+# Purpose {{{
+## Create a temp file (to monitor) if an upgrade is available for Ceph
+## project on Github.
+## It's based on .deb package (or repository) installation to check the
+## current version.
+## How-to use {{{
+### 1. Needs releasetags script, in the same directory
+### cf. https://git.ipr.univ-rennes1.fr/cellinfo/scripts/src/master/github/releasetags
+# wget https://git.ipr.univ-rennes1.fr/cellinfo/scripts/raw/master/github/releasetags
+### 2. Create a cron job, eg :
+#00 20 * * * root /opt/repos/ipr.scripts/github/check.ceph.update
+### 3. Monitor the temp file : /tmp/.github.ceph.upgrade
+# Or enable MAILTO in cronjob and edit the script to print a message.
+# Or send a mail.
+# …
+## }}}
