+ * This class is a plugin which allows to synchronise access riths
+ * between InDefero and a common restricted SSH account for git
+ * access.
+ *
+ * As the authentication is directly performed by accessing the
+ * InDefero database, we only need to synchronize the SSH keys. This
+ * synchronization process can only be performed by a process running
+ * under the git user as we need to write in
+ * /home/git/.ssh/authorized_keys
+ *
+ * So, here, we are just creating a file informing that a sync needs
+ * to be done. We connect this plugin to the IDF_Key::postSave signal.
