@brief Construct simple wxPython GUI from a GRASS command interface
description.

Classes:
 - forms::UpdateThread
 - forms::UpdateQThread
 - forms::TaskFrame
 - forms::CmdPanel
 - forms::GUI
 - forms::GrassGUIApp

This program is just a coarse approach to automatically build a GUI
from a xml-based GRASS user interface description.

You need to have Python 2.4, wxPython 2.8 and python-xml.

The XML stream is read from executing the command given in the
command line, thus you may call it for instance this way:

python <this file.py> r.basins.fill

Or you set an alias or wrap the call up in a nice shell script, GUI
environment ... please contribute your idea.

Updated to wxPython 2.8 syntax and contrib widgets.  Methods added to
make it callable by gui.  Method added to automatically re-run with
pythonw on a Mac.

.. todo::
    verify option value types
