"""distutils extensions for GTK+/GObject/Unix

This module contains a Distribution subclass (GDistribution) which
implements build and install commands for operations related to
Python GTK+ and GObject support. This includes installation
of man pages and gettext/intltool support.

    The GDistribution class adds a number of commads and parameters
    related to GTK+ and GObject Python programs and libraries.

    Parameters (to distutils.core.setup):
      po_directory -- directory where .po files are contained
      po_package -- package name for translation files
      shortcuts -- list of .desktop files to build/install
      man_pages -- list of man pages to install

    Using the translation features requires intltool.

      from distutils.core import setup
      from gdist import GDistribution
