	It is going into the tree tonight, but will not have an
installation script or be part of the overall degas makefile system for
just a bit.  It doesn't sound like that is an issue for you anyway.

	Download it and have a look.  It'll be in CVS in a couple of 
hours, so from now on you can get updates by anon CVS or the daily snapshots.
