Am I the only one... who documents things? I've seen only one other commit into APIDump's definitions, by STR (thank you, sir, for not letting me be alone in this); that is not what I'd call "active". Come on, is it really that difficult? Just pick a class, copy the skeleton from "undocumented.lua", open up the C++ header file declaring that class and copy over the functions' descriptions.
