\endcode

*
|

* Kopete::Plugin inherits from KXMLGUIClient. That client is added
|
|
* to the Kopete's mainwindow KXMLGUIFactory. So you may add actions
|
|
* on the main window (for hinstance in the meta contact popup menu).
|
|
* Please note the the client is added right after the plugin is created.
|
