/*
* 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.
