# usage: git-repository--after-tarball [<tarballs>]
# with optional environment variables:
# - GIT_URL="git://xxx/foo.git [branch]"
# - GIT_REPOSITORY_CACHE=/zzz/foo.git
#
# the GIT_REPOSITORY_CACHE can be used with or without GIT_URL
# - if GIT_URL is given, GIT_REPOSITORY_CACHE will be a "bare" clone of GIT_URL
# - otherwise, GIT_REPOSITORY_CACHE can be created using:
#   % git clone --bare BUILD/foo-1 $GIT_REPOSITORY_CACHE
#   where foo-1 is the previous version
