Hi there.
I'm working with grass and found a executable named XDRIVER.
I need to know what does it do. So I wanted to know where to find info on thi
s...
If someone could help me I would be grateful.
If you're working with GRASS in the sense of having already
used it, don't worry about XDRIVER 
GRASS does that for you.
In case you still want to know:
The GRASS command d.mon starts XDRIVER for you. In detail:
If you use 'd.mon start=x0', d.mon looks for 'x0' in the
file $GISBASE/etc/monitorcap and finds a line starting with
x0:driver/XDRIVER:X-windows graphics display:
This tells it that it should start the executable
$GISBASE/driver/XDRIVER under the name of x0 - which is what
it does. Pop - there's your GRASS Monitor!
Hope I didn't confuse things too much (and hope this
is indeed what happens )
