Version 2.0.0 (03/11/16):
        When building for the 'win32' target, 'mpwx_build_pyc.bat' now
        calls 'mx_config_py.bat' to ensure that the Windows version of
        Python is used rather than the Cygwin version.  This makes it
        possible to build the win32 .pyc file from a Cygwin bash shell.

        Various minor appearance tweaks.

Version 1.5.4 (05/10/11):
        Added support for Windows.  Tested on Windows XP.

Version 1.5.2 (03/30/10):
        MpWx widgets now test for the existence of the MX network field
        at startup time.

        Received one-element lists are now converted into scalars.

Version 1.5.1 (10/05/09):
        Added 'base' keyword to the MpWx.Value widget.  Specifying 8, 10,
        or 16 for the base causes the widget to display its value in the
        requested base.

        Added 'reverse_order' keyword for the MpWx.RadioBox widget.

        The value changed callback code for MpWx has been changed so that
        if multiple widgets point at the same network field, then all of
        the widgets share the same callback.

        Modified the value changed callback function signature to include
        the network field object (Mp.Net) as the first argument of the
        callback function.

Version 1.5.0 (11/16/08):
        Initial release.
