as Heiko Kehlenbrink pointed out, s.geom was the only command
able to compute the convex hull of a site point and now
has gone away. This weekend I have coded s.hull, a free (GPL)
replacement to compute a convex hull. Markus provided also
some nice addictions and has put it in the current CVS so
that everyone interested can use it. I've tested it a bit
with random site files and prevented some ill site file configurations
(such as trying to calculate the hull over two points only),
everything seems to work properly.
