1. The crude but simple way:

	eval `g.gisenv`
	LOCATION=$GISDBASE/$LOCATION_NAME/$MAPSET
	export GISDBASE LOCATION_NAME MAPSET LOCATION

2. The slightly longer way:

	eval `g.gisenv get=GISDBASE`
	eval `g.gisenv get=LOCATION_NAME`
	eval `g.gisenv get=MAPSET`
	LOCATION=$GISDBASE/$LOCATION_NAME/$MAPSET
	export GISDBASE LOCATION_NAME MAPSET LOCATION

Option 2 has the advantage of not consuming excessive environment
space when there are lots of settings in $GISRC.
