zint (libzint), the barcode generator compiled into zxing_reader.wasm
=====================================================================

zint does not ship its BSD 3-Clause grant as a standalone file. The grant lives
as a header comment on every source file, and the text below is that grant,
reproduced verbatim from backend/zint.h at https://github.com/zint/zint. zint's
own LICENSE file, which records the 2013 relicensing away from the GPL and the
two conditions attached to it, follows after it.

Plume reaches zint through zxing-cpp, which carries it as a submodule; the copy
in public/zxing/3.1.1/zxing_reader.wasm was built from zxing-cpp at commit
6c2961d2a9ea4bc4e4ae8f37b1497299f04dd861.

=== zint's own LICENSE file, verbatim =================================

ZINT was originally developed by Robin Stuart and licensed under the terms of the GPL (Gnu
Public License). In 2013 Robin Stuart and all developers that contributed to the code agreed
to change the license to a less restrictive one (see ZINT mailing list of May 2013 for
related mails) under the following conditions:
- the names of original copyright holder Robin Stuart and contributors are not removed,
  neither from sources nor from the manual
- the documentation is done in British English (as Robin said: "Oh, and please don't
  replace the word "colour" with "color" in the documentation - that really annoys me!")

Change to BSD-license is done for backend and therefore for ZINT shared library only, for
the frontends and Qt4-backend the GPL is still valid. Since BSD-license is GPL-compatible
this gives the possibility to include ZINT library in own products or link against it from
own software.
