[PyQt] Using PyQT under the MIT license?

Hi all,

So after a little bit of digging I saw that Qt itself allows for some
other open source licenses
(http://doc.trolltech.com/4.4/license-gpl-exceptions.html) including
MIT License, which is my favourite no nonsense license. I'm
maintaining a couple of open source python scripts under the MIT
license and was toying with the idea of adding a user friendly GUI to
them, Qt and PyQT are looking pretty good since Tkinter is ugly and
almost all the other toolkits just fails abysmally under Win64
environments. Now I ran into a little bit of a snag, I can not find a
similar exception list to the GPL license for PyQT as for Qt itself.
The only thing I did find was
... except the wording "If you use the GPL versions then your own code
must also use a compatible license." could be interpreted either way,
compatible with GPL, or compatible with the license for Qt itself,
which *does* allow for MIT license. Oh how I hate licenses...

Could anyone clarify what that last sentence refers to? I want to
interpret it as it's free for the MIT license, but of course I'm
slightly biased.


Beware of architect astronauts.
