[OSGeo-Discuss] use of color palettes with vector data

[Stéphanie Faroux]

Hello Markus,
Now I will use the grass user list as you suggest.
Thank you for your answer; as i'm a recent grass user, could you confirm 
this is what to do to get your update:

  svn checkout https://svn.osgeo.org/grass/grass-addons grass-addons
  
  #Subsequent updates:
  svn up

Thank you
Best regards
Stéphanie
