+ .
+     XZ Utils releases 5.4.6 and older and 5.5.1alpha have a

+ .
+     There is very little *practical* difference between public
+     domain and 0BSD. The main difference likely is that one
+     shouldn't claim that 0BSD-licensed code is in the public
+     domain; 0BSD-licensed code is copyrighted but available under
+     an extremely permissive license. Neither 0BSD nor public domain
+     require retaining or reproducing author, copyright holder, or
+     license notices when distributing the software. (Compare to,
+     for example, BSD 2-Clause "Simplified" License which does have
+     such requirements.)
+ .
+ If you have questions, don't hesitate to ask for more information.

-  COPYING says that most docs are in the public domain. Maybe that's not
-  clear enough, but on the other hand it looks a bit stupid to put
-  copyright information in tiny and relatively small docs like README.
- .
-  I don't dare to say that _all_ XZ Utils specific docs are in the public
-  domain unless otherwise mentioned in the file. I'm including PDF files
-  generated by groff + ps2pdf, and some day I might include Doxygen-
-  generated HTML docs too. Those don't include any copyright notices, but
-  it seems likely that groff + ps2pdf or at least Doxygen put some
-  copyrighted content into the generated files.

- changelog.gz (commit 975d8fd) explains:
- .
- Recreated the BCJ test files for x86 and SPARC. The old files
- were linked with crt*.o, which are copyrighted, and thus the
- old test files were not in the public domain as a whole. They
- are freely distributable though, but it is better to be careful
- and avoid including any copyrighted pieces in the test files.
- The new files are just compiled and assembled object files,
- and thus don't contain any copyrighted code.
