+# Locates the SDL_sound library
+
+# This module depends on SDL being found and 
+# must be called AFTER FindSDL.cmake is called.
+
+# This module defines
+# SDL_SOUND_INCLUDE_DIR, where to find SDL_sound.h
+# SDL_SOUND_FOUND, if false, do not try to link to SDL
+# SDL_SOUND_LIBRARIES, this contains the list of libraries that you need to link against
+#
+# This module also defines (but you shouldn't need to use directly)
+# SDL_SOUND_LIBRARY, the name of just the SDL_sound library you would link against.
+# And might define the following as needed
+# MIKMOD_LIBRARY
+# MODPLUG_LIBRARY
+# OGG_LIBRARY
+# VORBIS_LIBRARY
+# SMPEG_LIBRARY
+# FLAC_LIBRARY
+# SPEEX_LIBRARY
+#
+# Typically, you should not use these variables directly, and you should use 
+# SDL_SOUND_LIBRARIES which contains SDL_SOUND_LIBRARY and the other audio libraries 
+# (if needed) to successfully compile on your system . 
+#
+# Created by Eric Wing. 
+# This module is a bit more complicated than the other FindSDL* family modules.
+# The reason is that SDL_sound can be compiled in a large variety of different ways
+# which are independent of platform. SDL_sound may dynamically link against other 3rd
+# party libraries to get additional codec support, such as Ogg Vorbis, SMPEG, ModPlug,
+# MikMod, FLAC, Speex, and potentially others. Some platforms or compilers seem to 
+# require that dependent libraries of libraries you use must also be explicitly 
+# linked against in order to successfully compile. SDL_sound does not currently 
+# have any system in place to know how it was compiled.
+# So this CMake module does the hard work in trying to discover which 3rd party 
+# libraries are required for building.
+# This module uses a brute force approach to create a test program that uses SDL_sound,
+# and then tries to build it. If the build fails, it parses the error output for 
+# known symbol names to figure out which libraries are needed.
+#
+# Responds to the $SDLDIR and $SDLSOUNDDIR environmental variable that would
+# correspond to the ./configure --prefix=$SDLDIR used in building SDL.
+#
+# On OSX, this will prefer the Framework version (if found) over others.
+# People will have to manually change the cache values of 
+# SDL_LIBRARY to override this selection.
