There is a nice 10 minute tutorial for programmers of other languages here:

To use the GRASS SWIG/Python interface to libgis:
(work in progress; you can do most things with modules without this)

$ cd /usr/src/grass63/swig/python
$ make

GRASS> cd /usr/src/grass63/swig/python
GRASS> python
..
>>> import os, sys
>>> import python_grass6 as pyg6

>>> pyg6.G_gisinit('')

>>> mapset=pyg6.G_mapset()
>>> print mapset
user1
>>> print pyg6.G_database_unit_name(1)
meters
>>> print pyg6.G_database_projection_name()
UTM
>>> print pyg6.G_database_datum_name()
nad27
>>> pyg6.G_yes("Does it work?", 1)
Does it work?(y/n) [y] y
1
>>> print pyg6.G_getenv("GRASS_GUI")
