also, since opencl formats are registered in john.c
with a define we could add them
before the
cnt = dynamic_Register_formats(&pFmts);
in that way they become the default for that given format .
i don't know if it mess up with cpu formats.
btw i'm a bit unfamiliar with cuda but i think we can't merge them:
cuda is nvidia only therefore on nvidia cards it would compile but
that's not possible on ati .
about documentation there's a Redme.opencl on the doc dir, which is
something i did in the spare time.
unfortunately i'm still a noob with git and pull requeste so i will add
it here for simplicity
Cheers
Samuele
