35 * Base class for plugins
37 * A base class for StatusNet plugins. Mostly a light wrapper around
38 * the Event framework.
40 * Subclasses of Plugin will automatically handle an event if they define
41 * a method called "onEventName". (Well, OK -- only if they call parent::__construct()
42 * in their constructors.)
44 * They will also automatically handle the InitializePlugin and CleanupPlugin with the
45 * initialize() and cleanup() methods, respectively.
