Provides an identical interface to
:pythonlib:`optparse`.OptionParser, in addition, it displays an
automatically generated `wx <http://www.wxpython.org>`_ dialog in order to enter the
options/args, instead of parsing command line arguments.
This code is based on `optparse_gui module
<http://code.google.com/p/optparse-gui/>`_. Unfortunately the owner of
optparse_gui did not respond to a request to join the optparse_gui
group. By now this module has become more complete with more features.
