Appendix E Open Source Licences
The wxWindows Licence is essentially the L-GPL (Library General Public Licence),
with an exception stating that derived works in binary form may be distributed on
the user's own terms. This is a solution that satisfies those who wish to produce
GPL'ed software using wxWidgets, and also those producing proprietary software.
Participants in the discussion that led to this decision include the folk from
Abisource, Robert Roebling, Julian Smart, Markus Fleck, Karsten Ballueder, and
some advice from Richard Stallman. Richard has confirmed that the new licence is
compatible with GPL'ed applications. However, there are no significant restrictions
on proprietary applications.
The wxWindows Licence has been approved by the Open Source Initiative, and
you can find the licence on their site here.
In August 2005, an ambiguity in Clause 2 was removed (replaced "the user's" with
"your") and the version bumped to 3.1.
