+Library: libwmapro
+Imported: 2010-04-30 by Mohamed Tarek
+
+This set of files form the files needed from ffmpeg's libavcodec and libavutil
+to build a standalone wma professional decoder.
+
+LICENSING INFORMATION
+
+ffmpeg is licensed under the Lesser GNU General Public License and the file
+wmaprodec.c is copyright (c) 2007 Baptiste Coudurier, Benjamin Larsson, Ulion
+and copyright (c) 2008 - 2009 Sascha Sommer, Benjamin Larsson.
+
+IMPORT DETAILS
+
+Based on ffmpeg svn r228866 dated 15 April 2010.
+
+Currently, the files contain minimal changes from their original state in order
+to be able to compile cleanly. 
+
+The file wmaprodec.c contains a main function that is just a stub to make sure 
+linking is done properly and without errors.
+
+COMPILING
+
+A make file is included that would compile and link the files when the "make"
+command is executed without arguments in any Unix-like environment.
+
+The file porduces an output binary called "test" that, as of now (30 April 2010)
+, is still useless. 
+
+To clean the compiler output and retain just the source code, the following 
+command should be executed:
+make clean
