# MODULE: d.path_wrapper.sh
# AUTHOR(S): Hamish Bowman (Otago University, New Zealand)
# PURPOSE: Draw vector map to xmon before running d.path and pass opts
# COPYRIGHT: (c) 2007 by Hamish Bowman, and the GRASS Development Team

# This program is free software under the GNU General Public

#############################################################################
# Notes:
# Created with "d.path --script" from GRASS 6.3-CVS 6 March 2007
# Be sure menu entry runs guarantee_xmon first. for example:
# "guarantee_xmon; d.path_wrapper.sh -b --ui"
# d.path is interactive with the xmon, but does not need to run in a xterm
