[GRASS-dev] Overwrite flag in Grass70 python scripts with grass.script.array array ?

[Johannes Radinger]

Thank you Luca,

the problem was that in the options settings the parameter gisprompt for
the output did not contain "new". After changing the line to gispromt: new,
the overwrite option was available.
Thank you for the tip with the "grass.overwrite()" which returns TRUE if
overwrite is set.

/Johannes
