Qt to be licensed under the LGPL

[Nikos Chantziaras]

I'm posting this here since there was some discussion in the past about
using the Qt GUI library for interpreters and possibly other tools. As
of Qt 4.5, Nokia (they bought Trolltech) announced that it will be
licensed under the LGPL too, permitting non-GPL (and also non-open
source) projects to use it:

In one of my own projects (QTads), I had to ask Mike Roberts to grant
special permission to distribute the TadsVM reference implementation
included in QTads under the GPL in order to make a port possible. If
anyone out here is doing something similar right now, the good news is
that you don't need to relicense your code anymore to use Qt.
