+/* This example shows how to work with the state profile of an 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 an host that is turned off will receive a simgrid::HostFailureException. 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.
