33 * SECTION:hb-gobject
34 * @title: hb-gobject
35 * @short_description: GObject integration support
36 * @include: hb-gobject.h
37 *
38 * Support for using HarfBuzz with the GObject library to provide
39 * type data.
40 *
41 * The types and functions listed here are solely a linkage between
42 * HarfBuzz's public data types and the GTypes used by the GObject framework.
43 * HarfBuzz uses GObject introspection to generate its Python bindings
44 * (and potentially other language bindings); client programs should never need
45 * to access the GObject-integration mechanics.
46 *
47 * For client programs using the GNOME and GTK software stack, please see the
48 * GLib and FreeType integration pages.
