+# Purpose {{{
+##	This script will check if some Ceph related Debian packages are available
+##		in APT cache.
+##	And backup all of them (ceph, rados, rbd,…) in tar with version name and date.
+#
+##	You can use this script in a cron (for periodic backup of Ceph packages) or
+##		directly.
+# }}}
