To use, simply do: # # cd $GIT_DIR; git-archive-all.sh # # where $GIT_DIR is the root of your git superproject. # # License: GPL3 # ############################################################################### # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
