+ * @Short_description: Functions for controlling drag and drop handling
+ * @Title: Drag and Drop
+ *
+ * GTK+ has a rich set of functions for doing inter-process
+ * communication via the drag-and-drop metaphor. GTK+
+ * can do drag-and-drop (DND) via multiple protocols.
+ * The currently supported protocols are the Xdnd and
+ * Motif protocols.
+ *
+ * As well as the functions listed here, applications
+ * may need to use some facilities provided for
+ * <link linkend="gtk-Selections">Selections</link>.
+ * Also, the Drag and Drop API makes use of signals
+ * in the #GtkWidget class.
