        <application>Gi-DocGen</application> is a document generator for
        GObject-based libraries. GObject is the base type system of the GNOME
        project. GI-Docgen reuses the introspection data generated by
        GObject-based libraries to generate the API reference of these
        libraries, as well as other ancillary documentation.
