Here is a diagram:

# GRASS 6

# GRASS 7

There are many functions available. You don't necessarily need to touch
the map files you found "manually" but better use the appropriare
raster functions (either the C functions or for example Python functions
made available through the SWIG wrapper).

See above links for the Programmer's Manual.
