Tribes 2... again

Basically here's the deal. I'm investigating purchasing the torque engine but want to do a little research. Low and behold i happen to have in my possesion a copy of tribes 2. I'm trying to experiment with the scripting to see what the engine is capable of, but I'm having a hard time tracking down any sort of documentation. Like description of data blocks and parameters to functions.

I'm trying to build a "Total Conversion" of sorts and just throw all the tribes 2 script away. But I need more information about the functions and where to start... I've been poking at it and making progress but it's going quite slowly.

Also, assuming i do make a "Total Conversion" then i buy torque. How easy would it be to port over? Hopefully someone can clear this confusion. Thanks.
