Clanlib is a multi-platform software development kit, with an emphasis on game development.

on one side, it tries to provide a platform independent interface to write games with, by taking over the low-level work from the game and providing wrappers around toolkits such as directfb, directx, opengl, vorbis, x11, etc., so that if a game is written with clanlib, the game should compile on any platform supported by clanlib without changing its source code.

on the other hand, clanlib also tries to be a service-minded sdk. in other words, the developers have put great effort into designing the api, to ensure clanlib's ease of use - while maintaining its power.

this is the development part of the clanlib sdk, which is needed to build applications with it.
