-<pre>XZ Utils Licensing
-==================
-
-    Different licenses apply to different files in this package. Here
-    is a rough summary of which licenses apply to which parts of this
-    package (but check the individual files to be sure!):
-
-      - liblzma is in the public domain.
-
-      - xz, xzdec, and lzmadec command line tools are in the public
-        domain unless GNU getopt_long had to be 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 gzip. These scripts and their documentation are
-        under GNU GPLv2+.
-
-      - All the documentation in the doc directory and most of the
-        XZ Utils specific documentation files in other directories
-        are in the public domain.
-
-        Note: The JavaScript files (under the MIT license) have
-        been removed from the Doxygen-generated HTML version of the
-        liblzma API documentation. Doxygen itself is under the GNU GPL
-        but the remaining files generated by Doxygen are not affected
-        by the licenses used in Doxygen because Doxygen licensing has
-        the following exception:
-
-            "Documents produced by doxygen are derivative works
-            derived from the input used in their production;
-            they are not affected by this license."
-
-      - Translated messages are in the public domain.
-
-      - The build system contains public domain files, and files that
-        are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
-        in the binaries being built.
-
-      - Test files and test code in the tests directory, and debugging
-        utilities in the debug directory are in the public domain.
-
-      - The extra directory may contain public domain files, and files
-        that are under various free software licenses.
-
-    You can do whatever you want with the files that have been put into
-    the public domain. If you find public domain legally problematic,
-    take the previous sentence as a license grant. If you still find
-    the lack of copyright legally problematic, you have too many
-    lawyers.
-
-    As usual, this software is provided "as is", without any warranty.
-
-    If you copy significant amounts of public domain code from XZ Utils
-    into your project, acknowledging this somewhere in your software is
-    polite (especially if it is proprietary, non-free software), but
-    naturally it is not legally required. 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:
-      - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
-      - COPYING.GPLv2: GNU General Public License version 2
-      - COPYING.GPLv3: GNU General Public License version 3
-
-    Note that the toolchain (compiler, linker etc.) may add some code
-    pieces that are copyrighted. Thus, it is possible that e.g. liblzma
-    binary wouldn't actually be in the public domain in its entirety
-    even though it contains no copyrighted code from the XZ Utils source
-    package.
-
-    If you have questions, don't hesitate to ask the author(s) for more
-    information.
