[GRASS-dev] GRASS and sextante

[Benjamin Ducke]

Theoretically, it wouldn't be very hard to read the labels
from the mapset in which SEXTANTE is storing the (temporary)
GRASS datasets; they are saved as plain ASCII there.

However, the host GIS for SEXTANTE must then somehow deal
with this additional data in some useful way (e.g. via a 
virtual raster attribute table).
