creation of polygons from points

This sounds like a standard Voronoi tessellation problem to me.  There is a
tar distribution called s.geom in /incoming on the moon site that contains
modules to generate these polygons with GRASS.

Someone posed a question to me about delineating polygons around
points (sites), sort of splitting the distance between points to create
a "polygon of influence" of each site. The sites are unequally distributed.

Would this best be done by converting the sites to a raster and using
r.neighbors or an r.mapcalc statement to "grow" the site cells?

Advice would be appreciated--- thanks in advance
