+ * KDED Module to handle shortcut icons ("favicons")
+ * FaviconsModule implements a KDED Module that handles the association of
+ * URLs and hosts with shortcut icons and the icons' downloads in a central
+ * place.
+ *
+ * After a successful download, the DCOP signal iconChanged() is emitted.
+ * It has the signature void iconChanged(bool, QString, QString);
+ * The first parameter is true if the icon is a "host" icon, that is it is
+ * the default icon for all URLs on the given host. In this case, the
+ * second parameter is a host name, otherwise the second parameter is the
+ * URL which is associated with the icon. The third parameter is the
+ * @ref KIconLoader friendly name of the downloaded icon, the same as
+ * @ref iconForURL will from now on return for any matching URL.
+ *
+ * @short KDED Module for favicons
