I wanted to this a while back and got the following script working.  I then
decided that I didn't really want to do it at all so I havn't much experience
to tell you about ...  I doubt that all the setenv's are actually needed.

---------------   cut here  ---------------
#!/usr/local/bin/tcsh

set path= (/user/grass4.1beta/sun4/bin /user/grass4.1beta/sun4/scripts /user/grass4.1beta/sun4/garden/bin /user/grass4.1beta/sun4/alpha/bin /usr/local/bin /usr/bin /usr/ucb /etc /usr/etc /usr/lib)
setenv GISBASE /user/grass4.1beta
setenv GISDBASE /home/grass
setenv GISRC dss_grassrc
setenv LOCATION /home/grass/tyne/phil
setenv LOCATION_NAME tyne
setenv MAPSET phil

g.list rast
