[Eriberto Mota <eriberto@debian.org>]

Hi guys,

This bug also affects png-definitive-guide.

The license text says (from copyright.html):

Permission is granted to copy, distribute, and/or modify this document
under the terms of the GNU Free Documentation License, Version 1.1 or
any later version published by the Free Software Foundation; with no
Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A

Lintian says:

E: png-definitive-guide source: license-problem-gfdl-invariants
copyright.html invariant part is: with no invariant sections, e-mail
from laurie petrycki, 20030726: no front-cover texts, and no
back-cover texts. end

(yes, the litian message has an e-mail and ends with "end").

Regards,

Eriberto
