GRASS GIS $NAME_VER binary package installation tool

Usage:	grass-$NAME_VER-install.sh grass-$NAME_VER.tar.gz [dest_dir] [bin_dir]

      with:
        [dest_dir] - optional: FULL path name to the installation directory
                     (default: /usr/local/grass$NAME_VER/)
        [bin_dir] - optional: FULL path name to the grass binary directory
                     (default: /usr/local/bin/)
		     Notes: 1) Only the grass executable file is stored here
		     	    2) If you want to change the binary directory only
			       then you need to specify the destination
			       directory as well

You may need login as root for installation.
