 * INTRODUCTION
 * Fmod is an API (Application Programming Interface) that allow you to use music
 * and creating sound effects with a lot of sort of musics.
 * Fmod is at :
 * 		http://www.fmod.org/
 * The reason of this project is that Fmod can't be used in Java direcly, so I've created
 * NativeFmod project.
