<P>
The <code>EventPortlet</code> interface allows
portlets receiving events.
<p>
Events are part of the action processing and must
be finished before the rendering phase can start.
Portlets can receive events issued by other portlets or
portlet container defined events.
<p>
Portlets should declare the events it would like to receive
via the <code>supported-processing-event</code> tag and events published
via the <code>supported-publishing-event</code> tag in the portlet
deployment descriptor.
<p>
The event model is a loosely coupled model where the wiring between
published and receiving events is done at the portal / portlet container
level.
