+# 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.
