+ * SECTION:hb-gobject
+ * @title: hb-gobject
+ * @short_description: GObject integration support
+ * @include: hb-gobject.h
+ *
+ * Support for using HarfBuzz with the GObject library to provide
+ * type data.
+ *
+ * The types and functions listed here are solely a linkage between
+ * HarfBuzz's public data types and the GTypes used by the GObject framework.
+ * HarfBuzz uses GObject introspection to generate its Python bindings 
+ * (and potentially other language bindings); client programs should never need
+ * to access the GObject-integration mechanics.
+ *
+ * For client programs using the GNOME and GTK software stack, please see the
+ * GLib and FreeType integration pages.
