     XZ Utils Licensing
     ==================

         Different licenses apply to different files in this package. Here
         is a summary of which licenses apply to which parts of this package:

           - liblzma is under the BSD Zero Clause License (0BSD).

           - The command line tools xz, xzdec, lzmadec, and lzmainfo are
             under 0BSD except that, on systems that don't have a usable
             getopt_long, GNU getopt_long is compiled and linked in from the
             'lib' directory. The getopt_long code is under GNU LGPLv2.1+.

           - The scripts to grep, diff, and view compressed files have been
             adapted from GNU gzip. These scripts (xzgrep, xzdiff, xzless,
             and xzmore) are under GNU GPLv2+. The man pages of the scripts
             are under 0BSD; they aren't based on the man pages of GNU gzip.

           - Most of the XZ Utils specific documentation that is in
             plain text files (like README, INSTALL, PACKAGERS, NEWS,
             and ChangeLog) are under 0BSD unless stated otherwise in
             the file itself. The files xz-file-format.txt and
             lzma-file-format.xt are in the public domain but may
             be distributed under the terms of 0BSD too.

           - Translated messages and man pages are under 0BSD except that
             some old translations are in the public domain.

           - Test files and test code in the 'tests' directory, and
             debugging utilities in the 'debug' directory are under
             the BSD Zero Clause License (0BSD).

           - The GNU Autotools based build system contains files that are
             under GNU GPLv2+, GNU GPLv3+, and a few permissive licenses.
             These files don't affect the licensing of the binaries being
             built.

           - The 'extra' directory contains files that are under various
             free software licenses. These aren't built or installed as
             part of XZ Utils.

         The following command may be helpful in finding per-file license
         information. It works on xz.git and on a clean file tree extracted
         from a release tarball.

             sh build-aux/license-check.sh -v

         For the files under the BSD Zero Clause License (0BSD), if
         a copyright notice is needed, the following is sufficient:

         If you copy significant amounts of 0BSD-licensed code from XZ Utils
         into your project, acknowledging this somewhere in your software is
         polite (especially if it is proprietary, non-free software), but
         it is not legally required by the license terms. Here is an example
         of a good notice to put into "about box" or into documentation:

             This software includes code from XZ Utils <https://tukaani.org/xz/>.

         The following license texts are included in the following files:
