Sorry if I gave you the impression that I am a skilled programmer in C.
Actually, I forgot the majority of GRASS modules are in C (or python now).
I always use shell scripts to do my stuff, so I was actually thinking of
Shell (what would be much easier to tweak).

My God, it is indeed complex! I guess, somehow by including stats.h, they
are done by a simple call to the functions (somewhere, because I can't see
either),
so he is not implementing the calculations in the code.

Well, at least that is my most humble (and ignorant) opinion.

Cheers,
Marcello.
