Warning:
PyQwt_Qt230-3.8.win32-py2.3.exe is the latest ``non-commercial'' version of PyQwt on Window for
QtWin230-NonCommercial.exe and
PyQt-win-nc-3.8.exe, because Trolltech and Riverbank Computing have
discontinued their non-commercial software. Hopefully, this situation will
change with the availability of a new book on Qt programming including a
non-commercial version of Qt-3.2.
I will try to keep PyQwt-3.10.tar.gz working with the commercial releases
of Qt and PyQt on Windows, but the installation instructions for Windows may
be inaccurate or obsolete.
