+ *  Remember to add these frameworks: GLUT, OpenAL, OpenGL
+ *  Otherwise, Undefined symbols: errors will result
+ *
+ *  Several prebind errors will occur, but I was still able to compile
+ *  and run the program.
+ *
+ *  A VERY important step to get this to work is to copy the .wav files into
+ *  the <app name>.app/Contents/MacOS folder.  You need to use Terminal to do
+ *  this since the Finder windows interpret the <app name>.app as an executable
+ *  file instead.
