[GRASS-dev] No "overwrite" option in grass 7 addon scripts?

[Isaac Ullah]

Thank you Anna and Markus. The help is very much appreciated! I will read
the linked documentation, and I will review Anna's proposed changes to
r.viewshed.cva and merge them.

May I also suggest that the documentation of the use of "new" for output
files be added to the example code in the g.parser man page (
http://grass.osgeo.org/grass70/manuals/g.parser.html)? That would make it a
lot easier to find for new script writers...

Cheers,

~Isaac
