ASSIMP - Skeletal Animation Library

Today, I come across a Skeletal Animation library which is called ASSIMP.

http://assimp.sourceforge.net/lib_html/index.html

It looks pretty powerful, it can import a lot of file format such as COLLADA, 3DS, .X..etc.
It has no rendering part, so it is quite flexible and can be integrated to your game engine.
I am now studying how to use it so that my game engine can have skeletal animation feature.
