-/* This example shows how to work with the state profile of a host or a link,
- * specifying when the resource must be turned on or off.
- *
- * To set such a profile, the first way is to use a file in the XML, while the second is to use the programmatic
- * interface. Once this profile is in place, the resource will automatically be turned on and off.
- *
- * The actors running on a host that is turned off are forcefully killed
- * once their on_exit callbacks are executed. They cannot avoid this fate.
- * Since we specified on_failure="RESTART" for each actors in the XML file,
- * they will be automatically restarted when the host starts again.
- *
- * Communications using failed links will .. fail.
