	To aid custom scripting, {{cmd\|g.region}} in GRASS 6.5+ supports the ''-t'' flag to output the current region in GMT's <tt>W/E/S/N</tt> region format.		To aid custom scripting, {{cmd\|g.region}} in GRASS 6.5+ supports the ''-t'' flag to output the current region in GMT's <tt>W/E/S/N</tt> region format. Both GMT and GRASS support the D:M:Sh notation for latitude and longitude.
