+ *
+ * #ClutterAction is an abstract base class for action that modify the
+ * user interaction of a #ClutterActor, just like #ClutterEffect is an
+ * abstract class for modifiers of the appearance of a #ClutterActor.
+ *
+ * Implementations of #ClutterAction are associated to an actor and can
+ * provide behavioral changes when dealing with user input - for instance
+ * drag and drop capabilities, or scrolling, or panning.
+ *
+ * #ClutterAction is available since Clutter 1.4
