- Grassland mapsets

Anyone out there using Grassland1.0 under Unix? I have been playing with the
Solaris binary + scripts that was made available on LAS's ftp site a few years
ago.

I have got it to read a legacy dataset OK, but it seems to keep generating this
phantom mapset named "ecs_r_*", as well as over-writing my GISRC file every run.
A look at the scripts doesn't shed any light, and I am wondering whether this
behaviour is hard-coded somehow. Any ideas?
