# File: git-archive-all.sh
#
# Description: A utility script that builds an archive file(s) of all
# git repositories and submodules in the current path.
# Useful for creating a single tarfile of a git super-
# project that contains other submodules.
#
# Examples: Use git-archive-all.sh to create archive distributions
# from git repositories. To use, simply do:
#
# cd $GIT_DIR; git-archive-all.sh
#
# where $GIT_DIR is the root of your git superproject.
