Optionally create a new deluge user for running the service: ​http://support.apple.com/kb/PH6651

To create a LaunchDaemon for Deluge, create /Library/LaunchDaemons/com.deluged.plist using the script below. This script uses user 'deluge', created in the first step so replace if other user required.

Note: The path to deluge assumes installation using Macports and will need modified if using Deluge.app.
