+Package event contains the definitions for the Event types produced by source.Sources and transformed into
+reconcile.Requests by handler.EventHandler.
+
+You should rarely need to work with these directly -- instead, use Controller.Watch with
+source.Sources and handler.EventHandlers.
+
+Events generally contain both a full runtime.Object that caused the event, as well
+as a direct handle to that object's metadata.  This saves a lot of typecasting in
+code that works with Events.
