[wxWidgets.git] / wxPython / config.py

#----------------------------------------------------------------------
# Name:        wx.build.config
# Purpose:     Most of the contents of this module used to be located 
#              in wxPython's setup.py script.  It was moved here so
#              it would be installed with the rest of wxPython and
#              could therefore be used by the setup.py for other
#              projects that needed this same info and functionality
#              (most likely in order to be compatible with wxPython.)
#
#              This split from setup.py is still fairly rough, and
#              some things may still get shuffled back and forth,
#              refactored, etc.  Please send me any comments and
#              suggestions about this.

wxPython is a GUI toolkit for Python that is a wrapper around the
wxWidgets C++ GUI library.  wxPython provides a large variety of
window types and controls, all implemented with a native look and

on.
