An interface for emulator and game ports

For each emulator 'core', RetroArch makes use of a library API that we like to call 'libretro'. Think of libretro as an interface for emulator and game ports. You can make a libretro port once and expect the same code to run on all the platforms that RetroArch supports. It's designed with simplicity and ease of use in mind so that the porter can worry about the port at hand instead of having to wrestle with an obfuscatory API. The purpose of the project is to help ease the work of the emulator/game porter by giving him an API that allows him to target multiple platforms at once without having to redo any code. He doesn't have to worry about writing input/video/audio drivers - all of that is supplied to him by RetroArch. All he has to do is to have the emulator port hook into the libretro API and that's it - we take care of the rest.
