I'm working on Animadead right now. The next release should be faily soon I hope. And there are 12 tutorial demos in the next version that walk you through using the library from the simplest features to the most comlpex. The next version even comes with example shaders you can use.
The biggest problem with Animadead so far has been lack of support for other modeling packages, so what I'm working on right now is an Animadead Format Writer library. It has API calls to specify the data in a generic way, and then compiles the data and writes it in the Animadead format.
I'll be including an exporter for 3DS MAX as well in the next release, and hopefully with this new library it will be much easier for people to make contributions with exporters for other packages.
As for right now though, the best way to learn Animadead is to look at the example programs, and take a look at the class hierarchy online.
There's contact info on the page, and if you have any questions using Animadead, I'll be happy to help.
