | First | Second | Third |
+
+      First | Second | | Fourth |
+
+* *Separator lines* are used to split the table body into multiple body parts.
+
+  A separator line is any line that contains only pipes, dashes, pluses, colons and spaces and which
+  contains at least one dash and one pipe character. The pipe and plus characters can be used to
+  visually separate columns although this is not needed. Multiple separator lines after another are
+  treated as one separator line.
+
+  Here are some example separator lines:
+
+      |----+----|
+      +----|----+

+
+* The first separator line after at least one table row is treated specially, namely as *header
+  separator line*. It is used to demarcate header rows from normal table rows and/or to set column
+  alignments. All table rows above the header separator line are considered to be header rows.
+
+  The header separator line can be specially formatted to contain column alignment definitions: An
+  alignment definition consists of an optional space followed by an optional colon, one or more
+  dashes, an optional colon and another optional space. The colons of an alignment definition are
+  used to set the alignment of a column: if there are no colons, the column uses the default
+  alignment, if there is a colon only before the dashes, the column is left aligned, if there are
+  colons before and after the dashes, the column is center aligned and if there is only a colon
+  after the dashes, the column is right aligned. Each alignment definition sets the alignment for
+  one column, the first alignment definition for the first column, the second alignment definition
+  for the second column and so on.
+
+  Here are some example header separator lines with alignment definitions:
+
+      |---+---+---|
+      + :-: |:------| ---:|
+      | :-: :- -: -
+      :-: | :-
+
+* A *footer separator line* is used to demarcate footer rows from normal table rows. All table rows
+  below the footer separator line are considered to be footer rows.
+
+  A footer separator line is like a normal separator line except that dashes are replaced by equal
+  signs. A footer separator line may only appear once in a table. If multiple footer separator lines
+  are used in one table, only the last is treated as footer separator line, all others are treated
+  as normal separator lines. Normal separator lines that are used after the footer separator line
+  are ignored.
+
+  Here are some example footer separator lines:
+
+      |====+====|
+      +====|====+
+      |=========|
+      |=
+
+Trailing spaces or tabs are ignored in all cases. To simplify table creation and maintenance,
+header, footer and normal separator lines need not specify the same number of columns as table rows;
+even `|-` and `|=` are a valid separators.
+
+Given the above components, a table is specified by
+
+* an optional separator line,
+* optionally followed by zero, one or more table rows followed by a header separator line,
+* one or more table rows, optionally interspersed with separator lines,
+* optionally followed by a footer separator line and zero, one or more table rows and
+* an optional trailing separator line.
+
+Also note
+
+* that the first line of a table must not have more than three spaces of indentation before the
+  first non-space character,
+* that each line of a table needs to have at least one not escaped pipe character so that kramdown
+  recognizes it as a line belonging to the table and
+* that tables have to start and end on [block boundaries](#block-boundaries)!
+
+> The table syntax differs from the one used in [PHP Markdown Extra] as follows:
+>
+> * kramdown tables do not need to have a table header.
+> * kramdown tables can be structured using separator lines.
+> * kramdown tables can contain a table footer.
+> * kramdown tables need to be separated from other block-level elements.
+{: .markdown-difference}
+
+Here is an example for a kramdown table with a table header row, two table bodies and a table footer
+row:

+    | First body part | Second cell | Third cell | fourth cell

+## Horizontal Rules
+
+A horizontal rule for visually separating content is created by using three or more asterisks,
+dashes or underscores (these may not be mixed on a line), optionally separated by spaces or tabs, on
+an otherwise blank line. The first asterisk, dash or underscore may optionally be indented up to
+three spaces. The following examples show different possibilities to create a horizontal rule:

+## Math Blocks
+
+> This syntax feature is not part of the original Markdown syntax. The idea comes from the [Maruku]
+> and [Pandoc] packages.
+{: .markdown-difference}
+
+kramdown has built-in support for block and span-level mathematics written in LaTeX.
+
+A math block needs to start and end on [block boundaries](#block-boundaries). It is started using
+two dollar signs, optionally indented up to three spaces. The math block continues until the next
+two dollar signs (which may be on the same line or on one of the next lines) that appear at the end
+of a line, i.e. they may only be followed by whitespace characters. The content of a math block has
+to be valid LaTeX math. It is always wrapped inside a `\begin{displaymath}...\end{displaymath}`
+enviroment except if it begins with a `\begin` statement.
+
+The following kramdown fragment
+
+    $$
+    \begin{align*}
+      & \phi(x,y) = \phi \left(\sum_{i=1}^n x_ie_i, \sum_{j=1}^n y_je_j \right)
+      = \sum_{i=1}^n \sum_{j=1}^n x_i y_j \phi(e_i, e_j) = \\
+      & (x_1, \ldots, x_n) \left( \begin{array}{ccc}
+          \phi(e_1, e_1) & \cdots & \phi(e_1, e_n) \\
+          \vdots & \ddots & \vdots \\
+          \phi(e_n, e_1) & \cdots & \phi(e_n, e_n)
+        \end{array} \right)
+      \left( \begin{array}{c}
+          y_1 \\
+          \vdots \\
+          y_n
+        \end{array} \right)
+    \end{align*}
+    $$
+
+renders (using Javascript library [MathJax](http://www.mathjax.org/)) as
+
+$$
+\begin{align*}
+  & \phi(x,y) = \phi \left(\sum_{i=1}^n x_ie_i, \sum_{j=1}^n y_je_j \right)
+  = \sum_{i=1}^n \sum_{j=1}^n x_i y_j \phi(e_i, e_j) = \\
+  & (x_1, \ldots, x_n) \left( \begin{array}{ccc}
+      \phi(e_1, e_1) & \cdots & \phi(e_1, e_n) \\
+      \vdots & \ddots & \vdots \\
+      \phi(e_n, e_1) & \cdots & \phi(e_n, e_n)
+    \end{array} \right)
+  \left( \begin{array}{c}
+      y_1 \\
+      \vdots \\
+      y_n
+    \end{array} \right)
+\end{align*}
+$$
+
+Using inline math is also easy: just surround your math content with two dollar signs, like with a
+math block. If you don't want to start an inline math statement, just escape the dollar signs and
+they will be treated as simple dollar signs.
+
+> **Note** that LaTeX code that uses the pipe symbol `|` in inline math statements may lead to a
+> line being recognized as a table line. This problem can be avoided by using the `\vert` command
+> instead of `|`!
+{:.information}
+
+If you have a paragraph that looks like a math block but should actually be a paragraph with just an
+inline math statement, you need to escape the first dollar sign:
+
+    The following is a math block:
+
+    $$ 5 + 5 $$
+
+    But next comes a paragraph with an inline math statement:
+
+    \$$ 5 + 5 $$
+
+If you don't even won't the inline math statement, escape the first two dollar signs:
+
+    \$\$ 5 + 5 $$
+
+## HTML Blocks
+
+> The original Markdown syntax specifies that an HTML block must start at the left margin, i.e. no
+> indentation is allowed. Also, the HTML block has to be surrounded by blank lines. Both
+> restrictions are lifted for kramdown documents. Additionally, the original syntax does not allow
+> you to use Markdown syntax in HTML blocks which is allowed with kramdown.
+{: .markdown-difference}
+
+An HTML block is potentially started if a line is encountered that begins with a non-span-level HTML
+tag or a general XML tag (opening or closing) which may be indented up to three spaces.
+
+The following HTML tags count as span-level HTML tags and *won't* start an HTML block if found at
+the beginning of an HTML block line:
+
+    a abbr acronym b big bdo br button cite code del dfn em i img input
+    ins kbd label option q rb rbc rp rt rtc ruby samp select small span
+    strong sub sup textarea tt var
+
+Further parsing of a found start tag depends on the tag and in which of three possible ways its
+content is parsed:
+
+* Parse as raw HTML block: If the HTML/XML tag content should be handled as raw HTML, then only
+  HTML/XML tags are parsed from this point onwards and text is handled as raw, unparsed text until
+  the matching end tag is found or until the end of the document. Each found tag will be parsed as
+  raw HTML again. However, if a tag has a `markdown` attribute, this attribute controls parsing of
+  this one tag (see below).
+
+  Note that the parser basically supports only correct XHTML! However, there are some exceptions.
+  For example, attributes without values (i.e. boolean attributes) are also supported and elements
+  without content like `<hr />` can be written as `<hr>`. If an invalid closing tag is found, it is
+  ignored.
+
+* Parse as block-level elements: If the HTML/XML tag content should be parsed as text containing
+  block-level elements, the remaining text on the line will be parsed by the block-level parser as
+  if it appears on a separate line (**Caution**: This also means that if the line consists of the
+  start tag, text and the end tag, the end tag will not be found!). All following lines are parsed
+  as block-level elements until an HTML block line with the matching end tag is found or until the
+  end of the document.
+
+* Parse as span-level elements: If the HTML/XML tag content should be parsed as text containing span
+  level elements, then all text until the *next* matching end tag or until the end of the document
+  will be the content of the tag and will later be parsed by the span-level parser. This also means
+  that if the matching end tag is inside what appears to be a code span, it is still used!
+
+If there is text after an end tag, it will be parsed as if it appears on a separate line except when
+inside a raw HTML block.
+
+Also, if an invalid closing tag is found, it is ignored.
+
+Note that all HTML tag and attribute names are converted to lowercase!
+
+By default, kramdown parses all block HTML tags and all XML tags as raw HTML blocks. However, this
+can be configured with the `parse_block_html`. If this is set to `true`, then syntax parsing in HTML
+blocks is globally enabled. It is also possible to enable/disable syntax parsing on a tag per tag
+basis using the `markdown` attribute:
+
+* If an HTML tag has an attribute `markdown="0"`, then the tag is parsed as raw HTML block.
+
+* If an HTML tag has an attribute `markdown="1"`, then the default mechanism for parsing syntax in
+  this tag is used.
+
+* If an HTML tag has an attribute `markdown="block"`, then the content of the tag is parsed as block
+  level elements.
+
+* If an HTML tag has an attribute `markdown="span"`, then the content of the tag is parsed as span
+  level elements.
+
+The following list shows which HTML tags are parsed in which mode by default when `markdown="1"` is
+applied or `parse_block_html` is `true`:
+
+Parse as raw HTML
+: 
+        script style math option textarea pre code kbd samp var
+
+    Also, all general XML tags are parsed as raw HTML blocks.
+
+Parse as block-level elements
+: 
+        applet button blockquote body colgroup dd div dl fieldset form iframe li
+        map noscript object ol table tbody thead tfoot tr td ul
+
+Parse as span-level elements
+: 
+        a abbr acronym address b bdo big cite caption code del dfn dt em
+        h1 h2 h3 h4 h5 h6 i ins kbd label legend optgroup p pre q rb rbc
+        rp rt rtc ruby samp select small span strong sub sup th tt var
+
+> Remember that all span-level HTML tags like `a` or `b` do not start a HTML block! However, the
+> above lists also include span-level HTML tags in the case the `markdown` attribute is used on a
+> tag inside a raw HTML block.
+
+Here is a simple example input and its HTML output with `parse_block_html` set to `false`:
+
+    This is a para.
+    <div>
+    Something in here.
+    </div>
+    Other para.
+^
+    <p>This is a para.</p>
+    <div>
+    Something in here.
+    </div>
+    <p>Other para.</p>
+
+As one can see the content of the `div` tag will be parsed as raw HTML block and left alone.
+However, if the `markdown="1"` attribute was used on the `div` tag, the content would be parsed as
+block-level elements and therefore converted to a paragraph.
+
+You can also use several HTML tags at once:
+
+    <div id="content"><div id="layers"><div id="layer1">
+    This is some text in the `layer1` div.
+    </div>
+    This is some text in the `layers` div.
+    </div></div>
+    This is a para outside the HTML block.
+
+However, remember that if the content of a tag is parsed as block-level elements, the content that
+appears after a start/end tag but on the same line, is processed as if it appears on a new line:
+
+    <div markdown="1">This is the first part of a para,
+    which is continued here.
+    </div>
+
+    <p markdown="1">This works without problems because it is parsed as
+    span-level elements</p>
+
+    <div markdown="1">The end tag is not found because
+    this line is parsed as a paragraph</div>
+
+Since setting `parse_block_html` to `true` can lead to some not wanted behaviour, it is generally
+better to selectively enable or disable block/span-level elements parsing by using the `markdown`
+attribute!
+
+Unclosed block-level HTML tags are correctly closed at the end of the document to ensure correct
+nesting and invalidly used end tags are removed from the output:
+
+    This is a para.
+    <div markdown="1">
+    Another para.
+    </p>
+^
+    <p>This is a para.</p>
+    <div>
+      <p>Another para.</p>
+    </div>
+
+The parsing of processing instructions and XML comments is also supported. The content of both, PIs
+and XML comments, may span multiple lines. The start of a PI/XML comment may only appear at the
+beginning of a line, optionally indented up to three spaces. If there is text after the end of a PI
+or XML comment, it will be parsed as if it appears on a separate line. kramdown syntax in PIs/XML
+comments is not processed:
+
+    This is a para.
+    <!-- a *comment* -->
+    <? a processing `instruction`
+       spanning multiple lines
+    ?> First part of para,
+    continues here.
+
+
+
+# Text Markup
+
+These elements are all span-level elements and used inside block-level elements to markup text
+fragments. For example, one can easily create links or apply emphasis to certain text parts.
+
+Note that empty span-level elements are not converted to empty HTML tags but are copied as-is to the
+output.
+
+
+
+## Links and Images
+
+Three types of links are supported: automatic links, inline links and reference links.
+
+### Automatic Links
+
+This is the easiest one to create: Just surround a web address or an email address with angle
+brackets and the address will be turned into a proper link. The address will be used as link target
+and as link text. For example:
+
+    Information can be found on the <http://example.com> homepage.
+    You can also mail me: <me.example at example.com>
+
+It is not possible to specify a different link text using automatic links -- use the other link
+types for this!
+
+
+### Inline Links
+
+As the wording suggests, inline links provide all information inline in the text flow. Reference
+style links only provide the link text in the text flow and everything else is defined
+elsewhere. This also allows you to reuse link definitions.
+
+An inline style link can be created by surrounding the link text which must contain at least one
+character with square brackets, followed immediately by the link URL (and an optional title in
+single or double quotes preceded by at least one space) in normal parentheses. For example:
+
+    This is [a link](http://rubyforge.org) to a page.
+    A [link](../test "local URI") can also have a title.
+    And [spaces](link with spaces.html)!
+
+Notes:
+
+* The link text is treated like normal span-level text and therefore is parsed and converted.
+  However, if you use square brackets within the link text, you have to either properly nest them or
+  to escape them. It is not possible to create nested links!
+
+* The link URL must not contain single or double quotes and it has to contain properly nested
+  parentheses if no title is specified, or the link URL must be contained in angle brackets
+  (incorrectly nested parentheses are allowed).
+
+* The link title may not contain its delimiters and may not be empty.
+
+### Reference Links
+
+To create a reference style link, you need to surround the link text with square brackets (as with
+inline links), followed by optional spaces/tabs/line breaks and then optionally followed with
+another set of square brackets with the link identifier in them. A link identifier may not contain a
+closing bracket and, when specified in a link definition, newline characters; it is also not case
+sensitive, line breaks and tabs are converted to spaces and multiple spaces are compressed into one.
+For example:
+
+    This is a [reference style link][linkid] to a page. And [this]
+    [linkid] is also a link. As is [this][] and [THIS].
+
+If you don't specify a link identifier (i.e. only use empty square brackets) or completely omit the
+second pair of square brackets, the link text is converted to a valid link identifier by removing
+all invalid characters and inserting spaces for line breaks. If there is a link definition found for
+the link identifier, a link will be created. Otherwise the text is not converted to a link.
+
+### Link Definitions
+
+The link definition can be put anywhere in the document. It does not appear in the output. A link
+definition looks like this:
+
+    [linkid]: http://www.example.com/ "Optional Title"
+
+> Link definitions are, despite being described here, non-content block-level elements.
+{: .information}
+
+The link definition has the following structure:
+
+* The link identifier in square brackets, optionally indented up to three spaces,
+* then a colon and one or more spaces/tabs,
+* then the link URL which must not contain any single or double quotes and which must contain at
+  least one non-space character, or a left angle bracket, the link URL and a right angle bracket,
+* then optionally the title in single or double quotes, separated from the link URL by one or more
+  spaces or on the next line by itself indented any number of spaces/tabs.
+
+> The original Markdown syntax also allowed the title to be specified in parenthesis. This is not
+> allowed for consistency with the inline title.
+{: .markdown-difference}
+
+If you have some text that looks like a link definition but should really be a link and some text,
+you can escape the colon after the link identifier:
+
+    The next paragraph contains a link and some text.
+
+    [Room 100]\: There you should find everything you need!
+
+    [Room 100]: link_to_room_100.html
+
+
+### Images
+
+Images can be specified via a syntax that is similar to the one used by links. The difference is
+that you have to use an exclamation mark before the first square bracket and that the link text of a
+normal link, which may also be the empty string in case of image links, becomes the alternative text
+of the image link. As with normal links, image links can be written inline or reference style. For
+example:
+
+    Here comes a ![smiley](../images/smiley.png)! And here
+    ![too](../images/other.png 'Title text'). Or ![here].
+    With empty alt text ![](see.jpg)
+
+The link definition for images is exactly the same as the link definition for normal links.
+
+
+## Emphasis
+
+kramdown supports two types of emphasis: light and strong emphasis. Text parts that are surrounded
+with single asterisks `*` or underscores `_` are treated as text with light emphasis, text parts
+surrounded with two asterisks or underscores are treated as text with strong emphasis. Surrounded
+means that the starting delimiter must not be followed by a space and that the stopping delimiter
+must not be preceded by a space.
+
+Here is an example for text with light and strong emphasis:
+
+    *some text*
+    _some text_
+    **some text**
+    __some text__
+
+The asterisk form is also allowed within a single word:
+
+    This is un*believe*able! This d_oe_s not work!
+
+Text can be marked up with both light and strong emphasis, possibly using different delimiters.
+However, it is not possible to nest strong within strong or light within light emphasized text:
+
+    This is a ***text with light and strong emphasis***.
+    This **is _emphasized_ as well**.
+    This *does _not_ work*.
+    This **does __not__ work either**.
+
+If one or two asterisks or underscores are surrounded by spaces, they are treated literally. If you
+want to force the literal meaning of an asterisk or an underscore you can backslash-escape it:
+
+    This is a * literal asterisk.
+    These are ** two literal asterisk.
+    As \*are\* these!
+
+
+## Code Spans
+
+This is the span-level equivalent of the [code block](#code-blocks) element. You can markup a text
+part as code span by surrounding it with backticks `` ` ``. For example:
+
+    Use `<html>` tags for this.
+
+Note that all special characters in a code span are treated correctly. For example, when a code span
+is converted to HTML, the characters `<`, `>` and `&` are substituted by their respective HTML
+counterparts.
+
+To include a literal backtick in a code span, you need to use two or more backticks as delimiters.
+You can insert one optional space after the starting and before the ending delimiter (these spaces
+are not used in the output). For example:
+
+    Here is a literal `` ` `` backtick.
+    And here is ``  `some`  `` text (note the two spaces so that one is left
+    in the output!).
+
+A single backtick surrounded by spaces is treated as literal backtick. If you want to force the
+literal meaning of a backtick you can backslash-escape it:
+
+    This is a ` literal backtick.
+    As \`are\` these!
+
+As with [code blocks](#language-of-code-blocks) you can set the language of a code span by using an
+[IAL](#inline-attribute-lists):
+
+    This is a Ruby code fragment `x = Class.new`{:.language-ruby}
+
+
+## HTML Spans
+
+HTML tags cannot only be used on the block-level but also on the span-level. Span-level HTML tags
+can only be used inside one block-level element, it is not possible to use a start tag in one block
+level element and the end tag in another. Note that only correct XHTML is supported! This means that
+you have to use, for example, `<br />` instead of `<br>` (although kramdown tries to fix such errors
+if possible).
+
+By default, kramdown parses kramdown syntax inside span HTML tags. However, this behaviour can be
+configured with the `parse_span_html` option. If this is set to `true`, then syntax parsing in HTML
+spans is enabled, if it is set to `false`, parsing is disabled. It is also possible to
+enable/disable syntax parsing on a tag per tag basis using the `markdown` attribute:
+
+* If an HTML tag has an attribute `markdown="0"`, then no parsing (except parsing of HTML span tags)
+  is done inside that HTML tag.
+
+* If an HTML tag has an attribute `markdown="1"`, then the content of the tag is parsed as span
+  level elements.
+
+* If an HTML tag has an attribute `markdown="block"`, then a warning is issued because HTML spans
+  cannot contain block-level elements and the attribute is ignored.
+
+* If an HTML tag has an attribute `markdown="span"`, then the content of the tag is parsed as span
+  level elements.
+
+The content of a span-level HTML tag is normally parsed as span-level elements. Note, however, that
+some tags like `<script>` are not parsed, i.e. their content is not modified.
+
+Processing instructions and XML comments can also be used (their content is not parsed). However, as
+with HTML tags the start and the end have to appear in the same block-level element.
+
+Span-level PIs and span-level XML comments as well as general span-level HTML and XML tags have to
+be preceded by at least one non whitespace character on the same line so that kramdown correctly
+recognizes them as span-level element and not as block-level element. However, all span HTML tags,
+i.e. `a`, `em`, `b`, ..., (opening or closing) can appear at the start of a line.
+
+Unclosed span-level HTML tags are correctly closed at the end of the span-level text to ensure
+correct nesting and invalidly used end tags or block HTML tags are removed from the output:
+
+    This is </invalid>.

+## Footnotes
+
+> This syntax feature is not part of the original Markdown syntax. The idea and syntax comes from
+> the [PHP Markdown Extra] package.
+{: .markdown-difference}
+
+Footnotes in kramdown are similar to reference style links and link definitions. You need to place
+the footnote marker in the correct position in the text and the actual footnote content can be
+defined anywhere in the document.
+
+More exactly, a footnote marker can be created by placing the footnote name in square brackets.
+The footnote name has to start with a caret (`^`), followed by a word character or a digit and then
+optionally followed by other word characters, digits or dashes. For example:
+
+    This is some text.[^1]. Other text.[^footnote].
+
+Footnote markers with the same name will link to the same footnote definition. The actual naming of
+a footnote does not matter since the numbering of footnotes is controlled via the position of the
+footnote markers in the document (the first found footnote marker will get the number 1, the second 
+new footnote marker the number 2 and so on). If there is a footnote definition found for the
+identifier, a footnote will be created. Otherwise the footnote marker is not converted to a footnote
+link. Also note that all attributes set via a span IAL are ignored for a footnote marker!
+
+A footnote definition is used to define the content of a footnote and has the following structure:
+
+* The footnote name in square brackets, optionally indented up to three spaces,
+* then a colon and one or more optional spaces,
+* then the text of the footnote
+* and optionally more text on the following lines which have to follow the syntax for [standard code
+  blocks](#standard-code-blocks) (the leading four spaces/one tab are naturally stripped from the
+  text)
+
+> Footnote definitions are, despite being described here, non-content block-level elements.
+{: .information}
+
+The whole footnote content is treated like block-level text and can therefore contain any valid
+block-level element (also, any block-level element can be the first element). If you want to have a
+code block as first element, note that all leading spaces/tabs on the first line are stripped away.
+Here are some example footnote definitions:
+
+    [^1]: Some *crazy* footnote definition.
+
+    [^footnote]:
+        > Blockquotes can be in a footnote.
+
+            as well as code blocks
+
+        or, naturally, simple paragraphs.
+
+    [^other-note]:       no code block here (spaces are stripped away)
+
+    [^codeblock-note]:
+            this is now a code block (8 spaces indentation)
+
+It does not matter where you put a footnote definition in a kramdown document; the content of all
+referenced footnote definitions will be placed at the end of the kramdown document. Not referenced
+footnote definitions are ignored. If more than one footnote definitions have the same footnote name,
+all footnote definitions but the last are ignored.
+
+
+## Abbreviations
+
+> This syntax feature is not part of the original Markdown syntax. The idea and syntax comes from
+> the [PHP Markdown Extra] package.
+{: .markdown-difference}
+
+kramdown provides a syntax to assign the full phrase to an abbreviation. When writing the text, you
+don't need to do anything special. However, once you add abbreviation definitions, the
+abbreviations in the text get marked up automatically. Abbreviations can consist of any character
+except a closing bracket.
+
+An abbreviation definition is used to define the full phrase for an abbreviation and has the
+following structure:
+
+* An asterisk and the abbreviation in square brackets, optionally indented up to three
+  spaces,
+* then a colon and the full phrase of the abbreviation on one line (leading and trailing spaces are
+  stripped from the full phrase).
+
+Later abbreviation definition for the same abbreviation override prior ones and it does not matter
+where you put an abbreviation definition in a kramdown document. Empty definitions are also allowed.
+
+Here are some examples:
+
+    This is some text not written in HTML but in another language!
+
+    *[another language]: It's called Markdown
+    *[HTML]: HyperTextMarkupLanguage
+
+> Abbreviation definitions are, despite being described here, non-content block-level elements.
+{: .information}
+
+
+## Typographic Symbols
+
+> The original Markdown syntax does not support these transformations.
+{: .markdown-difference}
+
+kramdown converts the following plain ASCII character into their corresponding typographic symbols:
+
+* `---` will become an em-dash (like this ---)
+* `--` will become an en-dash (like this --)
+* `...` will become an ellipsis (like this ...)
+* `<<` will become a left guillemet (like this <<) -- an optional following space will become a
+  non-breakable space
+* `>>` will become a right guillemet (like this >>) -- an optional leading space will become a
+  non-breakable space
+
+The parser also replaces normal single `'` and double quotes `"` with "fancy quotes". There *may* be
+times when kramdown falsely replace the quotes. If this is the case, just \'escape\" the quotes and
+they won't be replaced with fancy ones.
+
+
+
+# Non-content elements
+
+This section describes the non-content elements that are used in kramdown documents, i.e. elements
+that don't provide content for the document but have other uses such as separating block-level
+elements or attaching attributes to elements.
+
+Three non-content block-level elements are not described here because they fit better where they
+are:
+
+* [link definitions](#link-definitions)
+* [footnote definitions](#footnotes)
+* [abbreviation definition](#abbreviations)
+
+
+## End-Of-Block Marker    {#eob-marker}
+
+> The EOB marker is not part of the standard Markdown syntax.
+{: .markdown-difference}
+
+The End-Of-Block (EOB) marker -- a `^` as first character on an otherwise empty line -- is a block
+level element that can be used to specify the end of a block-level element even if the block-level
+element, after which it is used, would continue otherwise. If there is no block-level element to
+end, the EOB marker is simply ignored.
+
+You won't find an EOB marker in most kramdown documents but sometimes it is necessary to use it to
+achieve the wanted results which would be impossible otherwise. However, it should only be used when
+absolutely necessary!
+
+For example, the following gives you one list with two items:
+
+    * list item one
+
+    * list item two
+
+By using an EOB marker, you can make two lists with one item each:
+
+    * list one
+    ^
+    * list two
+
+
+## Attribute List Definitions
+
+> This syntax feature is not part of the original Markdown syntax. The idea and syntax comes from
+> the [Maruku] package.
+{: .markdown-difference}
+
+This is an implementation of [Maruku]'s feature for adding attributes to block and span-level
+elements (the naming is also taken from Maruku). This block-level element is used to define
+attributes which can be referenced later. The [Block Inline Attribute List](#block-ials) is used to
+attach attributes to a block-level element and the [Span Inline Attribute List](#span-ials) is used
+to attach attributes to a span-level element.
+
+Following are some examples of attribute list definitions (ALDs) and afterwards comes the syntax
+explanation:
+
+    {:ref-name: #myid .my-class}
+    {:other: ref-name #id-of-other title="hallo you"}
+    {:test: key="value \" with quote" and other='quote brace \}'}
+
+An ALD line has the following structure:
+
+* a left brace, optionally preceded by up to three spaces,
+* followed by a colon, the reference name and another colon,
+* followed by attribute definitions (allowed characters are backslash-escaped closing braces or any
+  character except a not escaped closing brace),
+* followed by a closing brace and optional spaces until the end of the line.
+
+The reference name needs to start with a word character or a digit, optionally followed by other
+word characters, digits or dashes.
+
+There are four different types of attribute definitions which have to be separated by one or more
+spaces:
+
+references
+
+: This must be a valid reference name. It is used to reference an other ALD so that the attributes
+  of the other ALD are also included in this one. The reference name is ignored when collecting the
+  attributes if no attribute definition list with this reference name exists. For example, a simple
+  reference looks like `id`.
+
+key-value pairs
+
+: A key-value pair is defined by a key name, which must follow the rules for reference names, then
+  an equal sign and then the value in single or double quotes. If you need to use the value
+  delimiter (a single or a double quote) inside the value, you need to escape it with a backslash.
+  Key-value pairs can be used to specify arbitrary attributes for block or span-level elements. For
+  example, a key-value pair looks like `key1="bef \"quoted\" aft"` or `title='This is a title'`.
+
+ID name
+
+: An ID name is defined by using a hash and then the identifier name which needs to start with an
+  ASCII alphabetic character (A-Z or a-z), optionally followed by other ASCII characters, digits,
+  dashes or colons. This is a short hand for the key-value pair `id="IDNAME"` since this is often
+  used. The ID name specifies the unique ID of a block or span-level element. For example, an ID
+  name looks like `#myid`.
+
+class names
+
+: A class name is defined by using a dot and then the class name. This is (almost, but not quite) a
+  short hand for the key-value pair `class="class-name"`. Almost because it actually means that the
+  class name should be appended to the current value of the `class` attribute. The following ALDs
+  are all equivalent:
+
+      {:id: .cls1 .cls2}
+      {:id: class="cls1" .cls2}
+      {:id: class="something" class="cls1" .cls2}
+      {:id: class="cls1 cls2"}
+
+As can be seen from the example of the class names, attributes that are defined earlier are
+overwritten by ones with the same name defined later.
+
+> Also, everything in the attribute definitions part that does not match one of the above four types
+> is ignored.
+{:.information}
+
+If there is more than one ALD with the same reference name, the attribute definitions of all the
+ALDs are processed like they are defined in one ALD.
+
+
+## Inline Attribute Lists
+
+These elements are used to attach attributes to another element.
+
+### Block Inline Attribute Lists   {#block-ials}
+
+> This syntax feature is not part of the original Markdown syntax. The idea and syntax comes from
+> the [Maruku] package.
+{: .markdown-difference}
+
+This block-level element is used to attach attributes to a block-level element. A block inline
+attribute list (block IAL) has the same structure as an [ALD](#attribute-list-definitions) except
+that the colon/reference name/colon part is replaced by a colon. A block IAL (or two or more block
+IALs) has to be put directly before or after the block-level element to which the attributes should
+be attached. If a block IAL is directly after *and* before a block-level element, it is applied to
+preceding element. The block IAL is ignored in all other cases, for example, when the block IAL is
+surrounded by blank lines.
+
+Key-value pairs of an IAL take precedence over equally named key-value pairs in referenced ALDs.
+
+Here are some examples for block IALs:
+
+    A simple paragraph with an ID attribute.
+    {: #para-one}
+
+    > A blockquote with a title
+    {:title="The blockquote title"}
+    {: #myid}
+
+    {:.ruby}
+        Some code here
+
+### Span Inline Attribute Lists      {#span-ials}
+
+> This syntax feature is not part of the original Markdown syntax. The idea and syntax comes from
+> the [Maruku] package.
+{: .markdown-difference}
+
+This is a version of the [block inline attribute list](#block-ials) for span-level elements. It has
+the same structure as the block IAL except that leading and trailing spaces are not allowed. A span
+IAL (or two or more span IALs) has to be put directly after the span-level element to which it
+should be applied, no additional character is allowed between, otherwise it is ignored and only
+removed from the output.
+
+Here are some examples for span IALs:
+
+    This *is*{:.underline} some `code`{:#id}{:.class}.
+    A [link](test.html){:rel='something'} and some **tools**{:.tools}.
+
+The special span IAL `{::}` contains no attributes but doesn't generate a warning either. It can be
+used to separate consecutive elements that would be falsely parsed if not separated. Here is an use
+case:
+
+    This *is italic*{::}*marked*{:.special} text
+
+
+## Extensions
+
+> This syntax feature is not part of the original Markdown syntax.
+{: .markdown-difference}
+
+Extensions provide additional functionality but use the same syntax for it. They are available as
+block as well as span-level elements.
+
+The syntax for an extension is very similar to the syntax of [ALDs](#attribute-list-definitions).
+Here are some examples of how to specify extensions and afterwards is the syntax definition:
+
+    {::comment}
+    This text is completely ignored by kramdown - a comment in the text.
+    {:/comment}
+
+    Do you see {::comment}this text{:/comment}?
+    {::comment}some other comment{:/}
+
+    {::options key="val" /}
+
+An extension can be specified with or without a body. Therefore there exist a start and an end tag
+for extensions. The start tag has the following structure:
+
+* a left brace,
+* followed by two colons and the extension name,
+* optionally followed by a space and attribute definitions (allowed characters are backslash-escaped
+  closing braces or any character except a not escaped closing brace -- same as with ALDs),
+* followed by a slash and a right brace (in case the extension has no body) or only a right
+  brace (in case the extension has a body).
+
+The stop tag has the following structure:
+
+* a left brace,
+* followed by a colon and a slash,
+* optionally followed by the extension name,
+* followed by a right brace.
+
+A stop tag is only needed if the extension has a body!
+
+The above syntax can be used as is for span-level extensions. The starting and ending lines for block-level
+extensions are defined as:
+
+* The starting line consists of the extension start tag, optionally preceded by up to three spaces,
+  and followed by optional spaces until the end of the line.
+* The ending line consists of the extension stop tag, optionally preceded by up to three spaces,
+  and followed by optional spaces until the end of the line.
+
+If no end tag can be found for an extension start tag, the start tag is treated as if it has no
+body. If an invalid extension stop tag is found, it is ignored. If an invalid extension name is
+specified the extension (and the eventually specified body) are ignored.
+
+The following extensions can be used with kramdown:
+
+`comment`
+
+: Treat the body text as a comment which does not show in the output.
+
+`nomarkdown`
+
+: Don't process the body with kramdown but output it as-is. The attribute `type` specifies which
+  converters should output the body: if the attribute is missing, all converters should output it.
+  Otherwise the attribute value has to be a space separated list of converter names and these
+  converters should output the body.
+
+`options`
+
+: Should be used without a body since the body is ignored. Is used for setting the global options
+  for the kramdown processor (for example, to disable automatic header ID generation). Note that
+  options that are used by the parser are immediately effective whereas all other options are not!
+  This means, for example, that it is not possible to set converter options only for some part of a
+  kramdown document.

+# Tests and Benchmark
+
+## Tests
+
+There exist several test suites for testing the correctness of a Markdown implementation. The
+original [Markdown Test Suite] is the standard which one needs to test against. The [PHP Markdown
+suite][MDTest] contains the original test suite and several more tests (some specifically geared
+towards the extension of the PHP Markdown Extra package). I have used the latter test tool to
+roughly verify that kramdown is able to parse standard Markdown. However, since the syntax used by
+kramdown varies slightly from standard Markdown most of the tests fail - which is fine. When looking
+at the differences one can see that the failures result from these differences.
+
+Besides using the above mentioned test suite kramdown comes with its own set of tests which is used
+to verify that the implementation matches the kramdown specification.
+
+If you believe you have found a bug in the implementation, please follow these steps:
+
+* Check the [syntax page](syntax.html) and see if the behaviour is not intended.
+
+* If the behaviour is not intended and it seems that kramdown should parse some text in another
+  fashion, please open a [bug report] and attach two files: one with the text and one with the HTML
+  conversion you think is correct.
+
+[bug report]: http://github.com/gettalong/kramdown/issues

+
+## Benchmark
+
+kramdown comes with a small benchmark to test how fast it is in regard to four other Ruby Markdown
+implementations: Maruku, BlueFeather, BlueCloth, RDiscount and Redcarpet. The first two are written
+using only Ruby, the latter three are written in C and need to be compiled.
+
+As one can see below, kramdown is currently (January 2014) ~2.5x faster than Maruku, ~4-6x faster
+than BlueFeather but ~30x slower than BlueCloth and RDiscount and ~150x slower than Redcarpet:

+  module Converter
+
+    # == \Base class for converters
+    #
+    # This class serves as base class for all converters. It provides methods that can/should be
+    # used by all converters (like #generate_id) as well as common functionality that is
+    # automatically applied to the result (for example, embedding the output into a template).
+    #
+    # A converter object is used as a throw-away object, i.e. it is only used for storing the needed
+    # state information during conversion. Therefore one can't instantiate a converter object
+    # directly but only use the Base::convert method.
+    #
+    # == Implementing a converter
+    #
+    # Implementing a new converter is rather easy: just derive a new class from this class and put
+    # it in the Kramdown::Converter module (the latter is only needed if auto-detection should work
+    # properly). Then you need to implement the #convert method which has to contain the conversion
+    # code for converting an element and has to return the conversion result.
+    #
+    # The actual transformation of the document tree can be done in any way. However, writing one
+    # method per element type is a straight forward way to do it - this is how the Html and Latex
+    # converters do the transformation.
+    #
+    # Have a look at the Base::convert method for additional information!
+    class Base
+
+      # Can be used by a converter for storing arbitrary information during the conversion process.
+      attr_reader :data
+
+      # The hash with the conversion options.
+      attr_reader :options
+
+      # The root element that is converted.
+      attr_reader :root
+
+      # The warnings array.
+      attr_reader :warnings
+
+      # Initialize the converter with the given +root+ element and +options+ hash.
+      def initialize(root, options)
+        @options = options
+        @root = root
+        @data = {}
+        @warnings = []
+      end
+      private_class_method(:new, :allocate)
+
+      # Returns whether the template should be applied before the conversion of the tree.
+      #
+      # Defaults to false.
+      def apply_template_before?
+        false
+      end
+
+      # Returns whether the template should be applied ater the conversion of the tree.
+      #
+      # Defaults to true.
+      def apply_template_after?
+        true
+      end
+
+      # Convert the element tree +tree+ and return the resulting conversion object (normally a
+      # string) and an array with warning messages. The parameter +options+ specifies the conversion
+      # options that should be used.
+      #
+      # Initializes a new instance of the calling class and then calls the #convert method with
+      # +tree+ as parameter.
+      #
+      # If the +template+ option is specified and non-empty, the template is evaluate with ERB
+      # before and/or after the tree conversion depending on the result of #apply_template_before?
+      # and #apply_template_after?. If the template is evaluated before, an empty string is used for
+      # the body; if evaluated after, the result is used as body. See ::apply_template.
+      #
+      # The template resolution is done in the following way (for the converter ConverterName):
+      #
+      # 1. Look in the current working directory for the template.
+      #
+      # 2. Append +.converter_name+ (e.g. +.html+) to the template name and look for the resulting
+      #    file in the current working directory (the form +.convertername+ is deprecated).
+      #
+      # 3. Append +.converter_name+ to the template name and look for it in the kramdown data
+      #    directory (the form +.convertername+ is deprecated).
+      #
+      # 4. Check if the template name starts with 'string://' and if so, strip this prefix away and

+    #          key :parent is always set and contains the parent element as value.

+    # directly.
+    #
+    # There can be the following two methods for each element type: render_TYPE(el, opts) and
+    # TYPE_options(el, opts) where +el+ is a kramdown element and +opts+ an hash with rendering
+    # options.
+    #
+    # The render_TYPE(el, opts) is used for rendering the specific element. If the element is a span
+    # element, it should return a hash or an array of hashes that can be used by the #formatted_text
+    # method of Prawn::Document. This method can then be used in block elements to actually render
+    # the span elements.
+    #
+    # The rendering options are passed from the parent to its child elements. This allows one to
+    # define general options at the top of the tree (the root element) that can later be changed or
+    # amended.
+    #
+    #
+    # Currently supports the conversion of all elements except those of the following types:
+    #
+    #   :html_element, :img, :footnote

+# kramdown is yet-another-markdown-parser but fast, pure Ruby, using a strict syntax definition and
+# supporting several common extensions.
+#
+# The kramdown library is mainly written to support the kramdown-to-HTML conversion chain. However,
+# due to its flexibility it supports other input and output formats as well. Here is a list of the
+# supported formats:
+#
+# * input formats: kramdown (a Markdown superset), Markdown, HTML
+# * output formats: HTML, kramdown, LaTeX (and therefore PDF)
+#
+# All the documentation on the available input and output formats is available at
+# http://kramdown.gettalong.org.
+#
+# == Usage
+#
+# kramdown has a basic *Cloth API, so using kramdown is as easy as
+#
+#     require 'kramdown'
+#
+#     Kramdown::Document.new(text).to_html
+#
+# For detailed information have a look at the Kramdown::Document class.

+
+    define(:template, String, '', <<EOF)
+The name of an ERB template file that should be used to wrap the output
+or the ERB template itself.
+
+This is used to wrap the output in an environment so that the output can
+be used as a stand-alone document. For example, an HTML template would
+provide the needed header and body tags so that the whole output is a
+valid HTML file. If no template is specified, the output will be just
+the converted text.
+
+When resolving the template file, the given template name is used first.
+If such a file is not found, the converter extension (the same as the
+converter name) is appended. If the file still cannot be found, the
+templates name is interpreted as a template name that is provided by
+kramdown (without the converter extension). If the file is still not
+found, the template name is checked if it starts with 'string://' and if
+it does, this prefix is removed and the rest is used as template
+content.
+
+kramdown provides a default template named 'document' for each converter.
+
+Default: ''
+Used by: all converters
+EOF
+
+    define(:auto_ids, Boolean, true, <<EOF)
+Use automatic header ID generation
+
+If this option is `true`, ID values for all headers are automatically
+generated if no ID is explicitly specified.
+
+Default: true
+Used by: HTML/Latex converter
+EOF
+
+    define(:auto_id_stripping, Boolean, false, <<EOF)
+Strip all formatting from header text for automatic ID generation
+
+If this option is `true`, only the text elements of a header are used
+for generating the ID later (in contrast to just using the raw header
+text line).
+
+This option will be removed in version 2.0 because this will be the
+default then.
+
+Default: false
+Used by: kramdown parser
+EOF
+
+    define(:auto_id_prefix, String, '', <<EOF)
+Prefix used for automatically generated header IDs
+
+This option can be used to set a prefix for the automatically generated
+header IDs so that there is no conflict when rendering multiple kramdown
+documents into one output file separately. The prefix should only
+contain characters that are valid in an ID!
+
+Default: ''
+Used by: HTML/Latex converter
+EOF
+
+    define(:transliterated_header_ids, Boolean, false, <<EOF)
+Transliterate the header text before generating the ID
+
+Only ASCII characters are used in headers IDs. This is not good for
+languages with many non-ASCII characters. By enabling this option
+the header text is transliterated to ASCII as good as possible so that
+the resulting header ID is more useful.
+
+The stringex library needs to be installed for this feature to work!
+
+Default: false
+Used by: HTML/Latex converter
+EOF
+
+    define(:parse_block_html, Boolean, false, <<EOF)
+Process kramdown syntax in block HTML tags
+
+If this option is `true`, the kramdown parser processes the content of
+block HTML tags as text containing block-level elements. Since this is
+not wanted normally, the default is `false`. It is normally better to
+selectively enable kramdown processing via the markdown attribute.
+
+Default: false
+Used by: kramdown parser
+EOF
+
+    define(:parse_span_html, Boolean, true, <<EOF)
+Process kramdown syntax in span HTML tags
+
+If this option is `true`, the kramdown parser processes the content of
+span HTML tags as text containing span-level elements.
+
+Default: true
+Used by: kramdown parser
+EOF
+
+    define(:html_to_native, Boolean, false, <<EOF)
+Convert HTML elements to native elements
+
+If this option is `true`, the parser converts HTML elements to native
+elements. For example, when parsing `<em>hallo</em>` the emphasis tag
+would normally be converted to an `:html` element with tag type `:em`.
+If `html_to_native` is `true`, then the emphasis would be converted to a
+native `:em` element.
+
+This is useful for converters that cannot deal with HTML elements.

+    # == \Base class for parsers
+    #
+    # This class serves as base class for parsers. It provides common methods that can/should be
+    # used by all parsers, especially by those using StringScanner(Kramdown) for parsing.
+    #
+    # A parser object is used as a throw-away object, i.e. it is only used for storing the needed
+    # state information during parsing. Therefore one can't instantiate a parser object directly but
+    # only use the Base::parse method.
+    #
+    # == Implementing a parser
+    #
+    # Implementing a new parser is rather easy: just derive a new class from this class and put it
+    # in the Kramdown::Parser module -- the latter is needed so that the auto-detection of the new
+    # parser works correctly. Then you need to implement the +#parse+ method which has to contain
+    # the parsing code.
+    #
+    # Have a look at the Base::parse, Base::new and Base#parse methods for additional information!

+
+    # Used for parsing a document in kramdown format.

+    # If you want to extend the functionality of the parser, you need to do the following:
+    #
+    # * Create a new subclass
+    # * add the needed parser methods
+    # * modify the @block_parsers and @span_parsers variables and add the names of your parser
+    #   methods
+    #
+    # Here is a small example for an extended parser class that parses ERB style tags as raw text if
+    # they are used as span-level elements (an equivalent block-level parser should probably also be
+    # made to handle the block case):

+.TH "KRAMDOWN" 1 "June 2014"
+.SH NAME
+kramdown \- a fast, pure-Ruby Markdown-superset converter
+.SH SYNOPSIS
+.B kramdown
+[\fIoptions\fR]
+[\fIFILE\fR ...]
+.SH DESCRIPTION
+kramdown is primarily used for parsing a superset of Markdown and converting it to different output
+formats. It supports standard Markdown (with some minor modifications) and various extensions like
+tables and definition lists. Due to its modular architecture it also allows other input formats than
+Markdown, for example, HTML or Github Flavored Markdown.
+
+If \fIFILE\fR is not specified, kramdown reads from the standard input. The result is written to the
+standard output.
+
+There are two sets of options that kramdown accepts: The first one includes the options that are
+used directly by the kramdown binary. The second set of options controls how kramdown parses and
+converts its input.
+.SH OPTIONS
+.TP
+.B \-i, \-\-input ARG
+Specify the input format. Available input formats: kramdown (this is the default), markdown, GFM or html.
+.TP
+.B \-o, \-\-output ARG
+Specify one or more output formats separated by commas: html (default), kramdown, latex, pdf or
+remove_html_tags.
+.TP
+.B \-v, \-\-version
+Show the version of kramdown.
+.TP
+.B \-h, \-\-help
+Show the help.
+
+.SH KRAMDOWN OPTIONS
+
+.TP
+.B \-\-template ARG
+
+The name of an ERB template file that should be used to wrap the output
+or the ERB template itself.
+
+This is used to wrap the output in an environment so that the output can
+be used as a stand-alone document. For example, an HTML template would
+provide the needed header and body tags so that the whole output is a
+valid HTML file. If no template is specified, the output will be just
+the converted text.
+
+When resolving the template file, the given template name is used first.
+If such a file is not found, the converter extension (the same as the
+converter name) is appended. If the file still cannot be found, the
+templates name is interpreted as a template name that is provided by
+kramdown (without the converter extension). If the file is still not
+found, the template name is checked if it starts with 'string://' and if
+it does, this prefix is removed and the rest is used as template
+content.
+
+kramdown provides a default template named 'document' for each converter.
+
+Default: ''
+Used by: all converters
+
+
+.TP
+.B \-\-[no\-]auto-ids
+
+Use automatic header ID generation
+
+If this option is `true`, ID values for all headers are automatically
+generated if no ID is explicitly specified.
+
+Default: true
+Used by: HTML/Latex converter
+
+
+.TP
+.B \-\-[no\-]auto-id-stripping
+
+Strip all formatting from header text for automatic ID generation
+
+If this option is `true`, only the text elements of a header are used
+for generating the ID later (in contrast to just using the raw header
+text line).
+
+This option will be removed in version 2.0 because this will be the
+default then.
+
+Default: false
+Used by: kramdown parser
+
+
+.TP
+.B \-\-auto-id-prefix ARG
+
+Prefix used for automatically generated header IDs
+
+This option can be used to set a prefix for the automatically generated
+header IDs so that there is no conflict when rendering multiple kramdown
+documents into one output file separately. The prefix should only
+contain characters that are valid in an ID!
+
+Default: ''
+Used by: HTML/Latex converter
+
+
+.TP
+.B \-\-[no\-]transliterated-header-ids
+
+Transliterate the header text before generating the ID
+
+Only ASCII characters are used in headers IDs. This is not good for
+languages with many non-ASCII characters. By enabling this option
+the header text is transliterated to ASCII as good as possible so that
+the resulting header ID is more useful.
+
+The stringex library needs to be installed for this feature to work!
+
+Default: false
+Used by: HTML/Latex converter
+
+
+.TP
+.B \-\-[no\-]parse-block-html
+
+Process kramdown syntax in block HTML tags
+
+If this option is `true`, the kramdown parser processes the content of
+block HTML tags as text containing block-level elements. Since this is
+not wanted normally, the default is `false`. It is normally better to
+selectively enable kramdown processing via the markdown attribute.
+
+Default: false
+Used by: kramdown parser
+
+
+.TP
+.B \-\-[no\-]parse-span-html
+
+Process kramdown syntax in span HTML tags
+
+If this option is `true`, the kramdown parser processes the content of
+span HTML tags as text containing span-level elements.
+
+Default: true
+Used by: kramdown parser
+
+
+.TP
+.B \-\-[no\-]html-to-native
+
+Convert HTML elements to native elements
+
+If this option is `true`, the parser converts HTML elements to native
+elements. For example, when parsing `<em>hallo</em>` the emphasis tag
+would normally be converted to an `:html` element with tag type `:em`.
+If `html_to_native` is `true`, then the emphasis would be converted to a
+native `:em` element.
+
+This is useful for converters that cannot deal with HTML elements.
+
+Default: false
+Used by: kramdown parser
+
+
+.TP
+.B \-\-link-defs ARG
+
+Pre-defines link definitions
+
+This option can be used to pre-define link definitions. The value needs
+to be a Hash where the keys are the link identifiers and the values are
+two element Arrays with the link URL and the link title.
+
+If the value is a String, it has to contain a valid YAML hash and the
+hash has to follow the above guidelines.
+
+Default: {}
+Used by: kramdown parser
+
+
+.TP
+.B \-\-footnote-nr ARG
+
+The number of the first footnote
+
+This option can be used to specify the number that is used for the first
+footnote.
+
+Default: 1
+Used by: HTML converter
+
+
+.TP
+.B \-\-[no\-]enable-coderay
+
+Use coderay for syntax highlighting
+
+If this option is `true`, coderay is used by the HTML converter for
+syntax highlighting the content of code spans and code blocks.
+
+Default: true
+Used by: HTML converter
+
+
+.TP
+.B \-\-coderay-wrap ARG
+
+Defines how the highlighted code should be wrapped
+
+The possible values are :span, :div or nil.
+
+Default: :div
+Used by: HTML converter
+
+
+.TP
+.B \-\-coderay-line-numbers ARG
+
+Defines how and if line numbers should be shown
+
+The possible values are :table, :inline or nil. If this option is
+nil, no line numbers are shown.
+
+Default: :inline
+Used by: HTML converter
+
+
+.TP
+.B \-\-coderay-line-number-start ARG
+
+The start value for the line numbers
+
+Default: 1
+Used by: HTML converter
+
+
+.TP
+.B \-\-coderay-tab-width ARG
+
+The tab width used in highlighted code
+
+Used by: HTML converter
+
+
+.TP
+.B \-\-coderay-bold-every ARG
+
+Defines how often a line number should be made bold
+
+Can either be an integer or false (to turn off bold line numbers
+completely).
+
+Default: 10
+Used by: HTML converter
+
+
+.TP
+.B \-\-coderay-css ARG
+
+Defines how the highlighted code gets styled
+
+Possible values are :class (CSS classes are applied to the code
+elements, one must supply the needed CSS file) or :style (default CSS
+styles are directly applied to the code elements).
+
+Default: style
+Used by: HTML converter
+
+
+.TP
+.B \-\-coderay-default-lang ARG
+
+Sets the default language for highlighting code blocks
+
+If no language is set for a code block, the default language is used
+instead. The value has to be one of the languages supported by coderay
+or nil if no default language should be used.
+
+Default: nil
+Used by: HTML converter
+
+
+.TP
+.B \-\-entity-output ARG
+
+Defines how entities are output
+
+The possible values are :as_input (entities are output in the same
+form as found in the input), :numeric (entities are output in numeric
+form), :symbolic (entities are output in symbolic form if possible) or
+:as_char (entities are output as characters if possible, only available
+on Ruby 1.9).
+
+Default: :as_char
+Used by: HTML converter, kramdown converter
+
+
+.TP
+.B \-\-toc-levels ARG
+
+Defines the levels that are used for the table of contents
+
+The individual levels can be specified by separating them with commas
+(e.g. 1,2,3) or by using the range syntax (e.g. 1..3). Only the
+specified levels are used for the table of contents.
+
+Default: 1..6
+Used by: HTML/Latex converter
+
+
+.TP
+.B \-\-line-width ARG
+
+Defines the line width to be used when outputting a document
+
+Default: 72
+Used by: kramdown converter
+
+
+.TP
+.B \-\-latex-headers ARG
+
+Defines the LaTeX commands for different header levels
+
+The commands for the header levels one to six can be specified by
+separating them with commas.
+
+Default: section,subsection,subsubsection,paragraph,subparagraph,subparagraph
+Used by: Latex converter
+
+
+.TP
+.B \-\-smart-quotes ARG
+
+Defines the HTML entity names or code points for smart quote output
+
+The entities identified by entity name or code point that should be
+used for, in order, a left single quote, a right single quote, a left
+double and a right double quote are specified by separating them with
+commas.
+
+Default: lsquo,rsquo,ldquo,rdquo
+Used by: HTML/Latex converter
+
+
+.TP
+.B \-\-[no\-]remove-block-html-tags
+
+Remove block HTML tags
+
+If this option is `true`, the RemoveHtmlTags converter removes
+block HTML tags.
+
+Default: true
+Used by: RemoveHtmlTags converter
+
+
+.TP
+.B \-\-[no\-]remove-span-html-tags
+
+Remove span HTML tags
+
+If this option is `true`, the RemoveHtmlTags converter removes
+span HTML tags.
+
+Default: false
+Used by: RemoveHtmlTags converter
+
+
+.TP
+.B \-\-header-offset ARG
+
+Sets the output offset for headers
+
+If this option is c (may also be negative) then a header with level n
+will be output as a header with level c+n. If c+n is lower than 1,
+level 1 will be used. If c+n is greater than 6, level 6 will be used.
+
+Default: 0
+Used by: HTML converter, Kramdown converter, Latex converter
+
+
+.TP
+.B \-\-[no\-]hard-wrap
+
+Interprets line breaks literally
+
+Insert HTML `<br />` tags inside paragraphs where the original Markdown
+document had newlines (by default, Markdown ignores these newlines).

+Adds a `__metaclass__` method to all Ruby objects.
+
+## Motivations
+
+* Even though WhyTheLuckyStiff's [metaid gem](https://rubygems.org/gems/metaid) does something similar, apparently the metaclass method without underscores [doesn't play well with Rails v2.3](https://github.com/floehopper/mocha/commit/f0749d6d291164cc9280aa8ba16f33d652d45fe1#commitcomment-475799).
+* I'm trying to extract code out of the [mocha gem](https://github.com/floehopper/mocha) and this is an obvious candidate.

+
+Minitest 5:
+
+* 4 deaths in the family:
+
+  * MiniTest.runner is dead. No more manager objects.
+  * MiniTest::Unit#record is dead. Use a Reporter instance instead.
+  * MiniTest::Unit._run_* is dead. Runnable things are responsible for their own runs.
+  * MiniTest::Unit.output is dead. No more centralized IO.
+
+* 12 major (oft incompatible) changes:
+
+  * Renamed MiniTest to Minitest. Your pinkies will thank me. (aliased to MiniTest)
+  * Removed MiniTest::Unit entirely. No more manager objects.
+  * Added Minitest::Runnable. Everything minitest can run subclasses this.
+  * Renamed MiniTest::Unit::TestCase to Minitest::Test (subclassing Runnable).
+  * Added Minitest::Benchmark.
+    * Your benchmarks need to move to their own subclass.
+    * Benchmarks using the spec DSL have to have "Bench" somewhere in their describe.
+  * MiniTest::Unit.after_tests moved to Minitest.after_tests
+  * MiniTest::Unit.autorun is now Minitest.autorun. Just require minitest/autorun pls.
+  * Removed ParallelEach#grep since it isn't used anywhere.
+  * Renamed Runnable#__name__ to Runnable#name (but uses @NAME internally).
+  * Runnable#run needs to return self. Allows for swapping of results as needed.
+
+* 8 minor moves:
+
+  * Moved Assertions module to minitest/assertions.rb
+  * Moved Expectations module to minitest/expectations.rb
+  * Moved Test to minitest/test.rb
+  * Moved everything else in minitest/unit.rb to minitest.rb
+  * minitest/unit.rb is now just a small (user-test only) compatibility layer.
+  * Moved most of minitest/pride into minitest/pride_plugin.
+  * minitest/pride now just activates pride.
+  * Moved ParallelEach under Minitest.
+
+* 9 additions:
+
+  * Added a plugin system that can extend command-line options.
+  * Added Minitest.extensions.
+  * Added Minitest.reporter (only available during startup).
+  * Added Minitest.run(args). This is the very top of any Minitest run.
+  * Added Minitest::Reporter. Everything minitest can report goes through here.
+    * Minitest.reporter is a composite so you can add your own.
+  * Added Minitest::CompositeReporter. Much easier to extend with your own reporters.
+  * Added UnexpectedError, an Assertion subclass, to wrap up errors.
+  * Minitest::Test#run is now freakin' beautiful. 47 -> 17 loc
+
+* 11 other:
+
+  * Removed Object.infect_with_assertions (it was already dead code).
+  * Runnables are responsible for knowing their result_code (eg "." or "F").
+  * Minitest.autorun now returns boolean, not exit code.
+  * Added FAQ entry for extending via modules. (phiggins)
+  * Implement Runnable#dup to cleanse state back to test results. Helps with serialization. pair:tenderlove

+  * Minitest.init_plugins passes down options.
+  * Minitest.load_plugins only loads once.

+  * Removed mutex from test.rb (phiggins)
+  * Removed Minitest::Reporter.synchronize (phiggins)
+  * Removed Minitest::Test.synchronize (phiggins)

+
+=== 4.7.4 / 2013-05-01
+
+This is probably the last release of the 4.x series. It will be merged
+to ruby and will be put into maintenance mode there.
+
+I'm not set in stone on this, but at this point further development of
+minitest (5+) will be gem-only. It is just too hard to work w/in
+ruby-core w/ test-unit compatibility holding minitest development
+back.

+
+== DESCRIPTION:
+
+minitest provides a complete suite of testing facilities supporting
+TDD, BDD, mocking, and benchmarking.
+
+    "I had a class with Jim Weirich on testing last week and we were
+     allowed to choose our testing frameworks. Kirk Haines and I were
+     paired up and we cracked open the code for a few test
+     frameworks...
+
+     I MUST say that minitest is *very* readable / understandable
+     compared to the 'other two' options we looked at. Nicely done and
+     thank you for helping us keep our mental sanity."
+
+    -- Wayne E. Seguin
+
+minitest/unit is a small and incredibly fast unit testing framework.
+It provides a rich set of assertions to make your tests clean and
+readable.
+
+minitest/spec is a functionally complete spec engine. It hooks onto
+minitest/unit and seamlessly bridges test assertions over to spec
+expectations.
+
+minitest/benchmark is an awesome way to assert the performance of your
+algorithms in a repeatable manner. Now you can assert that your newb
+co-worker doesn't replace your linear algorithm with an exponential
+one!
+
+minitest/mock by Steven Baker, is a beautifully tiny mock (and stub)
+object framework.
+
+minitest/pride shows pride in testing and adds coloring to your test
+output. I guess it is an example of how to write IO pipes too. :P
+
+minitest/unit is meant to have a clean implementation for language
+implementors that need a minimal set of methods to bootstrap a working
+test suite. For example, there is no magic involved for test-case
+discovery.
+
+    "Again, I can't praise enough the idea of a testing/specing
+     framework that I can actually read in full in one sitting!"
+
+    -- Piotr Szotkowski
+
+Comparing to rspec:
+
+    rspec is a testing DSL. minitest is ruby.
+
+    -- Adam Hawkins, "Bow Before MiniTest"
+
+minitest doesn't reinvent anything that ruby already provides, like:
+classes, modules, inheritance, methods. This means you only have to
+learn ruby to use minitest and all of your regular OO practices like
+extract-method refactorings still apply.
+
+== FEATURES/PROBLEMS:
+
+* minitest/autorun - the easy and explicit way to run all your tests.
+* minitest/unit - a very fast, simple, and clean test system.
+* minitest/spec - a very fast, simple, and clean spec system.
+* minitest/mock - a simple and clean mock/stub system.
+* minitest/benchmark - an awesome way to assert your algorithm's performance.
+* minitest/pride - show your pride in testing!
+* Incredibly small and fast runner, but no bells and whistles.
+
+== RATIONALE:
+
+See design_rationale.rb to see how specs and tests work in minitest.
+
+== SYNOPSIS:
+
+Given that you'd like to test the following class:
+
+  class Meme
+    def i_can_has_cheezburger?
+      "OHAI!"
+    end
+
+    def will_it_blend?
+      "YES!"
+    end
+  end
+
+=== Unit tests
+
+Define your tests as methods beginning with `test_`.
+
+  require "minitest/autorun"
+
+  class TestMeme < Minitest::Test
+    def setup
+      @meme = Meme.new
+    end
+
+    def test_that_kitty_can_eat
+      assert_equal "OHAI!", @meme.i_can_has_cheezburger?
+    end
+
+    def test_that_it_will_not_blend
+      refute_match /^no/i, @meme.will_it_blend?
+    end
+
+    def test_that_will_be_skipped
+      skip "test this later"
+    end
+  end
+
+=== Specs
+
+  require "minitest/autorun"
+
+  describe Meme do
+    before do
+      @meme = Meme.new
+    end
+
+    describe "when asked about cheeseburgers" do
+      it "must respond positively" do
+        @meme.i_can_has_cheezburger?.must_equal "OHAI!"
+      end
+    end
+
+    describe "when asked about blending possibilities" do
+      it "won't say no" do
+        @meme.will_it_blend?.wont_match /^no/i
+      end
+    end
+  end
+
+For matchers support check out:
+
+https://github.com/wojtekmach/minitest-matchers
+https://github.com/rmm5t/minitest-matchers_vaccine
+
+=== Benchmarks
+
+Add benchmarks to your tests.
+
+  # optionally run benchmarks, good for CI-only work!
+  require "minitest/benchmark" if ENV["BENCH"]
+
+  class TestMeme < Minitest::Benchmark
+    # Override self.bench_range or default range is [1, 10, 100, 1_000, 10_000]
+    def bench_my_algorithm
+      assert_performance_linear 0.9999 do |n| # n is a range value
+        @obj.my_algorithm(n)
+      end
+    end
+  end
+
+Or add them to your specs. If you make benchmarks optional, you'll
+need to wrap your benchmarks in a conditional since the methods won't
+be defined. In minitest 5, the describe name needs to match
+/Bench(mark)?$/.
+
+  describe "Meme Benchmark" do
+    if ENV["BENCH"] then
+      bench_performance_linear "my_algorithm", 0.9999 do |n|
+        100.times do
+          @obj.my_algorithm(n)
+        end
+      end
+    end
+  end
+
+outputs something like:
+
+  # Running benchmarks:
+
+  TestBlah	100	1000	10000
+  bench_my_algorithm	 0.006167	 0.079279	 0.786993
+  bench_other_algorithm	 0.061679	 0.792797	 7.869932
+
+Output is tab-delimited to make it easy to paste into a spreadsheet.
+
+=== Mocks
+
+Mocks and stubs defined using terminology by Fowler & Meszaros at
+http://www.martinfowler.com/bliki/TestDouble.html:
+
+"Mocks are pre-programmed with expectations which form a specification
+of the calls they are expected to receive. They can throw an exception
+if they receive a call they don't expect and are checked during
+verification to ensure they got all the calls they were expecting."
+
+  class MemeAsker
+    def initialize(meme)
+      @meme = meme
+    end
+
+    def ask(question)
+      method = question.tr(" ", "_") + "?"
+      @meme.__send__(method)
+    end
+  end
+
+  require "minitest/autorun"
+
+  describe MemeAsker, :ask do
+    describe "when passed an unpunctuated question" do
+      it "should invoke the appropriate predicate method on the meme" do
+        @meme = Minitest::Mock.new
+        @meme_asker = MemeAsker.new @meme
+        @meme.expect :will_it_blend?, :return_value
+
+        @meme_asker.ask "will it blend"
+
+        @meme.verify
+      end
+    end
+  end
+
+=== Stubs
+
+Mocks and stubs are defined using terminology by Fowler & Meszaros at
+http://www.martinfowler.com/bliki/TestDouble.html:
+
+"Stubs provide canned answers to calls made during the test".
+
+Minitest's stub method overrides a single method for the duration of
+the block.
+
+  def test_stale_eh
+    obj_under_test = Something.new
+
+    refute obj_under_test.stale?
+
+    Time.stub :now, Time.at(0) do   # stub goes away once the block is done
+      assert obj_under_test.stale?
+    end
+  end
+
+A note on stubbing: In order to stub a method, the method must
+actually exist prior to stubbing. Use a singleton method to create a
+new non-existing method:
+
+  def obj_under_test.fake_method
+    ...
+  end
+
+=== Running Your Tests
+
+Ideally, you'll use a rake task to run your tests, either piecemeal or
+all at once. Both rake and rails ship with rake tasks for running your
+tests. BUT! You don't have to:
+
+    % ruby -Ilib:test test/minitest/test_minitest_unit.rb
+    Run options: --seed 37685
+
+    # Running:
+
+    ...................................................................... (etc)
+
+    Finished in 0.107130s, 1446.8403 runs/s, 2959.0217 assertions/s.
+
+    155 runs, 317 assertions, 0 failures, 0 errors, 0 skips
+
+There are runtime options available, both from minitest itself, and also
+provided via plugins. To see them, simply run with `--help`:
+
+    % ruby -Ilib:test test/minitest/test_minitest_unit.rb --help
+    minitest options:
+        -h, --help                       Display this help.
+        -s, --seed SEED                  Sets random seed
+        -v, --verbose                    Verbose. Show progress processing files.
+        -n, --name PATTERN               Filter run on /pattern/ or string.
+
+    Known extensions: pride, autotest
+        -p, --pride                      Pride. Show your testing pride!
+        -a, --autotest                   Connect to autotest server.
+
+== Writing Extensions
+
+To define a plugin, add a file named minitest/XXX_plugin.rb to your
+project/gem. That file must be discoverable via ruby's LOAD_PATH (via
+rubygems or otherwise). Minitest will find and require that file using
+Gem.find_files. It will then try to call plugin_XXX_init during
+startup. The option processor will also try to call plugin_XXX_options
+passing the OptionParser instance and the current options hash. This
+lets you register your own command-line options. Here's a totally
+bogus example:
+
+    # minitest/bogus_plugin.rb:
+
+    module Minitest
+      def self.plugin_bogus_options(opts, options)
+        opts.on "--myci", "Report results to my CI" do
+          options[:myci] = true
+          options[:myci_addr] = get_myci_addr
+          options[:myci_port] = get_myci_port
+        end
+      end
+
+      def self.plugin_bogus_init(options)
+        self.reporter << MyCI.new(options) if options[:myci]
+      end
+    end
+
+=== Adding custom reporters
+
+Minitest uses composite reporter to output test results using multiple
+reporter instances. You can add new reporters to the composite during
+the init_plugins phase. As we saw in +plugin_bonus_init+ above, you
+simply add your reporter instance to the composite via +<<+.
+
++AbstractReporter+ defines the API for reporters. You may subclass it
+and override any method you want to achieve your desired behavior.
+
+start   :: Called when the run has started.
+record  :: Called for each result, passed or otherwise.
+report  :: Called at the end of the run.
+passed? :: Called to see if you detected any problems.
+
+Using our example above, here is how we might implement MyCI:
+
+    # minitest/bogus_plugin.rb
+
+    module Minitest
+      class MyCI < AbstractReporter
+        attr_accessor :results, :addr, :port
+
+        def initialize options
+          self.results = []
+          self.addr = options[:myci_addr]
+          self.port = options[:myci_port]
+        end
+
+        def record result
+          self.results << result
+        end
+
+        def report
+          CI.connect(addr, port).send_results self.results
+        end
+      end
+
+      # code from above...
+    end
+
+== FAQ
+
+=== How to test SimpleDelegates?
+
+The following implementation and test:
+
+    class Worker < SimpleDelegator
+      def work
+      end
+    end
+
+    describe Worker do
+      before do
+        @worker = Worker.new(Object.new)
+      end
+
+      it "must respond to work" do
+        @worker.must_respond_to :work
+      end
+    end
+
+outputs a failure:
+
+      1) Failure:
+    Worker#test_0001_must respond to work [bug11.rb:16]:
+    Expected #<Object:0x007f9e7184f0a0> (Object) to respond to #work.
+
+Worker is a SimpleDelegate which in 1.9+ is a subclass of BasicObject.
+Expectations are put on Object (one level down) so the Worker
+(SimpleDelegate) hits `method_missing` and delegates down to the
+`Object.new` instance. That object doesn't respond to work so the test
+fails.
+
+You can bypass `SimpleDelegate#method_missing` by extending the worker
+with `Minitest::Expectations`. You can either do that in your setup at
+the instance level, like:
+
+    before do
+      @worker = Worker.new(Object.new)
+      @worker.extend Minitest::Expectations
+    end
+
+or you can extend the Worker class (within the test file!), like:
+
+    class Worker
+      include ::Minitest::Expectations
+    end
+
+=== How to share code across test classes?
+
+Use a module. That's exactly what they're for:
+
+    module UsefulStuff
+      def useful_method
+        # ...
+      end
+    end
+
+    describe Blah do
+      include UsefulStuff
+
+      def test_whatever
+        # useful_method available here
+      end
+    end
+
+Remember, `describe` simply creates test classes. It's just ruby at
+the end of the day and all your normal Good Ruby Rules (tm) apply. If
+you want to extend your test using setup/teardown via a module, just
+make sure you ALWAYS call super. before/after automatically call super
+for you, so make sure you don't do it twice.
+
+=== Why am I seeing `uninitialized constant MiniTest::Test (NameError)`?
+
+Are you running the test with Bundler (e.g. via `bundle exec`)? If so, 
+in order to require minitest, you must first add the `gem 'minitest'`
+to your Gemfile and run `bundle`. Once it's installed, you should be 
+able to require minitest and run your tests.
+
+== Prominent Projects using Minitest:
+
+* arel
+* journey
+* mime-types
+* nokogiri
+* rails (active_support et al)
+* rake
+* rdoc
+* ...and of course, everything from seattle.rb...

+
+== REQUIREMENTS:
+
+* Ruby 1.8.7+. No magic is involved. I hope.
+
+== INSTALL:
+
+  sudo gem install minitest
+
+On 1.9, you already have it. To get newer candy you can still install
+the gem, and then requiring "minitest/autorun" should automatically
+pull it in. If not, you'll need to do it yourself:
+
+  gem "minitest"     # ensures you"re using the gem, and not the built-in MT
+  require "minitest/autorun"
+
+  # ... usual testing stuffs ...
+
+DO NOTE: There is a serious problem with the way that ruby 1.9/2.0
+packages their own gems. They install a gem specification file, but
+don't install the gem contents in the gem path. This messes up
+Gem.find_files and many other things (gem which, gem contents, etc).
+
+Just install minitest as a gem for real and you'll be happier.

+## Mocha [![build status](https://secure.travis-ci.org/freerange/mocha.png)](https://secure.travis-ci.org/freerange/mocha) [![Gem Version](https://badge.fury.io/rb/mocha.png)](http://badge.fury.io/rb/mocha)
+
+### Description
+
+* A Ruby library for mocking and stubbing.
+* A unified, simple and readable syntax for both full & partial mocking.
+* Built-in support for MiniTest and Test::Unit.
+* Supported by many other test frameworks.
+
+### Installation
+
+#### Gem
+
+Install the latest version of the gem with the following command...
+
+    $ gem install mocha
+
+Note: If you are intending to use Mocha with Test::Unit or MiniTest, you should only setup Mocha *after* loading the relevant test library...
+
+##### Test::Unit
+
+```ruby
+require 'rubygems'
+gem 'mocha'
+require 'test/unit'
+require 'mocha/test_unit'
+```
+
+##### MiniTest
+
+```ruby
+require 'rubygems'
+gem 'mocha'
+require 'minitest/unit'
+require 'mocha/mini_test'
+```
+
+#### Bundler
+
+If you're using Bundler, include Mocha in the `Gemfile` and then setup Mocha later once you know the test library has been loaded...
+
+##### Test::Unit
+
+```ruby
+# Gemfile
+gem "mocha"
+
+# Elsewhere after Bundler has loaded gems e.g. after `require 'bundler/setup'`
+require "test/unit"
+require "mocha/test_unit"
+```
+
+##### MiniTest
+
+```ruby
+# Gemfile
+gem "mocha"
+
+# Elsewhere after Bundler has loaded gems e.g. after `require 'bundler/setup'`
+require "minitest/unit"
+require "mocha/mini_test"
+```
+
+#### Rails
+
+If you're loading Mocha using Bundler within a Rails application, you should setup Mocha manually e.g. at the bottom of your `test_helper.rb`.
+
+##### MiniTest
+
+```ruby
+# Gemfile in Rails app
+gem 'mocha'
+
+# At bottom of test_helper.rb (or at least after `require 'rails/test_help'`)
+require 'mocha/mini_test'
+```
+
+#### Rails Plugin
+
+Install the Rails plugin...
+
+    $ rails plugin install git://github.com/freerange/mocha.git
+
+Note: As of version 0.9.8, the Mocha plugin is not automatically setup at plugin load time. Instead it must be manually setup e.g. at the bottom of your `test_helper.rb`.
+
+##### MiniTest
+
+```ruby
+# At bottom of test_helper.rb (or at least after `require 'rails/test_help'`)
+require 'mocha/mini_test'
+```
+
+#### Know Issues
+
+* 0.13.x versions cause a harmless, but annoying, deprecation warning when used with Rails 3.2.0-3.2.12, 3.1.0-3.1.10 & 3.0.0-3.0.19.
+* 0.11.x versions don't work with Rails 3.2.13 (`TypeError: superclass mismatch for class ExpectationError`). See #115.
+* Versions 0.10.2, 0.10.3 & 0.11.0 of the Mocha gem were broken. Please do not use these versions.
+* Versions 0.9.6 & 0.9.7 of the Mocha Rails plugin were broken. Please do not use these versions.
+
+### Usage
+
+#### Quick Start
+
+```ruby
+require 'test/unit'
+require 'mocha/test_unit'
+
+class MiscExampleTest < Test::Unit::TestCase
+  def test_mocking_a_class_method
+    product = Product.new
+    Product.expects(:find).with(1).returns(product)
+    assert_equal product, Product.find(1)
+  end
+
+  def test_mocking_an_instance_method_on_a_real_object
+    product = Product.new
+    product.expects(:save).returns(true)
+    assert product.save
+  end
+
+  def test_stubbing_instance_methods_on_real_objects
+    prices = [stub(:pence => 1000), stub(:pence => 2000)]
+    product = Product.new
+    product.stubs(:prices).returns(prices)
+    assert_equal [1000, 2000], product.prices.collect {|p| p.pence}
+  end
+
+  def test_stubbing_an_instance_method_on_all_instances_of_a_class
+    Product.any_instance.stubs(:name).returns('stubbed_name')
+    product = Product.new
+    assert_equal 'stubbed_name', product.name
+  end
+
+  def test_traditional_mocking
+    object = mock('object')
+    object.expects(:expected_method).with(:p1, :p2).returns(:result)
+    assert_equal :result, object.expected_method(:p1, :p2)
+  end
+
+  def test_shortcuts
+    object = stub(:method1 => :result1, :method2 => :result2)
+    assert_equal :result1, object.method1
+    assert_equal :result2, object.method2
+  end
+end
+```
+
+#### Mock Objects
+
+```ruby
+class Enterprise
+  def initialize(dilithium)
+    @dilithium = dilithium
+  end
+
+  def go(warp_factor)
+    warp_factor.times { @dilithium.nuke(:anti_matter) }
+  end
+end
+
+require 'test/unit'
+require 'mocha/test_unit'
+
+class EnterpriseTest < Test::Unit::TestCase
+  def test_should_boldly_go
+    dilithium = mock()
+    dilithium.expects(:nuke).with(:anti_matter).at_least_once  # auto-verified at end of test
+    enterprise = Enterprise.new(dilithium)
+    enterprise.go(2)
+  end
+end
+```
+
+#### Partial Mocking
+
+```ruby
+class Order
+  attr_accessor :shipped_on
+
+  def total_cost
+    line_items.inject(0) { |total, line_item| total + line_item.price } + shipping_cost
+  end
+
+  def total_weight
+    line_items.inject(0) { |total, line_item| total + line_item.weight }
+  end
+
+  def shipping_cost
+    total_weight * 5 + 10
+  end
+
+  class << self
+    def find_all
+      # Database.connection.execute('select * from orders...
+    end
+  
+    def number_shipped_since(date)
+      find_all.select { |order| order.shipped_on > date }.length
+    end
+
+    def unshipped_value
+      find_all.inject(0) { |total, order| order.shipped_on ? total : total + order.total_cost }
+    end
+  end
+end
+
+require 'test/unit'
+require 'mocha/test_unit'
+
+class OrderTest < Test::Unit::TestCase
+  # illustrates stubbing instance method
+  def test_should_calculate_shipping_cost_based_on_total_weight
+    order = Order.new
+    order.stubs(:total_weight).returns(10)
+    assert_equal 60, order.shipping_cost
+  end
+
+  # illustrates stubbing class method
+  def test_should_count_number_of_orders_shipped_after_specified_date
+    now = Time.now; week_in_secs = 7 * 24 * 60 * 60
+    order_1 = Order.new; order_1.shipped_on = now - 1 * week_in_secs
+    order_2 = Order.new; order_2.shipped_on = now - 3 * week_in_secs
+    Order.stubs(:find_all).returns([order_1, order_2])
+    assert_equal 1, Order.number_shipped_since(now - 2 * week_in_secs)
+  end
+
+  # illustrates stubbing instance method for all instances of a class
+  def test_should_calculate_value_of_unshipped_orders
+    Order.stubs(:find_all).returns([Order.new, Order.new, Order.new])
+    Order.any_instance.stubs(:shipped_on).returns(nil)
+    Order.any_instance.stubs(:total_cost).returns(10)
+    assert_equal 30, Order.unshipped_value
+  end
+end
+```

+### Thread safety
+
+Mocha is currently *not* thread-safe. There are two main reasons for this: (a) in multi-threaded code Mocha exceptions may be raised in a thread other than the one which is running the test and thus a Mocha exception may not be correctly intercepted by Mocha exception handling code; and (b) partial mocking changes the state of objects in the `ObjectSpace` which is shared across all threads in the Ruby process and this access to what is effectively global state is not synchronized.
+
+### Expectation matching / invocation order
+
+Stubs and expectations are basically the same thing. A stub is just an expectation of zero or more invocations. The `Expectation#stubs` method is syntactic sugar to make the intent of the test more explicit.
+
+When a method is invoked on a mock object, the mock object searches through its expectations from newest to oldest to find one that matches the invocation. After the invocation, the matching expectation might stop matching further invocations.
+
+See the [documentation](http://gofreerange.com/mocha/docs/Mocha/Mock.html) for `Mocha::Mock` for further details.

+# Release Notes
+
+## 1.1.0
+
+* Set visibility of any instance stub method.
+* Stub methods with a prepended method if there are other prepended methods. Thanks to @mrsimo.
+* Improve docs for `Mock#responds_like` & `#responds_like_instance_of`.
+* Use GitHub convention for instructions on contributing to Mocha.
+* Fix typos in docs. Thanks to @10io
+
+## 1.0.0
+
+### External changes
+* Assume 'mocha' has been required when requiring 'mocha/setup'.
+* Provide shortcuts for integrating with specific test library i.e. `require 'mocha/test_unit'` or `require 'mocha/mini_test'`
+as alternatives to `require 'mocha/setup'`.
+* Do not automatically try to integrate with test libraries. Since the automatic test library integration functionality
+requires the test library to be loaded and this doesn't usually happen until *after* the bundle is loaded, it makes things
+simpler if we use `require 'mocha/setup'` to explicitly setup Mocha when we know the test library has been loaded. Fixes #146 & #155.
+* Consider stubs on superclasses if none exist on primary receiver. Largely based on changes suggested by @ccutrer in #145.
+Note: this may break existing tests which rely on the old behaviour. Stubbing a superclass method and then invoking that
+method on a child class would previously cause an unexpected invocation error. By searching up through the inheritance
+hierarchy for each of the delegate mock objects, we can provide more intuitive behaviour. Instead of an unexpected invocation
+error, invoking the method on the child class will cause the stubbed method on the superclass to be used.
+* Avoid recursion when constructing unexpected invocation message. Fixes #168.
+* Add explanation of method dispatch. Heavily based on the relevant jMock v1 documentation. Fixes #172.
+* Make class_eval line number more accurate. This sets the line number as the line number of the `def` statement. Closes #169.
+* Allow nesting of `responds_with` parameter matcher. Closes #166.
+* Define `Mocha` module before it's referenced. The test helper defines a class `TestCase` within the `Mocha` module. When
+running the tests inside the bundle, the `Mocha` module happens to be defined at this point. However when running the tests outside the bundle, it is not defined and so an exception is raised: `uninitialized constant Mocha (NameError)`. Fixes #163.
+* Document lack of thread-safety. Fixes #154.
+* Document how to use the build-matrix script. Fixes #160.
+* Stubbing non-public method should use same visibility. This will probably break some existing tests that were somehow relying
+on the stubbed method being public while the original method was protected or private. Fixes #150.
+
+### Internal changes
+* Use lastest Rubygems in Travis CI builds.
+* Run the standard test suite against Ruby 2.1.0 in the build matrix.
+* Run integration tests against Ruby 2.0.0 with latest Test::Unit gem in the build matrix.
+* Test::Unit is not available in Ruby v1.9.3 standard library, so remove it from the build matrix.
+* Force use of Test::Unit runner, etc in relevant integration tests. Prior to this, I don't think we were really testing the
+Mocha integration with Test::Unit much, because, although `TestUnitTest` was a subclass of `Test::Unit::TestCase`, the
+important test case instances are the temporary ones built by `TestRunner#run_as_test` et al. Prior to this change, these
+would only have used Test::Unit where MiniTest was not available *at all* i.e. only in early versions of Ruby and when the
+MiniTest gem was not loaded.
+* Reset environment variables between build matrix builds.
+* Only activate integration with relevant test library for each of the integration tests.
+* Include standard build combinations from Travis CI config i.e. builds using standard library versions of test libraries.
+* Fix `build-matrix.rb` script. Also use `.travis.yml` to decide what combinations to run. This means we
+can now simulate the Travis CI build locally and avoid duplication. Fixes #157.
+* Remove Ruby version map from build matrix script. I'm using the `rbenv-aliases` plugin to alias minor versions to the
+relevant patch version.
+
+## 0.14.0
+
+* Official support for MiniTest v5. All tests now pass on the continuous integration build.
+
+## 0.14.0.alpha
+
+* Add speculative support for Minitest v5. Due to incompatibilities it has not yet been possible to run the Mocha test suite against Minitest v5. However, @zenspider (author of Minitest) provided the patch and he has tested it against Rails v4. Fixes #156. Thanks to @zenspider.
+* Documentation updates.
+
+## 0.13.3
+* Allow `Mocha::ParameterMatchers#includes` to accept multiple items. Thanks to @simao.
+* Allow stubbing of *private* `Kernel` methods. Fixes #134. Thanks to @camski for reporting.
+* Avoid a warning when `test/unit/version` is required by other libraries in the same project. Fixes #140. Thanks to @tmiller.
+* Make auto-activation of Test::Unit integration more resilient. This change is specifically to cope with the nasty re-defining of classes that is done by the `minitest-spec-rails` gem. Fixes #143. Thanks to @tubaxenor for reporting.
+* Safer restoration of stubbed method visibility. Fixes #141. Thanks to @tmm1.
+* Ensure `Mockery` instance gets reset even if exception raised. Fixes #144.
+* Adapt Mocha acceptance tests to cope with changes in output from latest (v4.6.2) of MiniTest.
+* Updates to README about Rails compatibility.
+
+## 0.13.2
+* Stubbing of methods re-declared with different visibilty. Fixes #109.
+* Add `Mock#responds_like_instance_of`. Fixes #119.
+* Make `Expectation#inspect` less verbose and more useful. Fixes #122.
+* Make unit tests more robust to changes in environment. Fixes #121.
+* Update README in an attempt to head Rails-related issues off at the pass.
+* Add a Gem Badge to provide a link to Mocha on Rubygems.
+* Make documentation example consistent with other examples.
+
+## 0.13.1
+* Fix #97 - `Mocha::ParameterMatchers#has_entry` does not work with an Array as the entry's value. Thanks to @ngokli.
+* Allow deprecation `:debug` mode to be switched on from `MOCHA_OPTIONS` environment variable.
+
+## 0.13.0
+* Major overhaul of MiniTest & Test::Unit integration. Mocha now integrates with later versions of the two test libraries using documented hooks rather than monkey-patching. This should mean that Mocha will integrate with new versions of either library without the need to release a new version of Mocha each time, which was clearly bad and unsustainable. Many thanks to @tenderlove, @zenspider & @kou for their help, suggestions & patience.
+* Temporarily deprecated `require 'mocha'`. Use `require 'mocha/setup'` instead. The plan is that eventually `require 'mocha'` will *not* automatically integrate with either of the two test libraries as it does at the moment, and you'll need to explicitly & separately trigger the integration. I think this will provide a lot more flexibility and will hopefully do away with the need for the `require: false` option in the `Gemfile` which has always confused people.
+* Deprecated `require 'mocha_standalone'` and `require 'mocha/standalone'`. Use `require 'mocha/api` instead.
+* Although these are not part of Mocha's public API, I thought I should mention that the MiniTest and Test::Unit assertion counter classes have been combined into a single class `Mocha::Integration::AssertionCounter`.
+* Extracted Mocha::Hooks module from Mocha::API and added documentation for test library authors.
+* Improvements to documentation. Much of it has been combined into the README file.
+* Fix #101 - Mock#respond_to? doesn't work with a string argument - thanks to @urbanautomaton.
+* Fix #105 - Travis link in README - thanks to @cknadler.
+* Various improvements to automated testing of integration with test libraries.
+* Make deprecation warnings more prominent.
+
+## 0.12.7
+* Officially support minitest v4.1.0 (still monkey-patching).
+
+## 0.12.6
+* Fixes #103.
+
+## 0.12.5
+* Officially support minitest v3.5.0 (still monkey-patching).
+
+## 0.12.4
+* Officially support minitest v3.4.0 & test-unit v2.5.2 (still monkey-patching).
+
+## 0.12.3
+* Revert rename of undocumented internal module since it turns out Rails/ActiveSupport is relying on its existence.
+
+## 0.12.2
+* Officially support minitest v3.3.0 (still monkey-patching)
+
+## 0.12.1
+* Deprecation warning (instead of fail fast) if neither Test::Unit nor MiniTest is loaded. Fixes #88.
+* Remove deprecated access to `Mocha::Standalone`.
+* Remove the deprecated file `stubba.rb`.
+* Officially support test-unit v2.5.1 (still monkey-patching).
+* Improve the API acceptance test.
+
+## 0.12.0
+* Fail fast if neither Test::Unit nor MiniTest is loaded. Fixes #40.
+* Officially support MiniTest up to v3.2.0 (still monkey-patching).
+* Officially support test-unit v2.5.0 (still monkey-patching).
+* Do not monkey-patch Test::Unit or MiniTest unless we *know* it's ok.
+* Add acceptance tests to demonstrate using a block as a custom parameter matcher.
+* Update Travis CI build status image to use the new build under the freerange account.
+
+## 0.11.4
+* Homepage has moved to http://gofreerange.com/mocha/docs.
+
+## 0.11.3
+* Fix for #78 i.e. alias Object#method as Object#_method, not Object#__method__ which already exists as another Ruby method.
+
+## 0.11.2
+* Rails has a Request class which defines its own #method method. This broke the new mechanism for stubbing a method. This release includes a slightly modified version of fix #77 provided by @sikachu. See https://github.com/rails/rails/pull/5907 for further info.
+
+## 0.11.1
+* In Ruby 1.8.7 methods accepting a block parameter were incorrectly restored without the block parameter after being stubbed. Fix for #76.
+
+## 0.11.0
+* Store original method when stubbing rather than using alias_method. This fixes #41, #47, #74 and all tests now pass on both Ruby 1.8.7 and 1.9.3.
+* Attempting to stub a method on a frozen object should fail fast. See #68.
+* Prevent stubbing a method on nil by default. See #68.
+* Generate documentation using YARD instead of Rdoc - removes dependency on Coderay.
+* Publish documentation on Github pages instead of Rubyforge - uses rake task written by @tomafro.
+* Remove agiledox which has outlived it's usefulness.
+* Removed trailing whitespace throughout codebase.
+* Add documentation for Mock#unstub.
+* Improve documentation for ObjectMethods.
+* Provide a way to run multiple tests within a single acceptance test method.
+
+## 0.10.5
+* Fix for issue #66 (hopefully without regressing on issue #63) - Mocha::Mock has Mocha::Mockery as a dependency. Stop trying to pretend otherwise. Thanks to @kennyj for reporting.
+* Fix a bunch of warnings in Ruby 1.9. There are still the 6 test failures mentioned in issue #41 which I suspect are due to the introspection gem not being Ruby 1.9-compatible.
+* Add links to README for source code & issue tracker.
+* Fix for issue #67 - Make the travis-ci badge visible in the README. Thanks to Diego Plentz for pull request.
+* Fix for issue #70 - Rename Mock#expectations to Mock#__expectations__ to avoid conflicts. Thanks to Jeremy Stephens for pull request.
+
+## 0.10.4
+* Fix for issue #65 - expectations not being verified in subsequent tests.
+* Fix for issue #63 - require Mocha::Mockery at Mocha::Mock class load time and not on invocation of Mock#method_missing.
+* Fix for issue #45 - raise ArgumentError if Mocha::ParameterMatchers#has_entry is given
+Hash with wrong number of entries.
+* Make global variable name more obscure to avoid clashes with other libraries.
+* Move travis-ci-related gemfiles into their own directory.
+
+## 0.10.3
+* Fix for issue #57. Gem::Requirement#=~ was only added in rubygems v1.8.0, but Object#=~ means the result of various monkey-patching checks is always false/nil for earlier versions of rubygems. However, the method it aliases #satisfied_by? has existed since Gem::Dependency was extracted from Gem::Version in rubygems v0.9.4.4, so it's much safer to use that. Thanks to fguillen for reporting and helping with diagnosis.
+
+## 0.10.2
+* Merge pull request #53. Unstubbing a method should not remove expectations for other stubbed methods. Fixes #52. Thanks to saikat.
+
+## 0.10.1
+* Merge pull request #51. Use Gem::Requirement & Gem::Version for version comparison. Fixes issue #50. Thanks to meineerde.
+* Fixed typo in rdoc for Mocha::ObjectMethods.
+* Improve README as suggested in issue #46. Explain that Mocha must be loaded after test libraries and how to achieve this using Bundler.
+* Merge pull request #43 - nobody expects the spanish inquisition! Thanks to cairo140.
+* Fix for issue #39 - improve documentation for Expectation#multiple_yields.
+* Fix for issue #38 where a subtle change in test-unit v2.3.0 had been missed - only visible in verbose mode.
+* Support for MiniTest up to v2.6.2 has been verified.
+* Add explicit development dependency on coderay for generating syntax-highlighted code examples.
+
+## 0.10.0
+* Add Expectation#throws to allow a stubbed method to use Kernel#throw.
+* Updates for versions of Test::Unit up to and including v2.3.3 (including patch by Jens Fahnenbruck).
+* Updates for versions of MiniTest up to and including v2.5.1.
+* Since the singleton method added by Mocha masks the underlying instance method, there's no need to move it out the way and then back again. This fixes Github issue #20, because the original method is left unchanged - https://github.com/floehopper/mocha/issues/20 (thanks to Nick Lewis).
+* Handle stubbing of a singleton method, leaving the original method unchanged after the test.
+* When stubbing an instance method that was originally defined as a singleton method, the original method should still exist after the test.
+* Fixed mis-print in Mocha::ObjectMethods#unstub documentation (patch by Gleb Pomykalov).
+* Improved test coverage around stubbing of methods defined in different ways - this makes use of the newly extracted introspection gem (although this means some tests are now failing in Ruby v1.9.2).
+* Added configuration for Travis continuous integration.
+* Make the gemspec the canonical reference and stop generating it from the Rakefile.
+* Use the built-in Bundler rake tasks for packaging the gem.
+* Use the "release" rake task provided by Bundler instead of using the Rake::XForge::Release functionality.
+* Extract Object#__metaclass__ into a new metaclass gem.
+* Run rake tasks without `bundle exec`.
+* Avoid deprecation warning for rdoc rake task.
+* Remove the `use_test_unit_gem` MOCHA_OPTION which hasn't worked since we switched to bundler - we can now run the tests specifying a different Gemfile instead.
+* Use multiple Gemfiles seems to run Travis CI builds against multiple version of test-unit & minitest.
+
+## 0.9.12
+* Make Mocha's tests pass under Ruby 1.9.2 i.e. using MiniTest. One of the main issues was that we were not parsing stacktraces on MiniTest errors comprehensively enough.
+* Avoid 'circular require considered harmful' warning when running Mocha's tests in Ruby 1.9.2
+* Make performance tests work on Ruby 1.9.2 i.e. using MiniTest.
+* Declare rake as a *development* dependency with newer versions of Rubygems since it's only needed to carry out developer-related tasks.
+
+## 0.9.11
+* Added explicit support for minitest v1.5.0 to v2.0.2.
+* Make testable by rubygems-test.
+* Update links to my blog and make other links consistent.
+* Added a URI parameter matcher that ignores the order of query parameters so that tests can be independent of undefined hash ordering (patch by Paul Battley).
+* Include unexpected invocation in failure message and change the language slightly to make the failure message less confusing. See http://floehopper.lighthouseapp.com/projects/22289/tickets/52.
+* No need to create regular expression every time the BacktraceFilter#filtered method is called. See http://floehopper.lighthouseapp.com/projects/22289-mocha/tickets/66.
+
+## 0.9.10
+* Added Mocha::ObjectMethods#unstub method - https://github.com/floehopper/mocha/issues#issue/6
+* Inherit Mocha::ExpectationError from Exception instead of StandardError to reduce the chances of a test passing by accident - thanks to James Sanders (jsanders) - https://github.com/floehopper/mocha/issues#issue/15
+* Fixed bug - GitHub README page to link correctly to code examples - https://github.com/floehopper/mocha/issues/closed#issue/11
+* Fixed bug - PASSTHROUGH_EXCEPTIONS are defined on MiniTest::Unit::TestCase not in Mocha - thanks to Brian Troutwine (blt) - https://github.com/floehopper/mocha/issues/closed#issue/14
+
+## 0.9.9
+* Avoid loading bits of the test-unit gem by accident. This is an attempt at a fix for the problem that James Adam reported [1]. By using 'load' instead of 'require' to detect the version of Test::Unit, we can avoid rubygems trying to load bits of the test-unit gem when it's not wanted. [1] http://floehopper.lighthouseapp.com/projects/22289-mocha/tickets/50#ticket-50-13
+* Fix exception when running rake without test-unit gem. When test-unit gem >=v2.0.0 was installed but the "use_test_unit_gem" MOCHA_OPTIONS was not specified, a "comparison of Fixnum with Hash failed" exception was being raised when running the performance tests. This was because bits of the test-unit gem were being loaded accidentally and a Hash was being incorrectly supplied to the TestRunner.run method.
+* Explicitly require rubygems for running tests via rake using test-unit gem.
+* Handle newer versions of test-unit gem (v2.0.2 to v2.0.9)
+* Handle newer versions of minitest gem (v1.4.0 to v1.6.0)
+* Added warnings about monkey-patching test-unit and minitest to aid debugging. These are enabled by including "debug" in the MOCHA_OPTIONS environment variable. This is now a comma-separated list, so that we can specify multiple options e.g. MOCHA_OPTIONS=debug,use_test_unit_gem
+* Eloy Duran (alloy) made the unit tests run on 1.9.2dev r25249.
+* Eloy Duran (alloy) also improved some MiniTest TestResult code I'd written and got the acceptance tests running on Ruby 1.9 HEAD. There are still 4 failures because for some reason the backtrace line numbers are off by one. And the minitest_test test case does not run when the whole suite is run with MiniTest. These issues still need investigation.
+* Fixed some acceptance tests to run in Ruby 1.9.2 - it's no longer possible to subvert the protection of a method by calling it via Object#send.
+* Fixed "test:performance" rake task so it runs in Ruby 1.9.2.
+* Fix test incorrectly failing under Rubinius 1.0. This test imposed too many constraints. It appears that Object#inspect legitimately calls Object#object_id in Rubinius. But we're only interested in what 'id' methods Mocha::ObjectMethods#mocha_inspect calls. By stubbing Object#inspect we can relax the constraints imposed by the test.
+* Luke Redpath (lukeredpath) added new shorthand "any" and "all" composite parameter matchers using "&" and "|". This provides an alternative syntax for expecting any or all matchers to pass, e.g. foo.expects(:bar).with(equals(1) | equals(2)).
+* Improved documentation for Expectation#raises. A number of people have suggested an extension to the API to cope with custom exceptions that have extra constructor parameters. However, since the arguments supplied to Expectation#raises are just passed on to Kernel#raise, it's possible to pass in an instance of an exception. Thus no change to the API is required, but it does seem worthwhile pointing this out in the docs.
+* Corrected RDoc example for Expectation#never thanks to Red David (reddavis).
+* Improved RDoc including a change suggested by Rohit Arondekar (rohit).
+* Updated gemspec as requested by Sam Woodard (shwoodard).
+
+## 0.9.8
+* Fixed bug "NameError raised when using Mocha as a Rails plug-in" - http://floehopper.lighthouseapp.com/projects/22289/tickets/53. Since 0.9.6 the Rails plugin has been broken. See bug report for details. You will need to explicitly load Mocha *after* the test framework has been loaded, e.g. by adding "require 'mocha'" at the bottom of test/test_helper.rb.
+* Make Mocha::ParameterMatchers#regexp_matches, #includes, #has_value, #has_key more robust. Thanks to Sander Hartlage.
+* Allow passing a block to Mocha::Configuration methods to only change configuration for the duration of the block. Thanks to Dan Manges.
+* Fixed bug "doc generation fails in 0.9.7 gem" - http://floehopper.lighthouseapp.com/projects/22289/tickets/51.
+* Remove rdoc template incorporating google analytics from source control. The file just needs to exist locally and be ignored by source control. This should stop the warning showing up on e.g. RunCodeRun build results.
+
+## 0.9.7
+* Although I had provided a deprecation warning for people using Mocha::Standalone, I had assumed people wouldn't be explicitly loading the mocha/standalone.rb file. It turns out this assumption was incorrect at least in the case of Rspec. This is now fixed.
+
+## 0.9.6
+* Version 2.0.1 of the test-unit gem introduced a private 'run_test' method on TestCase which clashed with the public TestRunner#run_test method. So this latter method has been renamed to 'run_as_test'.
+* Stop requiring rubygems - this should be an environmental choice for the user. http://gist.github.com/54177 - describes why requiring rubygems in your library code is a bad idea.
+* It seems like overkill to vendorize coderay and meta_project when they're only needed to generate the examples for documentation and for publishing files on RubyForge. So I'm removing them and installing them locally as gems when I need them.
+* Added support for 'test-unit' gem (version >= 2.0). Note that as with other versions of Test::Unit I'm completely replacing the TestCase#run method. Unfortunately in version 2.0.0 this method differs slightly from the same method in version 2.0.1 & 2.0.2, so we have to provide different implementations to ensure that the internal working of Test::Unit are not compromised by Mocha. Note also that unless the 'test-unit' gem is loaded, requiring 'test/unit' leads to a mixture of stdlib and gem classes being loaded causing errors. To avoid a dependency on rubygems, the gem is loaded only if MOCHA_OPTIONS is set to 'use_test_unit_gem' - this option is only intended for use in running Mocha's own tests. It might be worthwhile to create a shim gem like minitest_tu_shim to allow the test-unit gem to completely replace the stdlib, but that's a job for another day. The changes in the Rakefile are to make the default task run with the 'test-unit' gem (version >= 2.0).
+* Renamed Mocha::Standalone to Mocha::API to better reflect its purpose. Added a deprecation warning for those who are referencing Mocha::Standalone.
+* Fix exception raised by HasEntry#matches? if first param is not a Hash (thanks to Taylor Barstow).
+* Ken Collins reported [1] that Mocha is always loading MiniTest if it is available and loading it causes some Rails/ActionPack tests to break. I've removed the loading of MiniTest, but this now means the user has to ensure that if they want to use MiniTest in conjunction with Mocha, he must load MiniTest before loading Mocha. [1] http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/2060
+* Implemented Bacon integration (thanks to Ubiratan Pires Alberton), but this was then removed after deciding only to maintain integration with Test::Unit and MiniTest which are both Ruby standard libraries. See mailing list for details.
+* Don't monkey-patch MiniTest if it's already been monkey-patched by Mocha.
+* Fixed bug: MiniTest integration was counting ExpectationErrors as errors not failures. http://floehopper.lighthouseapp.com/projects/22289-mocha/tickets/41.
+* Fixed bug: Some Bacon tests were failing in Ruby 1.9.1. http://floehopper.lighthouseapp.com/projects/22289-mocha/tickets/43.
+* Chad Humphries pointed out that in Ruby 1.9.1, if you are not using Test::Unit or MiniTest, Mocha will attempt to load and monkey-patch Test::Unit. Mocha will now only monkey-patch Test::Unit and/or MiniTest if they have already been loaded. MiniTest tests will now run in both Ruby 1.8.6 (with MiniTest gem) and in Ruby 1.9.1 (with MiniTest std lib). See Ligthouse ticket - http://floehopper.lighthouseapp.com/projects/22289/tickets/49.
+* Made Mocha compatible with minitest 1.4.0 and above (thanks to Denis Defreyne).
+
+## 0.9.5
+* Fixed Lighthouse bug #32 - stub_everything should mean mock responds to anything.
+* Added Expectation#twice to improve readability. Thanks to pull request from Celestino Gomes.
+* In Ruby 1.9.1, requiring 'test/unit' loads a thin wrapper around MiniTest and Test::Unit::TestCase ends up inheriting from MiniTest::Unit::TestCase. So we need to avoid including the Mocha modules more than once to avoid nasty consequences. Thanks to Matthias Hennemeyer for help with this.
+* Ruby 1.9 includes rake, but not rake/contrib. For the moment I've moved the sshpublisher require into the only rake task that needs it, so that I can at least run the tests in Ruby 1.9. It looks like I will need to build a rake/contrib gem or similar to get this working properly - http://intertwingly.net/blog/2008/01/07/Rake-Contrib-for-1-9
+
+## 0.9.4
+* Added mocha.gemspec file generated with Chad Woolley's new rake task, so that a floehopper-mocha gem will get built on GitHub.
+* Add rake task to update mocha.gemspec with unique version, which will cause gem to be auto-built on github
+* As Tobias Crawley correctly pointed out in feature request #23055 "stubs(with_hash) not working with existing object" [1], following the principle of least surprise, it should be possible to call ObjectMethods#expects & ObjectMethods#stubs with a Hash of method_names vs return_values like you can with Mock#expects & Mock#stubs. I've also updated & improved the docs to reflect the changes. [1] http://rubyforge.org/tracker/index.php?func=detail&aid=23055&group_id=1917&atid=7480
+* Removed deprecated gem autorequire.
+
+## 0.9.3
+* Added support for MiniTest thanks to Jeff Smick.
+* Fixed a possible bug with some of the non-default Configuration options relating to the argument to Object#respond_to?
+* As per Jay Fields recommendations [1] and with further impetus from a talk at Ruby Manor, any methods added to core classes are now added by including a module. This means that Mocha is a better citizen of the Ruby world and it's behaviour is more easily extended. [1] http://blog.jayfields.com/2008/07/ruby-underuse-of-modules.html & http://blog.jayfields.com/2008/07/ruby-redefine-method-behavior.html
+* Removed deprecated gem autorequire.
+
+## 0.9.2
+* Improved documentation to address [#22530] 'Mock methods with multiple return values not possible?'
+* respond_with parameter matcher was not available in tests.
+* Patch [#22630] Fix for a bug in running Rails tests with Ruby 1.8.7. Array#flatten was being called which in turn was checking whether each element responded to #to_ary. This check was using the two parameter version of #respond_to?, but Mock was only defining a one parameter version.
+
+## 0.9.1
+
+* Fixed bug #21465 - expects & stubs should support method names as strings (as well as symbols) or fail fast. Convert all expectation method names to a symbol in case they were supplied as a string.
+* By removing Mock#unexpected_method_called we reduce the number of methods vulnerable to the problem that surfaced in bug #21563.
+* Fix bug #21563 - stubbing 'verified?' method is unsafe. Instance method names on the Mock class should be more obscure.
+* Performance improvement. StubbaExampleTest goes twice as fast on my local machine.
+* Added primitive performance test to default rake task.
+* Fix format of case statements which don't work in Ruby 1.9 and make others consistent.
+* There is no point in running (potentially expensive) checks if configuration is set to allow such checks to fail. This is a relatively quick fix in response to Chris McGrath's performance problems.
+* Fix for bug #21161 - 'uninitialized constant Deprecation in stubba.rb'.
+* It's more readable to talk about 'once' and 'twice' rather than '1 time' and '2 times'.
+* Fix bug #20883 - never should raise when called to prevent follow up errors. Fail fast when there are no matching invokable expectations and handle the stub_everything case sensibly. This might not be entirely backwards compatible, but I think the benefits outweigh the risks. The most likely change is that a test that was already failing will now fail faster, which doesn't seem so awful.
+
+## 0.9.0
+
+* Configurable warnings or errors
+  * when a method on a non-public method is stubbed
+  * when a method on a non-existent method is stubbed
+  * when a method on a non-mock object is stubbed
+  * when a method is stubbed unnecessarily (i.e. the stubbed method is not called during the test)
+
+* Improved error messages
+  * User-friendly list of unsatisfied expectations, satisfied expectations and state machines.
+  * Improved readability of cardinality description.
+  * Display sensible failure message for any_instance expectations e.g. "#<AnyInstance:Foo>.bar - expected calls: 1, actual calls: 0"
+
+* Parameter matchers
+  * New to this release
+    * optionally (allows matching of optional parameters if available)
+    * yaml_equivalent (allows matching of YAML that represents the specified object)
+    * responds_with (tests the quack not the duck)
+  * Nesting of parameter matchers is now supported.
+
+* Optional block passed into mock initializer is evaluated in the context of the new mock instance and can be used as a shortcut to set up expectations.
+
+* Added JMock-style sequences for constraining the order of expected invocations. See Standalone#sequence and Expectation#in_sequence.
+
+* Added JMock-style states for constraining the order of expected invocations. See Standalone#states, Expectation#then, Expectation#when and StateMachine.
+
+* Compatibility with versions of Ruby
+  * Compatibility with Ruby v1.9. All test errors and warnings fixed.
+  * Nasty fix so that TestCaseAdaptor works consistently with earlier versions of Test::Unit as well as more recent versions.
+  * Added platform to gem specification to avoid bug in rubygems 0.9.5 - see http://www.dcmanges.com/blog/rubygems-0-9-5-platform-bug and http://rubygems.org/read/chapter/20#platform.
+  * Make ExpectationRaiser deal with subclasses of Interrupt which seem to need a message supplied in the raise statement in Ruby 1.8.6 (but not 1.8.4 or 1.9). Not sure this is really Mocha's responsibility.
+
+* Added deprecation warning in stubba.rb which is no longer needed and will be removed.
+
+* Supply positioning information to evals to improve any error messages. See http://ola-bini.blogspot.com/2008/01/ruby-antipattern-using-eval-without.html

+
+## 0.5.5
+
+- Renamed Matches parameter matcher to RegexpMatches for clarity.
+- Added noframes tag to rdoc index to assist Google.
+
+## 0.5.4
+
+- Added matches parameter matcher for matching regular expressions.
+
+## 0.5.3
+
+- Attempt to fix packaging problems by switching to newer version (1.15.1) of gnutar and setting COPY_EXTENDED_ATTRIBUTES_DISABLE environment variable.
+- Removed unused ExpectationSequenceError exception.
+- Added instance_of and kind_of parameter matchers.
+- Added Google Webmaster meta tag to rdoc template header.
+- Put Google Webmaster meta tag in the right header i.e. the one for the index page.
+
+## 0.5.2
+
+- Fix bug 11885 - "never doesn't work with stub_everything" submitted by Alexander Lang. In fixing this bug, also fixed undiscoverd bug where expected & actual invocation counts were being incorrectly reported which seems to have been introduced when fixes were added for invocation dispatch (see MockedMethodDispatchAcceptanceTest).
+- Previously when an expectation did not allow more invocations, it was treated as not matching. Now we prefer matching expectations which allow more invocations, but still match expectations which cannot allow more invocations. I think this may be overcomplicating things, but let's see how it goes.
+
+## 0.5.1
+
+- Fixed bug #11583 "Mocha 0.5.0 throwing unexpected warnings". Also switched on ruby warning for all rake test tasks. Fixed majority of warnings, but some left to fix.
+
+## 0.5.0
+
+- Parameter Matchers - I’ve added a few Hamcrest-style parameter matchers which are designed to be used inside Expectation#with. The following matchers are currently available: anything(), includes(), has_key(), has_value(), has_entry(), all_of() & any_of(). More to follow soon. The idea is eventually to get rid of the nasty parameter_block option on Expectation#with.
+
+  object = mock()
+  object.expects(:method).with(has_key('key_1'))
+  object.method('key_1' => 1, 'key_2' => 2)
+  # no verification error raised
+
+  object = mock()
+  object.expects(:method).with(has_key('key_1'))
+  object.method('key_2' => 2)
+  # verification error raised, because method was not called with Hash containing key: 'key_1'
+
+- Values Returned and Exceptions Raised on Consecutive Invocations - Allow multiple calls to Expectation#returns and Expectation#raises to build up a sequence of responses to invocations on the mock. Added syntactic sugar method Expectation#then to allow more readable expectations.
+
+  object = mock()
+  object.stubs(:method).returns(1, 2).then.raises(Exception).then.returns(4)
+  object.method # => 1
+  object.method # => 2
+  object.method # => raises exception of class Exception
+  object.method # => 4
+
+- Yields on Consecutive Invocations - Allow multiple calls to yields on single expectation to allow yield parameters to be specified for consecutive invocations.
+
+  object = mock()
+  object.stubs(:method).yields(1, 2).then.yields(3)
+  object.method { |*values| p values } # => [1, 2]
+  object.method { |*values| p values } # => [3]
+
+- Multiple Yields on Single Invocation - Added Expectation#multiple_yields to allow a mocked or stubbed method to yield multiple times for a single invocation.
+
+  object = mock()
+  object.stubs(:method).multiple_yields([1, 2], [3])
+  object.method { |*values| p values } # => [1, 2] # => [3]
+
+- Invocation Dispatch - Expectations were already being matched in reverse order i.e. the most recently defined one was being found first. This is still the case, but we now stop matching an expectation when its maximum number of expected invocations is reached. c.f. JMock v1. A stub will never stop matching by default. Hopefully this means we can soon get rid of the need to pass a Proc to Expectation#returns.
+
+  object = mock()
+  object.stubs(:method).returns(2)
+  object.expects(:method).once.returns(1)
+  object.method # => 1
+  object.method # => 2
+  object.method # => 2
+  # no verification error raised
+
+  # The following should still work...
+
+  Time.stubs(:now).returns(Time.parse('Mon Jan 01 00:00:00 UTC 2007'))
+  Time.now # => Mon Jan 01 00:00:00 UTC 2007
+  Time.stubs(:now).returns(Time.parse('Thu Feb 01 00:00:00 UTC 2007'))
+  Time.now # => Thu Feb 01 00:00:00 UTC 2007
+
+- Deprecate passing an instance of Proc to Expectation#returns.
+- Explicitly include all Rakefile dependencies in project.
+- Fixed old Stubba example.
+- Fix so that it is possible for a stubbed method to raise an Interrupt exception without a message in Ruby 1.8.6
+- Added responds_like and quacks_like.
+- Capture standard object methods before Mocha adds any.
+- Added Expectation#once method to make interface less surprising.
+- Use Rake::TestTask to run tests. Created three separate tasks to run unit, integration & acceptance tests. Split inspect_test into one file per TestCase. Deleted superfluous all_tests file.
+- Fiddled with mocha_inspect and tests to give more sensible results on x86 platform.
+- Fixed bug #7834 "infinite_range.rb makes incorrect assumption about to_f" logged by James Moore.
+
+## 0.4.0
+
+- Allow naming of mocks (patch from Chris Roos).
+- Specify multiple return values for consecutive calls.
+- Improved consistency of expectation error messages.
+- Allow mocking of Object instance methods e.g. kind_of?, type.
+- Provide aliased versions of #expects and #stubs to allow mocking of these methods.
+- Added at_least, at_most, at_most_once methods to expectation.
+- Allow expects and stubs to take a hash of method and return values.
+- Eliminate warning: "instance variable @yield not initialized" (patch from Xavier Shay).
+- Restore instance methods on partial mocks (patch from Chris Roos).
+- Allow stubbing of a method with non-word characters in its name (patch from Paul Battley).
+- Removed coupling to Test::Unit.
+- Allow specified exception instance to be raised (patch from Chris Roos).
+- Make mock object_id appear in hex like normal Ruby inspect (patch from Paul Battley).
+- Fix path to object.rb in rdoc rake task (patch from Tomas Pospisek).
+- Reverse order in which expectations are matched, so that last expectation is matched first. This allows e.g. a call to #stubs to be effectively overridden by a call to #expects (patch from Tobias Lutke).
+- Stubba & SmartTestCase modules incorporated into Mocha module so only need to require 'mocha' - no longer need to require 'stubba'.
+- AutoMocha removed.
+
+## 0.3.3
+
+- Quick bug fix to restore instance methods on partial mocks (for Kevin Clark).
+
+## 0.3.2
+
+- Examples added.
+
+## 0.3.1
+
+- Dual licensing with MIT license added.
+
+## 0.3.0
+
+* Rails plugin.
+* Auto-verify for expectations on concrete classes.
+* Include each expectation verification in the test result assertion count.
+* Filter out noise from assertion backtraces.
+* Point assertion backtrace to line where failing expectation was created.
+* New yields method for expectations.
+* Create stubs which stub all method calls.
+* Mocks now respond_to? expected methods.
+
+## 0.2.1
+
+* Rename MochaAcceptanceTest::Rover#move method to avoid conflict with Rake (in Ruby 1.8.4 only?)
+
+## 0.2.0
+
+* Small change to SetupAndTeardown#teardown_stubs suggested by Luke Redpath (http://www.lukeredpath.co.uk) to allow use of Stubba with RSpec (http://rspec.rubyforge.org).
+* Reorganized directory structure and extracted addition of setup and teardown methods into SmartTestCase mini-library.
+* Addition of auto-verify for Mocha (but not Stubba). This means there is more significance in the choice of expects or stubs in that any expects on a mock will automatically get verified.
+
+So instead of...
+
+  wotsit = Mocha.new
+  wotsit.expects(:thingummy).with(5).returns(10)
+  doobrey = Doobrey.new(wotsit)
+  doobrey.hoojamaflip
+  wotsit.verify
+
+you need to do...
+
+  wotsit = mock()
+  wotsit.expects(:thingummy).with(5).returns(10)
+  doobrey = Doobrey.new(wotsit)
+  doobrey.hoojamaflip
+  # no need to verify
+
+There are also shortcuts as follows...
+
+instead of...
+
+  wotsit = Mocha.new
+  wotsit.expects(:thingummy).returns(10)
+  wotsit.expects(:summat).returns(25)
+
+you can have...
+
+  wotsit = mock(:thingummy => 5, :summat => 25)
+
+and instead of...
+
+  wotsit = Mocha.new
+  wotsit.stubs(:thingummy).returns(10)
+  wotsit.stubs(:summat).returns(25)
+
+you can have...
+
+  wotsit = stub(:thingummy => 5, :summat => 25)
+
+## 0.1.2
+
+* Minor tweaks
+
+## 0.1.1
+
+* Initial release.

+
+  # Traditional mock object.
+  #
+  # All methods return an {Expectation} which can be further modified by
+  # methods on {Expectation}.
+  #
+  # Stubs and expectations are basically the same thing. A stub is just an
+  # expectation of zero or more invocations. The {#stubs} method is syntactic
+  # sugar to make the intent of the test more explicit.
+  #
+  # When a method is invoked on a mock object, the mock object searches through
+  # its expectations from newest to oldest to find one that matches the
+  # invocation. After the invocation, the matching expectation might stop
+  # matching further invocations. For example, an +expects(:foo).once+
+  # expectation only matches once and will be ignored on future invocations
+  # while an +expects(:foo).at_least_once+ expectation will always be matched
+  # against invocations.
+  #
+  # This scheme allows you to:
+  #
+  # - Set up default stubs in your the +setup+ method of your test class and
+  #   override some of those stubs in individual tests.
+  # - Set up different +once+ expectations for the same method with different
+  #   action per invocation. However, it's better to use the
+  #   {Expectation#returns} method with multiple arguments to do this, as
+  #   described below.
+  #
+  # However, there are some possible "gotchas" caused by this scheme:
+  #
+  # - if you create an expectation and then a stub for the same method, the
+  #   stub will always override the expectation and the expectation will never
+  #   be met.
+  # - if you create a stub and then an expectation for the same method, the
+  #   expectation will match, and when it stops matching the stub will be used
+  #   instead, possibly masking test failures.
+  # - if you create different expectations for the same method, they will be
+  #   invoked in the opposite order than that in which they were specified,
+  #   rather than the same order.
+  #
+  # The best thing to do is not set up multiple expectations and stubs for the
+  # same method with exactly the same matchers. Instead, use the
+  # {Expectation#returns} method with multiple arguments to create multiple
+  # actions for a method. You can also chain multiple calls to
+  # {Expectation#returns} and {Expectation#raises} (along with syntactic sugar
+  # {Expectation#then} if desired).
+  #
+  # @example
+  #   object = mock()
+  #   object.stubs(:expected_method).returns(1, 2).then.raises(Exception)
+  #   object.expected_method # => 1
+  #   object.expected_method # => 2
+  #   object.expected_method # => raises exception of class Exception1
+  #
+  # If you want to specify more complex ordering or order invocations across
+  # different mock objects, use the {Expectation#in_sequence} method to
+  # explicitly define a total or partial ordering of invocations.
+  class Mock

+
+Lots of Ruby libraries parse JSON and everyone has their favorite JSON coder.
+Instead of choosing a single JSON coder and forcing users of your library to be
+stuck with it, you can use MultiJSON instead, which will simply choose the
+fastest available JSON coder. Here's how to use it:
+
+```ruby
+require 'multi_json'
+
+MultiJson.load('{"abc":"def"}') #=> {"abc" => "def"}
+MultiJson.load('{"abc":"def"}', :symbolize_keys => true) #=> {:abc => "def"}
+MultiJson.dump({:abc => 'def'}) # convert Ruby back to JSON
+MultiJson.dump({:abc => 'def'}, :pretty => true) # encoded in a pretty form (if supported by the coder)
+```
+
+When loading invalid JSON, MultiJson will throw a `MultiJson::ParseError`. `MultiJson::DecodeError` and `MultiJson::LoadError` are aliases for backwards compatibility.
+
+```ruby
+begin
+  MultiJson.load('{invalid json}')
+rescue MultiJson::ParseError => exception
+  exception.data # => "{invalid json}"
+  exception.cause # => JSON::ParserError: 795: unexpected token at '{invalid json}'
+end
+```
+
+`ParseError` instance has `cause` reader which contains the original exception.
+It also has `data` reader with the input that caused the problem.
+
+The `use` method, which sets the MultiJson adapter, takes either a symbol or a
+class (to allow for custom JSON parsers) that responds to both `.load` and `.dump`
+at the class level.
+
+When MultiJson fails to load the specified adapter, it'll throw `MultiJson::AdapterError`
+which inherits from `ArgumentError`.
+
+MultiJSON tries to have intelligent defaulting. That is, if you have any of the
+supported engines already loaded, it will utilize them before attempting to
+load any. When loading, libraries are ordered by speed. First Oj, then Yajl,
+then the JSON gem, then JSON pure. If no other JSON library is available,
+MultiJSON falls back to [OkJson][], a simple, vendorable JSON parser.
+
+[okjson]: https://github.com/kr/okjson
+
+## Supported JSON Engines
+
+* [Oj](https://github.com/ohler55/oj) Optimized JSON by Peter Ohler
+* [Yajl](https://github.com/brianmario/yajl-ruby) Yet Another JSON Library by Brian Lopez
+* [JSON](https://github.com/flori/json) The default JSON gem with C-extensions (ships with Ruby 1.9)
+* [JSON Pure](https://github.com/flori/json) A Ruby variant of the JSON gem
+* [NSJSONSerialization](https://developer.apple.com/library/ios/#documentation/Foundation/Reference/NSJSONSerialization_Class/Reference/Reference.html) Wrapper for Apple's NSJSONSerialization in the Cocoa Framework (MacRuby only)
+* [gson.rb](https://github.com/avsej/gson.rb) A Ruby wrapper for google-gson library (JRuby only)
+* [JrJackson](https://github.com/guyboertje/jrjackson) JRuby wrapper for Jackson (JRuby only)
+* [OkJson][okjson] A simple, vendorable JSON parser
+
+## Supported Ruby Versions
+This library aims to support and is [tested against][travis] the following Ruby
+implementations:
+
+* Ruby 1.8.7
+* Ruby 1.9.2
+* Ruby 1.9.3
+* Ruby 2.0.0
+* Ruby 2.1.0
+* Ruby 2.1.1
+* [JRuby][]
+* [Rubinius][]
+* [MacRuby][] (not tested on Travis CI)
+
+[jruby]: http://www.jruby.org/
+[rubinius]: http://rubini.us/
+[macruby]: http://www.macruby.org/
+
+If something doesn't work on one of these interpreters, it's a bug.
+
+This library may inadvertently work (or seem to work) on other Ruby
+implementations, however support will only be provided for the versions listed
+above.
+
+If you would like this library to support another Ruby version, you may
+volunteer to be a maintainer. Being a maintainer entails making sure all tests
+run and pass on that implementation. When something breaks on your
+implementation, you will be responsible for providing patches in a timely
+fashion. If critical issues for a particular implementation exist at the time
+of a major release, support for that Ruby version may be dropped.
+
+## Versioning
+
+This library aims to adhere to [Semantic Versioning 2.0.0][semver]. Violations
+of this scheme should be reported as bugs. Specifically, if a minor or patch
+version is released that breaks backward compatibility, that version should be
+immediately yanked and/or a new version should be immediately released that
+restores compatibility. Breaking changes to the public API will only be
+introduced with new major versions. As a result of this policy, you can (and
+should) specify a dependency on this gem using the [Pessimistic Version
+Constraint][pvc] with two digits of precision. For example:
+
+```ruby
+spec.add_dependency 'multi_json', '~> 1.0'
+```

+# Ruby/NArray
+
+* ver 0.6.1.0 (2014-06-02)
+* [Home page](http://masa16.github.io/narray/index.ja.html)
+* [GitHub Repository](https://github.com/masa16/narray)
+* [RubyGems](https://rubygems.org/gems/narray)
+* [NArrayメソッド一覧](https://github.com/masa16/narray/blob/master/SPEC.ja.txt)
+
+## Ruby/NArrayの特徴:
+
+* Rubyで、高速な数値計算が可能。
+* 要素には、8,16,32 bit 整数、単精度/倍精度の実数/複素数、
+  および Rubyオブジェクトをサポート。
+* 部分配列の取出し、代入も容易。
+  要素位置の指定には、数値、範囲、インデックスの配列が使用可能。
+* +, -, *, /, %, ** や 算術関数の演算は、要素-対-要素でおこなう。
+* NMath 算術関数モジュール
+* 配列同士の演算・代入は、各次元のサイズが同じであることが必要。
+  ただし、サイズが1の次元は、他方の配列のサイズに合わせて
+  「繰り返し」同じ要素が適用される。
+* FFTW (高速フーリエ変換) version 3 は次のモジュールでサポート。
+* Ruby/PGPLOT (グラフィックスライブラリ、別悃) にて
+  XYグラフ、ヒストグラム、等高線、イメージ表示可能。
+* 数値計算・画像処理・データ解析など幅広い応用が可能(と思う)。
+
+* 類似品
+  * Python/NumPy, Perl/PDL, Yorick, IDL
+
+* 不十分な点
+  * メソッドが不足。
+  * バグ出しが不十分。
+  * ドキュメントがない。
+
+## インストール方法
+
+Rubyの標準的な拡張ライブラリと同じです。ソースを展開したディレクトリで、
+
+    ruby extconf.rb
+    make
+    make install
+
+と実行します。
+
+## 動作確認
+
+* ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux]
+* gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC)

+	Ruby/NArray  ver 0.6.0.7 (2013-02-01)	by Masahiro TANAKA
+
+
+Class method:
+    NArray.new(typecode, size, ...)	create new NArray. initialize with 0.
+
+    NArray.byte(size,...)		1 byte unsigned integer
+    NArray.sint(size,...)		2 byte signed integer
+    NArray.int(size,...)		4 byte signed integer
+    NArray.sfloat(size,...)		single precision float
+    NArray.float(size,...)		double precision float
+    NArray.scomplex(size,...)		single precision complex
+    NArray.complex(size,...)		double precision complex
+    NArray.object(size,...)		Ruby object
+				all above method initialize with 0 or nil.
+
+    NArray.to_na(array)			convert to NArray
+    NArray.to_na(string,type[,size,...])
+    NArray[...]
+      NArray[1,5,10.0]  #=>  NArray.float(3):[1.0, 5.0, 10.0]
+      NArray[1..10]     #=>  NArray.int(10):[1,2,3,4,5,6,7,8,9,10]
+
+
+Class constant:
+    CLASS_DIMENSION	# of dimension treated as data.
+			0 for NArray, 1 for NVector, 2 for NMatrix.
+
+NArray information
+    self.dim		Return the dimension = the number of indices
+    self.rank		same as dim
+    self.shape		Return the array of sizes of each index
+    self.total		Return the number of total elements
+
+Slicing Array
+ - Index components:	Integer, Range, Array, true.
+ - Index order:		FORTRAN type.
+    a[ 1, 2, -1 ]	element slicing.
+			  If negative, counts backward from the end.
+			  Element-dimensions are contracted.
+    a[ 0..3, 4..1 ]	extract in the range.
+			  If the former of the range is bigger,
+			   return elements in reversed order.
+    a[ [1,3,2,4] ]	an array with the elements of the indices.
+			  If `a' has multi-dimension but, in [],
+			   single index is specified,
+			   `a' is treated as a single dimension array.
+    a[ 1, 2..3, [1,3,2,4], true ]   compound index.
+				    This returns 3-dim array.
+    a[]			same as a.dup.
+    a[ 0, true ]	sams as a[0,0..-1]. `true' means all.
+    a[ false, 0 ]	same as a[true,true,0], if a is a 3-d array,
+			`false' means ellipsis dimension.
+    a[ mask ]		masking. "mask" is a byte NArray with its
+			length equal to that of "a". According to the
+			value of each element of mask, the corresponding
+			element in "a" is eliminated (when 0) or
+			retained (when not 0).
+			Example:
+				a=NArray.float(2,2).indgen!
+				p a[ a.lt 3 ]
+				--> [ 0.0, 1.0, 2.0 ]
+				(Here, a.lt 3 gives a byte NArray)
+				(This is also done by a[ (a.lt 3).where ])
+
+ - A 2-or-more-dim array object with only one argument in `[ ]',
+   is treated as a flat 1-d array.
+   e.g.: a[3] is same as a[0,1] if a is 3x3 array.
+
+ - self.slice(...)	Same as self[...] but keeps the rank of
+			original array by not elimiting dimensions
+			whose length became equal to 1 (which self[]
+			does). This is not the case with the
+			1-dimensional indexing and masking (same as []).
+
+Replacing Elements -- Same rule as slicing
+
+    a[ 1, 2, 3 ] = 1
+    a[ 0..3, 1..4, 2..5 ] = 2
+    a[ [1,3,2,4], true ] = 3
+    a[] = 4			Same as a.fill!(4)
+
+    a[0..2]  = b[1..5]		--> Error! due to different num of elements.
+    a[1,2]   = b[0..2,1..3]	Storing elements from index [1,2]
+				( a[1,2]=b[0,1],a[2,2]=b[1,1],... )
+    a[0..2,0..3]  = b[0..2,1]	Storing repetitively
+				( a[0,0]=b[0,1],..,a[0,3]=b[0,1] )
+
+Delete row/columns -- Complement of slice
+
+    self.delete_at(...)	  Arguments are the same as the [] and slice methods
+			  see https://github.com/masa16/narray/issues/5
+
+Filling values
+    self.indgen!([start[,step]]) Generate index;
+				 Set values from 'start' with 'step' increment
+    self.fill!(value)		 Fill elements with 'value'
+    self.random!(max)		 Set random values between 0<=x<max
+				 using MT19337
+    self.randomn		 Set Normally distributed random values
+				 with mean=0, dispersion=1 (Box-Muller)
+    NArray.srand([seed])	 Set random seed.
+				 A time-depend seed is choosed if omitted.
+
+Operation: performed element by element
+    a = NArray.float(3,3).indgen
+    b = NArray.float(3,3).fill(10)
+    c = a*b	# --> NArray.float(3,3)
+
+    a = NArray.float(3,1).indgen
+    b = NArray.float(1,3).fill(10)
+    c = a*b	# --> NArray.float(3,3) -- size=1 dimension is extensible.

+This is based on trimmed version of MT19937.  To get the original version,

+
+The original copyright notice follows.
+
+   A C-program for MT19937, with initialization improved 2002/2/10.
+   Coded by Takuji Nishimura and Makoto Matsumoto.
+   This is a faster version by taking Shawn Cokus's optimization,
+   Matthe Bellew's simplification, Isaku Wada's real version.
+
+   Before using, initialize the state by using init_genrand(seed)
+   or init_by_array(init_key, key_length).

+Contributing to Parser
+----------------------
+
+Parser uses [Semantic Versioning](http://semver.org). Additionally, Parser employs a script to extract information from VCS (git) log and form a Changelog file. Thus, each commit which affects the public API in any way must be marked with one of the following sigils, or characters at the beginning of line:
+
+ * `-` for bugfixes. For example: `- lexer.rl: fixed lexing of "alias $foo $bar".`
+ * `+` for features. For example: `+ Implemented Parser::Rewriter, a module for non-intrusive rewriting of source code.`
+ * `*` for miscellaneous changes. For example: `* Converted measurement units from metric to imperial.`
+
+These categories map nicely to semantic versioning: `-` bugfixes increment patchlevel, `+` features increment minor version, `*` API changes increment major version.

+_Parser_ is a production-ready Ruby parser written in pure Ruby. It performs on
+par or better than Ripper, Melbourne, JRubyParser or ruby\_parser.
+
+You can also use [unparser](https://github.com/mbj/unparser) to produce
+equivalent source code from Parser's ASTs.
+
+Sponsored by [Evil Martians](http://evilmartians.com).
+
+## Installation
+
+    $ gem install parser
+
+## Usage
+
+Parse a chunk of code:
+
+    require 'parser/current'
+
+    p Parser::CurrentRuby.parse("2 + 2")
+    # (send
+    #   (int 2) :+
+    #   (int 2))
+
+Access the AST's source map:
+
+    p Parser::CurrentRuby.parse("2 + 2").loc
+    # #<Parser::Source::Map::Send:0x007fe5a1ac2388
+    #   @dot=nil,
+    #   @begin=nil,
+    #   @end=nil,
+    #   @selector=#<Source::Range (string) 2...3>,
+    #   @expression=#<Source::Range (string) 0...5>>
+
+    p Parser::CurrentRuby.parse("2 + 2").loc.selector.source
+    # "+"
+
+Traverse the AST: see the documentation for [gem ast](https://whitequark.github.io/ast/).
+
+Parse a chunk of code and display all diagnostics:
+
+    parser = Parser::CurrentRuby.new
+    parser.diagnostics.consumer = lambda do |diag|
+      puts diag.render
+    end
+
+    buffer = Parser::Source::Buffer.new('(string)')
+    buffer.source = "foo *bar"
+
+    p parser.parse(buffer)
+    # (string):1:5: warning: `*' interpreted as argument prefix
+    # foo *bar
+    #     ^
+    # (send nil :foo
+    #   (splat
+    #     (send nil :bar)))
+
+If you reuse the same parser object for multiple `#parse` runs, you need to
+`#reset` it.
+
+You can also use the `ruby-parse` utility (it's bundled with the gem) to play
+with Parser:
+
+    $ ruby-parse -L -e "2+2"
+    (send
+      (int 2) :+
+      (int 2))
+    2+2
+     ~ selector
+    ~~~ expression
+    (int 2)
+    2+2
+    ~ expression
+    (int 2)
+    2+2
+
+    $ ruby-parse -E -e "2+2"
+    2+2
+    ^ tINTEGER 2                                    expr_end     [0 <= cond] [0 <= cmdarg]
+    2+2
+     ^ tPLUS "+"                                    expr_beg     [0 <= cond] [0 <= cmdarg]
+    2+2
+      ^ tINTEGER 2                                  expr_end     [0 <= cond] [0 <= cmdarg]
+    2+2
+      ^ false "$eof"                                expr_end     [0 <= cond] [0 <= cmdarg]
+    (send
+      (int 2) :+
+      (int 2))
+
+## Features
+
+* Precise source location reporting.
+* [Documented](doc/AST_FORMAT.md) AST format which is convenient to work with.
+* A simple interface and a powerful, tweakable one.
+* Parses 1.8, 1.9, 2.0, 2.1 and 2.2 syntax with backwards-compatible
+  AST formats.
+* [Rewriting][rewriting] support.
+* Parsing error recovery.
+* Improved [clang-like][] diagnostic messages with location information.
+* Written in pure Ruby, runs on MRI 1.8.7 or >=1.9.2, JRuby and Rubinius in 1.8
+  and 1.9 mode.
+* Only one runtime dependency: the [ast][] gem.
+* [Insane][insane-lexer] Ruby lexer rewritten from scratch in Ragel.

+## Documentation
+
+Documentation for parser is available [online](https://whitequark.github.io/parser/).
+
+### Node names
+
+Several Parser nodes seem to be confusing enough to warrant a dedicated README section.
+
+#### (block)
+
+The `(block)` node passes a Ruby block, that is, a closure, to a method call represented by its first child, a `(send)`, `(super)` or `(zsuper)` node. To demonstrate:
+
+```
+$ ruby-parse -e 'foo { |x| x + 2 }'
+(block
+  (send nil :foo)
+  (args
+    (arg :x))
+  (send
+    (lvar :x) :+
+    (int 2)))
+```
+
+#### (begin) and (kwbegin)
+
+**TL;DR: Unless you perform rewriting, treat `(begin)` and `(kwbegin)` as the same node type.**
+
+Both `(begin)` and `(kwbegin)` nodes represent compound statements, that is, several expressions which are executed sequentally and the value of the last one is the value of entire compound statement. They may take several forms in the source code:
+
+  * `foo; bar`: without delimiters
+  * `(foo; bar)`: parenthesized
+  * `begin foo; bar; end`: grouped with `begin` keyword
+  * `def x; foo; bar; end`: grouped inside a method definition
+
+and so on.
+
+```
+$ ruby-parse -e '(foo; bar)'
+(begin
+  (send nil :foo)
+  (send nil :bar))
+$ ruby-parse -e 'def x; foo; bar end'
+(def :x
+  (args)
+  (begin
+    (send nil :foo)
+    (send nil :bar)))
+```
+
+Note that, despite its name, `kwbegin` node only has tangential relation to the `begin` keyword. Normally, Parser AST is semantic, that is, if two constructs look differently but behave identically, they get parsed to the same node. However, there exists a peculiar construct called post-loop in Ruby:
+
+```
+begin
+  body
+end while condition
+```
+
+This specific syntactic construct, that is, keyword `begin..end` block followed by a postfix `while`, [behaves][postloop] very unlike other similar constructs, e.g. `(body) while condition`. While the body itself is wrapped into a `while-post` node, Parser also supports rewriting, and in that context it is important to not accidentally convert one kind of loop into another.
+
+  [postloop]: http://rosettacode.org/wiki/Loops/Do-while#Ruby
+
+```
+$ ruby-parse -e 'begin foo end while cond'
+(while-post
+  (send nil :cond)
+  (kwbegin
+    (send nil :foo)))
+$ ruby-parse -e 'foo while cond'
+(while
+  (send nil :cond)
+  (send nil :foo))
+$ ruby-parse -e '(foo) while cond'
+(while
+  (send nil :cond)
+  (begin
+    (send nil :foo)))
+```
+
+(Parser also needs the `(kwbegin)` node type internally, and it is highly problematic to map it back to `(begin)`.)
+
+## Compatibility with Ruby MRI
+
+Unfortunately, Ruby MRI often changes syntax in patchlevel versions. This has happened, at least, for every release since 1.9; for example, commits [c5013452](https://github.com/ruby/ruby/commit/c501345218dc5fb0fae90d56a0c6fd19d38df5bb) and [04bb9d6b](https://github.com/ruby/ruby/commit/04bb9d6b75a55d4000700769eead5a5cb942c25b) were backported all the way from HEAD to 1.9. Moreover, there is no simple way to track these changes.
+
+This policy makes it all but impossible to make Parser precisely compatible with the Ruby MRI parser. Indeed, at September 2014, it would be necessary to maintain and update ten different parsers together with their lexer quirks in order to be able to emulate any given released Ruby MRI version.
+
+As a result, Parser chooses a different path: the `parser/rubyXY` parsers recognize the syntax of the latest minor version of Ruby MRI X.Y at the time of the gem release.
+
+## Known issues
+
+Adding support for the following Ruby MRI features in Parser would needlessly complicate it, and as they all are very specific and rarely occuring corner cases, this is not done.
+
+Parser has been extensively tested; in particular, it parses almost entire [Rubygems][rg] corpus. For every issue, a breakdown of affected gems is offered.
+
+ [rg]: https://rubygems.org
+
+### Void value expressions
+
+Ruby MRI prohibits so-called "void value expressions". For a description
+of what a void value expression is, see [this
+gist](https://gist.github.com/JoshCheek/5625007) and [this Parser
+issue](https://github.com/whitequark/parser/issues/72).
+
+It is unknown whether any gems are affected by this issue.
+
+### Invalid characters inside comments
+
+Ruby MRI permits arbitrary non-7-bit characters to appear in comments regardless of source encoding.
+
+As of 2013-07-25, there are about 180 affected gems.
+
+### \u escape in 1.8 mode
+
+Ruby MRI 1.8 permits to specify a bare `\u` escape sequence in a string; it treats it like `u`. Ruby MRI 1.9 and later treat `\u` as a prefix for Unicode escape sequence and do not allow it to appear bare. Parser follows 1.9+ behavior.
+
+As of 2013-07-25, affected gems are: activerdf, activerdf_net7, fastreader, gkellog-reddy.
+
+### Invalid Unicode escape sequences
+
+Ruby MRI 1.9+ permits to specify invalid Unicode codepoints in Unicode escape sequences, such as `\u{d800}`.
+
+As of 2013-07-25, affected gems are: aws_cloud_search.
+
+### Dollar-dash
+
+(This one is so obscure I couldn't even think of a saner name for this issue.) Pre-2.1 Ruby allows
+to specify a global variable named `$-`. Ruby 2.1 and later treat it as a syntax error. Parser
+follows 2.1 behavior.
+
+No known code is affected by this issue.

+# Customizing Parsers
+
+While the default setup of the parsers provided by this Gem should be suitable
+for most some developers might want to change parts of it. An example would be
+the use of a custom class for nodes instead of `Parser::AST::Node`.
+
+Customizing the AST is done by creating a custom builder class and passing it
+to the constructor method of a parser. The default setup comes down to the
+following:
+
+    builder = Parser::Builders::Default.new
+    parser  = Parser::Ruby19.new(builder)
+
+When creating your own builder class it's best to subclass the default one so
+that you don't have to redefine every used method again:
+
+    class MyBuilder < Parser::Builders::Default
+
+    end
+
+    builder = MyBuilder.new
+    parser  = Parser::Ruby19.new(builder)
+
+## Custom Node Classes
+
+To use a custom node class you have to override the method
+`Parser::Builders::Default#n`:
+
+    class MyBuilder < Parser::Builders::Default
+      def n(type, children, location)
+        return MyNodeClass.new(type, children, :location => location)
+      end
+    end
+
+Note that the used class (and corresponding instance) must be compatible with
+`Parser::AST::Node` so it's best to subclass it and override/add code where
+needed.

+Entry points
+------------
+
+Parser should be kept as slim as possible. This includes not loading
+any potentially large files when they are likely to be unused in practice.
+
+Parser has five main (classes of) `require` entry points:
+
+ * `require 'parser'`. Main entry point, requires all classes which
+   are used across the entire library.
+ * `require 'parser/rubyXX'`. Version-specific entry point. Can raise
+   a NotImplementedError if current Ruby runtime is unable to parse the
+   requested Ruby version.
+ * `require 'parser/all'`. Requires all available parsers for released
+   versions of Ruby. Can raise NotImplementedError.
+ * `require 'parser/runner'`. Requires all the stuff which is useful for
+   command-line tools but not otherwise.
+ * `require 'parser/runner/X'`. Runner-specific entry point.
+
+All non-main entry points internally `require 'parser'`. Additionally, all
+runner-specific entry points internally `requre 'parser/runner'`.

+# === BEFORE YOU START ===
+#
+# Read the Ruby Hacking Guide chapter 11, available in English at
+# http://whitequark.org/blog/2013/04/01/ruby-hacking-guide-ch-11-finite-state-lexer/
+#
+# Remember two things about Ragel scanners:
+#
+#   1) Longest match wins.
+#
+#   2) If two matches have the same length, the first
+#      in source code wins.
+#
+# General rules of making Ragel and Bison happy:
+#
+#  * `p` (position) and `@te` contain the index of the character
+#    they're pointing to ("current"), plus one. `@ts` contains the index
+#    of the corresponding character. The code for extracting matched token is:
+#
+#       @source[@ts... at te]
+#
+#  * If your input is `foooooooobar` and the rule is:
+#
+#       'f' 'o'+
+#
+#    the result will be:
+#
+#       foooooooobar
+#       ^ ts=0   ^ p=te=9
+#
+#  * A Ragel lexer action should not emit more than one token, unless
+#    you know what you are doing.
+#
+#  * All Ragel commands (fnext, fgoto, ...) end with a semicolon.
+#
+#  * If an action emits the token and transitions to another state, use
+#    these Ragel commands:
+#
+#       emit($whatever)
+#       fnext $next_state; fbreak;
+#
+#    If you perform `fgoto` in an action which does not emit a token nor
+#    rewinds the stream pointer, the parser's side-effectful,
+#    context-sensitive lookahead actions will break in a hard to detect
+#    and debug way.
+#
+#  * If an action does not emit a token:
+#
+#       fgoto $next_state;
+#
+#  * If an action features lookbehind, i.e. matches characters with the
+#    intent of passing them to another action:
+#
+#       p = @ts - 1
+#       fgoto $next_state;
+#
+#    or, if the lookbehind consists of a single character:
+#
+#       fhold; fgoto $next_state;
+#
+#  * Ragel merges actions. So, if you have `e_lparen = '(' %act` and
+#    `c_lparen = '('` and a lexer action `e_lparen | c_lparen`, the result
+#    _will_ invoke the action `act`.
+#
+#    e_something stands for "something with **e**mbedded action".
+#
+#  * EOF is explicit and is matched by `c_eof`. If you want to introspect
+#    the state of the lexer, add this rule to the state:
+#
+#       c_eof => do_eof;
+#
+#  * If you proceed past EOF, the lexer will complain:
+#
+#       NoMethodError: undefined method `ord' for nil:NilClass

+  # === STRING AND HEREDOC PARSING ===
+  #
+
+  # Heredoc parsing is quite a complex topic. First, consider that heredocs
+  # can be arbitrarily nested. For example:
+  #
+  #     puts <<CODE
+  #     the result is: #{<<RESULT.inspect
+  #       i am a heredoc
+  #     RESULT
+  #     }
+  #     CODE
+  #
+  # which, incidentally, evaluates to:
+  #
+  #     the result is: "  i am a heredoc\n"
+  #
+  # To parse them, lexer refers to two kinds (remember, nested heredocs)
+  # of positions in the input stream, namely @heredoc_e
+  # (HEREDOC declaration End) and @herebody_s (HEREdoc BODY line Start).
+  #
+  # @heredoc_e is simply contained inside the corresponding Literal, and
+  # when the heredoc is closed, the lexing is restarted from that position.
+  #
+  # @herebody_s is quite more complex. First, @herebody_s changes after each
+  # heredoc line is lexed. This way, at '\n' tok(@herebody_s, @te) always
+  # contains the current line, and also when a heredoc is started, @herebody_s
+  # contains the position from which the heredoc will be lexed.
+  #
+  # Second, as (insanity) there are nested heredocs, we need to maintain a
+  # stack of these positions. Each time #push_literal is called, it saves current
+  # @heredoc_s to literal.saved_herebody_s, and after an interpolation (possibly
+  # containing another heredocs) is closed, the previous value is restored.

+    # {Map} relates AST nodes to the source code they were parsed from.
+    # More specifically, a {Map} or its subclass contains a set of ranges:
+    #
+    #  * `expression`: smallest range which includes all source corresponding
+    #    to the node and all `expression` ranges of its children.
+    #  * other ranges (`begin`, `end`, `operator`, ...): node-specific ranges
+    #    pointing to various interesting tokens corresponding to the node.
+    #
+    # Note that the {Map::Heredoc} map is the only one whose `expression` does
+    # not include other ranges. It only covers the heredoc marker (`<<HERE`),
+    # not the here document itself.
+    #
+    # All ranges except `expression` are defined by {Map} subclasses.
+    #
+    # Ranges (except `expression`) can be `nil` if the corresponding token is
+    # not present in source. For example, a hash may not have opening/closing
+    # braces, and so would its source map.
+    #
+    #     p Parser::CurrentRuby.parse('[1 => 2]').children[0].loc
+    #     # => <Parser::Source::Map::Collection:0x007f5492b547d8
+    #     #  @end=nil, @begin=nil,
+    #     #  @expression=#<Source::Range (string) 1...7>>
+    #
+    # The {file:doc/AST_FORMAT.md} document describes how ranges associated to source
+    # code tokens. For example, the entry
+    #
+    #     (array (int 1) (int 2))
+    #
+    #     "[1, 2]"
+    #      ^ begin
+    #           ^ end
+    #      ~~~~~~ expression
+    #
+    # means that if `node` is an {Parser::AST::Node} `(array (int 1) (int 2))`,
+    # then `node.loc` responds to `begin`, `end` and `expression`, and
+    # `node.loc.begin` returns a range pointing at the opening bracket, and so on.
+    #
+    # If you want to write code polymorphic by the source map (i.e. accepting
+    # several subclasses of {Map}), use `respond_to?` instead of `is_a?` to
+    # check whether the map features the range you need. Concrete {Map}
+    # subclasses may not be preserved between versions, but their interfaces
+    # will be kept compatible.
+    #
+    # You can visualize the source maps with `ruby-parse -E` command-line tool.
+    #
+    # @example
+    #  require 'parser/current'
+    #
+    #  p Parser::CurrentRuby.parse('[1, 2]').loc

+  # Guidelines for test naming:
+  #  * Test structure follows structure of AST_FORMAT.md.
+  #  * Test names follow node names.
+  #  * Structurally similar sources may be grouped into one test.
+  #  * If, following the guidelines above, names clash, append
+  #    an abbreviated disambiguator. E.g. `test_class` and
+  #    `test_class_super`.
+  #  * When writing a test for a bug, append unabbreviated (but
+  #    concise) bug description. E.g. `test_class_bug_missing_newline`.
+  #  * Do not append Ruby language version to the name.
+  #  * When in doubt, look at existing test names.
+  #
+  # Guidelines for writing assertions:
+  #  * Don't check for structurally same source mapping information
+  #    more than once or twice in the entire file. It clutters the
+  #    source for no reason.
+  #  * Don't forget to check for optional delimiters. `()`, `then`, etc.
+  #  * When in doubt, look at existing assertions.

+= 2.0 / ?? (future release changes, like a reminder to self)
+  
+  - prsnt? and absnt? are now finally banned into oblivion. Wasting vocals for
+    the win. 
+
+= 1.6 / ??
+
+  + Parslet accelerators permit replacing parts of your parser with optimized
+    atoms using pattern matching. Look at examples/optimized_erb.rb or the
+    introduction to the feature in qed/accelerators.md.
+
+  + infix_expression permits to declare an infix expression parser (think 
+    calculator) directly. This will solve many of the problems we have 
+    more elegantly. 
+
+  - Drops 1.8.7 compatibility. 
+
+  ! A performance anomaly when parsing multibyte characters has been detected
+    and fixed with the help of Zach Moazeni (@zmoazeni).
+
+  ! A few small bug fixes and optimisations have been introduced. API should 
+    remain unchanged. 
+    
+= 1.5 / 27Dec2012
+    
+  + Handles unconsumed input at end of parse completely differently. Instead
+    of generating a toplevel error, it now raises an error in every branch
+    of the parse. More information in the resulting exception ensues! Thanks
+    again to John Mettraux for inspiration & acceptance specs. 
+    
+    NOTE that this means that the UnconsumedInput exception is gone, since the
+    unconsumed input case is nothing special anymore. 
+    
+  * This history now finally reads like the Changelog of the linux kernel. 
+    Meaning that probably no one ever reads this. 
+    
+  + Captures and parsing subsequent input based on captured values. This has
+    been long overdue - finally you can parse HEREdocs with parslet!
+    
+= 1.4.0 / 25May2012
+
+  + Revised documentation. A few new API features have finally made it into
+    the documentation. Examples in the documentation are now curated and
+    run against the current code so that they really really work. 
+    Also, the website generation tools have been replaced with 2012-style
+    tools. Much less pain to update now. 
+
+  + Parslet::Source now doesn't hold a StringIO, it directly holds the 
+    buffer to be parsed. The api of Source has changed a tiny bit. This change
+    has been made for speed optimisation reasons.
+
+  + :reporter argument to parse, allowing to customize error reporting within
+    wide boundaries. See issue #64 for a discussion. 
+    Included are two error reporters, one (default) with the existing error
+    tree functionality, one reporting deepest errors as defined by the above
+    ticket.
+
+  + Optimistic parse: Parsing is two phase, with the first phase assuming 
+    there will be no errors. This yields ~ 20% speed improvement in the 
+    case where the parse succeeds.
+    Also, internal error handling is now using tuples. This and other 
+    optimizations have yielded ~ 30% overall improvement. 
+
+  ! #error_tree and #cause removed from all of parslet. The 
+    Parslet::ParseFailed exception now contains a #cause field that can
+    be asked for an #ascii_tree as before. 
+    Cleaner internal error handling, not stateful in atoms anymore. Some 
+    parsers will see correct error reporting for the first time. (issue #65)
+
+  + Made it possible to pass a custom Parslet::Source implementor to #parse.
+    (see #63)
+    
+  + #parse has now a second argument that is an options hash. See 
+    Parslet::Atoms::Base#parse for documentation.
+
+  - VM engine on the way out. No benefit except for the intellectual
+    challenge.
+    
+= 1.3.0 / 5Mar2012
+
+  ! Parslet::Transform::Context is now much more well-behaved. It has
+    #respond_to? and #method_missing; it now looks like a plain old Ruby
+    object with instance variables and attribute readers.
+
+  - Grammar transforms turned out to be a dead end and have been removed. 
+
+  ! A few problems in error message generation have been fixed. This will
+  	improve diagnostics further.
+	
+  + A VM driven parser engine: Removes the limitation that parsing needs a 
+    lot of stack space, something dearly missing from Ruby 1.9.3 fibers.
+    This engine is experimental and might be removed in the future. 
+
+  ! Interaction with mathn fixed - Line number generation will terminate. 
+	
+  . Internal reorganisation, removing cruft and bit rot.
+    
+= 1.2.3 / 22Sep2011
+
+  + Transform#apply can now be called with a hash as second argument. This 
+    provides bindings and a way to inject context.
+
+  ! Fixes a bug thar modified parslet atoms in place, defeating oop chaining. 
+    (#50)
+    
+= 1.2.1 / 6Jun2011
+
+  ! FIX: Input at the end of a parse raises Parslet::UnconsumedInput. (see
+    issue 18)
+
+  ! FIX: Unicode parsing should now work as expected. (see issue 38)
+  
+  ! FIX: Slice#slice returned wrong bits at times (see issue 36).
+
+= 1.2.0 / 4Feb2011
+  
+  + Parslet::Parser is now also a grammar atom, it can be composed freely with
+    other atoms. (str('f') >> MiniLispParser.new >> str('b'))
+    
+  + No strings, only slices are returned as part of the parser result. 
+    Parslet::Slice is almost a string class, but one that remembers the 
+    source offset. This has also bought us a slight speedup.
+    
+  + require 'parslet/convenience' now brings #parse_with_debug to all parslets.
+    This is a consequence of the above change. 
+  
+  + Deprecates prsnt? and absnt? in favor of the more readable absent? and
+    prsnt?. Uses 3 bytes more RAM. The old variants will exist until we release
+    2.0. 
+  
+  INTERNALLY
+  
+  + Visitors now should have methods that all begin with 'visit_*'. #str 
+    becomes #visit_str.
+
+  + Parslet::Atoms::Entity now takes only a block argument instead of context
+    and block. 
+
+= 1.1.1 / 4Feb2011
+
+  ! FIX: Line counting was broken by performance optimisations. 
+  
+  + Squeezed out another few drops of performance. 
+
+= 1.1.0 / 2Feb2011
+  
+  + Uses return (fail/success), cached line counts, memoizing of parse results 
+    and other tricks internally for at least an order of magnitude increase 
+    in execution speed.
+    
+  + str('foo').maybe will now return an empty string again. Use .as(...) to 
+    name things and get back [] from #repeat and nil from #maybe.
+    
+  + If you require 'parslet/atoms/visitor', you'll get an accept method on
+    all known Parslet::Atoms.
+    
+  + If you require 'parslet/export', you can call #to_citrus and #to_treetop
+    to produce string versions of your grammar in those dialects.
+  
+  + Requiring 'parslet/convenience' will given you a parse_with_debug on 
+    your Parslet::Parser class. This prints some diagnostics on parse failure. 
+    (Thanks to Florian Hanke)
+        
+= 1.0.1 / 17Jan2011
+
+  A happy new year!
+  
+  ! FIX: Parslet::Transform was wrongly fixed earlier - it now wont mangle 
+    hashes anymore. (Blake Sweeney)
+    
+  + parslet/rig/rspec.rb contains useful rspec matchers. (R. Konstantin Haase)
+
+= 1.0.0 / 29Dez2010
+
+  - #each_match was removed. There was some duplication of code that even 
+    confused me - and we should not have 2 methods of achieving the same
+    goal. 
+    
+  + Full documentation. Fixed sdoc. 
+
+= 0.11.0 / 25Nov2010
+
+  ! Bugfixes to tree handling. Let's hope that was the last such significant
+    change to the core.
+
+= 0.10.1 / 22Nov2010
+
+  + Allow match['a-z'], shortcut for match('[a-z]')
+
+  ! Fixed output inconsistencies (behaviour in connection to 'maybe')
+
+= 0.10.0 / 22Nov2010
+
+  + Parslet::Transform now takes a block on initialisation, wherein you can
+    define all the rules directly.
+    
+  + Parslet::Transform now only passes a hash to the block during transform
+    when its arity is 1. Otherwise all hash contents as bound as local     
+    variables.
+    
+  + Both inline and other documentation have been improved. 
+  
+  + You can now use 'subtree(:x)' to bind any subtree to x during tree pattern
+    matching. 
+    
+  + Transform classes can now include rules into class definition. This makes
+    Parser and Transformer behave the same. 
+  
+= 0.9.0 / 28Oct2010
+  * More of everything: Examples, documentation, etc...
+
+  * Breaking change: Ruby's binary or ('|') is now used for alternatives, 
+    instead of the division sign ('/') - this reduces the amount of 
+    parenthesis needed for a grammar overall. 
+
+  * parslet.maybe now yields the result or nil in case of parse failure. This
+    is probably better than the array it did before; the jury is still out on
+    that. 
+    
+  * parslet.repeat(min, max) is now valid syntax
+
+= 0.1.0 / not released.
+
+  * Initial version. Classes for parsing, matching in the resulting trees
+    and transforming the trees into something more useful.  
+    
+  * Parses and outputs intermediary trees
+    
+  * Matching of single elements and sequences

+INTRODUCTION
+
+Parslet makes developing complex parsers easy. It does so by
+
+* providing the best error reporting possible
+* not generating reams of code for you to debug
+
+Parslet takes the long way around to make your job easier. It allows for
+incremental language construction. Often, you start out small, implementing
+the atoms of your language first; _parslet_ takes pride in making this
+possible.
+
+Eager to try this out? Please see the associated web site:
+http://kschiess.github.com/parslet
+
+SYNOPSIS
+
+  require 'parslet'
+  include Parslet
+
+  # parslet parses strings
+  str('foo').
+    parse('foo') # => "foo"@0
+
+  # it matches character sets
+  match['abc'].parse('a') # => "a"@0
+  match['abc'].parse('b') # => "b"@0
+  match['abc'].parse('c') # => "c"@0
+
+  # and it annotates its output
+  str('foo').as(:important_bit).
+    parse('foo') # => {:important_bit=>"foo"@0}
+
+  # you can construct parsers with just a few lines
+  quote = str('"')
+  simple_string = quote >> (quote.absent? >> any).repeat >> quote
+
+  simple_string.
+    parse('"Simple Simple Simple"') # => "\"Simple Simple Simple\""@0
+
+  # or by making a fuss about it 
+  class Smalltalk < Parslet::Parser
+    root :smalltalk
+
+    rule(:smalltalk) { statements }
+    rule(:statements) { 
+      # insert smalltalk parser here (outside of the scope of this readme)
+    }
+  end
+
+  # and then
+  Smalltalk.new.parse('smalltalk')
+
+FEATURES
+
+  * Tools for every part of the parser chain
+  * Transformers generate Abstract Syntax Trees
+  * Accelerators transform parsers, making them quite a bit faster
+  * Pluggable error reporters
+  * Graphviz export for your parser
+  * Rspec testing support rig
+  * Simply Ruby, composable and hackable
+
+COMPATIBILITY
+
+This library is intended to work with Ruby variants >= 1.9. I've tested it on 
+MRI 1.9, rbx-head, jruby. Please report as a bug if you encounter issues.
+
+STATUS 
+
+Production worthy.

+# The first stage is traditionally intermingled with the second stage; output

+# Transforms an expression tree into something else. The transformation
+# performs a depth-first, post-order traversal of the expression tree. During
+# that traversal, each time a rule matches a node, the node is replaced by the
+# result of the block associated to the rule. Otherwise the node is accepted
+# as is into the result tree.
+#
+# This is almost what you would generally do with a tree visitor, except that
+# you can match several levels of the tree at once. 
+#
+# As a consequence of this, the resulting tree will contain pieces of the
+# original tree and new pieces. Most likely, you will want to transform the
+# original tree wholly, so this isn't a problem.
+#
+# You will not be able to create a loop, given that each node will be replaced
+# only once and then left alone. This means that the results of a replacement
+# will not be acted upon. 
+#
+# Example: 
+#
+#   class Example < Parslet::Transform
+#     rule(:string => simple(:x)) {  # (1)
+#       StringLiteral.new(x)
+#     }
+#   end
+#
+# A tree transform (Parslet::Transform) is defined by a set of rules. Each
+# rule can be defined by calling #rule with the pattern as argument. The block
+# given will be called every time the rule matches somewhere in the tree given
+# to #apply. It is passed a Hash containing all the variable bindings of this
+# pattern match. 
+#   
+# In the above example, (1) illustrates a simple matching rule. 
+#
+# Let's say you want to parse matching parentheses and distill a maximum nest
+# depth. You would probably write a parser like the one in example/parens.rb;
+# here's the relevant part: 
+#
+#   rule(:balanced) {
+#     str('(').as(:l) >> balanced.maybe.as(:m) >> str(')').as(:r)
+#   }
+#
+# If you now apply this to a string like '(())', you get a intermediate parse
+# tree that looks like this: 
+#
+#   {
+#     l: '(', 
+#     m: {
+#       l: '(', 
+#       m: nil, 
+#       r: ')' 
+#     }, 
+#     r: ')' 
+#   }
+#
+# This parse tree is good for debugging, but what we would really like to have
+# is just the nesting depth. This transformation rule will produce that: 
+#
+#   rule(:l => '(', :m => simple(:x), :r => ')') { 
+#     # innermost :m will contain nil
+#     x.nil? ? 1 : x+1
+#   }
+#
+# = Usage patterns
+#
+# There are four ways of using this class. The first one is very much
+# recommended, followed by the second one for generality. The other ones are
+# omitted here. 
+#
+# Recommended usage is as follows: 
+#
+#   class MyTransformator < Parslet::Transform
+#     rule(...) { ... }
+#     rule(...) { ... }
+#     # ...
+#   end
+#   MyTransformator.new.apply(tree)
+#
+# Alternatively, you can use the Transform class as follows: 
+#
+#   transform = Parslet::Transform.new do
+#     rule(...) { ... }
+#   end
+#   transform.apply(tree)
+#
+# = Execution context
+#
+# The execution context of action blocks differs depending on the arity of 
+# said blocks. This can be confusing. It is however somewhat intentional. You 
+# should not create fat Transform descendants containing a lot of helper methods, 
+# instead keep your AST class construction in global scope or make it available
+# through a factory. The following piece of code illustrates usage of global
+# scope: 
+#
+#   transform = Parslet::Transform.new do
+#     rule(...) { AstNode.new(a_variable) }
+#     rule(...) { Ast.node(a_variable) } # modules are nice
+#   end
+#   transform.apply(tree)
+#
+# And here's how you would use a class builder (a factory):
+#
+#   transform = Parslet::Transform.new do
+#     rule(...) { builder.add_node(a_variable) }
+#     rule(...) { |d| d[:builder].add_node(d[:a_variable]) }
+#   end
+#   transform.apply(tree, :builder => Builder.new)
+#
+# As you can see, Transform allows you to inject local context for your rule
+# action blocks to use.

+# Parslet Accelerator
+
+## Synopsis
+
+Reading this all the way is worth it. But don't despair; if your attention span is short, read this and zap away! The TLDR: 
+
+Parslet is slow because of the way it is constructed internally. Optimisation helps, but makes your parser harder to read. Don't go there. Use parser accelerators instead - optimize parts of your parser without changing its definition. This is what it looks like: 
+
+    slow_parser = something >> slow_part >> other
+    
+    include Parslet::Accelerator
+    optimized_parser = apply(
+      rule( slow_part ) { faster_part })
+    
+    optimized_parser.parse('"Parsing is now fully optimized! (tm)"')    
+    
+Thus parslet allows you to write cristal clear parsers that are also as fast as you can make them. (But still slower than C!)
+
+## Introduction
+
+The goals of parslet are simple: make writing PEG parsers a predictable and straightforward endeavour. Some people have since claimed the word 'fun' for writing parsers, a connotation that we don't entirely oppose - otherwise why would we spend our time extending parslet?
+
+### Dark Clouds ahead
+
+Writing your first thousand line parser that works is easy – IF you use parslet. But very often, the resulting parser is rather slow - having execution times in the second range instead of the subsecond range. 
+
+You fire up your email client and drop us a mail to the mailing list, asking: "Why is parslet so slow?" You'll receive the following answers: 
+
+* Parslet is not a parser generator, but a parser engine based on Ruby. As such, it will be slower than parsers written in languages such as C. 
+* Parslet's internal structure is simple and clear. We've invested a lot of effort in making everything it does obvious and extendable. The downside of this somewhat OO-heavy approach is that we've got many objects juggling data and deep callstacks. Read: Bad use of caches and CPU time. 
+* Very few big languages have parsers written in high level languages such as Ruby. For good reasons. Depending on how serious you are about writing a new language (as opposed to fiddling around), you might want to _not start with parslet at all_.
+
+It's not like we haven't done anything to fix the above reasons; rather, we're doing everything we can, provided the main goal of *simplicity and understandability* is not in danger! If you look up what has been done over the years you will find a lot of small and large optimisations. But we have always refused to sacrifice simplicity of design to the god of optimisation, especially when it came to making a single parser faster. We want parslet to be fast in general, and frankly, your parser of language X is not our concern - only insofar as it uses parslet.
+
+But parslet needs to be useful for something. If not, what is the point? We would like to make parslet as useful as possible for smaller languages and for places where execution speed isn't your only concern. A lot of languages have rapidly evolving grammars and are developed by programmers that don't have the time for hand-writing parsers in C. 
+
+Still, what should you do once you've written your parser and speed becomes the issue? Until now, you had no real options short of rewriting the damn thing in C. That has changed: we've come up with Parslet Accelerator. The Accelerator will allow you to pattern match bits of your _parser_ and replace them with bits that do the same work, but faster. Really just hot spot optimisation, but without sacrificing readability of the original parser grammar.
+
+### An Example
+
+Let's consider the parser for quoted strings as an example, usually written to look something like this: 
+
+    quote = str('"')
+    quote >> (quote.absent? >> any).repeat >> quote
+    
+If we spell out the work parslet needs to do when matching a 1000 character string using this method, the performance problems will become obvious to you. Parslet will: 
+
+* Match a quote
+* In a loop: 
+  * Try to match a quote
+  * If that fails, continue, otherwise break from the loop
+  * Gobble up a single char
+* Match the final quote
+
+The inner loop will be executed a 1000 times; that's a 1000 times reading a char, checking to see if it's a quote, then reading it again, etc... As a programmer, this should disturb you deeply. And the fix, pseudo-code wise, should be obvious to you. Let's look at this revised flow: 
+
+* Match a quote
+* Gobble up as many chars as possible, until we hit a quote
+* Match the final quote
+
+Ok, we've sort of cheated there in the middle - we've transformed something into a single step that is really still a loop. But as a Ruby programmer, you will not see this as a loop, but rather as a call to a more efficient library like `StringScanner`, which underlies `Parslet::Source`.
+
+So we're pretty confident that this new parser will work faster; maybe fast even. Let's assume that we've got a `GobbleUp` atom that gobbles up chars until it hits a stop char. Our faster parser would have to look something like this: 
+
+    quote = str('"')
+    quote >> GobbleUp.new('"') >> quote
+    
+And all is fine, right? We don't think so. You've chosen to use parslet, so you don't want to end up sprinkling your grammar which is as much specification as it is implementation with things like `GobbleUp`. Wouldn't it be nice if you could keep the parser as it is, but somehow replace the pattern of `(quote.absent? >> any).repeat` with `GobbleUp.new('"')` before doing any work with your parser? Well, you can.
+
+    quote = str('"')
+    parser = quote >> (quote.absent? >> any).repeat >> quote
+    
+    A = Accelerator # for making what follows a bit shorter
+    optimized_parser = A.apply(parser, 
+      A.rule( (A.str(:x).absent? >> A.any).repeat ) { GobbleUp.new(x) })
+    
+    optimized_parser.parse('"Parsing is now fully optimized! (tm)"')
+    
+(If you're interested in a bit of history, the example that triggered the discussion around accelerators is preserved in [optimizer.rb](https://github.com/kschiess/parslet/blob/master/experiments/optimizer.rb). If you look past the hacks and the optimism, you'll recognize some of the things we talk about in this document.)
+
+### About this Document
+
+Now that the goal is defined, let us expose the details of the system proposed above. We'll start with explaining what these `Accelerator.rule` things are, how they match against your parser and how binding of variables work. (*Parslet Pattern Matching*) Then we'll explain what actions you can take once you've matched part of your parser. (*Binding and Actions*)
+
+## Parser Pattern Matching
+
+We'll demonstrate how pattern detection is constructed by showing what the smallest parts do first. Let's require needed libraries.
+
+    require 'parslet'
+    require 'parslet/accelerator'
+    
+    include Parslet
+    
+The whole optimizer code is inside the `Parslet::Accelerator` module. If you read that, read 'particle accelerator', not 'will make my code fast'. It is very possible to make things worse using `Parslet::Accelerator`. 
+    
+The simplest parser I can think of would be the one matching a simple string.
+
+    atom = str('foo')
+    expression = Accelerator.str(:x)
+    binding = Accelerator.match(atom, expression)
+
+    binding[:x].assert == 'foo'
+    
+Note that the above was somewhat verbose, with all these variables and all that. We'll write shorter examples from now on. 
+
+Another simple parser is the one that matches against variants of the `match(...)` atom. Multiple forms of this exist, so we'll go through all of them. First comes a simple character range match.
+
+    binding = Accelerator.match(
+      match['a-z'],
+      Accelerator.re(:x))
+      
+    binding[:x].assert == '[a-z]'
+
+Note how the internal regular expression value used for the match atom is really bound to :x – we'll keep this as a convention. This also means that some parslet internas are leaked through the Accelerator API here. We consider that a feature, since working with accelerators will bring you into close contact with the atoms internas.
+
+Also the Accelerator matcher for `Parslet.match` is called `Accelerator.re` - the reason for this should be obvious from what stands above. 
+
+Just to make this complete, a special case for the `match(...)` atom is the `any` atom. 
+
+    binding = Accelerator.match(any, Accelerator.any)
+    binding.assert != nil
+
+## Composite Parsers
+
+Let's start assembling these simple parsers into more complex patterns and match those. As our first pattern, we'll consider sequences.
+
+    binding = Accelerator.match(
+      str('a') >> str('b'), 
+      Accelerator.str(:x) >> Accelerator.str(:y))
+      
+    binding.values_at(:x, :y).assert == %w(a b)
+
+Also, alternatives should correctly bind. 
+
+    binding = Accelerator.match(
+      str('a') | str('b'), 
+      Accelerator.str(:x) | Accelerator.str(:y))
+
+    binding.values_at(:x, :y).assert == %w(a b)
+
+Note that this means that we bind to the whole alternative subtree, not either to the left or to the right. We're matching the parslet tree, so the meaning of the alternative is irrelevant. 
+
+Let's quickly skip through the list of other composite parsers here: First off is repetition. 
+
+    Accelerator.match(
+      str('a').repeat(1,2), 
+      A.str('a').repeat(1,2)).assert != nil
+
+And then there is positive and negative lookahead.
+
+    Accelerator.match(
+      str('a').present?, 
+      A.str('a').present?).assert != nil
+
+    Accelerator.match(
+      str('a').absent?, 
+      A.str('a').absent?).assert != nil
+      
+And named values.
+
+    Accelerator.match(
+      str('a').as(:a), 
+      A.str('a').as(:a)).assert != nil
+      
+Which we also want to be able to bind.
+
+    Accelerator.match(
+      str('a').as(:a), 
+      A.str('a').as(:b)).assert == {:b => :a}
+    
+## Binding to Values
+
+As a side note, our parser should also respect literal value matches in the pattern and only bind to subsequent locations when the values match up. 
+
+    binding = Accelerator.match(
+      str('a') >> str('b'), 
+      Accelerator.str(:x) >> Accelerator.str(:x))
+  
+    binding.assert == nil
+    
+Another property should be that literal strings passed to the pattern should be matched using ===. 
+
+    binding = Accelerator.match(
+      str('abc') >> str('bcd'), 
+      Accelerator.str(/b/) >> Accelerator.str('bcd'))
+  
+    binding.assert == {}
+
+The binding is empty here, since no variables were given. But lets also implement constrained variable bindings, that seems useful. The way this works is that you specify a variable you want to bind to first, and then a list of constraints that are matched by `#===`.
+
+    A.match(str('abc'), A.str(:x, /c/))[:x].assert == 'abc'
+    A.match(str('abc'), A.str(:x, /d/)).assert == nil
+   
+    A.match(str('abc'), A.str(:x, /a/, /c/))[:x].assert == 'abc'
+    A.match(str('abc'), A.str(:x, /a/, /d/)).assert == nil
+    
+Here's a quick demonstration that demonstrates that this feature equally applies to both `Accelerator.re` and `Parslet.match`. 
+
+    A.match(match['abc'], A.re(:x, /d/)).assert == nil
+    A.match(match['abc'], A.re(:x, /c/))[:x].assert == '[abc]'
+

+      <div class="content">
+        <h1>Get Started</h1><p>Let’s develop a small language that allows for simple computation together. 
+Here’s a valid input file for that language:</p>
+<pre class="sh_ruby"><code> 
+  puts(1 + 2)
+  puts(4 + 2)
+</code></pre>
+<p>To install the parslet library, please do a</p>
+<pre><code> 
+  gem install parslet
+</code></pre>
+<p>Now let’s write the first part of our parser. For now, we’ll just recognize
+simple numbers like ‘1’ or ‘42’.</p>
+<pre class="sh_ruby"><code title="mini_parser"> 
+  require 'parslet' 
+
+  class Mini < Parslet::Parser
+    rule(:integer) { match('[0-9]').repeat(1) }
+    root(:integer)
+  end
+
+  Mini.new.parse("132432")  # => "132432"@0
+</code></pre>
+<p>Running this example will print “132432 at 0”. Congratulations! You just have
+written your first parser. Running it on the input ‘<code>puts(1)</code>’ will
+not work yet. Let’s see what happens in case of a failure:</p>
+<pre class="sh_ruby"><code> 
+  Mini.new.parse("puts(1)") # raises Parslet::ParseFailed
+</code></pre>
+<p>Here’s the error message provided by that exception: “Expected at least 1 of
+[0-9] at line 1 char 1.” parslet tries to find a number there, but can’t find
+one.</p>
+<p>There are just two lines to the definition of this parser, let’s go through
+them:</p>
+<pre class="sh_ruby"><code> 
+  rule(:integer) { match('[0-9]').repeat(1) }
+</code></pre>
+<p><code>rule</code> lets you create a new parser rule. Inside the block of that
+<code>:integer</code> rule, you find <code>match('[0-9]').repeat(1)</code>.
+This says: “match a character that is in the range <code>0-9</code>, then
+match any number of those, but at least match one.”</p>
+<pre class="sh_ruby"><code> 
+  root(:integer)
+</code></pre>
+<p>That second line just says: Start parsing at the rule called
+<code>:integer</code>.</p>
+<h2>Addition</h2>
+<p>Let’s go for simple addition. We’ll have to allow for spaces in our input,
+since those help make code readable.</p>
+<pre class="sh_ruby"><code> 
+  rule(:space)  { match('\s').repeat(1) }
+  rule(:space?) { space.maybe }
+</code></pre>
+<p>Two things are new here: (and both in the second line)</p>
+<ul>
+	<li>you can use (‘call’) other rules in your rules</li>
+	<li><code>.maybe</code>, the same as <code>.repeat(0,1)</code><sup class="footnote" id="fnr1"><a href="#fn1">1</a></sup>, indicating 
+  that the thing before it is maybe present once in the input.</li>
+</ul>
+<p>Essentially, you can think about parslet rules as instructing Ruby to “parse
+this” and “parse that”. Calling other rules can be looked at in the same way;
+you tell Ruby to go off, parse that subrule and then come back with the
+results. This helps when thinking about rule recursion. For example, a
+self-recursive rule like this one will of course create an endless loop:</p>
+<pre class="sh_ruby"><code> 
+  rule(:infinity) {
+    infinity >> str(';')
+  }
+</code></pre>
+<p>Even though infinity seems to be delimited by ‘;’, in reality, infinity is
+very long, especially towards the end. There is no way of knowing for the
+parser when to stop processing <code>infinity</code> and start reading
+semicolons. Ergo, we need to make sure we talk about concrete items that
+consume input first, and then do recursion. This way we ensure that our
+grammar terminates, since in a way, it is like a normal program.</p>
+<p>Here’s the full parser:</p>
+<pre class="sh_ruby"><code title="full_parser">  
+  class Mini < Parslet::Parser
+    rule(:integer)    { match('[0-9]').repeat(1) >> space? }
+  
+    rule(:space)      { match('\s').repeat(1) }
+    rule(:space?)     { space.maybe }
+  
+    rule(:operator)   { match('[+]') >> space? }
+  
+    rule(:sum)        { integer >> operator >> expression }
+    rule(:expression) { sum | integer }
+
+    root :expression
+  end
+
+  def parse(str)
+    mini = Mini.new
+  
+    mini.parse(str)
+  rescue Parslet::ParseFailed => failure
+    puts failure.cause.ascii_tree
+  end
+
+  parse "1 + 2 + 3"  # => "1 + 2 + 3"@0
+  parse "a + 2"      # fails, see below
+</code></pre>
+<p>As you can see, the parser got decorated with the <code>space?</code> idiom.
+Every atom of our language consumes the space right after it. This is a useful
+convention that makes top level rules (the important ones) look cleaner.</p>
+<p>Note also the addition of <code>:operator</code>, <code>:sum</code> and
+<code>:expression</code>. The runner code has been extended a bit, so as to
+throw nice explanations of what went wrong when a parse failure is
+encountered. Running the code on ‘<code>a + 2</code>’ for example outputs:</p>
+<pre class="output">  
+Expected one of [SUM, INTEGER] at line 1 char 1.
+|- Failed to match sequence (INTEGER OPERATOR EXPRESSION) at line 1 char 1.
+|  `- Failed to match sequence ([0-9]{1, } SPACE?) at line 1 char 1.
+|     `- Expected at least 1 of [0-9] at line 1 char 1.
+|        `- Failed to match [0-9] at line 1 char 1.
+`- Failed to match sequence ([0-9]{1, } SPACE?) at line 1 char 1.
+   `- Expected at least 1 of [0-9] at line 1 char 1.
+      `- Failed to match [0-9] at line 1 char 1.
+</pre>
+<p>This is what parslet calls an <code>#error_tree</code>. Not only the output of
+your parser, but also its grammar is constructed like a tree. When things go
+wrong, every branch of the tree has its own reasons for not accepting a given
+input. The <code>#cause</code> method returns those reasons.</p>
+<p>Our grammar has essentially two branches, <code>SUM</code> and
+<code>INTEGER</code>. Can you see why all rules expect a number as the first
+character?</p>
+<h2>Tree output (and what to do about it)</h2>
+<p>But if we leave the negative examples for a second; what happens if the parse
+succeeds? It turns out, not much:</p>
+<pre class="sh_ruby"><code>
+  parse "1 + 2 + 3"  # => "1 + 2 + 3"@0
+</code></pre>
+<p>The only notable difference between input and output is that the output has an
+extra ‘@0’ appended to it. This is related to line number tracking and will be
+explained later on (or you can skip ahead and look up
+<code>Parslet::Slice</code>).</p>
+<p>The code we now have parses the input successfully, but doesn’t do much else. 
+Parslet hasn’t got its own opinion on what to do with your input. By default, 
+it will just play it back to you. But parslet provides also a method of 
+structuring its output:</p>
+<pre class="sh_ruby"><code title="output_samples"> 
+  # Without structure: just strings.

+<p>You get to name things the way you want! This is also free. Seriously: parslet
+requires you to add all the structure to its output. Annotate important parts
+of your grammar with <code>.as(:symbol)</code> and get back a tree-like
+structure composed of hashes (sequence), arrays (repetition) and strings (like
+we had initially).</p>
+<p>Once you start naming things, you’ll notice that what you don’t name,
+disappears. Parslet assumes that <em>what you don’t name is unimportant</em>.</p>
+<pre class="sh_ruby"><code title="inline_parser"> 
+parser =  str('a').as(:a) >> str(' ').maybe >> 
+          str('+').as(:o) >> str(' ').maybe >> 
+          str('b').as(:b)
+parser.parse('a + b') # => {:a=>"a"@0, :o=>"+"@2, :b=>"b"@4}
+</code></pre>
+<p>Think of this like using a highlighter on your input: What is there not to
+like about neon yellow?</p>
+<h2>Making the parser complete</h2>
+<p>Let’s look at the complete parser definition that also allows for function
+calls:</p>
+<pre class="sh_ruby"><code title="full_parser"> 
+class MiniP < Parslet::Parser
+  # Single character rules
+  rule(:lparen)     { str('(') >> space? }
+  rule(:rparen)     { str(')') >> space? }
+  rule(:comma)      { str(',') >> space? }
+
+  rule(:space)      { match('\s').repeat(1) }
+  rule(:space?)     { space.maybe }
+
+  # Things
+  rule(:integer)    { match('[0-9]').repeat(1).as(:int) >> space? }
+  rule(:identifier) { match['a-z'].repeat(1) }
+  rule(:operator)   { match('[+]') >> space? }
+  
+  # Grammar parts
+  rule(:sum)        { integer.as(:left) >> operator.as(:op) >> expression.as(:right) }
+  rule(:arglist)    { expression >> (comma >> expression).repeat }
+  rule(:funcall)    { identifier.as(:funcall) >> lparen >> arglist.as(:arglist) >> rparen }
+  
+  rule(:expression) { funcall | sum | integer }
+  root :expression
+end
+
+require 'pp'
+pp MiniP.new.parse("puts(1 + 2 + 3, 45)")
+</code></pre>
+<p>That’s really all there is to it — our language is a really simple language. 
+When fed with a string like ’<code>puts(1 + 2 + 3, 45)</code>, our parser outputs
+the following:</p>
+<pre class="output"> 
+{:funcall=>"puts"@0,
+ :arglist=>
+  [{:left=>{:int=>"1"@5},
+    :op=>"+ "@7,
+    :right=>{:left=>{:int=>"2"@9}, :op=>"+ "@11, :right=>{:int=>"3"@13}}},
+   {:int=>"45"@16}]}
+</code></pre>
+<p>Parslet calls this the <em>intermediary tree</em>. There are three types of nodes in
+this tree:</p>
+<ul>
+	<li><strong>Hashes</strong>: a node that has named subtrees</li>
+	<li><strong>Arrays</strong>: a node storing a collection of sub-nodes</li>
+	<li><strong>Strings</strong> are the leaves, containing the <em>accepted source</em></li>
+</ul>
+<p>The format of this tree is easy to work with and to read. Here’s what the
+above tree would look like as a graphic:</p>
+<p><img src="images/ast.png" alt="" /></p>
+<h2>Where to go from here: An Interpreter</h2>
+<p>As nice as the format above is for printing and looking at – it may be
+difficult at times to get the information out of it again. Let’s look at how
+to transform the tree:</p>
+<pre class="sh_ruby"><code> 
+class SimpleTransform < Parslet::Transform
+  rule(funcall: 'puts', arglist: sequence(:args)) {
+    "puts(#{args.inspect})"
+  }
+  # ... other rules
+end
+
+tree = {funcall: 'puts', arglist: [1,2,3]}
+SimpleTransform.new.apply(tree) # => "puts([1, 2, 3])"
+</code></pre>
+<p>Transformation is an entire topic by itself; this will be covered in detail
+<a href="transform.html">later on</a>. To whet your appetite, let me just give you a few
+teasers:</p>
+<ul>
+	<li>Transformations match portions of your tree at any depth, replacing them
+  with whatever you decide.</li>
+	<li>In addition to <code>sequence(sym)</code>, there is also
+  <code>simple(sym)</code> and <code>subtree(sym)</code>. Those match simple
+  strings and entire subtrees respectively. Caution with the latter.</li>
+</ul>
+<p>Here’s how you would write a somewhat classical interpreter for our little 
+language by using a transformation. Note that from this point on, there is
+not one way to go about this, but thousands; you are really free (and on
+your own):</p>
+<pre class="sh_ruby"><code title="putting it all together">

+<p>That’s a bunch of code for printing <code>[1, 2, 3, 9]</code>. Welcome to the
+fantastic world of compiler and interpreter writing!</p>
+<p><sup class="footnote" id="fnr1"><a href="#fn1">1</a></sup> As far as parsing goes. There is a subtle difference between

+<p>A small Ruby library for constructing parsers in the
+<a href="http://en.wikipedia.org/wiki/Parsing_expression_grammar"><span class="caps">PEG</span></a> (Parsing
+Expression Grammar) fashion.</p>
+<p>Parslet makes developing complex parsers easy. It does so by</p>
+<ul>
+	<li>providing the best <strong>error reporting</strong> possible</li>
+	<li><strong>not generating</strong> reams of code for you to debug</li>
+</ul>
+<p>Parslet takes the long way around to make <strong>your job</strong> easier. It allows for
+incremental language construction. Often, you start out small, implementing
+the atoms of your language first; <em>parslet</em> takes pride in making this
+possible.</p>

+        <h1>Overview</h1><p>Parslet is a library with a clear philosophy: It makes parser writing easy and
+        testable. On top of that, it provides understandable error messages (“General
+        Protection Fault”) to you, the language writer. In extension, you will
+        hopefully manage to provide good error messages to your users. Together, we 
+        can create a better world!</p>
+        <p>Traditional texts on the subject will have you write a compiler or interpreter
+        for a language in several stages:</p>
+        <ul>
+        	<li>Parsing or Lexing/Parsing</li>
+        	<li>Abstract Syntax Tree construction</li>
+        	<li>Optimization and checking of the tree</li>
+        	<li>Generation of code / Execution</li>
+        </ul>
+        <p>This library will be good for the first two stages only. After that, you’ll
+        be on your own.</p>
+        <p>The parsing step has literally been implemented by hundreds (thousands) of
+        clever people; No lack of alternatives. Even in Ruby, you’ll have the choice 
+        among a handful of libraries. There’s a distinction to make on this level as
+        well:</p>
+        <p><strong>LRk parsers and related fields</strong> Parsers in this class use a lexical analyzer
+        (a <em>lexer</em> ) to transform the input text into tokens (<em>tokenizing</em> ). They
+        then check if your stream of tokens has a corresponding tree that conforms to
+        the grammar. Most of these parsers allow grammars that are ambiguous and will
+        provide a mechanism for resolving the arising ambiguities. These are the
+        earliest parser generators and the most widely used (<em>yacc</em>, <em>bison</em>, …) —
+        chances are, you’ll have more than one of these libraries installed on your
+        system.</p>
+        <p><strong><span class="caps">PEG</span> or packrat parsers</strong> Parsers in this class are based on a slightly more
+        modern algorithm, which translates what one does when writing a parser by hand
+        in top-down fashion. This is what we programmers do all over, methods calling
+        methods – and its also (grossly) what these parsers do to recognize input.
+        Left recursion is impossible to express in these grammars. No lexers are
+        required – lexical tokenizing and parsing are one single step. Ruby has
+        several implementations of this algorithm in library form:
+        <a href="http://github.com/nathansobo/treetop">Treetop</a>,
+        <a href="http://github.com/mjijackson/citrus">Citrus</a>,
+        <a href="http://wiki.github.com/luikore/rsec/">rsec</a> and of course
+        <a href="http://kschiess.github.com/parslet">Parslet</a>.</p>
+        <p>All of these generators are different in small ways; yet most implement common
+        patterns and provide almost identical APIs. We believe this is an error:
+        choice is good, but there should be visible attributes distinguishing the
+        choices.</p>
+        <p>Parslet is not like the others, in fact it is radically different on some
+        key elements.</p>
+        <h2>Writing a language</h2>
+        <p>Whether you write a language for a configuration file or a new computer
+        language (the holy grail), the steps are always the same:</p>
+        <ol>
+        	<li>Create a grammar: <em>What should be legal syntax?</em></li>
+        	<li>Annotate the grammar: <em>What is important data?</em></li>
+        	<li>Create a transformation: <em>How do I want to work with that data?</em></li>
+        </ol>
+        <p>The creation of grammars and the various concepts that are associated are treated
+        in <a href="parser.html">Parslet::Parser</a>.</p>
+        <p>Transformation of the resulting intermediary tree is treated in
+        <a href="transform.html">Parslet::Transform</a></p></div>

+        <h1>Parser construction</h1><p>A parser is nothing more than a class that derives from
+<code>Parslet::Parser</code>. The simplest parser that one could write would
+look like this:</p>
+<pre class="sh_ruby"><code>
+  class SimpleParser < Parslet::Parser
+    rule(:a_rule) { str('simple_parser') }
+    root(:a_rule)
+  end
+</code></pre>
+<p>The language recognized by this parser is simply the string “simple_parser”. 
+Parser rules do look a lot like methods and are defined by</p>
+<pre class="sh_ruby"><code>
+  rule(name) { definition_block }
+</code></pre>
+<p>Behind the scenes, this really defines a method that returns whatever you 
+return from it.</p>
+<p>Every parser has a root. This designates where parsing should start. It is like
+an entry point to your parser. With a root defined like this:</p>
+<pre class="sh_ruby"><code>
+  root(:my_root)
+</code></pre>
+<p>you create a <code>#parse</code> method in your parser that will start parsing
+by calling the <code>#my_root</code> method. You’ll also have a <code>#root</code>
+(instance) method that is an alias of the root method. The following things are
+really one and the same:</p>
+<pre class="sh_ruby"><code>
+  SimpleParser.new.parse(string)
+  SimpleParser.new.root.parse(string)
+  SimpleParser.new.a_rule.parse(string)
+</code></pre>
+<p>Knowing these things gives you a lot of flexibility; I’ll explain why at the
+end of the chapter. For now, just let me point out that because all of this is
+Ruby, your favorite editor will syntax highlight parser code just fine.</p>
+<h2>Atoms: The inside of a parser</h2>
+<h3>Matching strings of characters</h3>
+<p>A parser is constructed from parser atoms (or parslets, hence the name). The
+atoms are what appear inside your rules (and maybe elsewhere). We’ve already
+encountered an atom, the string atom:</p>
+<pre class="sh_ruby"><code>
+  str('simple_parser')
+</code></pre>
+<p>This returns a <code>Parslet::Atoms::Str</code> instance. These parser atoms
+all derive from <code>Parslet::Atoms::Base</code> and have essentially just
+one method you can call: <code>#parse</code>. So this works:</p>
+<pre class="sh_ruby"><code title="parser atoms">
+  str('foobar').parse('foobar') # => "foobar"@0
+</code></pre>
+<p>The atoms are small parsers that can recognize languages and throw errors, just
+like real <code>Parslet::Parser</code> subclasses.</p>
+<h3>Matching character ranges</h3>
+<p>The second parser atom you will have to know about allows you to match
+character ranges:</p>
+<pre class="sh_ruby"><code>
+  match('[0-9a-f]')
+</code></pre>
+<p>The above atom would match the numbers zero through nine and the letters ‘a’ 
+to ‘f’ – yeah, you guessed right – hexadecimal numbers for example. The inside
+of such a match parslet is essentially a regular expression that matches 
+a single character of input. Because we’ll be using ranges so much with 
+<code>#match</code> and because typing (‘[]’) is tiresome, here’s another way
+to write the above <code>#match</code> atom:</p>
+<pre class="sh_ruby"><code>
+  match['0-9a-f']
+</code></pre>
+<p>Character matches are instances of <code>Parslet::Atoms::Re</code>. Here are 
+some more examples of character ranges:</p>
+<pre class="sh_ruby"><code>
+  match['[:alnum:]']      # letters and numbers
+  match['\\n']            # newlines
+  match('\\w')            # word characters
+  match('.')              # any character
+</code></pre>
+<h3>The wild wild <code>#any</code></h3>
+<p>The last example above corresponds to the regular expression <code>/./</code> that matches
+any one character. There is a special atom for that:</p>
+<pre class="sh_ruby"><code>
+  any 
+</code></pre>
+<h2>Composition of Atoms</h2>
+<p>These basic atoms can be composed to form complex grammars. The following
+few sections will tell you about the various ways atoms can be composed.</p>
+<h3>Simple Sequences</h3>
+<p>Match ‘foo’ and then ‘bar’:</p>
+<pre class="sh_ruby"><code>
+  str('foo') >> str('bar')    # same as str('foobar')
+</code></pre>
+<p>Sequences correspond to instances of the class
+<code>Parslet::Atoms::Sequence</code>.</p>
+<h3>Repetition and its Special Cases</h3>
+<p>To model atoms that can be repeated, you should use <code>#repeat</code>:</p>
+<pre class="sh_ruby"><code>
+  str('foo').repeat
+</code></pre>
+<p>This will allow foo to repeat any number of times, including zero. If you
+look at the signature for <code>#repeat</code> in <code>Parslet::Atoms::Base</code>, 
+you’ll see that it has really two arguments: <em>min</em> and <em>max</em>. So the following
+code all makes sense:</p>
+<pre class="sh_ruby"><code>
+  str('foo').repeat(1)      # match 'foo' at least once
+  str('foo').repeat(1,3)    # at least once and at most 3 times
+  str('foo').repeat(0, nil) # the default: same as str('foo').repeat
+</code></pre>
+<p>Repetition has a special case that is used frequently: Matching something
+once or not at all can be achieved by <code>repeat(0,1)</code>, but also 
+through the prettier:</p>
+<pre class="sh_ruby"><code>
+  str('foo').maybe          # same as str('foo').repeat(0,1)
+</code></pre>
+<p>These all map to <code>Parslet::Atoms::Repetition</code>. Please note this
+little twist to <code>#maybe</code>:</p>
+<pre class="sh_ruby"><code title="maybes twist">
+  str('foo').maybe.as(:f).parse('')         # => {:f=>nil}
+  str('foo').repeat(0,1).as(:f).parse('')   # => {:f=>[]}
+</code></pre>
+<p>The ‘nil’-value of <code>#maybe</code> is nil. This is catering to the
+intuition that <code>foo.maybe</code> either gives me <code>foo</code> or
+nothing at all, not an empty array. But have it your way!</p>
+<h3>Alternation</h3>
+<p>The most important composition method for grammars is alternation. Without
+it, your grammars would only vary in the amount of things matched, but not
+in content. Here’s how this looks:</p>
+<pre class="sh_ruby"><code>
+  str('foo') | str('bar')   # matches 'foo' OR 'bar'
+</code></pre>
+<p>This reads naturally as “‘foo’ or ‘bar’”.</p>
+<h3>Operator precedence</h3>
+<p>The operators we have chosen for parslet atom combination have the operator
+precedence that you would expect. No parenthesis are needed to express
+alternation of sequences:</p>
+<pre class="sh_ruby"><code>
+  str('s') >> str('equence') | 
+    str('se') >> str('quence')
+</code></pre>
+<h3>And more</h3>
+<p>Parslet atoms are not as pretty as Treetop atoms. There you go, we said it. 
+However, there seems to be a different kind of aesthetic about them; they 
+are pure Ruby and integrate well with the rest of your environment. Have a 
+look at this:</p>
+<pre class="sh_ruby"><code>
+  # Also consumes the space after important things like ';' or ':'. Call this
+  # giving the character you want to match as argument: 
+  #
+  #   arg >> (spaced(',') >> arg).repeat
+  #
+  def spaced(character)
+    str(character) >> match["\s"]
+  end
+</code></pre>
+<p>or even this:</p>
+<pre class="sh_ruby"><code>
+  # Turns any atom into an expression that matches a left parenthesis, the 
+  # atom and then a right parenthesis.
+  #
+  #   bracketed(sum)
+  #
+  def bracketed(atom)
+    spaced('(') >> atom >> spaced(')')
+  end
+</code></pre>
+<p>You might say that because parslet is just plain old Ruby objects itself (<span class="caps">PORO</span>
+™), it allows for very tight code. Module inclusion, class inheritance, …
+all your tools should work well with parslet.</p>
+<h2>Tree construction</h2>
+<p>By default, parslet will just echo back to you the strings you feed into it. 
+Parslet will not generate a parser for you and neither will it generate your
+abstract syntax tree for you. The method <code>#as(name)</code> allows you
+to specify exactly how you want your tree to look like:</p>
+<pre class="sh_ruby"><code title="using as">
+  str('foo').parse('foo')             # => "foo"@0
+  str('foo').as(:bar).parse('foo')    # => {:bar=>"foo"@0}
+</code></pre>
+<p>So you think: <code>#as(name)</code> allows me to create a hash, big deal.
+That’s not all. You’ll notice that annotating everything that you want to keep
+in your grammar with <code>#as(name)</code> autocreates a sensible tree
+composed of hashes and arrays and strings. It’s really somewhat magic: Parslet
+has a set of clever rules that merge the annotated output from your atoms into
+a tree. Here are some more examples, with the atom on the left and the resulting
+tree (assuming a successful parse) on the right:</p>
+<pre class="sh_ruby"><code>
+  # Normal strings just map to strings
+  str('a').repeat                         "aaa"@0                                 
+
+  # Arrays capture repetition of non-strings
+  str('a').repeat.as(:b)                  {:b=>"aaa"@0}                           
+  str('a').as(:b).repeat                  [{:b=>"a"@0}, {:b=>"a"@1}, {:b=>"a"@2}] 
+
+  # Subtrees get merged - unlabeled strings discarded
+  str('a').as(:a) >> str('b').as(:b)      {:a=>"a"@0, :b=>"b"@1}                  
+  str('a') >> str('b').as(:b) >> str('c') {:b=>"b"@1}                             
+
+  # #maybe will return nil, not the empty array
+  str('a').maybe.as(:a)                   {:a=>"a"@0}                             
+  str('a').maybe.as(:a)                   {:a=>nil}
+</code></pre>
+<h2>Capturing input</h2>
+<p><em>Advanced reading material – feel free to skip this.</em></p>
+<p>Sometimes a parser needs to match against something that was already matched
+against. Think about Ruby heredocs for example:</p>
+<pre class="sh_ruby"><code>
+  str = <-HERE
+    This is part of the heredoc.
+  HERE
+</code></pre>
+<p>The key to matching this kind of document is to capture part of the input
+first and then construct the rest of the parser based on the captured part.
+This is what it looks like in its simplest form:</p>
+<pre class="sh_ruby"><code>
+  match['ab'].capture(:capt) >>               # create the capture
+    dynamic { |s,c| str(c.captures[:capt]) }  # and match using the capture
+</code></pre>
+<p>This parser matches either ‘aa’ or ‘bb’, but not mixed forms ‘ab’ or ‘ba’. The
+last sample introduced two new concepts for this kind of complex parser: the 
+<code>#capture(name)</code> method and the <code>dynamic { ... }</code> code
+block.</p>
+<p>Appending <code>#capture(name)</code> to any parser will capture that parsers
+result in the captures hash in the parse context. If and only if the parser
+<code>match['ab']</code> succeeds, it stores either ‘a’ or ‘b’ in 
+<code>context.captures[:capt]</code>.</p>
+<p>The only way to get at that hash during the parse process is in a
+<code>dynamic { ... }</code> code block. (for reasons that are out of the
+scope of this document) In such a block, you can:</p>
+<pre class="sh_ruby"><code>
+  dynamic { |source, context|
+    # construct parsers by using randomness
+    rand < 0.5 ? str('a') : str('b')
+    
+    # Or by using context information 
+    str( context.captures[:capt] )
+    
+    # Or by .. doing other kind of work (consumes 100 chars and then 'a')
+    source.consume(100)
+    return str('a')
+  }
+</code></pre>
+<h3>Scopes</h3>
+<p>What if you want to parse heredocs contained within heredocs? It’s turtles all
+the way down, after all. To be able to remember what string was used to
+construct the outer heredoc, you would use the <code>#scope { ... }</code>
+block that was introduced in parslet 1.5. Like opening a Ruby block, it allows
+you to capture results (assign values to variables) to the same names you’ve 
+already used in outer scope – <em>without destroying the outer scopes values for 
+these captures!</em>.</p>
+<p>Here’s an example for this: 
+<pre class="sh_ruby"><code>
+  str('a').capture(:a) >> scope { str('b').capture(:a) } >> 
+    dynamic { |s,c| str(c.captures[:a]) }
+</code></pre></p>
+<p>This parses ‘aba’ – if you understand that, you understand scopes and
+captures. Congrats.</p>
+<h2>And more</h2>
+<p>Now you know exactly how to create parsers using Parslet. Your parsers
+will output intricate structures made of endless arrays, complex hashes and 
+a few string leftovers. But your programming skills fail you when you try
+to put all this data to use. Selecting keys upon keys in hash after hash, you
+feel like a cockroach that has just read Kafka’s works. This is no fun. This 
+is not what you signed up for.</p>
+<p>Time to introduce you to <a href="transform.html">Parslet::Transform</a> and its workings.</p></div>

+        <h1>Transformation</h1><p>Parslet parsers output deep nested hashes. Those are nice for printing, but 
+hard to work with. The structure of the nested hashes is determined by the
+grammar and can thus vary largely. Testing for the presence of individual 
+keys would produce code that is hard to read and maintain.</p>
+<p>This is why parslet also comes with a hash transformation engine. To construct
+such a transform, you have to derive from <code>Parslet::Transform</code>:</p>
+<pre class="sh_ruby"><code title="simple transform">
+  class MyTransform < Parslet::Transform
+    rule('a') { 'b' }
+  end
+  MyTransform.new.apply('a') # => "b"
+</code></pre>
+<p>This is a transformation that replaces all ’a’s with ’b’s. A transformation
+rule has two parts: A <strong>pattern</strong> (here: <code>'a'</code>) and an <strong>action block</strong>
+(<code>{ 'b' }</code>).</p>
+<p>The engine will go through the input and traverse the tree in depth-first
+post-order fashion. This means that for a given tree node, it will first visit
+the children and only then look at the node itself. While traversing, all
+rules are tested in the order in which they are defined. If a rule matches, the
+corresponding tree is <em>replaced</em> by whatever the action block returns.</p>
+<p>Here’s another way of saying the same thing, perhaps more in line with what
+you need as a user of Parslet: <code>Parslet::Transform</code> is what allows
+you to transform the <span class="caps">PORO</span>-trees magically into a real abstract syntax tree.
+The rule definitions are the futuristic nano-machines that act on tree leaves
+first, eating them away and replacing them with contraptions of your own
+design. Here’s how that might look like in Ruby:</p>
+<pre class="sh_ruby"><code title="poro magic">
+  tree = {:left => {:int => '1'}, 
+          :op   => '+', 
+          :right => {:int => '2'}}
+        
+  class Trans < Parslet::Transform
+    rule(:int => simple(:x)) { Integer(x) }
+  end
+  Trans.new.apply(tree)     # => {:left=>1, :op=>"+", :right=>2}
+</code></pre>
+<p>You can start thinking about the leaves first, transforming those <code>:int
+=> '1'</code> into real Ruby integers. This incremental (test driven!)
+approach will prevent your intermediary tree from turning into grey goo
+from too many nano-machines. Rules should in general be simple and transform
+a small part of the tree into a more useful variant. Turns out that if we were
+looking for an interpreter, one more rule will give us evaluation:</p>
+<pre class="sh_ruby"><code title="building up">
+  tree = {:left => {:int => '1'}, 
+          :op   => '+', 
+          :right => {:int => '2'}}
+
+  class Trans < Parslet::Transform
+    rule(:int => simple(:x)) { Integer(x) }
+    rule(:op => '+', :left => simple(:l), :right => simple(:r)) { l + r }
+  end
+  Trans.new.apply(tree)     # => 3
+</code></pre>
+<p>Cool, isn’t it? To recap: parslet intentionally spits out deep nested hashes, 
+because it also gives you the tool to work with those. Turning the intermediary
+trees into something useful is really easy.</p>
+<h2></h2>
+<h2>Working with Captures</h2>
+<p>What is this <code>simple(symbol)</code> business all about, you might ask.
+Glad you do.</p>
+<h3>Simple captures</h3>
+<p>Transform allows you to specify patterns that have wildcards in them. The
+wildcards match part of the tree, but at the same time capture it for working
+on it in your action block. The wildcard</p>
+<pre class="sh_ruby"><code>
+  simple(:x)
+</code></pre>
+<p>will match any object <span class="caps">BUT</span> hashes or arrays. While this is obviously useful
+for capturing strings, you can also capture other ‘simple’ (as opposed to 
+composed) objects of your own creation. <code>simple(:x)</code> would thus match
+all of these objects:</p>
+<pre class="sh_ruby"><code>
+  "a string"
+  123
+  Foo.new(:some, :class, :instance)
+</code></pre>
+<p>If you think about what you’ll be doing to your intermediary trees, replacing
+leaves with more useful objects, <code>simple</code> really makes good sense, 
+since it will stop you from matching entire subtrees.</p>
+<h3>Matching Repetitions and Sequences</h3>
+<p>Some patterns (like repetitions and sequences) produce arrays of objects as
+result. You can use <code>simple(...)</code> to replace all parts of these
+arrays with your own objects, but you cannot replace the array as a whole. 
+This is the purpose of <code>sequence(symbol)</code>:</p>
+<pre class="sh_ruby"><code>
+  sequence(:x)
+</code></pre>
+<p>will match all of these:</p>
+<pre class="sh_ruby"><code>
+  ['a', 'b', 'c']
+  ['a', 'a', 'a']
+  [Foo.new, Bar.new]
+</code></pre>
+<p>but not</p>
+<pre class="sh_ruby"><code>
+  [{:a => :b}]
+  [['a', 'b']]
+</code></pre>
+<p>Like its smaller brother, <code>sequence</code> is very picky about what it
+consumes and what not. All for the same reasons.</p>
+<h3>Matching entire subtrees</h3>
+<p>So you don’t want to listen and really want that big gun with the foot aiming
+addon. You’ll be needing <code>subtree(symbol)</code>. It always matches. 
+Nuff said.</p>
+<h3>Matching context</h3>
+<p>A match always binds in a context. The context consists of all bindings
+that were previously made. If you reuse the same symbol for two consecutive
+matches within the same pattern, the engine will assume that you want these
+two matched objects to be equal (under <code>==</code>). This allows to 
+specify constraints on your matches that would need code to express otherwise:</p>
+<pre class="sh_ruby"><code>
+  # The following code is an excerpt from example/simple_xml.rb in the distro
+  t.rule(
+    open: {name: simple(:tag)}, 
+    close: {name: simple(:tag)}, 
+    inner: simple(:t)
+  ) { 'verified' }
+</code></pre>
+<p>This replaces <em>matching</em> open and close tags with the word ‘verified’,
+consuming them from the tree and allowing the same rule to match higher up. A
+valid <span class="caps">XML</span> tree will leave only the word ‘verified’ behind, while the parser
+will stop at the problem nodes in invalid trees.</p>
+<h2>Transformation rules</h2>
+<p>In this chapter, we’ll look more closely at transformation rules and the
+different ways they can be laid out in your code.</p>
+<h3>Usage Patterns</h3>
+<p>The way the transformation engine is constructed, there is not one, but three
+ways to use it. Since at least one of those is inconvenient for you, the user,
+I am going to show only the remaining two, Variant 1 that produces an instance
+of the transform for direct use:</p>
+<pre class="sh_ruby"><code>
+  # Variant 1
+  transform = Parslet::Transform.new do
+    rule(...) { ... } 
+    rule(...) { ... } 
+    rule(...) { ... } 
+  end
+  transform.apply(tree)
+</code></pre>
+<p>and Variant 2 that allows constructing the transformation as a class:</p>
+<pre class="sh_ruby"><code>
+  # Variant 2
+  class MyTransform < Parslet::Transform
+    rule(...) { ... } 
+    rule(...) { ... } 
+    rule(...) { ... } 
+  end
+  MyTransform.new.apply(tree)
+</code></pre>
+<p>I guess both have their sweet spot.</p>
+<h3>Action blocks: Two flavors</h3>
+<p>As you might have noticed by now, parslet provides choice as well as nice
+parsers. To recap: Rules have a left side called <em>pattern</em> and a right side 
+called <em>action block</em>:</p>
+<pre class="sh_ruby"><code>
+  rule(PATTERN) {ACTION_BLOCK}
+</code></pre>
+<p>There are two ways of writing action blocks, and the difference might be 
+fundamental to know to you one day. If written like this:</p>
+<pre class="sh_ruby"><code>
+  rule(:foo => simple(:x)) { puts x }
+</code></pre>
+<p>the block will be able to access <code>x</code> as a local variable. This is 
+very convenient and shortens the action code, often to the point of being
+very expressive.</p>
+<p>But there is a <em>big downside</em> to this way of writing things: The action block
+must be executed in the context of some magic instance that has <code>x</code>
+as a local method (aka accessor). You can only have one self at any one time; 
+variable access to the binding of the block isn’t possible inside this kind
+of action blocks:</p>
+<pre class="sh_ruby"><code>
+  y = 12
+  rule(:foo => simple(:x)) { Integer(x) + y }
+</code></pre>
+<p>This will (depending on the context) throw a <code>NameError</code> or a
+<code>NoMethodError</code>.</p>
+<p>But this can be fixed by using the other, less elegant style for action
+blocks:</p>
+<pre class="sh_ruby"><code>
+  y = 12
+  rule(:foo => simple(:x)) { |dictionary| Integer(dictionary[:x]) + y }
+</code></pre>
+<p>In this second flavor, the block gets executed in the context of definition, 
+whatever that was. This means that it can capture and access local variables
+just fine. Access to the bindings (called <code>dictionary</code> here) is 
+more clumsy, but hey, you can’t have your cake and eat it too, I guess. Even 
+though that is a pity.</p>
+<h2>A word on patterns</h2>
+<p>Given the <span class="caps">PORO</span> hash</p>
+<pre class="sh_ruby"><code>
+  { 
+    :dog => 'terrier', 
+    :cat => 'suit' }
+</code></pre>
+<p>one might assume that the following rule matches <code>:dog</code> and
+replaces it by <code>'foo'</code>:</p>
+<pre class="sh_ruby"><code>
+  rule(:dog => 'terrier') { 'foo' }
+</code></pre>
+<p>This is frankly impossible. How would <code>'foo'</code> live besides
+<code>:cat => 'suit'</code> inside the hash? It cannot. This is why hashes are
+either matched completely, cats n’ all, or not at all.</p>
+<p>Transformations are there for one thing: Getting out of the hash/array/slice
+mess parslet creates (on purpose) into the realm of your own beautifully
+crafted <span class="caps">AST</span> classes. Such
+<a href="http://en.wikipedia.org/wiki/Abstract_syntax_tree"><span class="caps">AST</span></a> nodes will generally
+correspond 1:1 to hashes inside your intermediary tree.</p>
+<p>If transformations get you into a mess, remember this simple truth: They have
+been designed for the above purpose. Abusing them is fun (and almost all the
+examples in the project do so) but the mess you get when you do is all yours.</p>
+<p>If you are really desperate, try to look at the example in <a href="get-started.html">Get Started</a> or at the parser in the sample project
+<a href="https://github.com/kschiess/wt">wt</a>. Imitating them would be a good first step. And if all else fails, we’re there for you, see the ‘Contact’ section in <a href="contribute.html">Contribute</a>.</p>
+<h2>Summary</h2>
+<p>This concludes this (three part) introduction to parslet and leaves you with a
+good knowledge of most tricky parts. If you are missing some detail, maybe
+you can find it in the texts referenced <a href="documentation.html">here</a>? There is 
+also an entire page on the tricks useful in practice here: <a href="tricks.html">Tricks</a>.</p>
+<p>If not, please tell us about it. We’ll include it in this documentation in no 
+time.</p></div>

+        <h1>Tricks for common situations</h1><h2>Matching <span class="caps">EOF</span> (End Of File)</h2>
+<p>Ahh Sir, you’ll be needin what us parsers call <em>epsilon</em>:</p>
+<pre class="sh_ruby"><code>
+  rule(:eof) { any.absent? }
+</code></pre>
+<p>Of course, most of us don’t use this at all, since any parser has <span class="caps">EOF</span> as
+implicit last input.</p>
+<h2>Matching Strings Case Insensitive</h2>
+<p>Parslet is fully hackable: You can use code to create parsers easily. Here’s
+how I would match a string in case insensitive manner:</p>
+<pre class="sh_ruby"><code title="case insensitive match">
+  def stri(str)
+    key_chars = str.split(//)
+    key_chars.
+      collect! { |char| match["#{char.upcase}#{char.downcase}"] }.
+      reduce(:>>)
+  end
+
+  # Constructs a parser using a Parser Expression Grammar 
+  stri('keyword').parse "kEyWoRd"     # => "kEyWoRd"@0
+</code></pre>
+<h2>Testing</h2>
+<p>Parslet helps you to create parsers that are in turn created out of many small
+parsers. It is really turtles all the way down. Imagine you have a complex 
+parser:</p>
+<pre class="sh_ruby"><code>
+  class ComplexParser < Parslet::Parser
+    root :lots_of_stuff
+  
+    rule(:lots_of_stuff) { ... }
+  
+    # and many lines later: 
+    rule(:simple_rule) { str('a') }
+  end
+</code></pre>
+<p>Also imagine that the parser (as a whole) fails to consume the ‘a’ that 
+<code>simple_rule</code> is talking about.</p>
+<p>This kind of problem can very often be fixed by bisecting it into two possible
+problems. Either:</p>
+<ol>
+	<li>the <code>lots_of_stuff</code> rule somehow doesn’t place <code>simple_rule</code>
+  in the right context or</li>
+	<li>the <code>simple_rule</code> simply (hah!) fails to match its input.</li>
+</ol>
+<p>I find it very useful in this situation to eliminate 2. from our options:</p>
+<pre class="sh_ruby"><code title="rspec">
+  require 'rspec'
+  require 'parslet/rig/rspec'
+  
+  class ComplexParser < Parslet::Parser
+    rule(:simple_rule) { str('a') }
+  end
+
+  describe ComplexParser  do
+    let(:parser) { ComplexParser.new }
+    context "simple_rule" do
+      it "should consume 'a'" do
+        parser.simple_rule.should parse('a')
+      end 
+    end
+  end
+  
+  RSpec::Core::Runner.run([])
+</code></pre>
+<p>Output is: 
+<pre class="output"></p>
+<p>Example::ComplexParser
+  simple_rule
+    should consume ‘a’</p>
+<p>Finished in 0.00115 seconds
+1 example, 0 failures
+</pre></p>
+<p>Parslet parsers have one method per rule. These methods return valid parsers
+for a subset of your grammar.</p>
+<h2>Error reports</h2>
+<p>If your grammar fails and you’re aching to know why, here’s a bit of exception
+handling code that will help you out:</p>
+<pre class="sh_ruby"><code title="exception handling">
+  parser = str('foo')
+  begin
+    parser.parse('bar')
+  rescue Parslet::ParseFailed => error
+    puts error.cause.ascii_tree
+  end
+</code></pre>
+<p>This should print something akin to:</p>
+<pre class="output"> 
+Expected "foo", but got "bar" at line 1 char 1.
+</pre>
+<p>These error reports are probably the fastest way to know exactly where you
+went wrong (or where your input is wrong, which is aequivalent).</p>
+<p>And since this is such a common idiom, we provide you with a shortcut: to
+get the above, just:</p>
+<pre class="sh_ruby"><code>
+require 'parslet/convenience'
+parser.parse_with_debug(input)
+</code></pre>
+<h3>Reporter engines</h3>
+<p>Note that there is currently not one, but two error reporting engines! The 
+default engine will report errors in a structure that looks exactly like the
+grammar structure:</p>
+<pre class="sh_ruby"><code title="error reporter 1">
+  class P < Parslet::Parser
+    root(:body)
+    rule(:body) { elements }
+    rule(:elements) { (call | element).repeat(2) }
+    rule(:element) { str('bar') }
+    rule(:call) { str('baz') >> str('()') }
+  end
+  
+  begin
+    P.new.parse('barbaz')
+  rescue Parslet::ParseFailed => error
+    puts error.cause.ascii_tree
+  end
+</code></pre>
+<p>Outputs:</p>
+<pre class="output"> 
+Expected at least 2 of CALL / ELEMENT at line 1 char 1.
+`- Expected one of [CALL, ELEMENT] at line 1 char 4.
+   |- Failed to match sequence ('baz' '()') at line 1 char 7.
+   |  `- Premature end of input at line 1 char 7.
+   `- Expected "bar", but got "baz" at line 1 char 4.
+</pre>
+<p>Let’s switch out the ‘grammar structure’ engine (called ‘<code>Tree</code>’)
+with the ‘deepest error position’ engine:</p>
+<pre class="sh_ruby"><code title="error reporter 2">
+  class P < Parslet::Parser
+    root(:body)
+    rule(:body) { elements }
+    rule(:elements) { (call | element).repeat(2) }
+    rule(:element) { str('bar') }
+    rule(:call) { str('baz') >> str('()') }
+  end
+  
+  begin
+    P.new.parse('barbaz', reporter: Parslet::ErrorReporter::Deepest.new)
+  rescue Parslet::ParseFailed => error
+    puts error.cause.ascii_tree
+  end
+</code></pre>
+<p>Outputs:</p>
+<pre class="output"> 
+Expected at least 2 of CALL / ELEMENT at line 1 char 1.
+`- Expected one of [CALL, ELEMENT] at line 1 char 4.
+   |- Failed to match sequence ('baz' '()') at line 1 char 7.
+   |  `- Premature end of input at line 1 char 7.
+   `- Premature end of input at line 1 char 7.
+</pre>
+<p>The <code>'Deepest'</code> position engine will store errors that are the
+farthest into the input. In some examples, this produces more readable output
+for the end user.</p>
+<h2>Line numbers from parser output</h2>
+<p>A traditional parser would parse and then perform several checking phases,
+like for example verifying all type constraints are respected in the input.
+During this checking phase, you will most likely want to report screens full
+of type errors back to the user (‘cause that’s what types are for, right?).
+Now where did that ‘int’ come from?</p>
+<p>Parslet gives you slices (Parslet::Slice) of input as part of your tree. These
+are essentially strings with line numbers. Here’s how to print that error
+message:</p>
+<pre class="sh_ruby"><code>
+  # assume that type == "int"@0 - a piece from your parser output
+  line, col = type.line_and_column
+  puts "Sorry. Can't have #{type} at #{line}:#{col}!"
+</code></pre></div>

+title: Get Started
+---
+
+Let's develop a small language that allows for simple computation together. 
+Here's a valid input file for that language: 
+
+<pre class="sh_ruby"><code> 
+  puts(1 + 2)
+  puts(4 + 2)
+</code></pre>
+
+To install the parslet library, please do a 
+
+<pre><code> 
+  gem install parslet
+</code></pre>
+
+Now let's write the first part of our parser. For now, we'll just recognize
+simple numbers like '1' or '42'.
+
+<pre class="sh_ruby"><code title="mini_parser"> 
+  require 'parslet' 
+
+  class Mini < Parslet::Parser
+    rule(:integer) { match('[0-9]').repeat(1) }
+    root(:integer)
+  end
+
+  Mini.new.parse("132432")  # => "132432"@0
+</code></pre>
+
+Running this example will print "132432 at 0". Congratulations! You just have
+written your first parser. Running it on the input '<code>puts(1)</code>' will
+not work yet. Let's see what happens in case of a failure:
+
+<pre class="sh_ruby"><code> 
+  Mini.new.parse("puts(1)") # raises Parslet::ParseFailed
+</code></pre>
+
+Here's the error message provided by that exception: "Expected at least 1 of
+[0-9] at line 1 char 1." parslet tries to find a number there, but can't find
+one.
+
+There are just two lines to the definition of this parser, let's go through
+them:
+
+<pre class="sh_ruby"><code> 
+  rule(:integer) { match('[0-9]').repeat(1) }
+</code></pre>
+
+<code>rule</code> lets you create a new parser rule. Inside the block of that
+<code>:integer</code> rule, you find <code>match('[0-9]').repeat(1)</code>.
+This says: "match a character that is in the range <code>0-9</code>, then
+match any number of those, but at least match one."
+
+<pre class="sh_ruby"><code> 
+  root(:integer)
+</code></pre>
+
+That second line just says: Start parsing at the rule called
+<code>:integer</code>.
+
+h2. Addition
+
+Let's go for simple addition. We'll have to allow for spaces in our input,
+since those help make code readable. 
+
+<pre class="sh_ruby"><code> 
+  rule(:space)  { match('\s').repeat(1) }
+  rule(:space?) { space.maybe }
+</code></pre>
+
+Two things are new here: (and both in the second line)
+
+* you can use ('call') other rules in your rules 
+* <code>.maybe</code>, the same as <code>.repeat(0,1)</code>[1], indicating 
+  that the thing before it is maybe present once in the input.
+  
+Essentially, you can think about parslet rules as instructing Ruby to "parse
+this" and "parse that". Calling other rules can be looked at in the same way;
+you tell Ruby to go off, parse that subrule and then come back with the
+results. This helps when thinking about rule recursion. For example, a
+self-recursive rule like this one will of course create an endless loop:
+
+<pre class="sh_ruby"><code> 
+  rule(:infinity) {
+    infinity >> str(';')
+  }
+</code></pre>
+
+Even though infinity seems to be delimited by ';', in reality, infinity is
+very long, especially towards the end. There is no way of knowing for the
+parser when to stop processing <code>infinity</code> and start reading
+semicolons. Ergo, we need to make sure we talk about concrete items that
+consume input first, and then do recursion. This way we ensure that our
+grammar terminates, since in a way, it is like a normal program.
+
+Here's the full parser:
+
+<pre class="sh_ruby"><code title="full_parser">  
+  class Mini < Parslet::Parser
+    rule(:integer)    { match('[0-9]').repeat(1) >> space? }
+  
+    rule(:space)      { match('\s').repeat(1) }
+    rule(:space?)     { space.maybe }
+  
+    rule(:operator)   { match('[+]') >> space? }
+  
+    rule(:sum)        { integer >> operator >> expression }
+    rule(:expression) { sum | integer }
+
+    root :expression
+  end
+
+  def parse(str)
+    mini = Mini.new
+  
+    mini.parse(str)
+  rescue Parslet::ParseFailed => failure
+    puts failure.cause.ascii_tree
+  end
+
+  parse "1 + 2 + 3"  # => "1 + 2 + 3"@0
+  parse "a + 2"      # fails, see below
+</code></pre>
+
+As you can see, the parser got decorated with the <code>space?</code> idiom.
+Every atom of our language consumes the space right after it. This is a useful
+convention that makes top level rules (the important ones) look cleaner.
+
+Note also the addition of <code>:operator</code>, <code>:sum</code> and
+<code>:expression</code>. The runner code has been extended a bit, so as to
+throw nice explanations of what went wrong when a parse failure is
+encountered. Running the code on '<code>a + 2</code>' for example outputs:
+
+<pre class="output">  
+Expected one of [SUM, INTEGER] at line 1 char 1.
+|- Failed to match sequence (INTEGER OPERATOR EXPRESSION) at line 1 char 1.
+|  `- Failed to match sequence ([0-9]{1, } SPACE?) at line 1 char 1.
+|     `- Expected at least 1 of [0-9] at line 1 char 1.
+|        `- Failed to match [0-9] at line 1 char 1.
+`- Failed to match sequence ([0-9]{1, } SPACE?) at line 1 char 1.
+   `- Expected at least 1 of [0-9] at line 1 char 1.
+      `- Failed to match [0-9] at line 1 char 1.
+</pre>
+
+This is what parslet calls an <code>#error_tree</code>. Not only the output of
+your parser, but also its grammar is constructed like a tree. When things go
+wrong, every branch of the tree has its own reasons for not accepting a given
+input. The <code>#cause</code> method returns those reasons.
+
+Our grammar has essentially two branches, <code>SUM</code> and
+<code>INTEGER</code>. Can you see why all rules expect a number as the first
+character?
+
+h2. Tree output (and what to do about it)
+
+But if we leave the negative examples for a second; what happens if the parse
+succeeds? It turns out, not much: 
+
+<pre class="sh_ruby"><code>
+  parse "1 + 2 + 3"  # => "1 + 2 + 3"@0
+</code></pre>
+
+The only notable difference between input and output is that the output has an
+extra '@0' appended to it. This is related to line number tracking and will be
+explained later on (or you can skip ahead and look up
+<code>Parslet::Slice</code>).
+
+The code we now have parses the input successfully, but doesn't do much else. 
+Parslet hasn't got its own opinion on what to do with your input. By default, 
+it will just play it back to you. But parslet provides also a method of 
+structuring its output: 
+
+<pre class="sh_ruby"><code title="output_samples"> 
+  # Without structure: just strings.
+  str('ooo').parse('ooo')                           # => "ooo"@0
+  str('o').repeat.parse('ooo')                      # => "ooo"@0
+
+  # Added structure: .as(...)
+  str('ooo').as(:ex1).parse('ooo')                  # => {:ex1=>"ooo"@0}
+  
+  long = str('o').as(:ex2a).repeat.as(:ex2b).parse('ooo')  
+  long # => {:ex2b=>[{:ex2a=>"o"@0}, {:ex2a=>"o"@1}, {:ex2a=>"o"@2}]}
+</code></pre>
+
+You get to name things the way you want! This is also free. Seriously: parslet
+requires you to add all the structure to its output. Annotate important parts
+of your grammar with <code>.as(:symbol)</code> and get back a tree-like
+structure composed of hashes (sequence), arrays (repetition) and strings (like
+we had initially).
+
+Once you start naming things, you'll notice that what you don't name,
+disappears. Parslet assumes that _what you don't name is unimportant_.
+
+<pre class="sh_ruby"><code title="inline_parser"> 
+parser =  str('a').as(:a) >> str(' ').maybe >> 
+          str('+').as(:o) >> str(' ').maybe >> 
+          str('b').as(:b)
+parser.parse('a + b') # => {:a=>"a"@0, :o=>"+"@2, :b=>"b"@4}
+</code></pre>
+
+Think of this like using a highlighter on your input: What is there not to
+like about neon yellow?
+
+h2. Making the parser complete
+
+Let's look at the complete parser definition that also allows for function
+calls:
+
+<pre class="sh_ruby"><code title="full_parser"> 
+class MiniP < Parslet::Parser
+  # Single character rules
+  rule(:lparen)     { str('(') >> space? }
+  rule(:rparen)     { str(')') >> space? }
+  rule(:comma)      { str(',') >> space? }
+
+  rule(:space)      { match('\s').repeat(1) }
+  rule(:space?)     { space.maybe }
+
+  # Things
+  rule(:integer)    { match('[0-9]').repeat(1).as(:int) >> space? }
+  rule(:identifier) { match['a-z'].repeat(1) }
+  rule(:operator)   { match('[+]') >> space? }
+  
+  # Grammar parts
+  rule(:sum)        { integer.as(:left) >> operator.as(:op) >> expression.as(:right) }
+  rule(:arglist)    { expression >> (comma >> expression).repeat }
+  rule(:funcall)    { identifier.as(:funcall) >> lparen >> arglist.as(:arglist) >> rparen }
+  
+  rule(:expression) { funcall | sum | integer }
+  root :expression
+end
+
+require 'pp'
+pp MiniP.new.parse("puts(1 + 2 + 3, 45)")
+</code></pre>
+
+That's really all there is to it -- our language is a really simple language. 
+When fed with a string like '<code>puts(1 + 2 + 3, 45)</code>, our parser outputs
+the following: 
+
+<pre class="output"> 
+{:funcall=>"puts"@0,
+ :arglist=>
+  [{:left=>{:int=>"1"@5},
+    :op=>"+ "@7,
+    :right=>{:left=>{:int=>"2"@9}, :op=>"+ "@11, :right=>{:int=>"3"@13}}},
+   {:int=>"45"@16}]}
+</code></pre>
+
+Parslet calls this the _intermediary tree_. There are three types of nodes in
+this tree:
+
+* *Hashes*: a node that has named subtrees
+* *Arrays*: a node storing a collection of sub-nodes
+* *Strings* are the leaves, containing the _accepted source_
+
+The format of this tree is easy to work with and to read. Here's what the
+above tree would look like as a graphic:
+
+!images/ast.png!
+
+h2. Where to go from here: An Interpreter
+
+As nice as the format above is for printing and looking at - it may be
+difficult at times to get the information out of it again. Let's look at how
+to transform the tree:
+
+<pre class="sh_ruby"><code> 
+class SimpleTransform < Parslet::Transform
+  rule(funcall: 'puts', arglist: sequence(:args)) {
+    "puts(#{args.inspect})"
+  }
+  # ... other rules
+end
+
+tree = {funcall: 'puts', arglist: [1,2,3]}
+SimpleTransform.new.apply(tree) # => "puts([1, 2, 3])"
+</code></pre>
+
+Transformation is an entire topic by itself; this will be covered in detail
+"later on":transform.html. To whet your appetite, let me just give you a few
+teasers:
+
+* Transformations match portions of your tree at any depth, replacing them
+  with whatever you decide.
+* In addition to <code>sequence(sym)</code>, there is also
+  <code>simple(sym)</code> and <code>subtree(sym)</code>. Those match simple
+  strings and entire subtrees respectively. Caution with the latter.
+
+Here's how you would write a somewhat classical interpreter for our little 
+language by using a transformation. Note that from this point on, there is
+not one way to go about this, but thousands; you are really free (and on
+your own): 
+
+<pre class="sh_ruby"><code title="putting it all together">

+
+That's a bunch of code for printing <code>[1, 2, 3, 9]</code>. Welcome to the

+
+[1] As far as parsing goes. There is a subtle difference between
+<code>#repeat(0,1)</code> and <code>#maybe</code>. Can you figure it out?

+
+A small Ruby library for constructing parsers in the
+"PEG":http://en.wikipedia.org/wiki/Parsing_expression_grammar (Parsing
+Expression Grammar) fashion.
+
+
+Parslet makes developing complex parsers easy. It does so by
+
+* providing the best *error reporting* possible
+* *not generating* reams of code for you to debug
+
+Parslet takes the long way around to make *your job* easier. It allows for
+incremental language construction. Often, you start out small, implementing
+the atoms of your language first; _parslet_ takes pride in making this
+possible.

+title: Overview
+---
+
+Parslet is a library with a clear philosophy: It makes parser writing easy and
+testable. On top of that, it provides understandable error messages ("General
+Protection Fault") to you, the language writer. In extension, you will
+hopefully manage to provide good error messages to your users. Together, we 
+can create a better world!
+
+Traditional texts on the subject will have you write a compiler or interpreter
+for a language in several stages: 
+
+* Parsing or Lexing/Parsing
+* Abstract Syntax Tree construction
+* Optimization and checking of the tree
+* Generation of code / Execution
+
+This library will be good for the first two stages only. After that, you'll
+be on your own. 
+
+The parsing step has literally been implemented by hundreds (thousands) of
+clever people; No lack of alternatives. Even in Ruby, you'll have the choice 
+among a handful of libraries. There's a distinction to make on this level as
+well: 
+
+*LRk parsers and related fields* Parsers in this class use a lexical analyzer
+(a _lexer_ ) to transform the input text into tokens (_tokenizing_ ). They
+then check if your stream of tokens has a corresponding tree that conforms to
+the grammar. Most of these parsers allow grammars that are ambiguous and will
+provide a mechanism for resolving the arising ambiguities. These are the
+earliest parser generators and the most widely used (_yacc_, _bison_, ...) --
+chances are, you'll have more than one of these libraries installed on your
+system.
+
+*PEG or packrat parsers* Parsers in this class are based on a slightly more
+modern algorithm, which translates what one does when writing a parser by hand
+in top-down fashion. This is what we programmers do all over, methods calling
+methods - and its also (grossly) what these parsers do to recognize input.
+Left recursion is impossible to express in these grammars. No lexers are
+required - lexical tokenizing and parsing are one single step. Ruby has
+several implementations of this algorithm in library form:
+"Treetop":http://github.com/nathansobo/treetop,
+"Citrus":http://github.com/mjijackson/citrus,
+"rsec":http://wiki.github.com/luikore/rsec/ and of course
+"Parslet":http://kschiess.github.com/parslet.
+
+All of these generators are different in small ways; yet most implement common
+patterns and provide almost identical APIs. We believe this is an error:
+choice is good, but there should be visible attributes distinguishing the
+choices.
+
+Parslet is not like the others, in fact it is radically different on some
+key elements. 
+
+h2. Writing a language
+
+Whether you write a language for a configuration file or a new computer
+language (the holy grail), the steps are always the same: 
+
+# Create a grammar: _What should be legal syntax?_
+# Annotate the grammar: _What is important data?_
+# Create a transformation: _How do I want to work with that data?_
+
+The creation of grammars and the various concepts that are associated are treated
+in "Parslet::Parser":parser.html.
+
+Transformation of the resulting intermediary tree is treated in
+"Parslet::Transform":transform.html
+

+title: Parser construction
+---
+
+A parser is nothing more than a class that derives from
+<code>Parslet::Parser</code>. The simplest parser that one could write would
+look like this: 
+
+<pre class="sh_ruby"><code>
+  class SimpleParser < Parslet::Parser
+    rule(:a_rule) { str('simple_parser') }
+    root(:a_rule)
+  end
+</code></pre>
+
+The language recognized by this parser is simply the string "simple_parser". 
+Parser rules do look a lot like methods and are defined by 
+
+<pre class="sh_ruby"><code>
+  rule(name) { definition_block }
+</code></pre>
+
+Behind the scenes, this really defines a method that returns whatever you 
+return from it. 
+
+Every parser has a root. This designates where parsing should start. It is like
+an entry point to your parser. With a root defined like this: 
+
+<pre class="sh_ruby"><code>
+  root(:my_root)
+</code></pre>
+
+you create a <code>#parse</code> method in your parser that will start parsing
+by calling the <code>#my_root</code> method. You'll also have a <code>#root</code>
+(instance) method that is an alias of the root method. The following things are
+really one and the same: 
+
+<pre class="sh_ruby"><code>
+  SimpleParser.new.parse(string)
+  SimpleParser.new.root.parse(string)
+  SimpleParser.new.a_rule.parse(string)
+</code></pre>
+
+Knowing these things gives you a lot of flexibility; I'll explain why at the
+end of the chapter. For now, just let me point out that because all of this is
+Ruby, your favorite editor will syntax highlight parser code just fine.
+
+h2. Atoms: The inside of a parser
+
+h3. Matching strings of characters
+
+A parser is constructed from parser atoms (or parslets, hence the name). The
+atoms are what appear inside your rules (and maybe elsewhere). We've already
+encountered an atom, the string atom: 
+
+<pre class="sh_ruby"><code>
+  str('simple_parser')
+</code></pre>
+
+This returns a <code>Parslet::Atoms::Str</code> instance. These parser atoms
+all derive from <code>Parslet::Atoms::Base</code> and have essentially just
+one method you can call: <code>#parse</code>. So this works: 
+
+<pre class="sh_ruby"><code title="parser atoms">
+  str('foobar').parse('foobar') # => "foobar"@0
+</code></pre>
+
+The atoms are small parsers that can recognize languages and throw errors, just
+like real <code>Parslet::Parser</code> subclasses. 
+
+h3. Matching character ranges
+
+The second parser atom you will have to know about allows you to match
+character ranges: 
+
+<pre class="sh_ruby"><code>
+  match('[0-9a-f]')
+</code></pre>
+
+The above atom would match the numbers zero through nine and the letters 'a' 
+to 'f' - yeah, you guessed right - hexadecimal numbers for example. The inside
+of such a match parslet is essentially a regular expression that matches 
+a single character of input. Because we'll be using ranges so much with 
+<code>#match</code> and because typing ('[]') is tiresome, here's another way
+to write the above <code>#match</code> atom:
+
+<pre class="sh_ruby"><code>
+  match['0-9a-f']
+</code></pre>
+
+Character matches are instances of <code>Parslet::Atoms::Re</code>. Here are 
+some more examples of character ranges: 
+
+<pre class="sh_ruby"><code>
+  match['[:alnum:]']      # letters and numbers
+  match['\\n']            # newlines
+  match('\\w')            # word characters
+  match('.')              # any character
+</code></pre>
+
+h3. The wild wild <code>#any</code>
+
+The last example above corresponds to the regular expression <code>/./</code> that matches
+any one character. There is a special atom for that: 
+
+<pre class="sh_ruby"><code>
+  any 
+</code></pre>
+
+h2. Composition of Atoms
+
+These basic atoms can be composed to form complex grammars. The following
+few sections will tell you about the various ways atoms can be composed.
+
+h3. Simple Sequences
+
+Match 'foo' and then 'bar': 
+
+<pre class="sh_ruby"><code>
+  str('foo') >> str('bar')    # same as str('foobar')
+</code></pre>
+
+Sequences correspond to instances of the class
+<code>Parslet::Atoms::Sequence</code>.
+
+h3. Repetition and its Special Cases
+
+To model atoms that can be repeated, you should use <code>#repeat</code>: 
+
+<pre class="sh_ruby"><code>
+  str('foo').repeat
+</code></pre>
+
+This will allow foo to repeat any number of times, including zero. If you
+look at the signature for <code>#repeat</code> in <code>Parslet::Atoms::Base</code>, 
+you'll see that it has really two arguments: _min_ and _max_. So the following
+code all makes sense: 
+
+<pre class="sh_ruby"><code>
+  str('foo').repeat(1)      # match 'foo' at least once
+  str('foo').repeat(1,3)    # at least once and at most 3 times
+  str('foo').repeat(0, nil) # the default: same as str('foo').repeat
+</code></pre>
+
+Repetition has a special case that is used frequently: Matching something
+once or not at all can be achieved by <code>repeat(0,1)</code>, but also 
+through the prettier: 
+
+<pre class="sh_ruby"><code>
+  str('foo').maybe          # same as str('foo').repeat(0,1)
+</code></pre>
+
+These all map to <code>Parslet::Atoms::Repetition</code>. Please note this
+little twist to <code>#maybe</code>:
+
+<pre class="sh_ruby"><code title="maybes twist">
+  str('foo').maybe.as(:f).parse('')         # => {:f=>nil}
+  str('foo').repeat(0,1).as(:f).parse('')   # => {:f=>[]}
+</code></pre>
+
+The 'nil'-value of <code>#maybe</code> is nil. This is catering to the
+intuition that <code>foo.maybe</code> either gives me <code>foo</code> or
+nothing at all, not an empty array. But have it your way!
+
+h3. Alternation
+
+The most important composition method for grammars is alternation. Without
+it, your grammars would only vary in the amount of things matched, but not
+in content. Here's how this looks: 
+
+<pre class="sh_ruby"><code>
+  str('foo') | str('bar')   # matches 'foo' OR 'bar'
+</code></pre>
+
+This reads naturally as "'foo' or 'bar'". 
+
+h3. Operator precedence
+
+The operators we have chosen for parslet atom combination have the operator
+precedence that you would expect. No parenthesis are needed to express
+alternation of sequences:
+
+<pre class="sh_ruby"><code>
+  str('s') >> str('equence') | 
+    str('se') >> str('quence')
+</code></pre>
+
+h3. And more
+
+Parslet atoms are not as pretty as Treetop atoms. There you go, we said it. 
+However, there seems to be a different kind of aesthetic about them; they 
+are pure Ruby and integrate well with the rest of your environment. Have a 
+look at this: 
+
+<pre class="sh_ruby"><code>
+  # Also consumes the space after important things like ';' or ':'. Call this
+  # giving the character you want to match as argument: 
+  #
+  #   arg >> (spaced(',') >> arg).repeat
+  #
+  def spaced(character)
+    str(character) >> match["\s"]
+  end
+</code></pre>
+
+or even this: 
+
+<pre class="sh_ruby"><code>
+  # Turns any atom into an expression that matches a left parenthesis, the 
+  # atom and then a right parenthesis.
+  #
+  #   bracketed(sum)
+  #
+  def bracketed(atom)
+    spaced('(') >> atom >> spaced(')')
+  end
+</code></pre>
+
+You might say that because parslet is just plain old Ruby objects itself (PORO
+(tm)), it allows for very tight code. Module inclusion, class inheritance, ...
+all your tools should work well with parslet.
+
+h2. Tree construction
+
+By default, parslet will just echo back to you the strings you feed into it. 
+Parslet will not generate a parser for you and neither will it generate your
+abstract syntax tree for you. The method <code>#as(name)</code> allows you
+to specify exactly how you want your tree to look like: 
+
+<pre class="sh_ruby"><code title="using as">
+  str('foo').parse('foo')             # => "foo"@0
+  str('foo').as(:bar).parse('foo')    # => {:bar=>"foo"@0}
+</code></pre>
+
+So you think: <code>#as(name)</code> allows me to create a hash, big deal.
+That's not all. You'll notice that annotating everything that you want to keep
+in your grammar with <code>#as(name)</code> autocreates a sensible tree
+composed of hashes and arrays and strings. It's really somewhat magic: Parslet
+has a set of clever rules that merge the annotated output from your atoms into
+a tree. Here are some more examples, with the atom on the left and the resulting
+tree (assuming a successful parse) on the right: 
+
+<pre class="sh_ruby"><code>
+  # Normal strings just map to strings
+  str('a').repeat                         "aaa"@0                                 
+
+  # Arrays capture repetition of non-strings
+  str('a').repeat.as(:b)                  {:b=>"aaa"@0}                           
+  str('a').as(:b).repeat                  [{:b=>"a"@0}, {:b=>"a"@1}, {:b=>"a"@2}] 
+
+  # Subtrees get merged - unlabeled strings discarded
+  str('a').as(:a) >> str('b').as(:b)      {:a=>"a"@0, :b=>"b"@1}                  
+  str('a') >> str('b').as(:b) >> str('c') {:b=>"b"@1}                             
+
+  # #maybe will return nil, not the empty array
+  str('a').maybe.as(:a)                   {:a=>"a"@0}                             
+  str('a').maybe.as(:a)                   {:a=>nil}
+</code></pre>
+
+h2. Capturing input
+
+_Advanced reading material - feel free to skip this._
+
+Sometimes a parser needs to match against something that was already matched
+against. Think about Ruby heredocs for example: 
+
+<pre class="sh_ruby"><code>
+  str = <-HERE
+    This is part of the heredoc.
+  HERE
+</code></pre>
+
+The key to matching this kind of document is to capture part of the input
+first and then construct the rest of the parser based on the captured part.
+This is what it looks like in its simplest form: 
+
+<pre class="sh_ruby"><code>
+  match['ab'].capture(:capt) >>               # create the capture
+    dynamic { |s,c| str(c.captures[:capt]) }  # and match using the capture
+</code></pre>
+
+This parser matches either 'aa' or 'bb', but not mixed forms 'ab' or 'ba'. The
+last sample introduced two new concepts for this kind of complex parser: the 
+<code>#capture(name)</code> method and the <code>dynamic { ... }</code> code
+block. 
+
+Appending <code>#capture(name)</code> to any parser will capture that parsers
+result in the captures hash in the parse context. If and only if the parser
+<code>match['ab']</code> succeeds, it stores either 'a' or 'b' in 
+<code>context.captures[:capt]</code>.
+
+The only way to get at that hash during the parse process is in a
+<code>dynamic { ... }</code> code block. (for reasons that are out of the
+scope of this document) In such a block, you can: 
+
+<pre class="sh_ruby"><code>
+  dynamic { |source, context|
+    # construct parsers by using randomness
+    rand < 0.5 ? str('a') : str('b')
+    
+    # Or by using context information 
+    str( context.captures[:capt] )
+    
+    # Or by .. doing other kind of work (consumes 100 chars and then 'a')
+    source.consume(100)
+    return str('a')
+  }
+</code></pre>
+
+h3. Scopes
+
+What if you want to parse heredocs contained within heredocs? It's turtles all
+the way down, after all. To be able to remember what string was used to
+construct the outer heredoc, you would use the <code>#scope { ... }</code>
+block that was introduced in parslet 1.5. Like opening a Ruby block, it allows
+you to capture results (assign values to variables) to the same names you've 
+already used in outer scope - _without destroying the outer scopes values for 
+these captures!_.
+
+Here's an example for this: 
+<pre class="sh_ruby"><code>
+  str('a').capture(:a) >> scope { str('b').capture(:a) } >> 
+    dynamic { |s,c| str(c.captures[:a]) }
+</code></pre>
+
+This parses 'aba' - if you understand that, you understand scopes and
+captures. Congrats.
+
+h2. And more
+
+Now you know exactly how to create parsers using Parslet. Your parsers
+will output intricate structures made of endless arrays, complex hashes and 
+a few string leftovers. But your programming skills fail you when you try
+to put all this data to use. Selecting keys upon keys in hash after hash, you
+feel like a cockroach that has just read Kafka's works. This is no fun. This 
+is not what you signed up for. 
+
+Time to introduce you to "Parslet::Transform":transform.html and its workings.

+title: Transformation
+---
+
+Parslet parsers output deep nested hashes. Those are nice for printing, but 
+hard to work with. The structure of the nested hashes is determined by the
+grammar and can thus vary largely. Testing for the presence of individual 
+keys would produce code that is hard to read and maintain. 
+
+This is why parslet also comes with a hash transformation engine. To construct
+such a transform, you have to derive from <code>Parslet::Transform</code>: 
+
+<pre class="sh_ruby"><code title="simple transform">
+  class MyTransform < Parslet::Transform
+    rule('a') { 'b' }
+  end
+  MyTransform.new.apply('a') # => "b"
+</code></pre>
+
+This is a transformation that replaces all 'a's with 'b's. A transformation
+rule has two parts: A *pattern* (here: <code>'a'</code>) and an *action block*
+(<code>{ 'b' }</code>).
+
+The engine will go through the input and traverse the tree in depth-first
+post-order fashion. This means that for a given tree node, it will first visit
+the children and only then look at the node itself. While traversing, all
+rules are tested in the order in which they are defined. If a rule matches, the
+corresponding tree is _replaced_ by whatever the action block returns.
+
+Here's another way of saying the same thing, perhaps more in line with what
+you need as a user of Parslet: <code>Parslet::Transform</code> is what allows
+you to transform the PORO-trees magically into a real abstract syntax tree.
+The rule definitions are the futuristic nano-machines that act on tree leaves
+first, eating them away and replacing them with contraptions of your own
+design. Here's how that might look like in Ruby:
+
+<pre class="sh_ruby"><code title="poro magic">
+  tree = {:left => {:int => '1'}, 
+          :op   => '+', 
+          :right => {:int => '2'}}
+        
+  class Trans < Parslet::Transform
+    rule(:int => simple(:x)) { Integer(x) }
+  end
+  Trans.new.apply(tree)     # => {:left=>1, :op=>"+", :right=>2}
+</code></pre>
+
+You can start thinking about the leaves first, transforming those <code>:int
+=> '1'</code> into real Ruby integers. This incremental (test driven!)
+approach will prevent your intermediary tree from turning into grey goo
+from too many nano-machines. Rules should in general be simple and transform
+a small part of the tree into a more useful variant. Turns out that if we were
+looking for an interpreter, one more rule will give us evaluation: 
+
+<pre class="sh_ruby"><code title="building up">
+  tree = {:left => {:int => '1'}, 
+          :op   => '+', 
+          :right => {:int => '2'}}
+
+  class Trans < Parslet::Transform
+    rule(:int => simple(:x)) { Integer(x) }
+    rule(:op => '+', :left => simple(:l), :right => simple(:r)) { l + r }
+  end
+  Trans.new.apply(tree)     # => 3
+</code></pre>
+
+Cool, isn't it? To recap: parslet intentionally spits out deep nested hashes, 
+because it also gives you the tool to work with those. Turning the intermediary
+trees into something useful is really easy. 
+
+h2. 
+
+h2. Working with Captures
+
+What is this <code>simple(symbol)</code> business all about, you might ask.
+Glad you do.
+
+h3. Simple captures
+
+Transform allows you to specify patterns that have wildcards in them. The
+wildcards match part of the tree, but at the same time capture it for working
+on it in your action block. The wildcard
+
+<pre class="sh_ruby"><code>
+  simple(:x)
+</code></pre>
+
+will match any object BUT hashes or arrays. While this is obviously useful
+for capturing strings, you can also capture other 'simple' (as opposed to 
+composed) objects of your own creation. <code>simple(:x)</code> would thus match
+all of these objects: 
+
+<pre class="sh_ruby"><code>
+  "a string"
+  123
+  Foo.new(:some, :class, :instance)
+</code></pre>
+
+If you think about what you'll be doing to your intermediary trees, replacing
+leaves with more useful objects, <code>simple</code> really makes good sense, 
+since it will stop you from matching entire subtrees. 
+
+h3. Matching Repetitions and Sequences
+
+Some patterns (like repetitions and sequences) produce arrays of objects as
+result. You can use <code>simple(...)</code> to replace all parts of these
+arrays with your own objects, but you cannot replace the array as a whole. 
+This is the purpose of <code>sequence(symbol)</code>: 
+
+<pre class="sh_ruby"><code>
+  sequence(:x)
+</code></pre>
+
+will match all of these: 
+
+<pre class="sh_ruby"><code>
+  ['a', 'b', 'c']
+  ['a', 'a', 'a']
+  [Foo.new, Bar.new]
+</code></pre>
+
+but not
+
+<pre class="sh_ruby"><code>
+  [{:a => :b}]
+  [['a', 'b']]
+</code></pre>
+
+Like its smaller brother, <code>sequence</code> is very picky about what it
+consumes and what not. All for the same reasons. 
+
+h3. Matching entire subtrees
+
+So you don't want to listen and really want that big gun with the foot aiming
+addon. You'll be needing <code>subtree(symbol)</code>. It always matches. 
+Nuff said. 
+
+h3. Matching context
+
+A match always binds in a context. The context consists of all bindings
+that were previously made. If you reuse the same symbol for two consecutive
+matches within the same pattern, the engine will assume that you want these
+two matched objects to be equal (under <code>==</code>). This allows to 
+specify constraints on your matches that would need code to express otherwise: 
+
+<pre class="sh_ruby"><code>
+  # The following code is an excerpt from example/simple_xml.rb in the distro
+  t.rule(
+    open: {name: simple(:tag)}, 
+    close: {name: simple(:tag)}, 
+    inner: simple(:t)
+  ) { 'verified' }
+</code></pre>
+
+This replaces _matching_ open and close tags with the word 'verified',
+consuming them from the tree and allowing the same rule to match higher up. A
+valid XML tree will leave only the word 'verified' behind, while the parser
+will stop at the problem nodes in invalid trees.
+
+h2. Transformation rules
+
+In this chapter, we'll look more closely at transformation rules and the
+different ways they can be laid out in your code.
+
+h3. Usage Patterns
+
+The way the transformation engine is constructed, there is not one, but three
+ways to use it. Since at least one of those is inconvenient for you, the user,
+I am going to show only the remaining two, Variant 1 that produces an instance
+of the transform for direct use:
+
+<pre class="sh_ruby"><code>
+  # Variant 1
+  transform = Parslet::Transform.new do
+    rule(...) { ... } 
+    rule(...) { ... } 
+    rule(...) { ... } 
+  end
+  transform.apply(tree)
+</code></pre>
+
+and Variant 2 that allows constructing the transformation as a class: 
+
+<pre class="sh_ruby"><code>
+  # Variant 2
+  class MyTransform < Parslet::Transform
+    rule(...) { ... } 
+    rule(...) { ... } 
+    rule(...) { ... } 
+  end
+  MyTransform.new.apply(tree)
+</code></pre>
+
+I guess both have their sweet spot. 
+
+h3. Action blocks: Two flavors 
+
+As you might have noticed by now, parslet provides choice as well as nice
+parsers. To recap: Rules have a left side called _pattern_ and a right side 
+called _action block_:
+
+<pre class="sh_ruby"><code>
+  rule(PATTERN) {ACTION_BLOCK}
+</code></pre>
+
+There are two ways of writing action blocks, and the difference might be 
+fundamental to know to you one day. If written like this: 
+
+<pre class="sh_ruby"><code>
+  rule(:foo => simple(:x)) { puts x }
+</code></pre>
+
+the block will be able to access <code>x</code> as a local variable. This is 
+very convenient and shortens the action code, often to the point of being
+very expressive.
+
+But there is a _big downside_ to this way of writing things: The action block
+must be executed in the context of some magic instance that has <code>x</code>
+as a local method (aka accessor). You can only have one self at any one time; 
+variable access to the binding of the block isn't possible inside this kind
+of action blocks: 
+
+<pre class="sh_ruby"><code>
+  y = 12
+  rule(:foo => simple(:x)) { Integer(x) + y }
+</code></pre>
+
+This will (depending on the context) throw a <code>NameError</code> or a
+<code>NoMethodError</code>.
+
+But this can be fixed by using the other, less elegant style for action
+blocks:
+
+<pre class="sh_ruby"><code>
+  y = 12
+  rule(:foo => simple(:x)) { |dictionary| Integer(dictionary[:x]) + y }
+</code></pre>
+
+In this second flavor, the block gets executed in the context of definition, 
+whatever that was. This means that it can capture and access local variables
+just fine. Access to the bindings (called <code>dictionary</code> here) is 
+more clumsy, but hey, you can't have your cake and eat it too, I guess. Even 
+though that is a pity. 
+
+h2. A word on patterns
+
+Given the PORO hash
+
+<pre class="sh_ruby"><code>
+  { 
+    :dog => 'terrier', 
+    :cat => 'suit' }
+</code></pre>
+
+one might assume that the following rule matches <code>:dog</code> and
+replaces it by <code>'foo'</code>:
+
+<pre class="sh_ruby"><code>
+  rule(:dog => 'terrier') { 'foo' }
+</code></pre>
+
+This is frankly impossible. How would <code>'foo'</code> live besides
+<code>:cat => 'suit'</code> inside the hash? It cannot. This is why hashes are
+either matched completely, cats n' all, or not at all. 
+
+Transformations are there for one thing: Getting out of the hash/array/slice
+mess parslet creates (on purpose) into the realm of your own beautifully
+crafted AST classes. Such
+"AST":http://en.wikipedia.org/wiki/Abstract_syntax_tree nodes will generally
+correspond 1:1 to hashes inside your intermediary tree. 
+
+If transformations get you into a mess, remember this simple truth: They have
+been designed for the above purpose. Abusing them is fun (and almost all the
+examples in the project do so) but the mess you get when you do is all yours.
+
+If you are really desperate, try to look at the example in "Get Started":get-started.html or at the parser in the sample project
+"wt":https://github.com/kschiess/wt. Imitating them would be a good first step. And if all else fails, we're there for you, see the 'Contact' section in "Contribute":contribute.html.
+
+h2. Summary
+
+This concludes this (three part) introduction to parslet and leaves you with a
+good knowledge of most tricky parts. If you are missing some detail, maybe
+you can find it in the texts referenced "here":documentation.html? There is 
+also an entire page on the tricks useful in practice here: "Tricks":tricks.html.
+
+If not, please tell us about it. We'll include it in this documentation in no 
+time.

+title: Tricks for common situations
+---
+
+h2. Matching EOF (End Of File)
+
+Ahh Sir, you'll be needin what us parsers call _epsilon_: 
+
+<pre class="sh_ruby"><code>
+  rule(:eof) { any.absent? }
+</code></pre>
+
+Of course, most of us don't use this at all, since any parser has EOF as
+implicit last input.
+
+h2. Matching Strings Case Insensitive
+
+Parslet is fully hackable: You can use code to create parsers easily. Here's
+how I would match a string in case insensitive manner: 
+
+<pre class="sh_ruby"><code title="case insensitive match">
+  def stri(str)
+    key_chars = str.split(//)
+    key_chars.
+      collect! { |char| match["#{char.upcase}#{char.downcase}"] }.
+      reduce(:>>)
+  end
+
+  # Constructs a parser using a Parser Expression Grammar 
+  stri('keyword').parse "kEyWoRd"     # => "kEyWoRd"@0
+</code></pre>
+
+h2. Testing
+
+Parslet helps you to create parsers that are in turn created out of many small
+parsers. It is really turtles all the way down. Imagine you have a complex 
+parser: 
+
+<pre class="sh_ruby"><code>
+  class ComplexParser < Parslet::Parser
+    root :lots_of_stuff
+  
+    rule(:lots_of_stuff) { ... }
+  
+    # and many lines later: 
+    rule(:simple_rule) { str('a') }
+  end
+</code></pre>
+
+Also imagine that the parser (as a whole) fails to consume the 'a' that 
+<code>simple_rule</code> is talking about. 
+
+This kind of problem can very often be fixed by bisecting it into two possible
+problems. Either: 
+
+# the <code>lots_of_stuff</code> rule somehow doesn't place <code>simple_rule</code>
+  in the right context or
+# the <code>simple_rule</code> simply (hah!) fails to match its input. 
+
+I find it very useful in this situation to eliminate 2. from our options: 
+
+<pre class="sh_ruby"><code title="rspec">
+  require 'rspec'
+  require 'parslet/rig/rspec'
+  
+  class ComplexParser < Parslet::Parser
+    rule(:simple_rule) { str('a') }
+  end
+
+  describe ComplexParser  do
+    let(:parser) { ComplexParser.new }
+    context "simple_rule" do
+      it "should consume 'a'" do
+        parser.simple_rule.should parse('a')
+      end 
+    end
+  end
+  
+  RSpec::Core::Runner.run([])
+</code></pre>
+
+Output is: 
+<pre class="output">
+
+Example::ComplexParser
+  simple_rule
+    should consume 'a'
+
+Finished in 0.00115 seconds
+1 example, 0 failures
+</pre>
+
+Parslet parsers have one method per rule. These methods return valid parsers
+for a subset of your grammar. 
+
+h2. Error reports
+
+If your grammar fails and you're aching to know why, here's a bit of exception
+handling code that will help you out: 
+
+<pre class="sh_ruby"><code title="exception handling">
+  parser = str('foo')
+  begin
+    parser.parse('bar')
+  rescue Parslet::ParseFailed => error
+    puts error.cause.ascii_tree
+  end
+</code></pre>
+
+This should print something akin to: 
+
+<pre class="output"> 
+Expected "foo", but got "bar" at line 1 char 1.
+</pre>
+
+These error reports are probably the fastest way to know exactly where you
+went wrong (or where your input is wrong, which is aequivalent).
+
+And since this is such a common idiom, we provide you with a shortcut: to
+get the above, just: 
+
+<pre class="sh_ruby"><code>
+require 'parslet/convenience'
+parser.parse_with_debug(input)
+</code></pre>
+
+
+h3. Reporter engines
+
+Note that there is currently not one, but two error reporting engines! The 
+default engine will report errors in a structure that looks exactly like the
+grammar structure: 
+
+<pre class="sh_ruby"><code title="error reporter 1">
+  class P < Parslet::Parser
+    root(:body)
+    rule(:body) { elements }
+    rule(:elements) { (call | element).repeat(2) }
+    rule(:element) { str('bar') }
+    rule(:call) { str('baz') >> str('()') }
+  end
+  
+  begin
+    P.new.parse('barbaz')
+  rescue Parslet::ParseFailed => error
+    puts error.cause.ascii_tree
+  end
+</code></pre>
+
+Outputs: 
+
+<pre class="output"> 
+Expected at least 2 of CALL / ELEMENT at line 1 char 1.
+`- Expected one of [CALL, ELEMENT] at line 1 char 4.
+   |- Failed to match sequence ('baz' '()') at line 1 char 7.
+   |  `- Premature end of input at line 1 char 7.
+   `- Expected "bar", but got "baz" at line 1 char 4.
+</pre>
+
+Let's switch out the 'grammar structure' engine (called '<code>Tree</code>')
+with the 'deepest error position' engine:
+
+<pre class="sh_ruby"><code title="error reporter 2">
+  class P < Parslet::Parser
+    root(:body)
+    rule(:body) { elements }
+    rule(:elements) { (call | element).repeat(2) }
+    rule(:element) { str('bar') }
+    rule(:call) { str('baz') >> str('()') }
+  end
+  
+  begin
+    P.new.parse('barbaz', reporter: Parslet::ErrorReporter::Deepest.new)
+  rescue Parslet::ParseFailed => error
+    puts error.cause.ascii_tree
+  end
+</code></pre>
+
+Outputs: 
+
+<pre class="output"> 
+Expected at least 2 of CALL / ELEMENT at line 1 char 1.
+`- Expected one of [CALL, ELEMENT] at line 1 char 4.
+   |- Failed to match sequence ('baz' '()') at line 1 char 7.
+   |  `- Premature end of input at line 1 char 7.
+   `- Premature end of input at line 1 char 7.
+</pre>
+
+The <code>'Deepest'</code> position engine will store errors that are the
+farthest into the input. In some examples, this produces more readable output
+for the end user. 
+
+h2. Line numbers from parser output
+
+A traditional parser would parse and then perform several checking phases,
+like for example verifying all type constraints are respected in the input.
+During this checking phase, you will most likely want to report screens full
+of type errors back to the user ('cause that's what types are for, right?).
+Now where did that 'int' come from?
+
+Parslet gives you slices (Parslet::Slice) of input as part of your tree. These
+are essentially strings with line numbers. Here's how to print that error
+message:
+
+<pre class="sh_ruby"><code>
+  # assume that type == "int"@0 - a piece from your parser output
+  line, col = type.line_and_column
+  puts "Sorry. Can't have #{type} at #{line}:#{col}!"
+</code></pre>

+
+## version 0.5.3: 2013-09-15

+
+  * Fix non-default themes (thanks @tiroc!)
+  * Minor lexing bugfixes in ruby
+
+## version 0.5.0: 2013-09-02

+  * golang: performance bump
+  * ruby: fix edge case for `def-@`
+  * c: fix a pathological performance case
+  * fix line number alignment on non-newline-terminated code (#91)
+
+### Breaking API Changes in v0.5.0
+
+  * `Rouge::Lexers::Text` renamed to `Rouge::Lexers::PlainText`
+  * Tokens are now constants, rather than strings.  This only affects
+    you if you've written a custom lexer, formatter, or theme.
+
+[perf-0.5]: https://github.com/jayferd/rouge/pull/41#issuecomment-23561787
+
+## version 0.4.0: 2013-08-14
+
+  * Add the `:inline_theme` option to `Formatters::HTML` for environments
+    that don't support stylesheets (like super-old email clients)
+  * Improve documentation of `Formatters::HTML` options
+  * bugfix: don't include subsequent whitespace in an elixir keyword.
+    In certain fonts/themes, this can cause inconsistent indentation if
+    bold spaces are wider than non-bold spaces.  (thanks @splattael!)
+
+## version 0.3.10: 2013-07-31
+
+  * Add the `license` key in the gemspec
+  * new lexer: R

+
+  * new lexers:
+    - elixir (thanks @splattael!)
+    - racket (thanks @greghendershott!)
+
+## version 0.3.8: 2013-07-02
+
+  * new lexers:
+    - erlang! (thanks @potomak!)
+    - http (with content-type based delegation)
+  * bugfix: highlight true and false in JSON
+
+## version 0.3.7: 2013-06-07
+
+  * bugfix: Add the local lib dir to the path in ./bin/rougify
+    so the internal `require` works properly.
+  * php: Properly lex variables in double-quoted strings and provide the
+    correct token for heredocs (thanks @hrysd!)
+  * Add a `:wrap` option to the html formatter (default true) to provide
+    the `<pre>` wrapper.  This allows skipping the wrapper entirely for
+    postprocessing.  (thanks @cjohansen!)
+
+## version 0.3.6: 2013-05-27
+
+  * fixed bad release that included unfinished D and wdiff lexers :\
+
+## version 0.3.5: 2013-05-24
+
+  * Added a github theme (thanks @simonc!) (#75)
+  * Correctly highlight ruby 1.9-style symbols and %i() syntax
+    (thanks @simonc!) (#74)
+  * Fixed a performance bug in the C++ lexer (#73)
+    reported by @jeffgran
+
+## version 0.3.4: 2013-05-02

+## version 0.3.1: 2013-03-11
+
+  * Hotfix release: fix errors loading the SCSS lexer on some systems.
+
+## version 0.3.0: 2013-03-06
+
+  * Refactor source guessing to return fewer false positives, and
+    to be better at disambiguating between filename matches (such as
+    `nginx.conf` vs. `*.conf`, or `*.pl` for both prolog and perl)
+  * Added `Lexer.guesses` which can return multiple or zero results for a
+    guess.
+  * Fix number literals in C#
+  * New lexers:
+    - Gherkin (cucumber)
+    - Prolog (@coffeejunk)
+    - LLVM (@coffeejunk)
+
+## version 0.2.15: 2013-03-03
+
+  * New lexer: lua (thanks, @nathany!)
+  * Add extra filetypes that map to Ruby (`Capfile`, `Vagrantfile`,
+    `*.ru` and `*.prawn`) (@nathany)
+  * Bugfix: add demos for ini and toml
+  * The `thankful_eyes` theme now colors `Literal.Date`
+  * No more gigantic load list in `lib/rouge.rb`

+  * Stop trying to read /etc/bash.bashrc in the specs (@coffeejunk)
+
+## version 0.2.13: 2013-02-12
+
+  * Highlight ClojureScipt files (`*.cljs`) as Clojure (@blom)
+  * README and doc enhancements (plus an actual wiki!) (@robin850)
+  * Don't open `Regexp`, especially if we're not adding anything to it.
+
+## version 0.2.12: 2013-02-07
+
+  * Python: bugfix for lone quotes in triple-quoted strings

+  * (@korny) Future-proofed the regexes in the Perl lexer
+  * `rougify` now streams the formatted text to stdout as it's
+    available instead of waiting for the lex to be done.
+
+## version 0.2.8: 2012-10-30
+
+  * Bugfix for tableized line numbers when the code doesn't end
+    with a newline.
+
+## version 0.2.7: 2012-10-22
+
+  * Major performance improvements.  80% running time reduction for
+    some files since v0.2.5 (thanks again @korny!)
+  * Deprecated `postprocess` for performance reasons - it wasn't that
+    useful in the first place.
+  * The shell lexer should now recognize .bashrc, .profile and friends
+
+## version 0.2.6: 2012-10-21
+  * coffeescript: don't yield error tokens for keywords as attributes
+  * add the `--scope=SELECTOR` option to `rougify style`
+  * Add the `:line_numbers` option to the HTML formatter to get line
+    numbers!  The styling for the line numbers is determined by
+    the theme's styling for `'Generic.Lineno'`
+  * Massive performance improvements by reducing calls to `option`
+    and to `Regexp#source` (@korny)
+
+## version 0.2.5: 2012-10-20
+  * hotfix: ship the demos with the gem.
+
+## version 0.2.4: 2012-10-20
+
+  * Several improvements to the javasript and scheme lexers
+  * Lexer.demo, with small demos for each lexer
+  * Rouge.highlight takes a string for the formatter
+  * Formatter.format delegates to the instance
+  * sass: Support the @extend syntax, fix new-style attributes, and
+    support 3.2 placeholder syntax
+
+## version 0.2.3: 2012-10-16
+
+  * Fixed several postprocessing-related bugs
+  * New lexers: coffeescript, sass, smalltalk, handlebars/mustache
+
+## version 0.2.2: 2012-10-13
+
+  * In terminal256, stop highlighting backgrounds of text-like tokens
+  * Fix a bug which was breaking guessing with filenames beginning with .
+  * Fix the require path for redcarpet in the README (@JustinCampbell)
+  * New lexers: clojure, groovy, sass, scss
+  * YAML: detect files with the %YAML directive
+  * Fail fast for non-UTF-8 strings
+  * Formatter#render deprecated, renamed to Formatter#format.
+    To be removed in v0.3.
+  * Lexer#tag delegates to the class
+  * Better keyword/builtin highlighting for CSS
+  * Add the `:token` option to the text lexer
+
+## version 0.2.1: 2012-10-11
+
+  * Began the changelog
+  * Removed several unused methods and features from Lexer and RegexLexer
+  * Added a lexer for SQL
+  * Added a lexer for VimL, along with `rake builtins:vim`
+  * Added documentation for RegexLexer, TextAnalyzer, and the formatters
+  * Refactored `rake phpbuiltins` - renamed to `rake builtins:php`
+  * Fixed a major bug in the Ruby lexer that prevented highlighting the
+    `module` keyword.
+  * Changed the default formatter for the `rougify` executable to
+    `terminal256`.
+  * Implemented `rougify list`, and added short descriptions to all of
+    the lexers.
+  * Fixed a bug in the C lexer that was yielding error tokens in case
+    statements.

+# Rouge
+
+[![Build Status](https://secure.travis-ci.org/jneen/rouge.png)](http://travis-ci.org/jneen/rouge)
+[![Gem Version](https://badge.fury.io/rb/rouge.png)](http://badge.fury.io/rb/rouge)
+
+Rouge is a pure-ruby syntax highlighter.  It can highlight over 60 languages, and output HTML or ANSI 256-color text.  Its HTML output is compatible with stylesheets designed for [pygments][].
+
+If you'd like to help out with this project, assign yourself something from the [issues][] page, and send me a pull request (even if it's not done yet!).  Bonus points for feature branches.  In particular, I would appreciate help with the following lexers, from someone who has more experience with the language than I do:
+
+* Delphi/Pascal
+
+Also, if anyone with design skills feels like helping me make a website for rouge, I'd really appreciate the help.  So far all I've got is the [demo page][pretty colors].
+
+[issues]: https://github.com/jayferd/rouge/issues "Help Out"
+[pygments]: http://pygments.org/ "Pygments"
+
+## Usage
+
+First, take a look at the [pretty colors][].
+
+[pretty colors]: http://rouge.jayferd.us/demo
+
+``` ruby
+# make some nice lexed html
+source = File.read('/etc/bashrc')
+formatter = Rouge::Formatters::HTML.new(css_class: 'highlight')
+lexer = Rouge::Lexers::Shell.new
+formatter.format(lexer.lex(source))
+
+# Get some CSS
+Rouge::Themes::Base16.mode(:light).render(scope: '.highlight')
+# Or use Theme#find with string input
+Rouge::Theme.find('base16.light').render(scope: '.highlight')
+```
+
+####Full options:
+
+Formatter options:
+
+      css_class: 'highlight'  #  Apply a class to the syntax-highlighted output.
+                              #  Set to false to not apply any css class
+      line_numbers: false     #  Generate line numbers.
+      start_line: 1           #  Index to start line numbers.
+      inline_theme: nil       #  A Rouge::CSSTheme used to highlight the output with inline styles
+                              #  instead of classes. Allows string inputs (separate mode with a dot):
+                              #  %w[colorful github monokai monokai.sublime thankful_eyes base16
+                              #     base16.dark base16.light base16.solarized base16.monokai]
+      wrap: true              #  Wrap the highlighted content in a container.
+                              #  Defaults to <pre><code>, or <div> if line numbers are enabled.
+
+Lexer options:
+
+      debug: false            #  Print a trace of the lex on stdout
+      parent: ''              #  Allows you to specify which language the template is inside
+
+CSS theme options:
+
+      scope: '.highlight'     #  CSS selector that styles are applied to
+                              #  E.g. Rouge::Themes::Monokai.mode(:sublime).render(scope: 'code')
+
+Rouge aims to be simple to extend, and to be a drop-in replacement for pygments, with the same quality of output.
+
+Also, Rouge ships with a `rougify` command which allows you to easily highlight files in your terminal:
+
+``` bash
+$ rougify foo.rb
+$ rougify style monokai.sublime > syntax.css
+```
+
+### Advantages to pygments.rb
+* No need to [spawn Python processes](https://github.com/tmm1/pygments.rb).
+
+### Advantages to CodeRay
+* The HTML output from Rouge is fully compatible with stylesheets designed for pygments.
+* The lexers are implemented with a dedicated DSL, rather than being hand-coded.
+* Rouge supports every language CodeRay does except for Pascal/Delphi (pull requests happily accepted!), and more.
+
+## You can even use it with Redcarpet
+
+``` ruby
+require 'redcarpet'
+require 'rouge'
+require 'rouge/plugins/redcarpet'
+
+class HTML < Redcarpet::Render::HTML
+  include Rouge::Plugins::Redcarpet # yep, that's it.
+end
+```
+
+If you have `:fenced_code_blocks` enabled, you can specify languages, and even options with CGI syntax, like `php?start_inline=1`, or `erb?parent=javascript`.
+
+## Encodings
+
+Rouge is only for UTF-8 strings.  If you'd like to highlight a string with a different encoding, please convert it to UTF-8 first.
+
+## Other integrations
+
+* Middleman: [middleman-syntax](https://github.com/middleman/middleman-syntax) (@bhollis)
+* Middleman: [middleman-rouge][] (@Linuus)
+* RDoc: [rdoc-rouge][] (@zzak)

+
+## Contributing
+
+### Installing Ruby
+
+If you're here to implement a lexer for your awesome language, there's a good chance you don't already have a ruby development environment set up.  Follow the [instructions on the wiki](https://github.com/jayferd/rouge/wiki/Setting-up-Ruby) to get up and running.  If you have trouble getting set up, let me know - I'm always happy to help.
+
+### Run the tests
+
+You can test the core of Rouge simply by running `rake` (no `bundle exec` required).  It's also set up with `guard`, if you like.
+
+To test a lexer visually, run `rackup` from the root and go to `localhost:9292/#{some_lexer}` where `some_lexer` is the tag or an alias of a lexer you'd like to test.  If you add `?debug=1`, helpful debugging info will be printed on stdout.
+
+### API Documentation
+
+is at http://rubydoc.info/gems/rouge/frames.
+
+### Using the lexer DSL
+
+You can probably learn a lot just by reading through the existing lexers.  Basically, a lexer consists of a collection of states, each of which has several rules.  A rule consists of a regular expression and an action, which yields tokens and manipulates the state stack.  Each rule in the state on top of the stack is tried *in order* until a match is found, at which point the action is run, the match consumed from the stream, and the process repeated with the new lexer on the top of the stack.  Each lexer has a special state called `:root`, and the initial state stack consists of just this state.
+
+Here's how you might use it:
+
+``` ruby
+class MyLexer < Rouge::RegexLexer
+  state :root do
+    # the "easy way"
+
+    # simple rules
+    rule /0x[0-9a-f]+/, Num::Hex
+
+    # simple state stack manipulation
+    rule /{-/, Comment, :next_state
+    rule /-}/, Comment, :pop!
+
+    # the "flexible way"
+    rule /abc/ do |m|
+      # m is the match, for accessing match groups manually
+
+      # you can do the following things:
+      pop!
+      push :another_state
+      push # assumed to be the current state
+      state? :some_state # check if the current state is :some_state
+      in_state? :some_state # check if :some_state is in the state stack
+
+      # yield a token.  if no second argument is supplied, the value is
+      # taken to be the whole match.
+      # The sum of all the tokens yielded must be equivalent to the whole
+      # match - otherwise characters will go missing from the user's input.
+      token Generic::Output, m[0]
+
+      # calls SomeOtherLexer.lex(str) and yields its output.  See the
+      # HTML lexer for a nice example of this.
+      # if no second argument is supplied, it is assumed to be the whole
+      # match string.
+      delegate SomeOtherLexer, str
+
+      # the context object is the lexer itself, so you can stash state here
+      @count ||= 0
+      @count += 1
+
+      # advanced: push a dynamically created anonymous state
+      push do
+        rule /.../, Generic::Output
+      end
+    end
+
+    rule /(\w+)(:)/
+      # "groups" yields the matched groups in order
+      groups Name::Label, Punctuation
+    end
+  end
+
+  start do
+    # this is run whenever a fresh lex is started
+  end
+end
+```

+(defn gen-class 
+  "Generates compiled bytecode for a class with the given
+  package-qualified cname (which, as all names in these parameters, can
+  be a string or symbol). The gen-class construct contains no
+  implementation, as the implementation will be dynamically sought by
+  the generated class in functions in a corresponding Clojure
+  namespace. Given a generated class org.mydomain.MyClass, methods
+  will be implemented that look for same-named functions in a Clojure
+  namespace called org.domain.MyClass. The init and main
+  functions (see below) will be found similarly. The static
+  initializer for the generated class will attempt to load the Clojure
+  support code for the class as a resource from the claspath, e.g. in
+  the example case, org/mydomain/MyClass.clj
+
+  Returns a map containing :name and :bytecode. Most uses will be
+  satisfied by the higher-level gen-and-load-class and
+  gen-and-store-class functions, which generate and immediately load,
+  or generate and store to disk, respectively.
+
+  Options should be a set of key/value pairs, all of which are optional:
+
+  :extends aclass
+
+  Specifies the superclass, the non-private methods of which will be
+  overridden by the class. If not provided, defaults to Object.
+
+  :implements [interface ...]
+
+  One or more interfaces, the methods of which will be implemented by the class.
+
+  :init name
+
+  If supplied, names a function that will be called with the arguments
+  to the constructor. Must return [[superclass-constructor-args] state] 
+  If not supplied, the constructor args are passed directly to
+  the superclass constructor and the state will be nil
+
+  :constructors {[param-types] [super-param-types], ...}
+
+  By default, constructors are created for the generated class which
+  match the signature(s) of the constructors for the superclass. This
+  parameter may be used to explicitly specify constructors, each entry
+  providing a mapping from a constructor signature to a superclass
+  constructor signature. When you supply this, you must supply an :init
+  specifier.
+
+  :methods [[name [param-types] return-type], ...]
+
+  The generated class automatically defines all of the non-private
+  methods of its superclasses/interfaces. This parameter can be used
+  to specify the signatures of additional methods of the generated
+  class. Do not repeat superclass/interface signatures here.
+
+  :main boolean
+
+  If supplied and true, a static public main function will be
+  generated. It will pass each string of the String[] argument as a
+  separate argument to a function called 'main.
+
+  :factory name
+
+  If supplied, a (set of) public static factory function(s) will be
+  created with the given name, and the same signature(s) as the
+  constructor(s).
+  
+  :state name
+
+  If supplied, a public final instance field with the given name will be
+  created. You must supply an :init function in order to provide a
+  value for the state. Note that, though final, the state can be a ref
+  or agent, supporting the creation of Java objects with transactional
+  or asynchronous mutation semantics.
+
+  :exposes {protected-field-name {:get name :set name}, ...}
+
+  Since the implementations of the methods of the generated class
+  occur in Clojure functions, they have no access to the inherited
+  protected fields of the superclass. This parameter can be used to
+  generate public getter/setter methods exposing the protected field(s)
+  for use in the implementation."

+# ---------------
+
+# The Lexer class reads a stream of CoffeeScript and divvies it up into tagged
+# tokens. Some potential ambiguity in the grammar has been avoided by
+# pushing some extra smarts into the Lexer.
+exports.Lexer = class Lexer
+
+  # **tokenize** is the Lexer's main method. Scan by attempting to match tokens
+  # one at a time, using a regular expression anchored at the start of the
+  # remaining code, or a custom recursive token-matching method
+  # (for interpolations). When the next token has been recorded, we move forward
+  # within the code past the token, and begin again.
+  #
+  # Each tokenizing method is responsible for returning the number of characters
+  # it has consumed.
+  #
+  # Before returning the token stream, run it through the [Rewriter](rewriter.html)
+  # unless explicitly asked not to.

+;;; Datenstrukturen für TYPEP:
+;;; - Ein Type-Specifier-Symbol hat auf seiner Propertyliste unter dem
+;;;   Indikator SYS::TYPE-SYMBOL eine Funktion von einem Argument, die
+;;;   testet, ob ein Objekt vom richtigen Typ ist.
+;;; - Ein Symbol, das eine Type-Specifier-Liste beginnen kann, hat auf seiner
+;;;   Propertyliste unter dem Indikator SYS::TYPE-LIST eine Funktion von
+;;;   einem Argument für das zu testende Objekt und zusätzlichen Argumenten
+;;;   für die Listenelemente.
+;;; - Ein Symbol, das als Typmacro definiert wurde, hat auf seiner Property-
+;;;   liste unter dem Indikator SYSTEM::DEFTYPE-EXPANDER den zugehörigen
+;;;   Expander: eine Funktion, die den zu expandierenden Type-Specifier (eine
+;;;   mindestens einelementige Liste) als Argument bekommt.

+ # Rouge
+ 
+-This project is not yet finished, but this works:
++This project needs your help!  There are lots of lexers to be implemented / ported / fixed, and features that need to be added or implemented.  If you'd like to help out, send me a pull request (even if it's not done yet!).  Bonus points for feature branches.
++
++## Usage
+ 
+ ``` ruby
+-formatter = Rouge::Formatters::HTML.new
++# make some nice lexed html, compatible with pygments stylesheets
++formatter = Rouge::Formatters::HTML.new(:css_class => '.highlight')
+ Rouge.highlight(File.read('/etc/bash.bashrc'), 'shell', formatter)
++
++# apply a theme
++Rouge::Themes::ThankfulEyes.new(:scope => '.highlight').render
+ ```
+ 
+-More features, documentation, lexers, and formatters to come.  Help is appreciated, too, if you think this is awesome :)
++Rouge aims to be simple to extend, and to be a drop-in replacement pygments, with the same quality of output.
++
++### Advantages to pygments.rb
++* No python bridge is necessary - you can deploy it on Heroku effortlessly, without the need for [epic hacks][].

+
+      defmodule App do
+        use ModuleTest::ToBeUsed

+
+  In the example above, `MyLib` defines a data to the target. This data

+  which will read the final value of :some_data and compile to a function.

+% Percent sign start a one-line comment.
+
+%% Two percent characters shall be used to comment functions.
+
+%%% Three percent characters shall be used to comment modules.
+
+% We use three types of punctuation in Erlang.
+% Commas (`,`) separate arguments in function calls, data constructors, and
+% patterns.
+% Periods (`.`) (followed by whitespace) separate entire functions and
+% expressions in the shell.
+% Semicolons (`;`) separate clauses. We find clauses in several contexts: in kn
+% function definitions and in `case`, `if`, `try..catch` and `receive`
+% expressions.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%% 1. Variables and pattern matching.
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+Num = 42.  % All variable names must start with an uppercase letter.
+% Erlang has single assignment variables, if you try to assign a different value
+% to the variable `Num`, you’ll get an error.
+
+% In most languages, `=` denotes an assignment statement. In Erlang, however,
+% `=` denotes a pattern matching operation. `Lhs = Rhs` really means this:
+% evaluate the right side (Rhs), and then match the result against the pattern
+% on the left side (Lhs).
+Num = 7 * 6.
+
+% Floating point number.
+Pi = 3.14159.
+
+% Atoms, are used to represent different non-numerical constant values. Atoms
+% start with lowercase letters, followed by a sequence of alphanumeric
+% characters or the underscore (`_`) or at (`@`) sign.
+Hello = hello.
+
+% Tuples are similar to structs in C.
+Point = {point, 10, 45}.
+
+% If we want to extract some values from a tuple, we use the pattern matching
+% operator `=`.
+{point, X, Y} = Point.  % X = 10, Y = 45
+
+% We can use `_` as a placeholder for variables that we’re not interested in.
+% The symbol `_` is called an anonymous variable. Unlike regular variables,
+% several occurrences of _ in the same pattern don’t have to bind to the same
+% value.
+Person = {person, {name, {first, joe}, {last, armstrong}}, {footsize, 42}}.
+{_, {_, {_, Who}, _}, _} = Person.  % Who = joe
+
+% We create a list by enclosing the list elements in square brackets and
+% separating them with commas.
+% The individual elements of a list can be of any type.
+% The first element of a list the head of the list. If you imagine removing the
+% head from the list, what’s left is called the tail of the list.
+ThingsToBuy = [{apples, 10}, {pears, 6}, {milk, 3}].
+
+% If `T` is a list, then `[H|T]` is also a list, with head H and tail T.
+% The vertical bar (`|`) separates the head of a list from its tail.
+% `[]` is the empty list.
+% We can extract elements from a list with a pattern matching operation. If we
+% have the nonempty list `L`, then the expression `[X|Y] = L`, where `X` and `Y`
+% are unbound variables, will extract the head of the list into `X` and the tail
+% of the list into `Y`.
+[FirstThing|OtherThingsToBuy] = ThingsToBuy.
+% FirstThing = {apples, 10}
+% OtherThingsToBuy = {pears, 6}, {milk, 3}
+
+% There are no strings in Erlang. Strings are really just lists of integers.
+% Strings are enclosed in double quotation marks (`"`).
+Name = "Hello".

+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%% 2. Sequential programming.
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+% Modules are the basic unit of code in Erlang. All the functions we write are
+% stored in modules. Modules are stored in files with `.erl` extensions.
+% Modules must be compiled before the code can be run. A compiled module has the
+% extension `.beam`.
+-module(geometry).
+-export([area/1]).
+
+% The function area consists of two clauses. The clauses are separated by a
+% semicolon, and the final clause is terminated by dot-whitespace.
+% Each clause has a head and a body; the head consists of a function name
+% followed by a pattern (in parentheses), and the body consists of a sequence of
+% expressions, which are evaluated if the pattern in the head is successfully
+% matched against the calling arguments. The patterns are matched in the order
+% they appear in the function definition.
+area({rectangle, Width, Ht}) -> Width * Ht;
+area({circle, R})            -> 3.14159 * R * R.
+
+% Compile the code in the file geometry.erl.
+c(geometry).  % {ok,geometry}
+
+% We need to include the module name together with the function name in order to
+% identify exactly which function we want to call.
+geometry:area({rectangle, 10, 5}).  % 50
+geometry:area({circle, 1.4}).  % 6.15752
+
+% In Erlang, two functions with the same name and different arity in the same
+% module represent entirely different functions.
+-module(lib_misc).
+-export([sum/1]).
+sum(L) -> sum(L, 0).
+sum([], N)    -> N;
+sum([H|T], N) -> sum(T, H+N).
+
+% Funs are "anonymous" functions. They are called this because they have no
+% name.
+Double = fun(X) -> 2*X end.
+Double(2).  % 4
+
+% Functions accept funs as their arguments and can return funs.
+Mult = fun(Times) -> ( fun(X) -> X * Times end ) end.
+Triple = Mult(3).
+Triple(5).  % 15
+
+% List comprehensions are expressions that create lists without having to use
+% funs, maps, or filters.
+% The notation `[F(X) || X <- L]` means "the list of `F(X)` where `X` is taken
+% from the list `L`."
+L = [1,2,3,4,5].
+[2*X || X <- L].  % [2,4,6,8,10]
+
+% Guards are constructs that we can use to increase the power of pattern
+% matching. Using guards, we can perform simple tests and comparisons on the
+% variables in a pattern.
+% You can use guards in the heads of function definitions where they are
+% introduced by the `when` keyword, or you can use them at any place in the
+% language where an expression is allowed.
+max(X, Y) when X > Y -> X;
+max(X, Y) -> Y.
+
+% A guard is a series of guard expressions, separated by commas (`,`).
+% The guard `GuardExpr1, GuardExpr2, ..., GuardExprN` is true if all the guard
+% expressions `GuardExpr1, GuardExpr2, ...` evaluate to true.
+is_cat(A) when is_atom(A), A =:= cat -> true;
+is_cat(A) -> false.
+is_dog(A) when is_atom(A), A =:= dog -> true;
+is_dog(A) -> false.
+
+% A `guard sequence` is either a single guard or a series of guards, separated
+%by semicolons (`;`). The guard sequence `G1; G2; ...; Gn` is true if at least
+% one of the guards `G1, G2, ...` evaluates to true.
+is_pet(A) when is_dog(A); is_cat(A) -> true;
+is_pet(A) -> false.
+
+% Records provide a method for associating a name with a particular element in a
+% tuple.
+% Record definitions can be included in Erlang source code files or put in files
+% with the extension `.hrl`, which are then included by Erlang source code
+% files.
+-record(todo, {
+  status = reminder,  % Default value
+  who = joe,
+  text
+}).
+
+% We have to read the record definitions into the shell before we can define a
+% record. We use the shell function `rr` (short for read records) to do this.
+rr("records.hrl").  % [todo]
+
+% Creating and updating records:
+X = #todo{}.
+% #todo{status = reminder, who = joe, text = undefined}
+X1 = #todo{status = urgent, text = "Fix errata in book"}.
+% #todo{status = urgent, who = joe, text = "Fix errata in book"}
+X2 = X1#todo{status = done}.
+% #todo{status = done,who = joe,text = "Fix errata in book"}
+
+% `case` expressions.
+% `filter` returns a list of all those elements `X` in `L` for which `P(X)` is
+% true.
+filter(P, [H|T]) ->
+  case P(H) of
+    true -> [H|filter(P, T)];
+    false -> filter(P, T)
+  end;
+filter(P, []) -> [].
+
+% `if` expressions.
+max(X, Y) ->
+  if
+    X > Y -> X;
+    X < Y -> Y;
+    true -> nil;
+  end.
+
+% Warning: at least one of the guards in the if expression must evaluate to true;
+% otherwise, an exception will be raised.
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%% 3. Exceptions.
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+% Exceptions are raised by the system when internal errors are encountered or
+% explicitly in code by calling `throw(Exception)`, `exit(Exception)` or
+% `erlang:error(Exception)`.
+generate_exception(1) -> a;
+generate_exception(2) -> throw(a);
+generate_exception(3) -> exit(a);
+generate_exception(4) -> {'EXIT', a};
+generate_exception(5) -> erlang:error(a).
+
+% Erlang has two methods of catching an exception. One is to enclose the call to
+% the function, which raised the exception within a `try...catch` expression.
+catcher(N) ->
+  try generate_exception(N) of
+    Val -> {N, normal, Val}
+  catch
+    throw:X -> {N, caught, thrown, X};
+    exit:X -> {N, caught, exited, X};
+    error:X -> {N, caught, error, X}
+  end.
+
+% The other is to enclose the call in a `catch` expression. When you catch an
+% exception, it is converted into a tuple that describes the error.
+catcher(N) -> catch generate_exception(N).

+The **Scope** class regulates lexical scoping within CoffeeScript. As you
+generate code, you create a tree of scopes in the same shape as the nested
+function bodies. Each scope knows about the variables declared within it,
+and has a reference to its parent enclosing scope. In this way, we know which
+variables are new and need to be declared with `var`, and which are shared
+with external scopes.
+
+Import the helpers we plan to use.
+
+    {extend, last} = require './helpers'
+
+    exports.Scope = class Scope
+
+The `root` is the top-level **Scope** object for a given file.
+
+      @root: null
+
+Initialize a scope with its parent, for lookups up the chain,
+as well as a reference to the **Block** node it belongs to, which is
+where it should declare its variables, and a reference to the function that
+it belongs to.
+
+      constructor: (@parent, @expressions, @method) ->
+        @variables = [{name: 'arguments', type: 'arguments'}]
+        @positions = {}
+        Scope.root = this unless @parent
+
+Adds a new variable or overrides an existing one.
+
+      add: (name, type, immediate) ->

+          @variables[@positions[name]].type = type
+        else
+          @positions[name] = @variables.push({name, type}) - 1
+
+When `super` is called, we need to find the name of the current method we're
+in, so that we know how to invoke the same method of the parent class. This
+can get complicated if super is being called from an inner function.
+`namedMethod` will walk up the scope tree until it either finds the first
+function object that has a name filled in, or bottoms out.
+
+      namedMethod: ->
+        return @method if @method.name or !@parent
+        @parent.namedMethod()

+already exist.
+
+      find: (name) ->
+        return yes if @check name
+        @add name, 'var'
+        no
+
+Reserve a variable name as originating from a function parameter for this
+scope. No `var` required for internal references.
+
+      parameter: (name) ->
+        return if @shared and @parent.check name, yes
+        @add name, 'param'
+
+Just check to see if a variable has already been declared, without reserving,
+walks up to the root scope.
+
+      check: (name) ->
+        !!(@type(name) or @parent?.check(name))
+
+Generate a temporary variable name at the given index.
+
+      temporary: (name, index) ->

+        else
+          '_' + (index + parseInt name, 36).toString(36).replace /\d/g, 'a'
+
+Gets the type of a variable.
+
+      type: (name) ->
+        return v.type for v in @variables when v.name is name
+        null
+
+If we need to store an intermediate result, find an available name for a
+compiler-generated variable. `_var`, `_var2`, and so on...
+
+      freeVariable: (name, reserve=true) ->
+        index = 0
+        index++ while @check((temp = @temporary name, index))
+        @add temp, 'var', yes if reserve
+        temp
+
+Ensure that an assignment is made at the top of this scope
+(or at the top-level scope, if requested).
+
+      assign: (name, value) ->
+        @add name, {value, assigned: yes}, yes

+
+Does this scope have any declared variables?
+
+      hasDeclarations: ->

+          (if v.name.charAt(0) is '_' then tempVars else realVars).push v.name

+<h2 id="overview">Overview</h2>
+
+<h3 id="philosophy">Philosophy</h3>
+
+Markdown is intended to be as easy-to-read and easy-to-write as is feasible.
+
+Readability, however, is emphasized above all else. A Markdown-formatted
+document should be publishable as-is, as plain text, without looking
+like it's been marked up with tags or formatting instructions. While
+Markdown's syntax has been influenced by several existing text-to-HTML
+filters -- including [Setext] [1], [atx] [2], [Textile] [3], [reStructuredText] [4],
+[Grutatext] [5], and [EtText] [6] -- the single biggest source of
+inspiration for Markdown's syntax is the format of plain text email.
+
+  [1]: http://docutils.sourceforge.net/mirror/setext.html
+  [2]: http://www.aaronsw.com/2002/atx/
+  [3]: http://textism.com/tools/textile/
+  [4]: http://docutils.sourceforge.net/rst.html
+  [5]: http://www.triptico.com/software/grutatxt.html
+  [6]: http://ettext.taint.org/doc/
+
+To this end, Markdown's syntax is comprised entirely of punctuation
+characters, which punctuation characters have been carefully chosen so
+as to look like what they mean. E.g., asterisks around a word actually
+look like \*emphasis\*. Markdown lists look like, well, lists. Even
+blockquotes look like quoted passages of text, assuming you've ever
+used email.
+
+
+
+<h3 id="html">Inline HTML</h3>
+
+Markdown's syntax is intended for one purpose: to be used as a
+format for *writing* for the web.
+
+Markdown is not a replacement for HTML, or even close to it. Its
+syntax is very small, corresponding only to a very small subset of
+HTML tags. The idea is *not* to create a syntax that makes it easier
+to insert HTML tags. In my opinion, HTML tags are already easy to
+insert. The idea for Markdown is to make it easy to read, write, and
+edit prose. HTML is a *publishing* format; Markdown is a *writing*
+format. Thus, Markdown's formatting syntax only addresses issues that
+can be conveyed in plain text.
+
+For any markup that is not covered by Markdown's syntax, you simply
+use HTML itself. There's no need to preface it or delimit it to
+indicate that you're switching from Markdown to HTML; you just use
+the tags.
+
+The only restrictions are that block-level HTML elements -- e.g. `<div>`,
+`<table>`, `<pre>`, `<p>`, etc. -- must be separated from surrounding
+content by blank lines, and the start and end tags of the block should
+not be indented with tabs or spaces. Markdown is smart enough not
+to add extra (unwanted) `<p>` tags around HTML block-level tags.
+
+For example, to add an HTML table to a Markdown article:
+
+    This is a regular paragraph.
+
+    <table>
+        <tr>
+            <td>Foo</td>
+        </tr>
+    </table>
+
+    This is another regular paragraph.
+
+highlighted:
+
+This is a regular paragraph.
+
+<table>
+    <tr>
+        <td>Foo</td>
+    </tr>
+</table>
+
+This is another regular paragraph.
+
+Note that Markdown formatting syntax is not processed within block-level
+HTML tags. E.g., you can't use Markdown-style `*emphasis*` inside an
+HTML block.
+
+Span-level HTML tags -- e.g. `<span>`, `<cite>`, or `<del>` -- can be
+used anywhere in a Markdown paragraph, list item, or header. If you
+want, you can even use HTML tags instead of Markdown formatting; e.g. if
+you'd prefer to use HTML `<a>` or `<img>` tags instead of Markdown's
+link or image syntax, go right ahead.
+
+Unlike block-level HTML tags, Markdown syntax *is* processed within
+span-level tags.
+
+
+<h3 id="autoescape">Automatic Escaping for Special Characters</h3>
+
+In HTML, there are two characters that demand special treatment: `<`
+and `&`. Left angle brackets are used to start tags; ampersands are
+used to denote HTML entities. If you want to use them as literal
+characters, you must escape them as entities, e.g. `<`, and
+`&`.
+
+Ampersands in particular are bedeviling for web writers. If you want to
+write about 'AT&T', you need to write '`AT&T`'. You even need to
+escape ampersands within URLs. Thus, if you want to link to:
+
+    http://images.google.com/images?num=30&q=larry+bird
+
+http://images.google.com/images?num=30&q=larry+bird
+
+you need to encode the URL as:
+
+    http://images.google.com/images?num=30&q=larry+bird
+
+in your anchor tag `href` attribute. Needless to say, this is easy to
+forget, and is probably the single most common source of HTML validation
+errors in otherwise well-marked-up web sites.
+
+Markdown allows you to use these characters naturally, taking care of
+all the necessary escaping for you. If you use an ampersand as part of
+an HTML entity, it remains unchanged; otherwise it will be translated
+into `&`.
+
+So, if you want to include a copyright symbol in your article, you can write:
+
+    ©
+
+©
+
+and Markdown will leave it alone. But if you write:
+
+    AT&T
+
+AT&T
+
+Markdown will translate it to:
+
+    AT&T
+
+Similarly, because Markdown supports [inline HTML](#html), if you use
+angle brackets as delimiters for HTML tags, Markdown will treat them as
+such. But if you write:
+
+    4 < 5
+
+highlighted:
+
+4 < 5
+
+Markdown will translate it to:
+
+    4 < 5
+
+However, inside Markdown code spans and blocks, angle brackets and
+ampersands are *always* encoded automatically. This makes it easy to use
+Markdown to write about HTML code. (As opposed to raw HTML, which is a
+terrible format for writing about HTML syntax, because every single `<`
+and `&` in your example code needs to be escaped.)
+
+
+* * *
+
+
+<h2 id="block">Block Elements</h2>
+
+
+<h3 id="p">Paragraphs and Line Breaks</h3>
+
+A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing but spaces or tabs is considered
+blank.) Normal paragraphs should not be indented with spaces or tabs.
+
+The implication of the "one or more consecutive lines of text" rule is
+that Markdown supports "hard-wrapped" text paragraphs. This differs
+significantly from most other text-to-HTML formatters (including Movable
+Type's "Convert Line Breaks" option) which translate every line break
+character in a paragraph into a `<br />` tag.
+
+When you *do* want to insert a `<br />` break tag using Markdown, you
+end a line with two or more spaces, then type return.
+
+Yes, this takes a tad more effort to create a `<br />`, but a simplistic
+"every line break is a `<br />`" rule wouldn't work for Markdown.
+Markdown's email-style [blockquoting][bq] and multi-paragraph [list items][l]
+work best -- and look better -- when you format them with hard breaks.
+
+  [bq]: #blockquote
+  [l]:  #list
+
+
+
+<h3 id="header">Headers</h3>
+
+Markdown supports two styles of headers, [Setext] [1] and [atx] [2].
+
+Setext-style headers are "underlined" using equal signs (for first-level
+headers) and dashes (for second-level headers). For example:
+
+    This is an H1
+    =============
+
+    This is an H2
+    -------------
+
+highlighted:
+
+This is an H1
+=============
+
+This is an H2
+-------------
+
+Any number of underlining `=`'s or `-`'s will work.
+
+Atx-style headers use 1-6 hash characters at the start of the line,
+corresponding to header levels 1-6. For example:
+
+    # This is an H1
+
+    ## This is an H2
+
+    ###### This is an H6
+
+highlighted:
+
+# This is an H1
+
+## This is an H2
+
+###### This is an H6
+
+Optionally, you may "close" atx-style headers. This is purely
+cosmetic -- you can use this if you think it looks better. The
+closing hashes don't even need to match the number of hashes
+used to open the header. (The number of opening hashes
+determines the header level.) :
+
+    # This is an H1 #
+
+    ## This is an H2 ##
+
+    ### This is an H3 ######
+
+
+<h3 id="blockquote">Blockquotes</h3>
+
+Markdown uses email-style `>` characters for blockquoting. If you're
+familiar with quoting passages of text in an email message, then you
+know how to create a blockquote in Markdown. It looks best if you hard
+wrap the text and put a `>` before every line:
+
+    > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+    > consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+    > Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+    > 
+    > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+    > id sem consectetuer libero luctus adipiscing.
+
+> This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+> consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+> Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+> 
+> Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+> id sem consectetuer libero luctus adipiscing.
+
+Markdown allows you to be lazy and only put the `>` before the first
+line of a hard-wrapped paragraph:
+
+    > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+    consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+    Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+
+    > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+    id sem consectetuer libero luctus adipiscing.
+
+Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by
+adding additional levels of `>`:
+
+    > This is the first level of quoting.
+    >
+    > > This is nested blockquote.
+    >
+    > Back to the first level.
+
+renders as:
+
+> This is the first level of quoting.
+>
+> > This is nested blockquote.
+>
+> Back to the first level.
+
+Blockquotes can contain other Markdown elements, including headers, lists,
+and code blocks:
+
+	> ## This is a header.
+	> 
+	> 1.   This is the first list item.
+	> 2.   This is the second list item.
+	> 
+	> Here's some example code:
+	> 
+	>     return shell_exec("echo $input | $markdown_script");
+
+Any decent text editor should make email-style quoting easy. For
+example, with BBEdit, you can make a selection and choose Increase
+Quote Level from the Text menu.

+
+<h3 id="list">Lists</h3>
+
+Markdown supports ordered (numbered) and unordered (bulleted) lists.
+
+Unordered lists use asterisks, pluses, and hyphens -- interchangably
+-- as list markers:
+
+    *   Red
+    *   Green
+    *   Blue
+
+*   Red
+*   Green
+*   Blue
+
+is equivalent to:
+
+    +   Red
+    +   Green
+    +   Blue
+
++   Red
++   Green
++   Blue
+
+and:
+
+    -   Red
+    -   Green
+    -   Blue
+
+-   Red
+-   Green
+-   Blue
+
+Ordered lists use numbers followed by periods:
+
+    1.  Bird
+    2.  McHale
+    3.  Parish
+
+1.  Bird
+2.  McHale
+3.  Parish
+
+It's important to note that the actual numbers you use to mark the
+list have no effect on the HTML output Markdown produces. The HTML
+Markdown produces from the above list is:
+
+    <ol>
+    <li>Bird</li>
+    <li>McHale</li>
+    <li>Parish</li>
+    </ol>
+
+If you instead wrote the list in Markdown like this:
+
+    1.  Bird
+    1.  McHale
+    1.  Parish
+
+or even:
+
+    3. Bird
+    1. McHale
+    8. Parish
+
+you'd get the exact same HTML output. The point is, if you want to,
+you can use ordinal numbers in your ordered Markdown lists, so that
+the numbers in your source match the numbers in your published HTML.
+But if you want to be lazy, you don't have to.
+
+If you do use lazy list numbering, however, you should still start the
+list with the number 1. At some point in the future, Markdown may support
+starting ordered lists at an arbitrary number.
+
+List markers typically start at the left margin, but may be indented by
+up to three spaces. List markers must be followed by one or more spaces
+or a tab.
+
+To make lists look nice, you can wrap items with hanging indents:
+
+    *   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+        Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+        viverra nec, fringilla in, laoreet vitae, risus.
+    *   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+        Suspendisse id sem consectetuer libero luctus adipiscing.
+
+*   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+    Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+    viverra nec, fringilla in, laoreet vitae, risus.
+*   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+    Suspendisse id sem consectetuer libero luctus adipiscing.
+
+But if you want to be lazy, you don't have to:
+
+    *   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+    Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+    viverra nec, fringilla in, laoreet vitae, risus.
+    *   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+    Suspendisse id sem consectetuer libero luctus adipiscing.
+
+If list items are separated by blank lines, Markdown will wrap the
+items in `<p>` tags in the HTML output. For example, this input:
+
+    *   Bird
+    *   Magic
+
+will turn into:
+
+    <ul>
+    <li>Bird</li>
+    <li>Magic</li>
+    </ul>
+
+But this:
+
+    *   Bird
+
+    *   Magic
+
+will turn into:
+
+    <ul>
+    <li><p>Bird</p></li>
+    <li><p>Magic</p></li>
+    </ul>
+
+List items may consist of multiple paragraphs. Each subsequent
+paragraph in a list item must be indented by either 4 spaces
+or one tab:
+
+    1.  This is a list item with two paragraphs. Lorem ipsum dolor
+        sit amet, consectetuer adipiscing elit. Aliquam hendrerit
+        mi posuere lectus.
+
+        Vestibulum enim wisi, viverra nec, fringilla in, laoreet
+        vitae, risus. Donec sit amet nisl. Aliquam semper ipsum
+        sit amet velit.
+
+    2.  Suspendisse id sem consectetuer libero luctus adipiscing.
+
+It looks nice if you indent every line of the subsequent
+paragraphs, but here again, Markdown will allow you to be
+lazy:
+
+    *   This is a list item with two paragraphs.
+
+        This is the second paragraph in the list item. You're
+    only required to indent the first line. Lorem ipsum dolor
+    sit amet, consectetuer adipiscing elit.
+
+    *   Another item in the same list.
+
+To put a blockquote within a list item, the blockquote's `>`
+delimiters need to be indented:
+
+    *   A list item with a blockquote:
+
+        > This is a blockquote
+        > inside a list item.
+
+To put a code block within a list item, the code block needs
+to be indented *twice* -- 8 spaces or two tabs:
+
+    *   A list item with a code block:
+
+            <code goes here>
+
+
+It's worth noting that it's possible to trigger an ordered list by
+accident, by writing something like this:
+
+    1986. What a great season.
+
+In other words, a *number-period-space* sequence at the beginning of a
+line. To avoid this, you can backslash-escape the period:
+
+    1986\. What a great season.
+
+1986\. What a great season.
+
+
+<h3 id="precode">Code Blocks</h3>
+
+Pre-formatted code blocks are used for writing about programming or
+markup source code. Rather than forming normal paragraphs, the lines
+of a code block are interpreted literally. Markdown wraps a code block
+in both `<pre>` and `<code>` tags.
+
+To produce a code block in Markdown, simply indent every line of the
+block by at least 4 spaces or 1 tab. For example, given this input:
+
+    This is a normal paragraph:
+
+        This is a code block.
+
+This is a normal paragraph:
+
+    This is a code block.
+
+Markdown will generate:
+
+    <p>This is a normal paragraph:</p>
+
+    <pre><code>This is a code block.
+    </code></pre>
+
+One level of indentation -- 4 spaces or 1 tab -- is removed from each
+line of the code block. For example, this:
+
+    Here is an example of AppleScript:
+
+        tell application "Foo"
+            beep
+        end tell
+
+will turn into:
+
+    <p>Here is an example of AppleScript:</p>
+
+    <pre><code>tell application "Foo"
+        beep
+    end tell
+    </code></pre>
+
+A code block continues until it reaches a line that is not indented
+(or the end of the article).
+
+Within a code block, ampersands (`&`) and angle brackets (`<` and `>`)
+are automatically converted into HTML entities. This makes it very
+easy to include example HTML source code using Markdown -- just paste
+it and indent it, and Markdown will handle the hassle of encoding the
+ampersands and angle brackets. For example, this:
+
+        <div class="footer">
+            © 2004 Foo Corporation
+        </div>
+
+will turn into:
+
+    <pre><code><div class="footer">
+        &copy; 2004 Foo Corporation
+    </div>
+    </code></pre>
+
+Regular Markdown syntax is not processed within code blocks. E.g.,
+asterisks are just literal asterisks within a code block. This means
+it's also easy to use Markdown to write about Markdown's own syntax.
+
+
+
+<h3 id="hr">Horizontal Rules</h3>
+
+You can produce a horizontal rule tag (`<hr />`) by placing three or
+more hyphens, asterisks, or underscores on a line by themselves. If you
+wish, you may use spaces between the hyphens or asterisks. Each of the
+following lines will produce a horizontal rule:
+
+    * * *
+
+    ***
+
+    *****
+
+    - - -
+
+    ---------------------------------------
+
+highlighted:
+

+
+*****
+
+- - -
+
+---------------------------------------

+
+<h2 id="span">Span Elements</h2>
+
+<h3 id="link">Links</h3>
+
+Markdown supports two style of links: *inline* and *reference*.
+
+In both styles, the link text is delimited by [square brackets].
+
+To create an inline link, use a set of regular parentheses immediately
+after the link text's closing square bracket. Inside the parentheses,
+put the URL where you want the link to point, along with an *optional*
+title for the link, surrounded in quotes. For example:
+
+    This is [an example](http://example.com/ "Title") inline link.
+
+    [This link](http://example.net/) has no title attribute.
+
+This is [an example](http://example.com/ "Title") inline link.
+
+[This link](http://example.net/) has no title attribute.
+
+Will produce:
+
+    <p>This is <a href="http://example.com/" title="Title">
+    an example</a> inline link.</p>
+
+    <p><a href="http://example.net/">This link</a> has no
+    title attribute.</p>
+
+If you're referring to a local resource on the same server, you can
+use relative paths:
+
+    See my [About](/about/) page for details.   
+
+See my [About](/about/) page for details.   
+
+Reference-style links use a second set of square brackets, inside
+which you place a label of your choosing to identify the link:
+
+    This is [an example][id] reference-style link.
+
+This is [an example][id] reference-style link.
+
+You can optionally use a space to separate the sets of brackets:
+
+    This is [an example] [id] reference-style link.
+
+This is [an example] [id] reference-style link.
+
+Then, anywhere in the document, you define your link label like this,
+on a line by itself:
+
+    [id]: http://example.com/  "Optional Title Here"
+
+highlighted:
+
+[id]: http://example.com/  "Optional Title Here"
+
+That is:
+
+*   Square brackets containing the link identifier (optionally
+    indented from the left margin using up to three spaces);
+*   followed by a colon;
+*   followed by one or more spaces (or tabs);
+*   followed by the URL for the link;
+*   optionally followed by a title attribute for the link, enclosed
+    in double or single quotes, or enclosed in parentheses.
+
+The following three link definitions are equivalent:
+
+	[foo]: http://example.com/  "Optional Title Here"
+	[foo]: http://example.com/  'Optional Title Here'
+	[foo]: http://example.com/  (Optional Title Here)
+
+[foo]: http://example.com/  "Optional Title Here"
+[foo]: http://example.com/  'Optional Title Here'
+[foo]: http://example.com/  (Optional Title Here)
+
+**Note:** There is a known bug in Markdown.pl 1.0.1 which prevents
+single quotes from being used to delimit link titles.
+
+The link URL may, optionally, be surrounded by angle brackets:
+
+    [id]: <http://example.com/>  "Optional Title Here"
+
+[id]: <http://example.com/>  "Optional Title Here"
+
+You can put the title attribute on the next line and use extra spaces
+or tabs for padding, which tends to look better with longer URLs:
+
+    [id]: http://example.com/longish/path/to/resource/here
+        "Optional Title Here"
+
+[id]: http://example.com/longish/path/to/resource/here
+    "Optional Title Here"
+
+Link definitions are only used for creating links during Markdown
+processing, and are stripped from your document in the HTML output.
+
+Link definition names may consist of letters, numbers, spaces, and
+punctuation -- but they are *not* case sensitive. E.g. these two
+links:
+
+	[link text][a]
+	[link text][A]
+
+are equivalent.
+
+The *implicit link name* shortcut allows you to omit the name of the
+link, in which case the link text itself is used as the name.
+Just use an empty set of square brackets -- e.g., to link the word
+"Google" to the google.com web site, you could simply write:
+
+	[Google][]
+
+And then define the link:
+
+	[Google]: http://google.com/
+
+Because link names may contain spaces, this shortcut even works for
+multiple words in the link text:
+
+	Visit [Daring Fireball][] for more information.
+
+And then define the link:
+	
+	[Daring Fireball]: http://daringfireball.net/
+
+Link definitions can be placed anywhere in your Markdown document. I
+tend to put them immediately after each paragraph in which they're
+used, but if you want, you can put them all at the end of your
+document, sort of like footnotes.
+
+Here's an example of reference links in action:
+
+    I get 10 times more traffic from [Google] [1] than from
+    [Yahoo] [2] or [MSN] [3].
+
+      [1]: http://google.com/        "Google"
+      [2]: http://search.yahoo.com/  "Yahoo Search"
+      [3]: http://search.msn.com/    "MSN Search"
+
+Using the implicit link name shortcut, you could instead write:
+
+    I get 10 times more traffic from [Google][] than from
+    [Yahoo][] or [MSN][].
+
+      [google]: http://google.com/        "Google"
+      [yahoo]:  http://search.yahoo.com/  "Yahoo Search"
+      [msn]:    http://search.msn.com/    "MSN Search"
+
+Both of the above examples will produce the following HTML output:
+
+    <p>I get 10 times more traffic from <a href="http://google.com/"
+    title="Google">Google</a> than from
+    <a href="http://search.yahoo.com/" title="Yahoo Search">Yahoo</a>
+    or <a href="http://search.msn.com/" title="MSN Search">MSN</a>.</p>
+
+For comparison, here is the same paragraph written using
+Markdown's inline link style:
+
+    I get 10 times more traffic from [Google](http://google.com/ "Google")
+    than from [Yahoo](http://search.yahoo.com/ "Yahoo Search") or
+    [MSN](http://search.msn.com/ "MSN Search").
+
+The point of reference-style links is not that they're easier to
+write. The point is that with reference-style links, your document
+source is vastly more readable. Compare the above examples: using
+reference-style links, the paragraph itself is only 81 characters
+long; with inline-style links, it's 176 characters; and as raw HTML,
+it's 234 characters. In the raw HTML, there's more markup than there
+is text.
+
+With Markdown's reference-style links, a source document much more
+closely resembles the final output, as rendered in a browser. By
+allowing you to move the markup-related metadata out of the paragraph,
+you can add links without interrupting the narrative flow of your
+prose.
+
+
+<h3 id="em">Emphasis</h3>
+
+Markdown treats asterisks (`*`) and underscores (`_`) as indicators of
+emphasis. Text wrapped with one `*` or `_` will be wrapped with an
+HTML `<em>` tag; double `*`'s or `_`'s will be wrapped with an HTML
+`<strong>` tag. E.g., this input:
+
+    *single asterisks*
+
+    _single underscores_
+
+    **double asterisks**
+
+    __double underscores__
+
+will produce:
+
+    <em>single asterisks</em>
+
+    <em>single underscores</em>
+
+    <strong>double asterisks</strong>
+
+    <strong>double underscores</strong>
+
+You can use whichever style you prefer; the lone restriction is that
+the same character must be used to open and close an emphasis span.
+
+Emphasis can be used in the middle of a word:
+
+    un*frigging*believable
+
+un*frigging*believable
+
+But if you surround an `*` or `_` with spaces, it'll be treated as a
+literal asterisk or underscore.
+
+To produce a literal asterisk or underscore at a position where it
+would otherwise be used as an emphasis delimiter, you can backslash
+escape it:
+
+    \*this text is surrounded by literal asterisks\*
+
+\*this text is surrounded by literal asterisks\*
+
+
+
+<h3 id="code">Code</h3>
+
+To indicate a span of code, wrap it with backtick quotes (`` ` ``).
+Unlike a pre-formatted code block, a code span indicates code within a
+normal paragraph. For example:
+
+    Use the `printf()` function.
+
+Use the `printf()` function.
+
+will produce:
+
+    <p>Use the <code>printf()</code> function.</p>
+
+To include a literal backtick character within a code span, you can use
+multiple backticks as the opening and closing delimiters:
+
+    ``There is a literal backtick (`) here.``
+
+``There is a literal backtick (`) here.``
+
+which will produce this:
+
+    <p><code>There is a literal backtick (`) here.</code></p>
+
+The backtick delimiters surrounding a code span may include spaces --
+one after the opening, one before the closing. This allows you to place
+literal backtick characters at the beginning or end of a code span:
+
+	A single backtick in a code span: `` ` ``
+	
+	A backtick-delimited string in a code span: `` `foo` ``
+
+A single backtick in a code span: `` ` ``
+
+A backtick-delimited string in a code span: `` `foo` ``
+
+will produce:
+
+	<p>A single backtick in a code span: <code>`</code></p>
+	
+	<p>A backtick-delimited string in a code span: <code>`foo`</code></p>
+
+With a code span, ampersands and angle brackets are encoded as HTML
+entities automatically, which makes it easy to include example HTML
+tags. Markdown will turn this:
+
+    Please don't use any `<blink>` tags.
+
+Please don't use any `<blink>` tags.
+
+into:
+
+    <p>Please don't use any <code><blink></code> tags.</p>
+
+You can write this:
+
+    `—` is the decimal-encoded equivalent of `—`.
+
+`—` is the decimal-encoded equivalent of `—`.
+
+to produce:
+
+    <p><code>&#8212;</code> is the decimal-encoded
+    equivalent of <code>&mdash;</code>.</p>
+
+
+
+<h3 id="img">Images</h3>
+
+Admittedly, it's fairly difficult to devise a "natural" syntax for
+placing images into a plain text document format.
+
+Markdown uses an image syntax that is intended to resemble the syntax
+for links, allowing for two styles: *inline* and *reference*.
+
+Inline image syntax looks like this:
+
+    ![Alt text](/path/to/img.jpg)
+
+    ![Alt text](/path/to/img.jpg "Optional title")
+
+![Alt text](/path/to/img.jpg)
+
+![Alt text](/path/to/img.jpg "Optional title")
+
+That is:
+
+*   An exclamation mark: `!`;
+*   followed by a set of square brackets, containing the `alt`
+    attribute text for the image;
+*   followed by a set of parentheses, containing the URL or path to
+    the image, and an optional `title` attribute enclosed in double
+    or single quotes.
+
+Reference-style image syntax looks like this:
+
+    ![Alt text][id]
+
+Where "id" is the name of a defined image reference. Image references
+are defined using syntax identical to link references:
+
+    [id]: url/to/image  "Optional title attribute"
+
+As of this writing, Markdown has no syntax for specifying the
+dimensions of an image; if this is important to you, you can simply
+use regular HTML `<img>` tags.
+
+
+* * *
+
+
+<h2 id="misc">Miscellaneous</h2>
+
+<h3 id="autolink">Automatic Links</h3>
+
+Markdown supports a shortcut style for creating "automatic" links for URLs and email addresses: simply surround the URL or email address with angle brackets. What this means is that if you want to show the actual text of a URL or email address, and also have it be a clickable link, you can do this:
+
+    <http://example.com/>
+
+<http://example.com/>
+    
+Markdown will turn this into:
+
+    <a href="http://example.com/">http://example.com/</a>
+
+Automatic links for email addresses work similarly, except that
+Markdown will also perform a bit of randomized decimal and hex
+entity-encoding to help obscure your address from address-harvesting
+spambots. For example, Markdown will turn this:
+
+    <address at example.com>
+
+<address at example.com>
+
+into something like this:
+
+    <a href="&#x6D;&#x61;i&#x6C;&#x74;&#x6F;:&#x61;&#x64;&#x64;&#x72;&#x65;
+    ss@ex&#x61;m&#x70;&#x6C;e&#x2E;co
+    m">&#x61;&#x64;&#x64;&#x72;&#x65;ss@ex&#x61;
+    m&#x70;&#x6C;e&#x2E;com</a>
+
+which will render in a browser as a clickable link to "address at example.com".
+
+(This sort of entity-encoding trick will indeed fool many, if not
+most, address-harvesting bots, but it definitely won't fool all of
+them. It's better than nothing, but an address published in this way
+will probably eventually start receiving spam.)
+
+
+
+<h3 id="backslash">Backslash Escapes</h3>
+
+Markdown allows you to use backslash escapes to generate literal
+characters which would otherwise have special meaning in Markdown's
+formatting syntax. For example, if you wanted to surround a word
+with literal asterisks (instead of an HTML `<em>` tag), you can use
+backslashes before the asterisks, like this:
+
+    \*literal asterisks\*
+
+Markdown provides backslash escapes for the following characters:
+
+    \   backslash
+    `   backtick
+    *   asterisk
+    _   underscore
+    {}  curly braces
+    []  square brackets
+    ()  parentheses
+    #   hash mark
+	+	plus sign
+	-	minus sign (hyphen)
+    .   dot
+    !   exclamation mark
+
+extensions:
+
+``` ruby
+puts @foo
+```

+Informatik und Informationsgesellschaft I: Digitale Medien (32 214)
+Computer lassen ihre eigentliche Bestimmung durch Multimedia und Vernetzung erkennen: Es sind digitale Medien, die alle bisherigen Massen- und Kommunikationsmedien simulieren, kopieren oder ersetzen können. Die kurze Geschichte elektronischer Medien vom Telegramm bis zum Fernsehen wird so zur Vorgeschichte des Computers als Medium. Der Prozess der Mediatisierung der Rechnernetze soll in Technik, Theorie und Praxis untersucht werden. Das PR soll die Techniken der ortsverteilten und zeitversetzten Lehre an Hand praktischer Übungen vorführen und untersuchen.

+;;; of M and, if it is not found there, try each of the modules in the
+;;; uses list of M.  This is the normal way of testing for some
+;;; property, so we state these properties without qualification as
+;;; in: ``The symbol 'fnord is interned in module M because it is
+;;; interned locally in module M2 which is a member of the uses list
+;;; of M.''

+
+;; module-search fn m

+# sokoban.sed  <http://aurelio.net/sed/sokoban>
+#   by Aurelio Marinho Jargas <verde (a) aurelio net>
+#
+# Motivated by reading the amazing Adventure (Colossal Cave) history
+#      <http://www.rickadams.org/adventure/a_history.html>
+# GPL levels took from Mike Sharpe's sokoban.vim <http://vim.sourceforge.net>
+#
+# IMPORTANT
+# This script has terminal control chars, so you must DOWNLOAD this
+# file. Just copy/paste or printing it to a file (lynx) will NOT work.
+#
+# THE GAME
+# You know sokoban. Everybody knows sokoban.
+# Right, if you don't, it's a box pushing game. You have a mess, boxes
+# all over the room and must place them on the boxes place. To move a
+# box you must push it. You can only push a box if the path is clear
+# with no wall or other box on the way (You are not that strong).
+#
+#   COMMANDS                       MOVING AROUND
+#     :q   quit                      h or <left-arrow>  - move left
+#     :r   restart level             j or <down-arrow>  - move down
+#     :z   refresh screen            k or <up-arrow>    - move up
+#     :gN  go to level N             l or <right-arrow> - move right
+#
+#   ACTORS
+#     o box                  % wall
+#     . box place            @ you
+#     O box placed right     ! you over a box place
+#
+#
+# RUNNING
+# prompt$ ./sokoban.sed <enter>
+# <enter>
+# 1
+# Now just move! (:q quits)
+#
+# DETAILS
+# It's all written in SED, so we've got some limitations:
+# - As a line-oriented editor, you MUST hit <ENTER> after *any* move.
+#   Yes, that sucks. But you can accumulate various movements and hit
+#   <ENTER> just once.
+# - When you run sokoban.sed, you must first press any key to feed SED
+#   and then you'll see the welcome message.
+# - If your sed is not on /bin, edit the first line of this script,
+#   or call it as: sed -nf sokoban.sed 
+# - This script is 'sedcheck' <http://lvogel.free.fr/sed/sedcheck.sed>
+#   compliant, so it must run fine in *any* SED version
+#
+# And always remember, it's cool because it's SED. If you don't like it
+# you can try xsokoban instead <http://www.cs.cornell.edu/andru/xsokoban.html>
+#

+Generator comment:
+'A Generator object provides a way to define a Generator method: such
+a method does not return a single value, instead it returns an object
+(the Generator) that uses a Stream interface to access multiple
+return values.  The return values are computed one at a time, as
+needed, and hence need not even be finite.
+
+A generator methods starts by creating a Generator object with
+"Generator new" and saving it into a temporary variable.  As soon as
+this is executed, even though it is not apparent, the method exits
+returning the newly created Generator.  As soon as a message like
+#next, #peek, #atEnd or #peekFor: is sent to the generator, execution
+of the method that created it resumes and goes on until the
+generator''s #yield: method is called: then the argument of #yield:
+will be the Generator''s next element.  If the generator method goes
+on to the end without calling #yield:, the Generator will produce no
+more elements and #atEnd will return true.
+
+Alternatively, a generator block can be converted to a Generator with
+"Generator on: [...]".  The Generator itself is passed to the block
+and, again, the block starts its execution when a message like
+#next, #peek, #atEnd or #peekFor: is sent to the generator.  Again,
+the block''s execution is temporarily suspended when the
+generator''s #yield: method is called.
+
+Returning a value from the generator method makes no sense at least
+after "Generator new" is invoked.  Before, you can use it to return a
+different kind of Stream, or nil, or whatever else; after, the value
+returned will not matter and the return will put an end to the
+Generator''s production of elements.
+
+You could achieve the effect of generators manually by writing your
+own class and storing all the local variables of the generator as
+instance variables.  For example, returning a list of integers could
+be done by setting a variable to 0, and having the #next method
+increment it and return it.  However, for a moderately complicated
+generator, writing a corresponding class would be much messier (and
+might lead to code duplication or inefficiency if you want to support
+#peek, #peekFor: and/or #atEnd): in general, providing a #do:-like
+interface is easy, but not providing a Stream-like one (think binary
+trees).
+
+The idea of generators comes from other programming languages, in
+particular this interface looks much like Scheme streams and Python
+generators.  But Python in turn mutuated the idea for example from
+Icon, where the idea of generators is central.  In Icon, every
+expression and function call behaves like a generator, and if a
+statement manages scalars, it automatically uses up all the results
+that the corresponding generator provides; on the other hand, Icon
+does not represent generators as first-class objects like Python and
+Smalltalk do.'!

+\centerline{\sc \large A Simple Sample \LaTeX\ File}
+\vspace{.5pc}
+\centerline{\sc Stupid Stuff I Wish Someone Had Told Me Four Years Ago}
+\centerline{\it (Read the .tex file along with this or it won't 
+            make much sense)}
+\vspace{2pc}
+
+The first thing to realize about \LaTeX\ is that it is not ``WYSIWYG''. 
+In other words, it isn't a word processor; what you type into your 
+.tex file is not what you'll see in your .dvi file.  For example, 
+\LaTeX\ will      completely     ignore               extra
+spaces    within                             a line of your .tex file.
+Pressing return
+in 
+the 
+middle 
+of
+a
+line
+will not register in your .dvi file. However, a double carriage-return
+is read as a paragraph break.
+
+Like this.  But any carriage-returns after the first two will be 
+completely ignored; in other words, you 
+
+
+can't 
+
+add
+
+
+
+
+
+
+more 
+
+
+
+
+space 
+
+
+between 
+
+
+
+
+lines, no matter how many times you press return in your .tex file.
+
+In order to add vertical space you have to use ``vspace''; for example, 
+you could add an inch of space by typing \verb|\vspace{1in}|, like this:
+\vspace{1in}
+
+To get three lines of space you would type \verb|\vspace{3pc}|
+(``pc'' stands for ``pica'', a font-relative size), like this:
+\vspace{3pc}
+
+Notice that \LaTeX\ commands are always preceeded by a backslash.  
+Some commands, like \verb|\vspace|, take arguments (here, a length) in
+curly brackets.  
+
+The second important thing to notice about \LaTeX\ is that you type 
+in various ``environments''...so far we've just been typing regular 
+text (except for a few inescapable usages of \verb|\verb| and the
+centered, smallcaps, large title).  There are basically two ways that 
+you can enter and/or exit an environment;
+\vspace{1pc}
+
+\centerline{this is the first way...}
+
+\begin{center}
+this is the second way.
+\end{center}
+
+\noindent Actually there is one more way, used above; for example, 
+{\sc this way}.  The way that you get in and out of environment varies
+depending on which kind of environment you want; for example, you use 
+\verb|\underline| ``outside'', but \verb|\it| ``inside''; 
+notice \underline{this} versus {\it this}.
+
+The real power of \LaTeX\ (for us) is in the math environment. You 
+push and pop out of the math environment by typing \verb|$|. For 
+example, $2x^3 - 1 = 5$ is typed between dollar signs as
+\verb|$2x^3 - 1 = 5$|. Perhaps a more interesting example is
+$\lim_{N \to \infty} \sum_{k=1}^N f(t_k) \Delta t$.
+
+You can get a fancier, display-style math 
+environment by enclosing your equation with double dollar signs.  
+This will center your equation, and display sub- and super-scripts in 
+a more readable fashion:
+
+$$\lim_{N \to \infty} \sum_{k=1}^N f(t_k) \Delta t.$$
+
+If you don't want your equation to be centered, but you want the nice 
+indicies and all that, you can use \verb|\displaystyle| and get your 
+formula ``in-line''; using our example this is 
+$\displaystyle \lim_{N \to \infty} \sum_{k=1}^N f(t_k) \Delta t.$  Of 
+course this can screw up your line spacing a little bit.
+
+There are many more things to know about \LaTeX\ and we can't 
+possibly talk about them all here.
+You can use \LaTeX\ to get tables, commutative diagrams, figures, 
+aligned equations, cross-references, labels, matrices, and all manner 
+of strange things into your documents.  You can control margins, 
+spacing, alignment, {\it et cetera} to higher degrees of accuracy than 
+the human eye can percieve.  You can waste entire days typesetting 
+documents to be ``just so''.  In short, \LaTeX\ rules.
+
+The best way to learn \LaTeX\ is by example. Get yourself a bunch
+of .tex files, see what kind of output they produce, and figure out how
+to modify them to do what you want.  There are many template and 
+sample files on the department \LaTeX\ page and in real life in the 
+big binder that should be in the computer lab somewhere.  Good luck!

+"   - Class aware completion:
+"      a) caching?
+"   - Switching to HTML (XML?) completion (SQL) inside of phpStrings
+"   - allow also for XML completion <- better do html_flavor for HTML
+"     completion
+"   - outside of <?php?> getting parent tag may cause problems. Heh, even in

+# Rubame
+
+Rubame is a simple Ruby websocket game server.  I was originally using EventMachine for a private project, but it became apparent that EM may not be the most suitable tool.  EM is designed (as I understand it) for servers that will handle lots of low duration connections, whereas my project will involve only a small handful (between 1 and 20, likely) that are long lasting.  However, the primary concern I had was how EM takes over the thread.  In order to have game logic run, it seemed the options were to create a new thread, or use periodic timers to have a game loop called.
+
+Neither seemed ideal, and I wanted to have more control in order to better manage cpu usage.  Rubame allows me to run the network loop when it suits me, allowing the game logic/engine to be the primary tool.
+
+Rubame makes use of [WebSocket Ruby](https://github.com/imanel/websocket-ruby) to handle the websocket protocol, and the standard ruby sockets libraries for the actual network connections.
+
+I am by no means a Ruby expert, so I expect there to be many ways I could improve this.  I also expect there are ways I have done this that will make someone proficient in Ruby cringe.  If you have such comments, please [email me](mailto:me at marksaward.com).  I also expect to improve the code as my project progresses, and my needs grow.  However, I will keep improvements to only be those that are of general use, and not specific to my project.
+
+## Example Use
+
+```ruby
+require 'rubame'
+
+server = Rubame::Server.new("0.0.0.0", 25252)
+while true
+  server.run do |client|
+    client.onopen do
+      puts "Server reports:  client open"
+    end
+    client.onmessage do |mess|
+      puts "Server reports:  message received: #{mess}"
+      client.send "You sent me #{mess}"
+    end
+    client.onclose do
+      puts "Server reports:  client closed"
+    end
+  end
+end
+```
+
+A useful Chrome plugin to help test connections is this [Simple Websocket Client](https://chrome.google.com/webstore/detail/simple-websocket-client/pfdhoblngboilpfeibdedpjgfnlcodoo).
+
+Each time the loop is run, it checks with ruby IO to see if any sockets have any new data.  It then reads up to (currently) 2000 bytes from that socket.  If there is more data than that waiting, it will have to wait until the next time the loop is called.  Once enough data has been received for a complete frame, that frame will be read and returned as a message, via client.onmessage as seen in the example.
+
+## Possible Future Features
+
+* Binary data - Currently, Rubame only deals with text network traffic.  This is not ideal, and so I hope to add the ability to send binary data, along with examples here showing how to communicate with a javascript client.
+* Lazy send - Currently, Rubame sends a message as soon as the message is requested to be sent.  Sometimes, a game may want to send some traffic whenever it is convenient, and some traffic immediately.  I may add the ability to lazy send data.
+
+__Please Note:__ The lazy send code currently is broken, so do not use it!
+
+## RSpec
+
+The RSpec is quite incomplete for now.  I expect to add more tests later.

+CoreAudio (Audio Framework of Mac OS X) wrapper library for ruby 1.9
+
+== Features
+* HAL (Hardware Abstraction Layer) wrapper
+* Detect audio devices
+* Get/Set device properties (numbers of channels, sample rate, frame size...)
+* Output audio data (Loop buffer, Stream buffer)
+* Input audio data (Stream buffer)
+* Save audio data to WAV/M4A file (wrapper for ExtAudioFile)
+* Ream audio file (WAV/M4A)
+
+== ToDo
+* Wrapper for AudioUnit/AudioGraph
+
+== Contributing to coreaudio
+
+* Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
+* Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
+* Fork the project
+* Start a feature/bugfix branch
+* Commit and push until you are happy with your contribution
+* Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
+* Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.

+* On Windows use GetProcessTimes to return real PROCESS_TIME times instead of wall times (Charlie Savage).
+* Split out tests for each time of measurement (cpu_time, process_time, etc.) (Charlie Savage).
+* Dropped support for Ruby 1.8.4 and 1.8.6 and 1.9.0 (Charlie Savage).
+* Added support for sorting results by total, self, wait and child times (Jan Suchal)
+* Added tests for sorting behaviour & removed options from constructor to print method (Jan Suchal)
+* Fix line number tests due to changes at top of file (Charlie Savage).
+* Add encoding statement to top of all files for Ruby 1.9.x compatability (Charlie Savage).
+* Add def file for VC to avoid the whole declspec annoyance (Charlie Savage).
+* Update test suite to ensure current working directory is correct (Charlie Savage).
+* Modernize gem file and remove various custom/home grown solutions that aren't needed anymore (Charlie Savage).
+* Remove custom mingw build scripts, use rake compiler instead  (Charlie Savage).
+* Fixes for compiling with VC 2010 (Charlie Savage).

+
+0.7.3 (2008-12-09)
+========================
+* Fixed compile error with new x86_64 code using GCC.
+
+0.7.2 (2008-12-08)
+========================
+* Fixed major bug in printing child methods in graph reports.
+
+* Fixes for supporting x86_64 machines (Diego Pettenò)
+
+
+0.7.1 (2008-11-28)
+========================
+* Added new AggregateCallInfo class for printers to
+  make results easier to read.  Take this call sequence
+  for example:
+
+   A   B   C
+   |   |   |
+   Z   A   A
+       |   |
+       Z   Z
+
+  By default, ruby-prof will show that Z was called by 3 separate
+  instances of A.  In an IDE that is helpful but in a text report
+  it is not since it makes the report much harder to read.
+  As a result, printers now aggregate together callers (and children),
+  matching ruby-prof's output from versions prior to 0.7.0.
+
+* Fixes for supporting x86_64 machines (Matt Sanford)
+
+
+0.7.0 (2008-11-04)
+========================
+
+Features
+--------
+* Added two new methods - RubyProf.resume and RubyProf.pause.
+  RubyProf.resume takes an optional block, which ensures that
+  RubyProf.pause is called.  For example:
+
+  10.times do |i|
+    RubyProf.resume do
+      # Some long process
+    end
+  end
+
+  result = RubyProf.stop
+
+* Added support for profiling tests that use Ruby's built-in
+  unit test framework (ie, test derived from
+  Test::Unit::TestCase).  To enable profiling simply add
+  the following line of code to your test class:
+
+    include RubyProf::Test
+
+  By default, profiling results are written to the current
+  processes working directory.  To change this, or other
+  profiling options, simply modify the PROFILE_OPTIONS hash
+  table as needed.
+
+* Used the new support for profiling test cases to revamp
+  the way that Rails profiling works.  For more information
+  please refer to RubyProf's documentation.
+
+* Keep track of call stack for each method to enable more
+  powerful profile visualizations in Integrated Development
+  Environments (Hin Boean, work supported by CodeGear).
+
+* Expose measurements to Ruby (Jeremy Kemper).
+
+* Add support for additional memory measurements modes in Ruby 1.9 (Jeremy Kemper).
+
+* Add support for Lloyd Hilaiel's Ruby patch for measuring total heap size.
+   See http://lloydforge.org/projects/ruby. (Jeremy Kemper).
+
+
+Fixes
+-------
+* RubyProf.profile no longer crashes if an exception is
+  thrown during a profiling run.
+
+* Measure memory in fractional kilobytes rather than rounding down (Jeremy Kemper)

+  due to the conversion to doubles (Sylvain Joyeux)
+* Changed constant ALLOCATED_OBJECTS to ALLOCATIONS in the C code to
+  match the Ruby code (Sylvain Joyeux)
+* Added support for calltree printer to ruby-prof binary script (Sylvain Joyeux)
+* Fix support for the allocator measure mode to extconf.rb (Sylvain Joyeux)
+* Honor measure mode when specified on the command line (Sylvain Joyeux)
+* Sorting of methods by total time was incorrect (Dan Fitch, Charlie Savage)
+* Fix ruby-prof to work with the latest version of GEMS (Alexander Dymo)

+
+== Overview
+
+ruby-prof is a fast code profiler for Ruby.  Its features include:
+
+* Speed - it is a C extension and therefore many times faster than the standard Ruby profiler.
+* Modes - Ruby prof can measure a number of different parameters, including call times, memory usage and object allocations.
+* Reports - can generate text and cross-referenced html reports
+  - Flat Profiles - similar to the reports generated by the standard Ruby profiler
+  - Graph profiles - similar to GProf, these show how long a method runs, which methods call it and which methods it calls.
+  - Call tree profiles - outputs results in the calltree format suitable for the KCacheGrind profiling tool.
+  - Many more -- see reports section of this README.
+* Threads - supports profiling multiple threads simultaneously
+
+== Requirements
+
+ruby-prof requires Ruby 1.9.3 or higher. Please note some ruby
+releases have known bugs which cause ruby-prof problems, like
+incorrect measurements. We suggest to use the latest minor patch level
+release if possible. In particular, on the 2.1 branch of ruby you
+should use 2.1.5.
+
+If you are running Linux or Unix you'll need a C compiler so the extension
+can be compiled when it is installed.
+
+If you are running Windows, then you may need to install the
+Windows specific RubyGem which includes an already built extension (see Install section).
+
+== Install
+
+The easiest way to install ruby-prof is by using Ruby Gems.  To install:
+
+  gem install ruby-prof
+
+If you're on windows then please install the devkit first so that it can compile.
+
+== Usage
+
+There are two ways of running ruby-prof, via the command line or via its API.
+
+=== ruby-prof executable
+
+The first is to use ruby-prof to run the Ruby program you want to
+profile. For more information refer to the documentation of the
+ruby-prof command.
+
+
+=== ruby-prof API
+
+The second way is to use the ruby-prof API to profile
+particular segments of code.
+
+  require 'ruby-prof'
+
+  # Profile the code
+  RubyProf.start
+  ...
+  [code to profile]
+  ...
+  result = RubyProf.stop
+
+  # Print a flat profile to text
+  printer = RubyProf::FlatPrinter.new(result)
+  printer.print(STDOUT)
+
+Alternatively, you can use a block to tell ruby-prof what
+to profile:
+
+  require 'ruby-prof'
+
+  # Profile the code
+  result = RubyProf.profile do
+    ...
+    [code to profile]
+    ...
+  end
+
+  # Print a graph profile to text
+  printer = RubyProf::GraphPrinter.new(result)
+  printer.print(STDOUT, {})
+
+ruby-prof also supports pausing and resuming profiling runs.
+
+  require 'ruby-prof'
+
+  # Profile the code
+  RubyProf.start
+  [code to profile]
+  RubyProf.pause
+  [other code]
+  RubyProf.resume
+  [code to profile]
+  result = RubyProf.stop
+
+Note that resume will automatically call start if a profiling run
+has not yet started.  In addition, resume can also take a block:
+
+  require 'ruby-prof'
+
+  # Profile the code
+  RubyProf.resume do
+    [code to profile]
+  end
+
+  data = RubyProf.stop
+
+With this usage, resume will automatically call pause at the
+end of the block.
+
+
+== Method and Thread Elimination
+
+ruby-prof supports eliminating specific methods and threads from profiling
+results. This is useful for reducing connectivity in the call graph, making it easier to
+identify the source of performance problems when using a graph printer.
+
+For example, consider Integer#times: it's hardly ever useful to know how much time is
+spent in the method itself. We're much more interested in how much the passed in block
+contributes to the time spent in the method which contains the Integer#times call.
+
+Methods are eliminated from the collected data by calling `eliminate_methods!` on the
+profiling result, before submitting it to a printer.
+
+  result = RubyProf.stop
+  result.eliminate_methods!([/Integer#times/])
+
+The argument given to `eliminate_methods!` is either an array of regular expressions, or
+the name of a file containing a list of regular expressions (line separated text).
+
+After eliminating methods the resulting profile will appear exactly as if those methods
+had been inlined at their call sites.
+
+In a similar manner, threads can be excluded so they are not profiled at all.  To do this,
+pass an array of threads to exclude to ruby-prof:
+
+  RubyProf::exclude_threads = [ thread2 ]
+  RubyProf.start
+
+Note that the excluded threads must be specified *before* profiling.
+
+
+== Benchmarking full load time including rubygems startup cost
+
+If you want to get a more accurate measurement of what takes all of a gem's bin/xxx
+command to load, you may want to also measure rubygems' startup penalty.
+You can do this by calling into bin/ruby-prof directly, ex:
+
+  $ gem which ruby-prof
+  g:/192/lib/ruby/gems/1.9.1/gems/ruby-prof-0.10.2/lib/ruby-prof.rb
+
+now run it thus (substitute lib/ruby-prof.rb with bin/ruby-prof):
+
+  $ ruby g:/192/lib/ruby/gems/1.9.1/gems/ruby-prof-0.10.2/bin/ruby-prof g:\192\bin\some_installed_gem_command
+
+or
+
+  $ ruby g:/192/lib/ruby/gems/1.9.1/gems/ruby-prof-0.10.2/bin/ruby-prof ./some_file_that_does_a_require_rubygems_at_the_beginning.rb
+
+
+== Profiling Rails
+
+To profile a Rails application it is vital to run it using production like
+settings (cache classes, cache view lookups, etc.).  Otherwise, Rail's
+dependency loading code will overwhelm any time spent in the application
+itself (our tests show that Rails dependency loading causes a roughly 6x
+slowdown).  The best way to do this is create a new Rails environment,
+profile.rb.
+
+So to profile Rails:
+
+1.  Create a new profile.rb environment.  Make sure to turn on cache_classes
+    and cache_template_loading.  Otherwise your profiling results will be
+    overwhelemed by the time Rails spends loading required files.  You should
+    likely turn off caching.
+
+2.  Add the ruby-prof to your gemfile:
+
+      group :profile do
+        gem 'ruby-prof'
+      end
+
+3.  Add the ruby prof rack adapter to your middleware stack.  One way to
+    do this is by adding the following code to config.ru:
+
+      if Rails.env.profile?
+        use Rack::RubyProf, :path => '/temp/profile'
+      end
+
+    The path is where you want profiling results to be stored.  By default the
+    rack adapter will generate a html call graph report and flat text report.
+
+4.  Now make a request to your running server.  New profiling information will
+    be generated for each request.  Note that each request will overwrite
+    the profiling reports created by the previous request!
+
+== Reports
+
+ruby-prof can generate a number of different reports:
+
+* Flat Reports
+* Graph Reports
+* HTML Graph Reports
+* Call graphs
+* Call stack reports
+* More!
+
+Flat profiles show the overall time spent in each method. They
+are a good way of quickly identifying which methods take the most time.
+An example of a flat profile and an explanation can be found in
+{examples/flat.txt}[http://github.com/ruby-prof/ruby-prof/tree/master/examples/flat.txt].
+
+There are several varieties of these -- run $ ruby-prof --help
+
+Graph profiles also show the overall time spent in each method. In
+addition, they also show which methods call the current method and which
+methods its calls.  Thus they are good for understanding how methods
+gets called and provide insight into the flow of your program. An
+example text graph profile is located at
+{examples/graph.txt}[http://github.com/ruby-prof/ruby-prof/tree/master/examples/graph.txt].
+
+HTML Graph profiles are the same as graph profiles, except output is
+generated in hyper-linked HTML. Since graph profiles can be quite large,
+the embedded links make it much easier to navigate the results. An
+example html graph profile is located at
+{examples/graph.html}[http://github.com/ruby-prof/ruby-prof/tree/master/examples/graph.html].
+
+Call graphs output results in the calltree profile format which is used
+by KCachegrind. Call graph support was generously donated by Carl
+Shimer. More information about the format can be found at the
+{KCachegrind}[http://kcachegrind.sourceforge.net/cgi-bin/show.cgi/KcacheGrindCalltreeFormat]
+site.
+
+Call stack reports produce a HTML visualization of the time spent in
+each execution path of the profiled code. An example can be found at
+{examples/stack.html}[http://github.com/ruby-prof/ruby-prof/tree/master/examples/stack.html].
+
+Another good example: [http://twitpic.com/28z94a]
+
+Finally, there's a so called MultiPrinter which can generate several
+reports in one profiling run. See
+{examples/multi.stack.html}[http://github.com/ruby-prof/ruby-prof/tree/master/examples/multi.stack.html].
+
+There is also a graphviz .dot visualiser.
+
+== Printers
+
+Reports are created by printers.  Supported printers include:
+
+* RubyProf::FlatPrinter - Creates a flat report in text format
+* RubyProf::FlatPrinterWithLineNumbers - same as above but more verbose
+* RubyProf::GraphPrinter - Creates a call graph report in text format
+* RubyProf::GraphHtmlPrinter - Creates a call graph report in HTML (separate files per thread)
+* RubyProf::DotPrinter - Creates a call graph report in GraphViz's DOT format which can be converted to an image
+* RubyProf::CallTreePrinter - Creates a call tree report compatible with KCachegrind.
+* RubyProf::CallStackPrinter - Creates a HTML visualization of the Ruby stack
+* RubyProf::MultiPrinter - Uses the other printers to create several reports in one profiling run
+* More!
+
+To use a printer:
+
+  ...
+  result = RubyProf.stop
+  printer = RubyProf::GraphPrinter.new(result)
+  printer.print(STDOUT, :min_percent => 2)
+
+The first parameter is any writable IO object such as STDOUT or a file.
+The second parameter, specifies the minimum percentage a method must take
+to be printed.  Percentages should be specified as integers in the range 0 to 100.
+For more information please see the documentation for the different printers.
+
+The other option is :print_file => true (default false), which adds the filename to the
+output (GraphPrinter only).
+
+The MultiPrinter differs from the other printers in that it requires a directory path
+and a basename for the files it produces.
+
+   printer = RubyProf::MultiPrinter.new(result)
+   printer.print(:path => ".", :profile => "profile")
+
+
+== Measurements
+
+Depending on the mode and platform, ruby-prof can measure various
+aspects of a Ruby program.  Supported measurements include:
+
+* wall time (RubyProf::WALL_TIME)
+* process time (RubyProf::PROCESS_TIME)
+* cpu time (RubyProf::CPU_TIME)
+* object allocations (RubyProf::ALLOCATIONS)
+* memory usage (RubyProf::MEMORY)
+* garbage collection time (RubyProf::GC_TIME)
+* garbage collections runs (RubyProf::GC_RUNS)
+
+Wall time measures the real-world time elapsed between any two moments.
+If there are other processes concurrently running on the system
+that use significant CPU or disk time during a profiling run
+then the reported results will be larger than expected.
+
+Process time measures the time used by a process between any two moments.
+It is unaffected by other processes concurrently running
+on the system. Note that Windows does not support measuring process
+times.
+
+CPU time uses the CPU clock counter to measure time.  The returned
+values are dependent on the correctly setting the CPU's frequency.
+This mode is only supported on Pentium or PowerPC platforms (linux only).
+
+Object allocation reports show how many objects each method in
+a program allocates.  This support was added by Sylvain Joyeux
+and requires a patched Ruby interpreter. See below.
+
+Memory usage reports show how much memory each method in a program
+uses.  This support was added by Alexander Dymo and requires a
+patched Ruby interpreter. See below.
+
+Garbage collection time reports how much time is spent in Ruby's
+garbage collector during a profiling session. This support was added
+by Jeremy Kemper and requires a patched Ruby interpreter. See below.
+
+Garbage collection runs report how many times Ruby's garbage collector
+is invoked during a profiling session. This support was added by
+Jeremy Kemper and requires a patched Ruby interpreter. See below.
+
+Ruby patches: all of the patches to Ruby are included in the
+railsexpress patchsets for rvm, see https://github.com/skaes/rvm-patchsets
+
+To set the measurement:
+
+* RubyProf.measure_mode = RubyProf::WALL_TIME
+* RubyProf.measure_mode = RubyProf::PROCESS_TIME
+* RubyProf.measure_mode = RubyProf::CPU_TIME
+* RubyProf.measure_mode = RubyProf::ALLOCATIONS
+* RubyProf.measure_mode = RubyProf::MEMORY
+* RubyProf.measure_mode = RubyProf::GC_TIME
+* RubyProf.measure_mode = RubyProf::GC_RUNS
+
+The default value is RubyProf::WALL_TIME.
+
+You may also specify the measure_mode by using the RUBY_PROF_MEASURE_MODE
+environment variable:
+
+* export RUBY_PROF_MEASURE_MODE=wall
+* export RUBY_PROF_MEASURE_MODE=process
+* export RUBY_PROF_MEASURE_MODE=cpu

+
+On Linux, process time is measured using the clock method provided
+by the C runtime library. Note that the clock method does not
+report time spent in the kernel or child processes and therefore
+does not measure time spent in methods such as Kernel.sleep method.
+If you need to measure these values, then use wall time.  Wall time
+is measured using the gettimeofday kernel method.
+
+If you set the clock mode to PROCESS_TIME, then timings are read using
+the clock method provided by the C runtime library.  Note though,
+these values are wall times on Windows and not process times like on
+Linux.  Wall time is measured using the GetLocalTime API.
+
+If you use wall time, the results will be affected by other
+processes running on your computer, network delays, disk access,
+etc.  As result, for the best results, try to make sure your
+computer is only performing your profiling run and is
+otherwise quiescent.
+
+== Multi-threaded Applications
+
+Unfortunately, Ruby does not provide an internal api
+for detecting thread context switches in 1.8.  As a result, the
+timings ruby-prof reports for each thread may be slightly
+inaccurate.  In particular, this will happen for newly
+spawned threads that go to sleep immediately (their first call).
+For instance, if you use Ruby's timeout library to wait for 2 seconds,
+the 2 seconds will be assigned to the foreground thread
+and not the newly created background thread.  These errors
+can largely be avoided if the background thread performs any
+operation before going to sleep.
+
+== Performance
+
+Significant effort has been put into reducing ruby-prof's overhead
+as much as possible.  Our tests show that the overhead associated
+with profiling code varies considerably with the code being
+profiled.  Most programs will run approximately twice as slow
+while highly recursive programs (like the fibonacci series test)
+will run three times slower.

+
+All values are in seconds. 
+
+The columns are:
+
+	%self        - The percentage of time spent in this method, derived from self_time/total_time
+	cumulative   - The sum of the time spent in this method and all the methods listed above it.
+	total        - The time spent in this method and its children.
+	self         - The time spent in this method.
+	children     - The time spent in this method's children.
+	calls        - The number of times this method was called.
+	self/call    - The average time spent per call in this method.
+  total/call   - The average time spent per call in this method and its children.
+  name         - The name of the method.
+
+Methods are sorted based on %self, therefore the methods that execute the longest are listed
+first.
+
+The interpretation of method names is:
+* #toplevel - The root method that calls all other methods
+* MyObject#test - An instance method "test" of the class "MyObject"
+* <Object:MyObject>#test - The <> characters indicate a singleton method on a singleton class.
+
+For example, wee can see that Integer#upto took the most time, 4.06 seconds.  An additional
+4.66 seconds were spent in its children, for a total time of 8.72 seconds.

+<h1> Graph Profile</h1>
+<p>Graph profiles show how long each method runs, which methods call it
+  and which methods it calls. To understand how to read a graph profile, refer to
+   the <a href="graph.txt">documentation</a> for the text graph report. </p>
+<p>The main advantage of an HTML graph format versus the text format is the use of
+  hyperlinks to jump between methods. This makes it easier to understand the flow
+of control through a program and which methods take the most time.</p>
+<p>Below is the  output from running printers_test.rb reproduced in HTML. </p>

+
+== Overview
+Dashed lines divide the report into entries, with one entry
+per method.  Entries are sorted by total time which is the 
+time spent in the method plus its children. 
+
+Each entry has a primary line demarked by values in the 
+%total and %self columns.  The primary line represents 
+the method being profiled.  Lines above it are the methods
+that called this method (parents) while the lines below it
+are the methods it called (children).
+
+All values are in seconds.  For the primary line, the columns represent:
+
+	%total       - The percentage of time spent in this method and its children
+	%self        - The percentage of time spent in this method
+	total        - The time spent in this method and its children.
+	self         - The time spent in this method.
+	children     - The time spent in this method's children.
+	calls        - The number of times this method was called.
+	name         - The name of the method.
+  
+The interpretation of method names is:
+* #toplevel - The root method that calls all other methods
+* MyObject#test - An instance method "test" of the class "MyObject"
+* <Object:MyObject>#test - The <> characters indicate a singleton method on a singleton class.
+
+For example, we see that 99.48% of the time was spent in Integer#upto and its children.
+Of that time, 4.06 seconds was spent in Integer#upto itself and 4.66 in its children.
+Overall, Integer#upto was called 501 times.
+
+== Parents
+In each entry, the lines above the primary line are the methods that 
+called the current method.  If the current method is a root method then
+no parents are shown.
+
+
+For parent lines, the columns represent:
+
+	total        - The time spent in the current method and it children on behalf of the parent method.
+	self         - The time spent in this method on behalf of the parent method.
+	children     - The time spent in this method's children on behalf of the parent.
+	calls        - The number of times the parent method called this child
+  
+Looking at Integer#upto again, we see that it was called 500 times from Object#is_prime
+and 1 time from find_largest.  Of the 8.72 total seconds spent in Integer#upto, 6.63
+were done for Object#is_prime and 2.09 for Object#find_largest.
+
+
+== Children
+In each entry, the lines below the primary line are the methods that 
+the current method called.  If the current method is a leaf method then
+no children are shown.
+
+For children lines, the columns represent:
+
+	total        - The time spent in the child, and its children, on behalf of the current method
+	self         - The time spent in the child on behalf of the current method.
+	children     - The time spent in the child's children (ie, granchildren) in behalf of the current method
+	calls        - The number of times the child method was called by the current method.
+
+Taking our example of Integer#upto, we see that it called five other methods - Array#[],
+Fixnum#>, Kernel.sleep, Fixnum#= and Fixnum#%.  Looking at Kernel.sleep, we see that 
+its spent 2.09 seconds working for Integer#upto and its children spent 0 time working for
+Integer#upto.  To see the overall time Kernel.sleep took we would have to look up its entry
+in the graph table.

+/* ruby-prof tracks the time spent executing every method in ruby programming.
+   The main players are:
+
+     profile_t         - This represents 1 profile.
+     thread_data_t     - Stores data about a single thread.
+     prof_stack_t      - The method call stack in a particular thread
+     prof_method_t     - Profiling information about each method
+     prof_call_info_t  - Keeps track a method's callers and callees.
+
+  The final result is an instance of a profile object which has a hash table of
+  thread_data_t, keyed on the thread id.  Each thread in turn has a hash table
+  of prof_method_t, keyed on the method id.  A hash table is used for quick

+  Each prof_method_t has two hash tables, parent and children, of prof_call_info_t.
+  These objects keep track of a method's callers (who called the method) and its
+  callees (who the method called).  These are keyed the method id, but once again,
+  are exposed to Ruby as arrays.  Each prof_call_into_t maintains a pointer to the

+  #
+  # All of the options provided by
+  # the Rake:TestTask are supported except the loader
+  # which is set to ruby-prof.  For detailed information
+  # please refer to the Rake:TestTask documentation.
+  #
+  # ruby-prof specific options include:
+  #
+  #   output_dir - For each file specified an output
+  #                file with profile information will be
+  #                written to the output directory.
+  #                By default, the output directory is
+  #                called "profile" and is created underneath
+  #                the current working directory.
+  #
+  #   printer - Specifies the output printer.  Valid values include
+  #             :flat, :graph, :graph_html and :call_tree.
+  #
+  #   min_percent - Methods that take less than the specified percent
+  #                 will not be written out.
+  #
+  # Example:
+  #
+  #   require 'ruby-prof/task'
+  #
+  #   RubyProf::ProfileTask.new do |t|
+  #     t.test_files = FileList['test/test*.rb']

+  #     t.min_percent = 10
+  #   end
+  #
+  # If rake is invoked with a "TEST=filename" command line option,
+  # then the list of test files will be overridden to include only the
+  # filename specified on the command line.  This provides an easy way
+  # to run just one test.
+  #
+  # If rake is invoked with a "TESTOPTS=options" command line option,
+  # then the given options are passed to the test process after a
+  # '--'.  This allows Test::Unit options to be passed to the test
+  # suite.
+  #
+  # Examples:
+  #
+  #   rake profile                           # run tests normally
+  #   rake profile TEST=just_one_file.rb     # run just one test file.

+ruby-prof is a fast code profiler for Ruby. It is a C extension and
+therefore is many times faster than the standard Ruby profiler. It
+supports both flat and graph profiles.  For each method, graph profiles
+show how long the method ran, which methods called it and which
+methods it called. RubyProf generate both text and html and can output
+it to standard out or to a file.

+
+    *Vicent Martí*
+
+## Rugged 0.23.1 (August 11, 2015) ##
+
+*   Update bundled libgit2 to 98f7bd289dfb172473b7d7353d4b0f0b09c67937.
+
+    *Vicent Martí*
+
+## Rugged 0.23.0 (July 6, 2015) ##
+
+*   Update bundled libgit2 to 0.23.0.
+
+    See https://github.com/libgit2/libgit2/releases/tag/v0.23.0
+    for a list of fixed issues and new features.
+
+    *Arthur Schreiber*
+
+*   Add `Rugged::Repository#checkout_index`.
+
+    This allows to perform checkout from a given index.
+    It might be handy in case of manual merge conflicts resolution with user intervention.
+
+    *Dmytro Milinevskyy*
+
+*   Remove `Rugged::Submodule#reset_update_rule`, `Rugged::Submodule#reset_ignore_rule`
+    and `Rugged::Submodule#save`.
+
+    These methods were removed due to changes in the underlying libgit2 API.
+
+    *Arthur Schreiber*
+
+*   Add `Rugged::Blob#loc`.
+
+    Returns the number of lines in a blob, assuming it is plaintext.
+
+    *Vicent Martí*
+
+*   Add `Rugged::Walker.walk`.
+
+    This API allows creating a walker, performing a walk, and cleaning it up
+    immediately after the walk was performed.
+
+    *Vicent Martí*
+
+*   Add accessors for the Repository ident.
+
+    Added `Repository#ident` and `Repository#ident=` to read and set the
+    identity that is used when writing reflog entries.
+
+    *Arthur Schreiber*
+
+*   `Rugged::Remote` instances are now immutable.
+
+    * `Remote#clear_refspecs` and `Remote#save` were removed without
+      replacement.
+
+    * `Remote#url=` and `Remote#push_url=` were removed and replaced by
+      `RemoteCollection#set_url` and `RemoteCollection#set_push_url`.
+
+    * `Remote#add_push` and `Remote#add_fetch` were removed and replaced by
+      `RemoteCollection#add_push_refspec` and
+      `RemoteCollection#add_fetch_refspec`.
+
+    *Arthur Schreiber*
+
+*   Update bundled libgit2 to 9042693e283f65d9afb4906ed693a862a250664b.
+
+    *Arthur Schreiber*
+
+*   Updated the API of reflog modifying methods.
+
+    This removes both the optional `:message` as well as `:signature` options from
+    the following methods:
+
+    * `BranchCollection#create`, `BranchCollection#move`, `BranchCollection#rename`
+    * `ReferenceCollection#create`, `ReferenceCollection#rename`
+    * `Remote#push`
+    * `Repository#reset`
+
+    Additionally, the `:signature` option from `Remote#fetch` was removed as well.
+
+    The reflog message is now automatically generated and committed with the
+    the identity that is set in the Repository's configuration.
+
+    *Arthur Schreiber*
+
+*   The `:safe_create` flag was removed from `Repository#checkout_tree`.
+
+    You can use `:create` in combination with `:recreate_missing` instead.
+
+    *Arthur Schreiber*
+
+
+## Rugged 0.22.2 (May 17, 2015) ##
+
+*   Update bundled libgit2 to 0.22.2.
+
+    See https://github.com/libgit2/libgit2/releases/tag/v0.22.0,
+    https://github.com/libgit2/libgit2/releases/tag/v0.22.1 and
+    https://github.com/libgit2/libgit2/releases/tag/v0.22.2 for a list
+    of fixed issues and new features.
+
+    *Arthur Schreiber*
+
+*   Add `Rugged::Tree#count_recursive`.
+
+    This counts all blobs in a tree, recursively, with an optional limit
+    to bail early. This allows asking things like: "Are there more
+    than 1 million files in this repo?" in a very performant way.
+
+    Fixes #464.
+
+    *Andy Delcambre*
+
+*   Add missing handling of libgit2 errors in `Rugged::BranchCollection#each`
+    and `Rugged::BranchCollection#each_name`.
+
+    Fixes #457.
+
+    *aiionx*
+
+*   The `Rugged::Tree::Builder` API was changed to account for libgit2 changes.
+
+    When creating a new `Rugged::Tree::Builder` instance through
+    `Rugged::Tree::Builder.new` you have to pass a repository instance,
+    while `Rugged::Tree::Builder#write` does not take any arguments anymore.
+
+    *Vicent Martí*
+
+*   Add alternative backend support (experimental).
+
+    Bare repositories can now be stored using an alternative backend.
+
+    Fixes #410.
+
+    *Viktor Charypar*
+
+*   Replace `Remote#rename!` with `RemoteCollection#rename`.
+
+    This brings the `RemoteCollection` more in line with the API of
+    `ReferenceCollection` and `BranchCollection`.
+
+    *Arthur Schreiber*
+
+*   Remove URL validation from `Remote#url=`, `Remote#push_url=`,
+    `RemoteCollection#create_anonymous` and `RemoteCollection#create`,
+    as the underlying function `git_remote_supported_url()` was removed
+    from libgit2.
+
+    *Arthur Schreiber*
+
+*   Add `Repository#merge_bases`.
+
+    This returns an array containing all merge bases between one or
+    multiple commits.
+
+    *Arthur Schreiber*
+
+*   Add submodule support.
+
+    Expose git submodules functionality through `Rugged::Submodule` and
+    `Rugged::SubmoduleCollection`.
+
+    *Nikolai Vladimirov*
+
+*   Add `Rugged::Walker#push_range`.
+
+    *Evgeniy Sokovikov*
+
+*   Implement `Rugged::Blob::HashSignature` and `Rugged::Blob#hashsig`.
+
+    Allows similarity detection of `Rugged::Blob` instances against other blobs or
+    arbitrary strings.
+
+    *Vicent Martí*
+
+*   Add `Rugged::Repository#attributes`.
+
+    This method allows accessing the attributes for different path names as
+    specified by `.gitattributes` files.
+
+    *Vicent Martí*
+
+*   Add `Rugged::TagCollection#create_annotation`.
+
+    This method allows the creation of a tag object, but without creating
+    a tag reference.
+
+    *Charlie Somerville*
+
+*   Add `Rugged::Repository#cherrypick`.
+
+    *Arthur Schreiber*
+
+*   Add `Rugged::Repository#descendant_of?`
+
+    *Jake Douglas*
+
+*   `Rugged::Index#read_tree` now actually checks that the given object is a
+    `Rugged::Tree` instance.
+
+    Fixes #401.
+
+    *Andy Delcambre*
+
+*   Add `Rugged::Repository#expand_oids`.
+
+    This allows expanding a list of shortened SHA1 strings, optionally restricting
+    the expansion to a specific object type.
+
+    *Vicent Martí*
+
+*   Add `Rugged::Remote#check_connection`.
+
+    This is useful if one needs to check if it is possible to fetch/push
+    from/to the remote.
+
+    Basically, it is analogue to `git fetch --dry-run` and `git push --dry-run`.
+
+    *Dmitry Medvinsky*
+
+*   Remove defunct `Rugged::Diff::Line#hunk` and `Rugged::Diff::Line#owner`.
+
+    Fixes #390.
+
+    *Arthur Schreiber*
+
+*   Remove `Rugged::Diff#tree` and change `Rugged::Diff#owner` to return the
+    repository that the `Rugged::Diff` object belongs to.
+
+    We need to keep a reference from the `Rugged::Diff` to the repository to
+    ensure that the underlying libgit2 data does not get freed accidentally.
+
+    Fixes #389.
+
+    *Arthur Schreiber*
+
+*   Add `#additions` and `#deletions` to `Rugged::Patch`.
+
+    *Mindaugas Mozūras*
+
+
+## Rugged 0.21.4 (January 18, 2015) ##

+# Rugged
+**libgit2 bindings in Ruby**
+
+Rugged is a library for accessing [libgit2](https://github.com/libgit2/libgit2) in Ruby. It gives you the speed and
+portability of libgit2 with the beauty of the Ruby language.
+
+### libgit2
+
+libgit2 is a pure C implementation of the Git core methods. It's designed to be
+fast and portable. For more information about libgit2,
+[check out libgit2's website](http://libgit2.github.com) or browse the
+[libgit2 organization](https://github.com/libgit2) on GitHub.
+
+## Install
+
+Rugged is a self-contained gem. You can install it by running:
+
+    $ gem install rugged
+
+You need to have CMake and `pkg-config` installed on your system to be able to build the included version of `libgit2`. On OS X, after installing [Homebrew](http://brew.sh/), you can get CMake with:
+```bash
+$ brew install cmake
+```
+
+If you want to build Rugged with HTTPS and SSH support, check out the list of optional [libgit2 dependencies](https://github.com/libgit2/libgit2#optional-dependencies).
+
+If you're using bundler and want to bundle `libgit2` with Rugged, you can use the `:submodules` option:
+
+```ruby
+gem 'rugged', git: 'git://github.com/libgit2/rugged.git', submodules: true
+```
+
+To load Rugged, you'll usually want to add something like this:
+
+```ruby
+require 'rugged'
+```
+
+### Use the system provided libgit2
+
+By default, Rugged builds and uses a bundled version of libgit2. If you
+want to use the system library instead, you can install rugged as follows:
+
+```
+gem install rugged -- --use-system-libraries
+```
+
+Or if you are using bundler:
+
+```
+bundle config build.rugged --use-system-libraries
+bundle install
+```
+
+However, note that Rugged does only support specific versions of libgit2.
+
+## Usage
+
+Rugged gives you access to the many parts of a Git repository. You can read and
+write objects, walk a tree, access the staging area, and lots more. Let's look
+at each area individually.
+
+### Repositories
+
+#### Instantiation
+
+The repository is naturally central to Git. Rugged has a `Repository` class that
+you can instantiate with a path to open an existing repository :
+
+```ruby
+repo = Rugged::Repository.new('path/to/my/repository')
+# => #<Rugged::Repository:2228536260 {path: "path/to/my/repository/.git/"}>
+```
+
+You can create a new repository with `init_at`. Add a second parameter `:bare` to make a bare repository:
+
+```ruby
+Rugged::Repository.init_at('.', :bare)
+```
+
+You can also let Rugged discover the path to the .git directory if you give it a
+subdirectory.
+
+```ruby
+Rugged::Repository.discover("/Users/me/projects/repo/lib/subdir/")
+# => "/Users/me/projects/repo/.git/"
+```
+
+Once your Repository instantiated (in the following examples, as `repo`), you
+can access or modify it.
+
+#### Accessing a Repository
+
+```ruby
+# Does the given SHA1 exist in this repository?
+repo.exists?('07b44cbda23b726e5d54e2ef383495922c024202')
+# => true
+
+# Boolean repository state values:
+repo.bare?
+# => false
+repo.empty?
+# => true
+repo.head_unborn?
+# => false
+repo.head_detached?
+# => false
+
+# Path accessors
+repo.path
+# => "path/to/my/repository/.git/"
+repo.workdir
+# => "path/to/my/repository/"
+
+# The HEAD of the repository.
+ref = repo.head
+# => #<Rugged::Reference:2228467240 {name: "refs/heads/master", target:  #<Rugged::Commit:2228467250 {message: "helpful message", tree: #<Rugged::Tree:2228467260 {oid: 5d6f29220a0783b8085134df14ec4d960b6c3bf2}>}>
+
+# From the returned ref, you can also access the `name`, `target`, and target SHA:
+ref.name
+# => "refs/heads/master"
+ref.target
+# => #<Rugged::Commit:2228467250 {message: "helpful message", tree: #<Rugged::Tree:2228467260 {oid: 5d6f29220a0783b8085134df14ec4d960b6c3bf2}>}>
+ref.target_id
+# => "2bc6a70483369f33f641ca44873497f13a15cde5"
+
+# Reading an object
+object = repo.read('a0ae5566e3c8a3bddffab21022056f0b5e03ef07')
+# => #<Rugged::OdbObject:0x109a64780>
+object.len
+# => 237
+object.data
+# => "tree 76f23f186076fc291742816721ea8c3e95567241\nparent 8e3c5c52b8f29da0adc7e8be8a037cbeaea6de6b\nauthor Vicent Mart\303\255 <tanoku at gmail.com> 1333859005 +0200\ncommitter Vicent Mart\303\255 <tanoku at gmail.com> 1333859005 +0200\n\nAdd `Repository#blob_at`\n"
+object.type
+# => :commit
+```
+
+#### Writing to a Repository
+
+There's a few ways to write to a repository. To write directly from your
+instantiated repository object:
+
+```ruby
+sha = repo.write(content, type)
+```
+
+You can also use the `Commit` object directly to craft a commit; this is a bit
+more high-level, so it may be preferable:
+
+```ruby
+oid = repo.write("This is a blob.", :blob)
+index = repo.index
+index.read_tree(repo.head.target.tree)
+index.add(:path => "README.md", :oid => oid, :mode => 0100644)
+
+options = {}
+options[:tree] = index.write_tree(repo)
+
+options[:author] = { :email => "testuser at github.com", :name => 'Test Author', :time => Time.now }
+options[:committer] = { :email => "testuser at github.com", :name => 'Test Author', :time => Time.now }
+options[:message] ||= "Making a commit via Rugged!"
+options[:parents] = repo.empty? ? [] : [ repo.head.target ].compact
+options[:update_ref] = 'HEAD'
+
+Rugged::Commit.create(repo, options)
+```
+
+---
+
+### Objects
+
+`Object` is the main object class - it shouldn't be created directly, but all of
+these methods should be useful in their derived classes.
+
+```ruby
+obj = repo.lookup(sha)
+obj.oid  # object sha
+obj.type # One of :commit, :tree, :blob or :tag
+
+robj = obj.read_raw
+str  = robj.data
+int  = robj.len
+```
+
+There are four base object types in Git: **blobs**, **commits**, **tags**, and
+**trees**. Each of these object types have a corresponding class within Rugged.
+
+### Commit Objects
+
+```ruby
+commit = repo.lookup('a0ae5566e3c8a3bddffab21022056f0b5e03ef07')
+# => #<Rugged::Commit:2245304380>
+
+commit.message
+# => "Add `Repository#blob_at`\n"
+
+commit.time
+# => Sat Apr 07 21:23:25 -0700 2012
+
+commit.author
+# => {:email=>"tanoku at gmail.com", :name=>"Vicent Mart\303\255", :time=>Sun Apr 08 04:23:25 UTC 2012}
+
+commit.tree
+# => #<Rugged::Tree:2245269740>
+
+commit.parents
+# => [#<Rugged::Commit:2245264600 {message: "Merge pull request #47 from isaac/remotes\n\nAdd Rugged::Repository#remotes", tree: #<Rugged::Tree:2245264240 {oid: 6a2aee58a41fa007d07aa55565e2231f9b39b4a9}>]
+```
+
+You can also write new objects to the database this way:
+
+```ruby
+author = {:email=>"tanoku at gmail.com", :time=>Time.now, :name=>"Vicent Mart\303\255"}
+
+Rugged::Commit.create(r,
+	:author => author,
+	:message => "Hello world\n\n",
+	:committer => author,
+	:parents => ["2cb831a8aea28b2c1b9c63385585b864e4d3bad1"],
+	:tree => some_tree,
+	:update_ref => "HEAD") #=> "f148106ca58764adc93ad4e2d6b1d168422b9796"
+```
+
+### Tag Objects
+
+```ruby
+tag  = repo.lookup(tag_sha)
+
+object = tag.target
+sha    = tag.target.oid
+str    = tag.target_type # :commit, :tag, :blob
+str    = tag.name        # "v1.0"
+str    = tag.message
+person = tag.tagger
+```
+
+### Tree Objects
+
+```ruby
+tree = repo.lookup('779fbb1e17e666832773a9825875300ea736c2da')
+# => #<Rugged::Tree:2245194360>
+
+# number of tree entries
+tree.count
+
+tree[0]           # or...
+tree.first        # or...
+tree.get_entry(0)
+# => {:type=>:blob, :oid=>"99e7edb53db9355f10c6f2dfaa5a183f205d93bf", :filemode=>33188, :name=>".gitignore"}
+```
+
+The tree object is an Enumerable, so you can also do stuff like this:
+
+```ruby
+tree.each { |e| puts e[:oid] }
+tree.sort { |a, b| a[:oid] <=> b[:oid] }.map { |e| e[:name] }.join(':')
+```
+
+And there are some Rugged-specific methods, too:
+
+```ruby
+tree.each_tree { |entry| puts entry[:name] }  # list subdirs
+tree.each_blob { |entry| puts entry[:name] }  # list only files
+```
+
+You can also write trees with the `TreeBuilder`:
+
+```ruby
+oid = repo.write("This is a blob.", :blob)
+builder = Rugged::Tree::Builder.new(repo)
+builder << { :type => :blob, :name => "README.md", :oid => oid, :filemode => 0100644 }
+
+options = {}
+options[:tree] = builder.write
+
+options[:author] = { :email => "testuser at github.com", :name => 'Test Author', :time => Time.now }
+options[:committer] = { :email => "testuser at github.com", :name => 'Test Author', :time => Time.now }
+options[:message] ||= "Making a commit via Rugged!"
+options[:parents] = repo.empty? ? [] : [ repo.head.target ].compact
+options[:update_ref] = 'HEAD'
+
+Rugged::Commit.create(repo, options)
+```
+
+### Blob Objects
+
+Blob objects represent the data in the files of a Tree Object.
+
+```ruby
+blob = repo.lookup('e1253910439ea902cf49be8a9f02f3c08d89ac73')
+blob.content # => Gives you the content of the blob.
+```
+
+#### Streaming Blob Objects
+
+There is currently no way to stream data from a blob, because `libgit2` itself does not (yet) support
+streaming blobs out of the git object database. While there are hooks and interfaces for supporting it,
+the default file system backend always loads the entire blob contents into memory. 
+
+If you need to access a Blob object through an IO-like API, you can wrap it with the `StringIO` class.
+Note that the only advantage here is a stream-compatible interface, the complete blob object will still
+be loaded into memory. Below is an example for streaming a Blob using the Sinatra framework:
+
+```ruby
+# Sinatra endpoint
+get "/blobs/:sha" do
+  repo = Rugged::Repository.new(my_repo_path)
+  blob = repo.lookup params[:sha]
+
+  headers({
+    "Vary" => "Accept",
+    "Connection" => "keep-alive",
+    "Transfer-Encoding" => "chunked",
+    "Content-Type" => "application/octet-stream",
+  })
+
+  stream do |out|
+    StringIO.new(blob.content).each(8000) do |chunk|
+      out << chunk
+    end
+  end
+end
+```
+
+---
+
+### Commit Walker
+
+`Rugged::Walker` is a class designed to help you traverse a set of commits over
+a repository.
+
+You first push head SHAs onto the walker, and then call next to get a list of
+the reachable commit objects one at a time. You can also `hide()` commits if you
+are not interested in anything beneath them (useful in situations like when
+you're running something like `git log master ^origin/master`).
+
+```ruby
+walker = Rugged::Walker.new(repo)
+walker.sorting(Rugged::SORT_TOPO | Rugged::SORT_REVERSE) # optional
+walker.push(hex_sha_interesting)
+walker.hide(hex_sha_uninteresting)
+walker.each { |c| puts c.inspect }
+walker.reset
+```
+
+---
+
+### Index ("staging") area
+
+We can inspect and manipulate the Git Index as well. To work with the index
+inside an existing repository, instantiate it by using the `Repository.index`
+method instead of manually opening the Index by its path.
+
+```ruby
+index = Rugged::Index.new(path)
+
+# Re-read the index file from disk.
+index.reload
+
+# Count up index entries.
+count = index.count
+
+# The collection of index entries.
+index.entries
+
+# Iterating over index entries.
+index.each { |i| puts i.inspect }
+
+# Get a particular entry in the index.
+index[path]
+
+# Unstage.
+index.remove(path)
+
+# Stage. Also updates existing entry if there is one.
+index.add(ientry)
+
+# Stage. Create ientry from file in path, updates the index.
+index.add(path)
+```
+
+---
+
+### Refs
+
+You can access references through the `Rugged::ReferenceCollection` object returned by `Repository#references`.
+
+```ruby
+ref = repo.references["refs/heads/master"]
+
+sha = ref.target_id
+str = ref.type   # :direct
+str = ref.name   # "refs/heads/master"
+```
+
+You can also easily iterate over all references:
+
+```ruby
+repo.references.each do |ref|
+  puts ref.name
+end
+```
+
+Or only over references that match the given pattern (glob):
+
+```ruby
+repo.references.each("refs/tags/*") do |ref|
+  puts ref.name
+end
+```
+
+It is also easy to create, update, rename or delete a reference:
+
+```ruby
+ref = repo.references.create("refs/heads/unit_test", some_commit_sha)
+
+repo.references.update(ref, new_sha) # or...
+repo.references.update("refs/heads/unit_test", new_sha)
+
+repo.references.rename(ref, "refs/heads/blead") # or...
+repo.references.rename("refs/heads/unit_test", "refs/heads/blead")
+
+repo.references.delete(ref) # or...
+repo.references.delete("refs/heads/unit_test") # or...
+```
+
+Finally, you can access the reflog for any branch:
+
+```ruby
+ref = repo.references["refs/heads/master"]
+entry = ref.log.first
+sha   = entry[:id_old]
+sha   = entry[:id_new]
+str   = entry[:message]
+prsn  = entry[:committer]
+```
+
+---
+
+### Branches
+
+The `Rugged::BranchCollection` object returned by `Repository#branches` will help
+you with all of your branch-related needs.
+
+Iterate over all branches:
+
+```ruby
+repo.branches.each_name().sort
+# => ["master", "origin/HEAD", "origin/master", "origin/packed"]
+
+repo.branches.each_name(:local).sort
+# => ["master"]
+
+repo.branches.each_name(:remote).sort
+# => ["origin/HEAD", "origin/master", "origin/packed"]
+```
+
+Look up branches and get attributes:
+
+```ruby
+branch = repo.branches["master"]
+branch.name # => 'master'
+branch.canonical_name # => 'refs/heads/master'
+```
+
+Look up the id for the target of a branch:
+
+```ruby
+repo.branches["master"].target_id
+# => "36060c58702ed4c2a40832c51758d5344201d89a"
+```
+
+Creation and deletion:
+
+```ruby
+branch = repo.branches.create("test_branch", "HEAD")
+
+repo.branches.rename("test_branch", "new_branch") # or...
+repo.branches.rename("refs/heads/test_branch", "new_branch") # or...
+repo.branches.rename(ref, "new_branch") # or...
+
+repo.branches.delete("test_branch") # or...
+repo.branches.delete("refs/heads/test_branch") # or...
+repo.branches.delete(ref) # or...
+```
+
+---
+
+### Diffs
+
+There are various ways to get hands on diffs:
+
+```ruby
+# Diff between two subsequent commits
+diff_commits = commit_object.parents[0].diff(commit_object)
+
+# Diff between two tree objects
+diff_trees = tree_object_a.diff(tree_object_b)
+
+# Diff between index/staging and current working directory
+diff_index = repository.index.diff
+
+# Diff between index/staging and another diffable (commit/tree/index)
+diff_index_diffable = repository.index.diff(some_diffable)
+```
+
+When you already have a diff object, you can examine it:
+
+```ruby
+# Get patch
+diff.patch
+=> "diff --git a/foo1 b/foo1\nnew file mode 100644\nindex 0000000..81b68f0\n--- /dev/null\n+++ b/foo1\n@@ -0,0 +1,2 @@\n+abc\n+add line1\ndiff --git a/txt1 b/txt1\ndeleted file mode 100644\nindex 81b68f0..0000000\n--- a/txt1\n+++ /dev/null\n@@ -1,2 +0,0 @@\n-abc\n-add line1\ndiff --git a/txt2 b/txt2\nindex a7bb42f..a357de7 100644\n--- a/txt2\n+++ b/txt2\n@@ -1,2 +1,3 @@\n abc2\n add line2-1\n+add line2-2\n"
+
+# Get delta (faster, if you only need information on what files changed)
+diff.each_delta{ |d| puts d.inspect }
+#<Rugged::Diff::Delta:70144372137380 {old_file: {:oid=>"0000000000000000000000000000000000000000", :path=>"foo1", :size=>0, :flags=>6, :mode=>0}, new_file: {:oid=>"81b68f040b120c9627518213f7fc317d1ed18e1c", :path=>"foo1", :size=>14, :flags=>6, :mode=>33188}, similarity: 0, status: :added>

+
+# Merge one diff into another (mutating the first one)
+diff1.merge!(diff2)
+
+# Write a patch into a file (or any other object responding to write)
+# Note that the patch as in diff.patch will be written, it won't be applied
+file = File.open('/some/file', 'w')
+diff.write_patch(file)
+file.close
+```
+
+---
+
+### Config files
+
+It's also easy to read and manipulate the Git config file data with Rugged.
+
+```ruby
+# Read values
+repo.config['core.bare']
+
+# Set values
+repo.config['user.name'] = true
+
+# Delete values
+repo.config.delete('user.name')
+```
+
+---
+
+### General methods
+
+Rugged also includes a general library for handling basic Git operations. One of
+these is converting a raw sha (20 bytes) into a readable hex sha (40
+characters).
+
+```ruby
+Rugged.hex_to_raw('bfde59cdd0dfac1d892814f66a95641abd8a1faf')
+# => "\277\336Y\315\320\337\254\035\211(\024\366j\225d\032\275\212\037\257"
+
+Rugged.raw_to_hex("\277\336Y\315\320\337\254\035\211(\024\366j\225d\032\275\212\037\257")
+=> "bfde59cdd0dfac1d892814f66a95641abd8a1faf"
+```
+
+---
+
+### Alternative backends
+
+You can store bare repositories in alternative backends instead of storing on disk. (see
+`redbadger/rugged-redis` for an example of how a rugged backend works).
+
+```ruby
+a_backend = Rugged::InMemory::Backend.new(opt1: 'setting', opt2: 'setting')
+
+repo = Rugged::Repository.init_at('repo_name', :bare, backend: a_backend)
+
+# or
+
+repo = Rugged::Repository.bare('repo_name', backend: a_backend)
+```

+ *
+ *  :patience ::

+ *
+ *  :include_ignored ::
+ *    If true, ignored files will be included in the diff.
+ *
+ *  :include_untracked ::
+ *   If true, untracked files will be included in the diff.
+ *
+ *  :include_unmodified ::
+ *    If true, unmodified files will be included in the diff.
+ *
+ *  :recurse_untracked_dirs ::
+ *    Even if +:include_untracked+ is true, untracked directories will only be
+ *    marked with a single entry in the diff. If this flag is set to true,
+ *    all files under ignored directories will be included in the diff, too.

+ *
+ *  :include_typechange ::

+ *
+ *  :include_typechange_trees ::

+ *
+ *    :update_only ::
+ *      Only update existing files, don't create new ones.
+ *
+ *    :dont_update_index ::
+ *      Normally checkout updates index entries as it goes; this stops that.
+ *
+ *    :no_refresh ::
+ *      Don't refresh index/config/etc before doing checkout.
+ *
+ *    :disable_pathspec_match ::
+ *      Treat pathspec as simple list of exact match file paths.
+ *
+ *    :skip_locked_directories ::

+ *  :file_open_flags ::
+ *    Mode for opening files. Default: <code>IO::CREAT | IO::TRUNC | IO::WRONLY</code>.
+ *
+ *  :notify_flags ::
+ *    A single symbol or an array of symbols representing the cases in which the +:notify+
+ *    callback should be invoked. Possible values are:
+ *
+ *    :none ::
+ *      Do not invoke the +:notify+ callback (default).
+ *
+ *    :conflict ::
+ *      Invoke the callback for conflicting paths.
+ *
+ *    :dirty ::
+ *      Invoke the callback for "dirty" files, i.e. those that do not need an update but

+ *  parent tree or the +diffable+ object will be used for the "new file" side.
+ *
+ *  If +tree+ or +diffable+ are nil, they will be treated as an empty tree. Passing
+ *  both as `nil` will raise an exception.
+ *
+ *  The following options can be passed in the +options+ Hash:
+ *
+ *  :paths ::
+ *    An array of paths / fnmatch patterns to constrain the diff to a specific
+ *    set of files. Also see +:disable_pathspec_match+.
+ *
+ *  :max_size ::
+ *    An integer specifying the maximum byte size of a file before a it will
+ *    be treated as binary. The default value is 512MB.
+ *
+ *  :context_lines ::
+ *    The number of unchanged lines that define the boundary of a hunk (and
+ *    to display before and after the actual changes). The default is 3.
+ *
+ *  :interhunk_lines ::
+ *    The maximum number of unchanged lines between hunk boundaries before the hunks
+ *    will be merged into a one. The default is 0.
+ *
+ *  :old_prefix ::
+ *    The virtual "directory" to prefix to old filenames in hunk headers.
+ *    The default is "a".
+ *
+ *  :new_prefix ::
+ *    The virtual "directory" to prefix to new filenames in hunk headers.
+ *    The default is "b".
+ *
+ *  :reverse ::
+ *    If true, the sides of the diff will be reversed.
+ *
+ *  :force_text ::
+ *    If true, all files will be treated as text, disabling binary attributes & detection.
+ *
+ *  :ignore_whitespace ::
+ *    If true, all whitespace will be ignored.
+ *
+ *  :ignore_whitespace_change ::
+ *    If true, changes in amount of whitespace will be ignored.
+ *
+ *  :ignore_whitespace_eol ::
+ *    If true, whitespace at end of line will be ignored.
+ *
+ *  :ignore_submodules ::
+ *    if true, submodules will be excluded from the diff completely.
+ *
+ *  :patience ::
+ *    If true, the "patience diff" algorithm will be used (currenlty unimplemented).
+ *
+ *  :include_ignored ::
+ *    If true, ignored files will be included in the diff.
+ *
+ *  :include_untracked ::
+ *   If true, untracked files will be included in the diff.
+ *
+ *  :include_unmodified ::
+ *    If true, unmodified files will be included in the diff.
+ *
+ *  :recurse_untracked_dirs ::
+ *    Even if +:include_untracked+ is true, untracked directories will only be
+ *    marked with a single entry in the diff. If this flag is set to true,
+ *    all files under ignored directories will be included in the diff, too.
+ *
+ *  :disable_pathspec_match ::
+ *    If true, the given +:paths+ will be applied as exact matches, instead of
+ *    as fnmatch patterns.
+ *
+ *  :deltas_are_icase ::
+ *    If true, filename comparisons will be made with case-insensitivity.
+ *
+ *  :include_untracked_content ::
+ *    if true, untracked content will be contained in the the diff patch text.
+ *
+ *  :skip_binary_check ::
+ *    If true, diff deltas will be generated without spending time on binary
+ *    detection. This is useful to improve performance in cases where the actual
+ *    file content difference is not needed.
+ *
+ *  :include_typechange ::
+ *    If true, type changes for files will not be interpreted as deletion of
+ *    the "old file" and addition of the "new file", but will generate
+ *    typechange records.
+ *
+ *  :include_typechange_trees ::
+ *    Even if +:include_typechange+ is true, blob -> tree changes will still
+ *    usually be handled as a deletion of the blob. If this flag is set to true,
+ *    blob -> tree changes will be marked as typechanges.
+ *
+ *  :ignore_filemode ::
+ *    If true, file mode changes will be ignored.
+ *
+ *  :recurse_ignored_dirs ::
+ *    Even if +:include_ignored+ is true, ignored directories will only be
+ *    marked with a single entry in the diff. If this flag is set to true,
+ *    all files under ignored directories will be included in the diff, too.
+ *
+ *  Examples:
+ *
+ *    # Emulating `git diff <treeish>`
+ *    tree = Rugged::Tree.lookup(repo, "d70d245ed97ed2aa596dd1af6536e4bfdb047b69")
+ *    diff = tree.diff(repo.index)
+ *    diff.merge!(tree.diff)
+ *
+ *    # Tree-to-Tree Diff
+ *    tree = Rugged::Tree.lookup(repo, "d70d245ed97ed2aa596dd1af6536e4bfdb047b69")
+ *    other_tree = Rugged::Tree.lookup(repo, "7a9e0b02e63179929fed24f0a3e0f19168114d10")

+# Rugged
+**libgit2 bindings in Ruby**
+
+Rugged is a library for accessing [libgit2](https://github.com/libgit2/libgit2) in Ruby. It gives you the speed and
+portability of libgit2 with the beauty of the Ruby language.
+
+### libgit2
+
+libgit2 is a pure C implementation of the Git core methods. It's designed to be
+fast and portable. For more information about libgit2,
+[check out libgit2's website](http://libgit2.github.com) or browse the
+[libgit2 organization](https://github.com/libgit2) on GitHub.
+
+## Install
+
+Rugged is a self-contained gem. You can install it by running:
+
+    $ gem install rugged
+
+To load Rugged, you'll usually want to add something like this:
+
+```ruby
+require 'rugged'
+```
+
+## Usage
+
+Rugged gives you access to the many parts of a Git repository. You can read and
+write objects, walk a tree, access the staging area, and lots more. Let's look
+at each area individually.
+
+### Repositories
+
+#### Instantiation
+
+The repository is naturally central to Git. Rugged has a `Repository` class that
+you can instantiate with a path to open an existing repository :
+
+```ruby
+repo = Rugged::Repository.new('path/to/my/repository')
+# => #<Rugged::Repository:2228536260 {path: "path/to/my/repository/.git/"}>
+```
+
+You can create a new repository with `init_at`. Add a second parameter `:bare` to make a bare repository:
+
+```ruby
+Rugged::Repository.init_at('.', :bare)
+```
+
+You can also let Rugged discover the path to the .git directory if you give it a
+subdirectory.
+
+```ruby
+Rugged::Repository.discover("/Users/me/projects/repo/lib/subdir/")
+# => "/Users/me/projects/repo/.git/"
+```
+
+Once your Repository instantiated (in the following examples, as `repo`), you
+can access or modify it.
+
+#### Accessing a Repository
+
+```ruby
+# Does the given SHA1 exist in this repository?
+repo.exists?('07b44cbda23b726e5d54e2ef383495922c024202')
+# => true
+
+# Boolean repository state values:
+repo.bare?
+# => false
+repo.empty?
+# => true
+repo.head_orphan?
+# => false
+repo.head_detached?
+# => false
+
+# Path accessors
+repo.path
+# => "path/to/my/repository/.git/"
+repo.workdir
+# => "path/to/my/repository/"
+
+# The HEAD of the repository.
+ref = repo.head
+# => #<Rugged::Reference:2228467240 {name: "refs/heads/master", target: "07b44cbda23b726e5d54e2ef383495922c024202"}>
+
+# From the returned ref, you can also access the `name` and `target`:
+ref.name
+# => "refs/heads/master"
+ref.target
+# => "07b44cbda23b726e5d54e2ef383495922c024202"
+
+# Reading an object
+object = repo.read('a0ae5566e3c8a3bddffab21022056f0b5e03ef07')
+# => #<Rugged::OdbObject:0x109a64780>
+object.len
+# => 237
+object.data
+# => "tree 76f23f186076fc291742816721ea8c3e95567241\nparent 8e3c5c52b8f29da0adc7e8be8a037cbeaea6de6b\nauthor Vicent Mart\303\255 <tanoku at gmail.com> 1333859005 +0200\ncommitter Vicent Mart\303\255 <tanoku at gmail.com> 1333859005 +0200\n\nAdd `Repository#blob_at`\n"
+object.type
+# => :commit
+```
+
+#### Writing to a Repository
+
+There's a few ways to write to a repository. To write directly from your
+instantiated repository object:
+
+```ruby
+sha = repo.write(content, type)
+```
+
+You can also use the `Commit` object directly to craft a commit; this is a bit
+more high-level, so it may be preferable:
+
+```ruby
+oid = repo.write("This is a blob.", :blob)
+index = Rugged::Index.new
+index.add(:path => "README.md", :oid => oid, :mode => 0100644)
+
+options = {}
+options[:tree] = index.write_tree(repo)
+
+options[:author] = { :email => "testuser at github.com", :name => 'Test Author', :time => Time.now }
+options[:committer] = { :email => "testuser at github.com", :name => 'Test Author', :time => Time.now }
+options[:message] ||= "Making a commit via Rugged!"
+options[:parents] = repo.empty? ? [] : [ repo.head.target ].compact
+options[:update_ref] = 'HEAD'
+
+Rugged::Commit.create(repo, options)
+```
+
+---
+
+### Objects
+
+`Object` is the main object class - it shouldn't be created directly, but all of
+these methods should be useful in their derived classes.
+
+```ruby
+obj = repo.lookup(sha)
+obj.oid  # object sha
+obj.type # One of :commit, :tree, :blob or :tag
+
+robj = obj.read_raw
+str  = robj.data
+int  = robj.len
+```
+
+There are four base object types in Git: **blobs**, **commits**, **tags**, and
+**trees**. Each of these object types have a corresponding class within Rugged.
+
+### Commit Objects
+
+```ruby
+commit = repo.lookup('a0ae5566e3c8a3bddffab21022056f0b5e03ef07')
+# => #<Rugged::Commit:2245304380>
+
+commit.message
+# => "Add `Repository#blob_at`\n"
+
+commit.time
+# => Sat Apr 07 21:23:25 -0700 2012
+
+commit.author
+# => {:email=>"tanoku at gmail.com", :name=>"Vicent Mart\303\255", :time=>Sun Apr 08 04:23:25 UTC 2012}
+
+commit.tree
+# => #<Rugged::Tree:2245269740>
+
+commit.parents
+=> [#<Rugged::Commit:2245264600 {message: "Merge pull request #47 from isaac/remotes\n\nAdd Rugged::Repository#remotes", tree: #<Rugged::Tree:2245264240 {oid: 6a2aee58a41fa007d07aa55565e2231f9b39b4a9}>
+```
+
+You can also write new objects to the database this way:
+
+```ruby
+author = {:email=>"tanoku at gmail.com", :time=>Time.now, :name=>"Vicent Mart\303\255"}
+
+Rugged::Commit.create(r,
+	:author => author,
+	:message => "Hello world\n\n",
+	:committer => author,
+	:parents => ["2cb831a8aea28b2c1b9c63385585b864e4d3bad1"],
+	:tree => some_tree,
+	:update_ref => "HEAD") #=> "f148106ca58764adc93ad4e2d6b1d168422b9796"
+```
+
+### Tag Objects
+
+```ruby
+tag  = repo.lookup(tag_sha)
+
+object = tag.target
+sha    = tag.target.oid
+str    = tag.target_type # :commit, :tag, :blob
+str    = tag.name        # "v1.0"
+str    = tag.message
+person = tag.tagger
+```
+
+### Tree Objects
+
+```ruby
+tree = repo.lookup('779fbb1e17e666832773a9825875300ea736c2da')
+# => #<Rugged::Tree:2245194360>
+
+# number of tree entries
+tree.count
+
+tree[0]           # or...
+tree.first        # or...
+tree.get_entry(0)
+# => {:type=>:blob, :oid=>"99e7edb53db9355f10c6f2dfaa5a183f205d93bf", :filemode=>33188, :name=>".gitignore"}
+```
+
+The tree object is an Enumerable, so you can also do stuff like this:
+
+```ruby
+tree.each { |e| puts e[:oid] }
+tree.sort { |a, b| a[:oid] <=> b[:oid] }.map { |e| e[:name] }.join(':')
+```
+
+And there are some Rugged-specific methods, too:
+
+```ruby
+tree.each_tree { |entry| puts entry[:name] }  # list subdirs
+tree.each_blob { |entry| puts entry[:name] }  # list only files
+```
+
+You can also write trees with the `TreeBuilder`:
+
+```ruby
+oid = repo.write("This is a blob.", :blob)
+builder = Rugged::Tree::Builder.new
+builder << { :type => :blob, :name => "README.md", :oid => oid, :filemode => 0100644 }
+
+options = {}
+options[:tree] = builder.write(repo)
+
+options[:author] = { :email => "testuser at github.com", :name => 'Test Author', :time => Time.now }
+options[:committer] = { :email => "testuser at github.com", :name => 'Test Author', :time => Time.now }
+options[:message] ||= "Making a commit via Rugged!"
+options[:parents] = repo.empty? ? [] : [ repo.head.target ].compact
+options[:update_ref] = 'HEAD'
+
+Rugged::Commit.create(repo, options)
+```
+
+---
+
+### Commit Walker
+
+`Rugged::Walker` is a class designed to help you traverse a set of commits over
+a repository.
+
+You first push head SHAs onto the walker, and then call next to get a list of
+the reachable commit objects one at a time. You can also `hide()` commits if you
+are not interested in anything beneath them (useful in situations like when
+you're running something like `git log master ^origin/master`).
+
+```ruby
+walker = Rugged::Walker.new(repo)
+walker.sorting(Rugged::SORT_TOPO | Rugged::SORT_REVERSE) # optional
+walker.push(hex_sha_interesting)
+walker.hide(hex_sha_uninteresting)
+walker.each { |c| puts c.inspect }
+walker.reset
+```
+
+---
+
+### Index ("staging") area
+
+We can inspect and manipulate the Git Index as well. To work with the index
+inside an existing repository, instantiate it by using the `Repository.index`
+method instead of manually opening the Index by its path.
+
+```ruby
+index = Rugged::Index.new(path)
+
+# Re-read the index file from disk.
+index.reload
+
+# Count up index entries.
+count = index.count
+
+# The collection of index entries.
+index.entries
+
+# Iterating over index entries.
+index.each { |i| puts i.inspect }
+
+# Get a particular entry in the index.
+index[path]
+
+# Unstage.
+index.remove(path)
+
+# Stage. Also updates existing entry if there is one.
+index.add(ientry)
+
+# Stage. Create ientry from file in path, updates the index.
+index.add(path)
+```
+
+---
+
+### Refs
+
+The `Rugged::Reference` class allows you to list, create and delete packed and loose refs.
+
+```ruby
+ref = repo.head # or...
+ref = Rugged::Reference.lookup(repo, "refs/heads/master")
+
+sha = ref.target
+str = ref.type   # :direct
+str = ref.name   # "refs/heads/master"
+```
+
+You can also easily get an array of references:
+
+```ruby
+repo.refs.each do |ref|
+  puts ref.name
+end
+```
+
+Or use a pattern (regex):
+
+```ruby
+repo.refs(/tags/).each do |ref|
+  puts ref.name
+end
+```
+
+It is also easy to create, update, rename or delete a reference:
+
+```ruby
+ref = Rugged::Reference.create(repo, "refs/heads/unit_test", some_commit_sha)
+
+ref.set_target(new_sha)
+
+ref.rename("refs/heads/blead")
+
+ref.delete!
+```
+
+Finally, you can access the reflog for any branch:
+
+```ruby
+ref = Rugged::Reference.lookup(repo, "refs/heads/master")
+entry = ref.log.first
+sha   = entry[:id_old]
+sha   = entry[:id_new]
+str   = entry[:message]
+prsn  = entry[:committer]
+```
+
+---
+
+### Branches
+
+`Rugged::Branch` will help you with all of your branch-related needs.
+
+Iterate over all branches:
+
+```ruby
+Rugged::Branch.each_name(repo).sort
+# => ["master", "origin/HEAD", "origin/master", "origin/packed"]
+
+Rugged::Branch.each_name(repo, :local).sort
+# => ["master"]
+
+Rugged::Branch.each_name(repo, :remote).sort
+# => ["origin/HEAD", "origin/master", "origin/packed"]
+```
+
+Look up branches and get attributes:
+
+```ruby
+branch = Rugged::Branch.lookup(repo, "master")
+branch.name # => 'master'
+branch.canonical_name # => 'refs/heads/master'
+```
+
+Look up the oid for the tip of a branch:
+
+```ruby
+Rugged::Branch.lookup(repo, "master").tip.oid
+# => "36060c58702ed4c2a40832c51758d5344201d89a"
+```
+
+Creation and deletion:
+
+```ruby
+branch = repo.create_branch("test_branch")
+branch.move("new_branch")
+branch.delete!
+```
+
+---
+
+### Config files
+
+It's also easy to read and manipulate the Git config file data with Rugged.
+
+```ruby
+# Read values
+repo.config['core.bare']
+
+# Set values
+repo.config['user.name'] = true
+
+# Delete values
+repo.config.delete('user.name')
+```
+
+---
+
+### General methods
+
+Rugged also includes a general library for handling basic Git operations. One of
+these is converting a raw sha (20 bytes) into a readable hex sha (40
+characters).
+
+```ruby
+Rugged.hex_to_raw('bfde59cdd0dfac1d892814f66a95641abd8a1faf')
+# => "\277\336Y\315\320\337\254\035\211(\024\366j\225d\032\275\212\037\257"
+
+Rugged.raw_to_hex("\277\336Y\315\320\337\254\035\211(\024\366j\225d\032\275\212\037\257")
+=> "bfde59cdd0dfac1d892814f66a95641abd8a1faf"
+```

+
+v0.23
+------
+
+### Changes or improvements
+
+* Patience and minimal diff drivers can now be used for merges.
+
+* Merges can now ignore whitespace changes.
+
+* Updated binary identification in CRLF filtering to avoid false positives in
+  UTF-8 files.
+
+* Rename and copy detection is enabled for small files.
+
+* Checkout can now handle an initial checkout of a repository, making
+  `GIT_CHECKOUT_SAFE_CREATE` unnecessary for users of clone.
+
+* The signature parameter in the ref-modifying functions has been
+  removed. Use `git_repository_set_ident()` and
+  `git_repository_ident()` to override the signature to be used.
+
+* The local transport now auto-scales the number of threads to use
+  when creating the packfile instead of sticking to one.
+
+* Reference renaming now uses the right id for the old value.
+
+* The annotated version of branch creation, HEAD detaching and reset
+  allow for specifying the expression from the user to be put into the
+  reflog.
+
+* `git_rebase_commit` now returns `GIT_EUNMERGED` when you attempt to
+  commit with unstaged changes.
+
+* On Mac OS X, we now use SecureTransport to provide the cryptographic
+  support for HTTPS connections insead of OpenSSL.
+
+* Checkout can now accept an index for the baseline computations via the
+  `baseline_index` member.
+
+* The configuration for fetching is no longer stored inside the
+  `git_remote` struct but has been moved to a `git_fetch_options`. The
+  remote functions now take these options or the callbacks instead of
+  setting them beforehand.
+
+* `git_submodule` instances are no longer cached or shared across
+  lookup. Each submodule represents the configuration at the time of
+  loading.
+
+* The index now uses diffs for `add_all()` and `update_all()` which
+  gives it a speed boost and closer semantics to git.
+
+* The ssh transport now reports the stderr output from the server as
+  the error message, which allows you to get the "repository not
+  found" messages.
+
+* `git_index_conflict_add()` will remove staged entries that exist for
+  conflicted paths.
+
+* The flags for a `git_diff_file` will now have the `GIT_DIFF_FLAG_EXISTS`
+  bit set when a file exists on that side of the diff.  This is useful
+  for understanding whether a side of the diff exists in the presence of
+  a conflict.
+
+* The constructor for a write-stream into the odb now takes
+  `git_off_t` instead of `size_t` for the size of the blob, which
+  allows putting large files into the odb on 32-bit systems.
+
+* The remote's push and pull URLs now honor the url.$URL.insteadOf
+  configuration. This allows modifying URL prefixes to a custom
+  value via gitconfig.
+
+* `git_diff_foreach`, `git_diff_blobs`, `git_diff_blob_to_buffer`,
+  and `git_diff_buffers` now accept a new binary callback of type
+  `git_diff_binary_cb` that includes the binary diff information.
+
+* The race condition mitigations described in `racy-git.txt` have been
+  implemented.
+
+* If libcurl is installed, we will use it to connect to HTTP(S)
+  servers.
+
+### API additions
+
+* The `git_merge_options` gained a `file_flags` member.
+
+* Parsing and retrieving a configuration value as a path is exposed
+  via `git_config_parse_path()` and `git_config_get_path()`
+  respectively.
+
+* `git_repository_set_ident()` and `git_repository_ident()` serve to
+  set and query which identity will be used when writing to the
+  reflog.
+
+* `git_config_entry_free()` frees a config entry.
+
+* `git_config_get_string_buf()` provides a way to safely retrieve a
+  string from a non-snapshot configuration.
+
+* `git_annotated_commit_from_revspec()` allows to get an annotated
+  commit from an extended sha synatx string.
+
+* `git_repository_set_head_detached_from_annotated()`,
+  `git_branch_create_from_annotated()` and
+  `git_reset_from_annotated()` allow for the caller to provide an
+  annotated commit through which they can control what expression is
+  put into the reflog as the source/target.
+
+* `git_index_add_frombuffer()` can now create a blob from memory
+  buffer and add it to the index which is attached to a repository.
+
+* The structure `git_fetch_options` has been added to determine the
+  runtime configuration for fetching, such as callbacks, pruning and
+  autotag behaviour. It has the runtime initializer
+  `git_fetch_init_options()`.
+
+* The enum `git_fetch_prune_t` has been added, letting you specify the
+  pruning behaviour for a fetch.
+
+* A push operation will notify the caller of what updates it indends
+  to perform on the remote, which provides similar information to
+  git's pre-push hook.
+
+* `git_stash_apply()` can now apply a stashed state from the stash list,
+  placing the data into the working directory and index.
+
+* `git_stash_pop()` will apply a stashed state (like `git_stash_apply()`)
+  but will remove the stashed state after a successful application.
+
+* A new error code `GIT_EEOF` indicates an early EOF from the
+  server. This typically indicates an error with the URL or
+  configuration of the server, and tools can use this to show messages
+  about failing to communicate with the server.
+
+* A new error code `GIT_EINVALID` indicates that an argument to a
+  function is invalid, or an invalid operation was requested.
+
+* `git_diff_index_to_workdir()` and `git_diff_tree_to_index()` will now
+  produce deltas of type `GIT_DELTA_CONFLICTED` to indicate that the index
+  side of the delta is a conflict.
+
+* The `git_status` family of functions will now produce status of type
+  `GIT_STATUS_CONFLICTED` to indicate that a conflict exists for that file
+  in the index.
+
+* `git_index_entry_is_conflict()` is a utility function to determine if
+  a given index entry has a non-zero stage entry, indicating that it is
+  one side of a conflict.
+
+* It is now possible to pass a keypair via a buffer instead of a
+  path. For this, `GIT_CREDTYPE_SSH_MEMORY` and
+  `git_cred_ssh_key_memory_new()` have been added.
+
+* `git_filter_list_contains` will indicate whether a particular
+  filter will be run in the given filter list.
+
+* `git_commit_header_field()` has been added, which allows retrieving
+  the contents of an arbitrary header field.
+
+* `git_submodule_set_branch()` allows to set the configured branch for
+  a submodule.
+
+### API removals
+
+* `git_remote_save()` and `git_remote_clear_refspecs()` have been
+  removed. Remote's configuration is changed via the configuration
+  directly or through a convenience function which performs changes to
+  the configuration directly.
+
+* `git_remote_set_callbacks()`, `git_remote_get_callbacks()` and
+  `git_remote_set_transport()` have been removed and the remote no
+  longer stores this configuration.
+
+* `git_remote_set_fetch_refpecs()` and
+  `git_remote_set_push_refspecs()` have been removed. There is no
+  longer a way to set the base refspecs at run-time.
+
+* `git_submodule_save()` has been removed. The submodules are no
+  longer configured via the objects.
+
+* `git_submodule_reload_all()` has been removed as we no longer cache
+  submodules.
+
+### Breaking API changes
+
+* `git_smart_subtransport_cb` now has a `param` parameter.
+
+* The `git_merge_options` structure member `flags` has been renamed
+  to `tree_flags`.
+
+* The `git_merge_file_options` structure member `flags` is now
+  an unsigned int. It was previously a `git_merge_file_flags_t`.
+
+* `GIT_CHECKOUT_SAFE_CREATE` has been removed.  Most users will generally
+  be able to switch to `GIT_CHECKOUT_SAFE`, but if you require missing
+  file handling during checkout, you may now use `GIT_CHECKOUT_SAFE |
+  GIT_CHECKOUT_RECREATE_MISSING`.
+
+* The `git_clone_options` and `git_submodule_update_options`
+  structures no longer have a `signature` field.
+
+* The following functions have removed the signature and/or log message
+  parameters in favour of git-emulating ones.
+
+    * `git_branch_create()`, `git_branch_move()`
+    * `git_rebase_init()`, `git_rebase_abort()`
+    * `git_reference_symbolic_create_matching()`,
+      `git_reference_symbolic_create()`, `git_reference_create()`,
+      `git_reference_create_matching()`,
+      `git_reference_symbolic_set_target()`,
+      `git_reference_set_target()`, `git_reference_rename()`
+    * `git_remote_update_tips()`, `git_remote_fetch()`, `git_remote_push()`
+    * `git_repository_set_head()`,
+      `git_repository_set_head_detached()`,
+      `git_repository_detach_head()`
+    * `git_reset()`
+
+* `git_config_get_entry()` now gives back a ref-counted
+  `git_config_entry`. You must free it when you no longer need it.
+
+* `git_config_get_string()` will return an error if used on a
+  non-snapshot configuration, as there can be no guarantee that the
+  returned pointer is valid.
+
+* `git_note_default_ref()` now uses a `git_buf` to return the string,
+  as the string is otherwise not guaranteed to stay allocated.
+
+* `git_rebase_operation_current()` will return `GIT_REBASE_NO_OPERATION`
+  if it is called immediately after creating a rebase session but before
+  you have applied the first patch.
+
+* `git_rebase_options` now contains a `git_checkout_options` struct
+  that will be used for functions that modify the working directory,
+  namely `git_checkout_init`, `git_checkout_next` and
+  `git_checkout_abort`.  As a result, `git_rebase_open` now also takes
+  a `git_rebase_options` and only the `git_rebase_init` and
+  `git_rebase_open` functions take a `git_rebase_options`, where they
+  will persist the options to subsequent `git_rebase` calls.
+
+* The `git_clone_options` struct now has fetch options in a
+  `fetch_opts` field instead of remote callbacks in
+  `remote_callbacks`.
+
+* The remote callbacks has gained a new member `push_negotiation`
+  which gets called before sending the update commands to the server.
+
+* The following functions no longer act on a remote instance but
+  change the repository's configuration. Their signatures have changed
+  accordingly:
+
+    * `git_remote_set_url()`, `git_remote_seturl()`
+    * `git_remote_add_fetch()`, `git_remote_add_push()` and
+    * `git_remote_set_autotag()`
+
+* `git_remote_connect()` and `git_remote_prune()` now take a pointer
+  to the callbacks.
+
+* `git_remote_fetch()` and `git_remote_download()` now take a pointer
+  to fetch options which determine the runtime configuration.
+
+* The `git_remote_autotag_option_t` values have been changed. It has
+  gained a `_UNSPECIFIED` default value to specify no override for the
+  configured setting.
+
+* `git_remote_update_tips()` now takes a pointer to the callbacks as
+  well as a boolean whether to write `FETCH_HEAD` and the autotag
+  setting.
+
+* `git_remote_create_anonymous()` no longer takes a fetch refspec as
+  url-only remotes cannot have configured refspecs.
+
+* The `git_submodule_update_options` struct now has fetch options in
+  the `fetch_opts` field instead of callbacks in the
+  `remote_callbacks` field.
+
+* The following functions no longer act on a submodule instance but
+  change the repository's configuration. Their signatures have changed
+  accordingly:
+
+    * `git_submodule_set_url()`, `git_submodule_set_ignore()`,
+      `git_submodule_set_update()`,
+      `git_submodule_set_fetch_recurse_submodules()`.
+
+* `git_submodule_status()` no longer takes a submodule instance but a
+  repsitory, a submodule name and an ignore setting.
+
+* The `push` function in the `git_transport` interface now takes a
+  pointer to the remote callbacks.
+
+* The `git_index_entry` struct's fields' types have been changed to
+  more accurately reflect what is in fact stored in the
+  index. Specifically, time and file size are 32 bits intead of 64, as
+  these values are truncated.
+
+* `GIT_EMERGECONFLICT` is now `GIT_ECONFLICT`, which more accurately
+  describes the nature of the error.
+
+* It is no longer allowed to call `git_buf_grow()` on buffers
+  borrowing the memory they point to.
+
+v0.22
+------
+
+### Changes or improvements
+
+* `git_signature_new()` now requires a non-empty email address.
+
+* Use CommonCrypto libraries for SHA-1 calculation on Mac OS X.
+
+* Disable SSL compression and SSLv2 and SSLv3 ciphers in favor of TLSv1
+  in OpenSSL.
+
+* The fetch behavior of remotes with autotag set to `GIT_REMOTE_DOWNLOAD_TAGS_ALL`
+  has been changed to match git 1.9.0 and later. In this mode, libgit2 now
+  fetches all tags in addition to whatever else needs to be fetched.
+
+* `git_checkout()` now handles case-changing renames correctly on
+  case-insensitive filesystems; for example renaming "readme" to "README".
+
+* The search for libssh2 is now done via pkg-config instead of a
+  custom search of a few directories.
+
+* Add support for core.protectHFS and core.protectNTFS. Add more
+  validation for filenames which we write such as references.
+
+* The local transport now generates textual progress output like
+  git-upload-pack does ("counting objects").
+
+* `git_checkout_index()` can now check out an in-memory index that is not
+  necessarily the repository's index, so you may check out an index
+  that was produced by git_merge and friends while retaining the cached
+  information.
+
+* Remove the default timeout for receiving / sending data over HTTP using
+  the WinHTTP transport layer.
+
+* Add SPNEGO (Kerberos) authentication using GSSAPI on Unix systems.
+
+* Provide built-in objects for the empty blob (e69de29) and empty
+  tree (4b825dc) objects.
+
+* The index' tree cache is now filled upon read-tree and write-tree
+  and the cache is written to disk.
+
+* LF -> CRLF filter refuses to handle mixed-EOL files
+
+* LF -> CRLF filter now runs when * text = auto (with Git for Windows 1.9.4)
+
+* File unlocks are atomic again via rename. Read-only files on Windows are
+  made read-write if necessary.
+
+* Share open packfiles across repositories to share descriptors and mmaps.
+
+* Use a map for the treebuilder, making insertion O(1)
+
+* The build system now accepts an option EMBED_SSH_PATH which when set
+  tells it to include a copy of libssh2 at the given location. This is
+  enabled for MSVC.
+
+* Add support for refspecs with the asterisk in the middle of a
+  pattern.
+
+* Fetching now performs opportunistic updates. To achieve this, we
+  introduce a difference between active and passive refspecs, which
+  make `git_remote_download()` and `git_remote_fetch()` to take a list of
+  resfpecs to be the active list, similarly to how git fetch accepts a
+  list on the command-line.
+
+* The THREADSAFE option to build libgit2 with threading support has
+  been flipped to be on by default.
+
+* The remote object has learnt to prune remote-tracking branches. If
+  the remote is configured to do so, this will happen via
+  `git_remote_fetch()`. You can also call `git_remote_prune()` after
+  connecting or fetching to perform the prune.
+
+
+### API additions
+
+* Introduce `git_buf_text_is_binary()` and `git_buf_text_contains_nul()` for
+  consumers to perform binary detection on a git_buf.
+
+* `git_branch_upstream_remote()` has been introduced to provide the
+  branch.<name>.remote configuration value.
+
+* Introduce `git_describe_commit()` and `git_describe_workdir()` to provide
+  a description of the current commit (and working tree, respectively)
+  based on the nearest tag or reference
+
+* Introduce `git_merge_bases()` and the `git_oidarray` type to expose all
+  merge bases between two commits.
+
+* Introduce `git_merge_bases_many()` to expose all merge bases between
+  multiple commits.
+
+* Introduce rebase functionality (using the merge algorithm only).
+  Introduce `git_rebase_init()` to begin a new rebase session,
+  `git_rebase_open()` to open an in-progress rebase session,
+  `git_rebase_commit()` to commit the current rebase operation,
+  `git_rebase_next()` to apply the next rebase operation,
+  `git_rebase_abort()` to abort an in-progress rebase and `git_rebase_finish()`
+  to complete a rebase operation.
+
+* Introduce `git_note_author()` and `git_note_committer()` to get the author
+  and committer information on a `git_note`, respectively.
+
+* A factory function for ssh has been added which allows to change the
+  path of the programs to execute for receive-pack and upload-pack on
+  the server, `git_transport_ssh_with_paths()`.
+
+* The ssh transport supports asking the remote host for accepted
+  credential types as well as multiple challeges using a single
+  connection. This requires to know which username you want to connect
+  as, so this introduces the USERNAME credential type which the ssh
+  transport will use to ask for the username.
+
+* The `GIT_EPEEL` error code has been introduced when we cannot peel a tag
+  to the requested object type; if the given object otherwise cannot be
+  peeled, `GIT_EINVALIDSPEC` is returned.
+
+* Introduce `GIT_REPOSITORY_INIT_RELATIVE_GITLINK` to use relative paths
+  when writing gitlinks, as is used by git core for submodules.
+
+* `git_remote_prune()` has been added. See above for description.
+
+
+* Introduce reference transactions, which allow multiple references to
+  be locked at the same time and updates be queued. This also allows
+  us to safely update a reflog with arbitrary contents, as we need to
+  do for stash.

+* `git_remote_supported_url()` and `git_remote_is_valid_url()` have been
+  removed as they have become essentially useless with rsync-style ssh paths.
+
+* `git_clone_into()` and `git_clone_local_into()` have been removed from the
+  public API in favour of `git_clone callbacks`.
+
+* The option to ignore certificate errors via `git_remote_cert_check()`
+  is no longer present. Instead, `git_remote_callbacks` has gained a new
+  entry which lets the user perform their own certificate checks.
+
+### Breaking API changes
+
+* `git_cherry_pick()` is now `git_cherrypick()`.
+
+* The `git_submodule_update()` function was renamed to
+  `git_submodule_update_strategy()`. `git_submodule_update()` is now used to
+  provide functionalty similar to "git submodule update".
+
+* `git_treebuilder_create()` was renamed to `git_treebuilder_new()` to better
+  reflect it being a constructor rather than something which writes to
+  disk.
+
+* `git_treebuilder_new()` (was `git_treebuilder_create()`) now takes a
+  repository so that it can query repository configuration.
+  Subsequently, `git_treebuilder_write()` no longer takes a repository.
+
+* `git_threads_init()` and `git_threads_shutdown()` have been renamed to
+  `git_libgit2_init()` and `git_libgit2_shutdown()` to better explain what
+  their purpose is, as it's grown to be more than just about threads.
+
+* `git_libgit2_init()` and `git_libgit2_shutdown()` now return the number of
+  initializations of the library, so consumers may schedule work on the
+  first initialization.
+
+* The `git_transport_register()` function no longer takes a priority and takes
+  a URL scheme name (eg "http") instead of a prefix like "http://"
+
+* `git_index_name_entrycount()` and `git_index_reuc_entrycount()` now
+  return size_t instead of unsigned int.
+
+* The `context_lines` and `interhunk_lines` fields in `git_diff`_options are
+  now `uint32_t` instead of `uint16_t`. This allows to set them to `UINT_MAX`,
+  in effect asking for "infinite" context e.g. to iterate over all the
+  unmodified lines of a diff.
+
+* `git_status_file()` now takes an exact path. Use `git_status_list_new()` if
+  pathspec searching is needed.
+
+* `git_note_create()` has changed the position of the notes reference
+  name to match `git_note_remove()`.
+
+* Rename `git_remote_load()` to `git_remote_lookup()` to bring it in line
+  with the rest of the lookup functions.
+
+* `git_remote_rename()` now takes the repository and the remote's
+  current name. Accepting a remote indicates we want to change it,
+  which we only did partially. It is much clearer if we accept a name
+  and no loaded objects are changed.
+
+* `git_remote_delete()` now accepts the repository and the remote's name
+  instead of a loaded remote.
+
+* `git_merge_head` is now `git_annotated_commit`, to better reflect its usage
+  for multiple functions (including rebase)
+
+* The `git_clone_options` struct no longer provides the `ignore_cert_errors` or
+  `remote_name` members for remote customization.
+
+  Instead, the `git_clone_options` struct has two new members, `remote_cb` and
+  `remote_cb_payload`, which allow the caller to completely override the remote
+  creation process. If needed, the caller can use this callback to give their
+  remote a name other than the default (origin) or disable cert checking.
+
+  The `remote_callbacks` member has been preserved for convenience, although it
+  is not used when a remote creation callback is supplied.
+
+* The `git_clone`_options struct now provides `repository_cb` and
+  `repository_cb_payload` to allow the user to create a repository with
+  custom options.
+
+* The `git_push` struct to perform a push has been replaced with
+  `git_remote_upload()`. The refspecs and options are passed as a
+  function argument. `git_push_update_tips()` is now also
+  `git_remote_update_tips()` and the callbacks are in the same struct as
+  the rest.
+
+* The `git_remote_set_transport()` function now sets a transport factory function,
+  rather than a pre-existing transport instance.
+
+* The `git_transport` structure definition has moved into the sys/transport.h
+  file.
+
+* libgit2 no longer automatically sets the OpenSSL locking
+  functions. This is not something which we can know to do. A
+  last-resort convenience function is provided in sys/openssl.h,
+  `git_openssl_set_locking()` which can be used to set the locking.

+# Welcome to libgit2!
+
+We're making it easy to do interesting things with git, and we'd love to have
+your help.
+
+## Licensing
+
+By contributing to libgit2, you agree to release your contribution under
+the terms of the license.  Except for the `examples` directory, all code
+is released under the [GPL v2 with linking exception](COPYING).
+
+The `examples` code is governed by the
+[CC0 Public Domain Dedication](examples/COPYING), so that you may copy
+from them into your own application.
+
+## Discussion & Chat
+
+We hang out in the
+[`#libgit2`](http://webchat.freenode.net/?channels=#libgit2)) channel on
+irc.freenode.net.
+
+Also, feel free to open an
+[Issue](https://github.com/libgit2/libgit2/issues/new) to start a discussion
+about any concerns you have.  We like to use Issues for that so there is an
+easily accessible permanent record of the conversation.
+
+## Libgit2 Versions
+
+The `master` branch is the main branch where development happens.
+Releases are tagged
+(e.g. [v0.21.0](https://github.com/libgit2/libgit2/releases/tag/v0.21.0) )
+and when a critical bug fix needs to be backported, it will be done on a
+`<tag>-maint` maintenance branch.
+
+## Reporting Bugs
+
+First, know which version of libgit2 your problem is in and include it in
+your bug report.  This can either be a tag (e.g.
+[v0.17.0](https://github.com/libgit2/libgit2/releases/tag/v0.17.0)) or a
+commit SHA
+(e.g. [01be7863](https://github.com/libgit2/libgit2/commit/01be7863)).
+Using [`git describe`](http://git-scm.com/docs/git-describe) is a
+great way to tell us what version you're working with.
+
+If you're not running against the latest `master` branch version,
+please compile and test against that to avoid re-reporting an issue that's
+already been fixed.
+
+It's *incredibly* helpful to be able to reproduce the problem.  Please
+include a list of steps, a bit of code, and/or a zipped repository (if
+possible).  Note that some of the libgit2 developers are employees of
+GitHub, so if your repository is private, find us on IRC and we'll figure
+out a way to help you.
+
+## Pull Requests
+
+Our work flow is a [typical GitHub
+flow](https://guides.github.com/introduction/flow/index.html), where
+contributors fork the [libgit2 repository](https://github.com/libgit2/libgit2),
+make their changes on branch, and submit a
+[Pull Request](https://help.github.com/articles/using-pull-requests)
+(a.k.a. "PR").  Pull requests should usually be targeted at the `master`
+branch.
+
+Life will be a lot easier for you (and us) if you follow this pattern
+(i.e. fork, named branch, submit PR).  If you use your fork's `master`
+branch directly, things can get messy.
+
+Please include a nice description of your changes when you submit your PR;
+if we have to read the whole diff to figure out why you're contributing
+in the first place, you're less likely to get feedback and have your change
+merged in.
+
+If you are starting to work on a particular area, feel free to submit a PR
+that highlights your work in progress (and note in the PR title that it's
+not ready to merge). These early PRs are welcome and will help in getting
+visibility for your fix, allow others to comment early on the changes and
+also let others know that you are currently working on something.
+
+Before wrapping up a PR, you should be sure to:
+
+* Write tests to cover any functional changes
+* Update documentation for any changed public APIs
+* Add to the [`CHANGELOG.md`](CHANGELOG.md) file describing any major changes
+
+## Unit Tests
+
+We believe that our unit tests allow us to keep the quality of libgit2
+high: any new changes must not cause unit test failures, and new changes
+should include unit tests that cover the bug fixes or new features.
+For bug fixes, we prefer unit tests that illustrate the failure before
+the change, but pass with your changes.
+
+In addition to new tests, please ensure that your changes do not cause
+any other test failures.  Running the entire test suite is helpful
+before you submit a pull request.  When you build libgit2, the test
+suite will also be built.  You can run all tests by simply running
+the resultant `libgit2_clar` binary.  If you want to run a specific
+unit test, you can name it with the `-s` option.  For example:
+
+    libgit2_clar -sstatus::worktree::long_filenames
+
+Or you can run an entire class of tests.  For example, to run all the
+worktree status tests:
+
+    libgit2_clar -sstatus::worktree
+
+## Porting Code From Other Open-Source Projects
+
+`libgit2` is licensed under the terms of the GPL v2 with a linking
+exception.  Any code brought in must be compatible with those terms.
+
+The most common case is porting code from core Git.  Git is a pure GPL
+project, which means that in order to port code to this project, we need the
+explicit permission of the author.  Check the
+[`git.git-authors`](https://github.com/libgit2/libgit2/blob/development/git.git-authors)
+file for authors who have already consented.
+
+Other licenses have other requirements; check the license of the library
+you're porting code *from* to see what you need to do.  As a general rule,
+MIT and BSD (3-clause) licenses are typically no problem.  Apache 2.0
+license typically doesn't work due to GPL incompatibility.
+
+If your pull request uses code from core Git, another project, or code
+from a forum / Stack Overflow, then *please* flag this in your PR and make
+sure you've given proper credit to the original author in the code
+snippet.
+
+## Style Guide
+
+The public API of `libgit2` is [ANSI C](http://en.wikipedia.org/wiki/ANSI_C)
+(a.k.a. C89) compatible.  Internally, `libgit2` is written using a portable
+subset of C99 - in order to compile with GCC, Clang, MSVC, etc., we keep
+local variable declarations at the tops of blocks only and avoid `//` style
+comments.  Additionally, `libgit2` follows some extra conventions for
+function and type naming, code formatting, and testing.
+
+We like to keep the source code consistent and easy to read.  Maintaining
+this takes some discipline, but it's been more than worth it.  Take a look
+at the [conventions
+file](https://github.com/libgit2/libgit2/blob/development/CONVENTIONS.md).
+

+list](https://github.com/libgit2/libgit2/blob/development/PROJECTS.md).

+# Libgit2 Conventions
+
+We like to keep the source consistent and readable.  Herein are some
+guidelines that should help with that.
+
+## Compatibility
+
+`libgit2` runs on many different platforms with many different compilers.
+
+The public API of `libgit2` is [ANSI C](http://en.wikipedia.org/wiki/ANSI_C)
+(a.k.a. C89) compatible.
+
+Internally, `libgit2` is written using a portable subset of C99 - in order
+to maximize compatibility (e.g. with MSVC) we avoid certain C99
+extensions.  Specifically, we keep local variable declarations at the tops
+of blocks only and we avoid `//` style comments.
+
+Also, to the greatest extent possible, we try to avoid lots of `#ifdef`s
+inside the core code base.  This is somewhat unavoidable, but since it can
+really hamper maintainability, we keep it to a minimum.
+
+## Match Surrounding Code
+
+If there is one rule to take away from this document, it is *new code should
+match the surrounding code in a way that makes it impossible to distinguish
+the new from the old.* Consistency is more important to us than anyone's
+personal opinion about where braces should be placed or spaces vs. tabs.
+
+If a section of code is being completely rewritten, it is okay to bring it
+in line with the standards that are laid out here, but we will not accept
+submissions that contain a large number of changes that are merely
+reformatting.
+
+## Naming Things
+
+All external types and functions start with `git_` and all `#define` macros
+start with `GIT_`.  The `libgit2` API is mostly broken into related
+functional modules each with a corresponding header.  All functions in a
+module should be named like `git_modulename_functioname()`
+(e.g. `git_repository_open()`).
+
+Functions with a single output parameter should name that parameter `out`.
+Multiple outputs should be named `foo_out`, `bar_out`, etc.
+
+Parameters of type `git_oid` should be named `id`, or `foo_id`.  Calls that
+return an OID should be named `git_foo_id`.
+
+Where a callback function is used, the function should also include a
+user-supplied extra input that is a `void *` named "payload" that will be
+passed through to the callback at each invocation.
+
+## Typedefs
+
+Wherever possible, use `typedef`.  In some cases, if a structure is just a
+collection of function pointers, the pointer types don't need to be
+separately typedef'd, but loose function pointer types should be.
+
+## Exports
+
+All exported functions must be declared as:
+
+```c
+GIT_EXTERN(result_type) git_modulename_functionname(arg_list);
+```
+
+## Internals
+
+Functions whose *modulename* is followed by two underscores,
+for example `git_odb__read_packed`, are semi-private functions.
+They are primarily intended for use within the library itself,
+and may disappear or change their signature in a future release.
+
+## Parameters
+
+Out parameters come first.
+
+Whenever possible, pass argument pointers as `const`.  Some structures (such
+as `git_repository` and `git_index`) have mutable internal structure that
+prevents this.
+
+Callbacks should always take a `void *` payload as their last parameter.
+Callback pointers are grouped with their payloads, and typically come last
+when passed as arguments:
+
+```c
+int git_foo(git_repository *repo, git_foo_cb callback, void *payload);
+```
+
+## Memory Ownership
+
+Some APIs allocate memory which the caller is responsible for freeing; others
+return a pointer into a buffer that's owned by some other object.  Make this
+explicit in the documentation.
+
+## Return codes
+
+Most public APIs should return an `int` error code.  As is typical with most
+C library functions, a zero value indicates success and a negative value
+indicates failure.
+
+Some bindings will transform these returned error codes into exception
+types, so returning a semantically appropriate error code is important.
+Check
+[`include/git2/errors.h`](https://github.com/libgit2/libgit2/blob/development/include/git2/errors.h)
+for the return codes already defined.
+
+In your implementation, use `giterr_set()` to provide extended error
+information to callers.
+
+If a `libgit2` function internally invokes another function that reports an
+error, but the error is not propagated up, use `giterr_clear()` to prevent
+callers from getting the wrong error message later on.
+
+
+## Structs
+
+Most public types should be opaque, e.g.:
+
+```C
+typedef struct git_odb git_odb;
+```
+
+...with allocation functions returning an "instance" created within
+the library, and not within the application.  This allows the type
+to grow (or shrink) in size without rebuilding client code.
+
+To preserve ABI compatibility, include an `int version` field in all opaque
+structures, and initialize to the latest version in the construction call.
+Increment the "latest" version whenever the structure changes, and try to only
+append to the end of the structure.
+
+## Option Structures
+
+If a function's parameter count is too high, it may be desirable to package
+up the options in a structure.  Make them transparent, include a version
+field, and provide an initializer constant or constructor.  Using these
+structures should be this easy:
+
+```C
+git_foo_options opts = GIT_FOO_OPTIONS_INIT;
+opts.baz = BAZ_OPTION_ONE;
+git_foo(&opts);
+```
+
+## Enumerations
+
+Typedef all enumerated types.  If each option stands alone, use the enum
+type for passing them as parameters; if they are flags to be OR'ed together,
+pass them as `unsigned int` or `uint32_t` or some appropriate type.
+
+## Code Layout
+
+Try to keep lines less than 80 characters long.  This is a loose
+requirement, but going significantly over 80 columns is not nice.
+
+Use common sense to wrap most code lines; public function declarations
+can use a couple of different styles:
+
+```c
+/** All on one line is okay if it fits */
+GIT_EXTERN(int) git_foo_simple(git_oid *id);
+
+/** Otherwise one argument per line is a good next step */
+GIT_EXTERN(int) git_foo_id(
+	git_oid **out,
+	int a,
+	int b);
+```
+
+Indent with tabs; set your editor's tab width to 4 for best effect.
+
+Avoid trailing whitespace and only commit Unix-style newlines (i.e. no CRLF
+in the repository - just set `core.autocrlf` to true if you are writing code
+on a Windows machine).
+
+## Documentation
+
+All comments should conform to Doxygen "javadoc" style conventions for
+formatting the public API documentation.  Try to document every parameter,
+and keep the comments up to date if you change the parameter list.
+
+## Public Header Template
+
+Use this template when creating a new public header.
+
+```C
+#ifndef INCLUDE_git_${filename}_h__
+#define INCLUDE_git_${filename}_h__
+
+#include "git/common.h"
+
+/**
+ * @file git/${filename}.h
+ * @brief Git some description
+ * @defgroup git_${filename} some description routines
+ * @ingroup Git
+ * @{
+ */
+GIT_BEGIN_DECL
+
+/* ... definitions ... */
+
+/** @} */
+GIT_END_DECL
+#endif
+```
+
+## Inlined functions
+
+All inlined functions must be declared as:
+
+```C
+GIT_INLINE(result_type) git_modulename_functionname(arg_list);
+```
+
+`GIT_INLINE` (or `inline`) should not be used in public headers in order
+to preserve ANSI C compatibility.
+
+## Tests
+
+`libgit2` uses the [clar](https://github.com/vmg/clar) testing framework.
+
+All PRs should have corresponding tests.
+
+* If the PR fixes an existing issue, the test should fail prior to applying
+  the PR and succeed after applying it.
+* If the PR is for new functionality, then the tests should exercise that
+  new functionality to a certain extent.  We don't require 100% coverage
+  right now (although we are getting stricter over time).
+
+When adding new tests, we prefer if you attempt to reuse existing test data
+(in `tests-clar/resources/`) if possible.  If you are going to add new test
+repositories, please try to strip them of unnecessary files (e.g. sample
+hooks, etc).

+ In addition to the permissions in the GNU General Public License,

+ version of this library into combinations with other programs,
+ and to distribute those combinations without any restriction
+ coming from the use of this file.  (The General Public License

+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990

+
+That's all there is to it!

+Projects For LibGit2
+====================
+
+So, you want to start helping out with `libgit2`? That's fantastic! We
+welcome contributions and we promise we'll try to be nice.
+
+This is a list of libgit2 related projects that new contributors can take
+on.  It includes a number of good starter projects and well as some larger
+ideas that no one is actively working on.
+
+## Before You Start
+
+Please start by reading the [README.md](README.md),
+[CONTRIBUTING.md](CONTRIBUTING.md), and [CONVENTIONS.md](CONVENTIONS.md)
+files before diving into one of these projects.  Those explain our work
+flow and coding conventions to help ensure that your work will be easily
+integrated into libgit2.
+
+Next, work through the build instructions and make sure you can clone the
+repository, compile it, and run the tests successfully.  That will make
+sure that your development environment is set up correctly and you are
+ready to start on libgit2 development.
+
+## Starter Projects
+
+These are good small projects to get started with libgit2.
+
+* Look at the `examples/` programs, find an existing one that mirrors a
+  core Git command and add a missing command-line option.  There are many
+  gaps right now and this helps demonstrate how to use the library.  Here
+  are some specific ideas (though there are many more):
+    * Fix the `examples/diff.c` implementation of the `-B`
+      (a.k.a. `--break-rewrites`) command line option to actually look for
+      the optional `[<n>][/<m>]` configuration values. There is an
+      existing comment that reads `/* TODO: parse thresholds */`. The
+      trick to this one will be doing it in a manner that is clean and
+      simple, but still handles the various cases correctly (e.g. `-B/70%`
+      is apparently a legal setting).
+    * Implement the `--log-size` option for `examples/log.c`. I think all
+      the data is available, you would just need to add the code into the
+      `print_commit()` routine (along with a way of passing the option
+      into that function).
+    * As an extension to the matching idea for `examples/log.c`, add the
+      `-i` option to use `strcasestr()` for matches.
+    * For `examples/log.c`, implement the `--first-parent` option now that
+      libgit2 supports it in the revwalk API.
+* Pick a Git command that is not already emulated in `examples/` and write
+  a new example that mirrors the behavior.  Examples don't have to be
+  perfect emulations, but should demonstrate how to use the libgit2 APIs
+  to get results that are similar to Git commands.  This lets you (and us)
+  easily exercise a particular facet of the API and measure compatability
+  and feature parity with core git.
+* Submit a PR to clarify documentation! While we do try to document all of
+  the APIs, your fresh eyes on the documentation will find areas that are
+  confusing much more easily.
+
+If none of these appeal to you, take a look at our issues list to see if
+there are any unresolved issues you'd like to jump in on.
+
+## Larger Projects
+
+These are ideas for larger projects mostly taken from our backlog of
+[Issues](https://github.com/libgit2/libgit2/issues).  Please don't dive
+into one of these as a first project for libgit2 - we'd rather get to
+know you first by successfully shipping your work on one of the smaller
+projects above.
+
+Some of these projects are broken down into subprojects and/or have
+some incremental steps listed towards the larger goal.  Those steps
+might make good smaller projects by themselves.
+
+* Port part of the Git test suite to run against the command line emulation
+  in examples/
+    * Pick a Git command that is emulated in our examples/ area
+    * Extract the Git tests that exercise that command
+    * Convert the tests to call our emulation
+    * These tests could go in examples/tests/...
+* Fix symlink support for files in the .git directory (i.e. don't overwrite
+  the symlinks when writing the file contents back out)
+* Add hooks API to enumerate and manage hooks (not run them at this point)
+    * Enumeration of available hooks
+    * Lookup API to see which hooks have a script and get the script
+    * Read/write API to load a hook script and write a hook script
+    * Eventually, callback API to invoke a hook callback when libgit2
+      executes the action in question
+* Isolate logic of ignore evaluation into a standalone API
+* Upgrade internal libxdiff code to latest from core Git
+* Improve index internals with hashtable lookup for files instead of
+  using binary search every time
+* Tree builder improvements:
+    * Extend to allow building a tree hierarchy
+* Apply-patch API
+* Add a patch editing API to enable "git add -p" type operations
+* Textconv API to filter binary data before generating diffs (something
+  like the current Filter API, probably).
+* Performance profiling and improvement
+* Support "git replace" ref replacements
+* Include conflicts in diff results and in status
+    * GIT_DELTA_CONFLICT for items in conflict (with multiple files)
+    * Appropriate flags for status
+* Support sparse checkout (i.e. "core.sparsecheckout" and ".git/info/sparse-checkout")

+libgit2 - the Git linkable library
+==================================
+
+[![Travis Build Status](https://secure.travis-ci.org/libgit2/libgit2.svg?branch=master)](http://travis-ci.org/libgit2/libgit2)
+[![AppVeyor Build Status](https://ci.appveyor.com/api/projects/status/xvof5b4t5480a2q3/branch/master?svg=true)](https://ci.appveyor.com/project/libgit2/libgit2/branch/master)
+[![Coverity Scan Build Status](https://scan.coverity.com/projects/639/badge.svg)](https://scan.coverity.com/projects/639)
+
+`libgit2` is a portable, pure C implementation of the Git core methods
+provided as a re-entrant linkable library with a solid API, allowing you to
+write native speed custom Git applications in any language with bindings.
+
+`libgit2` is licensed under a **very permissive license** (GPLv2 with a special
+Linking Exception).  This basically means that you can link it (unmodified)
+with any kind of software without having to release its source code.
+Additionally, the example code has been released to the public domain (see the
+[separate license](examples/COPYING) for more information).
+
+* Website: [libgit2.github.com](http://libgit2.github.com)
+* StackOverflow Tag: [libgit2](http://stackoverflow.com/questions/tagged/libgit2)
+* Issues: [GitHub Issues](https://github.com/libgit2/libgit2/issues) (Right here!)
+* API documentation: <http://libgit2.github.com/libgit2>
+* IRC: [#libgit2](irc://irc.freenode.net/libgit2) on irc.freenode.net.
+* Mailing list: The libgit2 mailing list was
+    traditionally hosted in Librelist but has been deprecated. We encourage you to
+    [use StackOverflow](http://stackoverflow.com/questions/tagged/libgit2) instead for any questions regarding
+    the library, or [open an issue](https://github.com/libgit2/libgit2/issues)
+    on GitHub for bug reports.  The mailing list archives are still available at
+    <http://librelist.com/browser/libgit2/>.
+
+
+What It Can Do
+==============
+
+`libgit2` is already very usable and is being used in production for many
+applications including the GitHub.com site, in Plastic SCM and also powering
+Microsoft's Visual Studio tools for Git.  The library provides:
+
+* SHA conversions, formatting and shortening
+* abstracted ODB backend system
+* commit, tag, tree and blob parsing, editing, and write-back
+* tree traversal
+* revision walking
+* index file (staging area) manipulation
+* reference management (including packed references)
+* config file management
+* high level repository management
+* thread safety and reentrancy
+* descriptive and detailed error messages
+* ...and more (over 175 different API calls)
+
+Optional dependencies
+=====================
+
+While the library provides git functionality without the need for
+dependencies, it can make use of a few libraries to add to it:
+
+- pthreads (non-Windows) to enable threadsafe access as well as multi-threaded pack generation
+- OpenSSL (non-Windows) to talk over HTTPS and provide the SHA-1 functions
+- LibSSH2 to enable the SSH transport
+- iconv (OSX) to handle the HFS+ path encoding peculiarities
+
+Initialization
+===============
+
+The library needs to keep track of some global state. Call
+
+    git_libgit2_init();
+
+before calling any other libgit2 functions. You can call this function many times. A matching number of calls to
+
+    git_libgit2_shutdown();
+
+will free the resources.  Note that if you have worker threads, you should
+call `git_libgit2_shutdown` *after* those threads have exited.  If you
+require assistance coordinating this, simply have the worker threads call
+`git_libgit2_init` at startup and `git_libgit2_shutdown` at shutdown.
+
+Threading
+=========
+
+See [THREADING](THREADING.md) for information
+
+Building libgit2 - Using CMake
+==============================
+
+`libgit2` builds cleanly on most platforms without any external dependencies.
+Under Unix-like systems, like Linux, \*BSD and Mac OS X, libgit2 expects `pthreads` to be available;
+they should be installed by default on all systems. Under Windows, libgit2 uses the native Windows API
+for threading.
+
+The `libgit2` library is built using [CMake](<http://www.cmake.org>) (version 2.8 or newer) on all platforms.
+
+On most systems you can build the library using the following commands
+
+	$ mkdir build && cd build
+	$ cmake ..
+	$ cmake --build .
+
+Alternatively you can point the CMake GUI tool to the CMakeLists.txt file and generate platform specific build project or IDE workspace.
+
+To install the library you can specify the install prefix by setting:
+
+	$ cmake .. -DCMAKE_INSTALL_PREFIX=/install/prefix
+	$ cmake --build . --target install
+
+For more advanced use or questions about CMake please read <http://www.cmake.org/Wiki/CMake_FAQ>.
+
+The following CMake variables are declared:
+
+- `BIN_INSTALL_DIR`: Where to install binaries to.
+- `LIB_INSTALL_DIR`: Where to install libraries to.
+- `INCLUDE_INSTALL_DIR`: Where to install headers to.
+- `BUILD_SHARED_LIBS`: Build libgit2 as a Shared Library (defaults to ON)
+- `BUILD_CLAR`: Build [Clar](https://github.com/vmg/clar)-based test suite (defaults to ON)
+- `THREADSAFE`: Build libgit2 with threading support (defaults to ON)
+- `STDCALL`: Build libgit2 as `stdcall`. Turn off for `cdecl` (Windows; defaults to ON)
+
+Compiler and linker options
+---------------------------
+
+CMake lets you specify a few variables to control the behavior of the
+compiler and linker. These flags are rarely used but can be useful for
+64-bit to 32-bit cross-compilation.
+
+- `CMAKE_C_FLAGS`: Set your own compiler flags
+- `CMAKE_FIND_ROOT_PATH`: Override the search path for libraries
+- `ZLIB_LIBRARY`, `OPENSSL_SSL_LIBRARY` AND `OPENSSL_CRYPTO_LIBRARY`:
+Tell CMake where to find those specific libraries
+
+MacOS X
+-------
+
+If you want to build a universal binary for Mac OS X, CMake sets it
+all up for you if you use `-DCMAKE_OSX_ARCHITECTURES="i386;x86_64"`
+when configuring.
+
+Windows
+-------
+
+You need to run the CMake commands from the Visual Studio command
+prompt, not the regular or Windows SDK one. Select the right generator
+for your version with the `-G "Visual Studio X" option.
+
+See [the website](https://libgit2.github.com/docs/guides/build-and-link)
+for more detailed instructions.
+
+Android
+-------
+
+Extract toolchain from NDK using, `make-standalone-toolchain.sh` script.
+Optionally, crosscompile and install OpenSSL inside of it. Then create CMake
+toolchain file that configures paths to your crosscompiler (substitute `{PATH}`
+with full path to the toolchain):
+
+	SET(CMAKE_SYSTEM_NAME Linux)
+	SET(CMAKE_SYSTEM_VERSION Android)
+
+	SET(CMAKE_C_COMPILER   {PATH}/bin/arm-linux-androideabi-gcc)
+	SET(CMAKE_CXX_COMPILER {PATH}/bin/arm-linux-androideabi-g++)
+	SET(CMAKE_FIND_ROOT_PATH {PATH}/sysroot/)
+
+	SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
+	SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
+	SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
+
+Add `-DCMAKE_TOOLCHAIN_FILE={pathToToolchainFile}` to cmake command
+when configuring.

+Threads in libgit2
+==================
+
+You may safely use any libgit2 object from any thread, though there
+may be issues depending on the cryptographic libraries libgit2 or its
+dependencies link to (more on this later). For libgit2 itself,
+provided you take the following into consideration you won't run into
+issues:
+
+Sharing objects
+---------------
+
+Use an object from a single thread at a time. Most data structures do
+not guard against concurrent access themselves. This is because they
+are rarely used in isolation and it makes more sense to synchronize
+access via a larger lock or similar mechanism.
+
+There are some objects which are read-only/immutable and are thus safe
+to share across threads, such as references and configuration
+snapshots.
+
+Error messages
+--------------
+
+The error message is thread-local. The `giterr_last()` call must
+happen on the same thread as the error in order to get the
+message. Often this will be the case regardless, but if you use
+something like the [GCD](http://en.wikipedia.org/wiki/Grand_Central_Dispatch)
+on Mac OS X (where code is executed on an arbitrary thread), the code
+must make sure to retrieve the error code on the thread where the error
+happened.
+
+Threads and cryptographic libraries
+=======================================
+
+On Windows
+----------
+
+When built as a native Windows DLL, libgit2 uses WinCNG and WinHTTP,
+both of which are thread-safe. You do not need to do anything special.
+
+When using libssh2 which itself uses WinCNG, there are no special
+steps necessary. If you are using a MinGW or similar environment where
+libssh2 uses OpenSSL or libgcrypt, then the general case affects
+you.
+
+On Mac OS X
+-----------
+
+By default we use libcurl to perform the encryption. The
+system-provided libcurl uses SecureTransport, so no special steps are
+necessary. If you link against another libcurl (e.g. from homebrew)
+refer to the general case.
+
+If the option to use libcurl was deactivated, the library makes use of
+CommonCrypto and SecureTransport for cryptographic support. These are
+thread-safe and you do not need to do anything special.
+
+Note that libssh2 may still use OpenSSL itself. In that case, the
+general case still affects you if you use ssh.
+
+General Case
+------------
+
+By default we use libcurl, which has its own ![recommendations for
+thread safety](http://curl.haxx.se/libcurl/c/libcurl-tutorial.html#Multi-threading).
+
+If libcurl was not found or was disabled, libgit2 uses OpenSSL to be
+able to use HTTPS as a transport. This library is made to be
+thread-implementation agnostic, and the users of the library must set
+which locking function it should use. This means that libgit2 cannot
+know what to set as the user of libgit2 may use OpenSSL independently
+and the locking settings must survive libgit2 shutting down.
+
+libgit2 does provide a last-resort convenience function
+`git_openssl_set_locking()` (available in `sys/openssl.h`) to use the
+platform-native mutex mechanisms to perform the locking, which you may
+rely on if you do not want to use OpenSSL outside of libgit2, or you
+know that libgit2 will outlive the rest of the operations. It is not
+safe to use OpenSSL multi-threaded after libgit2's shutdown function
+has been called.
+
+If your programming language offers a package/bindings for OpenSSL,
+you should very strongly prefer to use that in order to set up
+locking, as they provide a level of coördination which is impossible
+when using this function.
+
+See the
+[OpenSSL documentation](https://www.openssl.org/docs/crypto/threads.html)
+on threading for more details.
+
+Be also aware that libgit2 does not always link against OpenSSL
+if there are alternatives provided by the system.
+
+libssh2 may be linked against OpenSSL or libgcrypt. If it uses
+OpenSSL, you only need to set up threading for OpenSSL once and the
+above paragraphs are enough. If it uses libgcrypt, then you need to
+set up its locking before using it multi-threaded. libgit2 has no
+direct connection to libgcrypt and thus has not convenience functions for
+it (but libgcrypt has macros). Read libgcrypt's
+[threading documentation for more information](http://www.gnupg.org/documentation/manuals/gcrypt/Multi_002dThreading.html)
+
+It is your responsibility as an application author or packager to know
+what your dependencies are linked against and to take the appropriate
+steps to ensure the cryptographic libraries are thread-safe. We agree
+that this situation is far from ideal but at this time it is something
+the application authors need to deal with.

+
+   The former two functions operate on STRING with length LENGTH,

+
+   re_match() matches the compiled pattern in BUFP against the string,

+
+   re_search() first tries matching at index START, then it tries to match

+
+   The parameter STOP of re_{match,search}_2 specifies that no match exceeding
+   the first STOP characters of the concatenation of the strings should be
+   concerned.
+
+   If REGS is not NULL, and BUFP->no_sub is not set, the offsets of the match
+   and all groups is stroed in REGS.  (For the "_2" variants, the offsets are
+   computed relative to the concatenation, not relative to the individual
+   strings.)
+
+   On success, re_match* functions return the length of the match, re_search*
+   return the position of the start of the match.  Return value -1 means no

+  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
+  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit.  Then adding polynomials
+  is just exclusive-or, and multiplying a polynomial by x is a right shift by
+  one.  If we call the above polynomial p, and represent a byte as the
+  polynomial q, also with the lowest power in the most significant bit (so the
+  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder.  The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+  x (which is shifting right by one and adding x^32 mod p if the bit shifted
+  out is a one).  We start with the highest power (least significant bit) of
+  q and repeat for all eight bits of q.
+
+  The first table is simply the CRC of all possible eight bit values.  This is
+  all the information needed to generate CRCs on data a byte at a time for all
+  combinations of CRC register values and incoming bytes.  The remaining tables
+  allow for word-at-a-time CRC calculation for both big-endian and little-
+  endian machines, where a word is four bytes.

+/*
+ *  ALGORITHM
+ *
+ *      The "deflation" process depends on being able to identify portions
+ *      of the input text which are identical to earlier input (within a
+ *      sliding window trailing behind the input currently being processed).
+ *
+ *      The most straightforward technique turns out to be the fastest for
+ *      most input files: try all possible matches and select the longest.
+ *      The key feature of this algorithm is that insertions into the string
+ *      dictionary are very simple and thus fast, and deletions are avoided
+ *      completely. Insertions are performed at each input character, whereas
+ *      string matches are performed only when the previous match ends. So it
+ *      is preferable to spend more time in matches to allow very fast string
+ *      insertions and avoid deletions. The matching algorithm for small
+ *      strings is inspired from that of Rabin & Karp. A brute force approach
+ *      is used to find longer strings when a small match has been found.
+ *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ *      (by Leonid Broukhis).
+ *         A previous version of this file used a more sophisticated algorithm
+ *      (by Fiala and Greene) which is guaranteed to run in linear amortized
+ *      time, but has a larger average cost, uses more memory and is patented.
+ *      However the F&G algorithm may be faster for some highly redundant
+ *      files if the parameter max_chain_length (described below) is too large.
+ *
+ *  ACKNOWLEDGEMENTS
+ *
+ *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ *      I found it in 'freeze' written by Leonid Broukhis.
+ *      Thanks to many people for bug reports and testing.

+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state->mode == LEN
+        strm->avail_in >= 6
+        strm->avail_out >= 258
+        start >= strm->avail_out
+        state->bits < 8
+
+   On return, state->mode is one of:
+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm->avail_in >= 6, then there is enough input to avoid

+ * Copyright (C) 1995-2012 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0    24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ *   creation of window when not needed, minimize use of window when it is
+ *   needed, make inffast.c even faster, implement gzip decoding, and to
+ *   improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1    25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2    4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ *   to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3    22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ *   buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4    1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ *   source file infback.c to provide a call-back interface to inflate for
+ *   programs like gzip and unzip -- uses window as output buffer to avoid
+ *   window copying
+ *
+ * 1.2.beta5    1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ *   input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6    4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ *   make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7    27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0        9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ *   for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ *   and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+   inflate() uses a state machine to process as much input data and generate as
+   much output data as possible before returning.  The state machine is
+   structured roughly as follows:
+
+    for (;;) switch (state) {
+    ...
+    case STATEn:
+        if (not enough input data or output space to make progress)
+            return;
+        ... make progress ...
+        state = STATEm;
+        break;
+    ...
+    }
+
+   so when inflate() is called again, the same case is attempted again, and
+   if the appropriate resources are provided, the machine proceeds to the
+   next state.  The NEEDBITS() macro is usually the way the state evaluates
+   whether it can proceed or should return.  NEEDBITS() does the return if
+   the requested bits are not available.  The typical use of the BITS macros
+   is:
+
+        NEEDBITS(n);
+        ... do something with BITS(n) ...
+        DROPBITS(n);
+
+   where NEEDBITS(n) either returns from inflate() if there isn't enough
+   input left to load n bits into the accumulator, or it continues.  BITS(n)
+   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
+   the low n bits off the accumulator.  INITBITS() clears the accumulator
+   and sets the number of available bits to zero.  BYTEBITS() discards just
+   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
+   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+   if there is no input available.  The decoding of variable length codes uses
+   PULLBYTE() directly in order to pull just enough bytes to decode the next
+   code, and no more.
+
+   Some states loop until they get enough input, making sure that enough
+   state information is maintained to continue the loop where it left off
+   if NEEDBITS() returns in the loop.  For example, want, need, and keep
+   would all have to actually be part of the saved state in case NEEDBITS()
+   returns:
+
+    case STATEw:
+        while (want < need) {
+            NEEDBITS(n);
+            keep[want++] = BITS(n);
+            DROPBITS(n);
+        }
+        state = STATEx;
+    case STATEx:
+
+   As shown above, if the next state is also the next case, then the break
+   is omitted.
+
+   A state may also return if there is not enough output space available to
+   complete that state.  Those states are copying stored data, writing a
+   literal byte, and copying a matching string.
+
+   When returning, a "goto inf_leave" is used to update the total counters,
+   update the check value, and determine whether any progress has been made
+   during that inflate() call in order to return the proper return code.
+   Progress is defined as a change in either strm->avail_in or strm->avail_out.
+   When there is a window, goto inf_leave will update the window with the last
+   output written.  If a goto inf_leave occurs in the middle of decompression
+   and there is no window currently, goto inf_leave will create one and copy
+   output to the window for the next call of inflate().
+
+   In this implementation, the flush parameter of inflate() only affects the
+   return code (per zlib.h).  inflate() always writes as much as possible to
+   strm->next_out, given the space available and the provided input--the effect
+   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
+   the allocation of and copying into a sliding window until necessary, which
+   provides the effect documented in zlib.h for Z_FINISH when the entire input
+   stream available.  So the only thing the flush parameter actually does is:
+   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
+   will return Z_BUF_ERROR if it has not reached the end of the stream.

+       for codes with equal lengths.  Then the code starts with all zero bits
+       for the first code of the shortest length, and the codes are integer

+       increases.  For the deflate format, these bits are stored backwards

+       are incremented backwards.

+       sorted table, and then entering the symbols in order in the sorted
+       table.  The sorted table is work[], with that space being provided by
+       the caller.
+
+       The length counts are used for other purposes as well, i.e. finding
+       the minimum and maximum length codes, determining if there are any
+       codes at all, checking for a valid set of lengths, and looking ahead
+       at length counts to determine sub-table sizes when building the

+  but other algorithms will be added later and will have the same stream
+  interface.
+
+    Compression can be done in a single step if the buffers are large enough,
+  or can be done by repeated calls of the compression function.  In the latter
+  case, the application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+    The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+    The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio using the functions that start
+  with "gz".  The gzip format is different from the zlib format.  gzip is a
+  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+    This library can optionally read and write gzip streams in memory as well.
+
+    The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+    The library does not install any signal handler.  The decoder checks
+  the consistency of the compressed data, so the library should never crash
+  even in case of corrupted input.

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows.  deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).  Some
+    output may be provided even if flush is not set.
+
+    Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating avail_in or avail_out accordingly; avail_out should
+  never be zero before the call.  The application can consume the compressed
+  output when it wants, for example when the output buffer is full (avail_out
+  == 0), or after each call of deflate().  If deflate returns Z_OK and with
+  zero avail_out, it must be called again after making room in the output
+  buffer because there might be more output pending.
+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumulate before producing output, in order to
+  maximize compression.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far.  (In
+  particular avail_in is zero after the call if enough output space has been
+  provided before the call.) Flushing may degrade compression for some
+  compression algorithms and so it should be used only when necessary.  This
+  completes the current deflate block and follows it with an empty stored block
+  that is three bits plus filler bits to the next byte, followed by four bytes
+  (00 00 ff ff).
+
+    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+  output buffer, but the output is not aligned to a byte boundary.  All of the
+  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+  This completes the current deflate block and follows it with an empty fixed
+  codes block that is 10 bits long.  This assures that enough bytes are output
+  in order for the decompressor to finish the block before the empty fixed code
+  block.
+
+    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+  seven bits of the current block are held to be written as the next byte after
+  the next deflate block is completed.  In this case, the decompressor may not
+  be provided enough bits at this point in order to complete decompression of
+  the data provided so far to the compressor.  It may need to wait for the next
+  block to be emitted.  This is for advanced applications that need to control
+  the emission of deflate blocks.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
+  compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+  avail_out is greater than six to avoid repeated flush markers due to
+  avail_out == 0 on return.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there was
+  enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error.  After
+  deflate has returned Z_STREAM_END, the only possible operations on the stream
+  are deflateReset or deflateEnd.
+
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step.  In this case, avail_out must be at least the
+  value returned by deflateBound (see below).  Then deflate is guaranteed to
+  return Z_STREAM_END.  If not enough output space is provided, deflate will
+  not return Z_STREAM_END, and it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update strm->data_type if it can make a good guess about
+  the input data type (Z_BINARY or Z_TEXT).  In doubt, the data is considered
+  binary.  This field is only for information purposes and does not affect the
+  compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+  if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible
+  (for example avail_in or avail_out was zero).  Note that Z_BUF_ERROR is not

+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+  The detailed semantics are as follows.  inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in is updated and processing will
+    resume at this point for the next call of inflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there is
+    no more input data or no more space in the output buffer (see below about
+    the flush parameter).
+
+    Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating the next_* and avail_* values accordingly.  The
+  application can consume the uncompressed output when it wants, for example
+  when the output buffer is full (avail_out == 0), or after each call of
+  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
+  called again after making room in the output buffer because there might be
+  more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer.  Z_BLOCK requests that inflate()
+  stop if and when it gets to the next deflate block boundary.  When decoding
+  the zlib or gzip format, this will cause inflate() to return immediately
+  after the header and before the first block.  When doing a raw inflate,
+  inflate() will go ahead and process the first block, and will return when it
+  gets to the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  Also to assist in this, on return inflate() will set strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64 if
+  inflate() is currently decoding the last block in the deflate stream, plus
+  128 if inflate() returned immediately after decoding an end-of-block code or
+  decoding the complete header up to just before the first byte of the deflate
+  stream.  The end-of-block will not be indicated until all of the uncompressed
+  data from that block has been written to strm->next_out.  The number of
+  unused bits may in general be greater than seven, except when bit 7 of
+  data_type is set, in which case the number of unused bits will be less than
+  eight.  data_type is set as noted here every time inflate() returns for all
+  flush options, and so can be used to determine the amount of currently
+  consumed input in bits.
+
+    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+  end of each deflate block header is reached, before any actual data in that
+  block is decoded.  This allows the caller to determine the length of the
+  deflate block header for later use in random access within a deflate block.
+  256 is added to the value of strm->data_type when inflate() returns
+  immediately after reaching the end of the deflate block header.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error.  However if all decompression is to be performed in a single step (a
+  single call of inflate), the parameter flush should be set to Z_FINISH.  In
+  this case all pending input is processed and all pending output is flushed;
+  avail_out must be large enough to hold all of the uncompressed data for the
+  operation to complete.  (The size of the uncompressed data may have been
+  saved by the compressor for this purpose.) The use of Z_FINISH is not
+  required to perform an inflation in one step.  However it may be used to
+  inform inflate that a faster approach can be used for the single inflate()
+  call.  Z_FINISH also informs inflate to not maintain a sliding window if the
+  stream completes, which reduces inflate's memory footprint.  If the stream
+  does not complete, either because not all of the stream is provided or not
+  enough output space is provided, then a sliding window will be allocated and
+  inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+  been used.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call.  So the effects of the flush parameter in this implementation are
+  on the return value of inflate() as noted below, when inflate() returns early
+  when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+  memory for a sliding window when Z_FINISH is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the Adler-32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below.  At the end of the stream, inflate() checks that its computed adler32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically, if requested when
+  initializing with inflateInit2().  Any information contained in the gzip
+  header is not retained, so applications that need that information should
+  instead use raw inflate, see inflateInit2() below, or inflateBack() and
+  perform their own processing of the gzip header and trailer.  When processing
+  gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+  producted so far.  The CRC-32 is checked against the gzip trailer.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect check
+  value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+  next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
+  Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+  output buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
+  inflate() can be called again with more input and more output space to
+  continue decompressing.  If Z_DATA_ERROR is returned, the application may
+  then call inflateSync() to look for a good compression block if a partial
+  recovery of the data is desired.

+     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
+   determines the window size.  deflate() will then generate raw deflate data
+   with no zlib header or trailer, and will not compute an adler32 check value.
+
+     windowBits can also be greater than 15 for optional gzip encoding.  Add
+   16 to windowBits to write a simple gzip header and trailer around the
+   compressed data instead of a zlib wrapper.  The gzip header will have no
+   file name, no extra data, no comment, no modification time (set to zero), no
+   header crc, and the operating system will be set to 255 (unknown).  If a
+   gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state.  memLevel=1 uses minimum memory but is
+   slow and reduces compression ratio; memLevel=9 uses maximum memory for
+   optimal speed.  The default value is 8.  See zconf.h for total memory usage
+   as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm.  Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match), or Z_RLE to limit match distances to one (run-length
+   encoding).  Filtered data consists mostly of small values with a somewhat
+   random distribution.  In this case, the compression algorithm is tuned to
+   compress them better.  The effect of Z_FILTERED is to force more Huffman
+   coding and less string matching; it is somewhat intermediate between
+   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
+   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
+   strategy parameter only affects the compression ratio but not the
+   correctness of the compressed output even if it is not set appropriately.
+   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+   decoder for special applications.

+
+     The windowBits parameter is the base two logarithm of the maximum window
+   size (the size of the history buffer).  It should be in the range 8..15 for
+   this version of the library.  The default value is 15 if inflateInit is used
+   instead.  windowBits must be greater than or equal to the windowBits value
+   provided to deflateInit2() while compressing, or it must be equal to 15 if

+     windowBits can also be zero to request that inflate use the window size in

+     inflateBack() does a raw inflate with a single call using a call-back
+   interface for input and output.  This is potentially more efficient than
+   inflate() for file i/o applications, in that it avoids copying between the
+   output and the sliding window by simply making the window itself the output
+   buffer.  inflate() can be faster on modern CPUs when used with large
+   buffers.  inflateBack() trusts the application to not change the output
+   buffer passed by the output function, at least until inflateBack() returns.
+
+     inflateBackInit() must be called first to allocate the internal state
+   and to initialize the state with the user-provided window buffer.
+   inflateBack() may then be used multiple times to inflate a complete, raw
+   deflate stream with each call.  inflateBackEnd() is then called to free the
+   allocated state.
+
+     A raw deflate stream is one with no zlib or gzip header or trailer.
+   This routine would normally be used in a utility that reads zip or gzip
+   files and writes out uncompressed files.  The utility would decode the
+   header and process the trailer on its own, hence this routine expects only
+   the raw deflate stream to decompress.  This is different from the normal
+   behavior of inflate(), which expects either a zlib or gzip header and
+   trailer around the deflate stream.
+
+     inflateBack() uses two subroutines supplied by the caller that are then
+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero--buf is ignored in that
+   case--and inflateBack() will return a buffer error.  inflateBack() will call
+   out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].  out()
+   should return zero on success, or non-zero on failure.  If out() returns
+   non-zero, inflateBack() will return with an error.  Neither in() nor out()
+   are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+   in the deflate stream (in which case strm->msg is set to indicate the nature
+   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+   In the case of Z_BUF_ERROR, an input or output error can be distinguished
+   using strm->next_in which will be Z_NULL only if in() returned an error.  If
+   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+   non-zero.  (in() will always be called before out(), so strm->next_in is
+   assured to be defined if out() returns non-zero.) Note that inflateBack()

+Checkout Internals
+==================
+
+Checkout has to handle a lot of different cases.  It examines the
+differences between the target tree, the baseline tree and the working
+directory, plus the contents of the index, and groups files into five
+categories:
+
+1. UNMODIFIED - Files that match in all places.
+2. SAFE - Files where the working directory and the baseline content
+   match that can be safely updated to the target.
+3. DIRTY/MISSING - Files where the working directory differs from the
+   baseline but there is no conflicting change with the target.  One
+   example is a file that doesn't exist in the working directory - no
+   data would be lost as a result of writing this file.  Which action
+   will be taken with these files depends on the options you use.
+4. CONFLICTS - Files where changes in the working directory conflict
+   with changes to be applied by the target.  If conflicts are found,
+   they prevent any other modifications from being made (although there
+   are options to override that and force the update, of course).
+5. UNTRACKED/IGNORED - Files in the working directory that are untracked
+   or ignored (i.e. only in the working directory, not the other places).
+
+Right now, this classification is done via 3 iterators (for the three
+trees), with a final lookup in the index.  At some point, this may move to
+a 4 iterator version to incorporate the index better.
+
+The actual checkout is done in five phases (at least right now).
+
+1. The diff between the baseline and the target tree is used as a base
+   list of possible updates to be applied.
+2. Iterate through the diff and the working directory, building a list of
+   actions to be taken (and sending notifications about conflicts and
+   dirty files).
+3. Remove any files / directories as needed (because alphabetical
+   iteration means that an untracked directory will end up sorted *after*
+   a blob that should be checked out with the same name).
+4. Update all blobs.
+5. Update all submodules (after 4 in case a new .gitmodules blob was
+   checked out)
+
+Checkout could be driven either off a target-to-workdir diff or a
+baseline-to-target diff.  There are pros and cons of each.
+
+Target-to-workdir means the diff includes every file that could be
+modified, which simplifies bookkeeping, but the code to constantly refer
+back to the baseline gets complicated.
+
+Baseline-to-target has simpler code because the diff defines the action to
+take, but needs special handling for untracked and ignored files, if they
+need to be removed.
+
+The current checkout implementation is based on a baseline-to-target diff.
+
+
+Picking Actions
+===============
+
+The most interesting aspect of this is phase 2, picking the actions that
+should be taken.  There are a lot of corner cases, so it may be easier to
+start by looking at the rules for a simple 2-iterator diff:
+
+Key
+---
+- B1,B2,B3 - blobs with different SHAs,
+- Bi       - ignored blob (WD only)
+- T1,T2,T3 - trees with different SHAs,
+- Ti       - ignored tree (WD only)
+- x        - nothing
+
+Diff with 2 non-workdir iterators
+---------------------------------
+
+|    | Old | New |                                                            |
+|----|-----|-----|------------------------------------------------------------|
+|  0 |   x |   x | nothing                                                    |
+|  1 |   x |  B1 | added blob                                                 |
+|  2 |   x |  T1 | added tree                                                 |
+|  3 |  B1 |   x | removed blob                                               |
+|  4 |  B1 |  B1 | unmodified blob                                            |
+|  5 |  B1 |  B2 | modified blob                                              |
+|  6 |  B1 |  T1 | typechange blob -> tree                                    |
+|  7 |  T1 |   x | removed tree                                               |
+|  8 |  T1 |  B1 | typechange tree -> blob                                    |
+|  9 |  T1 |  T1 | unmodified tree                                            |
+| 10 |  T1 |  T2 | modified tree (implies modified/added/removed blob inside) |
+
+
+Now, let's make the "New" iterator into a working directory iterator, so
+we replace "added" items with either untracked or ignored, like this:
+
+Diff with non-work & workdir iterators
+--------------------------------------
+
+|    | Old | New |                                                            |
+|----|-----|-----|------------------------------------------------------------|
+|  0 |  x  | x   | nothing                                                    |
+|  1 |  x  | B1  | untracked blob                                             |
+|  2 |  x  | Bi  | ignored file                                               |
+|  3 |  x  | T1  | untracked tree                                             |
+|  4 |  x  | Ti  | ignored tree                                               |
+|  5 | B1  | x   | removed blob                                               |
+|  6 | B1  | B1  | unmodified blob                                            |
+|  7 | B1  | B2  | modified blob                                              |
+|  8 | B1  | T1  | typechange blob -> tree                                    |
+|  9 | B1  | Ti  | removed blob AND ignored tree as separate items            |
+| 10 | T1  | x   | removed tree                                               |
+| 11 | T1  | B1  | typechange tree -> blob                                    |
+| 12 | T1  | Bi  | removed tree AND ignored blob as separate items            |
+| 13 | T1  | T1  | unmodified tree                                            |
+| 14 | T1  | T2  | modified tree (implies modified/added/removed blob inside) |
+
+Note: if there is a corresponding entry in the old tree, then a working
+directory item won't be ignored (i.e. no Bi or Ti for tracked items).
+
+
+Now, expand this to three iterators: a baseline tree, a target tree, and
+an actual working directory tree:
+
+Checkout From 3 Iterators (2 not workdir, 1 workdir)
+----------------------------------------------------
+
+(base == old HEAD; target == what to checkout; actual == working dir)
+
+|     |base | target | actual/workdir |                                                                    |
+|-----|-----|------- |----------------|--------------------------------------------------------------------|
+|  0  |   x |      x |      x         | nothing                                                            |
+|  1  |   x |      x | B1/Bi/T1/Ti    | untracked/ignored blob/tree (SAFE)                                 |
+|  2+ |   x |     B1 |      x         | add blob (SAFE)                                                    |

+
+
+The number is followed by ' ' if no change is needed or '+' if the case
+needs to write to disk or '-' if something must be deleted and '*' if
+there should be a delete followed by an write.
+
+There are four tiers of safe cases:
+
+* SAFE         == completely safe to update
+* SAFE+MISSING == safe except the workdir is missing the expect content
+* MAYBE SAFE   == safe if workdir tree matches (or is missing) baseline
+                  content, which is unknown at this point
+* FORCEABLE == conflict unless FORCE is given
+* DIRTY     == no conflict but change is not applied unless FORCE
+
+Some slightly unusual circumstances:
+
+* 8 - parent dir is only deleted when file is, so parent will be left if
+    empty even though it would be deleted if the file were present
+* 11 - core git does not consider this a conflict but attempts to delete T1
+    and gives "unable to unlink file" error yet does not skip the rest
+    of the operation
+* 12 - without FORCE file is left deleted (i.e. not restored) so new wd is
+    dirty (and warning message "D file" is printed), with FORCE, file is
+    restored.
+* 24 - This should be considered MAYBE SAFE since effectively it is 7 and 8
+    combined, but core git considers this a conflict unless forced.
+* 26 - This combines two cases (1 & 25) (and also implied 8 for tree content)
+    which are ok on their own, but core git treat this as a conflict.
+    If not forced, this is a conflict.  If forced, this actually doesn't
+    have to write anything and leaves the new blob as an untracked file.
+* 32 - This is the only case where the baseline and target values match
+    and yet we will still write to the working directory.  In all other
+    cases, if baseline == target, we don't touch the workdir (it is
+    either already right or is "dirty").  However, since this case also
+    implies that a ?/B1/x case will exist as well, it can be skipped.
+
+Cases 3, 17, 24, 26, and 29 are all considered conflicts even though
+none of them will require making any updates to the working directory.

+Diff is broken into four phases:
+
+1. Building a list of things that have changed.  These changes are called
+   deltas (git_diff_delta objects) and are grouped into a git_diff_list.
+2. Applying file similarity measurement for rename and copy detection (and
+   to potentially split files that have changed radically).  This step is
+   optional.
+3. Computing the textual diff for each delta.  Not all deltas have a
+   meaningful textual diff.  For those that do, the textual diff can
+   either be generated on the fly and passed to output callbacks or can be
+   turned into a git_diff_patch object.
+4. Formatting the diff and/or patch into standard text formats (such as
+   patches, raw lists, etc).
+
+In the source code, step 1 is implemented in `src/diff.c`, step 2 in
+`src/diff_tform.c`, step 3 in `src/diff_patch.c`, and step 4 in
+`src/diff_print.c`.  Additionally, when it comes to accessing file
+content, everything goes through diff drivers that are implemented in
+`src/diff_driver.c`.
+
+External Objects
+----------------
+
+* `git_diff_options` represents user choices about how a diff should be
+  performed and is passed to most diff generating functions.
+* `git_diff_file` represents an item on one side of a possible delta
+* `git_diff_delta` represents a pair of items that have changed in some
+  way - it contains two `git_diff_file` plus a status and other stuff.
+* `git_diff_list` is a list of deltas along with information about how
+  those particular deltas were found.
+* `git_diff_patch` represents the actual diff between a pair of items.  In
+  some cases, a delta may not have a corresponding patch, if the objects
+  are binary, for example.  The content of a patch will be a set of hunks
+  and lines.
+* A `hunk` is range of lines described by a `git_diff_range` (i.e.  "lines
+  10-20 in the old file became lines 12-23 in the new").  It will have a
+  header that compactly represents that information, and it will have a
+  number of lines of context surrounding added and deleted lines.
+* A `line` is simple a line of data along with a `git_diff_line_t` value
+  that tells how the data should be interpreted (e.g. context or added).
+
+Internal Objects
+----------------
+
+* `git_diff_file_content` is an internal structure that represents the
+  data on one side of an item to be diffed; it is an augmented
+  `git_diff_file` with more flags and the actual file data.
+
+    * it is created from a repository plus a) a git_diff_file, b) a git_blob,
+   or c) raw data and size
+    * there are three main operations on git_diff_file_content:
+    
+        * _initialization_ sets up the data structure and does what it can up to,
+          but not including loading and looking at the actual data
+        * _loading_ loads the data, preprocesses it (i.e. applies filters) and
+          potentially analyzes it (to decide if binary)
+        * _free_ releases loaded data and frees any allocated memory
+
+* The internal structure of a `git_diff_patch` stores the actual diff
+  between a pair of `git_diff_file_content` items
+
+    * it may be "unset" if the items are not diffable
+    * "empty" if the items are the same
+    * otherwise it will consist of a set of hunks each of which covers some
+      number of lines of context, additions and deletions
+    * a patch is created from two git_diff_file_content items
+    * a patch is fully instantiated in three phases:
+    
+        * initial creation and initialization
+        * loading of data and preliminary data examination
+        * diffing of data and optional storage of diffs
+    * (TBD) if a patch is asked to store the diffs and the size of the diff
+      is significantly smaller than the raw data of the two sides, then the
+      patch may be flattened using a pool of string data
+
+* `git_diff_output` is an internal structure that represents an output
+  target for a `git_diff_patch`
+    * It consists of file, hunk, and line callbacks, plus a payload
+    * There is a standard flattened output that can be used for plain text output
+    * Typically we use a `git_xdiff_output` which drives the callbacks via the
+      xdiff code taken from core Git.
+
+* `git_diff_driver` is an internal structure that encapsulates the logic
+  for a given type of file
+    * a driver is looked up based on the name and mode of a file.
+    * the driver can then be used to:
+        * determine if a file is binary (by attributes, by git_diff_options
+          settings, or by examining the content)
+        * give you a function pointer that is used to evaluate function context
+          for hunk headers
+    * At some point, the logic for getting a filtered version of file content
+      or calculating the OID of a file may be moved into the driver.

+Error reporting in libgit2
+==========================
+
+Libgit2 tries to follow the POSIX style: functions return an `int` value
+with 0 (zero) indicating success and negative values indicating an error.
+There are specific negative error codes for each "expected failure"
+(e.g. `GIT_ENOTFOUND` for files that take a path which might be missing)
+and a generic error code (-1) for all critical or non-specific failures
+(e.g. running out of memory or system corruption).
+
+When a negative value is returned, an error message is also set.  The
+message can be accessed via the `giterr_last` function which will return a
+pointer to a `git_error` structure containing the error message text and
+the class of error (i.e. what part of the library generated the error).
+
+For instance: An object lookup by SHA prefix (`git_object_lookup_prefix`)
+has two expected failure cases: the SHA is not found at all which returns
+`GIT_ENOTFOUND` or the SHA prefix is ambiguous (i.e. two or more objects
+share the prefix) which returns `GIT_EAMBIGUOUS`.  There are any number of
+critical failures (such as a packfile being corrupted, a loose object
+having the wrong access permissions, etc.) all of which will return -1.
+When the object lookup is successful, it will return 0.
+
+If libgit2 was compiled with threads enabled (`-DTHREADSAFE=ON` when using
+CMake), then the error message will be kept in thread-local storage, so it
+will not be modified by other threads.  If threads are not enabled, then
+the error message is in global data.
+
+All of the error return codes, the `git_error` type, the error access
+functions, and the error classes are defined in `include/git2/errors.h`.
+See the documentation there for details on the APIs for accessing,
+clearing, and even setting error codes.
+
+When writing libgit2 code, please be smart and conservative when returning
+error codes.  Functions usually have a maximum of two or three "expected
+errors" and in most cases only one.  If you feel there are more possible
+expected error scenarios, then the API you are writing may be at too high
+a level for core libgit2.
+
+Example usage
+-------------
+
+When using libgit2, you will typically capture the return value from
+functions using an `int` variable and check to see if it is negative.
+When that happens, you can, if you wish, look at the specific value or
+look at the error message that was generated.
+
+~~~c
+{
+	git_repository *repo;
+	int error = git_repository_open(&repo, "path/to/repo");
+
+	if (error < 0) {
+		fprintf(stderr, "Could not open repository: %s\n", giterr_last()->message);
+		exit(1);
+	}
+
+	... use `repo` here ...
+
+	git_repository_free(repo); /* void function - no error return code */
+}
+~~~
+
+Some of the error return values do have meaning.  Optionally, you can look
+at the specific error values to decide what to do.
+
+~~~c
+{
+	git_repository *repo;
+	const char *path = "path/to/repo";
+	int error = git_repository_open(&repo, path);
+
+	if (error < 0) {
+		if (error == GIT_ENOTFOUND)
+			fprintf(stderr, "Could not find repository at path '%s'\n", path);
+		else
+			fprintf(stderr, "Unable to open repository: %s\n",
+				giterr_last()->message);
+		exit(1);
+	}
+
+	... happy ...
+}
+~~~
+
+Some of the higher-level language bindings may use a range of information
+from libgit2 to convert error return codes into exceptions, including the
+specific error return codes and even the class of error and the error
+message returned by `giterr_last`, but the full range of that logic is
+beyond the scope of this document.
+
+Example internal implementation
+-------------------------------
+
+Internally, libgit2 detects error scenarios, records error messages, and
+returns error values.  Errors from low-level functions are generally
+passed upwards (unless the higher level can either handle the error or
+wants to translate the error into something more meaningful).
+
+~~~c
+int git_repository_open(git_repository **repository, const char *path)
+{
+	/* perform some logic to open the repository */
+	if (p_exists(path) < 0) {
+		giterr_set(GITERR_REPOSITORY, "The path '%s' doesn't exist", path);
+		return GIT_ENOTFOUND;
+	}
+
+	...
+}
+~~~
+
+The public error API
+--------------------
+
+- `const git_error *giterr_last(void)`: The main function used to look up
+  the last error.  This may return NULL if no error has occurred.
+  Otherwise this should return a `git_error` object indicating the class
+  of error and the error message that was generated by the library.
+
+  The last error is stored in thread-local storage when libgit2 is
+  compiled with thread support, so you do not have to worry about another
+  thread overwriting the value.  When thread support is off, the last
+  error is a global value.
+
+  _Note_ There are some known bugs in the library where this may return
+  NULL even when an error code was generated.  Please report these as
+  bugs, but in the meantime, please code defensively and check for NULL
+  when calling this function.
+
+- `void geterr_clear(void)`: This function clears the last error.  The
+  library will call this when an error is generated by low level function
+  and the higher level function handles the error.
+
+  _Note_ There are some known bugs in the library where a low level
+  function's error message is not cleared by higher level code that
+  handles the error and returns zero.  Please report these as bugs, but in
+  the meantime, a zero return value from a libgit2 API does not guarantee
+  that `giterr_last()` will return NULL.
+
+- `void giterr_set_str(int error_class, const char *message)`: This
+  function can be used when writing a custom backend module to set the
+  libgit2 error message.  See the documentation on this function for its
+  use.  Normal usage of libgit2 will probably never need to call this API.
+
+- `void giterr_set_oom(void)`: This is a standard function for reporting
+  an out-of-memory error.  It is written in a manner that it doesn't have
+  to allocate any extra memory in order to record the error, so this is
+  the best way to report that scenario.
+
+Deviations from the standard
+----------------------------
+
+There are some public functions that do not return `int` values.  There
+are two primary cases:
+
+* `void` return values: If a function has a `void` return, then it will
+  never fail.  This primary will be used for object destructors.
+
+* `git_xyz *` return values: These are simple accessor functions where the
+  only meaningful error would typically be looking something up by index
+  and having the index be out of bounds.  In those cases, the function
+  will typically return NULL.
+
+* Boolean return values: There are some cases where a function cannot fail
+  and wants to return a boolean value.  In those cases, we try to return 1
+  for true and 0 for false.  These cases are rare and the return value for
+  the function should probably be an `unsigned int` to denote these cases.
+  If you find an exception, please open an issue and let's fix it.
+
+There are a few other exceptions to these rules here and there in the
+library, but those are extremely rare and should probably be converted
+over to other to more standard patterns for usage.  Feel free to open
+issues pointing these out.
+
+There are some known bugs in the library where some functions may return a
+negative value but not set an error message and some other functions may
+return zero (no error) and yet leave an error message set.  Please report
+these cases as issues and they will be fixed.  In the meanwhile, please
+code defensively, checking that the return value of `giterr_last` is not
+NULL before using it, and not relying on `giterr_last` to return NULL when
+a function returns 0 for success.
+
+The internal error API
+----------------------
+
+- `void giterr_set(int error_class, const char *fmt, ...)`: This is the
+  main internal function for setting an error.  It works like `printf` to
+  format the error message.  See the notes of `giterr_set_str` for a
+  general description of how error messages are stored (and also about
+  special handling for `error_class` of `GITERR_OS`).
+
+Writing error messages
+----------------------
+
+Here are some guidelines when writing error messages:
+
+- Use proper English, and an impersonal or past tenses: *The given path
+  does not exist*, *Failed to lookup object in ODB*
+
+- Use short, direct and objective messages. **One line, max**. libgit2 is
+  a low level library: think that all the messages reported will be thrown
+  as Ruby or Python exceptions. Think how long are common exception
+  messages in those languages.
+
+- **Do not add redundant information to the error message**, specially
+  information that can be inferred from the context.
+
+	E.g. in `git_repository_open`, do not report a message like "Failed to
+	open repository: path not found". Somebody is calling that
+	function. If it fails, they already know that the repository failed to
+	open!
+
+General guidelines for error reporting
+--------------------------------------
+
+- Libgit2 does not handle programming errors with these
+  functions. Programming errors are `assert`ed, and when their source is
+  internal, fixed as soon as possible. This is C, people.
+
+	Example of programming errors that would **not** be handled: passing
+    NULL to a function that expects a valid pointer; passing a `git_tree`
+    to a function that expects a `git_commit`. All these cases need to be
+    identified with `assert` and fixed asap.
+
+	Example of a runtime error: failing to parse a `git_tree` because it
+    contains invalid data. Failing to open a file because it doesn't exist
+    on disk. These errors are handled, a meaningful error message is set,
+    and an error code is returned.
+
+- In general, *do not* try to overwrite errors internally and *do*
+  propagate error codes from lower level functions to the higher level.
+  There are some cases where propagating an error code will be more
+  confusing rather than less, so there are some exceptions to this rule,
+  but the default behavior should be to simply clean up and pass the error
+  on up to the caller.
+
+    **WRONG**
+
+	~~~c
+	int git_commit_parent(...)
+	{
+		...
+
+		if (git_commit_lookup(parent, repo, parent_id) < 0) {
+			giterr_set(GITERR_COMMIT, "Overwrite lookup error message");
+			return -1; /* mask error code */
+		}
+
+		...
+	}
+	~~~
+
+	**RIGHT**
+
+	~~~c
+	int git_commit_parent(...)
+	{
+		...
+
+		error = git_commit_lookup(parent, repo, parent_id);
+		if (error < 0) {
+			/* cleanup intermediate objects if necessary */
+			/* leave error message and propagate error code */
+			return error;
+		}
+
+		...
+	}
+	~~~

+Creative Commons Legal Code
+
+CC0 1.0 Universal
+
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.

+libgit2 examples
+================
+
+These examples are a mixture of basic emulation of core Git command line
+functions and simple snippets demonstrating libgit2 API usage (for use
+with Docurium).  As a whole, they are not vetted carefully for bugs, error
+handling, and cross-platform compatibility in the same manner as the rest
+of the code in libgit2, so copy with caution.
+
+That being said, you are welcome to copy code from these examples as
+desired when using libgit2. They have been [released to the public domain][cc0],
+so there are no restrictions on their use.

+//
+// This file is an example of using that API in a real, compilable C file.
+// As the API is updated, this file will be updated to demonstrate the new

+// the relevant sections of the API docs in each section in this file.
+//

+// functions, not really the higher level porcelain stuff. For a primer on
+// Git Internals that you will need to know to work with Git at this level,

+  // For our first example, we will convert a 40 character hex value to the
+  // 20 byte raw SHA1 value.
+  printf("*Hex to Raw*\n");
+  char hex[] = "4a202b346bb0fb0db7eff3cffeb3c70babbd2045";

+  // key we're working with.
+  git_oid oid;
+  git_oid_fromstr(&oid, hex);
+
+  // Once we've converted the string into the oid value, we can get the raw
+  // value of the SHA by accessing `oid.id`
+
+  // Next we will convert the 20 byte raw SHA1 value to a human readable 40
+  // char hex value.
+  printf("\n*Raw to Hex*\n");

+  // If you have a oid, you can easily get the hex value of the SHA as well.
+  git_oid_fmt(out, &oid);
+  printf("SHA hex string: %s\n", out);
+
+  // ### Working with the Object Database
+
+  // **libgit2** provides [direct access][odb] to the object database.  The
+  // object database is where the actual objects are stored in Git. For
+  // working with raw objects, we'll need to get this structure from the

+  error = git_odb_read(&obj, odb, &oid);
+  check_error(error, "finding object in repository");
+
+  // A raw object only has three properties - the type (commit, blob, tree
+  // or tag), the size of the raw data and the raw, unparsed data itself.
+  // For a commit or tag, that raw data is human readable plain ASCII
+  // text. For a blob it is just file contents, so it could be text or
+  // binary data. For a tree it is a special binary format, so it's unlikely
+  // to be hugely helpful as a raw object.
+  data = (const unsigned char *)git_odb_object_data(obj);

+

+  // generated when the object was written to our database.
+  git_oid_fmt(out, &oid);
+  printf("Written Object: %s\n", out);
+
+  // ### Object Parsing
+
+  // libgit2 has methods to parse every object type in Git so you don't have
+  // to work directly with the raw data. This is much faster and simpler
+  // than trying to deal with the raw data yourself.
+
+  // #### Commit Parsing
+
+  // [Parsing commit objects][pco] is simple and gives you access to all the

+

+ * This can be awkward if the caller does not have easy access to the same
+ * allocation functions that libgit2 is using.  In those cases, libgit2

+ * A `git_buf` may also be used for the caller to pass in a reference to
+ * a block of memory they hold.  In this case, libgit2 will not resize or
+ * free the memory, but will read from it as needed.
+ *
+ * A `git_buf` is a public structure with three fields:
+ *
+ * - `ptr` points to the start of the allocated memory.  If it is NULL,
+ *   then the `git_buf` is considered empty and libgit2 will feel free
+ *   to overwrite it with new data.
+ *
+ * - `size` holds the size (in bytes) of the data that is actually used.
+ *
+ * - `asize` holds the known total amount of allocated memory if the `ptr`
+ *    was allocated by libgit2.  It may be larger than `size`.  If `ptr`
+ *    was not allocated by libgit2 and should not be resized and/or freed,
+ *    then `asize` will be set to zero.
+ *
+ * Some APIs may occasionally do something slightly unusual with a buffer,

+GIT_BEGIN_DECL
+
+/**
+ * Checkout behavior flags
+ *
+ * In libgit2, checkout is used to update the working directory and index
+ * to match a target tree.  Unlike git checkout, it does not move the HEAD
+ * commit for you - use `git_repository_set_head` or the like to do that.
+ *
+ * Checkout looks at (up to) four things: the "target" tree you want to
+ * check out, the "baseline" tree of what was checked out previously, the
+ * working directory for actual files, and the index for staged changes.
+ *
+ * You give checkout one of three strategies for update:
+ *
+ * - `GIT_CHECKOUT_NONE` is a dry-run strategy that checks for conflicts,
+ *   etc., but doesn't make any actual changes.
+ *
+ * - `GIT_CHECKOUT_FORCE` is at the opposite extreme, taking any action to
+ *   make the working directory match the target (including potentially
+ *   discarding modified files).
+ *
+ * - `GIT_CHECKOUT_SAFE` is between these two options, it will only make
+ *   modifications that will not lose changes.
+ *
+ *                         |  target == baseline   |  target != baseline  |
+ *    ---------------------|-----------------------|----------------------|
+ *     workdir == baseline |       no action       |  create, update, or  |
+ *                         |                       |     delete file      |
+ *    ---------------------|-----------------------|----------------------|
+ *     workdir exists and  |       no action       |   conflict (notify   |
+ *       is != baseline    | notify dirty MODIFIED | and cancel checkout) |
+ *    ---------------------|-----------------------|----------------------|
+ *      workdir missing,   | notify dirty DELETED  |     create file      |
+ *      baseline present   |                       |                      |
+ *    ---------------------|-----------------------|----------------------|
+ *
+ * To emulate `git checkout`, use `GIT_CHECKOUT_SAFE` with a checkout
+ * notification callback (see below) that displays information about dirty
+ * files.  The default behavior will cancel checkout on conflicts.
+ *
+ * To emulate `git checkout-index`, use `GIT_CHECKOUT_SAFE` with a
+ * notification callback that cancels the operation if a dirty-but-existing
+ * file is found in the working directory.  This core git command isn't
+ * quite "force" but is sensitive about some types of changes.
+ *
+ * To emulate `git checkout -f`, use `GIT_CHECKOUT_FORCE`.
+ *
+ *
+ * There are some additional flags to modified the behavior of checkout:
+ *
+ * - GIT_CHECKOUT_ALLOW_CONFLICTS makes SAFE mode apply safe file updates
+ *   even if there are conflicts (instead of cancelling the checkout).
+ *
+ * - GIT_CHECKOUT_REMOVE_UNTRACKED means remove untracked files (i.e. not
+ *   in target, baseline, or index, and not ignored) from the working dir.
+ *
+ * - GIT_CHECKOUT_REMOVE_IGNORED means remove ignored files (that are also
+ *   untracked) from the working directory as well.
+ *
+ * - GIT_CHECKOUT_UPDATE_ONLY means to only update the content of files that
+ *   already exist.  Files will not be created nor deleted.  This just skips
+ *   applying adds, deletes, and typechanges.
+ *
+ * - GIT_CHECKOUT_DONT_UPDATE_INDEX prevents checkout from writing the
+ *   updated files' information to the index.
+ *
+ * - Normally, checkout will reload the index and git attributes from disk
+ *   before any operations.  GIT_CHECKOUT_NO_REFRESH prevents this reload.
+ *
+ * - Unmerged index entries are conflicts.  GIT_CHECKOUT_SKIP_UNMERGED skips
+ *   files with unmerged index entries instead.  GIT_CHECKOUT_USE_OURS and
+ *   GIT_CHECKOUT_USE_THEIRS to proceed with the checkout using either the
+ *   stage 2 ("ours") or stage 3 ("theirs") version of files in the index.
+ *
+ * - GIT_CHECKOUT_DONT_OVERWRITE_IGNORED prevents ignored files from being
+ *   overwritten.  Normally, files that are ignored in the working directory
+ *   are not considered "precious" and may be overwritten if the checkout
+ *   target contains that file.
+ *
+ * - GIT_CHECKOUT_DONT_REMOVE_EXISTING prevents checkout from removing
+ *   files or folders that fold to the same name on case insensitive
+ *   filesystems.  This can cause files to retain their existing names
+ *   and write through existing symbolic links.

+/**
+ * @file git2/diff.h
+ * @brief Git tree and file differencing routines.
+ *
+ * Overview
+ * --------
+ *
+ * Calculating diffs is generally done in two phases: building a list of
+ * diffs then traversing it.  This makes is easier to share logic across
+ * the various types of diffs (tree vs tree, workdir vs index, etc.), and
+ * also allows you to insert optional diff post-processing phases,
+ * such as rename detection, in between the steps.  When you are done with
+ * a diff object, it must be freed.
+ *
+ * Terminology
+ * -----------
+ *
+ * To understand the diff APIs, you should know the following terms:
+ *
+ * - A `diff` represents the cumulative list of differences between two
+ *   snapshots of a repository (possibly filtered by a set of file name
+ *   patterns).  This is the `git_diff` object.
+ *
+ * - A `delta` is a file pair with an old and new revision.  The old version
+ *   may be absent if the file was just created and the new version may be
+ *   absent if the file was deleted.  A diff is mostly just a list of deltas.
+ *
+ * - A `binary` file / delta is a file (or pair) for which no text diffs
+ *   should be generated.  A diff can contain delta entries that are
+ *   binary, but no diff content will be output for those files.  There is
+ *   a base heuristic for binary detection and you can further tune the
+ *   behavior with git attributes or diff flags and option settings.
+ *
+ * - A `hunk` is a span of modified lines in a delta along with some stable
+ *   surrounding context.  You can configure the amount of context and other
+ *   properties of how hunks are generated.  Each hunk also comes with a
+ *   header that described where it starts and ends in both the old and new
+ *   versions in the delta.
+ *
+ * - A `line` is a range of characters inside a hunk.  It could be a context
+ *   line (i.e. in both old and new versions), an added line (i.e. only in
+ *   the new version), or a removed line (i.e. only in the old version).
+ *   Unfortunately, we don't know anything about the encoding of data in the
+ *   file being diffed, so we cannot tell you much about the line content.
+ *   Line data will not be NUL-byte terminated, however, because it will be
+ *   just a span of bytes inside the larger file.

+ * Packing objects
+ * ---------------
+ *
+ * Creation of packfiles requires two steps:
+ *
+ * - First, insert all the objects you want to put into the packfile
+ *   using `git_packbuilder_insert` and `git_packbuilder_insert_tree`.
+ *   It's important to add the objects in recency order ("in the order
+ *   that they are 'reachable' from head").
+ *
+ *   "ANY order will give you a working pack, ... [but it is] the thing
+ *   that gives packs good locality. It keeps the objects close to the
+ *   head (whether they are old or new, but they are _reachable_ from the
+ *   head) at the head of the pack. So packs actually have absolutely
+ *   _wonderful_ IO patterns." - Linus Torvalds
+ *   git.git/Documentation/technical/pack-heuristics.txt
+ *
+ * - Second, use `git_packbuilder_write` or `git_packbuilder_foreach` to
+ *   write the resulting packfile.
+ *
+ *   libgit2 will take care of the delta ordering and generation.
+ *   `git_packbuilder_set_threads` can be used to adjust the number of
+ *   threads used for the process.
+ *
+ * See tests/pack/packbuilder.c for an example.

+ * * NO_REINIT - Return an GIT_EEXISTS error if the repo_path appears to
+ *        already be an git repository.
+ * * NO_DOTGIT_DIR - Normally a "/.git/" will be appended to the repo
+ *        path for non-bare repos (if it is not already there), but
+ *        passing this flag prevents that behavior.
+ * * MKDIR  - Make the repo_path (and workdir_path) as needed.  Init is
+ *        always willing to create the ".git" directory even without this
+ *        flag.  This flag tells init to create the trailing component of
+ *        the repo and workdir paths as needed.
+ * * MKPATH - Recursively make all components of the repo and workdir
+ *        paths as necessary.
+ * * EXTERNAL_TEMPLATE - libgit2 normally uses internal templates to
+ *        initialize a new repo.  This flags enables external templates,
+ *        looking the "template_path" from the options if set, or the
+ *        `init.templatedir` global config if not, or falling back on
+ *        "/usr/share/git-core/templates" if it exists.
+ * * GIT_REPOSITORY_INIT_RELATIVE_GITLINK - If an alternate workdir is
+ *        specified, use relative paths for the gitdir and core.worktree.

+ * - GIT_STATUS_OPT_INCLUDE_IGNORED says that ignored files get callbacks.

+ * - GIT_STATUS_OPT_INCLUDE_UNMODIFIED indicates that callback should be
+ *   made even on unmodified files.
+ * - GIT_STATUS_OPT_EXCLUDE_SUBMODULES indicates that submodules should be
+ *   skipped.  This only applies if there are no pending typechanges to
+ *   the submodule (either from or to another type).
+ * - GIT_STATUS_OPT_RECURSE_UNTRACKED_DIRS indicates that all files in
+ *   untracked directories should be included.  Normally if an entire
+ *   directory is new, then just the top-level directory is included (with
+ *   a trailing slash on the entry name).  This flag says to include all
+ *   of the individual files in the directory instead.
+ * - GIT_STATUS_OPT_DISABLE_PATHSPEC_MATCH indicates that the given path
+ *   should be treated as a literal path, and not as a pathspec pattern.
+ * - GIT_STATUS_OPT_RECURSE_IGNORED_DIRS indicates that the contents of
+ *   ignored directories should be included in the status.  This is like
+ *   doing `git ls-files -o -i --exclude-standard` with core git.
+ * - GIT_STATUS_OPT_RENAMES_HEAD_TO_INDEX indicates that rename detection
+ *   should be processed between the head and the index and enables
+ *   the GIT_STATUS_INDEX_RENAMED as a possible status flag.
+ * - GIT_STATUS_OPT_RENAMES_INDEX_TO_WORKDIR indicates that rename
+ *   detection should be run between the index and the working directory
+ *   and enabled GIT_STATUS_WT_RENAMED as a possible status flag.
+ * - GIT_STATUS_OPT_SORT_CASE_SENSITIVELY overrides the native case
+ *   sensitivity for the file system and forces the output to be in
+ *   case-sensitive order
+ * - GIT_STATUS_OPT_SORT_CASE_INSENSITIVELY overrides the native case
+ *   sensitivity for the file system and forces the output to be in
+ *   case-insensitive order
+ * - GIT_STATUS_OPT_RENAMES_FROM_REWRITES indicates that rename detection
+ *   should include rewritten files
+ * - GIT_STATUS_OPT_NO_REFRESH bypasses the default status behavior of
+ *   doing a "soft" index reload (i.e. reloading the index data if the
+ *   file on disk has been modified outside libgit2).
+ * - GIT_STATUS_OPT_UPDATE_INDEX tells libgit2 to refresh the stat cache
+ *   in the index for files that are unchanged but have out of date stat
+ *   information in the index.  It will result in less work being done on
+ *   subsequent calls to get status.  This is mutually exclusive with the
+ *   NO_REFRESH option.
+ *
+ * Calling `git_status_foreach()` is like calling the extended version
+ * with: GIT_STATUS_OPT_INCLUDE_IGNORED, GIT_STATUS_OPT_INCLUDE_UNTRACKED,
+ * and GIT_STATUS_OPT_RECURSE_UNTRACKED_DIRS.  Those options are bundled

+ * Patterns have the following format:

+ * - A blank line matches no files, so it can serve as a separator for
+ *   readability.
+ *
+ * - A line starting with # serves as a comment.
+ *
+ * - An optional prefix ! which negates the pattern; any matching file
+ *   excluded by a previous pattern will become included again. If a negated
+ *   pattern matches, this will override lower precedence patterns sources.
+ *
+ * - If the pattern ends with a slash, it is removed for the purpose of the
+ *   following description, but it would only find a match with a directory. In
+ *   other words, foo/ will match a directory foo and paths underneath it, but
+ *   will not match a regular file or a symbolic link foo (this is consistent
+ *   with the way how pathspec works in general in git).
+ *
+ * - If the pattern does not contain a slash /, git treats it as a shell glob
+ *   pattern and checks for a match against the pathname without leading
+ *   directories.
+ *
+ * - Otherwise, git treats the pattern as a shell glob suitable for consumption
+ *   by fnmatch(3) with the FNM_PATHNAME flag: wildcards in the pattern will
+ *   not match a / in the pathname. For example, "Documentation/\*.html" matches
+ *   "Documentation/git.html" but not "Documentation/ppc/ppc.html". A leading
+ *   slash matches the beginning of the pathname; for example, "/\*.c" matches
+ *   "cat-file.c" but not "mozilla-sha1/sha1.c".

+    * Minor code clean up; no actual effect.
+
+  2011-09-16 (0.2.6):
+
+	* The capacity is a power of 2. This seems to dramatically improve the
+	  speed for simple keys. Thank Zilong Tan for the suggestion. Reference:
+
+	   - http://code.google.com/p/ulib/
+	   - http://nothings.org/computer/judy/
+
+	* Allow to optionally use linear probing which usually has better
+	  performance for random input. Double hashing is still the default as it
+	  is more robust to certain non-random input.
+
+	* Added Wang's integer hash function (not used by default). This hash
+	  function is more robust to certain non-random input.
+
+  2011-02-14 (0.2.5):
+
+    * Allow to declare global functions.
+
+  2009-09-26 (0.2.4):
+
+    * Improve portability
+
+  2008-09-19 (0.2.3):
+
+	* Corrected the example
+	* Improved interfaces
+
+  2008-09-11 (0.2.2):
+
+	* Improved speed a little in kh_put()
+
+  2008-09-10 (0.2.1):
+
+	* Added kh_clear()
+	* Fixed a compiling error
+
+  2008-09-02 (0.2.0):
+
+	* Changed to token concatenation which increases flexibility.
+
+  2008-08-31 (0.1.2):
+
+	* Fixed a bug in kh_get(), which has not been tested previously.
+
+  2008-08-31 (0.1.1):
+

+/**
+ * The wonderful tale of a Packed Object lookup query
+ * ===================================================
+ *	A riveting and epic story of epicness and ASCII
+ *			art, presented by yours truly,
+ *				Sir Vicent of Marti
+ *
+ *
+ *	Chapter 1: Once upon a time...
+ *	Initialization of the Pack Backend
+ *	--------------------------------------------------
+ *
+ *	# git_odb_backend_pack
+ *	| Creates the pack backend structure, initializes the
+ *	| callback pointers to our default read() and exist() methods,
+ *	| and tries to preload all the known packfiles in the ODB.
+ * |
+ *	|-# packfile_load_all
+ *	 | Tries to find the `pack` folder, if it exists. ODBs without
+ *	 | a pack folder are ignored altogether. If there's a `pack` folder
+ *	 | we run a `dirent` callback through every file in the pack folder
+ *	 | to find our packfiles. The packfiles are then sorted according
+ *	 | to a sorting callback.
+ * 	 |
+ *	 |-# packfile_load__cb
+ *	 | | This callback is called from `dirent` with every single file
+ *	 | | inside the pack folder. We find the packs by actually locating
+ *	 | | their index (ends in ".idx"). From that index, we verify that
+ *	 | | the corresponding packfile exists and is valid, and if so, we
+ *	| | add it to the pack list.
+ *	 | |
+ *	 | |-# packfile_check
+ *	 |		Make sure that there's a packfile to back this index, and store
+ *	 |		some very basic information regarding the packfile itself,
+ *	 |		such as the full path, the size, and the modification time.
+ *	 |		We don't actually open the packfile to check for internal consistency.
+ *	|
+ *	|-# packfile_sort__cb
+ *		Sort all the preloaded packs according to some specific criteria:
+ *		we prioritize the "newer" packs because it's more likely they
+ *		contain the objects we are looking for, and we prioritize local
+ *		packs over remote ones.
+ *
+ *
+ *
+ *	Chapter 2: To be, or not to be...
+ *	A standard packed `exist` query for an OID
+ *	--------------------------------------------------
+ *
+ * # pack_backend__exists
+ * | Check if the given SHA1 oid exists in any of the packs
+ * | that have been loaded for our ODB.
+ * |
+ * |-# pack_entry_find
+ *	| Iterate through all the packs that have been preloaded
+ *	| (starting by the pack where the latest object was found)
+ *	| to try to find the OID in one of them.
+ *	|
+ *	|-# pack_entry_find1
+ *		| Check the index of an individual pack to see if the SHA1
+ *		| OID can be found. If we can find the offset to that SHA1
+ *		| inside of the index, that means the object is contained
+ *		| inside of the packfile and we can stop searching.
+ *		| Before returning, we verify that the packfile behing the
+ *		| index we are searching still exists on disk.
+ *		|
+ *		|-# pack_entry_find_offset
+ *		| | Mmap the actual index file to disk if it hasn't been opened
+ *		| | yet, and run a binary search through it to find the OID.
+ *		| | See <http://book.git-scm.com/7_the_packfile.html> for specifics
+ *		| | on the Packfile Index format and how do we find entries in it.
+ *		| |
+ *		| |-# pack_index_open
+ *		|	| Guess the name of the index based on the full path to the
+ *		|	| packfile, open it and verify its contents. Only if the index
+ *		|	| has not been opened already.
+ *		|	|
+ *		|	|-# pack_index_check
+ *		|		Mmap the index file and do a quick run through the header
+ *		|		to guess the index version (right now we support v1 and v2),
+ *		|		and to verify that the size of the index makes sense.
+ *		|
+ *		|-# packfile_open
+ *			See `packfile_open` in Chapter 3
+ *
+ *
+ *
+ *	Chapter 3: The neverending story...
+ *	A standard packed `lookup` query for an OID

+ * What wizardry is this?
+ *
+ * This is just a memory-optimized trie: basically a very fancy
+ * 16-ary tree, which is used to store the prefixes of the OID
+ * strings.
+ *
+ * Read more: http://en.wikipedia.org/wiki/Trie
+ *
+ * Magic that happens in this method:
+ *
+ *	- Each node in the trie is an union, so it can work both as
+ *	a normal node, or as a leaf.
+ *
+ *	- Each normal node points to 16 children (one for each possible
+ *	character in the oid). This is *not* stored in an array of
+ *	pointers, because in a 64-bit arch this would be sucking
+ *	16*sizeof(void*) = 128 bytes of memory per node, which is
+ *	insane. What we do is store Node Indexes, and use these indexes
+ *	to look up each node in the om->index array. These indexes are
+ *	signed shorts, so this limits the amount of unique OIDs that
+ *	fit in the structure to about 20000 (assuming a more or less uniform
+ *	distribution).
+ *
+ *	- All the nodes in om->index array are stored contiguously in
+ *	memory, and each of them is 32 bytes, so we fit 2x nodes per
+ *	cache line. Convenient for speed.
+ *
+ *	- To differentiate the leafs from the normal nodes, we store all
+ *	the indexes towards a leaf as a negative index (indexes to normal
+ *	nodes are positives). When we find that one of the children for
+ *	a node has a negative value, that means it's going to be a leaf.
+ *	This reduces the amount of indexes we have by two, but also reduces
+ *	the size of each node by 1-4 bytes (the amount we would need to
+ *	add a `is_leaf` field): this is good because it allows the nodes
+ *	to fit cleanly in cache lines.
+ *
+ *	- Once we reach an empty children, instead of continuing to insert
+ *	new nodes for each remaining character of the OID, we store a pointer
+ *	to the tail in the leaf; if the leaf is reached again, we turn it
+ *	into a normal node and use the tail to create a new leaf.
+ *
+ *	This is a pretty good balance between performance and memory usage.

+ * Conventional binary search loop looks like this:
+ *
+ *	unsigned lo, hi;
+ *		do {
+ *				unsigned mi = (lo + hi) / 2;
+ *				int cmp = "entry pointed at by mi" minus "target";
+ *				if (!cmp)
+ *						return (mi is the wanted one)
+ *				if (cmp > 0)
+ *						hi = mi; "mi is larger than target"
+ *				else
+ *						lo = mi+1; "mi is smaller than target"
+ *		} while (lo < hi);
+ *
+ * The invariants are:
+ *
+ * - When entering the loop, lo points at a slot that is never
+ *	above the target (it could be at the target), hi points at a
+ *	slot that is guaranteed to be above the target (it can never
+ *	be at the target).
+ *
+ * - We find a point 'mi' between lo and hi (mi could be the same
+ *	as lo, but never can be as same as hi), and check if it hits
+ *	the target. There are three cases:
+ *
+ *	- if it is a hit, we are happy.
+ *
+ *	- if it is strictly higher than the target, we set it to hi,
+ *		and repeat the search.
+ *
+ *	- if it is strictly lower than the target, we update lo to
+ *		one slot after it, because we allow lo to be at the target.
+ *
+ *	If the loop exits, there is no matching entry.
+ *
+ * When choosing 'mi', we do not have to take the "middle" but
+ * anywhere in between lo and hi, as long as lo <= mi < hi is
+ * satisfied. When we somehow know that the distance between the
+ * target and lo is much shorter than the target and hi, we could
+ * pick mi that is much closer to lo than the midway.
+ *
+ * Now, we can take advantage of the fact that SHA-1 is a good hash
+ * function, and as long as there are enough entries in the table, we
+ * can expect uniform distribution. An entry that begins with for
+ * example "deadbeef..." is much likely to appear much later than in
+ * the midway of the table. It can reasonably be expected to be near
+ * 87% (222/256) from the top of the table.
+ *
+ * However, we do not want to pick "mi" too precisely. If the entry at
+ * the 87% in the above example turns out to be higher than the target
+ * we are looking for, we would end up narrowing the search space down
+ * only by 13%, instead of 50% we would get if we did a simple binary
+ * search. So we would want to hedge our bets by being less aggressive.
+ *
+ * The table at "table" holds at least "nr" entries of "elem_size"
+ * bytes each. Each entry has the SHA-1 key at "key_offset". The
+ * table is sorted by the SHA-1 key of the entries. The caller wants
+ * to find the entry with "key", and knows that the entry at "lo" is
+ * not higher than the entry it is looking for, and that the entry at
+ * "hi" is higher than the entry it is looking for.

+/**
+ * Description of submodule
+ *
+ * This record describes a submodule found in a repository.  There should be
+ * an entry for every submodule found in the HEAD and index, and for every
+ * submodule described in .gitmodules.  The fields are as follows:
+ *
+ * - `rc` tracks the refcount of how many hash table entries in the
+ *   git_submodule_cache there are for this submodule.  It only comes into
+ *   play if the name and path of the submodule differ.
+ *
+ * - `name` is the name of the submodule from .gitmodules.
+ * - `path` is the path to the submodule from the repo root.  It is almost
+ *    always the same as `name`.
+ * - `url` is the url for the submodule.
+ * - `update` is a git_submodule_update_t value - see gitmodules(5) update.
+ * - `update_default` is the update value from the config
+ * - `ignore` is a git_submodule_ignore_t value - see gitmodules(5) ignore.
+ * - `ignore_default` is the ignore value from the config
+ * - `fetch_recurse` is a git_submodule_recurse_t value - see gitmodules(5)
+ *    fetchRecurseSubmodules.
+ * - `fetch_recurse_default` is the recurse value from the config
+ *
+ * - `repo` is the parent repository that contains this submodule.
+ * - `flags` after for internal use, tracking where this submodule has been
+ *   found (head, index, config, workdir) and known status info, etc.
+ * - `head_oid` is the SHA1 for the submodule path in the repo HEAD.
+ * - `index_oid` is the SHA1 for the submodule recorded in the index.
+ * - `wd_oid` is the SHA1 for the HEAD of the checked out submodule.
+ *
+ * If the submodule has been added to .gitmodules but not yet git added,
+ * then the `index_oid` will be zero but still marked valid.  If the
+ * submodule has been deleted, but the delete has not been committed yet,
+ * then the `index_oid` will be set, but the `url` will be NULL.

+Writing Clar tests for libgit2
+==============================
+
+For information on the Clar testing framework and a detailed introduction
+please visit:
+
+https://github.com/vmg/clar
+
+
+* Write your modules and tests. Use good, meaningful names.
+
+* Make sure you actually build the tests by setting:
+
+        cmake -DBUILD_CLAR=ON build/
+
+* Test:
+
+        ./build/libgit2_clar
+
+* Make sure everything is fine.
+
+* Send your pull request. That's it.

+# Test file from gitattributes(5) example:
+
+If you have these three gitattributes file:
+
+   (in $GIT_DIR/info/attributes)
+
+	a*      foo !bar -baz
+
+	(in .gitattributes)
+	abc     foo bar baz
+
+	(in t/.gitattributes)
+	ab*     merge=filfre
+	abc     -foo -bar
+	*.c     frotz
+
+the attributes given to path t/abc are computed as follows:
+
+1. By examining t/.gitattributes (which is in the same directory as the path
+   in question), git finds that the first line matches. merge attribute is
+   set. It also finds that the second line matches, and attributes foo and
+   bar are unset.
+2. Then it examines .gitattributes (which is in the parent directory), and
+   finds that the first line matches, but t/.gitattributes file already
+   decided how merge, foo and bar attributes should be given to this path,
+   so it leaves foo and bar unset. Attribute baz is set.
+3. Finally it examines $GIT_DIR/info/attributes. This file is used to
+   override the in-tree settings. The first line is a match, and foo is set,
+   bar is reverted to unspecified state, and baz is unset.
+
+As the result, the attributes assignment to t/abc becomes:
+
+	foo     set to true
+	bar     unspecified
+	baz     set to false
+	merge   set to string value "filfre"
+	frotz   unspecified

+Git is fast. With Git, nearly all operations are performed locally, giving
+it an huge speed advantage on centralized systems that constantly have to
+communicate with a server somewh3r3.
+
+For testing, large AWS instances were set up in the same availability
+zone. Git and SVN were installed on both machines, the Ruby repository was
+copied to both Git and SVN servers, and common operations were performed on
+both.
+
+In some cases the commands don't match up exactly. Here, matching on the
+lowest common denominator was attempted. For example, the 'commit' tests
+also include the time to push for Git, though most of the time you would not
+actually be pushing to the server immediately after a commit where the two
+commands cannot be separated in SVN.
+
+Note that this is the best case scenario for SVN - a server with no load
+with an 80MB/s bandwidth connection to the client machine. Nearly all of
+these times would be even worse for SVN if that connection was slower, while
+many of the Git times would not be affected.
+
+Clearly, in many of these common version control operations, Git is one or
+two orders of magnitude faster than SVN, even under ideal conditions for
+SVN.
+
+Let's see how common operations stack up against Subversion, a common
+centralized version control system that is similar to CVS or
+Perforce. Smaller is faster.

+One place where Git is slower is in the initial clone operation. Here, Git

+
+It's also interesting to note that the size of the data on the client side
+is very similar even though Git also has every version of every file for the
+entire history of the project. This illustrates how efficient it is at
+compressing and storing data on the client side.

+
+Git allows and encourages you to have multiple local branches that can be
+entirely independent of each other. The creation, merging, and deletion of
+those lines of development takes seconds.
+
+This means that you can do things like:
+
+Role-Bas3d Codelin3s. Have a branch that always contains only what goes to
+production, another that you merge work into for testing, and several
+smaller ones for day to day work.
+
+Feature Based Workflow. Create new branches for each new feature you're
+working on so you can seamlessly switch back and forth between them, then
+delete each branch when that feature gets merged into your main line.
+
+Disposable Experimentation. Create a branch to experiment in, realize it's
+not going to work, and just delete it - abandoning the work—with nobody else
+ever seeing it (even if you've pushed other branches in the meantime).
+
+Notably, when you push to a remote repository, you do not have to push all
+share it with others.
+
+Git allows and encourages you to have multiple local branches that can be
+entirely independent of each other. The creation, merging, and deletion of
+those lines of development takes seconds.
+
+There are ways to accomplish some of this with other systems, but the work
+involved is much more difficult and error-prone. Git makes this process
+incredibly easy and it changes the way most developers work when they learn
+it.!

+BEEF SOUP.
+
+Take the hind shin of beef, cut off all the flesh off the leg-bone,
+which must be taken away entirely, or the soup will be greasy. Wash the
+meat clean and lay it in a pot, sprinkle over it one small
+table-spoonful of pounded black pepper, and two of salt; three onions
+the size of a hen's egg, cut small, six small carrots scraped and cut
+up, two small turnips pared and cut into dice; pour on three quarts of
+water, cover the pot close, and keep it gently and steadily boiling five
+hours, which will leave about three pints of clear soup; do not let the
+pot boil over, but take off the scum carefully, as it rises. When it has
+boiled four hours, put in a small bundle of thyme and parsley, and a
+pint of celery cut small, or a tea-spoonful of celery seed pounded.
+These latter ingredients would lose their delicate flavour if boiled too
+much. Just before you take it up, brown it in the following manner: put
+a small table-spoonful of nice brown sugar into an iron skillet, set it
+on the fire and stir it till it melts and looks very dark, pour into it
+a ladle full of the soup, a little at a time; stirring it all the while.
+Strain this browning and mix it well with the soup; take out the bundle
+of thyme and parsley, put the nicest pieces of meat in your tureen, and
+pour on the soup and vegetables; put in some toasted bread cut in dice,
+and serve it up.

+SOUP WITH BOUILLI.
+
+Take the nicest part of the thick brisket of beef, about eight pounds,
+put it into a pot with every thing directed for the other soup; make it
+exactly in the same way, only put it on an hour sooner, that you may
+have time to prepare the bouilli; after it has boiled five hours, take
+out the beef, cover up the soup and set it near the fire that it may
+keep hot. Take the skin off the beef, have the yelk of an egg well
+beaten, dip a feather in it and wash the top of your beef, sprinkle over
+it the crumb of stale bread finely grated, put it in a Dutch oven
+previously heated, put the top on with coals enough to brown, but not
+burn the beef; let it stand nearly an hour, and prepare your gravy
+thus:--Take a sufficient quantity of soup and the vegetables boiled in
+it; add to it a table-spoonful of red wine, and two of mushroom catsup,
+thicken with a little bit of butter and a little brown flour; make it
+very hot, pour it in your dish, and put the beef on it. Garnish it with
+green pickle, cut in thin slices, serve up the soup in a tureen with
+bits of toasted bread.

+GRAVY SOUP.
+
+Get eight pounds of coarse lean beef--wash it clean and lay it in your
+pot, put in the same ingredients as for the shin soup, with the same
+quantity of water, and follow the process directed for that. Strain the
+soup through a sieve, and serve it up clear, with nothing more than
+toasted bread in it; two table-spoonsful of mushroom catsup will add a
+fine flavour to the soup.

+OYSTER SOUP.
+
+Wash and drain two quarts of oysters, put them on with three quarts of
+water, three onions chopped up, two or three slices of lean ham, pepper
+and salt; boil it till reduced one-half, strain it through a sieve,
+return the liquid into the pot, put in one quart of fresh oysters, boil
+it till they are sufficiently done, and thicken the soup with four
+spoonsful of flour, two gills of rich cream, and the yelks of six new
+laid eggs beaten well; boil it a few minutes after the thickening is put
+in. Take care that it does not curdle, and that the flour is not in
+lumps; serve it up with the last oysters that were put in. If the
+flavour of thyme be agreeable, you may put in a little, but take care
+that it does not boil in it long enough to discolour the soup.

+VEAL SOUP.
+
+Put into a pot three quarts of water, three onions cut small, one
+spoonful of black pepper pounded, and two of salt, with two or three
+slices of lean ham; let it boil steadily two hours; skim it
+occasionally, then put into it a shin of veal, let it boil two hours
+longer; take out the slices of ham, and skim off the grease if any
+should rise, take a gill of good cream, mix with it two table-spoonsful
+of flour very nicely, and the yelks of two eggs beaten well, strain this
+mixture, and add some chopped parsley; pour some soup on by degrees,
+stir it well, and pour it into the pot, continuing to stir until it has
+boiled two or three minutes to take off the raw taste of the eggs. If
+the cream be not perfectly sweet, and the eggs quite new, the thickening
+will curdle in the soup. For a change you may put a dozen ripe tomatos
+in, first taking off their skins, by letting them stand a few minutes in
+hot water, when they may be easily peeled. When made in this way you
+must thicken it with the flour only. Any part of the veal may be used,
+but the shin or knuckle is the nicest.

+The Song of Seven Cities
+------------------------
+
+I WAS Lord of Cities very sumptuously builded.
+Seven roaring Cities paid me tribute from afar.
+Ivory their outposts were--the guardrooms of them gilded,
+And garrisoned with Amazons invincible in war.
+
+All the world went softly when it walked before my Cities--
+Neither King nor Army vexed my peoples at their toil,
+Never horse nor chariot irked or overbore my Cities,
+Never Mob nor Ruler questioned whence they drew their spoil.
+
+Banded, mailed and arrogant from sunrise unto sunset;
+Singing while they sacked it, they possessed the land at large.
+Yet when men would rob them, they resisted, they made onset
+And pierced the smoke of battle with a thousand-sabred charge.
+
+So they warred and trafficked only yesterday, my Cities.
+To-day there is no mark or mound of where my Cities stood.
+For the River rose at midnight and it washed away my Cities.
+They are evened with Atlantis and the towns before the Flood.
+
+Rain on rain-gorged channels raised the water-levels round them,
+Freshet backed on freshet swelled and swept their world from sight,
+Till the emboldened floods linked arms and, flashing forward, drowned them--
+Drowned my Seven Cities and their peoples in one night!
+
+Low among the alders lie their derelict foundations,
+The beams wherein they trusted and the plinths whereon they built--
+My rulers and their treasure and their unborn populations,
+Dead, destroyed, aborted, and defiled with mud and silt!
+
+The Daughters of the Palace whom they cherished in my Cities,
+My silver-tongued Princesses, and the promise of their May--
+Their bridegrooms of the June-tide--all have perished in my Cities,
+With the harsh envenomed virgins that can neither love nor play.
+
+I was Lord of Cities--I will build anew my Cities,
+Seven, set on rocks, above the wrath of any flood.
+Nor will I rest from search till I have filled anew my Cities
+With peoples undefeated of the dark, enduring blood.
+
+To the sound of trumpets shall their seed restore my Cities
+Wealthy and well-weaponed, that once more may I behold
+All the world go softly when it walks before my Cities,
+And the horses and the chariots fleeing from them as of old!
+

+Untimely
+========
+
+Nothing in life has been made by man for man's using
+But it was shown long since to man in ages
+Lost as the name of the maker of it,
+Who received oppression and shame for his wages--
+Hate, avoidance, and scorn in his daily dealings--
+Until he perished, wholly confounded
+
+More to be pitied than he are the wise
+Souls which foresaw the evil of loosing
+Knowledge or Art before time, and aborted
+Noble devices and deep-wrought healings,
+Lest offense should arise.
+
+Heaven delivers on earth the Hour that cannot be
+  thwarted,
+Neither advanced, at the price of a world nor a soul,
+  and its Prophet
+Comes through the blood of the vanguards who
+  dreamed--too soon--it had sounded.
+

+This is a test repo for libgit2 where tree entries have type changes
+
+Types
+-----
+
+The key types that could be found in tree entries are:
+
+1. GIT_FILEMODE_NEW             = 0000000 (i.e. file does not exist)
+2. GIT_FILEMODE_TREE            = 0040000
+3. GIT_FILEMODE_BLOB            = 0100644
+4. GIT_FILEMODE_BLOB_EXECUTABLE = 0100755
+5. GIT_FILEMODE_LINK            = 0120000
+6. GIT_FILEMODE_COMMIT          = 0160000
+
+I will try to have every type of transition somewhere in the history
+of this repo.

+# Threadsafe
+
+[![Build Status](https://travis-ci.org/headius/thread_safe.png)](https://travis-ci.org/headius/thread_safe)
+
+A collection of thread-safe versions of common core Ruby classes.
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+    gem 'thread_safe'
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install thread_safe
+
+## Usage
+
+```ruby
+require 'thread_safe'
+
+sa = ThreadSafe::Array.new # supports standard Array.new forms
+sh = ThreadSafe::Hash.new # supports standard Hash.new forms
+```
+
+`ThreadSafe::Cache` also exists, as a hash-like object, and should have
+much better performance characteristics esp. under high concurrency than
+`ThreadSafe::Hash`. However, `ThreadSafe::Cache` is not strictly semantically
+equivalent to a ruby `Hash` -- for instance, it does not necessarily retain
+ordering by insertion time as `Hash` does. For most uses it should do fine
+though, and we recommend you consider `ThreadSafe::Cache` instead of
+`ThreadSafe::Hash` for your concurrency-safe hash needs. It understands some
+options when created (depending on your ruby platform) that control some of the
+internals - when unsure just leave them out:
+
+
+```ruby
+require 'thread_safe'
+
+cache = ThreadSafe::Cache.new
+```
+
+## Contributing

+/**
+ * A hash table supporting full concurrency of retrievals and
+ * high expected concurrency for updates. This class obeys the
+ * same functional specification as {@link java.util.Hashtable}, and
+ * includes versions of methods corresponding to each method of
+ * {@code Hashtable}. However, even though all operations are
+ * thread-safe, retrieval operations do <em>not</em> entail locking,
+ * and there is <em>not</em> any support for locking the entire table
+ * in a way that prevents all access.  This class is fully
+ * interoperable with {@code Hashtable} in programs that rely on its
+ * thread safety but not on its synchronization details.
+ *
+ * <p>Retrieval operations (including {@code get}) generally do not
+ * block, so may overlap with update operations (including {@code put}
+ * and {@code remove}). Retrievals reflect the results of the most
+ * recently <em>completed</em> update operations holding upon their
+ * onset. (More formally, an update operation for a given key bears a
+ * <em>happens-before</em> relation with any (non-null) retrieval for
+ * that key reporting the updated value.)  For aggregate operations
+ * such as {@code putAll} and {@code clear}, concurrent retrievals may
+ * reflect insertion or removal of only some entries.  Similarly,
+ * Iterators and Enumerations return elements reflecting the state of
+ * the hash table at some point at or since the creation of the
+ * iterator/enumeration.  They do <em>not</em> throw {@link
+ * ConcurrentModificationException}.  However, iterators are designed
+ * to be used by only one thread at a time.  Bear in mind that the
+ * results of aggregate status methods including {@code size}, {@code
+ * isEmpty}, and {@code containsValue} are typically useful only when
+ * a map is not undergoing concurrent updates in other threads.
+ * Otherwise the results of these methods reflect transient states
+ * that may be adequate for monitoring or estimation purposes, but not
+ * for program control.
+ *
+ * <p>The table is dynamically expanded when there are too many
+ * collisions (i.e., keys that have distinct hash codes but fall into
+ * the same slot modulo the table size), with the expected average
+ * effect of maintaining roughly two bins per mapping (corresponding
+ * to a 0.75 load factor threshold for resizing). There may be much
+ * variance around this average as mappings are added and removed, but
+ * overall, this maintains a commonly accepted time/space tradeoff for
+ * hash tables.  However, resizing this or any other kind of hash
+ * table may be a relatively slow operation. When possible, it is a
+ * good idea to provide a size estimate as an optional {@code
+ * initialCapacity} constructor argument. An additional optional
+ * {@code loadFactor} constructor argument provides a further means of
+ * customizing initial table capacity by specifying the table density
+ * to be used in calculating the amount of space to allocate for the
+ * given number of elements.  Also, for compatibility with previous
+ * versions of this class, constructors may optionally specify an
+ * expected {@code concurrencyLevel} as an additional hint for
+ * internal sizing.  Note that using many keys with exactly the same
+ * {@code hashCode()} is a sure way to slow down performance of any
+ * hash table.
+ *
+ * <p>A {@link Set} projection of a ConcurrentHashMapV8 may be created
+ * (using {@link #newKeySet()} or {@link #newKeySet(int)}), or viewed
+ * (using {@link #keySet(Object)} when only keys are of interest, and the
+ * mapped values are (perhaps transiently) not used or all take the
+ * same mapping value.
+ *
+ * <p>A ConcurrentHashMapV8 can be used as scalable frequency map (a
+ * form of histogram or multiset) by using {@link LongAdder} values
+ * and initializing via {@link #computeIfAbsent}. For example, to add
+ * a count to a {@code ConcurrentHashMapV8<String,LongAdder> freqs}, you
+ * can use {@code freqs.computeIfAbsent(k -> new
+ * LongAdder()).increment();}
+ *
+ * <p>This class and its views and iterators implement all of the
+ * <em>optional</em> methods of the {@link Map} and {@link Iterator}
+ * interfaces.
+ *
+ * <p>Like {@link Hashtable} but unlike {@link HashMap}, this class
+ * does <em>not</em> allow {@code null} to be used as a key or value.
+ *
+ * <p>ConcurrentHashMapV8s support parallel operations using the {@link
+ * ForkJoinPool#commonPool}. (Tasks that may be used in other contexts
+ * are available in class {@link ForkJoinTasks}). These operations are
+ * designed to be safely, and often sensibly, applied even with maps
+ * that are being concurrently updated by other threads; for example,
+ * when computing a snapshot summary of the values in a shared
+ * registry.  There are three kinds of operation, each with four
+ * forms, accepting functions with Keys, Values, Entries, and (Key,
+ * Value) arguments and/or return values. (The first three forms are
+ * also available via the {@link #keySet()}, {@link #values()} and
+ * {@link #entrySet()} views). Because the elements of a
+ * ConcurrentHashMapV8 are not ordered in any particular way, and may be
+ * processed in different orders in different parallel executions, the
+ * correctness of supplied functions should not depend on any
+ * ordering, or on any other objects or values that may transiently
+ * change while computation is in progress; and except for forEach
+ * actions, should ideally be side-effect-free.
+ *
+ * <ul>
+ * <li> forEach: Perform a given action on each element.
+ * A variant form applies a given transformation on each element
+ * before performing the action.</li>
+ *
+ * <li> search: Return the first available non-null result of
+ * applying a given function on each element; skipping further
+ * search when a result is found.</li>
+ *
+ * <li> reduce: Accumulate each element.  The supplied reduction
+ * function cannot rely on ordering (more formally, it should be
+ * both associative and commutative).  There are five variants:
+ *
+ * <ul>
+ *
+ * <li> Plain reductions. (There is not a form of this method for
+ * (key, value) function arguments since there is no corresponding
+ * return type.)</li>
+ *
+ * <li> Mapped reductions that accumulate the results of a given
+ * function applied to each element.</li>
+ *
+ * <li> Reductions to scalar doubles, longs, and ints, using a
+ * given basis value.</li>
+ *
+ * </li>
+ * </ul>
+ * </ul>
+ *
+ * <p>The concurrency properties of bulk operations follow
+ * from those of ConcurrentHashMapV8: Any non-null result returned
+ * from {@code get(key)} and related access methods bears a
+ * happens-before relation with the associated insertion or
+ * update.  The result of any bulk operation reflects the
+ * composition of these per-element relations (but is not
+ * necessarily atomic with respect to the map as a whole unless it
+ * is somehow known to be quiescent).  Conversely, because keys
+ * and values in the map are never null, null serves as a reliable
+ * atomic indicator of the current lack of any result.  To
+ * maintain this property, null serves as an implicit basis for
+ * all non-scalar reduction operations. For the double, long, and
+ * int versions, the basis should be one that, when combined with
+ * any other value, returns that other value (more formally, it
+ * should be the identity element for the reduction). Most common
+ * reductions have these properties; for example, computing a sum
+ * with basis 0 or a minimum with basis MAX_VALUE.
+ *
+ * <p>Search and transformation functions provided as arguments
+ * should similarly return null to indicate the lack of any result
+ * (in which case it is not used). In the case of mapped
+ * reductions, this also enables transformations to serve as
+ * filters, returning null (or, in the case of primitive
+ * specializations, the identity basis) if the element should not
+ * be combined. You can create compound transformations and
+ * filterings by composing them yourself under this "null means
+ * there is nothing there now" rule before using them in search or
+ * reduce operations.
+ *
+ * <p>Methods accepting and/or returning Entry arguments maintain
+ * key-value associations. They may be useful for example when
+ * finding the key for the greatest value. Note that "plain" Entry
+ * arguments can be supplied using {@code new
+ * AbstractMap.SimpleEntry(k,v)}.
+ *
+ * <p>Bulk operations may complete abruptly, throwing an
+ * exception encountered in the application of a supplied
+ * function. Bear in mind when handling such exceptions that other
+ * concurrently executing functions could also have thrown
+ * exceptions, or would have done so if the first exception had
+ * not occurred.
+ *
+ * <p>Parallel speedups for bulk operations compared to sequential
+ * processing are common but not guaranteed.  Operations involving
+ * brief functions on small maps may execute more slowly than
+ * sequential loops if the underlying work to parallelize the
+ * computation is more expensive than the computation itself.
+ * Similarly, parallelization may not lead to much actual parallelism
+ * if all processors are busy performing unrelated tasks.
+ *
+ * <p>All arguments to all task methods must be non-null.
+ *

+    /*
+     * Overview:
+     *
+     * The primary design goal of this hash table is to maintain
+     * concurrent readability (typically method get(), but also
+     * iterators and related methods) while minimizing update
+     * contention. Secondary goals are to keep space consumption about
+     * the same or better than java.util.HashMap, and to support high
+     * initial insertion rates on an empty table by many threads.
+     *
+     * Each key-value mapping is held in a Node.  Because Node fields
+     * can contain special values, they are defined using plain Object
+     * types. Similarly in turn, all internal methods that use them
+     * work off Object types. And similarly, so do the internal
+     * methods of auxiliary iterator and view classes.  All public
+     * generic typed methods relay in/out of these internal methods,
+     * supplying null-checks and casts as needed. This also allows
+     * many of the public methods to be factored into a smaller number
+     * of internal methods (although sadly not so for the five
+     * variants of put-related operations). The validation-based
+     * approach explained below leads to a lot of code sprawl because
+     * retry-control precludes factoring into smaller methods.
+     *
+     * The table is lazily initialized to a power-of-two size upon the
+     * first insertion.  Each bin in the table normally contains a
+     * list of Nodes (most often, the list has only zero or one Node).
+     * Table accesses require volatile/atomic reads, writes, and
+     * CASes.  Because there is no other way to arrange this without
+     * adding further indirections, we use intrinsics
+     * (sun.misc.Unsafe) operations.  The lists of nodes within bins
+     * are always accurately traversable under volatile reads, so long
+     * as lookups check hash code and non-nullness of value before
+     * checking key equality.
+     *
+     * We use the top two bits of Node hash fields for control
+     * purposes -- they are available anyway because of addressing
+     * constraints.  As explained further below, these top bits are
+     * used as follows:
+     *  00 - Normal
+     *  01 - Locked
+     *  11 - Locked and may have a thread waiting for lock
+     *  10 - Node is a forwarding node
+     *
+     * The lower 30 bits of each Node's hash field contain a
+     * transformation of the key's hash code, except for forwarding
+     * nodes, for which the lower bits are zero (and so always have
+     * hash field == MOVED).
+     *
+     * Insertion (via put or its variants) of the first node in an
+     * empty bin is performed by just CASing it to the bin.  This is
+     * by far the most common case for put operations under most
+     * key/hash distributions.  Other update operations (insert,
+     * delete, and replace) require locks.  We do not want to waste
+     * the space required to associate a distinct lock object with
+     * each bin, so instead use the first node of a bin list itself as
+     * a lock. Blocking support for these locks relies on the builtin
+     * "synchronized" monitors.  However, we also need a tryLock
+     * construction, so we overlay these by using bits of the Node
+     * hash field for lock control (see above), and so normally use
+     * builtin monitors only for blocking and signalling using
+     * wait/notifyAll constructions. See Node.tryAwaitLock.
+     *
+     * Using the first node of a list as a lock does not by itself
+     * suffice though: When a node is locked, any update must first
+     * validate that it is still the first node after locking it, and
+     * retry if not. Because new nodes are always appended to lists,
+     * once a node is first in a bin, it remains first until deleted
+     * or the bin becomes invalidated (upon resizing).  However,
+     * operations that only conditionally update may inspect nodes
+     * until the point of update. This is a converse of sorts to the
+     * lazy locking technique described by Herlihy & Shavit.
+     *
+     * The main disadvantage of per-bin locks is that other update
+     * operations on other nodes in a bin list protected by the same
+     * lock can stall, for example when user equals() or mapping
+     * functions take a long time.  However, statistically, under
+     * random hash codes, this is not a common problem.  Ideally, the
+     * frequency of nodes in bins follows a Poisson distribution
+     * (http://en.wikipedia.org/wiki/Poisson_distribution) with a
+     * parameter of about 0.5 on average, given the resizing threshold
+     * of 0.75, although with a large variance because of resizing
+     * granularity. Ignoring variance, the expected occurrences of
+     * list size k are (exp(-0.5) * pow(0.5, k) / factorial(k)). The
+     * first values are:
+     *
+     * 0:    0.60653066
+     * 1:    0.30326533
+     * 2:    0.07581633
+     * 3:    0.01263606
+     * 4:    0.00157952
+     * 5:    0.00015795
+     * 6:    0.00001316
+     * 7:    0.00000094
+     * 8:    0.00000006
+     * more: less than 1 in ten million
+     *
+     * Lock contention probability for two threads accessing distinct
+     * elements is roughly 1 / (8 * #elements) under random hashes.
+     *
+     * Actual hash code distributions encountered in practice
+     * sometimes deviate significantly from uniform randomness.  This
+     * includes the case when N > (1<<30), so some keys MUST collide.
+     * Similarly for dumb or hostile usages in which multiple keys are
+     * designed to have identical hash codes. Also, although we guard
+     * against the worst effects of this (see method spread), sets of
+     * hashes may differ only in bits that do not impact their bin
+     * index for a given power-of-two mask.  So we use a secondary
+     * strategy that applies when the number of nodes in a bin exceeds
+     * a threshold, and at least one of the keys implements
+     * Comparable.  These TreeBins use a balanced tree to hold nodes
+     * (a specialized form of red-black trees), bounding search time
+     * to O(log N).  Each search step in a TreeBin is around twice as
+     * slow as in a regular list, but given that N cannot exceed
+     * (1<<64) (before running out of addresses) this bounds search
+     * steps, lock hold times, etc, to reasonable constants (roughly
+     * 100 nodes inspected per operation worst case) so long as keys
+     * are Comparable (which is very common -- String, Long, etc).
+     * TreeBin nodes (TreeNodes) also maintain the same "next"
+     * traversal pointers as regular nodes, so can be traversed in
+     * iterators in the same way.
+     *
+     * The table is resized when occupancy exceeds a percentage
+     * threshold (nominally, 0.75, but see below).  Only a single
+     * thread performs the resize (using field "sizeCtl", to arrange
+     * exclusion), but the table otherwise remains usable for reads
+     * and updates. Resizing proceeds by transferring bins, one by
+     * one, from the table to the next table.  Because we are using
+     * power-of-two expansion, the elements from each bin must either
+     * stay at same index, or move with a power of two offset. We
+     * eliminate unnecessary node creation by catching cases where old
+     * nodes can be reused because their next fields won't change.  On
+     * average, only about one-sixth of them need cloning when a table
+     * doubles. The nodes they replace will be garbage collectable as
+     * soon as they are no longer referenced by any reader thread that
+     * may be in the midst of concurrently traversing table.  Upon
+     * transfer, the old table bin contains only a special forwarding
+     * node (with hash field "MOVED") that contains the next table as
+     * its key. On encountering a forwarding node, access and update
+     * operations restart, using the new table.
+     *
+     * Each bin transfer requires its bin lock. However, unlike other
+     * cases, a transfer can skip a bin if it fails to acquire its
+     * lock, and revisit it later (unless it is a TreeBin). Method
+     * rebuild maintains a buffer of TRANSFER_BUFFER_SIZE bins that
+     * have been skipped because of failure to acquire a lock, and
+     * blocks only if none are available (i.e., only very rarely).
+     * The transfer operation must also ensure that all accessible
+     * bins in both the old and new table are usable by any traversal.
+     * When there are no lock acquisition failures, this is arranged
+     * simply by proceeding from the last bin (table.length - 1) up
+     * towards the first.  Upon seeing a forwarding node, traversals
+     * (see class Iter) arrange to move to the new table
+     * without revisiting nodes.  However, when any node is skipped
+     * during a transfer, all earlier table bins may have become
+     * visible, so are initialized with a reverse-forwarding node back
+     * to the old table until the new ones are established. (This
+     * sometimes requires transiently locking a forwarding node, which
+     * is possible under the above encoding.) These more expensive
+     * mechanics trigger only when necessary.
+     *
+     * The traversal scheme also applies to partial traversals of
+     * ranges of bins (via an alternate Traverser constructor)
+     * to support partitioned aggregate operations.  Also, read-only
+     * operations give up if ever forwarded to a null table, which
+     * provides support for shutdown-style clearing, which is also not
+     * currently implemented.
+     *
+     * Lazy table initialization minimizes footprint until first use,
+     * and also avoids resizings when the first operation is from a
+     * putAll, constructor with map argument, or deserialization.
+     * These cases attempt to override the initial capacity settings,
+     * but harmlessly fail to take effect in cases of races.
+     *
+     * The element count is maintained using a LongAdder, which avoids
+     * contention on updates but can encounter cache thrashing if read
+     * too frequently during concurrent access. To avoid reading so
+     * often, resizing is attempted either when a bin lock is
+     * contended, or upon adding to a bin already holding two or more
+     * nodes (checked before adding in the xIfAbsent methods, after
+     * adding in others). Under uniform hash distributions, the
+     * probability of this occurring at threshold is around 13%,
+     * meaning that only about 1 in 8 puts check threshold (and after
+     * resizing, many fewer do so). But this approximation has high
+     * variance for small table sizes, so we check on any collision
+     * for sizes <= 64. The bulk putAll operation further reduces
+     * contention by only committing count updates upon these size
+     * checks.
+     *
+     * Maintaining API and serialization compatibility with previous
+     * versions of this class introduces several oddities. Mainly: We
+     * leave untouched but unused constructor arguments refering to
+     * concurrencyLevel. We accept a loadFactor constructor argument,
+     * but apply it only to initial table capacity (which is the only
+     * time that we can guarantee to honor it.) We also declare an
+     * unused "Segment" class that is instantiated in minimal form
+     * only when serializing.

+     * A specialized form of red-black tree for use in bins
+     * whose size exceeds a threshold.
+     *
+     * TreeBins use a special form of comparison for search and
+     * related operations (which is the main reason we cannot use
+     * existing collections such as TreeMaps). TreeBins contain
+     * Comparable elements, but may contain others, as well as
+     * elements that are Comparable but not necessarily Comparable<T>
+     * for the same T, so we cannot invoke compareTo among them. To
+     * handle this, the tree is ordered primarily by hash value, then
+     * by getClass().getName() order, and then by Comparator order
+     * among elements of the same class.  On lookup at a node, if
+     * elements are not comparable or compare as 0, both left and
+     * right children may need to be searched in the case of tied hash
+     * values. (This corresponds to the full list search that would be
+     * necessary if all elements were non-Comparable and had tied
+     * hashes.)  The red-black balancing code is updated from
+     * pre-jdk-collections
+     * (http://gee.cs.oswego.edu/dl/classes/collections/RBCell.java)
+     * based in turn on Cormen, Leiserson, and Rivest "Introduction to
+     * Algorithms" (CLR).
+     *
+     * TreeBins also maintain a separate locking discipline than
+     * regular bins. Because they are forwarded via special MOVED
+     * nodes at bin heads (which can never change once established),
+     * we cannot use those nodes as locks. Instead, TreeBin
+     * extends AbstractQueuedSynchronizer to support a simple form of
+     * read-write lock. For update operations and table validation,
+     * the exclusive form of lock behaves in the same way as bin-head
+     * locks. However, lookups use shared read-lock mechanics to allow
+     * multiple readers in the absence of writers.  Additionally,
+     * these lookups do not ever block: While the lock is not
+     * available, they proceed along the slow traversal path (via
+     * next-pointers) until the lock becomes available or the list is
+     * exhausted, whichever comes first. (These cases are not fast,
+     * but maximize aggregate expected throughput.)  The AQS mechanics
+     * for doing this are straightforward.  The lock state is held as
+     * AQS getState().  Read counts are negative; the write count (1)
+     * is positive.  There are no signalling preferences among readers
+     * and writers. Since we don't need to export full Lock API, we
+     * just override the minimal AQS methods and use them directly.

+     *  5. Lock and validate; if valid, scan and add or update
+     *
+     * The others interweave other checks and/or alternative actions:
+     *  * Plain put checks for and performs resize after insertion.
+     *  * putIfAbsent prescans for mapping without lock (and fails to add
+     *    if present), which also makes pre-emptive resize checks worthwhile.
+     *  * computeIfAbsent extends form used in putIfAbsent with additional
+     *    mechanics to deal with, calls, potential exceptions and null
+     *    returns from function call.
+     *  * compute uses the same function-call mechanics, but without

+     *  * merge acts as putIfAbsent in the absent case, but invokes the
+     *    update function if present
+     *  * putAll attempts to pre-allocate enough table space
+     *    and more lazily performs count updates and checks.

+    /**
+     * Encapsulates traversal for methods such as containsValue; also
+     * serves as a base class for other iterators and bulk tasks.
+     *
+     * At each step, the iterator snapshots the key ("nextKey") and
+     * value ("nextVal") of a valid node (i.e., one that, at point of
+     * snapshot, has a non-null user value). Because val fields can
+     * change (including to null, indicating deletion), field nextVal
+     * might not be accurate at point of use, but still maintains the
+     * weak consistency property of holding a value that was once
+     * valid. To support iterator.remove, the nextKey field is not
+     * updated (nulled out) when the iterator cannot advance.
+     *
+     * Internal traversals directly access these fields, as in:
+     * {@code while (it.advance() != null) { process(it.nextKey); }}
+     *
+     * Exported iterators must track whether the iterator has advanced
+     * (in hasNext vs next) (by setting/checking/nulling field
+     * nextVal), and then extract key, value, or key-value pairs as
+     * return values of next().
+     *
+     * The iterator visits once each still-valid node that was
+     * reachable upon iterator construction. It might miss some that
+     * were added to a bin after the bin was visited, which is OK wrt
+     * consistency guarantees. Maintaining this property in the face
+     * of possible ongoing resizes requires a fair amount of
+     * bookkeeping state that is difficult to optimize away amidst
+     * volatile accesses.  Even so, traversal maintains reasonable
+     * throughput.
+     *
+     * Normally, iteration proceeds bin-by-bin traversing lists.
+     * However, if the table has been resized, then all future steps
+     * must traverse both the bin at the current index as well as at
+     * (index + baseSize); and so on for further resizings. To
+     * paranoically cope with potential sharing by users of iterators
+     * across threads, iteration terminates if a bounds checks fails
+     * for a table read.
+     *
+     * This class extends ForkJoinTask to streamline parallel
+     * iteration in bulk operations (see BulkTask). This adds only an
+     * int of space overhead, which is close enough to negligible in
+     * cases where it is not needed to not worry about it.  Because
+     * ForkJoinTask is Serializable, but iterators need not be, we
+     * need to add warning suppressions.

+     * This class maintains a lazily-initialized table of atomically
+     * updated variables, plus an extra "base" field. The table size
+     * is a power of two. Indexing uses masked per-thread hash codes.
+     * Nearly all declarations in this class are package-private,
+     * accessed directly by subclasses.
+     *
+     * Table entries are of class Cell; a variant of AtomicLong padded
+     * to reduce cache contention on most processors. Padding is
+     * overkill for most Atomics because they are usually irregularly
+     * scattered in memory and thus don't interfere much with each
+     * other. But Atomic objects residing in arrays will tend to be
+     * placed adjacent to each other, and so will most often share
+     * cache lines (with a huge negative performance impact) without
+     * this precaution.
+     *
+     * In part because Cells are relatively large, we avoid creating
+     * them until they are needed.  When there is no contention, all
+     * updates are made to the base field.  Upon first contention (a
+     * failed CAS on base update), the table is initialized to size 2.
+     * The table size is doubled upon further contention until
+     * reaching the nearest power of two greater than or equal to the
+     * number of CPUS. Table slots remain empty (null) until they are
+     * needed.
+     *
+     * A single spinlock ("busy") is used for initializing and
+     * resizing the table, as well as populating slots with new Cells.
+     * There is no need for a blocking lock: When the lock is not
+     * available, threads try other slots (or the base).  During these
+     * retries, there is increased contention and reduced locality,
+     * which is still better than alternatives.
+     *
+     * Per-thread hash codes are initialized to random values.
+     * Contention and/or table collisions are indicated by failed
+     * CASes when performing an update operation (see method
+     * retryUpdate). Upon a collision, if the table size is less than
+     * the capacity, it is doubled in size unless some other thread
+     * holds the lock. If a hashed slot is empty, and lock is
+     * available, a new Cell is created. Otherwise, if the slot
+     * exists, a CAS is tried.  Retries proceed by "double hashing",
+     * using a secondary hash (Marsaglia XorShift) to try to find a
+     * free slot.
+     *
+     * The table size is capped because, when there are more threads
+     * than CPUs, supposing that each thread were bound to a CPU,
+     * there would exist a perfect hash function mapping threads to
+     * slots that eliminates collisions. When we reach capacity, we
+     * search for this mapping by randomly varying the hash codes of
+     * colliding threads.  Because search is random, and collisions
+     * only become known via CAS failures, convergence can be slow,
+     * and because threads are typically not bound to CPUS forever,
+     * may not occur at all. However, despite these limitations,
+     * observed contention rates are typically low in these cases.
+     *
+     * It is possible for a Cell to become unused when threads that
+     * once hashed to it terminate, as well as in the case where
+     * doubling the table causes no thread to hash to it under
+     * expanded mask.  We do not try to detect or remove such cells,
+     * under the assumption that for long-running instances, observed
+     * contention levels will recur, so the cells will eventually be
+     * needed again; and for short-lived ones, it does not matter.

+/**
+ * A hash table supporting full concurrency of retrievals and
+ * high expected concurrency for updates. This class obeys the
+ * same functional specification as {@link java.util.Hashtable}, and
+ * includes versions of methods corresponding to each method of
+ * {@code Hashtable}. However, even though all operations are
+ * thread-safe, retrieval operations do <em>not</em> entail locking,
+ * and there is <em>not</em> any support for locking the entire table
+ * in a way that prevents all access.  This class is fully
+ * interoperable with {@code Hashtable} in programs that rely on its
+ * thread safety but not on its synchronization details.
+ *
+ * <p>Retrieval operations (including {@code get}) generally do not
+ * block, so may overlap with update operations (including {@code put}
+ * and {@code remove}). Retrievals reflect the results of the most
+ * recently <em>completed</em> update operations holding upon their
+ * onset. (More formally, an update operation for a given key bears a
+ * <em>happens-before</em> relation with any (non-null) retrieval for
+ * that key reporting the updated value.)  For aggregate operations
+ * such as {@code putAll} and {@code clear}, concurrent retrievals may
+ * reflect insertion or removal of only some entries.  Similarly,
+ * Iterators and Enumerations return elements reflecting the state of
+ * the hash table at some point at or since the creation of the
+ * iterator/enumeration.  They do <em>not</em> throw {@link
+ * ConcurrentModificationException}.  However, iterators are designed
+ * to be used by only one thread at a time.  Bear in mind that the
+ * results of aggregate status methods including {@code size}, {@code
+ * isEmpty}, and {@code containsValue} are typically useful only when
+ * a map is not undergoing concurrent updates in other threads.
+ * Otherwise the results of these methods reflect transient states
+ * that may be adequate for monitoring or estimation purposes, but not
+ * for program control.
+ *
+ * <p>The table is dynamically expanded when there are too many
+ * collisions (i.e., keys that have distinct hash codes but fall into
+ * the same slot modulo the table size), with the expected average
+ * effect of maintaining roughly two bins per mapping (corresponding
+ * to a 0.75 load factor threshold for resizing). There may be much
+ * variance around this average as mappings are added and removed, but
+ * overall, this maintains a commonly accepted time/space tradeoff for
+ * hash tables.  However, resizing this or any other kind of hash
+ * table may be a relatively slow operation. When possible, it is a
+ * good idea to provide a size estimate as an optional {@code
+ * initialCapacity} constructor argument. An additional optional
+ * {@code loadFactor} constructor argument provides a further means of
+ * customizing initial table capacity by specifying the table density
+ * to be used in calculating the amount of space to allocate for the
+ * given number of elements.  Also, for compatibility with previous
+ * versions of this class, constructors may optionally specify an
+ * expected {@code concurrencyLevel} as an additional hint for
+ * internal sizing.  Note that using many keys with exactly the same
+ * {@code hashCode()} is a sure way to slow down performance of any
+ * hash table.
+ *
+ * <p>A {@link Set} projection of a ConcurrentHashMapV8 may be created
+ * (using {@link #newKeySet()} or {@link #newKeySet(int)}), or viewed
+ * (using {@link #keySet(Object)} when only keys are of interest, and the
+ * mapped values are (perhaps transiently) not used or all take the
+ * same mapping value.
+ *
+ * <p>A ConcurrentHashMapV8 can be used as scalable frequency map (a
+ * form of histogram or multiset) by using {@link LongAdder} values
+ * and initializing via {@link #computeIfAbsent}. For example, to add
+ * a count to a {@code ConcurrentHashMapV8<String,LongAdder> freqs}, you
+ * can use {@code freqs.computeIfAbsent(k -> new
+ * LongAdder()).increment();}
+ *
+ * <p>This class and its views and iterators implement all of the
+ * <em>optional</em> methods of the {@link Map} and {@link Iterator}
+ * interfaces.
+ *
+ * <p>Like {@link Hashtable} but unlike {@link HashMap}, this class
+ * does <em>not</em> allow {@code null} to be used as a key or value.
+ *
+ * <p>ConcurrentHashMapV8s support parallel operations using the {@link
+ * ForkJoinPool#commonPool}. (Tasks that may be used in other contexts
+ * are available in class {@link ForkJoinTasks}). These operations are
+ * designed to be safely, and often sensibly, applied even with maps
+ * that are being concurrently updated by other threads; for example,
+ * when computing a snapshot summary of the values in a shared
+ * registry.  There are three kinds of operation, each with four
+ * forms, accepting functions with Keys, Values, Entries, and (Key,
+ * Value) arguments and/or return values. (The first three forms are
+ * also available via the {@link #keySet()}, {@link #values()} and
+ * {@link #entrySet()} views). Because the elements of a
+ * ConcurrentHashMapV8 are not ordered in any particular way, and may be
+ * processed in different orders in different parallel executions, the
+ * correctness of supplied functions should not depend on any
+ * ordering, or on any other objects or values that may transiently
+ * change while computation is in progress; and except for forEach
+ * actions, should ideally be side-effect-free.
+ *
+ * <ul>
+ * <li> forEach: Perform a given action on each element.
+ * A variant form applies a given transformation on each element
+ * before performing the action.</li>
+ *
+ * <li> search: Return the first available non-null result of
+ * applying a given function on each element; skipping further
+ * search when a result is found.</li>
+ *
+ * <li> reduce: Accumulate each element.  The supplied reduction
+ * function cannot rely on ordering (more formally, it should be
+ * both associative and commutative).  There are five variants:
+ *
+ * <ul>
+ *
+ * <li> Plain reductions. (There is not a form of this method for
+ * (key, value) function arguments since there is no corresponding
+ * return type.)</li>
+ *
+ * <li> Mapped reductions that accumulate the results of a given
+ * function applied to each element.</li>
+ *
+ * <li> Reductions to scalar doubles, longs, and ints, using a
+ * given basis value.</li>
+ *
+ * </li>
+ * </ul>
+ * </ul>
+ *
+ * <p>The concurrency properties of bulk operations follow
+ * from those of ConcurrentHashMapV8: Any non-null result returned
+ * from {@code get(key)} and related access methods bears a
+ * happens-before relation with the associated insertion or
+ * update.  The result of any bulk operation reflects the
+ * composition of these per-element relations (but is not
+ * necessarily atomic with respect to the map as a whole unless it
+ * is somehow known to be quiescent).  Conversely, because keys
+ * and values in the map are never null, null serves as a reliable
+ * atomic indicator of the current lack of any result.  To
+ * maintain this property, null serves as an implicit basis for
+ * all non-scalar reduction operations. For the double, long, and
+ * int versions, the basis should be one that, when combined with
+ * any other value, returns that other value (more formally, it
+ * should be the identity element for the reduction). Most common
+ * reductions have these properties; for example, computing a sum
+ * with basis 0 or a minimum with basis MAX_VALUE.
+ *
+ * <p>Search and transformation functions provided as arguments
+ * should similarly return null to indicate the lack of any result
+ * (in which case it is not used). In the case of mapped
+ * reductions, this also enables transformations to serve as
+ * filters, returning null (or, in the case of primitive
+ * specializations, the identity basis) if the element should not
+ * be combined. You can create compound transformations and
+ * filterings by composing them yourself under this "null means
+ * there is nothing there now" rule before using them in search or
+ * reduce operations.
+ *
+ * <p>Methods accepting and/or returning Entry arguments maintain
+ * key-value associations. They may be useful for example when
+ * finding the key for the greatest value. Note that "plain" Entry
+ * arguments can be supplied using {@code new
+ * AbstractMap.SimpleEntry(k,v)}.
+ *
+ * <p>Bulk operations may complete abruptly, throwing an
+ * exception encountered in the application of a supplied
+ * function. Bear in mind when handling such exceptions that other
+ * concurrently executing functions could also have thrown
+ * exceptions, or would have done so if the first exception had
+ * not occurred.
+ *
+ * <p>Parallel speedups for bulk operations compared to sequential
+ * processing are common but not guaranteed.  Operations involving
+ * brief functions on small maps may execute more slowly than
+ * sequential loops if the underlying work to parallelize the
+ * computation is more expensive than the computation itself.
+ * Similarly, parallelization may not lead to much actual parallelism
+ * if all processors are busy performing unrelated tasks.
+ *
+ * <p>All arguments to all task methods must be non-null.
+ *

+ * uses nested functional interfaces with different names but the
+ * same forms as those expected for JDK8.</em>

+     * Overview:
+     *
+     * The primary design goal of this hash table is to maintain
+     * concurrent readability (typically method get(), but also
+     * iterators and related methods) while minimizing update
+     * contention. Secondary goals are to keep space consumption about
+     * the same or better than java.util.HashMap, and to support high
+     * initial insertion rates on an empty table by many threads.
+     *
+     * Each key-value mapping is held in a Node.  Because Node fields
+     * can contain special values, they are defined using plain Object
+     * types. Similarly in turn, all internal methods that use them
+     * work off Object types. And similarly, so do the internal
+     * methods of auxiliary iterator and view classes.  All public
+     * generic typed methods relay in/out of these internal methods,
+     * supplying null-checks and casts as needed. This also allows
+     * many of the public methods to be factored into a smaller number
+     * of internal methods (although sadly not so for the five
+     * variants of put-related operations). The validation-based
+     * approach explained below leads to a lot of code sprawl because
+     * retry-control precludes factoring into smaller methods.
+     *
+     * The table is lazily initialized to a power-of-two size upon the
+     * first insertion.  Each bin in the table normally contains a
+     * list of Nodes (most often, the list has only zero or one Node).
+     * Table accesses require volatile/atomic reads, writes, and
+     * CASes.  Because there is no other way to arrange this without
+     * adding further indirections, we use intrinsics
+     * (sun.misc.Unsafe) operations.  The lists of nodes within bins
+     * are always accurately traversable under volatile reads, so long
+     * as lookups check hash code and non-nullness of value before
+     * checking key equality.
+     *
+     * We use the top two bits of Node hash fields for control
+     * purposes -- they are available anyway because of addressing
+     * constraints.  As explained further below, these top bits are
+     * used as follows:
+     *  00 - Normal
+     *  01 - Locked
+     *  11 - Locked and may have a thread waiting for lock
+     *  10 - Node is a forwarding node
+     *
+     * The lower 30 bits of each Node's hash field contain a
+     * transformation of the key's hash code, except for forwarding
+     * nodes, for which the lower bits are zero (and so always have
+     * hash field == MOVED).
+     *
+     * Insertion (via put or its variants) of the first node in an
+     * empty bin is performed by just CASing it to the bin.  This is
+     * by far the most common case for put operations under most
+     * key/hash distributions.  Other update operations (insert,
+     * delete, and replace) require locks.  We do not want to waste
+     * the space required to associate a distinct lock object with
+     * each bin, so instead use the first node of a bin list itself as
+     * a lock. Blocking support for these locks relies on the builtin
+     * "synchronized" monitors.  However, we also need a tryLock
+     * construction, so we overlay these by using bits of the Node
+     * hash field for lock control (see above), and so normally use
+     * builtin monitors only for blocking and signalling using
+     * wait/notifyAll constructions. See Node.tryAwaitLock.
+     *
+     * Using the first node of a list as a lock does not by itself
+     * suffice though: When a node is locked, any update must first
+     * validate that it is still the first node after locking it, and
+     * retry if not. Because new nodes are always appended to lists,
+     * once a node is first in a bin, it remains first until deleted
+     * or the bin becomes invalidated (upon resizing).  However,
+     * operations that only conditionally update may inspect nodes
+     * until the point of update. This is a converse of sorts to the
+     * lazy locking technique described by Herlihy & Shavit.
+     *
+     * The main disadvantage of per-bin locks is that other update
+     * operations on other nodes in a bin list protected by the same
+     * lock can stall, for example when user equals() or mapping
+     * functions take a long time.  However, statistically, under
+     * random hash codes, this is not a common problem.  Ideally, the
+     * frequency of nodes in bins follows a Poisson distribution
+     * (http://en.wikipedia.org/wiki/Poisson_distribution) with a
+     * parameter of about 0.5 on average, given the resizing threshold
+     * of 0.75, although with a large variance because of resizing
+     * granularity. Ignoring variance, the expected occurrences of
+     * list size k are (exp(-0.5) * pow(0.5, k) / factorial(k)). The
+     * first values are:
+     *
+     * 0:    0.60653066
+     * 1:    0.30326533
+     * 2:    0.07581633
+     * 3:    0.01263606
+     * 4:    0.00157952
+     * 5:    0.00015795
+     * 6:    0.00001316
+     * 7:    0.00000094
+     * 8:    0.00000006
+     * more: less than 1 in ten million
+     *
+     * Lock contention probability for two threads accessing distinct
+     * elements is roughly 1 / (8 * #elements) under random hashes.
+     *
+     * Actual hash code distributions encountered in practice
+     * sometimes deviate significantly from uniform randomness.  This
+     * includes the case when N > (1<<30), so some keys MUST collide.
+     * Similarly for dumb or hostile usages in which multiple keys are
+     * designed to have identical hash codes. Also, although we guard
+     * against the worst effects of this (see method spread), sets of
+     * hashes may differ only in bits that do not impact their bin
+     * index for a given power-of-two mask.  So we use a secondary
+     * strategy that applies when the number of nodes in a bin exceeds
+     * a threshold, and at least one of the keys implements
+     * Comparable.  These TreeBins use a balanced tree to hold nodes
+     * (a specialized form of red-black trees), bounding search time
+     * to O(log N).  Each search step in a TreeBin is around twice as
+     * slow as in a regular list, but given that N cannot exceed
+     * (1<<64) (before running out of addresses) this bounds search
+     * steps, lock hold times, etc, to reasonable constants (roughly
+     * 100 nodes inspected per operation worst case) so long as keys
+     * are Comparable (which is very common -- String, Long, etc).
+     * TreeBin nodes (TreeNodes) also maintain the same "next"
+     * traversal pointers as regular nodes, so can be traversed in
+     * iterators in the same way.
+     *
+     * The table is resized when occupancy exceeds a percentage
+     * threshold (nominally, 0.75, but see below).  Only a single
+     * thread performs the resize (using field "sizeCtl", to arrange
+     * exclusion), but the table otherwise remains usable for reads
+     * and updates. Resizing proceeds by transferring bins, one by
+     * one, from the table to the next table.  Because we are using
+     * power-of-two expansion, the elements from each bin must either
+     * stay at same index, or move with a power of two offset. We
+     * eliminate unnecessary node creation by catching cases where old
+     * nodes can be reused because their next fields won't change.  On
+     * average, only about one-sixth of them need cloning when a table
+     * doubles. The nodes they replace will be garbage collectable as
+     * soon as they are no longer referenced by any reader thread that
+     * may be in the midst of concurrently traversing table.  Upon
+     * transfer, the old table bin contains only a special forwarding
+     * node (with hash field "MOVED") that contains the next table as
+     * its key. On encountering a forwarding node, access and update
+     * operations restart, using the new table.
+     *
+     * Each bin transfer requires its bin lock. However, unlike other
+     * cases, a transfer can skip a bin if it fails to acquire its
+     * lock, and revisit it later (unless it is a TreeBin). Method
+     * rebuild maintains a buffer of TRANSFER_BUFFER_SIZE bins that
+     * have been skipped because of failure to acquire a lock, and
+     * blocks only if none are available (i.e., only very rarely).
+     * The transfer operation must also ensure that all accessible
+     * bins in both the old and new table are usable by any traversal.
+     * When there are no lock acquisition failures, this is arranged
+     * simply by proceeding from the last bin (table.length - 1) up
+     * towards the first.  Upon seeing a forwarding node, traversals
+     * (see class Iter) arrange to move to the new table
+     * without revisiting nodes.  However, when any node is skipped
+     * during a transfer, all earlier table bins may have become
+     * visible, so are initialized with a reverse-forwarding node back
+     * to the old table until the new ones are established. (This
+     * sometimes requires transiently locking a forwarding node, which
+     * is possible under the above encoding.) These more expensive
+     * mechanics trigger only when necessary.
+     *
+     * The traversal scheme also applies to partial traversals of
+     * ranges of bins (via an alternate Traverser constructor)
+     * to support partitioned aggregate operations.  Also, read-only
+     * operations give up if ever forwarded to a null table, which
+     * provides support for shutdown-style clearing, which is also not
+     * currently implemented.
+     *
+     * Lazy table initialization minimizes footprint until first use,
+     * and also avoids resizings when the first operation is from a
+     * putAll, constructor with map argument, or deserialization.
+     * These cases attempt to override the initial capacity settings,
+     * but harmlessly fail to take effect in cases of races.
+     *
+     * The element count is maintained using a LongAdder, which avoids
+     * contention on updates but can encounter cache thrashing if read
+     * too frequently during concurrent access. To avoid reading so
+     * often, resizing is attempted either when a bin lock is
+     * contended, or upon adding to a bin already holding two or more
+     * nodes (checked before adding in the xIfAbsent methods, after
+     * adding in others). Under uniform hash distributions, the
+     * probability of this occurring at threshold is around 13%,
+     * meaning that only about 1 in 8 puts check threshold (and after
+     * resizing, many fewer do so). But this approximation has high
+     * variance for small table sizes, so we check on any collision
+     * for sizes <= 64. The bulk putAll operation further reduces
+     * contention by only committing count updates upon these size
+     * checks.
+     *
+     * Maintaining API and serialization compatibility with previous
+     * versions of this class introduces several oddities. Mainly: We
+     * leave untouched but unused constructor arguments refering to
+     * concurrencyLevel. We accept a loadFactor constructor argument,
+     * but apply it only to initial table capacity (which is the only
+     * time that we can guarantee to honor it.) We also declare an
+     * unused "Segment" class that is instantiated in minimal form

+    /**
+     * Encapsulates traversal for methods such as containsValue; also
+     * serves as a base class for other iterators and bulk tasks.
+     *
+     * At each step, the iterator snapshots the key ("nextKey") and
+     * value ("nextVal") of a valid node (i.e., one that, at point of
+     * snapshot, has a non-null user value). Because val fields can
+     * change (including to null, indicating deletion), field nextVal
+     * might not be accurate at point of use, but still maintains the
+     * weak consistency property of holding a value that was once
+     * valid. To support iterator.remove, the nextKey field is not
+     * updated (nulled out) when the iterator cannot advance.
+     *
+     * Internal traversals directly access these fields, as in:
+     * {@code while (it.advance() != null) { process(it.nextKey); }}
+     *
+     * Exported iterators must track whether the iterator has advanced
+     * (in hasNext vs next) (by setting/checking/nulling field
+     * nextVal), and then extract key, value, or key-value pairs as
+     * return values of next().
+     *
+     * The iterator visits once each still-valid node that was
+     * reachable upon iterator construction. It might miss some that
+     * were added to a bin after the bin was visited, which is OK wrt
+     * consistency guarantees. Maintaining this property in the face
+     * of possible ongoing resizes requires a fair amount of
+     * bookkeeping state that is difficult to optimize away amidst
+     * volatile accesses.  Even so, traversal maintains reasonable
+     * throughput.
+     *
+     * Normally, iteration proceeds bin-by-bin traversing lists.
+     * However, if the table has been resized, then all future steps
+     * must traverse both the bin at the current index as well as at
+     * (index + baseSize); and so on for further resizings. To
+     * paranoically cope with potential sharing by users of iterators
+     * across threads, iteration terminates if a bounds checks fails
+     * for a table read.
+     *
+     * This class extends ForkJoinTask to streamline parallel
+     * iteration in bulk operations (see BulkTask). This adds only an
+     * int of space overhead, which is close enough to negligible in
+     * cases where it is not needed to not worry about it.  Because
+     * ForkJoinTask is Serializable, but iterators need not be, we
+     * need to add warning suppressions.

+ * extends Number so that concrete subclasses must publicly do so.
+ */
+abstract class Striped64 extends Number {
+    /*
+     * This class maintains a lazily-initialized table of atomically
+     * updated variables, plus an extra "base" field. The table size
+     * is a power of two. Indexing uses masked per-thread hash codes.
+     * Nearly all declarations in this class are package-private,
+     * accessed directly by subclasses.
+     *
+     * Table entries are of class Cell; a variant of AtomicLong padded
+     * to reduce cache contention on most processors. Padding is
+     * overkill for most Atomics because they are usually irregularly
+     * scattered in memory and thus don't interfere much with each
+     * other. But Atomic objects residing in arrays will tend to be
+     * placed adjacent to each other, and so will most often share
+     * cache lines (with a huge negative performance impact) without
+     * this precaution.
+     *
+     * In part because Cells are relatively large, we avoid creating
+     * them until they are needed.  When there is no contention, all
+     * updates are made to the base field.  Upon first contention (a
+     * failed CAS on base update), the table is initialized to size 2.
+     * The table size is doubled upon further contention until
+     * reaching the nearest power of two greater than or equal to the
+     * number of CPUS. Table slots remain empty (null) until they are
+     * needed.
+     *
+     * A single spinlock ("busy") is used for initializing and
+     * resizing the table, as well as populating slots with new Cells.
+     * There is no need for a blocking lock: When the lock is not
+     * available, threads try other slots (or the base).  During these
+     * retries, there is increased contention and reduced locality,
+     * which is still better than alternatives.
+     *
+     * Per-thread hash codes are initialized to random values.
+     * Contention and/or table collisions are indicated by failed
+     * CASes when performing an update operation (see method
+     * retryUpdate). Upon a collision, if the table size is less than
+     * the capacity, it is doubled in size unless some other thread
+     * holds the lock. If a hashed slot is empty, and lock is
+     * available, a new Cell is created. Otherwise, if the slot
+     * exists, a CAS is tried.  Retries proceed by "double hashing",
+     * using a secondary hash (Marsaglia XorShift) to try to find a
+     * free slot.
+     *
+     * The table size is capped because, when there are more threads
+     * than CPUs, supposing that each thread were bound to a CPU,
+     * there would exist a perfect hash function mapping threads to
+     * slots that eliminates collisions. When we reach capacity, we
+     * search for this mapping by randomly varying the hash codes of
+     * colliding threads.  Because search is random, and collisions
+     * only become known via CAS failures, convergence can be slow,
+     * and because threads are typically not bound to CPUS forever,
+     * may not occur at all. However, despite these limitations,
+     * observed contention rates are typically low in these cases.
+     *
+     * It is possible for a Cell to become unused when threads that
+     * once hashed to it terminate, as well as in the case where
+     * doubling the table causes no thread to hash to it under
+     * expanded mask.  We do not try to detect or remove such cells,
+     * under the assumption that for long-running instances, observed
+     * contention levels will recur, so the cells will eventually be
+     * needed again; and for short-lived ones, it does not matter.

+  # Original source code available here: http://gee.cs.oswego.edu/cgi-bin/viewcvs.cgi/jsr166/src/jsr166e/ConcurrentHashMapV8.java?revision=1.59
+  #
+  # The Ruby port skips out the +TreeBin+ (red-black trees for use in bins
+  # whose size exceeds a threshold).
+  #
+  # A hash table supporting full concurrency of retrievals and
+  # high expected concurrency for updates. However, even though all
+  # operations are thread-safe, retrieval operations do _not_ entail locking,
+  # and there is _not_ any support for locking the entire table
+  # in a way that prevents all access.
+  #
+  # Retrieval operations generally do not block, so may overlap with
+  # update operations. Retrievals reflect the results of the most
+  # recently _completed_ update operations holding upon their
+  # onset. (More formally, an update operation for a given key bears a
+  # _happens-before_ relation with any (non +nil+) retrieval for
+  # that key reporting the updated value.)  For aggregate operations
+  # such as +clear()+, concurrent retrievals may reflect insertion or removal
+  # of only some entries.  Similarly, the +each_pair+ iterator yields elements
+  # reflecting the state of the hash table at some point at or since
+  # the start of the +each_pair+. Bear in mind that the results of
+  # aggregate status methods including +size()+ and +empty?+} are typically
+  # useful only when a map is not undergoing concurrent updates in other
+  # threads. Otherwise the results of these methods reflect transient
+  # states that may be adequate for monitoring or estimation purposes, but not
+  # for program control.
+  #
+  # The table is dynamically expanded when there are too many
+  # collisions (i.e., keys that have distinct hash codes but fall into
+  # the same slot modulo the table size), with the expected average
+  # effect of maintaining roughly two bins per mapping (corresponding
+  # to a 0.75 load factor threshold for resizing). There may be much
+  # variance around this average as mappings are added and removed, but
+  # overall, this maintains a commonly accepted time/space tradeoff for
+  # hash tables.  However, resizing this or any other kind of hash
+  # table may be a relatively slow operation. When possible, it is a
+  # good idea to provide a size estimate as an optional :initial_capacity
+  # initializer argument. An additional optional :load_factor constructor
+  # argument provides a further means of customizing initial table capacity
+  # by specifying the table density to be used in calculating the amount of
+  # space to allocate for the given number of elements. Note that using
+  # many keys with exactly the same +hash+ is a sure way to slow down
+  # performance of any hash table.
+  #
+  # == Design overview
+  #
+  # The primary design goal of this hash table is to maintain
+  # concurrent readability (typically method +[]+, but also
+  # iteration and related methods) while minimizing update
+  # contention. Secondary goals are to keep space consumption about
+  # the same or better than plain +Hash+, and to support high
+  # initial insertion rates on an empty table by many threads.
+  #
+  # Each key-value mapping is held in a +Node+. The validation-based
+  # approach explained below leads to a lot of code sprawl because
+  # retry-control precludes factoring into smaller methods.
+  #
+  # The table is lazily initialized to a power-of-two size upon the
+  # first insertion.  Each bin in the table normally contains a
+  # list of +Node+s (most often, the list has only zero or one +Node+).
+  # Table accesses require volatile/atomic reads, writes, and
+  # CASes. The lists of nodes within bins are always accurately traversable
+  # under volatile reads, so long as lookups check hash code
+  # and non-nullness of value before checking key equality.
+  #
+  # We use the top two bits of +Node+ hash fields for control
+  # purposes -- they are available anyway because of addressing
+  # constraints.  As explained further below, these top bits are
+  # used as follows:
+  #  00 - Normal
+  #  01 - Locked
+  #  11 - Locked and may have a thread waiting for lock
+  #  10 - +Node+ is a forwarding node
+  #
+  # The lower 28 bits of each +Node+'s hash field contain a
+  # the key's hash code, except for forwarding nodes, for which
+  # the lower bits are zero (and so always have hash field == +MOVED+).
+  #
+  # Insertion (via +[]=+ or its variants) of the first node in an
+  # empty bin is performed by just CASing it to the bin.  This is
+  # by far the most common case for put operations under most
+  # key/hash distributions.  Other update operations (insert,
+  # delete, and replace) require locks.  We do not want to waste
+  # the space required to associate a distinct lock object with
+  # each bin, so instead use the first node of a bin list itself as
+  # a lock. Blocking support for these locks relies +Util::CheapLockable.
+  # However, we also need a +try_lock+ construction, so we overlay
+  # these by using bits of the +Node+ hash field for lock control (see above),
+  # and so normally use builtin monitors only for blocking and signalling using
+  # +cheap_wait+/+cheap_broadcast+ constructions. See +Node#try_await_lock+.
+  #
+  # Using the first node of a list as a lock does not by itself
+  # suffice though: When a node is locked, any update must first
+  # validate that it is still the first node after locking it, and
+  # retry if not. Because new nodes are always appended to lists,
+  # once a node is first in a bin, it remains first until deleted
+  # or the bin becomes invalidated (upon resizing).  However,
+  # operations that only conditionally update may inspect nodes
+  # until the point of update. This is a converse of sorts to the
+  # lazy locking technique described by Herlihy & Shavit.
+  #
+  # The main disadvantage of per-bin locks is that other update
+  # operations on other nodes in a bin list protected by the same
+  # lock can stall, for example when user +eql?+ or mapping
+  # functions take a long time.  However, statistically, under
+  # random hash codes, this is not a common problem.  Ideally, the
+  # frequency of nodes in bins follows a Poisson distribution
+  # (http://en.wikipedia.org/wiki/Poisson_distribution) with a
+  # parameter of about 0.5 on average, given the resizing threshold
+  # of 0.75, although with a large variance because of resizing
+  # granularity. Ignoring variance, the expected occurrences of
+  # list size k are (exp(-0.5) * pow(0.5, k) / factorial(k)). The
+  # first values are:
+  #
+  #  0:    0.60653066
+  #  1:    0.30326533
+  #  2:    0.07581633
+  #  3:    0.01263606
+  #  4:    0.00157952
+  #  5:    0.00015795
+  #  6:    0.00001316
+  #  7:    0.00000094
+  #  8:    0.00000006
+  #  more: less than 1 in ten million
+  #
+  # Lock contention probability for two threads accessing distinct
+  # elements is roughly 1 / (8 * #elements) under random hashes.
+  #
+  # The table is resized when occupancy exceeds a percentage
+  # threshold (nominally, 0.75, but see below).  Only a single
+  # thread performs the resize (using field +size_control+, to arrange
+  # exclusion), but the table otherwise remains usable for reads
+  # and updates. Resizing proceeds by transferring bins, one by
+  # one, from the table to the next table.  Because we are using
+  # power-of-two expansion, the elements from each bin must either
+  # stay at same index, or move with a power of two offset. We
+  # eliminate unnecessary node creation by catching cases where old
+  # nodes can be reused because their next fields won't change.  On
+  # average, only about one-sixth of them need cloning when a table
+  # doubles. The nodes they replace will be garbage collectable as
+  # soon as they are no longer referenced by any reader thread that
+  # may be in the midst of concurrently traversing table.  Upon
+  # transfer, the old table bin contains only a special forwarding
+  # node (with hash field +MOVED+) that contains the next table as
+  # its key. On encountering a forwarding node, access and update
+  # operations restart, using the new table.
+  #
+  # Each bin transfer requires its bin lock. However, unlike other
+  # cases, a transfer can skip a bin if it fails to acquire its
+  # lock, and revisit it later. Method +rebuild+ maintains a buffer of
+  # TRANSFER_BUFFER_SIZE bins that have been skipped because of failure
+  # to acquire a lock, and blocks only if none are available
+  # (i.e., only very rarely). The transfer operation must also ensure
+  # that all accessible bins in both the old and new table are usable by
+  # any traversal. When there are no lock acquisition failures, this is
+  # arranged simply by proceeding from the last bin (+table.size - 1+) up
+  # towards the first.  Upon seeing a forwarding node, traversals arrange
+  # to move to the new table without revisiting nodes. However, when any
+  # node is skipped during a transfer, all earlier table bins may have
+  # become visible, so are initialized with a reverse-forwarding node back
+  # to the old table until the new ones are established. (This
+  # sometimes requires transiently locking a forwarding node, which
+  # is possible under the above encoding.) These more expensive
+  # mechanics trigger only when necessary.
+  #
+  # The traversal scheme also applies to partial traversals of
+  # ranges of bins (via an alternate Traverser constructor)
+  # to support partitioned aggregate operations.  Also, read-only
+  # operations give up if ever forwarded to a null table, which
+  # provides support for shutdown-style clearing, which is also not
+  # currently implemented.
+  #
+  # Lazy table initialization minimizes footprint until first use.
+  #
+  # The element count is maintained using a +ThreadSafe::Util::Adder+,
+  # which avoids contention on updates but can encounter cache thrashing
+  # if read too frequently during concurrent access. To avoid reading so
+  # often, resizing is attempted either when a bin lock is
+  # contended, or upon adding to a bin already holding two or more
+  # nodes (checked before adding in the +x_if_absent+ methods, after
+  # adding in others). Under uniform hash distributions, the
+  # probability of this occurring at threshold is around 13%,
+  # meaning that only about 1 in 8 puts check threshold (and after
+  # resizing, many fewer do so). But this approximation has high
+  # variance for small table sizes, so we check on any collision
+  # for sizes <= 64. The bulk putAll operation further reduces
+  # contention by only committing count updates upon these size
+  # checks.

+    # Class holding common representation and mechanics for classes supporting dynamic striping on 64bit values.
+    #
+    # This class maintains a lazily-initialized table of atomically
+    # updated variables, plus an extra +base+ field. The table size
+    # is a power of two. Indexing uses masked per-thread hash codes.
+    # Nearly all methods on this class are private, accessed directly
+    # by subclasses.
+    #
+    # Table entries are of class +Cell+; a variant of AtomicLong padded
+    # to reduce cache contention on most processors. Padding is
+    # overkill for most Atomics because they are usually irregularly
+    # scattered in memory and thus don't interfere much with each
+    # other. But Atomic objects residing in arrays will tend to be
+    # placed adjacent to each other, and so will most often share
+    # cache lines (with a huge negative performance impact) without
+    # this precaution.
+    #
+    # In part because +Cell+s are relatively large, we avoid creating
+    # them until they are needed.  When there is no contention, all
+    # updates are made to the +base+ field.  Upon first contention (a
+    # failed CAS on +base+ update), the table is initialized to size 2.
+    # The table size is doubled upon further contention until
+    # reaching the nearest power of two greater than or equal to the
+    # number of CPUS. Table slots remain empty (+nil+) until they are
+    # needed.
+    #
+    # A single spinlock (+busy+) is used for initializing and
+    # resizing the table, as well as populating slots with new +Cell+s.
+    # There is no need for a blocking lock: When the lock is not
+    # available, threads try other slots (or the base).  During these
+    # retries, there is increased contention and reduced locality,
+    # which is still better than alternatives.
+    #
+    # Per-thread hash codes are initialized to random values.
+    # Contention and/or table collisions are indicated by failed
+    # CASes when performing an update operation (see method
+    # +retry_update+). Upon a collision, if the table size is less than
+    # the capacity, it is doubled in size unless some other thread
+    # holds the lock. If a hashed slot is empty, and lock is
+    # available, a new +Cell+ is created. Otherwise, if the slot
+    # exists, a CAS is tried.  Retries proceed by "double hashing",
+    # using a secondary hash (XorShift) to try to find a
+    # free slot.
+    #
+    # The table size is capped because, when there are more threads
+    # than CPUs, supposing that each thread were bound to a CPU,
+    # there would exist a perfect hash function mapping threads to
+    # slots that eliminates collisions. When we reach capacity, we
+    # search for this mapping by randomly varying the hash codes of
+    # colliding threads.  Because search is random, and collisions
+    # only become known via CAS failures, convergence can be slow,
+    # and because threads are typically not bound to CPUS forever,
+    # may not occur at all. However, despite these limitations,
+    # observed contention rates are typically low in these cases.
+    #
+    # It is possible for a +Cell+ to become unused when threads that
+    # once hashed to it terminate, as well as in the case where
+    # doubling the table causes no thread to hash to it under
+    # expanded mask.  We do not try to detect or remove such cells,
+    # under the assumption that for long-running instances, observed
+    # contention levels will recur, so the cells will eventually be
+    # needed again; and for short-lived ones, it does not matter.

+A pure Ruby gem for reading and writing sound files in Wave format (*.wav).
+
+You can use this gem to create Ruby programs that work with audio, such as [drum machine](http://beatsdrummachine.com). Since it is written in pure Ruby (as opposed to wrapping an existing C library), you can use it without having to compile a separate extension.
+
+For more info, check out the website: <http://wavefilegem.com/>
+
+# Example Usage
+
+This is a short example that shows how to append three separate Wave files into a single file:
+
+    require 'wavefile'
+    include WaveFile
+    
+    FILES_TO_APPEND = ["file1.wav", "file2.wav", "file3.wav"]
+    SAMPLES_PER_BUFFER = 4096
+
+    Writer.new("append.wav", Format.new(:stereo, :pcm_16, 44100)) do |writer|
+      FILES_TO_APPEND.each do |file_name|
+        Reader.new(file_name).each_buffer(SAMPLES_PER_BUFFER) do |buffer|
+          writer.write(buffer)
+        end
+      end
+    end
+
+More examples can be [found on the wiki](https://github.com/jstrait/wavefile/wiki).
+
+
+# Features
+
+* Ability to read and write Wave files with any number of channels in the following formats:
+  * PCM (8, 16, 24, and 32 bits per sample)
+  * Floating Point (32 and 64 bits per sample)
+* Ability to read sample data from a file in any of the supported formats, regardless of the file's actual sample format
+
+            # Sample data will be returned as 32-bit floating point samples,
+            # regardless of the actual sample format in the file.
+            Reader.new("some_file.wav", Format.new(:mono, :float_32, 44100))
+
+* Automatic file management, similar to how `IO.open` works. That is, you can open a file for reading or writing, and if a block is given, the file will automatically be closed when the block exits.
+
+        Writer.new("some_file.wav", Format.new(:mono, :pcm_16, 44100)) do |writer|
+          # write some sample data
+        end
+        # At this point, the writer will automatically be closed, no need to do it manually
+
+* Ability to query metadata about Wave files (sample rate, number of channels, number of sample frames, etc.), including files that are in a format this gem can't read or write.
+* Pure Ruby, so no need to compile a separate extension in order to use it.
+
+
+# Current Release: v0.7.0
+
+Released on March 6, 2016, this version includes these changes:
+
+* The minimum supported Ruby version is now 1.9.3 - earlier versions are no longer supported.
+* New method: `Reader.native_format`. Returns a `Format` instance with information about the underlaying format of the Wave file being read, which is not necessarily the same format the sample data is being converted to as it's being read.
+* `Reader.info()` has been removed. Instead, construct a new `Reader` instance and use `Reader.native_format()` - this will return a `Format` instance with the same info that would have been returned by `Reader.info()`.
+* Similarly, the `Info` class has been removed, due to `Reader.info()` being removed.
+* Constructing a `Reader` instance will no longer raise an exception if the file is valid Wave file, but in a format unsupported by this gem. The purpose of this is to allow calling `Reader.native_format()` on this instance, to get format information for files not supported by this gem.
+* New method: `Reader.readable_format?` returns true if the file is a valid format that the gem can read, false otherwise.
+* `Reader.read()` and `Reader.each_buffer()` will now raise an exception if the file is a valid Wave file, but not a format that the gem can read. Or put differently, if `Reader.readable_format?` returns `false`, any subsequent calls to `Reader.read()` or `Reader.each_buffer()` will raise an exception.
+* Some constants have been made private since they are intended for internal use.
+* Bug fix: Files will now be read/written correctly on big-endian platforms. Or in other words, sample data is always read as little-endian, regardless of the native endianness of the platform.
+
+
+# Compatibility
+
+WaveFile has been tested with these Ruby versions, and appears to be compatible with them:
+
+* MRI 2.3, 2.2, 2.1, 2.0, 1.9.3
+
+1.9.3 is the minimum supported Ruby version.
+
+If you find any compatibility issues, please let me know by opening a GitHub issue.
+
+
+# Dependencies
+
+WaveFile has no external dependencies. It is written in pure Ruby, and is entirely self-contained.
+
+
+# Installation
+
+First, install the WaveFile gem from rubygems.org:
+
+    gem install wavefile
+
+...and include it in your Ruby program:
+
+    require 'wavefile'
+
+Note that if you're installing the gem into the default Ruby that comes pre-installed on MacOS (as opposed to a Ruby installed via [RVM](http://rvm.io/) or [rbenv](https://github.com/sstephenson/rbenv/)), you should used `sudo gem install wavefile`. Otherwise you might run into a file permission error.

+# WebSocket Ruby
+
+- Travis CI build: [![](https://travis-ci.org/imanel/websocket-ruby.png)](http://travis-ci.org/imanel/websocket-ruby)
+- Autobahn tests: [server](http://imanel.github.com/websocket-ruby/autobahn/server/), [client](http://imanel.github.com/websocket-ruby/autobahn/client/)
+
+Universal Ruby library to handle WebSocket protocol. It focuses on providing abstraction layer over [WebSocket API](http://dev.w3.org/html5/websockets/) instead of providing server or client functionality.
+
+Currently WebSocket Ruby supports all existing drafts of WebSocket, which include:
+
+- [hixie-75](http://tools.ietf.org/html/draft-hixie-thewebsocketprotocol-75)
+- [hixie-76](http://tools.ietf.org/html/draft-hixie-thewebsocketprotocol-76)
+- [all hybi drafts (00-13)](http://tools.ietf.org/html/draft-ietf-hybi-thewebsocketprotocol-17)
+- [RFC 6455](http://datatracker.ietf.org/doc/rfc6455/)
+
+## Installation
+
+WebSocket Ruby has no external dependencies, so it can be installed from source or directly from rubygems:
+
+```
+gem install "websocket"
+```
+
+or via Gemfile:
+
+```
+gem "websocket"
+```
+
+## Server handshake
+
+``` ruby
+ at handshake = WebSocket::Handshake::Server.new
+
+# Parse client request
+ at handshake << <<EOF
+GET /demo HTTP/1.1\r
+Upgrade: websocket\r
+Connection: Upgrade\r
+Host: example.com\r
+Sec-WebSocket-Origin: http://example.com\r
+Sec-WebSocket-Version: 13\r
+Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ==\r
+\r
+EOF
+
+# All data received?
+ at handshake.finished?
+
+# No parsing errors?
+ at handshake.valid?
+
+# Create response
+ at handshake.to_s # HTTP/1.1 101 Switching Protocols
+                # Upgrade: websocket
+                # Connection: Upgrade
+                # Sec-WebSocket-Accept: s3pPLMBiTxaQ9kYGzzhZRbK+xOo=
+```
+
+## Client handshake
+
+``` ruby
+ at handshake = WebSocket::Handshake::Client.new(:url => 'ws://example.com')
+
+# Create request
+ at handshake.to_s # GET /demo HTTP/1.1
+                # Upgrade: websocket
+                # Connection: Upgrade
+                # Host: example.com
+                # Sec-WebSocket-Origin: http://example.com
+                # Sec-WebSocket-Version: 13
+                # Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ==
+
+# Parse server response
+ at handshake << <<EOF
+HTTP/1.1 101 Switching Protocols\r
+Upgrade: websocket\r
+Connection: Upgrade\r
+Sec-WebSocket-Accept: s3pPLMBiTxaQ9kYGzzhZRbK+xOo=\r
+\r
+EOF
+
+# All data received?
+ at handshake.finished?
+
+# No parsing errors?
+ at handshake.valid?
+```
+
+## Parsing and constructing frames
+
+``` ruby
+# Prepare frame for sending
+frame = WebSocket::Frame::Outgoing::Server.new(:version => @handshake.version, :data => "Hello", :type => :text)
+frame.to_s # "\x81\x05\x48\x65\x6c\x6c\x6f"
+
+# Parse incoming frames
+frame = WebSocket::Frame::Incoming::Server.new(:version => @handshake.version)
+frame << "\x81\x05\x48\x65\x6c\x6c\x6f\x81\x06\x77\x6f\x72\x6c\x64\x21"
+frame.next # "Hello"
+frame.next # "world!""
+```
+
+## Examples & Projects using WebSocket-Ruby
+
+- [WebSocket-EventMachine-Client](https://github.com/imanel/websocket-eventmachine-client) - client based on EventMachine
+- [WebSocket-EventMachine-Server](https://github.com/imanel/websocket-eventmachine-server) - server based on EventMachine (drop-in replacement for EM-WebSocket)
+- [Selenium-WebDriver](https://rubygems.org/gems/selenium-webdriver) - tool for writing automated tests of websites
+- [Rubame](https://github.com/saward/Rubame) - websocket game server
+
+## Native extension
+
+WebSocket gem is written in pure Ruby, without any dependencies or native extensions and still is one of the fastest implementations of WebSocket API. However, if you want to increase it's speed even further, I created additional gem with dedicated native extensions for both C and Java. Those extensions provide 20-30% increase in speed(more accurate comparison can be found in autobahn test results)
+
+In order to use native extension just install [websocket-native](http://github.com/imanel/websocket-ruby-native) gem or add it to Gemfile - WebSocket will automatically detect and load it.

+## Bitcrusher
 
 ### Key:
-  :reverb
+  :bitcrusher
 
 ### Doc:
-  Please write documentation!
+  Creates lo-fi output by decimating and deconstructing the incoming audio by lowering both the sample rate and bit depth. The default sample rate for CD audio is 44100, so use values less than that for that crunchy chip-tune sound full of artefacts and bitty distortion. Similarly, the default bit depth for CD audio is 16, so use values less than that for lo-fi sound.
 
-### Arguments:
+### Opts:
+  * amp:
+    - doc: The amplitude of the sound. Typically a value between 0 and 1. Higher amplitudes may be used, but won't make the sound louder, they will just reduce the quality of all the sounds currently being played (due to compression.)
+    - default: 1
+    - constraints: must be zero or greater
+    - May be changed whilst playing
+    - Has slide parameters for shaping changes
   * mix:
-    - doc: write me
-    - default: 0.4
-    - constraints: none
-    - Can not be changed once set
-
-  * mix_slide:
-    - doc: write me
+    - doc: The amount (percentage) of FX present in the resulting sound represented as a value between 0 and 1. For example, a mix of 0 means that only the original sound is heard, a mix of 1 means that only the FX is heard (typically the default) and a mix of 0.5 means that half the original and half of the FX is heard.
+    - default: 1
+    - constraints: must be a value between 0 and 1 inclusively
+    - May be changed whilst playing
+    - Has slide parameters for shaping changes
+  * pre_amp:
+    - doc: Amplification applied to the input signal immediately before it is passed to the FX.
+    - default: 1
+    - constraints: must be zero or greater
+    - May be changed whilst playing
+    - Has slide parameters for shaping changes
+  * sample_rate:
+    - doc: The sample rate the audio will be resampled at. This represents the number of times per second the audio is sampled. The higher the sample rate, the closer to the original the sound will be, the lower the more low-fi it will sound. The highest sample rate is 44100 (full quality) and the lowest is ~100 (extremely low quality). Try values in between such as 1000, 3000, 8000...

+    - constraints: must be greater than zero
+    - May be changed whilst playing
+    - Has slide parameters for shaping changes
+  * bits:
+    - doc: The bit depth of the resampled audio. Lower bit depths make the audio sound grainy and less defined. The highest bit depth is 16 (full quality) and the lowest is 1 (lowest quality).
+    - default: 8
+    - constraints: must be greater than zero
+    - May be changed whilst playing
+    - Has slide parameters for shaping changes
+  * cutoff:
+    - doc: MIDI note representing the highest frequencies allowed to be present in the sound. A low value like 30 makes the sound round and dull, a high value like 100 makes the sound buzzy and crispy.
     - default: 0
-    - constraints: none
-    - Can not be changed once set
+    - constraints: must be zero or greater,must be a value less than 131

 ### Doc:
-  Please write documentation!
+  Amplitude modifier. All FX have their own amp built in, so it may be the case that you don't specifically need an isolated amp FX. However, it is useful to be able to control the overall amplitude of a number of running synths. All sounds created in the FX block will have their amplitudes multipled by the amp level of this FX. For example, use an amp of 0 to silence all internal synths.
 
-### Arguments:

-## Simple Modulated Triangle Wave
+## Basic FM synthesis with frequency modulation.
 
 ### Key:
-  :mod_tri_s
+  :mod_fm
 
 ### Doc:
-  
+  The FM synth modulating between two notes - the duration of the modulation can be modified using the mod_phase arg, the range (number of notes jumped between) by the mod_range arg and the width of the jumps by the mod_width param. The FM synth is a sine wave with a fundamental frequency which is modulated at audio rate by another sine wave with a specific modulation, division and depth. Useful for generating a wide range of sounds by playing with the `:divisor` and `:depth` params. Great for deep powerful bass and crazy 70s sci-fi sounds.

-## The Prophet
+## Modulated Pulse
 
 ### Key:
-  :prophet
+  :mod_pulse
 
 ### Doc:
-  Dark and swirly, this synth uses Pulse Width Modulation
-      (PWM) to create a timbre which continually moves around. This
-      effect is created using the pulse ugen which produces a variable
-      width square wave. We then control the width of the pulses using a
-      variety of LFOs - sin-osc and lf-tri in this case. We use a number
-      of these LFO modulated pulse ugens with varying LFO type and rate
-      (and phase in some cases) to provide the LFO with a different
-      starting point. We then mix all these pulses together to create a
-      thick sound and then feed it through a resonant low pass filter
-      (rlpf).
-
-      For extra bass, one of the pulses is an octave lower (half the
-      frequency) and its LFO has a little bit of randomisation thrown
-      into its frequency component for that extra bit of variety.
-
-### Arguments:
+  A pulse wave with a low pass filter modulating between two notes via a variety of control waves (see mod_wave: arg). The pulse wave defaults to a square wave, but the timbre can be changed dramatically by adjusting the pulse_width arg between 0 and 1.

+## The Prophet
+
+### Key:
+  :prophet
+
+### Doc:
+  Dark and swirly, this synth uses Pulse Width Modulation (PWM) to create a timbre which continually moves around. This effect is created using the pulse ugen which produces a variable width square wave. We then control the width of the pulses using a variety of LFOs - sin-osc and lf-tri in this case. We use a number of these LFO modulated pulse ugens with varying LFO type and rate (and phase in some cases) to provide the LFO with a different starting point. We then mix all these pulses together to create a thick sound and then feed it through a resonant low pass filter (rlpf). For extra bass, one of the pulses is an octave lower (half the frequency) and its LFO has a little bit of randomisation thrown into its frequency component for that extra bit of variety.

Useful for ensuring the containing signal doesn't overwhelm other aspects of the sound. Also a general purpose hard-knee dynamic range processor which can be tuned via the opts to both expand and compress the signal.

+3.7 Sample Packs
+
+# Sample Packs
+
+**Note: this section of the tutorial covers the advanced topic of
+working with large directories of your own samples. This will be the
+case if you've downloaded or bought your own sample packs and wish to
+use them within Sonic Pi.**
+
+**Feel free to skip this if you're happy working with the built-in
+samples.**
+
+When working with large folders of external samples it can be cumbersome
+to have to type the whole path every time to trigger an individual
+sample.
+
+For example, say you have the following folder on your machine:
+
+```
+/path/to/my/samples/
+```
+
+When we look inside that folder we find the following samples:
+
+* `100_A#_melody1.wav`
+* `100_A#_melody2.wav`
+* `100_A#_melody3.wav`
+* `120_A#_melody4.wav`
+* `120_Bb_guit1.wav`
+* `120_Bb_piano1.wav`
+
+Typically in order to play the piano sample we can use the full path:
+
+```
+sample "/path/to/my/samples/120_Bb_piano1.wav"
+```
+
+If we want to then play the guitar sample we can use its full path too:
+
+```
+sample "/path/to/my/samples/120_Bb_guit.wav"
+```
+
+However, both of these calls to sample requires us to *know* the names
+of the samples within our directory. What if we just want to listen to
+each sample in turn quickly? 
+
+## Indexing Sample Packs
+
+If we want to play the first sample in a directory we just need to pass
+the directory's name to `sample` and the index `0` as follows:
+
+```
+sample "/path/to/my/samples/", 0
+```
+
+We can even make a shortcut to our directory path using a variable:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, 0
+```
+
+Now, if we want to play the second sample in our directory, we just need
+to add 1 to our index:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, 1
+```
+
+Notice that we no longer need to know the names of the samples in the
+directory - we just need to know the directory itself (or have a
+shortcut to it). If we ask for an index which is larger than the number
+of samples, it simply wraps round just like Rings. Therefore, whatever
+number we use we're guaranteed to get one of the samples in that
+directory.
+
+## Filtering Sample Packs
+
+Usually indexing is enough, but sometimes we need more power to sort
+and organise our samples. Luckily many sample packs add useful
+information in the filenames. Let's take another look at the sample file
+names in our directory:
+
+* `100_A#_melody1.wav`
+* `100_A#_melody2.wav`
+* `100_A#_melody3.wav`
+* `120_A#_melody4.wav`
+* `120_Bb_guit1.wav`
+* `120_Bb_piano1.wav`
+
+Notice that in these filenames we have quite a bit of
+information. Firstly, we have the BPM of the sample (beats per minute)
+at the start. So, the piano sample is at 120 BPM and our first three
+melodies are at 100 BPM. Also, our sample names contain the key. So the
+guitar sample is in Bb and the melodies are in A#. This information is
+very useful for mixing in these samples with our other code. For
+example, we know we can only play the piano sample with code that's in
+120 BPM and in the key of Bb.
+
+It turns out that we can use this particular naming convention of our
+sample sets in the code to help us filter out the ones we want. For
+example, if we're working at 120 BPM, we can filter down to all the
+samples that contain the string `"120"` with the following:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120"
+```
+
+This will play us the first match. If we want the second match we just
+need to use the index:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120", 1
+```
+
+We can even use multiple filters at the same time. For example, if we
+want a sample whose filename contains both the substrings "120" and "A#"
+we can find it easily with the following code:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120", "A#"
+```
+
+Finally, we're still free to add our usual opts to the call to `sample`:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120", "Bb", 1, lpf: 70, amp: 2
+```
+
+## Sources
+
+The sample filter pre-arg system understands two types of information:
+sources and filters. Sources are information used to create the list of
+potential candidates. A source can take two forms:
+
+1. "/path/to/samples" - a string representing a valid path to a directory 
+2. "/path/to/samples/foo.wav" - a string representing a valid path to a sample
+
+The `sample` fn will first gather all sources and use them to create a
+large list of candidates. This list is constructed by first adding all
+valid paths and then by adding all the valid `.flac`, `.aif`, `.aiff`,
+`.wav`, `.wave` files contained within the directories.
+
+For example, take a look at the following code:
+
+```
+samps = "/path/to/my/samples/"
+samps2 = "/path/to/my/samples2/"
+path = "/path/to/my/samples3/foo.wav"
+
+sample samps, samps2, path, 0
+```
+
+Here, we're combining the contents of the samples within two directories
+and adding a specific sample. If `"/path/to/my/samples/"` contained 3
+samples and `"/path/to/my/samples2/"` contained 12, we'd have 16
+potential samples to index and filter (3 + 12 + 1).
+
+By default, only the sample files within a directory are gathered into
+the candidate list. Sometimes you might have a number of nested folders of
+samples you wish to search and filter within. You can therefore do a
+recursive search for all samples within all subfolders of a particular
+folder by adding `**` to the end of the path:
+
+```
+samps = "/path/to/nested/samples/**"
+sample samps, 0
+```
+
+Take care though as searching through a very large set of folders may
+take a long time. However, the contents of all folder sources are
+cached, so the delay will only happen the first time.
+
+Finally, note that the sources *must go first*. If no source is given,
+then the set of built-in samples will be selected as the default list of
+candidates to work with:
+
+## Filters
+
+Once you have a list of candidates you may use the following filtering
+types to further reduce the selection:
+
+* `"foo"` Strings will filter on substring occurrence within file name (minus directory path and extension).
+* `/fo[oO]/` Regular Expressions will filter on pattern matching of file name (minus directory path and extension).
+* `:foo` - Keywords will filter candidates on whether the keyword is a direct match of the filename (minus directory path and extension).
+* `lambda{|a| ... }` - Procs with one argument will be treated as a candidate filter or generator function. It will be passed the list of current candidates and must return a new list of candidates (a list of valid paths to sample files).
+* `1` - Numbers will select the candidate with that index (wrapping round like a ring if necessary).
+
+For example, we can filter over all the samples in a directory
+containing the string \"foo\" and play the first matching sample at half
+speed:
+
+```
+sample \"/path/to/samples\", \"foo\", rate: 0.5
+```
+
+See the help for `sample` for many detailed usage examples. Note that
+the ordering of the filters is honoured.
+
+## Composites
+
+Finally, you may use lists wherever you may place a source or
+filter. The list will be automatically flattened and the contents will
+be treated as regular sources and filters. Therefore the following calls
+to `sample` are semantically equivalent:
+
+```
+sample "/path/to/dir", "100", "C#"
+sample ["/path/to/dir", "100", "C#"]
+sample "/path/to/dir", ["100", "C#"]
+sample ["/path/to/dir", ["100", ["C#"]]]
+```
+
+## Wrapping Up
+
+This was an advanced section for people that need real power to
+manipulate and use sample packs. If most of this section didn't make too
+much sense, don't worry. It's likely you don't need any of this
+functionality just yet. However, you'll know when you do need it and you
+can come back and re-read this when you start working with large
+directories of samples.

+A.9 Randomisation
+
+# Surfing Random Streams
+
+Back in episode 4 of this tutorial series we took a brief look at
+randomisation whilst coding up some sizzling synth riffs. Given that
+randomisation is such an important part of my live coding DJ sets I
+thought it would be useful to cover the fundamentals in much greater
+detail. So, get your lucky hat on and let's surf some random streams!
+
+# There is no random
+
+The first thing to learn which might really surprise you when playing
+with Sonic Pi's randomisation functions is that they're not actually
+really random. What does this actually mean? Well, let's try a couple of
+tests. First, imagine a number in your head between 0 and 1. Keep it
+there and don't tell me. Now let me guess... was it `0.321567`? No? Bah,
+I'm clearly no good at this. Let me have another go, but let's ask Sonic
+Pi to choose a number this time. Fire up Sonic Pi v2.7+ and ask it for a
+random number but again don't tell me:
+
+    print rand
+    
+Now for the reveal... was it `0.75006103515625`? Yes! Ha, I can see
+you're a little sceptical. Perhaps it was just a lucky guess. Let's try
+again. Press the Run button again and see what we get... What?
+`0.75006103515625` again? This clearly can't be random! You're right,
+it's not.
+
+What's going on here? The fancy computer science word here is
+determinism. This just means that nothing is by chance and everything is
+destined to be. Your version of Sonic Pi is destined to always return
+`0.75006103515625` in the program above. This might sound pretty
+useless, but let me assure you that it's one of the most powerful parts
+of Sonic Pi. If you stick at it you'll learn how to rely on the
+deterministic nature of Sonic Pi's randomisation as a fundamental
+building block for your compositions and live coded DJ sets.
+
+# A Random Melody
+
+When Sonic Pi boots it actually loads into memory a sequence of 441,000
+pre-generated random values. When you call a random function such as
+`rand` or `rrand`, this random stream is used to generate your
+result. Each call to a random function consumes a value from this
+stream. Therefore the 10th call to a random function will use the 10th
+value from the stream. Also, every time you press the Run button, the
+stream is reset for that run. This is why I could predict the result to
+`rand` and why the 'random' melody was the same every time. Everybody's
+version of Sonic Pi uses the exact same random stream which is very
+important when we start sharing our pieces with each other. 
+
+Let's use this knowledge to generate a repeatable random melody:
+
+    8.times do
+     play rrand_i(50, 95)
+     sleep 0.125
+    end
+
+Type this into a spare buffer and hit Run. You'll hear a melody
+consisting of 'random' notes between 50 and 95. When it's finished, hit
+Run again to hear exactly the same melody again.
+
+*start breakout box*
+## Handy Randomisation Functions
+ Sonic Pi comes with a number of useful functions for working with the
+random stream. Here's a list of some of the most useful:
+
+* `rand` - Simply returns the next value in the random stream
+* `rrand` - Returns a random value within a range
+* `rrand_i` - Returns a random whole number within a range
+* `one_in` - Returns true or false with the given probability
+* `dice` - Imitates rolling a dice and returns a value between 1 and 6
+* `choose` - Chooses a random value from a list
+
+Check out their documentation in the Help system for detailed
+information and examples.
+
+ *end breakout box*
+
+# Resetting the Stream
+
+Whilst the ability to repeat a sequence of chosen notes is essential to
+allow you to replay a riff on the dance floor, it might not be exactly
+the riff you want. Wouldn't it be great if we could try a number of
+different riffs and choose the one we liked best? This is where the real
+magic starts.
+
+We can manually set the stream with the fn `use_random_seed`. In
+Computer Science, a random seed is the starting point from which a new
+stream of random values can sprout out and blossom. Let's try it:
+
+    use_random_seed 0
+    3.times do
+      play rrand_i(50, 95)
+      sleep 0.125
+    end
+    
+Great, we get the first three notes of our random melody above: `84`,
+`83` and `71`. However, we can now change the seed to something
+else. How about this:
+
+    use_random_seed 1
+    3.times do
+      play rrand_i(50, 95)
+      sleep 0.125
+    end
+    
+    
+Interesting, we get `83`, `71` and `61` . You might notice that the
+first two numbers here are the same as the last two numbers before -
+this isn't a coincidence.
+
+Remember that the random stream is just a giant list of 'pre-rolled'
+values. Using a random seed simply jumps us to a point in that
+list. Another way of thinking about it is to imagine a huge deck of
+pre-shuffled cards. Using a random seed is cutting the deck at a
+particular point. The fabulous part of this is that it's precisely this
+ability to jump around the random stream which gives us huge power when making
+music.
+
+Let's revisit our random melody of 8 notes with this new stream
+resetting power, but let's also throw in a live loop so we can
+experiment live whilst it's playing:
+
+    live_loop :random_riff do    
+      use_random_seed 0
+      8.times do
+        play rrand_i(50, 95), release: 0.1
+        sleep 0.125
+      end
+    end
+
+Now, whilst it's still playing, change the seed value from `0` to
+something else. Try `100`, what about `999`. Try your own values,
+experiment and play around - see which seed generates the riff you like
+best.
+
+# Bringing it all together
+
+This month's tutorial has been quite a technical dive into the workings
+of Sonic Pi's randomisation functionality. Hopefully it has given you
+some insight into how it works and how you can start using randomisation
+in a reliable way to create repeatable patterns within your music. It's
+important to stress that you can use repeatable randomisation *anywhere*
+you want. For example, you can randomise the amplitude of notes, the
+timing of the rhythm, the amount of reverb, the current synth, the mix
+of an FX, etc. etc. In the future we'll take a close look at some of
+these applications, but for now let me leave you with a short example.
+
+Type the following into a spare buffer, hit Run, and then start changing
+the seeds around, hit Run again (whilst it's still playing) and explore
+the different sounds, rhythms and melodies you can make. When you find a
+nice one, remember the seed number so you can get back to it. Finally,
+when you've found a few seeds you like, put on a live coded performance
+for your friends by simply switching between your favourite seeds to
+create a full piece.

+A.10 Control
+
+# Controlling Your Sound
+
+So far during this series we've focussed on triggering sounds. We've
+discovered that we can trigger the many synths built into Sonic Pi with
+`play` or `synth` and how to trigger pre-recorded samples with
+`sample`. We've also looked at how we can wrap these triggered sounds
+within studio FX such as reverb and distortion using the `with_fx`
+command. Combine this with Sonic Pi's incredibly accurate timing system
+and you can produce a vast array of sounds, beats and riffs. However,
+once you've carefully selected a particular sound's options and
+triggered it, there's no ability to mess with it whilst it's playing
+right? Wrong! Today you're going to learn something very powerful - how
+to control running synths.
+
+## A Basic Sound
+
+Let's create a nice simple sound. Fire up Sonic Pi and in a fresh buffer
+type the following:
+
+```
+synth :prophet, note: :e1, release: 8, cutoff: 100
+```
+
+Now press the Run button at the top left to hear a lovely rumbling synth
+sound. Go ahead, press it again a few times to get a feel for it. OK,
+done? Let's start controlling it!
+
+
+## Synth Nodes
+
+A little known feature in Sonic Pi is that the fns `play`, `synth` and
+`sample`, return something called a `SynthNode` which represents a
+running sound. You can capture one of these `SynthNode`s using a
+standard variable and then **control** it at a later point in time. For
+example, let's change the value of the `cutoff:` opt after 1 beat:
+
+```
+sn = synth :prophet, note: :e1, release: 8, cutoff: 100
+sleep 1
+control sn, cutoff: 130
+```
+
+Let's look at each line in turn: 
+
+Firstly we trigger the `:prophet` synth using the `synth` fn as
+normal. However we also capture the result in a variable called `sn`. We
+could have called this variable something completely different such as
+`synth_node` or `jane` - the name doesn't matter. However, it's
+important to choose a name that's meaningful to you for your
+performances and for people reading your code. I chose `sn` as it's a nice
+short mnemonic for synth node.
+
+On line 2 we have a standard `sleep` command. This does nothing special
+- it just asks the computer to wait for 1 beat before moving onto the
+next line.
+
+Line 3 is where the control fun starts. Here, we use the `control` fn to
+tell our running `SynthNode` to change the cutoff value to `130`. If you
+hit the **Run** button, you'll hear the `:prophet` synth start playing
+as before, but after 1 beat it will shift to sound a lot brighter.
+
+
+** Breakout Box Start **
+Modulatable Options
+
+Most of Sonic Pi's synths and FX opts may be changed after being
+triggered. However, this isn't the case for all of them. For example,
+the envelope opts `attack:`, `decay:`, `sustain:` and `release:` can
+only be set when triggering the synth. Figuring out which opts can and
+can't be changed is simple - just head to the documentation for a given
+synth or FX and then scroll down to the individual option documentation
+and look for the phrases "May be changed whilst playing" or "Can not be
+changed once set". For example, the documentation for the `:beep`
+synth's `attack:` opt makes it clear that it's not possible to change
+it:
+
+* Default: 0 
+* Must be zero or greater 
+* Can not be changed once set 
+* Scaled with current BPM value 
+** Breakout Box End **
+
+## Multiple Changes
+
+Whilst a synth is running you're not limited to changing it only once -
+you're free to change it as many times as you like. For example, we can
+turn our `:prophet` into a mini arpeggiator with the following:
+
+```
+notes = (scale :e3, :minor_pentatonic)
+sn = synth :prophet, note: :e1, release: 8, cutoff: 100
+sleep 1
+16.times do
+  control sn, note: notes.tick
+  sleep 0.125
+end
+```
+
+In this snippet of code we just added a couple of extra things. First we
+defined a new variable called `notes` which contains the notes we'd like
+to cycle through (an arpeggiator is just a fancy name for something that
+cycles through a list of notes in order). Secondly we replaced our
+single call to `control` with an iteration calling it 16 times. In each
+call to `control` we `.tick` through our ring of `notes` which will
+automatically repeat once we get to the end (thanks to the fabulous power
+of Sonic Pi's rings). For a bit of variety try replacing `.tick` with
+`.choose` and see if you can hear the difference.
+
+Note that we can change multiple opts simultaneously. Try changing the
+control line to the following and listen for the difference:
+
+```
+control sn, note: notes.tick, cutoff: rrand(70, 130)
+```
+
+## Sliding 
+
+When we control a `SynthNode`, it responds exactly on time and instantly
+changes the value of the opt to the new one as if you'd pressed a button
+or flicked a switch requesting the change. This can sound rhythmical and percussive -
+especially if the opt controls an aspect of the timbre such as
+`cutoff:`. However, sometimes you don't want the change to happen
+instantaneously. Instead, you might want to smoothly move from the
+current value to the new one as if you'd moved a slider or dial. Of
+course, Sonic Pi can also do this too using the `_slide:` opts.
+
+Each opt that can be modified also has a special corresponding `_slide:`
+opt that allows you to specify a slide time. For example, `amp:` has
+`amp_slide:` and `cutoff:` has `cutoff_slide:`. These slide opts work
+slightly differently than all the other opts in that they tell the synth
+note how to behave **next time they are controlled**. Let's take a look:
+
+```
+sn = synth :prophet, note: :e1, release: 8, cutoff: 70, cutoff_slide: 2
+sleep 1
+control sn, cutoff: 130
+```
+
+Notice how this example is exactly the same as before except with the
+addition of `cutoff_slide:`. This is saying that next time this synth
+has its `cutoff:` opt controlled, it will take 2 beats to slide from the
+current value to the new one. Therefore, when we use `control` you can
+hear the cutoff slide from 70 to 130. It creates an interesting dynamic
+feel to the sound. Now, try changing the `cutoff_slide:` time to a
+shorter value such as 0.5 or a longer value such as 4 to see how it
+changes the sound. Remember, you can slide any of the modifiable opts in
+exactly this way and each `_slide:` value can be totally different so
+you can have the cutoff sliding slowly, the amp sliding fast and the pan
+sliding somewhere in between if that's what you're looking to create...
+
+
+## Bringing it all together
+
+Let's look at a short example which demonstrates the power of
+controlling synths after they've been triggered. Notice that you can
+also slide FX just like synths although with a slightly different
+syntax. Check out section 7.2 of the built-in tutorial for more
+information on controlling FX.
+
+Copy the code into a spare buffer and take a listen. Don't stop there
+though - play around with the code. Change the slide times, change the
+notes, the synth, the FX and the sleep times and see if you can turn it
+into something completely different!
+
+
+```
+live_loop :moon_rise do
+  with_fx :echo, mix: 0, mix_slide: 8 do |fx|
+    control fx, mix: 1
+    notes = (scale :e3, :minor_pentatonic, num_octaves: 2).shuffle
+    sn = synth :prophet , sustain: 8, note: :e1, cutoff: 70, cutoff_slide: 8
+    control sn, cutoff: 130
+    sleep 2
+    32.times do
+      control sn, note: notes.tick, pan: rrand(-1, 1)
+      sleep 0.125
+    end
+  end
+end
+```

+A.11 Tick Tock
+
+# Tracking the Beat
+
+Last month in this series we took a deep technical dive into the
+randomisation system underpinning Sonic Pi. We explored how we can use
+it to deterministically add new levels of dynamic control over our
+code. This month we're going to continue our technical dive and turn our
+attention to Sonic Pi's unique tick system. By the end of this article
+you'll be ticking your way through rhythms and riffs on your way to
+being a live coding DJ.
+
+
+# Beat Counting
+
+When making music we often want to do a different thing depending on
+which beat it is. Sonic Pi has a special beat counting system called
+`tick` to give you precise control over when a beat actually occurs and
+even supports multiple beats with their own tempos. 
+
+Let's have a play - to advance the beat we just need to call
+`tick`. Open up a fresh buffer, type in the following and hit Run:
+
+```
+puts tick #=> 0
+```
+
+This will return the current beat: `0`. Notice that even if you press
+the Run button a few times it will always return `0`. This is because
+each run starts a fresh beat counting from 0.  However, whilst the run
+is still active, we can advance the beat as many times as we want:
+
+```
+puts tick #=> 0
+puts tick #=> 1
+puts tick #=> 2
+```
+
+<breakout> Whenever you see the symbol `#=>` at the end of a line of
+code it means that that line will log the text on the
+right-hand-side. For example, `puts foo #=> 0` means the code `puts foo`
+prints `0` to the log at that point in the program.  </breakout>
+
+# Checking the Beat
+
+We've seen that `tick` does two things. It increments (adds one)
+and returns the current beat. Sometimes we just want to look at the
+current beat without having to increment it which we can do via `look`:
+
+``` 
+puts tick #=> 0
+puts tick #=> 1
+puts look #=> 1
+puts look #=> 1
+``` 
+
+In this code we tick the beat up twice and then call `look` twice. We'll
+see the following values in the log: `0`, `1`, `1`, `1`. The first two
+`tick`s returned `0`, then `1` as expected, then the two `look`s just
+returned the last beat value twice which was `1`. 
+
+
+# Rings
+
+So now we can advance the beat with `tick` and check the beat with
+`look`. What next? We need something to tick over. Sonic Pi uses rings
+for representing riffs, melodies and rhythms and the tick system has
+been specifically designed to work very closely with them. In fact,
+rings have their own dot version of `tick` which does two things. Firstly,
+it acts like a regular tick and increments the beat. Secondly it looks
+up the ring value using the beat as the index. Let's take a look:
+
+```
+puts (ring :a, :b, :c).tick #=> :a
+```
+
+`.tick` is a special dot version of `tick` which will return the first
+value of the ring `:a`. We can grab each of the values in the ring by
+calling `.tick` multiple times:
+
+```
+puts (ring :a, :b, :c).tick #=> :a
+puts (ring :a, :b, :c).tick #=> :b
+puts (ring :a, :b, :c).tick #=> :c
+puts (ring :a, :b, :c).tick #=> :a
+puts look                   #=> 3
+```
+
+Take a look at the log and you'll see `:a`, `:b`, `:c` and then `:a`
+again. Notice that `look` returns `3`. Calls to `.tick` act just like
+they are regular calls to `tick` - they increment the local beat.
+
+
+# A Live Loop Arpeggiator 
+
+The real power comes when you mix `tick` with rings and
+`live_loop`s. When combined we have all the tools we need to both build
+and understand a simple arpegiator. We need just four things:
+
+1. A ring containing the notes we want to loop over.
+2. A means of incrementing and obtaining the beat. 
+3. The ability to play a note based on the current beat.
+4. A loop structure to keep the arpegiator repeating.
+
+These concepts can all be found in the following code:
+
+```
+notes = (ring 57, 62, 55, 59, 64)
+
+live_loop :arp do
+  use_synth :dpulse
+  play notes.tick, release: 0.2
+  sleep 0.125
+end
+```
+
+Let's look at each of these lines. First we define our ring of notes
+which we'll continually play. We then create a `live_loop` called `:arp`
+which loops round for us. Each time round the `live_loop` we set our
+synth to `:dpulse` and then play the next note in our ring using
+`.tick`. Remember that this will increment our beat counter and use the
+latest beat value as an index into our notes ring. Finally, we wait for
+an eighth of a beat before looping round again.
+
+# Multiple Simultaneous Beats
+
+A really important thing to know is that `tick`s are local to the
+`live_loop`. This means that each `live_loop` has its own independent
+beat counter. This is much more powerful than having a global metronome
+and beat. Let's take a look at this in action:
+
+notes = (ring 57, 62, 55, 59, 64)
+
+with_fx :reverb do
+  live_loop :arp do
+    use_synth :dpulse
+    play notes.tick + 12, release: 0.1
+    sleep 0.125
+  end
+end
+
+live_loop :arp2 do
+  use_synth :dsaw
+  play notes.tick - 12, release: 0.2
+  sleep 0.75
+end
+
+# Clashing Beats
+
+A big cause of confusion with Sonic Pi's tick system is when people want
+to tick over multiple rings in the same `live_loop`:
+
+use_bpm 300
+use_synth :blade
+live_loop :foo do
+  play (ring :e1, :e2, :e3).tick
+  play (scale :e3, :minor_pentatonic).tick
+  sleep 1
+end
+
+Even though each `live_loop` has its own independent beat counter, we're
+calling `.tick` twice within the same `live_loop`. This means that the
+beat will be incremented twice every time round. This can produce some
+interesting polyrhythms but is often not what you want. There are two
+solutions to this problem. One option is to manually call `tick` at the
+start of the `live_loop` and then use `.look` to look up the current
+beat in each `live_loop`. The second solution is to pass a unique name
+to each call to `.tick` such as `.tick(:foo)`. Sonic Pi will then create
+and track a separate beat counter for each named tick you use. That way
+you can work with as many beats as you need! See the section on named
+ticks in 9.4 of the built-in tutorial for more information.
+
+# Bringing it all together
+
+Let's bring all this knowledge of `tick`s, `ring`s and `live_loop`s
+together for a final fun example. As usual, don't treat this as a
+finished piece. Start changing things and play around with it and see
+what you can turn it into. See you next time...
+
+
+use_bpm 240
+notes = (scale :e3, :minor_pentatonic).shuffle
+
+live_loop :foo do
+  use_synth :blade
+  with_fx :reverb, reps: 8, room: 1 do
+    tick
+    co = (line 70, 130, steps: 32).tick(:cutoff)
+    play (octs :e3, 3).look, cutoff: co, amp: 2
+    play notes.look, amp: 4
+    sleep 1
+  end
+end
+
+live_loop :bar do
+  tick
+  sample :bd_ada if (spread 1, 4).look
+  use_synth :tb303
+  co = (line 70, 130, steps: 16).look
+  r = (line 0.1, 0.5, steps: 64).mirror.look
+  play notes.look, release: r, cutoff: co
+  sleep 0.5

+3.7 Paquets de samples
+
+# Paquets de samples
+
+**Note: cette section du tutoriel couvre le sujet avancé de
+travailler avec des grands dossiers de vos propres samples. Ce sera le
+cas si vous avez téléchargé ou acheté vos propre paquets de samples et
+souhaitez les utiliser dans Sonic Pi.**
+
+**N'hésitez pas à sauter cette section si vous vous contentez des
+samples fournis dans Sonic Pi.**
+
+Quand on travaille avec de grands dossiers de samples externes il
+peut être ennuyeux de taper le chemin entier chaque fois qu'on veut
+déclencher un sample particulier.
+
+Par exemple, imaginons que vous avez le dossier suivant sur votre
+machine :
+
+```
+/path/to/my/samples/
+```
+
+Quand on regarde dans ce dossier on voit les samples suivants :
+
+* `100_A#_melody1.wav`
+* `100_A#_melody2.wav`
+* `100_A#_melody3.wav`
+* `120_A#_melody4.wav`
+* `120_Bb_guit1.wav`
+* `120_Bb_piano1.wav`
+
+Typiquement pour jouer le sample de piano on peut utiliser le chemin
+complet :
+
+```
+sample "/path/to/my/samples/120_Bb_piano1.wav"
+```
+
+Si on veut jouer le sample de guitare on peut aussi utiliser son
+chemin complet :
+
+```
+sample "/path/to/my/samples/120_Bb_guit.wav"
+```
+
+Cependant ces deux appels de samples nous forcent à *connaître* le nom
+de chacun des samples de notre dossier. Et si on voulait juste écouter
+chaque sample à son tour rapidement ?
+
+## Indexer les paquets de samples
+
+Si on veut jouer le premier sample d'un dossier on peut juste passer
+le nom du dossier à `sample` et l'index `0` comme suit :
+
+```
+sample "/path/to/my/samples/", 0
+```
+
+On peut même construire un raccourci vers notre chemin de dossier en
+utilisant une variable :
+
+```
+samps = "/path/to/my/samples/"
+sample samps, 0
+```
+
+Maintenant, si on veut jouer le deuxième sample de notre dossier, on
+peut juste incrémenter notre index :
+
+```
+samps = "/path/to/my/samples/"
+sample samps, 1
+```
+
+Remarquez qu'on n'a plus besoin de connaître le nom des samples du
+dossier : on doit juste connaître le dossier lui-même (ou avoir un
+raccourci vers lui). Si on demande un index qui est plus grand que le
+nombre de samples, il va juste boucler comme pour les anneaux. Ainsi,
+quel que soit le nombre qu'on utilise on a la garantie de récupérer un
+des samples de ce dossier.
+
+## Filtrer des paquets de samples
+
+D'habitude indexer suffit, mais parfois on a besoin de plus de
+puissance pour trier et organiser nos samples. Heureusement de nombreux
+paquets de samples ajoutent des informations utiles dans les noms de
+fichiers.  Jetons un autre oeil aux noms de fichier des samples de
+notre dossier :
+
+* `100_A#_melody1.wav`
+* `100_A#_melody2.wav`
+* `100_A#_melody3.wav`
+* `120_A#_melody4.wav`
+* `120_Bb_guit1.wav`
+* `120_Bb_piano1.wav`
+
+Remarquez que dans ces noms de fichier nous avons pas mal
+d'informations. On a le BPM du sample (nombre de battements par
+minute) au début. Donc le sample de piano est à 120 BPM et nos trois
+premières mélodies sont à 100 BPM. Nos noms de samples contiennent
+aussi la clef. Donc le sample de guitare est en Bb (si bémol) et les
+mélodies sont en A# (la dièse). Cette information est très utile pour
+mélanger ces samples avec le reste de notre code. Par exemple, on sait
+qu'on ne peut jouer le sample de piano que dans du code qui est à 120
+BPM et dans la clef de Bb.
+
+Il se trouve qu'on peut utiliser cette convention de nommage
+particulière de nos ensembles de samples dans le code pour nous aider
+à ne garder que ceux qu'on veut. Par exemple, si nous travaillons à
+120 BPM, on peut ne garder que les samples qui contiennent la chaîne
+`"120"` avec le code suivant :
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120"
+```
+
+Cela jouera le premier sample qui correspond. Si on veut le deuxième,
+on n'a qu'à utiliser l'index :
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120", 1
+```
+
+On peut même utiliser de multiples filtres en même temps. Par exemple,
+si on veut un sample dont le nom de fichier contient à la fois les
+sous-chaînes "120" et "A#", on peut le trouver facilement avec le code
+suivant :
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120", "A#"
+```
+
+Enfin, on a toujours la possibilité d'ajouter nos options habituelles
+lors de l'appel à `sample`:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120", "Bb", 1, lpf: 70, amp: 2
+```
+
+## Sources
+
+Le système de pré-argument de filtre de samples comprend deux types
+d'information : les sources et les filtres. Les sources sont des
+informations utilisées pour créer la liste des candidats potentiels.
+Une source peut prendre deux formes :
+
+1. "/path/to/samples" : une chaîne représentant un chemin valide vers un dossier
+2. "/path/to/samples/foo.wav" : une chaîne représentant un chemin valide vers un sample
+
+La fonction `sample` va d'abord rassembler toutes les sources et les
+utiliser pour créer une grande liste de candidats. Cette liste est
+construite en ajoutant d'abord tous les chemins valides et puis en
+ajoutant tous les fichiers valides `.flac`, `.aif`, `.aiff`, `.wav`,
+et `.wave` contenus dans les dossiers.
+
+Par exemple, regardez le code suivant :
+
+```
+samps = "/path/to/my/samples/"
+samps2 = "/path/to/my/samples2/"
+path = "/path/to/my/samples3/foo.wav"
+
+sample samps, samps2, path, 0
+```
+
+Ici nous combinons les contenus des samples de deux dossiers en y
+ajoutant un sample en particulier. Si `"/path/to/my/samples/"` contient
+trois samples et `"/path/to/my/samples2/"` en contient douze, on
+aurait seize samples potentiels à indexer et filtrer (3 + 12 + 1).
+
+Par défaut, seuls les fichiers de samples d'un dossier sont rassemblés
+dans la liste de candidats. Parfois vous pourriez avoir un certain
+nombre de dossiers imbriqués dans lesquels vous aimeriez chercher et
+filtrer. Vous pouvez faire une recherche récursive dans tous les
+samples de tous les sous-dossiers d'un dossier en particulier en
+ajoutant `**` à la fin du chemin :
+
+```
+samps = "/path/to/nested/samples/**"
+sample samps, 0
+```
+
+Attention parce que chercher dans un très grand ensemble de dossiers
+peut prendre beaucoup de temps. Cela dit, le contenu des dossiers
+sources est mis en cache, donc le retard n'arrivera que la première
+fois.
+
+
+## Filtres
+
+Une fois qu'on a une liste de candidats on peut utiliser les types de
+filtres suivants pour réduire la sélection :
+
+* `"foo"` : les chaînes vont filtrer sur les occurrences de sous-chaîne dans le nom du fichier (moins le chemin du dossier et l'extension)
+* `/fo[oO]/` : les expressions régulières filtrent sur des motifs du nom du fichier (moins le chemin du dossier et l'extension)
+* `:foo` : les mots-clefs filtrent les candidats si le mot-clef correspond exactement au nom du fichier (moins le chemin du dossier et l'extension)
+* `lambda{ "foo" }` : les procédures sans argument seront appelées automatiquement et leur résultat sera traité comme une source ou un filtre
+* `lambda{|a| ... }` : les procédures avec un argument seront traitées comme un filtre de candidat ou une fonction génératrice. On lui passera la liste des candidats actuels et elle doit retourner une nouvelle liste de candidats (une liste de chemins valides vers des fichiers de samples)
+* `1` : Les nombres sélectionnent le candidat avec cet index (en bouclant comme un anneau si nécessaire)
+
+## Composites
+
+Enfin vous pouvez utiliser des listes partout où on peut placer une
+source ou un filtre. La liste sera automatiquement aplatie et son
+contenu sera traité comme des sources et filtres. Ainsi les appels
+suivants à `sample` sont sémantiquement équivalents :
+
+```
+sample "/path/to/dir", "100", "C#"
+sample ["/path/to/dir", "100", "C#"]
+sample "/path/to/dir", ["100", "C#"]
+sample ["/path/to/dir", ["100", ["C#"]]]
+```
+
+## Résumé
+
+C'était une section avancée pour les gens qui ont besoin de vraie
+puissance pour manipuler et utiliser des paquets de samples. Si la

+8.5 Chaînes d'anneaux
+
+En plus des constructeurs comme `range` et `spread`, une autre façon
+de créer de nouveaux anneaux est de manipuler des anneaux existants.
+
+## Commandes de chaîne
+
+Pour explorer ceci, prenons un anneau simple :
+
+```
+(ring 10, 20, 30, 40, 50)
+```
+
+Et si on voulait son inverse ? Eh bien on utiliserait la commande
+de chaîne `.reverse` pour prendre l'anneau et l'inverser :
+
+```
+(ring 10, 20, 30, 40, 50).reverse  #=> (ring 50, 40, 30, 20, 10)
+```
+
+Et si on voulait les trois premières valeurs de l'anneau ?
+
+```
+(ring 10, 20, 30, 40, 50).take(3)  #=> (ring 10, 20, 30)
+```
+
+Enfin, et si on voulait mélanger l'anneau ?
+
+```
+(ring 10, 20, 30, 40, 50).shuffle  #=> (ring 40, 30, 10, 50, 20)
+```
+
+## Chaînes multiples
+
+C'est déjà une manière puissante de créer de nouveaux anneaux. Ceci
+dit la *vraie* puissance vient quand on enchaîne quelques unes de ces
+commandes à la suite.
+
+Et si on mélangeait l'anneau, on lâchait un élément puis on en prenait
+les trois suivants ?
+
+Regardons ceci par étapes :
+
+1. `(ring 10, 20, 30, 40, 50)` - notre anneau initial
+2. `(ring 10, 20, 30, 40, 50).shuffle` - mélange - `(ring 40, 30, 10, 50, 20)`
+3. `(ring 10, 20, 30, 40, 50).shuffle.drop(1)` - en lâche un - `(ring 30, 10, 50, 20)`
+4. `(ring 10, 20, 30, 40, 50).shuffle.drop(1).take(3)` - en prend trois - `(ring 30, 10, 50)`
+
+Vous voyez comme on peut créer une longue chaîne de ces méthodes juste
+*en les collant à la suite*. On peut les combiner dans l'ordre qu'on
+veut, ce qui crée une manière extrêmement riche et puissante de
+générer de nouveaux anneaux à partir d'anneaux existants.
+
+## Immutabilité
+
+Ces anneaux ont une propriété puissante et importante. Ils sont
+immutables, ce qui veut dire qu'ils ne peuvent pas changer. Cela veut
+dire que les méthodes de chaîne décrites dans cette section *ne
+changent pas les anneaux*, elles *créent plutôt de nouveaux anneaux*.
+Cela veut dire que vous êtes libres de partager des anneaux entre
+fils et de les chaîner dans un fil en sachant que vous n'affecterez
+aucun autre fil qui utilise le même anneau.
+
+## Méthodes de chaîne disponibles
+
+Voici une liste des méthodes de chaîne disponibles :
+
+* `.reverse` - retourne une version inversée de l'anneau
+* `.sort`    - crée une version triée de l'anneau
+* `.shuffle` - crée une version mélangée de l'anneau
+* `.pick(3)` - retourne un anneau avec le résultat de trois appels à `.choose`
+* `.pick`    - similaire à `.pick(3)` mais la taille correspond à la taille de l'anneau initial
+* `.take(5)` - retourne un nouvel anneau contenant uniquement les cinq premiers éléments
+* `.drop(3)` - retourne un nouvel anneau avec tout sauf les trois premiers éléments
+* `.butlast` - retourne un nouvel anneau sans le dernier élément
+* `.drop_last(3)` - retourne un nouvel anneau sans les trois derniers éléments
+* `.take_last(6)`- retourne un nouvel anneau avec les six derniers éléments seulement
+* `.stretch(2)` - répète chaque élément dans l'anneau deux fois
+* `.repeat(3)` - répète l'anneau entier trois fois
+* `.mirror` - ajoute l'anneau à une version inversée de lui-même
+* `.reflect` - comme mirror mais sans dupliquer la valeur du milieu
+
+Evidemment, les méthodes de chaîne qui prennent des nombres peuvent
+prendre d'autres nombres aussi ! N'hésitez donc pas à appeler
+`.drop(5)` au lieu de `.drop(3)` si vous voulez lâcher les cinq
+premiers éléments.

+A.1 Conseils pour Sonic Pi
+
+# Les cinq meilleurs conseils
+
+## 1. Il n'y a pas d'erreur
+
+La plus importante leçon à apprendre avec Sonic Pi c'est qu'il n'y a
+vraiment pas d'erreur. La meilleure façon d'apprendre c'est juste
+d'essayer, essayer, et essayer. Essayez beaucoup de choses
+différentes, ne vous inquiétez pas de savoir si votre code sonne bien
+ou pas et commencez par expérimenter avec le plus de synthés, notes,
+effets et options possibles. Vous découvrirez beaucoup de choses qui
+vous feront rire parce qu'elles ne sonnent pas bien du tout et aussi
+quelques joyaux qui sonnent magnifiquement bien. Débarrassez-vous
+ensuite de ce que vous n'aimez pas et gardez les choses qui vous
+plaisent. Plus vous vous permettrez de faire des erreurs et plus vous
+apprendrez et découvrirez votre son de code personnel.
+
+## 2. Utilisez les effets
+
+Disons que vous maîtrisez déjà les bases de Sonic Pi pour créer des
+sons avec `sample` et `play`. Qu'est-ce qui vient ensuite ? Savez-vous
+que Sonic Pi supporte plus de 27 effets studio pour changer le son de
+votre code ? Les effets sont comme des filtres pour images dans les
+programmes de dessin, mais à la place de rendre l'image floue ou noir
+et blanc, on peut ajouter de la reverb, de la distorsion ou de l'écho
+au son. On peut voir ça comme brancher le câble d'une guitare dans une
+pédale d'effet puis dans un ampli. Heureusement Sonic Pi rend
+l'utilisation d'effets très simple et n'a pas besoin de câble. Tout
+ce dont vous avez besoin c'est de choisir à quelle section de votre
+code ajouter l'effet puis de l'entourer avec le code de l'effet.
+Prenons un exemple. Disons que vous avez le code suivant :
+
+
+    sample :loop_garzul
+     
+    16.times do
+      sample :bd_haus
+      sleep 0.5
+    end
+
+
+Si vous voulez ajouter un effet au sample `:loop_garzul`, il suffit de
+le mettre dans un bloc `with_fx` comme ceci :
+
+
+    with_fx :flanger do
+      sample :loop_garzul
+    end
+     
+    16.times do
+      sample :bd_haus
+      sleep 0.5
+    end
+
+
+Maintenant si voulez ajouter un effet au tambour basse, enveloppez-le
+aussi dans un `with_fx` :
+
+
+    with_fx :flanger do
+      sample :loop_garzul
+    end
+     
+    with_fx :echo do
+      16.times do
+        sample :bd_haus
+        sleep 0.5
+      end
+    end
+
+
+Rappelez-vous, vous pouvez entourer *n'importe quel* code dans
+`with_fx` et tous les sons créés passeront dans cet effet.
+
+
+## 3. Paramétrez vos synthés
+
+Pour découvrir vraiment votre son de code vous voudrez savoir comment
+modifier et contrôler les synthés et effets. Par exemple, vous voudrez
+peut-être changer la durée d'une note, ajouter plus de reverb, ou
+changer la durée entre échos. Heureusement, Sonic Pi vous donne un
+niveau de contrôle incroyable pour faire cela avec des paramètres
+optionnels ou opts pour faire court. Regardons ça rapidement. Copiez
+ce code dans un buffer et exécutez-le :
+
+    sample :guit_em9
+
+
+Oh, un joli son de guitare ! Commençons à jouer un peu avec. Et si on
+changeait sa fréquence ?
+
+    sample :guit_em9, rate: 0.5
+
+
+Hé, qu'est-ce que ce `rate: 0.5` que j'ai ajouté à la fin ? C'est ce
+qu'on appelle une opt. Tous les synthés et samples de Sonic Pi les
+supportent et il y en a beaucoup avec lesquels on peut jouer. Ils
+sont disponibles pour les effets aussi. Essayez ceci :
+
+
+    with_fx :flanger, feedback: 0.6 do
+      sample :guit_em9
+    end
+
+
+Maintenant essayez d'augmenter ce feedback à 1 pour entendre des sons
+fous ! Lisez la documentation pour des détails complets sur les
+nombreuses opts disponibles.
+
+
+## 5. Coder de manière interactive
+
+La meilleure manière d'expérimenter rapidement et d'explorer Sonic Pi
+est de coder de manière interactive. Cela vous permet de partir d'un
+peu de code et de le changer de manière continue pendant qu'il est en
+train de s'exécuter. Par exemple, si vous ne savez pas ce que le
+paramètre cutoff fait à un sample, jouez avec. Essayons ! Copiez ce
+code dans un de vos buffers Sonic Pi :
+
+
+    live_loop :experiment do
+      sample :loop_amen, cutoff: 70
+      sleep 1.75
+    end
+
+
+Maintenant cliquez sur 'Run' et vous entendrez un rhythme de batterie
+un peu étouffé. Maintenant changez la valeur de `cutoff:` en `80` et
+cliquez à nouveau sur 'Run'. Entendez-vous la différence ? Essayez
+`90`, `100`, `110`...
+
+Quand vous aurez pris la main à utiliser des `live_loop`, vous ne
+pourrez plus vous en passer. Quand je donne un concert de live coding
+je m'appuie autant sur `live_loop` qu'un batteur sur ses baguettes.
+Pour plus d'informations à propos du live coding regardez la section
+9 du tutoriel inclus dans Sonic Pi.
+
+## 5. Surfez sur les suites aléatoires
+
+Enfin, une chose que j'adore faire est de tricher en faisant que Sonic
+Pi compose des choses pour moi. Une manière géniale de faire ça est
+d'utiliser l'aléatoire. Cela peut paraître compliqué mais ça ne l'est
+pas du tout. Regardons. Copiez ceci dans un buffer :
+
+
+    live_loop :rand_surfer do
+      use_synth :dsaw
+      notes = (scale :e2, :minor_pentatonic, num_octaves: 2)
+      16.times do
+        play notes.choose, release: 0.1, cutoff: rrand(70, 120)
+        sleep 0.125
+      end
+    end
+
+
+Maintenant, quand vous jouez cela, vous entendrez une suite continue
+de notes aléatoires de la gamme `:e2 :minor_pentatonic` jouée avec le
+synthé `:dsaw`. "Attendez, attendez ! Ce n'est pas une mélodie", vous
+entends-je crier ! Eh bien, voici la première partie du tour de magie.
+Chaque fois que l'on recommence le `live_loop` on peut dire à Sonic Pi
+de fixer la suite aléatoire à un point connu. C'est un peu comme
+voyager dans le temps. Essayons ceci : ajoutez la ligne
+`use_random_seed 1` au `live_loop` :
+
+    live_loop :rand_surfer do
+      use_random_seed 1
+      use_synth :dsaw
+      notes = (scale :e2, :minor_pentatonic, num_octaves: 2)
+      16.times do
+        play notes.choose, release: 0.1, cutoff: rrand(70, 120)
+        sleep 0.125
+      end
+    end
+    
+Maintenant, chaque fois que la `live_loop` boucle, la suite aléatoire
+est réinitialisée. Cela veut dire qu'elle contient exactement les même
+16 notes à chaque fois. Et voilà ! Une mélodie de composée. Et
+maintenant voici la partie excitante. Changez la valeur de `1` en un
+autre nombre. Par exemple `4923`. Ouaou, une autre mélodie ! Donc, en
+changeant juste un nombre (la graine aléatoire), on peut explorer
+autant de combinaisons mélodiques qu'on peut imaginer ! C'est ça la
+magie du code.

+A.2 Live Coding
+
+# Live Coding
+
+Les rayons lasers perçaient à travers les bouffées de fumée et les
+baffles transmettaient des basses profondes dans les corps de la foule.
+L'atmosphère était remplie d'un mélange de synthés et de danse. Il y
+avait pourtant quelque chose d'étrange dans cette boîte de nuit.
+Du texte futuriste était projeté au dessus de la cabine du DJ,
+bougeant, dansant, clignotant. Ce n'étaient pas de belles
+visualisations, c'était juste une projection de Sonic Pi tournant sur
+un Raspberry Pi. La personne dans la cabine de DJ n'était pas en train
+de tourner des disques, elle écrivait, éditait et évaluait du code. En
+direct. C'est ça le Live Coding.
+
+![Sam Aaron Live Coding](../images/tutorial/articles/A.02-live-coding/sam-aaron-live-coding.png)
+
+Cela peut sonner comme une histoire tirée par les cheveux dans une
+boîte de nuit futuriste mais coder de la musique comme cela est une
+tendance qui se développe et qu'on appelle souvent Live Coding
+(programmation interactive) (http://toplap.org). Une des directions
+récentes que cette approche de la musique a prise est l'Algorave
+(http://algorave.com) : des événements où des artistes comme moi
+codent de la musique pour que les gens dansent. Cependant vous n'avez
+pas besoin d'une boîte de nuit pour coder en live : avec Sonic Pi
+version 2.6 et plus vous pouvez le faire dans n'importe quel endroit
+où vous pouvez prendre votre Raspberry Pi et un casque ou des
+haut-parleurs. Quand vous aurez atteint la fin de cet article, vous
+saurez programmez vos rythmes et les modifier en direct. Où vous irez
+ensuite ne sera limité que par votre imagination.
+
+## Boucle interactive
+
+La clef de la programmation interactive est la maîtrise de la
+`live_loop`. En voici une :
+
+    live_loop :beats do
+      sample :bd_haus
+      sleep 0.5
+    end
+
+Il y a quatre ingrédients principaux dans une `live_loop`. La première
+est son nom. Notre `live_loop` s'appelle ici `:beats`. Vous pouvez
+donner le nom que vous voulez à votre `live_loop`. Défoulez-vous.
+Soyez créatifs. J'utilise souvent des noms qui communiquent à
+l'audience qu'est-ce que la musique va faire. Le deuxième ingrédient
+est le mot `do` qui marque où la `live_loop` commence. Le troisième
+est le mot `end` qui marque où la `live_loop` finit, et enfin il y a
+le corps de la `live_loop` qui décrit ce que la boucle va répéter :
+c'est la partie entre `do` et `end`. Dans ce cas on joue en boucle un
+sample de tambour basse et on attend un demi temps. Cela produit un
+beau rythme régulier de basse. Allez, copiez-le dans un buffer vide de
+Sonic Pi et cliquez sur 'Run'. Boum, boum, boum !
+
+## Redéfinir à la volée
+
+OK, qu'est-ce qu'elle a de si spécial, cette `live_loop` ? Jusqu'ici
+on dirait que c'est juste une boucle ! Eh bien, la beauté des
+`live_loop`s c'est qu'on peut les redéfinir à la volée. Cela veut
+dire que pendant qu'elles sont en train de tourner, on peut changer ce
+qu'elles font. C'est le secret de la programmation interactive avec
+Sonic Pi. Essayons :
+
+    live_loop :choral_drone do
+      sample :ambi_choir, rate: 0.4
+      sleep 1
+    end
+
+Maintenant cliquez le bouton 'Run' ou tapez 'alt-r'. Vous entendez
+maintenant de beaux sons de chorale. Ensuite, alors qu'il est encore
+en train de jouer, changer la fréquence de `0.4` en `0.38`. Cliquez à
+nouveau sur 'Run'. Ouaou ! Vous avez entendu le choeur changer de
+note ? Ecrivez à nouveau `0.4` pour revenir comme avant. Puis `0.2`,
+puis `0.19`, puis à nouveau `0.4`. Voyez-vous comment juste changer un
+paramètre à la volée vous donne un réel contrôle sur la musique ?
+Maintenant jouez vous-même avec la fréquence, choisissez vos propres
+valeurs. Essayez des nombres négatifs, de très petits nombres et de
+grands nombres. Amusez-vous !
+
+## Il est important de dormir
+
+Une des leçons les plus importantes avec les `live_loop` c'est
+qu'elles ont besoin de se reposer. Prenons par exemple cette
+`live_loop` :
+
+    live_loop :infinite_impossibilities do
+      sample :ambi_choir
+    end
+
+Si vous essayez d'exécuter ce code, vous verrez immédiatement que
+Sonic Pi se plaint que la `live_loop` n'a pas dormi. C'est un
+mécanisme de sécurité qui se met en place. Prenons un moment pour
+penser à ce que ce code demande à l'ordinateur de faire. C'est cela,
+on demande à l'ordinateur de jouer un nombre infini de samples de
+chorale dans un temps nul. Sans le mécanisme de sécurité le pauvre
+ordinateur essaierait de faire ça et exploserait. Souvenez-vous en
+bien : vos `live_loop`s doivent contenir un appel à `sleep`.
+
+
+## Combiner des sons
+
+La musique est pleine de choses qui arrivent en même temps. La
+batterie en même temps que la basse, en même temps que du chant, en
+même temps que des guitares... En informatique on appelle ça la
+concurrence et Sonic Pi nous donne une manière étonnamment simple de
+jouer des choses en même temps. Il suffit d'utiliser plus qu'une
+`live_loop` !
+
+    live_loop :beats do
+      sample :bd_tek
+      with_fx :echo, phase: 0.125, mix: 0.4 do
+        sample  :drum_cymbal_soft, sustain: 0, release: 0.1
+        sleep 0.5
+      end
+    end
+  
+    live_loop :bass do
+      use_synth :tb303
+      synth :tb303, note: :e1, release: 4, cutoff: 120, cutoff_attack: 1
+      sleep 4
+    end
+
+Ici nous avons deux `live_loop`s, une qui tourne rapidement pour faire
+un rythme et une qui boucle lentement pour faire un son fou de basse.
+
+Une des choses intéressantes quand on utilise plusieurs `live_loop`s
+c'est que chacune gère son propre temps. Cela veut dire qu'il est très
+facile de créer des structures polyrythmiques intéressantes et même de
+jouer avec la phase dans le style de Steve Reich. Par exemple :
+
+    # La phase piano de Steve Reich
+  
+    notes = (ring :E4, :Fs4, :B4, :Cs5, :D5, :Fs4, :E4, :Cs5, :B4, :Fs4, :D5, :Cs5)
+  
+    live_loop :slow do
+      play notes.tick, release: 0.1
+      sleep 0.3
+    end
+  
+    live_loop :faster do
+      play notes.tick, release: 0.1
+      sleep 0.295
+    end
+
+
+## Rassemblons tout
+
+Dans chacun de ces tutoriels, nous finirons avec un exemple qui montre
+un nouveau morceau de musique qui utilise toutes les idées
+introduites. Lisez ce code et essayez d'imaginer ce qu'il fait.
+Ensuite, copiez-le dans un buffer frais de Sonic Pi et cliquez 'Run'
+pour entendre comment il sonne. Enfin changez un des nombres ou
+commentez / décommentez des parties. Voyez si vous pouvez prendre ça
+comme point de départ d'une nouvelle performance, et surtout
+amusez-vous ! A la prochaine...
+
+    with_fx :reverb, room: 1 do

+A.3 Rythmes codés
+
+# Rythmes codés
+
+Une des évolutions techniques les plus excitantes et disruptives dans
+la musique moderne a été l'invention des samplers. C'étaient des
+boîtes qui permettaient d'enregistrer n'importe quels sons dedans et
+de les manipuler et jouer de nombreuses manières intéressantes. Par
+exemple, on pouvait prendre un vieux disque, trouver un solo de
+batterie (ou un break), l'enregistrer dans le sampler et ensuite le
+jouer deux fois moins vite pour créer la fondation de vos derniers
+rythmes. C'est ainsi que la musique hip-hop est née et aujourd'hui il
+est presque impossible de trouver de la musique électronique qui
+n'incorpore pas de samples. Utiliser des samples est une très bonne
+manière d'introduire facilement des éléments nouveaux et intéressants
+dans vos performances de live coding.
+
+Comment pouvez-vous vous procurer un sampler ? Eh bien, vous en avez
+déjà un : c'est votre Raspberry Pi ! L'application de live coding
+Sonic Pi comprend un sampler très puissant. Jouons avec !
+
+## Le break Amen
+
+Un des samples de break de batterie les plus classiques et
+reconnaissables s'appelle le break Amen. Il a été joué pour la
+première fois en 1969 dans la chanson "Amen Brother" des Winstons dans
+un break de batterie. Cependant c'est quand il a été découvert par
+les premiers musiciens de hip-hop dans les années 80 et utilisé dans
+des samplers qu'il a commencé à être très utilisé dans des styles
+aussi variés que le drum and bass, le breakbeat, la techno hardcore et
+le breakcore.
+
+
+Je suis sûr que vous êtes ravis d'entendre qu'il est aussi inclus dans
+Sonic Pi. Choisissez un buffer vide et copiez-y ce code :
+ 
+    sample :loop_amen
+
+Cliquez sur *Run* et boum ! Vous ententez l'un des breaks de batterie
+les plus influents de l'histoire de la musique dance. Ceci dit, ce
+sample n'est pas célèbre pour être joué juste une fois, il est fait
+pour être joué en boucle.
+
+
+## Etirer des rythmes
+
+Jouons le break Amen en boucle en utilisant notre vieille amie la
+`live_loop`, introduite dans le tutoriel du mois dernier :
+
+    live_loop :amen_break do
+      sample :loop_amen
+      sleep 2
+    end
+
+OK, ça boucle, mais il y a une pause ennuyeuse à chaque fois. C'est
+parce qu'on a demandé d'attendre `2` temps et avec le nombre par défaut
+de 60 BPM (battements par minute), le sample `:loop_amen` ne dure que
+`1.753` temps. Nous avons donc un silence de `2 - 1.753 = 0.247`
+temps. Même s'il est court, c'est notable.
+
+Pour corriger ce problème on peut utiliser l'option `beat_stretch`
+pour demander à Sonic Pi d'étirer (ou rétrécir) le sample pour
+correspondre au temps spécifié.
+
+[Breakout box start] Les fonctions `sample` et `synth` de Sonic Pi
+vous donnent beaucoup de contrôle via des paramètres optionnels comme
+`amp:`, `cutoff:` et `release:`. Cela dit le terme `paramètre
+optionnel` est très long à dire donc on les appelle juste *opts* pour
+rester simple.
+[Breakout box end]
+
+    live_loop :amen_break do
+      sample :loop_amen, beat_stretch: 2
+      sleep 2
+    end  
+
+Maintenant on peut danser ! Quoique, peut-être qu'on veut l'accélérer
+ou le ralentir en fonction de l'ambiance.
+
+## Jouer avec le temps
+
+OK, et si on voulait changer de style pour faire du hip hop old school
+ou du breakcore ? Une manière simple de faire ça est de jouer avec le
+temps : ou en d'autres mots jouer avec le tempo. C'est très facile
+avec Sonic Pi : il suffit d'appeler `use_bpm` dans votre boucle
+interactive :
+
+    live_loop :amen_break do
+      use_bpm 30
+      sample :loop_amen, beat_stretch: 2
+      sleep 2
+    end 
+
+Pendant que vous rappez sur ces rythmes lents, remarquez que nous
+avons toujours un repos de 2 et que notre BPM vaut 30, mais tout est
+bien synchronisé. L'option `beat_stretch` marche avec le BPM courant
+pour s'assurer que tout fonctionne bien.
+
+Maintenant voici la partie amusante. Alors que la boucle est en train
+de tourner, changez le `30` dans la ligne `use_bpm 30` en `50`. Oh,
+tout est devenu plus rapide, mais toujours *synchro* ! Essayez d'aller
+plus vite : jusque 80, jusque 120, ou même, soyons fous, 200 !
+
+
+## Filtrer
+
+Maintenant qu'on peut jouer des samples en boucle de manière
+interactive, regardons les options les plus amusantes proposées par le
+synthé `sample`. La première est le `cutoff:` qui contrôle le filtre
+de coupure du sampler. Par défaut il est désactivé mais on peut
+facilement l'activer :
+
+
+    live_loop :amen_break do
+      use_bpm 50
+      sample :loop_amen, beat_stretch: 2, cutoff: 70
+      sleep 2
+    end  
+
+
+Allez-y, changez la valeur de l'option `cutoff:`. Par exemple
+montez-la à 100, cliquez sur *Run* et attendez la prochaine boucle
+pour entendre la différence dans le son. Remarquez que des valeurs
+basses comme 50 sonnent plus doux et bas et que des hautes valeurs
+comme 100 ou 120 sonnent plus plein et râpeux. C'est parce que
+l'option `cutoff:` va couper les parties haute-fréquence du son tout
+comme une tondeuse coupe le haut de la pelouse. L'option `cutoff:`
+est comme le réglage de la longueur : cela détermine combien il reste
+d'herbe.
+
+
+## Couper
+
+Un autre super outil avec lequel on peut jouer est l'effet slicer.
+Il va couper le son en tranches. Entourez la ligne de `sample` avec le
+code de l'effet ainsi :
+
+    live_loop :amen_break do
+      use_bpm 50
+      with_fx :slicer, phase: 0.25, wave: 0, mix: 1 do
+        sample :loop_amen, beat_stretch: 2, cutoff: 100
+      end
+      sleep 2
+    end
+
+Remarquez comme le son bondit un peu plus de haut en bas. (Vous pouvez
+entendre le son original sans l'effet en changeant l'option `mix:` en
+`0`.) Maintenant essayez de modifier la valeur de l'option `phase:`.
+C'est la fréquence (en battements) de l'effet de coupe. Une plus
+petite valeur comme `0.5` va couper plus rapidement et une plus grande
+valeur comme `0.5` va couper plus lentement. Remarquez que si on
+divise ou multiplie successivement par deux l'option `phase:` cela
+sonne généralement bien. Enfin, choisissez une valeur pour l'option
+`wave:` entre 0, 1 et 2 et écoutez comment le son change. Ce sont
+différentes formes d'onde. 0 est une onde scie (elle commence fort et
+finit en fondu), 1 est une onde carrée (commence et finit fort) et 2
+est une onde en triangle (commence en fondu, finit en fondu).
+
+## Rassemblons tout
+
+Enfin, revenons dans le temps et revisitons la jeune scène de drum and
+bass de Bristol avec l'exemple de ce mois. Ne vous inquiétez pas trop
+de tout ce que cela signifie, tapez le, cliquez sur Run, puis
+commencez à coder interactivement en changement les valeurs des
+options et voyez où cela vous amène. Partagez ce que vous créez ! A la
+prochaine...
+
+    use_bpm 100
+  
+    live_loop :amen_break do
+      p = [0.125, 0.25, 0.5].choose
+      with_fx :slicer, phase: p, wave: 0, mix: rrand(0.7, 1) do
+        r = [1, 1, 1, -1].choose
+        sample :loop_amen, beat_stretch: 2, rate: r, amp: 2
+      end
+      sleep 2
+    end
+  
+    live_loop :bass_drum do
+      sample :bd_haus, cutoff: 70, amp: 1.5
+      sleep 0.5
+    end
+  
+    live_loop :landing do
+      bass_line = (knit :e1, 3, [:c1, :c2].choose, 1)
+      with_fx :slicer, phase: [0.25, 0.5].choose, invert_wave: 1, wave: 0 do
+        s = synth :square, note: bass_line.tick, sustain: 4, cutoff: 60
+        control s, cutoff_slide: 4, cutoff: 120
+      end
+      sleep 4
+    end

+A.4 Riffs de synthés
+
+# Riffs de synthés
+
+Que ce soit la dérive hantée d'oscillateurs grondants ou le coup de
+poing désaccordé des ondes scies perçant à travers le mix, le synthé
+principal joue un rôle essentiel dans chaque piste électronique. Dans
+l'édition du mois dernier de cette série de tutoriels nous avons
+couvert comment coder nos rythmes. Dans ce tutoriel nous verrons
+comment coder les trois composants principaux d'un riff de synthé : le
+timbre, la mélodie et le rythme.
+
+OK, allumez votre Raspberry Pi, ouvrez Sonic Pi (version 2.6 ou plus)
+et faisons du bruit !
+
+
+## Les possibilités du timbre
+
+Une partie essentielle de n'importe quel riff de synthé est de jouer
+avec le timbre des sons. On peut contrôler le timbre dans Sonic Pi de
+deux manières : en choisissant différents synthés pour un changement
+dramatique et en définissant les diverses options des synthés pour des
+modifications plus subtiles. On peut aussi utiliser des effets, mais
+ce sera pour un autre tutoriel...
+
+Créons une boucle interactive simple où l'on modifiera en continu le
+synthé courant :
+
+    live_loop :timbre do
+      use_synth (ring :tb303, :blade, :prophet, :saw, :beep, :tri).tick
+      play :e2, attack: 0, release: 0.5, cutoff: 100
+      sleep 0.5
+    end
+
+Regardez ce code. On parcourt (avec `tick`) juste un anneau de noms de
+synthés (on boucle sur chacun d'eux à leur tour puis on répéte la
+liste encore et encore). On passe ce nom de synthé à la fonction (fn)
+`use_synth`, ce qui changera le synthé courant de la `live_loop`. On
+joue aussi la note `:e2` (E (ou Mi) à la deuxième octave), avec un
+temps de relâche de 0.5 battement (une demi seconde au BPM par défaut
+de 60) et avec l'option `:cutoff` fixée à 100.
+
+Vous entendez que les différents synthés ont des sons très différents
+même s'ils jouent tous la même note. Maintenant expérimentez et jouez.
+Changez le temps de relâche en lui donnant des valeurs plus grandes et
+plus petites. Par exemple, changez les options `attack:` et `release:`
+pour voir comme des temps différents de fondu d'entrée et de sortie
+ont un grand effet sur le son. Enfin changez l'option `cutoff:` pour
+voir comment différentes valeurs de coupure ont une influence massive
+sur le timbre (des valeurs entre 60 et 130 sont bonnes). Voyez combien
+de sons vous pouvez créer juste en changeant quelques valeurs. Une
+fois que vous maîtrisez cela, allez dans l'onglet Synthés dans le
+système d'aide pour voir la liste entière des synthés et des options
+que chacun d'eux supporte pour voir l'étendue du pouvoir que vous avez
+au bouts de vos doigts de codeur.
+
+## Timbre
+
+Le timbre est juste un mot savant pour décrire comment sonne un son.
+Si vous jouez la même note avec différents instruments comme un
+violon, une guitare, ou un piano, la fréquence (si elle sonne haut ou
+bas) sera la même, mais la qualité du son sera différente. La qualité
+du son, ce qui fait qu'on peut différencier un piano et une guitare,
+c'est le timbre.
+
+## Composition mélodique
+
+Un autre aspect important de notre synthé principal est le choix de
+notes que l'on veut jouer. Si vous avez déjà une bonne idée, alors
+vous pouvez juste créer un anneau avec vos notes et les parcourir :
+
+    live_loop :riff do
+      use_synth :prophet
+      riff = (ring :e3, :e3, :r, :g3, :r, :r, :r, :a3)
+      play riff.tick, release: 0.5, cutoff: 80
+      sleep 0.25
+    end
+
+Ici nous avons défini une mélodie avec un anneau qui inclut des notes
+comme `:e3` et des silences représentés par `:r`. On utilise ensuite
+`.tick` pour jouer chaque note à son tour, ce qui nous donne un riff
+qui se répète.
+
+## Mélodie automatique
+
+Ce n'est pas toujours facile d'inventer un riff sympa. C'est souvent
+plus simple de demander à Sonic Pi une sélection de riffs aléatoires
+et de choisir celui que l'on préfère. Pour faire cela on doit combiner
+trois choses : des anneaux, de l'aléatoire et des graines aléatoires.
+Regardons un exemple :
+
+    live_loop :random_riff do
+      use_synth :dsaw
+      use_random_seed 3
+      notes = (scale :e3, :minor_pentatonic).shuffle
+      play notes.tick, release: 0.25, cutoff: 80
+      sleep 0.25
+    end
+
+Plusieurs choses se passent : regardons les une par une. On commence
+par spécifier la graine aléatoire 3. Qu'est-ce que cela signifie ? Eh
+bien, c'est utile parce que quand on définit la graine, on sait
+prédire quelle sera la prochaine valeur aléatoire : ce sera la même
+que la dernière fois qu'on a choisi la graine 3 ! Une autre chose
+utile à savoir est que mélanger un anneau de notes fonctionne de la
+même façon. Dans l'exemple ci-dessus c'est comme si on demandait le
+'troisième mélange' dans la liste standard de mélanges : il sera le
+même chaque fois comme on définit toujours la graine aléatoire à la
+même valeur avant le mélange. Enfin on parcourt juste nos notes
+mélangées pour jouer le riff.
+
+Maintenant, c'est ici qu'on commence à s'amuser. Si on change la
+valeur de la graine aléatoire, par exemple en 3000, on a un mélange
+entièrement différent des notes. Ainsi il est très facile d'explorer
+de nouvelles mélodies. Il suffit de choisir la liste de notes que l'on
+veut mélanger (les gammes sont un très bon endroit pour commencer) et
+ensuite de choisir la graine avec laquelle on veut les mélanger. Si on
+n'aime pas la mélodie, on peut juste changer une de ces deux choses et
+essayer à nouveau. Répétez jusqu'à ce que vous aimiez ce que vous
+entendez !
+
+
+## Pseudo aléatoire
+
+L'aléatoire de Sonic Pi n'est pas vraiment aléatoire, on appelle ça du
+pseudo aléatoire. Imaginez que vous jetez un dé 100 fois et que vous
+écrivez le résultat de chaque jet sur une feuille de papier. Sonic Pi
+a l'équivalent de cette liste de résultats qu'il utilise quand on
+demande une valeur aléatoire. Au lieu de jeter un vrai dé, il prend
+juste la valeur suivante dans la liste. Définir la graine aléatoire
+revient à sauter à un endroit particulier de cette liste.
+
+## Trouver votre rythme
+
+Un autre aspect important de notre riff est le rythme : quand jouer
+une note et quand ne pas le faire. Comme on a vu, on peut utiliser
+`:r` dans nos anneaux pour insérer des silences. Une autre manière
+puissante consiste à utiliser des 'spreads' que l'on couvrira dans un
+futur tutoriel. Aujourd'hui nous allons utiliser l'aléatoire pour nous
+aider à trouver notre rythme. Au lieu de jouer toutes les notes on
+peut utiliser une condition pour jouer une note avec une probabilité
+donnée. Voyons cela :
+
+    live_loop :random_riff do
+      use_synth :dsaw
+      use_random_seed 30
+      notes = (scale :e3, :minor_pentatonic).shuffle
+      16.times do
+        play notes.tick, release: 0.2, cutoff: 90 if one_in(2)
+        sleep 0.125
+      end
+    end
+
+Une fonction très utile à connaître est `one_in` qui nous donne une
+valeur `true` ou `false` (vrai ou faux) avec la probabilité spécifiée.
+Ici nous utilisons une valeur de 2 donc en moyenne un appel sur deux à
+`one_in` retournera `true`. En d'autres termes, elle retournera `true`
+50% du temps. Si on choisit des valeurs plus grandes elle retournera
+`false` plus souvent ce qui mettra plus d'espace dans notre riff.
+
+Remarquez qu'on a introduit un peu d'itération ici avec `16.times`.
+C'est parce qu'on ne veut redéfinir notre valeur de graine aléatoire
+que toutes les 16 notes pour que notre rythme se répète toutes les 16
+fois. Cela n'affecte pas le mélange comme il est toujours fait juste
+après avoir défini la graine. On peut utiliser la longueur d'itération
+pour modifier la longueur de notre riff. Essayez de changer le 16 en 8
+ou même en 4 ou 3 et voyez comment cela affecte le rythme du riff.
+
+## Rassemblons tout
+
+OK, combinons tout ce que nous avons appris dans un dernier exemple.
+A la prochaine !
+
+    live_loop :random_riff do
+      #  uncomment to bring in:
+      #  synth :blade, note: :e4, release: 4, cutoff: 100, amp: 1.5
+      use_synth :dsaw
+      use_random_seed 43
+      notes = (scale :e3, :minor_pentatonic, num_octaves: 2).shuffle.take(8)
+      8.times do
+        play notes.tick, release: rand(0.5), cutoff: rrand(60, 130) if one_in(2)
+        sleep 0.125
+      end
+    end

+        sleep 0.125
+      end
+    end
+

+A.5 Basse acide
+
+# Basse acide
+
+Il est impossible de regarder l'histoire de la musique de danse
+électronique sans voir l'énorme impact du petit synthétiseur Roland
+TB-303. C'est la sauce secrète derrière le son original de basse
+acide. On entend ces riffs de basse classiques crissants et
+pataugeants depuis la jeune scène de house de Chicago jusqu'à des
+artistes plus récents comme Plastikman, Squarepusher et Aphex Twin.
+
+Il est intéressant de savoir que Roland n'avait pas l'intention que le
+TB-303 soit utilisé dans de la musique pour danser. Il a été créé à
+l'origine comme une aide de travail pour les guitaristes. Ils ont
+imaginé que les gens les programmeraient pour jouer des lignes de
+basse d'accompagnement. Malheureusement il y avait un certain nombre
+de problèmes : ils étaient un peu compliqués à programmer, ne
+sonnaient pas particulièrement bien comme remplacement de guitare
+basse et ils étaient assez chers. Décidant d'arrêter les frais, Roland
+a cessé d'en fabriquer après en avoir vendu 10'000 unités et après un
+certain nombres d'années à rester sur les étagères des guitaristes,
+ils se retrouvés dans les vitrines des magasins d'occasion. C'est
+pauvres TB-303 rejetés attendaient d'être découverts par une nouvelle
+génération d'expérimentateurs qui ont commencé à les utiliser dans des
+manières que Roland n'avait pas imaginées pour créer des sons fous.
+La house acide était née.
+
+
+Même si se procurer un TB-303 original n'est pas si facile vous serez
+heureux d'apprendre que vous pouvez transformer votre Raspberry Pi en
+TB-303 en utilisant la puissance de Sonic Pi. Lancez Sonic Pi, copiez
+ce code dans un buffer vide et cliquez sur 'Run' :
+
+    use_synth :tb303
+    play :e1
+    
+Instant acid bass! Let's play around...
+
+# Presse cette basse
+
+Commençons par construire un arpège interactif pour rendre les choses
+amusantes. Dans le dernier tutoriel nous avons vu comment des mélodies
+peuvent être juste un anneau de notes qu'on joue les unes après les
+autres, en répétant quand on arrive à la fin. Créons une boucle
+interactive qui fait cela :
+
+    use_synth :tb303
+    live_loop :squelch do
+      n = (ring :e1, :e2, :e3).tick
+      play n, release: 0.125, cutoff: 100, res: 0.8, wave: 0
+      sleep 0.125
+    end
+    
+Regardons chaque ligne.
+
+1. A la première ligne choisit `tb303` comme synthé par défaut avec la
+  fonction `use_synth`.
+
+2. A la deuxième ligne on crée une boucle interactive du nom de
+   `:squelch` qui va juste boucler encore et encore.
+
+3. A la troisième ligne on crée notre mélodie : un anneau de notes (E
+   ou Mi aux octaves 1, 2 et 3) et on le parcourt simplement avec
+   `.tick`. On définit `n` pour représenter la note courante de la
+   mélodie. Le signe égal veut juste dire qu'on affecte la valeur à
+   droite au nom à gauche. Cette valeur sera différente à chaque
+   boucle. La première fois `n` aura la valeur `:e1`. La deuxième fois
+   ce sera `:e2`, puis `:e3`, puis de nouveau `:e1`, en bouclant à
+   l'infini.
+   
+4. A la ligne quatre on joue notre synthé `:tb303`. On lui passe
+   quelques options intéressantes : `release:`, `cutoff:`, `res:` et
+   `wave:` que l'on décrira plus bas.
+
+5. La ligne cinq est notre `sleep` : on demande à la boucle
+   interactive de boucler toutes les `0.125`secondes ou 8 fois par
+   seconde au BPM par défaut de 60
+   
+6. La ligne six est la fin de la boucle interactive. Le mot `end`
+   indique juste à Sonic Pi où se termine la boucle interactive.
+
+
+Alors que vous êtes encore en train de vous familiariser avec ce qui
+se passe, tapez le code ci-dessous et cliquez sur le bouton 'Run'.
+Vous devriez entendre le `:tb303` entrer en action. C'est ici le coeur
+de l'action : commençons à programmer de manière interactive.
+
+Pendant que la boucle tourne, changez l'option `cutoff:` en `110`.
+Puis cliquez à nouveau sur le bouton 'Run'. Vous devriez entendre le
+son devenir un peu plus dur et sec. Montez à `120` et cliquez sur
+'Run'. Puis `130`. Ecoutez comme les valeurs hautes de coupure rendent
+le son plus perçant et intense. Enfin, descendez à `80` quand vous
+sentirez que vous voulez un peu de repos. Puis répétez ça autant que
+vous voulez. Pas d'inquiétude, je serai toujours là...
+
+Une autre option qui vaut le coup d'être utilisée est `res:`. Elle
+contrôle le niveau de résonance du filtre. Une haute résonance est
+caractéristique des sons de basse acide. Nous avons pour le moment une
+`res:` de `0.8`. Essayez de la monter à `0.85`, puis `0.9`, et enfin
+`0.95`. Un cutoff de `110` ou plus peut permettre d'entendre plus
+facilement les différences. Enfin défoulez-vous et montez jusque
+`0.999` pour avoir des sons déments. Avec une `res` aussi haute vous
+entendez le filtre de coupure résonner tant qu'il commence à faire ses
+propres sons.
+
+Enfin pour avoir un grand impact sur le timbre essayez de mettre
+l'option `wave:` à `1`. C'est le choix de l'oscillateur source. La
+valeur par défaut est `0` qui est une onde en dents de scie.
+
+Bien sûr, essayez différentes mélodies en changeant les notes dans
+l'anneau ou même en choisissant des notes de gammes ou d'accords.
+Amusez-vous bien avec votre premier synthé de basse acide.
+
+# Déconstruisons le TB-303
+
+Le design du TB-303 original était en fait assez simple. Comme vous
+pouvez le voir sur le diagramme suivant il n'y a que quatre parties
+principales.
+
+![TB-303 Design](../images/tutorial/articles/A.05-acid-bass/tb303-design.png)
+
+En premier on a l'onde oscillatoire : les ingrédients de base du son.
+Dans ce cas nous avons une onde carrée. Ensuite on a l'enveloppe
+d'amplitude de l'oscillateur qui contrôle l'amplitude de l'onde carrée
+au cours du temps. On peut y accéder dans Sonic Pi avec les options 
+`attack:`, `decay:`, `sustain:` et `release:` ainsi que leur niveau
+correspondant. Pour plus d'informations lisez la Section 2.4 'Durée
+avec enveloppes' dans le tutoriel inclus dans Sonic Pi. On passe
+ensuite notre onde carrée enveloppée dans un filtre passe bas
+résonant. Cela coupe les hautes fréquences et a un bel effet de
+résonance. Et c'est ici que ça devient amusant. La valeur de coupure
+de ce filtre est aussi contrôlée par sa propre enveloppe ! Cela veut
+dire que nous avons un contrôle incroyable sur le timbre du son en
+jouant avec ces deux enveloppes. Jetons-y un oeil :
+
+  
+    use_synth :tb303
+    with_fx :reverb, room: 1 do
+      live_loop :space_scanner do
+        play :e1, cutoff: 100, release: 7, attack: 1, cutoff_attack: 4, cutoff_release: 4
+        sleep 8
+      end
+    end
+    
+Pour chaque option standard d'enveloppe, il y a une option `cutoff_`
+équivalente dans le synthé `:tb303`. Donc, pour changer le temps
+d'attaque de la coupure on peut utiliser l'option `:cutoff_attack`.
+Copiez le code ci-dessus dans un buffer vide et cliquez sur 'Run'.
+Vous entendrez un son fou entrer et sortir. Maintenant essayez de
+jouer avec. Essayez de changer la durée de `cutoff_attack:` en `1`
+puis en `0.5`. Puis essayez `8`.
+
+Remarquez que j'ai passé tout cela à travers un effet `:reverb` pour
+plus d'atmosphère : essayez d'autres effets pour voir ce qui marche !
+
+## Rassemblons tout
+
+Enfin voici un morceau que j'ai composé en utilisant les idées de ce
+tutoriel. Copiez le dans un buffer vide, écoutez un peu, puis
+commencez à programmer interactivement vos changements. Voyez quels
+sons fous vous pouvez faire avec ! A la prochaine...
+
+    use_synth :tb303
+    use_debug false
+     
+    with_fx :reverb, room: 0.8 do
+      live_loop :space_scanner do
+        with_fx :slicer, phase: 0.25, amp: 1.5 do
+          co = (line 70, 130, steps: 8).tick
+          play :e1, cutoff: co, release: 7, attack: 1, cutoff_attack: 4, cutoff_release: 4
+          sleep 8
+        end
+      end
+     
+      live_loop :squelch do
+        use_random_seed 3000
+        16.times do
+          n = (ring :e1, :e2, :e3).tick
+          play n, release: 0.125, cutoff: rrand(70, 130), res: 0.9, wave: 1, amp: 0.8
+          sleep 0.125
+        end
+      end
+    end

+A.6 Minecraft musical
+
+# Minecraft musical
+
+
+
+Bonjour et bienvenue à nouveau ! Dans les tutoriels précédents nous
+nous somes concentrés exclusivement sur les possibilités mnusicales de
+Sonic Pi, en transformant votre Raspberry Pi en instrument de musique
+prêt à l'emploi. Jusqu'ici nous avons appris comment :
+
+* Programmer de manière interactive, en changeant les sons à la volée,
+* Coder des rythmes imposants,
+* Générer des mélodies de synthé puissantes
+* recréer le fameux son TB-303 de basse acide
+
+Il y a tellement plus à vous montrer, et nous l'explorerons dans de
+futures éditions. Cependant, ce mois-ci, nous allons regarder une
+chose que Sonic Pi sait faire et que vous n'avez probablement pas
+remarquée : contrôler Minecraft.
+
+
+# Bonjour, monde de Minecraft
+
+OK, commençons. Démarrez votre Raspberry Pi, lancez Minecraft Pi et
+créez un nouveau monde. Maintenant démarrez Sonic Pi et déplacez vos
+fenêtres de manière à pouvoir voir Sonic Pi et Minecraft Pi en même
+temps.
+
+Dans un buffer disponible tapez ce qui suit :
+
+    mc_message "Hello Minecraft from Sonic Pi!"
+    
+Maintenant cliquez sur 'Run'. Boum ! Votre message est apparu dans
+Minecraft ! C'était facile, non ? Maintenant arrêtez un moment de lire
+ceci et jouez un peu avec vos propres messages. Amusez-vous !
+
+![Screen 0](../images/tutorial/articles/A.06-minecraft/Musical-Minecraft-0-small.png)
+
+# Téléportation sonique
+
+Explorons un peu. L'option standard est de saisir la souris et le
+clavier et de commencer à se promener. Ca marche, mais c'est assez
+lent et ennuyeux. Ce serait beaucoup mieux si on avait une sorte de
+machine de téléportation. Eh bien, grâce à Sonic Pi, on en a une.
+Essayez ceci :
+
+    mc_teleport 80, 40, 100
+    
+Oh ! On est monté bien haut. Si vous n'étiez pas en mode volant vous
+avez du retomber jusqu'au sol. Si vous double-tapez Espace pour entrer
+en mode volant et vous téléportez à nouveau, vous resterez en l'air
+à l'endroit où vous vous êtes déplacés.
+
+Maintenant, qu'est-ce que ces nombres signifient ? Nous avons trois
+nombres qui décrivent les coordonnées de l'endroit du monde où vous
+voulez vous déplacer. On donne à chacun de ces nombres un nom : x, y
+et z.
+
+* x - à quelle distance vers la gauche ou la droite (80 dans notre exemple)
+* y - à quelle hauteur on veut être (40 dans notre exemple)
+* z - à quelle distance vers l'avant ou l'arrière (100 dans notre exemple)
+
+En choisissant différentes valeurs pour x, y, et z, on peut se
+téléporter *n'importe où* dans notre monde. Essayez ! Choisissez
+différents nombres et regardez où vous vous retrouvez. Si l'écran
+devient noir c'est que vous vous êtes téléportés sous terre ou dans
+une montagne. Choisissez juste une valeur de y plus grande pour vous
+retrouver au-dessus de la terre. Continuez à explorer jusqu'à ce que
+vous trouviez un endroit qui vous plaise...
+
+En utilisant les idées vues jusqu'ici, construisons un téléporteur
+sonique qui fera un son amusant de téléportation quand il nous fera
+voyager à travers le monde de Minecraft :
+
+    mc_message "Preparing to teleport...."
+    sample :ambi_lunar_land, rate: -1
+    sleep 1
+    mc_message "3"
+    sleep 1
+    mc_message "2"
+    sleep 1
+    mc_message "1"
+    sleep 1
+    mc_teleport 90, 20, 10
+    mc_message "Whoooosh!"
+    
+![Screen 1](../images/tutorial/articles/A.06-minecraft/Musical-Minecraft-1-small.png)
+
+# Blocs magiques
+
+Maintenant que vous avez trouvé un endroit sympathique, commençons à
+construire. Vous pourriez faire comme vous en avez l'habitude et
+commencer à cliquer furieusement la souris pour placer des blocs sous
+le curseur. Ou vous pourriez utiliser la magie de Sonic Pi. Essayez
+ceci :
+
+
+    x, y, z = mc_location
+    mc_set_block :melon, x, y + 5, z
+
+Maintenant regardez vers le haut ! Il y a un melon dans le ciel !
+Prenez un moment pour regarder le code. Qu'est-ce qu'on a fait ? Sur
+la première ligne on a attrapé l'emplacement actuel de Steve dans les
+variables x, y et z. Elles correspondent aux coordonnées décrites
+ci-dessus. Nous utilisons ces coordonnées dans la fonction
+`mc_set_block` qui va placer le bloc de votre choix aux coordonnées
+spécifiées. Pour placer quelque chose plus haut dans le ciel on doit
+juste augmenter la valeur de y, c'est pour ça qu'on lui ajoute 5.
+Faisons un chemin de melons :
+
+    live_loop :melon_trail do
+      x, y, z = mc_location
+      mc_set_block :melon, x, y-1, z
+      sleep 0.125
+    end
+
+Maintenant sautez dans Minecraft, assurez-vous d'être en mode volant
+(tapez deux fois sur Espace sinon) et volez autour du monde. Regardez
+derrière vous pour voir un beau chemin de blocs de melon ! Voyez quels
+dessins tordus vous pouvez faire dans le ciel.
+
+# Programmer Minecraft de manière interactive
+
+Ceux d'entre vous qui ont suivi ce tutoriel pendant les derniers mois
+doivent être bien étonnés. Le chemin de melons est assez cool, mais la
+partie la plus excitante de l'exemple précédent est qu'on peut
+utiliser la `live_loop` avec Minecraft ! Pour ceux qui ne savent pas,
+la `live_loop` est la faculté magique et spéciale de Sonic Pi qu'aucun
+autre langage de programmation ne possède. Elle vous permet d'exécuter
+des boucles multiples en même temps et vous permet de les modifier
+pendant qu'elles tournent. Elles sont incroyablement puissantes et
+amusantes. J'utilise les `live_loop`s pour jouer de la musique dans
+des boîtes de nuit avec Sonic Pi : les DJs utilisent des disques et
+moi j'utilise des `live_loop`s :-) Cependant aujourd'hui nous allons
+programmer de manière interactive de la musique et Minecraft.
+
+
+
+Commençons. Exécutez le code ci-dessus et commencez à faire votre
+chemin de melons de nouveau. Maintenant, sans arrêter le code, changez
+simplement `:melon` en `:brick` et cliquez sur `Run`. Eh voilà, vous
+construisez maintenant un chemin de briques. C'était simple, non ?
+Un peu de musique pour accompagner ça ? Facile. Essayez ceci :
+
+    live_loop :bass_trail do
+      tick
+      x, y, z = mc_location
+      b = (ring :melon, :brick, :glass).look
+      mc_set_block b, x, y -1, z
+      note = (ring :e1, :e2, :e3).look
+      use_synth :tb303
+      play note, release: 0.1, cutoff: 70
+      sleep 0.125
+    end
+    
+Maintenant pendant que ça joue commencez à modifier le code. Changez
+les types de bloc : essayez `:water`, `:grass` ou votre type de bloc
+préféré. Aussi, essayez de changer la valeur de coupure de `70` à `80`
+puis jusque `100`. N'est-ce pas amusant ?
+
+## Rassemblons tout
+
+![Screen 2](../images/tutorial/articles/A.06-minecraft/Musical-Minecraft-2-small.png)
+
+Rassemblons tout ce que nous avons vu jusqu'ici avec un peu de magie
+en plus. Combinons notre faculté de téléportation avec placement de
+blocs et la musique pour faire une vidéo de musique Minecraft. Ne vous
+inquiétez pas si vous ne comprenez pas tout, tapez juste le code et
+jouez ensuite à modifier quelques-unes des valeurs pendant qu'il
+s'exécute. Amusez-vous bien et à la prochaine...
+    
+
+    live_loop :note_blocks do
+      mc_message "This is Sonic Minecraft"
+      with_fx :reverb do
+        with_fx :echo, phase: 0.125, reps: 32 do
+          tick
+          x = (range 30, 90, step: 0.1).look
+          y = 20
+          z = -10
+          mc_teleport x, y, z
+          ns = (scale :e3, :minor_pentatonic)
+          n = ns.shuffle.choose
+          bs = (knit :glass, 3, :sand, 1)

+A.7 Battements de Bizet
+
+# Battements de Bizet
+
+Après notre briève excursion dans le monde fantastique de la
+programmation Minecraft avec Sonic Pi le mois dernier, penchons nous
+sur la musique à nouveau. Aujourd'hui nous allons amener un morceau
+classique de danse d'opéra droit dans le 21e siècle en utilisant
+la puissance fantastique du code.
+
+# Scandaleux et perturbateur
+
+Sautons dans une machine à remonter le temps jusqu'en 1875. Un
+compositeur nommé Bizet avait juste terminé son dernier opéra :
+Carmen. Malheureusement comme beaucoup de nouveaux morceaux excitants
+et perturbateurs les gens ne l'aimaient pas du tout au début parce
+qu'il était trop scandaleux et différent. Malheureusement Bizet est
+mort dix ans avant que l'opéra ne connaisse un grand succès
+international et ne devienne un des opéras les plus connus et les plus
+fréquemment interprétés de tous les temps. Par sympathie pour cette
+tragédie nous allons prendre un des thèmes principaux de Carmen et
+nous allons le convertir dans un format moderne de musique qui est
+aussi trop scandaleux et différent pour la plupart des gens de notre
+époque : la musique codée interactive !
+
+# La Habanera décryptée
+
+Essayez de programmer un opéra entier de manière interactive serait un
+peu ambitieux pour ce tutoriel, concentrons nous sur une des ses plus
+célèbres parties : la ligne de basse de la Habanera :
+
+![Habanera Riff](../images/tutorial/articles/A.07-bizet/habanera.png)
+
+Cela peut vous sembler complètement illisible si vous n'avez pas
+étudié la notation musicale. Cependant, en tant que programmeurs nous
+voyons la notation musicale comme juste une autre forme de code, elle
+représente juste des instructions pour un musicien au lieu d'un
+ordinateur.
+
+# Notes
+
+Les notes sont arrangées de gauche à droite comme les mots dans ce
+magasine mais elles ont aussi différentes hauteurs. *La hauteur sur la
+partition représente la hauteur d'une note.* Plus une note est haut
+sur la partition, plus sa hauteur est grande.
+
+Dans Sonic Pi nous savons déjà comment changer la hauteur d'une note :
+on peut utiliser des grands ou petits nombres comme `play 75` et
+`play 80` ou on peut utiliser les noms des notes : `play :E` et
+`play :F`. Heureusement chacune des positions verticales sur la
+partition représente un nom de note en particulier. Jetez un oeil à
+cette table de correspondance bien pratique :
+
+![Notes](../images/tutorial/articles/A.07-bizet/notes.png)
+
+# Silences
+
+Les partitions sont une sorte de code extrêmement riche et expressif
+capable de communiquer de nombreuses choses. Cela ne devrait donc pas
+nous surprendre que les partitions peuvent non seulement nous dire
+quelles notes jouer mais aussi quand *ne pas* jouer de note. En
+programmation c'est à peu près l'équivalent de l'idée de `nil` ou
+`null` : l'absence de valeur. En d'autres mots ne pas jouer une note
+c'est comme une absence de note.
+
+Si vous regardez de près la partition vous verrez que c'est en fait
+une combinaison de ronds noirs avec des barres qui représentent les
+notes à jouer et des choses ondulées qui représentent les silences.
+Heureusement, Sonic Pi a une notation très pratique pour un silence :
+`:r`, donc si on exécute `play :r` il jouera en fait un silence ! On
+pourrait aussi écrire `play :rest`, `play nil` ou `play false` qui
+sont autant de manières équivalentes de représenter un silence.
+
+# Rythme
+
+Enfin il y a une dernière chose à apprendre à décoder dans la
+notation : la notion du temps. Dans la notation originale vous verrez
+que les notes sont liées par des traits épais. La deuxième note a
+deux de ces traits ce qui veut dire qu'elle dure un 16e de temps. Les
+autres notes ont un seul trait ce qui veut dire qu'elles durent un 8e
+de temps. Le silence a aussi deux traits ondulés ce qui veut dire
+qu'il représente aussi un 16e de temps.
+
+Quand on essaie de décoder et d'explorer de nouvelles choses un truc
+très pratique est de rendre tout le plus semblable possible pour
+essayer de voir des relations ou modèles. Par exemple quand on réécrit
+notre notation uniquement en double-croches on peut voir que notre
+notation devient une séquence agréable de notes et de silences.
+
+
+![Habanera Riff 2](../images/tutorial/articles/A.07-bizet/habanera2.png)
+
+# Re-programmer la Habanera
+
+Nous sommes maintenant prêts a traduire cette ligne de basse dans
+Sonic Pi. Encodons ces notes et silences dans un anneau :
+
+    (ring :d, :r, :r, :a, :f5, :r, :a, :r)
+    
+Voyons ce que ça donne. Jetons ça dans une boucle interactive et
+parcourons-là :
+
+    live_loop :habanera do
+      play (ring :d, :r, :r, :a, :f5, :r, :a, :r).tick
+      sleep 0.25
+    end
+    
+Fabuleux, cette mélodie qu'on reconnait immédiatement prend vie dans
+vos haut-parleurs. On a fait des efforts pour en arriver là, mais ça
+valait la peine, bravo !
+    
+# Synthés de mauvaise humeur
+
+Maintenant qu'on a la ligne de basse, essayons de re-créer une partie
+de l'ambiance de la scène d'opéra. Un synthé à essayer est `:blade`
+qui est un synthé style années 80. Essayons le avec la note de départ
+`:d` passée dans un slicer et de la reverb :
+
+    live_loop :habanera do
+      use_synth :fm
+      use_transpose -12
+      play (ring :d, :r, :r, :a, :f5, :r, :a, :r).tick
+      sleep 0.25
+    end
+
+    with_fx :reverb do
+      live_loop :space_light do
+        with_fx :slicer, phase: 0.25 do
+          synth :blade, note: :d, release: 8, cutoff: 100, amp: 2
+        end
+        sleep 8
+      end
+    end
+
+Maintenant essayez les autres notes de la ligne de basse : `:a` et
+`:f5`. Souvenez-vous que vous n'avez pas besoin de cliquer sur 'Stop',
+vous pouvez juste modifier le code pendant que la musique tourne et
+ensuite cliquer sur 'Run' à nouveau. Aussi essayez différentes valeurs
+pour l'option `phase:` du slicer comme `0.5`, `0.75` et `1`.
+
+
+## Rassemblons tout
+
+Enfin, combinons toutes les idées vues jusqu'ici dans un nouveau remix
+de la Habanera. Vous remarquerez peut-être que j'ai inclus une autre
+partie de la ligne de basse en commentaire. Quand vous aurez tout tapé
+dans un buffer de libre cliquez sur 'Run' pour entendre la
+composition. Maintenant, sans cliquer sur 'Stop', *décommentez* la
+seconde ligne en enlevant le `#` et cliquez sur 'Run' à nouveau :
+c'est merveilleux, non ? Maintenant amusez-vous à le modifier vous-même.

+A.8 Devenez un VJ Minecraft
+
+# Devenez un VJ Minecraft
+
+![Screen 0](../images/tutorial/articles/A.08-minecraft-vj/minecraft-vj-0-small.png)
+
+Tout le monde a joué à Minecraft. Vous aurez tous construit des
+structures incroyables, conçu des pièges rusés et même créé des lignes
+de chariots raffinées contrôlées par des interrupteurs de pierre
+rouge. Mais qui parmi vous s'est produit avec Minecraft ? On parie que
+vous ne saviez pas que vous pouvez utiliser Minecraft pour créer des
+animations visuelles incroyables tout comme un VJ professionnel.
+
+Si votre seule possibilité de modifier Minecraft était d'utiliser la
+souris, vous auriez du mal à changer les choses suffisamment vite.
+Heureusement pour vous votre Raspberry Pi a une version de Minecraft
+qui peut être contrôlée avec du code. Il contient aussi une application
+nommée Sonic Pi qui rend la programmation Minecraft non seulement facile
+mais aussi incroyablement amusante.
+
+Dans l'article d'aujourd'hui nous allons vous montrer quelques trucs
+et astuces que nous avons utilisés pour créer des spectacles dans des
+boîtes de nuit et salles de concert autour du monde.
+
+Commençons...
+
+# Commencer
+
+Commençons avec un simple exercice d'échauffement pour nous rappeler
+les bases. Commencez par allumer votre Raspberry Pi et lancer
+Minecraft et Sonic Pi. Dans Minecraft, créez un nouveau monde, et dans
+Sonic Pi choisissez un buffer de libre et écrivez-y ce code :
+
+    mc_message "Let's get started..."
+    
+Cliquez sur le bouton 'Run' et vous verrez le message dans la fenêtre
+Minecraft. OK, on est prêt à démarrer, on va s'amuser...
+
+# Tempêtes de sable
+
+Quand on utilise Minecraft pour créer des visuels on essaie de penser
+à des choses qui auront l'air intéressantes et qui seront aussi
+faciles à générer avec du code. Un truc sympa est de créer une tempête
+de sable en laissant tomber des bloc de sable du ciel. Pour cela on a
+juste besoin de quelques fonctions simples :
+
+* `sleep` : pour insérer un délai entre des actions
+* `mc_location` : pour trouver notre emplacement courant
+* `mc_set_block` : pour positionner des blocs de sable à un endroit particulier
+* `rrand` : pour nous permetre de générer des valeurs aléatoires dans un intervalle
+* `live_loop` : pour nous permettre de faire pleuvoir du sable en continu
+
+<!-- Breakout box start --> 
+
+Si vous ne connaissez pas une des ces fonctions comme `rrand`, vous
+pouvez juste taper le mot dans votre buffer, cliquer dessus, puis
+taper `Control-i` sur le clavier pour ouvrir la documentation. Vous
+pouvez aussi aller dans l'onglet *lang* du système d'aide puis
+y chercher directement les fonctions et toutes sortes d'autres choses
+excitantes que vous pouvez faire.
+
+
+<!-- Breakout box end -->
+
+Commençons par faire tomber un peu de pluie avant de laisser la
+tempête complète éclater. Récupérez votre emplacement courant et
+utilisez-la pour créer quelques blocs de sable dans le ciel pas loin :
+
+    x, y, z = mc_location
+    mc_set_block :sand, x, y + 20, z + 5
+    sleep 2
+    mc_set_block :sand, x, y + 20, z + 6
+    sleep 2
+    mc_set_block :sand, x, y + 20, z + 7
+    sleep 2
+    mc_set_block :sand, x, y + 20, z + 8
+    
+Après avoir cliqué sur 'Run', vous devrez peut-être un peu regarder
+autour de vous car les blocs peuvent commencer par tomber derrière
+vous, suivant dans quelle direction vous êtes pour le moment. N'ayez
+pas peur, si vous les avez raté, cliquez à nouveau sur 'Run' pour
+créer encore un peu de pluie de sable, assurez-vous juste de regarder
+dans la bonne direction.
+
+Parcourons rapidement ce qui se passe ici. Sur la première ligne nous
+avons récupéré l'emplacement Steve en coordonnées avec la fonction
+`mc_location` et les avons placées dans les variables `x`, `y` et `z`.
+Puis sur les lignes suivantes nous avons utilisé la fonction
+`mc_set_block` pour placer un peu de sable aux mêmes coordonnées que
+Steve mais avec quelques modifications. On a utilisé la même
+coordonnée x, une coordonnée y 20 blocs plus haut et des coordonnées z
+successivement plus larges pour que le sable tombe dans une ligne en
+s'éloignant de Steve.
+
+Et si vous preniez ce code et commenciez à jouer avec ? Essayez
+d'ajouter plus de lignes, de changer la durée d'attente, essayez de
+mélanger du `:sand` avec du `:gravel` et choisissez différentes
+coordonnées. Expérimentez et amusez-vous !
+
+# Boucles interactives déchaînées
+
+OK, il est l'heure de lancer la tempête en déchaînant la puissance
+complète de la `live_loop` : la capacité magique de Sonic Pi qui
+montre la puissance entière de la programmation interactive : changer
+le code à la volée pendant qu'il est en train de s'exécuter !
+
+    live_loop :sand_storm do
+      x, y, z = mc_location
+      xd = rrand(-10, 10)
+      zd = rrand(-10, 10)
+      co = rrand(70, 130)
+      synth :cnoise, attack: 0, release: 0.125, cutoff: co
+      mc_set_block :sand, x + xd, y+20, z+zd
+      sleep 0.125
+    end
+    
+Qu'est-ce que c'est amusant ! On boucle assez vite (8 fois par
+seconde) et pendant chaque boucle on trouve l'emplacement de Steve
+comme avant mais on génère ensuite trois valeurs aléatoires :
+
+* `xd` : la différence pour x qui sera entre -10 et 10
+* `zd` : la différence pour z, aussi entre -10 et 10
+* `co` : une valeur de coupure pour le filtre passe-bas, entre 70 et 130
+
+On utilise ensuite ces valeurs aléatoires dans les fonctions `synth`
+et `mc_set_block` ce qui nous donne du sable qui tombe dans des
+endroits aléatoires autour de Steve ainsi qu'un son percussif
+semblable à de la pluie, joué le synthé `:cnoise`.
+
+Pour ceux d'entre vous qui ne connaissaient pas les boucles
+interactives : c'est là qu'on commence vraiment à s'amuser avec Sonic
+Pi. Pendant que le code tourne et que le sable pleut, essayez de
+changer une des valeurs, peut-être la valeur d'attente à `0.25` ou
+le type de bloc `:sand` en `:gravel`. Ensuite cliquez sur 'Run' à
+nouveau. Et voilà ! Les choses changent sans que le code ne s'arrête.
+C'est votre passerelle pour vous produire comme un vrai VJ. Continuez
+à vous exercer à changer des choses. Jusqu'où arrivez-vous à modifier
+les visuels sans arrêter le code ?
+
+
+# Des formes de blocs épiques
+
+![Screen 1](../images/tutorial/articles/A.08-minecraft-vj/minecraft-vj-1-small.png)
+
+Enfin une autre super façon de générer des visuels intéressants est de
+générer des énormes murs de motifs vers lesquels voler. Pour cet effet
+nous allons devoir passer d'un placement aléatoire de blocs à un
+placement de manière ordonnée. On peut faire cela en imbriquant deux
+itérations (cliquez sur le bouton 'Aide' et allez dans la section 5.2
+du tutoriel "Itération et boucles" pour plus d'informations sur
+l'itération). L'étrange `|xd|` après le `do` veut dire que `xd`
+prendra une valeur à chaque boucle de l'itération. La première fois il
+vaudra `0`, puis `1`, puis `2`, etc. En imbriquant deux itérations
+comme cela on peut générer toutes les coordonnées d'un carré. On peut
+ensuite choisir aléatoirement des types de blocs d'un anneau de blocs
+pour obtenir un effet intéressant :
+
+    x, y, z = mc_location
+    bs = (ring :gold, :diamond, :glass)
+    10.times do |xd|
+      10.times do |yd|
+        mc_set_block bs.choose, x + xd, y + yd, z
+      end
+    end
+
+Pas mal. Pendant qu'on s'amuse ici, essayez de changer `bs.choose` en
+`bs.tick` pour passer d'un motif aléatoire à un motif plus régulier.
+Essayez de changer les types de blocs et les plus aventureux parmi
+vous voudrons peut-être mettre ce code dans une `live_loop` pour que
+les modifs continuent à changer automatiquement.
+
+Enfin, pour la fin du set du VJ, changez les deux `10.times` en
+`100.times` et cliquez sur 'Run'. Boum ! Un énorme mur géant de
+briques aléatoires. Imaginez combien de temps ça vous aurait pris de
+construire ça avec votre souris ! Double-tapez la touche Espace pour
+entrer en mode volant et commencez à planer pour obtenir de super
+effets visuels. Ne vous arrêtez pas là, utilisez votre imagination 
+pour trouver des idées sympa et utilisez ensuite la puissance de
+programmation de Sonic Pi pour le réaliser. Quand vous vous serez
+suffisamment exercés, baissez la lumière et donnez un spectacle de VJ
+pour vos amis !

+A.9 L'aléatoire
+
+# Surfer sur des flux aléatoires
+
+Dans le quatrième épisode de cette série de tutoriels nous avons jeté
+un oeil brièvement à l'aléatoire en codant des riffs grésillants de
+synthé. Vu comme l'aléatoire est une partie très importante de mes
+performances de live coding j'ai pensé qu'il serait utile d'en couvrir
+les bases plus en détail. Mettez votre casquette et surfons sur des
+flux aléatoires !
+
+# Il n'y a pas d'aléatoire
+
+La première chose à apprendre qui pourrait vraiment vous surprendre en
+jouant avec les fonctions aléatoires de Sonic Pi c'est qu'elles ne
+sont en fait pas vraiment aléatoires. Qu'est-ce que cela signifie ?
+Eh bien, faisons quelques essais. Commencez par imaginer un nombre
+dans votre tête entre 0 et 1. Gardez-le en tête et ne me le dites pas.
+Maintenant, laissez-moi deviner... est-ce que c'était `0.321567` ?
+Non ? Bah, je ne suis clairement pas bon à ce jeu. Essayons encore une
+fois, mais demandons à Sonic Pi de choisir un nombre cette fois.
+Lancez Sonic Pi version 2.7 ou plus et demandez lui un nombre
+aléatoire mais de nouveau ne me dites pas le résultat.
+
+
+    print rand
+    
+Et maintenant pour le truc... est-ce que c'était `0.75006103515625` ?
+Oui ! Ha, je vois que vous êtes un peu sceptique. C'était peut-être
+juste de la chance. Essayons encore. Cliquez sur 'Run' à nouveau et
+regardons ce qu'on obtient... Quoi ? Encore `0.75006103515625` ? Ca ne
+peut clairement pas être aléatoire ! Vous avez raison, ça ne l'est pas.
+
+Qu'est-ce qui se passe ici ? Le mot savant d'informatique pour ceci
+est le déterminisme. Cela veut juste dire que rien n'a lieu par hasard
+et que tout a sa destinée. Votre version de Sonic Pi a le destin de
+toujours retourner `0.75006103515625` dans le programme ci-dessus.
+Cela peut sembler assez inutile, mais laissez moi vous assurer que
+c'est une des parties les plus puissantes de Sonic Pi. Si vous
+persévérez vous apprendrez comment compter sur la nature
+déterministique de l'aléatoire dans Sonic Pi comme un bloc de
+construction fondamental pour vos compositions et performances de live
+coding.
+
+# Une mélodie aléatoire
+
+Quand Sonic Pi démarre il charge en fait en mémoire une séquence de
+441 000 valeurs aléatoires pré-générées. Quand vous appelez une
+fonction aléatoire comme `rand` ou `rrand`, ce flux aléatoire est
+utilisé pour générer votre résultat. Chaque appel à une fonction
+aléatoire consomme une valeur de ce flux. Ainsi le dixième appel à une
+fonction aléatoire utilisera la dixième valeur du flux. Aussi, chaque
+fois que vous cliquez sur le bouton 'Run', le flux est réinitialisé
+pour cette exécution. C'est pour cela que j'ai pu prédire le résultat
+de `rand` et pourquoi la mélodie 'aléatoire' était la même à chaque
+fois. La version de Sonic Pi de chacun utilise exactement le même flux
+aléatoire ce qui est très important quand on commence à partager nos
+morceaux.
+
+Utilisons cette connaissance pour générer une mélodie aléatoire
+répétable :
+
+    8.times do
+     play rrand_i(50, 95)
+     sleep 0.125
+    end
+
+Tapez ceci dans un buffer de libre et cliquez sur 'Run'. Vous
+entendrez une mélodie de notes aléatoires entre 50 et 95. Quand elle
+aura fini, cliquez sur 'Run' à nouveau pour entendre exactement la
+même mélodie à nouveau.
+
+*start breakout box*
+## Des fonctions aléatoires pratiques
+
+Sonic Pi contient un certain nombre de fonctions utiles pour
+travailler avec le flux aléatoire. Voici une liste des plus utiles :
+
+* `rand` : retourne simplement la prochaine valeur dans le flux aléatoire
+* `rrand` : retourne une valeur aléatoire dans un intervalle
+* `rrand_i` : retourne une valeur entière aléatoire dans un intervalle
+* `one_in` : retourne vrai ou faux pour une probabilité donnée
+* `dice` : imite un jet de dé et retourne une valeur entre 1 et 6
+* `choose` : choisit une valeur aléatoire dans une liste
+
+Regardez leur documentation dans le système d'aide pour des
+informations détaillées et des exemples.
+
+ *end breakout box*
+
+# Réinitialiser le flux
+
+Même si la capacité de répéter une séquence de notes choisies est
+essentielle pour vous permettre de rejouer une mélodie sur la piste de
+danse, ça pourrait ne pas être exactement la mélodie que vous
+souhaitez. Ne serait-ce pas génial si on pouvait essayez différentes
+mélodies et choisir celle qu'on préfère ? C'est ici que la vraie
+magie commence.
+
+On peut régler le flux manuellement avec la fonction
+`use_random_seed`. En informatique, une graine aléatoire est le point
+de départ à partir duquel un nouveau flux de valeurs aléatoires peut
+fleurir. Essayons-le :
+
+
+    use_random_seed 0
+    3.times do
+      play rrand_i(50, 95)
+      sleep 0.125
+    end
+    
+Super, on récupère les trois premières notes de notre mélodie
+aléatoire ci-dessus : `84`, `83` et `71`. Cependant on peut
+maintenant changer la graine. Par exemple :
+
+    use_random_seed 1
+    3.times do
+      play rrand_i(50, 95)
+      sleep 0.125
+    end
+    
+    
+Intéressant, on obtient `83`, `71` et `61`. Vous avez peut-être
+remarqué que les deux premiers nombres ici sont les mêmes que les deux
+derniers nombres d'avant : ce n'est pas une coïncidence.
+
+Rappelez-vous que le flux aléatoire est juste une liste géante de
+valeurs pré-choisies. Choisir une graine aléatoire nous déplace juste
+en un point de la liste. Une autre manière de voir ça est d'imaginer
+un énorme jeu de cartes pré-mélangées. Utiliser une graine aléatoire,
+c'est couper le jeu en un point particulier. Ce qui est fabuleux avec
+ça c'est qu'on peut se déplacer dans le flux aléatoire, ce qui nous
+donne un énorme pouvoir quand on fait de la musique.
+
+Revisitons notre mélodie aléatoire de huit notes avec cette nouvelle
+capacité de réinitialiser le flux, et mettons là dans une boucle
+interactive pour pouvoir expérimenter pendant qu'elle joue :
+
+    live_loop :random_riff do    
+      use_random_seed 0
+      8.times do
+        play rrand_i(50, 95), release: 0.1
+        sleep 0.125
+      end
+    end
+
+Maintenant, pendant qu'elle est en train de jouer, changez la valeur
+de la graine de `0` en quelque chose d'autre. Essayez `100`, ou
+pourquoi pas `999`. Essayez vos propres valeurs, expérimentez et
+amusez-vous : voyez quelle graine génère la mélodie que vous préférez.
+
+# Rassemblons tout
+
+Le tutoriel de ce mois a été un plongeon bien technique dans les 
+entrailles de la fonctionnalité aléatoire de Sonic Pi. J'espère que
+cela vous a montré un peu comment elle marche et comment vous pouvez
+commencer à utiliser de l'aléatoire de manière fiable pour créer des
+motifs reproductibles dans votre musique. Il est important de souligner
+qu'on peut utiliser de l'aléatoire reproductible *où* on veut. Par
+exemple, on peut rendre aléatoire l'amplitude des notes, le mix d'un
+effet, etc. Dans l'avenir nous regarderons de plus près certaines de
+ces applications, mais pour le moment je vais vous laisser avec un
+exemple court.
+
+Tapez le code suivant dans un buffer disponible, cliquez sur 'Run' et
+commencez à modifier les graines, cliquez sur 'Run' de nouveau
+(pendant que le code tourne) et explorez les différents sons, rythmes
+et mélodies que vous pouvez créer. Quand vous en trouvez une qui sonne
+bien, notez la graine pour pouvoir y revenir plus tard. Enfin, quand
+vous aurez trouvé quelques graines qui vous plaisent, donnez un
+concert de live coding à vos amis en changeant simplement entre vos
+graines préférées pour créer un morceau entier.

+A.10 Contrôle
+
+# Contrôler votre son
+
+Jusqu'ici dans cette série nous nous sommes concentrés sur le
+déclenchement de sons. Nous avons découvert qu'on pouvait déclencher
+les nombreux synthés présents dans Sonic Pi avec `play` ou `synth` et
+comment déclencher des samples pré-enregistrés avec `sample`. Nous
+avons aussi vu comment on pouvait entourer ces sons dans des effets
+studio tels que la reverb et la distorsion en utilisant la commande
+`with_fx`. En combinant cela avec le système de chronométrage
+incroyablement précis de Sonic Pi on peut produire un vaste ensemble
+de sons, rythmes et mélodies. Cependant, une fois qu'on a
+soigneusement sélectionné les options d'un son en particulier et qu'on
+l'a déclenché, on ne peut plus le modifier pendant qu'il est joué,
+c'est ça ? Non ! Aujourd'hui vous allez apprendre quelque chose de
+très puissant : comment contrôler des synthés qui sont en train d'être
+joués.
+
+## Un son de base
+
+Créons un simple son agréable. Lancez Sonic Pi et tapez le code
+suivant dans un buffer disponible :
+
+```
+synth :prophet, note: :e1, release: 8, cutoff: 100
+```
+
+Maintenant cliquez sur le bouton 'Run' en haut à gauche pour entendre
+un beau son de synthé grondant. Allez-y, cliquez à nouveau dessus
+quelques fois pour vous habituer. OK, fini? Commençons à le contrôler !
+
+## Noeuds de synthé
+
+Une fonctionnalité peu connue de Sonic Pi est que les fonctions
+`play`, `synth` et `sample` retournent ce qu'on appelle un `SynthNode`
+qui représente un son en train d'être joué. Vous pouvez capturer un de
+ces `SynthNode`s en utilisant une variable standard et le *contrôler*
+ensuite dans le futur. Par exemple, changeons la valeur de l'option
+`cutoff:` après un battement :
+
+```
+sn = synth :prophet, note: :e1, release: 8, cutoff: 100
+sleep 1
+control sn, cutoff: 130
+```
+
+Regardons chaque ligne une par une :
+
+On commence par déclencher le synthé `:prophet` en utilisant la
+fonction `synth` habituelle. Cependant on capture aussi le résultat
+dans une variable nommée `sn`. On aurait pu appeler cette variable
+complètement différemment comme par exemple `synth_node` ou `jane` :
+le nom n'a pas d'importance. Enfin il est important de choisir un nom
+qui a du sens pour vous pour vos performances et pour les gens qui
+lisent votre code. J'ai choisi `sn` parce que c'est un bon petit moyen
+mnémotechnique pour 'synth node'.
+
+A la ligne 2 on a une commande `sleep` standard. Ca ne fait rien de
+spécial : ça demande juste à l'ordinateur d'attendre un battement
+avant d'avancer à la ligne suivante.
+
+C'est à la ligne 3 qu'on commence à s'amuser. Ici on utilise la
+fonction `control` pour dire à notre `SynthNode` courant de changer la
+valeur de coupure en `130`. Si vous cliquez sur le bouton 'Run', vous
+entendrez le synthé `:prophet` commencer à jouer comme avant, mais
+après un battement il changera et sonnera beaucoup plus clair.
+
+
+** Breakout Box Start **
+Options modulables
+
+La plupart des options des synthés et effets de Sonic Pi peuvent être
+modifiées après avoir été déclenchées. Cependant, ce n'est pas le cas
+pour toutes. Par exemple, les options d'enveloppe `attack:`, `decay:`,
+`sustain:` et `release:` ne peuvent être définies que quand on
+déclenche le synthé. Pour savoir quelles options peuvent être
+modifiées ou non, c'est simple : allez voir la documentation d'un
+synthé ou effet et regardez la documentation des options individuelles
+et cherchez les phrases "May be changed whilst playing" (Peut être
+modifiée en jouant) ou "Can not be changed once set" (ne peut pas être
+modifiée une fois définie). Par exemple, la documentation de l'option
+`attack:` du synthé `:beep` indique clairement qu'on ne peut pas la
+modifier ultérieurement :
+
+* Valeur par défaut: 0 
+* Doit être supérieure ou égal à 0
+* Ne peut pas être modifiée après sa définition
+* Mise à l'échelle avec la valeur courante de BPM
+** Breakout Box End **
+
+## Modifications multiples
+
+Pendant qu'un synthé est joué vous n'êtes pas limités à ne le changer
+qu'une fois : vous êtes libres de le modifier autant que vous le
+souhaitez. Par exemple, on peut transformer notre `:prophet` en petit
+arpégiateur avec le code suivant :
+
+```
+notes = (scale :e3, :minor_pentatonic)
+sn = synth :prophet, note: :e1, release: 8, cutoff: 100
+sleep 1
+16.times do
+  control sn, note: notes.tick
+  sleep 0.125
+end
+```
+
+Dans cet extrait de code nous avons juste introduit quelques choses en
+plus. On commence par définir une nouvelle variable appelée `notes`
+qui contient les notes qu'on aimerait parcourir en boucle (un
+arpégiateur est juste un mot savant pour quelque chose qui parcourt en
+boucle une liste de notes dans un ordre donné). Ensuite on déplace
+notre appel à `control` dans une itération en l'appelant 16 fois. A
+chaque appel à `control` on parcourt notre anneau de `notes` qui va se
+répéter automatiquement quand on arrivera à sa fin (grâce à la
+puissance fabuleuse des anneaux de Sonic Pi). Pour un peu de variété
+essayez de remplacer `.tick` par `.choose` et tentez d'entendre la
+différence.
+
+
+Notez qu'on peut modifier plusieurs options en même temps. Essayez de
+changer la ligne de contrôle en la suivante et écoutez la différence :
+
+```
+control sn, note: notes.tick, cutoff: rrand(70, 130)
+```
+
+## Transitions
+
+Quand on contrôle un `SynthNode`, il répond exactement à ce moment-là
+et change immédiatement la valeur de l'option comme si vous aviez
+pressé un bouton ou actionné un interrupteur pour demander la
+modification. Cela peut sonner rythmique et percussif, notamment si
+l'option contrôle un aspect du timbre comme `cutoff:`. Cependant, on
+n'a pas toujours envie que la modification arrive immédiatement. On a
+parfois envie de se déplacer en douceur de la valeur courante à la
+nouvelle, comme si on avait déplacé un curseur. Bien sûr, Sonic Pi
+sait aussi faire cela en utilisant les options `_slide:`
+
+Chaque option qui peut être modifiée a aussi une option spéciale
+correspondante `_slide:` qui vous permet de définir un temps de
+transition. Par exemple, `amp:` a `amp_slide:` et `cutoff:` a
+`cutoff_slide:`. Ces options de transition marchent un peu
+différemment de toutes les autres options parce qu'elles disent à la
+note de synthé comment se comporter *la prochaine fois qu'elle seront
+contrôlées*. Voyons ça :
+
+```
+sn = synth :prophet, note: :e1, release: 8, cutoff: 70, cutoff_slide: 2
+sleep 1
+control sn, cutoff: 130
+```
+
+Remarquez que cet exemple est exactement le même qu'avant sauf qu'on a
+ajouté `cutoff_slide:`. Ceci indique que la prochaine fois que
+l'option `cutoff:` de ce synthé sera contrôlée, il mettra deux
+battements pour passer de sa valeur courante à la nouvelle valeur.
+Par conséquent, quand on utilise `control` vous pouvez entendre la
+coupure changer graduellement de 70 à 130. Cela crée une sensation
+dynamique intéressante pour le son. Maintenant essayez de changer la
+durée de `cutoff_slide:` en une valeur plus courte comme 0.5 ou une
+valeur plus longue comme 4 pour voir comment ça change le son.
+Souvenez-vous que vous pouvez transitionner chacune des options
+modifiables de cette même manière, et chaque valeur de `_slide:` peut
+être complètement différente donc vous pouvez avoir une transition
+lente de la coupure, une transition rapide de l'amplitude, et une
+transition de la stéréo un peu entre les deux si c'est ce que vous
+avez envie de créer.
+
+
+## Rassemblons tout
+
+Regardons un court exemple qui montre la puissance du contrôle des
+synthés après leur déclenchement. Remarquez que vous pouvez aussi
+transitionner les effets comme les synthés, mais avec une syntaxe
+légèrement différente. Regardez la section 7.2 du tutoriel inclus dans
+Sonic Pi pour plus d'information sur le contrôle des effets.
+
+Copiez le code dans un buffer de libre et écoutez. Ne vous arrêtez pas
+là : jouez à modifier le code. Changez les durées de transition,
+changez les notes, le synthé, l'effet et les durées d'attente et voyez
+si vous pouvez le transformer en quelque chose de complètement
+différent !
+
+
+```
+live_loop :moon_rise do
+  with_fx :echo, mix: 0, mix_slide: 8 do |fx|
+    control fx, mix: 1
+    notes = (scale :e3, :minor_pentatonic, num_octaves: 2).shuffle
+    sn = synth :prophet , sustain: 8, note: :e1, cutoff: 70, cutoff_slide: 8
+    control sn, cutoff: 130
+    sleep 2
+    32.times do
+      control sn, note: notes.tick, pan: rrand(-1, 1)
+      sleep 0.125
+    end
+  end
+end
+```

+A.11 Tic tac
+
+# Suivre le rythme
+
+Le mois dernier dans cette série nous avons regardé en détail comment
+fonctionne le système de gestion de l'aléatoire de Sonic Pi. On a
+exploré comment on peut l'utiliser de manière déterministe pour avoir
+de nouveaux niveaux de contrôle dynamique sur notre code. Ce mois-ci
+nous allons continuer notre exploration technique et regarder le
+système unique de 'tick' de Sonic Pi. D'ici la fin de cet article vous
+parcourrez des rythmes et mélodies sur votre chemin pour devenir un DJ
+de programmation interactive.
+
+
+# Compter les temps
+
+Quand on fait de la musique on a souvent envie de faire quelque chose
+de différent en fonction du temps sur lequel on est. Sonic Pi a un
+système spécial pour compter les temps appelé `tick` pour vous donner
+un contrôle précis sur quand est-ce qu'un battement arrive réellement
+et il supporte même des battements multiples avec leur propre tempo.
+
+Amusons-nous : pour avancer le temps on a juste besoin d'appeler
+`tick`. Ouvrez un buffer libre, tapez le code suivant et cliquez sur
+le bouton 'Run' :
+
+```
+puts tick #=> 0
+```
+
+Cela retournera le battement courant : `0`. Remarquez que même si
+vous cliquez plusieurs fois sur le bouton 'Run', il retournera
+toujours `0`. Cela parce que chaque exécution commence avec un
+compteur qui part de 0. Cependant, pendant que le programme tourne, on
+peut avancer le compteur autant qu'on veut :
+
+```
+puts tick #=> 0
+puts tick #=> 1
+puts tick #=> 2
+```
+
+<breakout> Quand vous voyez le symbole `#=>` à la fin d'une ligne de
+code cela veut dire que cette ligne va noter ce texte dans la partie
+de droite de Sonic Pi. Par exemple, `puts foo #=> 0` veut dire que le
+code `puts foo` affiche `0` dans le log à cet endroit du programme.
+</breakout>
+
+# Vérifier le compteur
+
+On a vu que `tick` fait deux choses. Il incrémente (ajoute un) et
+retourne le compteur courant. Parfois on veut juste regarder le
+battement courant sans devoir l'incrémenter et on peut faire cela via
+`look`.
+
+``` 
+puts tick #=> 0
+puts tick #=> 1
+puts look #=> 1
+puts look #=> 1
+``` 
+
+Dans ce code on incrémente le compteur deux fois puis on appelle
+`look` deux fois. On verra les valeurs suivantes dans le log : `0`,
+`1`, `1`, `1`. Les deux premiers `tick`s ont retourné `0` et `1`,
+comme attendu, puis les deux `look`s ont juste retourné la dernière
+valeur du compteur deux fois, donc `1`.
+
+
+# Anneaux
+
+On peut donc avancer le compteur avec `tick` et en connaître la valeur
+avec `look`. Qu'est-ce qui vient suite ? On a besoin de quelque chose
+à parcourir. Sonic Pi utilise les anneaux pour représenter les
+mélodies et rythmes et le système de tick a été conçu spécialement
+pour fonctionner avec eux. En fait, les anneaux ont leur propre
+version de `tick` qui fait deux choses. D'un côté elle agit comme un
+tick normal et incrémente le compteur. D'un autre, elle donne une
+valeur de l'anneau en utilisant le compteur comme index. Voyons cela :
+
+```
+puts (ring :a, :b, :c).tick #=> :a
+```
+
+`.tick` est une version spéciale avec un point de `tick` qui nous
+retourne la première valeur de l'anneau: : `:a`. On peut attraper
+chacune des notes de l'anneau en appelant `:tick` plusieurs fois :
+
+```
+puts (ring :a, :b, :c).tick #=> :a
+puts (ring :a, :b, :c).tick #=> :b
+puts (ring :a, :b, :c).tick #=> :c
+puts (ring :a, :b, :c).tick #=> :a
+puts look                   #=> 3
+```
+
+Regardez le log et vous verrez `:a`, `:b`, `:c` et puis de nouveau
+`:a`. Remarquez que `look` retourne `3`. Les appels à `.tick` se
+comportent comme les appels à `tick` : ils incrémentent le compteur
+local.
+
+
+# Un arpégiateur dans une boucle interactive
+
+La véritable puissance vient quand on mélange `tick` avec des anneaux
+et des `live_loop`s. En les combinant on a tous les outils dont on a
+besoin pour construire et comprendre un arpégiateur simple. On a juste
+besoin de quatre choses :
+
+1. Un anneau qui contient les notes sur lesquelles on va boucler
+2. Une manière d'incrémenter et de lire le compteur
+3. La capacité de jouer une note en se basant sur le compteur courant
+4. Une structure de boucle qui répète l'arpégiateur en continu
+
+Ces concepts se retrouvent tous dans le code suivant :
+
+```
+notes = (ring 57, 62, 55, 59, 64)
+
+live_loop :arp do
+  use_synth :dpulse
+  play notes.tick, release: 0.2
+  sleep 0.125
+end
+```
+
+Regardons chacune de ces lignes. On commence par définir notre anneau
+de notes que nous allons jouer en continu. On crée ensuite une
+`live_loop` nommée `:arp` qui va boucler pour nous. A chaque itération
+de la `live_loop` on choisit un synthé `:dpulse` et on joue ensuite la
+note suivante de notre anneau en utilisant `.tick`. Souvenez-vous que
+cela va incrémenter notre compteur de temps et en utiliser la valeur
+comme index dans notre anneau de notes. Enfin on attend un huitième de
+temps avant de recommencer la boucle.
+
+# Battements multiples simultanés
+
+Une chose très importante à savoir est que les `tick`s sont liés à la
+`live_loop`. Cela veut dire que chaque `live_loop` a son propre
+compteur indépendant. C'est beaucoup plus puissant que d'avoir un
+métronome et battement global. Regardons ce que cela donne :
+
+notes = (ring 57, 62, 55, 59, 64)
+
+with_fx :reverb do
+  live_loop :arp do
+    use_synth :dpulse
+    play notes.tick + 12, release: 0.1
+    sleep 0.125
+  end
+end
+
+live_loop :arp2 do
+  use_synth :dsaw
+  play notes.tick - 12, release: 0.2
+  sleep 0.75
+end
+
+# Collisions de battements
+
+Une grande source de confusion dans le système de tick de Sonic Pi est
+quand on veut parcourir plusieurs anneaux dans le même `live_loop`.
+
+use_bpm 300
+use_synth :blade
+live_loop :foo do
+  play (ring :e1, :e2, :e3).tick
+  play (scale :e3, :minor_pentatonic).tick
+  sleep 1
+end
+
+Même si chaque `live_loop` a son compteur indépendant, ici on appelle
+`.tick` deux fois dans la même `live_loop`. Cela veut dire que le
+compteur sera incrémenté deux fois à chaque boucle. Cela peut produire
+des polyrythmes intéressants mais ce n'est souvent pas ce que l'on
+souhaite. Il y a deux solutions à ce problème. Une option est
+d'appeler `tick` manuellement au début de la `live_loop` puis
+d'utiliser `look` pour chercher la valeur courante du compteur dans
+chaque `live_loop`. La seconde solution est de passer un nom unique
+à chaque appel à `.tick`, comme par exemple `.tick(:foo)`. Sonic Pi
+créera alors un compteur séparé pour chaque tick nommé que vous
+utiliserez. Ainsi on peut travailler avec autant de compteurs que
+nécessaire ! Lisez le section 9.4 sur les ticks nommés dans le
+tutoriel inclus dans Sonic Pi pour plus d'informations.
+
+# Rassemblons tout
+
+Combinons nos connaissances sur les `tick`s, `ring`s (anneaux) et
+`live_loop`s pour un dernier exemple amusant. Comme d'habitude, ne
+traitez pas ceci comme un morceau terminé. Commencez à changer des
+choses et amusez-vous avec et voyez en quoi vous pouvez le
+transformer. A la prochaine...

 つまり要約すると、Sonic PiのADSRエンベロープには、以下のフェーズがあります。
 
 1. *attack*（アタック）- 0 アンプから`attack_level`までの時間
-2. *decay*（ディケイ）- 音量を`attack_level`から`sustain_level`まで移行させる時間
-3. *sustain*（サステイン）- 音量を`sustain_level`で保持する時間
+2. *decay*（ディケイ）- 音量を`attack_level`から`decay_level`まで移行させる時間
+3. *sustain*（サステイン）- 音量を`decay_level`から`sustain_level`まで移行させる時間
 4. *release*（リリース） - 音量を`sustain_level`から 0 に移行させる時間
 
 サウンドのデュレーションは、これらのフェーズの合計であることに注意することが大切です。
 したがって、以下のサウンドは 0.5 + 1 + 2 + 0.5 = 4 で、4秒のデュレーションになります。

+8.5 リングのチェーン
+
+`range`や`spread`のようなコンストラクタに加えて、別なリングの作成方法としては、作成済みのリングを操作する方法があります。
+
+## チェーンコマンド
+
+次のような単純なリングを作成します:
+
+```
+(ring 10, 20, 30, 40, 50)
+```
+
+リングを逆にしたいときにはどうしたらよいでしょう？リングを反転させるには、チェーンコマンドの`.reverse`を使います:
+
+```
+(ring 10, 20, 30, 40, 50).reverse  #=> (ring 50, 40, 30, 20, 10)
+```
+
+では次に、リングから最初の3つの値を取得するにはどうしたらよいでしょう？
+
+```
+(ring 10, 20, 30, 40, 50).take(3)  #=> (ring 10, 20, 30)
+```
+
+最後に、リングをシャッフルするにはどうしたらよいでしょう？
+
+```
+(ring 10, 20, 30, 40, 50).shuffle  #=> (ring 40, 30, 10, 50, 20)
+```
+
+## 多重チェーン
+
+ここまでで既に強力なリングの作成方法を見てきましたが、
+これらのコマンドを一緒に用いることで本当の力を発揮します。
+
+リングをシャッフルし、最初の要素を削除し、次の3つの要素を得る場合にはどうでしょう？
+
+段階的に見ていきましょう:
+
+1. `(ring 10, 20, 30, 40, 50)` - リングの最初の状態
+2. `(ring 10, 20, 30, 40, 50).shuffle` - シャッフルし - `(ring 40, 30, 10, 50, 20)`
+3. `(ring 10, 20, 30, 40, 50).shuffle.drop(1)` - 最初の要素を削除し - `(ring 30, 10, 50, 20)`
+4. `(ring 10, 20, 30, 40, 50).shuffle.drop(1).take(3)` - 3つの要素を得る - `(ring 30, 10, 50)`
+
+*コマンドを一緒にくっつける*だけでこれらのコマンドの長いチェーンを作ることが分かったと思います。
+チェーンコマンドを好きな順序で組み合わせることができ、それにより既に存在するリングから新しいリングを
+生成するとても豊かで強力な方法を作り出しています。
+
+## 不変性
+
+リングは強力で重要な特徴を持っています。それは不変性と言って、リングを変更できないということを
+意味しています。このセクションで紹介しているチェインコマンドが*リングを変更するのではなく*、
+*新しいリングを作成*していることを意味しています。これにより、スレッドを跨いでリングを共有して、
+同じリングを使っている他のスレッドに影響を与えないで、チェインを開始できることを意味しています。
+
+## 利用可能なチェーンコマンド
+
+ここに利用可能なチェーンコマンドを記載しておきます。
+
+* `.reverse` - 逆順のリングを返却します
+* `.sort`    - ソートされたリングを作成します
+* `.shuffle` - シャッフルされたリングを作成します
+* `.take(5)` - 最初の5つの要素をのみからなる新しいリングを返却します
+* `.drop(3)` - 最初の3つの要素以外の要素からなる新しいリングを返却します
+* `.butlast` - 最後の要素が欠けた状態の新しいリングをを返却します
+* `.drop_last(3)` - 最後の3つの要素が欠けた状態の新しいリングをを返却します
+* `.take_last(6)`- 最後の6つの要素をのみからなる新しいリングを返却します
+* `.stretch(2)` - リングの個々の要素を2回ずつ繰り返します
+* `.repeat(3)` - リング全体を3回繰り返します
+* `.mirror` - 逆順のリングを自分自身に追加します
+* `.reflect` - mirrorと同様ですが、真ん中の要素を重複させないようにします
+
+数字を引数に取っているチェーンコマンドは、他の数字を取ることももちろん可能です。
+最初の5個の要素を削除したい場合には、`.drop(3)`の代わりに遠慮無く`.drop(5)`を呼んでください。

+9.4 チック
+
+# チック
+
+ライブコーディングでリングをループしていて、気が付くとたくさんのことをしていたことはないでしょうか。
+例えば、リングにメロディーの音符を入れたり、リズムのスリープ、
+コード進行や音色のバリエーションを入れたり等々。
+
+## リングのチック
+
+Sonic Piは`live_loop`内でリングと共に使える*とても*手軽なツールを提供しています。
+それはチックシステムと呼ばれ、*tick through rings（リングをチックタックと進める）*
+機能を提供しています。次の例を見てください。
+
+```
+live_loop :arp do
+  play (scale :e3, :minor_pentatonic).tick, release: 0.1
+  sleep 0.125
+end
+```
+
+ここでは、E3マイナーペンタトニックのスケールを作成し、各要素をチックしています。これは`.tick`を
+スケール宣言の末尾に追加することによって実現されています。このチックはライブループ内で局所的であるため、
+個々のライブループは独立したチックを持つことができます。
+
+```
+live_loop :arp do
+  play (scale :e3, :minor_pentatonic).tick, release: 0.1
+  sleep 0.125
+end
+
+live_loop :arp2 do
+  use_synth :dsaw
+  play (scale :e2, :minor_pentatonic, num_octaves: 3).tick, release: 0.25
+  sleep 0.25
+end
+```
+
+## 標準関数としてのチック
+
+`tick`はまた標準関数としても呼ぶことができ、その値はインデックスとして使うことができます。
+
+```
+live_loop :arp do
+  idx = tick
+  play (scale :e3, :minor_pentatonic)[idx], release: 0.1
+  sleep 0.125
+end
+```
+
+しかし、この場合は`.tick`を呼ぶほうが良いでしょう。`tick`関数の用途は、
+チックの値で手の込んだことをしたかったり、リングのインデックス以外のことにチックの値を使いたかったりする場合です。
+
+## ルック
+
+チックの魅力的なところはそれが新しいインデックス（もしくはそのインデックスにあるリングの値）
+を返すだけでなく、次にチックを呼んだときに必ず次の値を返すことを保証していることでしょう。
+`tick`が色んな形でこのような動作をしていることをこのドキュメントの例で見てみてください。
+しかし、ここでチックの現在の値を見たいだけで値を*増加させたくない*の場合もあることを指摘することは重要でしょう。
+これは`look`関数により実現可能です。`look`を標準関数として呼んだり、リングの後ろに`.look`を付けたりできます。
+
+## チックの名前付け
+
+最後に、1つのライブループに複数のチックが必要になることがあるかも
+しれません。これはチックに名前を付けることで実現できます。
+
+```
+live_loop :arp do
+  play (scale :e3, :minor_pentatonic).tick(:foo), release: 0.1
+  sleep (ring 0.125, 0.25).tick(:bar)
+end
+```
+
+ここでは2つのチックを使っていて、1つは音符用に、1つはスリープ時間用にしています。
+これらのチックは同じライブループにあるので、別々にしておくためにユニークな名前を与えています。
+これはちょうど`live_loop`に名前を付ける（`:`から始まるシンボル名を渡すだけ）のと同じことです。
+上の例では1つは`:foo`でチックを呼び出し、もう1つは`:bar`で呼び出しています。
+また、これらの値を`look`したい場合には、チックの名前を`look`に渡す必要があります。
+
+## 複雑にしすぎないように
+
+チックシステムの能力のほどんどは、最初のうちは役に立たないでしょう。
+このセクションの全ての内容を学習しようとしないでください。
+一つのリングでチックすることだけに集中するとよいでしょう。
+そうすることで、`live_loop`でリングをチックする簡単さや楽しみを得ることができるでしょう。
+
+`tick`のドキュメントには役に立つ例がたくさんあるので、それを見て楽しくチックしてみましょう！

+3.7 Sample Packs
+
+# Sample Packs
+
+**Note: this section of the tutorial covers the advanced topic of
+working with large directories of your own samples. This will be the
+case if you've downloaded or bought your own sample packs and wish to
+use them within Sonic Pi.**
+
+**Feel free to skip this if you're happy working with the built-in
+samples.**
+
+When working with large folders of external samples it can be cumbersome
+to have to type the whole path every time to trigger an individual
+sample.
+
+For example, say you have the following folder on your machine:
+
+```
+/path/to/my/samples/
+```
+
+When we look inside that folder we find the following samples:
+
+* `100_A#_melody1.wav`
+* `100_A#_melody2.wav`
+* `100_A#_melody3.wav`
+* `120_A#_melody4.wav`
+* `120_Bb_guit1.wav`
+* `120_Bb_piano1.wav`
+
+Typically in order to play the piano sample we can use the full path:
+
+```
+sample "/path/to/my/samples/120_Bb_piano1.wav"
+```
+
+If we want to then play the guitar sample we can use its full path too:
+
+```
+sample "/path/to/my/samples/120_Bb_guit.wav"
+```
+
+However, both of these calls to sample requires us to *know* the names
+of the samples within our directory. What if we just want to listen to
+each sample in turn quickly? 
+
+## Indexing Sample Packs
+
+If we want to play the first sample in a directory we just need to pass
+the directory's name to `sample` and the index `0` as follows:
+
+```
+sample "/path/to/my/samples/", 0
+```
+
+We can even make a shortcut to our directory path using a variable:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, 0
+```
+
+Now, if we want to play the second sample in our directory, we just need
+to add 1 to our index:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, 1
+```
+
+Notice that we no longer need to know the names of the samples in the
+directory - we just need to know the directory itself (or have a
+shortcut to it). If we ask for an index which is larger than the number
+of samples, it simply wraps round just like Rings. Therefore, whatever
+number we use we're guaranteed to get one of the samples in that
+directory.
+
+## Filtering Sample Packs
+
+Ususally indexing is enough, but sometimes we need more power to sort
+and organise our samples. Luckily many sample packs add useful
+information in the filenames. Let's take another look at the sample file
+names in our directory:
+
+* `100_A#_melody1.wav`
+* `100_A#_melody2.wav`
+* `100_A#_melody3.wav`
+* `120_A#_melody4.wav`
+* `120_Bb_guit1.wav`
+* `120_Bb_piano1.wav`
+
+Notice that in these filenames we have quite a bit of
+information. Firstly, we have the BPM of the sample (beats per minute)
+at the start. So, the piano sample is at 120 BPM and our first three
+melodies are at 100 BPM. Also, our sample names containtain the key. So
+the guitar sample is in Bb and the melodies are in A#. This information
+is very useful for mixing in these samples with our other code. For
+example, we know we can only play the piano sample with code that's in
+120 BPM and in the key of Bb.
+
+It turns out that we can use this particular naming convention of our
+sample sets in the code to help us filter out the ones we want. For
+example, if we're working at 120 BPM, we can filter down to all the
+samples that contain the string `"120"` with the following:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120"
+```
+
+This will play us the first match. If we want the second match we just
+need to use the index:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120", 1
+```
+
+We can even use multiple filters at the same time. For example, if we
+want a sample that's filename contains both the substring "120" and "A#"
+we can find it easily with the following code:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120", "A#"
+```
+
+Finally, we're still free to add our usual opts to the call to `sample`:
+
+```
+samps = "/path/to/my/samples/"
+sample samps, "120", "Bb", 1, lpf: 70, amp: 2
+```
+
+## Sources
+
+The sample filter pre-arg system understands two types of information:
+sources and filters. Sources are information used to create the list of
+potential candidates. A source can take two forms:
+
+1. "/path/to/samples" - a string representing a valid path to a directory 
+2. "/path/to/samples/foo.wav" - a string representing a valid path to a sample
+
+The `sample` fn will first gather all sources and use them to create a
+large list of candidates. This list is constructed by first adding all
+valid paths and then by adding all the valid `.flac`, `.aif`, `.aiff`,
+`.wav`, `.wave` files contained within the directories.
+
+For example, take a look at the following code:
+
+```
+samps = "/path/to/my/samples/"
+samps2 = "/path/to/my/samples2/"
+path = "/path/to/my/samples3/foo.wav"
+
+sample samps, samps2, path, 0
+```
+
+Here, we're combining the contents of the samples within two directories
+and adding a specific sample. If `"/path/to/my/samples/"` contained 3
+samples and `"/path/to/my/samples2/"` contained 12, we'd have 16
+potential samples to index and filter (3 + 12 + 1).
+
+By default, only the sample files within a directory are gathered into
+the candidate list. Sometimes you might have number of nested folders of
+samples you wish to search and filter within. You can therefore do a
+recursive search for all samples within all subfolders of a particular
+folder by adding `**` to the end of the path:
+
+```
+samps = "/path/to/nested/samples/**"
+sample samps, 0
+```
+
+Take care though as searching through a very large set of folders may
+take a long time. However, the contents of all folder sources are
+cached, so the delay will only happen the first time.
+
+
+## Filters
+
+Once you have a list of candidates you may use the following filtering
+types to further reduce the selection:
+
+* `"foo"` Strings will filter on substring occurrance within file name (minus directory path and extension).
+* `/fo[oO]/` Regular Expressions will filter on pattern matching of file name (minus directory path and extension).
+* `:foo` - Keywords will filter candidates on whether the keyword is a direct match of the filename (minus directory path and extension).
+* `lambda{ "foo" }` - Procs with no arguments will be automatically called and their result be treated as a source or filter.
+* `lambda{|a| ... }` - Procs with one argument will be treated as a candidate filter or genrator function. It will be passed the list of current candidates and must return a new list of candidates (a list of valid paths to sample files).
+* `1` - Numbers will select the candidate with that index (wrapping round like a ring if necessary).
+
+## Composites
+
+Finally, you may use lists wherever you may place a source or
+filter. The list will be automatically flattened and the contents be
+treated as regular sources and filters. Therefore the following calls to
+`sample` are semantically equivalent:
+
+```
+sample "/path/to/dir", "100", "C#"
+sample ["/path/to/dir", "100", "C#"]
+sample "/path/to/dir", ["100", "C#"]
+sample ["/path/to/dir", ["100", ["C#"]]]
+```
+
+## Wrapping Up
+
+This was an advanced section for people that need real power to
+manipulate and use sample packs. If most of this section didn't make too
+much sense, don't worry. It's likely you don't need any of this
+functionality just yet. However, you'll know when you do need it and you
+can come back and re-read this when you start working with large
+directories of samples.

+8.5 Łańcuchy Pierścieni (Ring Chains)
+
+Oprócz konstruktorów takich jak `range` i `spread` innym sposobem 
+tworzenia nowych pierścieni jest manipulowanie i modyfikacja istniejących 
+pierścieni (rings).
+
+## Łańcuchy poleceń (Chain Commands)
+
+Aby zbadać ten temat stwórzmy prosty pierścień: 
+
+```
+(ring 10, 20, 30, 40, 50)
+```
+
+Co jeśli chcielibyśmy otrzymać wszystkie elementy tego pierścienia 
+w odwrotnej kolejności? Wystarczy, że użyjemy w łańuchu poleceń 
+`.reverse` aby wziąć nasz pierścień i odwrócić go:
+
+```
+(ring 10, 20, 30, 40, 50).reverse  #=> (ring 50, 40, 30, 20, 10)
+```
+
+A co, jeśli teraz potrzebujemy tylko pierwsze trzy elementy 
+z naszego pierścienia?
+
+```
+(ring 10, 20, 30, 40, 50).take(3)  #=> (ring 10, 20, 30)
+```
+
+I na koniec jeszcze jedno, co jeśli chcielibyśmy przetasować 
+elementy naszego pierścienia tak jak tasujemy karty przed grą?
+
+```
+(ring 10, 20, 30, 40, 50).shuffle  #=> (ring 40, 30, 10, 50, 20)
+```
+
+## Wiele Łańcuchów
+
+Powyższe polecenia dają bardzo duże możliwości tworzenia nowych pierścieni (rings). 
+Jednakże, *prawdziwa* moc pojawia się dopiero w momencie, gdy połączysz kilka 
+poleceni w jeden łańcuch.
+
+Co powiesz na to aby najpierw przetasować pierścień, potem usunać z niego 
+1 element i z elementów, które pozostały wybrać tylko pierwsze 3?
+
+Zróbmy to krok po kroku: 
+
+1. `(ring 10, 20, 30, 40, 50)` - nasz początkowy pierścień
+2. `(ring 10, 20, 30, 40, 50).shuffle` - tasujemy - `(ring 40, 30, 10, 50, 20)`
+3. `(ring 10, 20, 30, 40, 50).shuffle.drop(1)` - usuwamy 1-wszy element - `(ring 30, 10, 50, 20)`
+4. `(ring 10, 20, 30, 40, 50).shuffle.drop(1).take(3)` - pozostawiamy tylko pierwsze 3 - `(ring 30, 10, 50)`
+
+Widzisz jak łatwo możemy stworzyć długi łańcuch tych metod  *sklejając 
+je po prostu razem*? Możemy użyć tych metod w dowolnej kolejności 
+na jaką nas tylko najdzie ochota. Dzięki temu mamy bardzo bogatą 
+i potężną paletę sposobów, dzięki którym możemy tworzyć nowe pierścienie 
+z już istniejących.
+
+## Niezmienność
+
+Pierścienie posiadają pewną potężną i ważną cechę. Są niezmienne co 
+oznacza, że gdy raz zostaną już utworzone to nie mogą zostać zmienione. 
+Z tego wynika, że łańcuchy wywołań metod opisane w tym rozdziale 
+*nie zmieniają pierścieni* lecz *tworzą nowe pierścienie*. Dzięki takiemu 
+podejśćiu nic nie stoi na przeszkodzie abyś mógł współdzielić dany 
+pierścień pomiędzy różnymi wątkami i wywyływać na nim łańcuchy metod 
+w ramach jednego wątku, gdyż wiesz że nie wpłynie to w żaden sposób 
+na jakikolwiek inny wątek, który korzysta z tego samego pierścienia.
+
+## Dostępne Łańcuchy Metod
+
+Oto lista metod, które możesz łączyć w łańcuchy wywołań:
+
+* `.reverse` - zwraca odwróconą wersję pierścienia
+* `.sort`    - tworzy posortowaną wersję pierścienia
+* `.shuffle` - tworzy pierścień z wartościami, które są przetasowane
+* `.pick(3)` - zwraca pierścień, który zawiera 3 losowo wybrane elementy z oryginalnego pierścienia (działanie analogiczne do funkcji `choose`)
+* `.pick`    - działanie analogiczne do funkcji `.pick(3)`, z tym że w tym przypadku liczba wylosowanych elementów jest równa ilości elementów znajdujących się w oryginalnym pierścieniu  
+* `.take(5)` - zwraca nowy pierścień, który zawiera tylko 5 pierwszych elementów
+* `.drop(3)` - zwraca nowy pierścień, który zawiera wszystkie elementy oprócz pierwszych 3

+A.6 Musical Minecraft 
+
+# Musical Minecraft
+
+
+
+Hello and welcome back! In the previous tutorials we've focussed purely
+on the music possibilities of Sonic Pi - (turning your Raspberry Pi into
+a performance ready musical instrument). So far we've learned how to:
+
+* Live Code - changing the sounds on-the-fly,
+* Code some huge beats,
+* Generate powerful synth leads,
+* Re-create the famous TB-303 acid-bass sound.
+
+There's so much more to show you (which we will explore in future
+editions). However, this month, let's look at something Sonic Pi can do
+that you probably didn't realise: control Minecraft.
+
+# Hello Minecraft World
+
+OK, let's get started. Boot up your Raspberry Pi, fire up Minecraft Pi
+and create a new world. Now start up Sonic Pi and re-size and move your
+windows so you can see both Sonic Pi and Minecraft Pi at the same time.
+
+In a fresh buffer type the following:
+
+    mc_message "Hello Minecraft from Sonic Pi!"
+    
+Now, hit Run. Boom! Your message appeared in Minecraft! How easy was
+that? Now, stop reading this for a moment and play about with your own
+messages. Have fun!
+
+![Screen 0](../images/tutorial/articles/A.06-minecraft/Musical-Minecraft-0-small.png)
+
+# Sonic Teleporter
+
+Now let's do some exploring. The standard option is to reach for the
+mouse and keyboard and start walking around. That works, but it's pretty
+slow and boring. It would be far better if we had some sort of teleport
+machine. Well, thanks to Sonic Pi, we have one. Try this:
+
+    mc_teleport 80, 40, 100
+    
+Crikey! That was a long way up. If you weren't in flying-mode then you
+would have fallen back down all the way to the ground. If you double-tap
+space to enter flying-mode and teleport again, you'll stay hovering at
+the location you zap to.
+
+Now, what do those numbers mean? We have three numbers which describe
+the coordinates of where in the world we want to go. We give each number
+a name - x, y and z:
+
+* x - how far left and right (80 in our example)
+* y - how high we want to be (40 in our example)
+* z - how far forward and back (100 in our example)
+
+By choosing different values for x, y and z we can teleport *anywhere*
+in our world. Try it! Choose different numbers and see where you can end
+up. If the screen goes black it's because you've teleported yourself
+under the ground or into a mountain. Just choose a higher y value to get
+back out above land. Keep on exploring until you find somewhere you
+like...
+
+Using the ideas so far, let's build a Sonic Teleporter which makes a fun
+teleport sound whilst it whizzes us across the Minecraft world:
+
+    mc_message "Preparing to teleport...."
+    sample :ambi_lunar_land, rate: -1
+    sleep 1
+    mc_message "3"
+    sleep 1
+    mc_message "2"
+    sleep 1
+    mc_message "1"
+    sleep 1
+    mc_teleport 90, 20, 10
+    mc_message "Whoooosh!"
+    
+![Screen 1](../images/tutorial/articles/A.06-minecraft/Musical-Minecraft-1-small.png)
+
+# Magic Blocks
+
+Now you've found a nice spot, let's start building. You could do what
+you're used to and start clicking the mouse furiously to place blocks
+under the cursor. Or you could use the magic of Sonic Pi. Try this:
+
+    x, y, z = mc_location
+    mc_set_block :melon, x, y + 5, z
+
+Now look up! There's a melon in the sky! Take a moment to look at the
+code. What did we do? On line one we grabbed the current location of
+Steve as the variables x, y and z. These correspond to our coordinates
+described above. We use these coordinates in the fn `mc_set_block` which
+will place the block of your choosing at the specified coordinates. In
+order to make something higher up in the sky we just need to increase
+the y value which is why we add 5 to it. Let's make a long trail of them:
+
+    live_loop :melon_trail do
+      x, y, z = mc_location
+      mc_set_block :melon, x, y-1, z
+      sleep 0.125
+    end
+
+Now, jump over to Minecraft, make sure you're in flying-mode (double tap
+space if not) and fly all around the world. Look behind you to see a
+pretty trail of melon blocks! See what kind of twisty patterns you can
+make in the sky.
+
+# Live Coding Minecraft
+
+Those of you that have been following this tutorial over the last few
+months will probably have your minds blown at this point. The trail of
+melons is pretty cool, but the most exciting part of the previous
+example is that you can use `live_loop` with Minecraft! For those that
+don't know, `live_loop` is Sonic Pi's special magic ability that no
+other programming language has. It lets you run multiple loops at the
+same time and allows you to change them whilst they run. They are
+incredibly powerful and amazing fun. I use `live_loop`s to perform music
+in nightclubs with Sonic Pi - DJs use discs and I use `live_loop`s :-)
+However, today we're going to live code both music and Minecraft.
+
+Let's get started. Run the code above and start making your melon
+trail again. Now, without stopping the code, just simply change `:melon` to
+`:brick` and hit run. Hey presto, you're now making a brick trail. How
+simple was that! Fancy some music to go with it? Easy. Try this:
+
+    live_loop :bass_trail do
+      tick
+      x, y, z = mc_location
+      b = (ring :melon, :brick, :glass).look
+      mc_set_block b, x, y -1, z
+      note = (ring :e1, :e2, :e3).look
+      use_synth :tb303
+      play note, release: 0.1, cutoff: 70
+      sleep 0.125
+    end
+    
+Now, whilst that's playing start changing the code. Change the block
+types - try `:water`, `:grass` or your favourite block type. Also, try
+changing the cutoff value from `70` to `80` and then up to `100`. Isn't
+this fun?
+
+# Bringing it all together
+
+![Screen 2](../images/tutorial/articles/A.06-minecraft/Musical-Minecraft-2-small.png)
+
+Let's combine everything we've seen so far with a little extra
+magic. Let's combine our teleportation ability with block placing and
+music to make a Minecraft Music Video. Don't worry if you don't
+understand it all, just type it in and have a play by changing some of
+the values whilst it's running live. Have fun and see you next time...
+    
+
+    live_loop :note_blocks do
+      mc_message "This is Sonic Minecraft"
+      with_fx :reverb do
+        with_fx :echo, phase: 0.125, reps: 32 do
+          tick
+          x = (range 30, 90, step: 0.1).look
+          y = 20
+          z = -10
+          mc_teleport x, y, z
+          ns = (scale :e3, :minor_pentatonic)
+          n = ns.shuffle.choose
+          bs = (knit :glass, 3, :sand, 1)
+          b = bs.look
+          synth :beep, note: n, release: 0.1
+          mc_set_block b, x+20, n-60+y, z+10
+          mc_set_block b, x+20, n-60+y, z-10
+          sleep 0.25
+        end
+      end
+    end
+    
+    live_loop :beats do
+      sample :bd_haus, cutoff: 100
+      sleep 0.5

+A.9 Randomisation
+
+# Surfing Random Streams
+
+Back in episode 4 of this tutorial series we took a brief look at
+randomisation whilst coding up some sizzling synth riffs. Given that
+randomisation is such an important part of my live coding DJ sets I
+thought it would be useful to cover the fundamentals in much greater
+detail. So, get your lucky hat on and let's surf some random streams!
+
+# There is no random
+
+The first thing to learn which might really surprise you when playing
+with Sonic Pi's randomisation functions is that they're not actually
+really random. What does this actually mean? Well, let's try a couple of
+tests. First, imagine a number in your head between 0 and 1. Keep it
+there and don't tell me. Now let me guess... was it `0.321567`? No? Bah,
+I'm clearly no good at this. Let me have another go, but let's ask Sonic
+Pi to choose a number this time. Fire up Sonic Pi v2.7+ and ask it for a
+random number but again don't tell me:
+
+    print rand
+    
+Now for the reveal... was it `0.75006103515625`? Yes! Ha, I can see
+you're a little sceptical. Perhaps it was just a lucky guess. Let's try
+again. Press the Run button again and see what we get... What?
+`0.75006103515625` again? This clearly can't be random! You're right,
+it's not.
+
+What's going on here? The fancy computer science word here is
+determinism. This just means that nothing is by chance and everything is
+destined to be. Your version of Sonic Pi is destined to always return
+`0.75006103515625` in the program above. This might sound pretty
+useless, but let me assure you that it's one of the most powerful parts
+of Sonic Pi. If you stick at it you'll learn how to rely on the
+deterministic nature of Sonic Pi's randomisation as a fundamental
+building block to your compositions and live coded DJ sets.
+
+# A Random Melody
+
+When Sonic Pi boots it actually loads into memory a sequence of 441,000
+pre-generated random values. When you call a random function such as
+`rand` or `rrand`, this random stream is used to generate your
+result. Each call to a random function consumes a value from this
+stream. Therefore the 10th call to a random function will use the 10th
+value from the stream. Also, every time you press the Run button, the
+stream is reset for that run. This is why I could predict the result to
+`rand` and why the 'random' melody was the same every time. Everybody's
+version of Sonic Pi uses the exact same random stream which is very
+important when we start sharing our pieces with each other. 
+
+Let's use this knowledge to generate a repeatable random melody:
+
+    8.times do
+     play rrand_i(50, 95)
+     sleep 0.125
+    end
+
+Type this into a spare buffer and hit Run. You'll hear a melody
+consisting of 'random' notes between 50 and 95. When it's finished, hit
+Run again to hear exactly the same melody again.
+
+*start breakout box*
+## Handy Randomisation Functions
+ Sonic Pi comes with a number of useful functions for working with the
+random stream. Here's a list of some of the most useful:
+
+* `rand` - Simply returns the next value in the random stream
+* `rrand` - Returns a random value within a range
+* `rrand_i` - Returns a random whole number within a range
+* `one_in` - Returns true or false with the given probability
+* `dice` - Imitates rolling a dice and returns a value between 1 and 6
+* `choose` - Chooses a random value from a list
+
+Check out their documentation in the Help system for detailed
+information and examples.
+
+ *end breakout box*
+
+# Resetting the Stream
+
+Whilst the ability to repeat a sequence of chosen notes is essential to
+allow you to replay a riff on the dance floor, it might not be the
+exactly riff you want. Wouldn't it be great if we could try a number of
+different riffs and choose the one we liked best? This is where the real
+magic starts.
+
+We can manually set the stream with the fn `use_random_seed`. In
+Computer Science, a random seed is the starting point from which a new
+stream of random values can sprout out and blossom. Let's try it:
+
+    use_random_seed 0
+    3.times do
+      play rrand_i(50, 95)
+      sleep 0.125
+    end
+    
+Great, we get the first three notes of our random melody above: `84`,
+`83` and `71`. However, we can now change the seed to something
+else. How about this:
+
+    use_random_seed 1
+    3.times do
+      play rrand_i(50, 95)
+      sleep 0.125
+    end
+    
+    
+Interesting, we get `83`, `71` and `61` . You might notice that the
+first two numbers here are the same as the last two numbers before -
+this isn't a coincidence.
+
+Remember that the random stream is just a giant list of 'pre-rolled'
+values. Using a random seed simply jumps us to a point in that
+list. Another way of thinking about it is to imagine a huge deck of
+pre-shuffled cards. Using a random seed is cutting the deck at a
+particular point. The fabulous part of this is that it's precisely this
+ability to jump around the random which gives us huge power when making
+music.
+
+Let's revisit our random melody of 8 notes with this new stream
+resetting power, but let's also throw in a live loop so we can
+experiment live whilst it's playing:
+
+    live_loop :random_riff do    
+      use_random_seed 0
+      8.times do
+        play rrand_i(50, 95), release: 0.1
+        sleep 0.125
+      end
+    end
+
+Now, whilst it's still playing, change the seed value from `0` to
+something else. Try `100`, what about `999`. Try your own values,
+experiment and play around - see which seed generates the riff you like
+best.
+
+# Bringing it all together
+
+This month's tutorial has been quite a technical dive into the workings
+of Sonic Pi's randomisation functionality. Hopefully it has given you
+some insight into how it works and how you can start using randomisation
+in a reliable way to create repeatable patterns within your music. It's
+important to stress that you can use repeatable randomisation *anywhere*
+you want. For example, you can randomise the amplitude of notes, the
+timing of the rhythm, the amount of reverb, the current synth, the mix
+of an FX, etc. etc. In the future we'll take a close look at some of
+these applications, but for now let me leave you with a short example.
+
+Type the following into a spare buffer, hit Run, and then start changing
+the seeds around, hit Run again (whilst it's still playing) and explore
+the different sounds, rhythms and melodies you can make. When you find a
+nice one, remember the seed number so you can get back to it. Finally,
+when you've found a few seeds you like, put on a live coded performance
+for your friends by simply switching between your favourite seeds to
+create a full piece.
+
+live_loop :random_riff do
+  use_random_seed 10300
+  use_synth :prophet
+  s = [0.125, 0.25, 0.5].choose
+  8.times do
+    r = [0.125, 0.25, 1, 2].choose
+    n = (scale :e3, :minor).choose
+    co = rrand(30, 100)
+    play n, release: r, cutoff: co
+    sleep s
+  end
+end
+
+live_loop :drums do
+  use_random_seed 2001
+  16.times do
+    r = rrand(0.5, 10)
+    sample :drum_bass_hard, rate: r, amp: rand
+    sleep 0.125

+A.10 Control
+
+# Controlling Your Sound
+
+So far during this series we've focussed on triggering sounds. We've
+discovered that we can trigger the many synths built into Sonic Pi with
+`play` or `synth` and how to trigger pre-recorded samples with
+`sample`. We've also looked at how we can wrap these triggered sounds
+within studio FX such as reverb and distortion using the `with_fx`
+command. Combine this with Sonic Pi's incredibly accurate timing system
+and you can produce a vast array of sounds, beats and riffs. However,
+once you've carefully selected a particular sound's options and
+triggered it, there's no ability to mess with it whilst it's playing
+right? Wrong! Today you're going to learn something very powerful - how
+to control running synths.
+
+## A Basic Sound
+
+Let's create a nice simple sound. Fire up Sonic Pi and in a fresh buffer
+type the following:
+
+```
+synth :prophet, note: :e1, release: 8, cutoff: 100
+```
+
+Now press the Run button at the top left to hear a lovely rumbling synth
+sound. Go ahead, press it again a few times to get a feel for it. OK,
+done? Let's start controlling it!
+
+
+## Synth Nodes
+
+A little known feature in Sonic Pi is that the fns `play`, `synth` and
+`sample`, return something called a `SynthNode` which represents a
+running sound. You can capture one of these `SynthNode`s using a
+standard variable and then **control** it at a later point in time. For
+example, let's change the value of the `cutoff:` opt after 1 beat:
+
+```
+sn = synth :prophet, note: :e1, release: 8, cutoff: 100
+sleep 1
+control sn, cutoff: 130
+```
+
+Let's look at each line in turn: 
+
+Firstly we trigger the `:prophet` synth using the `synth` fn as
+norml. However we also capture the result in a variable called `sn`. We
+could have called this variable something completely different such as
+`synth_node` or `jane` - the name doesn't matter. However, it's
+important to choose a name that's meaningful to you for your
+performances and for people reading your code. I chose `sn` as it's a nice
+short mnemonic for synth node.
+
+On line 2 we have a standard `sleep` command. This does nothing special
+- it just asks the computer to wait for 1 beat before moving onto the
+next line.
+
+Line 3 is where the control fun starts. Here, we use the `control` fn to
+tell our running `SynthNode` to change the cutoff value to `130`. If you
+hit the **Run** button, you'll hear the `:prophet` synth start playing
+as before, but after 1 beat it will shift to sound a lot brighter.
+
+
+** Breakout Box Start **
+Modulatable Options
+
+Most of Sonic Pi's synths and FX opts may be changed after being
+triggered. However, this isn't the case for all of them. For example,
+the envelope opts `attack:`, `decay:`, `sustain:` and `release:` can
+only be set when triggering the synth. Figuring out which opts can and
+can't be changed is simple - just head to the documentation for a given
+synth or FX and then scroll down to the individual option documentation
+and look for the phrases "May be changed whilst playing " or "Can not be
+changed once set". For example, the documentation for the `:beep`
+synth's `attack:` opt makes it clear that it's not possible to change
+it:
+
+* Default: 0 
+* Must be zero or greater

+
+## Multiple Changes
+
+Whilst a synth is running you're not limited to changing it only once -
+you're free to change it as many times as you like. For example, we can
+turn our `:prophet` into a mini arpegiator with the following:
+
+```
+notes = (scale :e3, :minor_pentatonic)
+sn = synth :prophet, note: :e1, release: 8, cutoff: 100
+sleep 1
+16.times do
+  control sn, note: notes.tick
+  sleep 0.125
+end
+```
+
+In this snippet of code we just added a couple of extra things. First we
+defined a new variable called `notes` which contains the notes we'd like
+to cycle through (an arpeggiator is just a fancy name for something that
+cycles through a list of notes in order). Secondly we replaced our
+single call to `control` with an iteration calling it 16 times. In each
+call to `control` we `.tick` through our ring of `notes` which will
+automaticall repeat once we get to the end (thanks to the fabulous power
+of Sonic Pi's rings). For a bit of variety try replacing `.tick` with
+`.choose` and see if you can hear the difference.
+
+Note that we can change multiple opts simultaneously. Try changing the
+control line to the following and listen for the difference:
+
+```
+control sn, note: notes.tick, cutoff: rrand(70, 130)
+```
+
+## Sliding 
+
+When we control a `SynthNode`, it responds exactly on time and instantly
+changes the value of the opt to the new one as if you'd pressed a button
+or flicked a switch requesting the change. This can sound rhythmical and percussive -
+especially if the opt controls an aspect of the timbre such as
+`cutoff:`. However, sometimes you don't want the change to happen
+instantaneously. Instead, you might want to smoothly move from the
+current value to the new one as if you'd moved a slider or dial. Of
+course, Sonic Pi can also do this too using the `_slide:` opts.
+
+Each opt that can be modified also has a special corresonding `_slide:`
+opt that allows you to specify a slide time. For example, `amp:` has
+`amp_slide:` and `cutoff:` has `cutoff_slide:`. These slide opts work
+slightly differently than all the other opts in that they tell the synth
+note how to behave **next time they are controlled**. Let's take a look:
+
+```
+sn = synth :prophet, note: :e1, release: 8, cutoff: 70, cutoff_slide: 2
+sleep 1
+control sn, cutoff: 130
+```
+
+Notice how this example is exactly the same as before except with the
+addition of `cutoff_slide:`. This is saying that next time this synth
+has its `cutoff:` opt controlled, it will take 2 beats to slide from the
+current value to the new one. Therefore, when we use `control` you can
+hear the cutoff slide from 70 to 130. It creates an interesting dynamic
+feel to the sound. Now, try changing the `cutoff_slide:` time to a
+shorter value such as 0.5 or a longer value such as 4 to see how it
+changes the sound. Remember, you can slide any of the modifiable opts in
+exactly this way and each `_slide:` value can be totally different so
+you can have the cutoff sliding slowly, the amp sliding fast and the pan
+sliding somewhere in between if that's what you're looking to create...
+
+
+## Bringing it all together
+
+Let's look at a short example which demonstrates the power of
+controlling synths after they've been triggered. Notice that you can
+also slide FX just like synths although with a slightly different
+syntax. Check out section 7.2 of the built-in tutorial for more
+information on controlling FX.
+
+Copy the code into a spare buffer and take a listen. Don't stop there
+though - play around with the code. Change the slide times, change the
+notes, the synth, the FX and the sleep times and see if you can turn it
+into something completely different!
+
+
+```
+live_loop :moon_rise do
+  with_fx :echo, mix: 0, mix_slide: 8 do |fx|
+    control fx, mix: 1
+    notes = (scale :e3, :minor_pentatonic, num_octaves: 2).shuffle
+    sn = synth :prophet , sustain: 8, note: :e1, cutoff: 70, cutoff_slide: 8
+    control sn, cutoff: 130
+    sleep 2
+    32.times do
+      control sn, note: notes.tick, pan: rrand(-1, 1)
+      sleep 0.125
+    end
+  end
+end

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Waveforms (AKWF)
+
+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2
+
+You find them on-line at:

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Waveforms (AKWF)
+
+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2
+
+You find them on-line at:

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Waveforms (AKWF)
+
+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2
+
+You find them on-line at:

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Waveforms (AKWF)
+
+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Waveforms (AKWF)
+
+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2
+
+You find them on-line at:

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting

+Adventure Kid Waveforms (AKWF)
+
+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2
+
+You find them on-line at:

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Waveforms (AKWF)
+
+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2
+
+You find them on-line at:

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Waveforms (AKWF)
+
+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens

+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+
+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Waveforms (AKWF)
+
+AKWF is a collection of one cycle waveforms sampled
+from various sources intended for use as oscillator
+shapes in samplers and synthesizers.
+
+Length = 600 samples
+Pitch = D1+2

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.

+Adventure Kid Research & Technology (AKRT)
+
+While making music I have always try what happens
+if I miss use something and try to find things
+through experimenting - I love both old technology
+and new. Through the years I have sampled a lot of
+stuff, programmed my own synthesizers and effects 
+and tried a lot of techniques. Adventure Kid
+Research & Technology is my way of both collecting
+and sharing what I make and find.
