# Usage Message
#------------------------------------------------------------------------------
if test $# -eq 0
then
    cat <<EOF

			    $0 usage:

batch-grass runs a command (or executes all commands in a file) in the
grass environment. It simply sets some environmental variables and executes
the commands.

	$0 location_name mapset command
	$0 location_name mapset -file filename

e.g.,

	$0 usgs PERMANENT -file make-quads

	exit 0
