PSSMCameraRig usage example?

I’m looking at implementing cascading shadow map, but since Panda includes some of the code from RenderPipeline, I will give PSSMCameraRig a try before implementing my own solution.

But before I dive into the code, is it usable outside RenderPipeline ? Also, are there any examples on how to use it or some high level documentation (apart from the API doc) ?
