+ * This script is intended to be run through cron.
+ * It should look through the postfixadmin vacation table for vacation entries that should no longer be active. If it
+ * finds one that's expired, it should update the alias record to remove the autoreply alias, as well as deactivating the vacation entry.
+ * @see https://github.com/postfixadmin/postfixadmin/issues/832
+ *
+ * How you link it into your cron routine is up to you - you 'could' have an entry in /etc/cron.hourly/postfixadmin that contains something like : 
+ *
+ * #!/bin/bash
+ * cd /path/to/postfixadmin/scripts/examples
+ * php vacation-cron.php
+ *
+ *
+ * might work.
