add a centroid.

If you use the latest development snapshot, you can also use v.centroid 
(http://grass.itc.it/grass63/manuals/html63_user/v.centroids.html), but 
actually it is just a wrapper around v.category:

v.category input=inputmap output=outputmap option=add type=area layer=1 
cat=starting_value_for_categories step=step_of_cat_value_increment
