Unreal Tournament - UnrealScript documentation

I was googling for some info about a UT actor, and found this nice site:

Unreal Tournament - UnrealScript Documentation

If you're into UnrealScript, this is a handy, online reference for all things Unreal and UT. Everything's clickable, so you can view the whole class tree. So for example, the LoopMover that I posted about, you can view its specific variables, as well as what it inherits from Engine.Mover.

So when you're writing your own mod or mutator, you can choose the appropriate actor and inherit from that. Or something.
