* Canary is not killed when Asterisk is stopped.
* Some man pages to write.
-* Remove the TeX sources from the package asterisk-doc .
-* Package sound files properly. Maybe in a separate package altogether?
- See also patch make-clean-fixes.
+* Is it OK to ship AST.{pdf,txt}?
+* Get rid of the lump of code in patch mpglib. Rewrite using code from mpg123?

+Description: mpglib code originally in asterisk-addons
+Origin: http://svn.digium.com/svn/thirdparty/mp3/trunk
+
+The package asterisk-addons originally included mpglib. After the merge
+with asterisk, that code is no longer included and needs to be fetched
+(contrib/scripts/get_mpg_source.sh). This patch includes that fetched
+source (rev. 180).

++MP3 library
++-----------
++Version 0.2
++
++This decoder is a 'light' version (thrown out all unnecessay parts)
++from the mpg123 package. I made this for a company.
++
++Currently only Layer3 is enabled to save some space. Layer1,2 isn't
++tested at all. The interface will not change significantly.
++A backport to the mpg123 package is planed.
++
++comiled and tested only on Solaris 2.6
++main.c contains a simple demo application for library.
++
++COPYING: you may use this source under GPL terms!
++
++PLEASE NOTE: This software may contain patented alogrithm (at least
++ patented in some countries). It may be not allowed to sell/use products
++ based on this source code in these countries. Check this out first!
++
++COPYRIGHT of MP3 music:
++ Please note, that the duplicating of copyrighted music without explicit
++ permission violates the rights of the owner.
++
++SENDING PATCHES:
++ Maybe I change the copyright policy (ie some kind of more free BSD licencse).
++ Please consider this when sending patches/changes.
++ I also want to have the freedom to sell the code to companies that
++ can not use the code under GPL. So, if you send me significant patches,
++ I need your explicit permission to do this. Of course, there will also
++ be the GPLed open source version of the 100% same code.
++ For the case you cannot accept this: the code is GPL, it's your freedom
++ to distribute your changes again under GPL.
++
++FEEDBACK:
++ I'm interessted to here from you, when you use this package as part
++ of another project.
