I looked at that first and it looked complicated and I didn't
understand it. If the ability to incorporate submitted third
party patches into a commercial derived work covered by this
section:
2.2. Contributor Grant.
Each Contributor hereby grants You a world-wide,
royalty-free, non-exclusive license, subject to third party
intellectual property claims:
(a) to use, reproduce, modify, display, perform,
sublicense and distribute the Modifications created by
such Contributor (or portions thereof) either on an
unmodified basis, with other Modifications, as Covered
Code or as part of a Larger Work; and
What other advantages (other than `redistribution in the form of
patches' for Qt and not for NPL) does the NPL have compared to
the Qt license? Now if the time for me to ask my friend to
switch licenses again. Thanks!
Peter
