        For performance reasons, Thuban access wxPython objects at the
        C++ level so that it can directly call wxWidgets code from C++.
        The normal and preferred way to do that is to use the API
        defined in wxPython.h.  Unfortunately, this header file is not
        distributed with binary packages of wxPython on some platforms.
        By using the --use-wx-python-swig-hack option you can activate a
        way to access the C++ objects without wxPython.h.  This relies
        on internals of SWIG, so it might change with future wxPython
        versions.  Therefore, only use this option if the normal way
        doesn't work for you.
