+ * @Short_description: A bin with a decorative frame and optional label
+ * @Title: GtkFrame
+ *
+ * The frame widget is a Bin that surrounds its child
+ * with a decorative frame and an optional label.
+ * If present, the label is drawn in a gap in the
+ * top side of the frame. The position of the
+ * label can be controlled with gtk_frame_set_label_align().
+ *
+ * <refsect2 id="GtkFrame-BUILDER-UI">
+ * <title>GtkFrame as GtkBuildable</title>
+ * <para>
+ * The GtkFrame implementation of the GtkBuildable interface
+ * supports placing a child in the label position by specifying
+ * "label" as the "type" attribute of a <child> element.
+ * A normal content child can be specified without specifying
+ * a <child> type attribute.
+ * </para>
+ * <example>
