Need some directions.

Hi, I need someone to tell me whereabout is the source file that implements mask (bruteforce) word's generation.
I want to tweak it so that it will be able to work on all lengths in the same time and also use my special algorithm (only when not using markov).
You can already try it on my fork of john the ripper at https//github.com/e2002e/john
, using mask after having compiled the code from branch 'rain'.

I understand mask is treated with mpsp.c but can't find a clue as how the state evolves and also how total count is managed.
