+Building on Windows (experimental)
+
+Python setup:
+1. Install Python 2.5
+2. Go into c:\Python25\Lib\distutils and create distutils.cfg containing:
+[build]
+compiler=mingw32
+
+MinGW setup:
+1. Download and install MinGW to C:\MinGW
+2. Download "pexports" (google for it) utility and put in c:\MinGW\bin
+3. Add C:\MinGW\bin to Windows PATH
+
+HDF5 setup:
+You MUST use the versions build with VS2005!
+
+1. Download pre-build HDF5 1.8.1 (with DLLS) compiled with VS2005:
+ftp://ftp.hdfgroup.org/HDF5/current/bin/windows/5-181-win-vs2005.zip
+2. Download SZIP
+ftp://ftp.hdfgroup.org/lib-external/szip/2.1/bin/windows/szip21-vs2005-enc.zip
+3. Download ZLIB
+ftp://ftp.hdfgroup.org/lib-external/zlib/1.2/bin/windows/zlib123-vs2005.zip
+
+4. Unzip HDF5 to "C:\h181"  You should now have C:\h181\include, etc.
+5. Open SZIP and ZLIB archives and copy their dlls to "C:\h181\dll"
+
+6. Download and install "Microsoft Visual C++ 2005 SP1 Redistributable Package"
+   It must be EXACTLY this, note it's **SP1**, or the HDF5 dll won't load.
+   This is available from Microsoft's web site.
+   
+Create import library
+1. Open a terminal and cd to C:\h181\lib
+2. Run "pexports hdf5dll.dll > hdf5dll.def" to get the list of HDF5 exports
+3. Run "dlltool -D hdf5dll.dll -d hdf5dll.def -l hdf5dll.dll.a" to create
+   an import library that MinGW can handle.
+3. Create the directory C:\h181\dll2
+4. Copy the new file c:\h181\dll\hdf5dll.dll.a into c:\h181\dll2
+5. Add the directory c:\h181\dll (NOT c:\h181\dll2) to your Windows PATH
+
+Compile h5py
+1. Extract h5py to c:\h5py
+2. Run python setup.py build --hdf5=c:\h181
+3. Run python setup.py test --hdf5=c:\h181
+
+Isn't Windows easy to use?
