grassu-list:
Ronald Wiemer, ARCHIS, The Netherlands (ronald@archis.nl),
recently shared a shell script that can quickly display
the outline of the current region.
I used his script as the basis of a script that can be used
to display the outline of any region stored in a windows directory
in the current mapset searchpath. This might be useful to outline
areas of interest ('insets') or to help find predefined areas.
Usage: d.region.sh region_file color
Default drawing color can easily be changed by editing line 3.
This is just a simple Bourne shellscript and it might have some bugs.
Any feedback would be appreciated.
