+ * SECTION:gtkplug
+ * @Short_description: Toplevel for embedding into other processes
+ * @Title: GtkPlug
+ * @include: gtk/gtkx.h
+ * @See_also: #GtkSocket
+ *
+ * Together with #GtkSocket, #GtkPlug provides the ability to embed
+ * widgets from one process into another process in a fashion that is
+ * transparent to the user. One process creates a #GtkSocket widget
+ * and passes the ID of that widget's window to the other process,
+ * which then creates a #GtkPlug with that window ID. Any widgets
+ * contained in the #GtkPlug then will appear inside the first
+ * application's window.
+ *
+ * The communication between a #GtkSocket and a #GtkPlug follows the
+ * <ulink url="http://www.freedesktop.org/Standards/xembed-spec">XEmbed</ulink>
+ * protocol. This protocol has also been implemented in other toolkits,
+ * e.g. <application>Qt</application>, allowing the same level of
+ * integration when embedding a <application>Qt</application> widget
+ * in GTK+ or vice versa.
+ *
+ * <note>
+ * The #GtkPlug and #GtkSocket widgets are only available when GTK+
+ * is compiled for the X11 platform and %GDK_WINDOWING_X11 is defined.
+ * They can only be used on a #GdkX11Display. To use #GtkPlug and
+ * #GtkSocket, you need to include the <filename>gtk/gtkx.h</filename>
+ * header.
+ * </note>
