Plugins allow for easy extensibility and customization of the framework.
</para>
<para>
Plugins are classes. The actual class definition will vary based on the
component -- you may need to implement this interface, but the fact
remains that the plugin is itself a class.
</para>
<para>
A plugin could be loaded into Yaf by using
<methodname>Yaf_Dispatcher::registerPlugin</methodname>, after
registering, All the methods which the plugin implemented according to this
interface, will be called at the proper time.
