+
+:abstract: This document describes generateds_ui.py, the graphical
+    front end to generateDS.py.
+
+Introduction
+==============
+
+``generateds_gui.py`` provides a graphical front end for
+``generateDS.py``.  Some may find it easier to configure and to
+select and set options for ``generateDS.py`` using this graphical
+application.
+
+
+Requirements
+==============
+
+You will need Gtk support for Python in order to run
+``generateds_gui.py``.
+
+You must run ``generateds_gui.py`` under Python 3.  Python 2 is not
+supported.
+
+Note that you can use the "--session" command line flag supported by
+``generateDS.py`` on a machine that does not have Python Gtk support
+installed.
+
+
+Usage notes
+=============
+
+What it does
+--------------
+
+Here are some of the different ways that you can use
+``generateds_gui.py``:
+
+#. You can generate modules from within ``generateds_gui.py`` using
+   the "Generate" item in the "Tools" menu.
+
+#. You can produce and view a command line that reflects your
+   configuration using the "Generate CL" item in the "Tools" menu,
+   and then you can copy and paste the resulting command line into a
+   ``bash`` script (for Linux) or a ``.bat`` file (for MS Windows),
+   which you can then run from the command line.
+
+#. You can run the session file that you've saved with the
+   "--session" command line flag supported by ``generateDS.py``.
+
+#. You can load a previously saved session file into
+   ``generateds_gui.py`` using the "--session" command line option,
+   and then modify that session and/or use it to generate modules,
+   or to generate a command line.
+
+
+How to use it
+---------------
+
+You can get some help by running the following::
+
+    $ ./generateds_gui.py --help
+
+Command line options and arguments::
+
+	Usage:
+        python generateds_gui.py [options] --session=<some_session_file.session>
+	example:
+		python generateds_gui.py --session=generator01.session
+	Options:
+	  -h, --help            show this help message and exit
+	  --exec-path=EXEC_PATH
+							path to executable generated in command line.
+							Example: "python /path/to/generateDS.py".  Default:
+							"./generateDS.py".  Use Tools/Generate CL (Ctrl-T) to
+							see it.
+	  --impl-gui=IMPL_GUI   name of glade file that defines the GUI if not
+							embedded.
+	  -s SESSION, --session=SESSION
+							name of a session file to be loaded.
+
+exec-path
+    If your copy of ``generateDS.py`` is in a special location, you
+    can specify that location using this option.  The version of
+    ``generateDS.py`` at that location will be run when you select
+    the "Generate" item from the "Tools" menu.
+
+impl-gui
+    The file ``generateds_gui.glade`` specifies and describes the
+    user interface.  This file has been embedded into
+    ``generateds_gui.py``.  If you modify ``generateds_gui.glade``
+    and want to use that modified version, specify it with this
+    option.
+
+s, session
+    If you have created and saved a session file using
+    ``generateds_gui.py`` and want to load that file the next time
+    you run ``generateds_gui.py``, use this option.  Alternatively,
+    once ``generateds_gui.py`` has been started, you can use the
+    "Load session" item under the "File" menu.
