+# hook to simpler, pull-only repos
+# e.g. /git-slave/tophat.git on onelab.eu
+# the idea here is, we need to keep a local read-only mirror
+# of some repositories
+# instead of hacking this script that is already scary, I preferred to write
+# a separate script git-update.sh that runs a bit like auto-update.sh
+# and that additionally takes care of remote branches
+# the layout is as follows
+# * manually created the local mirror by running
+#   cd /git-slave
+#   git clone ssh://tophat@git.top-hat.info/tophat.git
+#   which creates a non-bare repo right under /git-slave
+# * create a symlink for git-daemon
+#   cd /git
+#   ln -s /git-slave/tophat/.git tophat.git
+# * enable updates by just dropping a symlink there
+#   cd /git-slave/tophat
+#   ln -s /root/infrastructure/scripts/git-udate.sh
