/**
 * 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.
