r.pack collects raster map elements and support files and
compressed them using gzip algorithm for copying. The resulting
packed file can be afterwards unpacked within a GRASS GIS session
by r.unpack.
Since the selected raster map is not exported but natively stored, the
current region is not respected. Hence r.pack stores the entire
raster map.
NOTES
By default, the name of the pack file is determined from the input
parameter. Optionally a different name can be given by output parameter.
Currently only 2D raster maps are supported.
EXAMPLE
Pack up the entire raster map aspect into aspect.pack file:
r.pack input=aspect
The packed raster map file aspect.pack can afterwards be unpacked by
