[GRASS-user] Update of vector table through selections in the map

[Andreas Philipp]

Hi,

I've done a bit more work on that crude script v.digatt and it is posted now 
to: http://grass.gdf-hannover.de/wiki/GRASS_AddOns#Vector_add-ons (last entry 
at moment). The script is just tested for dbf driver, linux and just for line 
and point objects. 

Cheers,
Andreas
