-+ -----
-+
-+Flags are, syntactically, just like actions; their semantical value is different however.
-+Instead of doing something, they instead change the general behavior of the processing
-+of the given rule.
-+
-+Note that for flags to work, you also have to invoke it with --override.
-+
-+Currently, only one flag is implemented:
-+
-+ * nothrottle
-+ 	Forcibly overrides hotplug2 throttling mechanism. If _all_ rules that match
-+	the given kernel event have 'nothrottle' set, hotplug2 will not wait for
-+	children count to get under max-children limit. That allows to throttle
-+	eg. helper application execution or modprobes, but yet keep node devices
-+	fast.
