DESCRIPTION
r.out.gdal outputs GRASS raster maps into various GIS formats
as supported by GDAL. This script is based on 'gdal_translate',
it's parameters are similar to those of
'gdal_translate'.
For possible metaopt parameters see the 'supported formats' pages
of GDAL.
The createopt may be used to create TFW or World files ("TFW=YES",
"WORLDFILE=ON").
