Auto Updating the Application (including multiple servers)
You can use the command line tool sed.php to update the installations quickly by
running php sed.php update from the root installation folder. This will check if a new
version is available and if yes will download the setup pack and then confirm if it should be installed.
To do this without prompting for confirmation, use the -y flag.
php sed.php update -y
Add the above to a cron job to do this automatically.
