[GRASS-dev] r.in.gdal to group automatically imported multi-bands image

[Yann Chemin]

Could it be possible to automatically get the list of images from the
group and take the 3 first bands as RGB, get these into a d.rgb string
and attach that to a display button inside each group by default, or
something similar...?

I do know really, just trying to get some improvement on the usability
feeling for image processing in GRASS GIS...

thanks
yann
