Where is the documentation for TGEA?

I've been looking for this ever since I downloaded torque. I'm hoping someone can help me so I can stop asking questions for every little thing I try to do. For example, right now I'm trying to make the camera orbit. I tried the advanced camera for tge in the resources, but it tries to find a dgl.h that exists nowhere on my computer. I look at the demo to try to figure it out and I see things like:
%this.camera = new Camera()
%this.camera.scopeToClient(%this);

okay, so where is the documentation that lists what all is part of camera? is there a camera.setmode() ??
I don't know. I can't find the documentation. I'm sure I can probably figure it out by wading through all the source code, but I'd prefer if I didn't have to. Surely someone has a list somewhere?
