[Fedora-legal-list] pngquant dual-licensing note

[Sérgio Basto]

Hi, 
pngquant was relicense under GPLv3 [1] but after a short time author
added an exception and make pngquant as dual-licensed the latest
README.md says:

License

pngquant is dual-licensed:

    GPL v3 or later, and additional copyright notice must be kept for older parts of the
code. See COPYRIGHT for details.

    For commercial/closed-source/AppStore distribution please ask kornel(a)pngquant.org for
a license.


This is acceptable for include in Fedora ? 

Thanks,
