+ * The base class for KDED modules.
+ *
+ * In KDE 2 and KDE 3, KDED modules are realized as shared
+ * libraries that are loaded on-demand into kded at runtime.
+ *
+ * To write a config module, you have to create a library
+ * that contains at least one factory function like this:
+ *
+ * \code
+ *   extern "C" {
+ *     KDE_EXPORT KDEDModule *create_xyz(QCString *name)
+ *     {
+ *       return new XYZ(name);
+ *     }
+ *   }
+ * \endcode
+ *
+ * See kdelibs/kded/HOWTO for more detailed documentation.
