[GRASS-dev] Re: [GRASS5] [bug #4331] (grass) delete if file exist - flag

Hey,

The help output for modules using a "new,*" gisprompt now includes the --o 
flag. It's omitted from the xml output because it doesn't fit the current 
scheme.

G_parser now sets, but doesn't export, the OVERWRITE environment variable.

No need for this since it's working for scripts now.

I'd have done it that way ;)
