The Dink Network

I'm trying to find a complete explanation of how to modify the ini file, most of the ones I've found just name each number, without actually explaining what they do. Some are obvious, but things like sequence number are not. It also needs to explain how to use SET_SPRITE_INFO. Anyone know of any tutorial that does all this?

EDIT: Preferably, it would also include what set_frame_special and the all caps commands like NOTANIM do.
