[GRASS-user] Polygon density map?

Hi all,

I've imported a small subsection of a non-planar dataset into GRASS, 
which it quickly imported and built topology on. I want to find out how 
many overlapping categories exist within each polygon. Using:

   v.category in=mylayer option=print

displays the categories overlapping, but I need these to be associated 
with the intersecting polygons -- is there an easy way to achieve this?
