LAUNCHING GRASS FROM A SCRIPT?

[Randy Hills]

We have launched Grass programs and scripts from cron with good results.  
Two things to watch for:  one, Grass lock files (make sure they're set 
and removed by the script) and two, leftover temporary files in the .tmp 
directory under your mapset.  The Grass script GIS.sh executes clean_temp 
which cleans these files up, but you don't want to remove these files 
while your script is running, but you might want it someplace in your 
script after its done doing Grass stuff.
