 * @ingroup settings
 * @ingroup plugin
 * @short Convenience TDECModule for creating a plugins config page.
 *
 * This class makes it very easy to create a plugins configuration page to your
 * program. All you need to do is create a class that is derived from
 * PluginPage and add the appropriate plugin infos to the KPluginSelector.
 * This is done using the pluginSelector() method:
 * \code
 * typedef KGenericFactory<MyAppPluginConfig, TQWidget> MyAppPluginConfigFactory;
 * K_EXPORT_COMPONENT_FACTORY( kcm_myapppluginconfig, MyAppPluginConfigFactory( "kcm_myapppluginconfig" ) );
 *
 * MyAppPluginConfig( TQWidget * parent, const char *, const TQStringList & args )
 *     : PluginPage( MyAppPluginConfigFactory::instance(), parent, args )
 * {
 *     pluginSelector()->addPlugins( TDEGlobal::instance()->instanceName(), i18n( "General Plugins" ), "General" );
 *     pluginSelector()->addPlugins( TDEGlobal::instance()->instanceName(), i18n( "Effects" ), "Effects" );
 * }
 * \endcode
 *
 * All that remains to be done is to create the appropriate .desktop file
 * \verbatim
