I was under the impression that r.in.gdal DID do this already (GRASS 6.1
anyway). e.g. r.in.onearth (r.in.wms) creates the group.

d.rgb group=groupname

could work if the was a consistant naming for bands, and the extension
could be predicted.

scan.r
scan.b
scan.c

but "r.in.onearth -l tmband=visual" creates:
satimage.1
satimage.2
satimage.3

for r,g,b?
