# Since there is no fetch hooks, and we don't want to complicate
# this more than necessary, we use throw disk space and cpu at it.
#
# Two stages: a bare copy that we mirror into, and then a separate
# local copy that we push to to get the hooks running as expected.
#
# Time will tell if this is a good idea or not. I don't fancy parsing
# stuff in .git by myself.
