* @brief Base class for all plugins or protocols.

Encoding=UTF-8
Type=Service
X-Kopete-Version=1000900
Icon=icon
ServiceTypes=Kopete/Plugin
X-TDE-Library=kopete_myplugin

X-TDE-PluginInfo-Depends=
X-TDE-PluginInfo-License=GPL
X-TDE-PluginInfo-EnabledByDefault=false
Name=MyPlugin
Comment=Plugin that do some nice stuff
\endverbatim
*
* The constructor of your plugin should looks like this:
*
* \code
typedef KGenericFactory<MyPlugin> MyPluginFactory;
static const KAboutData aboutdata("kopete_myplugin", I18N_NOOP("MyPlugin") , "1.0" );
K_EXPORT_COMPONENT_FACTORY( kopete_myplugin, MyPluginFactory( &aboutdata ) )
MyPlugin::MyPlugin( TQObject *parent, const char *name, const TQStringList & args )
: Kopete::Plugin( MyPluginFactory::instance(), parent, name )
{
//...
}
\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.
* so you have to create every actions in the constructor
