Assuming that the Corrade directory is at:

/var/Corrade

and that mono is installed at:

/usr/bin/mono

the following OSX plist will restart Corrade and keep the daemon running.

To install, copy the plist below to /Library/LaunchDaemons and load it using:

launchctl load -w net.was.secondlife.corrade.plist

net.was.secondlife.corrade.plist
