Authors of XZ Utils
===================
XZ Utils is developed and maintained by
Lasse Collin <[email protected]>.
Major parts of liblzma are based on code written by Igor Pavlov,
specifically the LZMA SDK <https://7-zip.org/sdk.html>. Without
this code, XZ Utils wouldn't exist.
The SHA-256 implementation in liblzma is based on code written by
Wei Dai in Crypto++ Library <https://www.cryptopp.com/>.
A few scripts have been adapted from GNU gzip. The original
versions were written by Jean-loup Gailly, Charles Levert, and
Paul Eggert. Andrew Dudman helped adapting the scripts and their
man pages for XZ Utils.
The initial version of the threaded .xz decompressor was written
by Sebastian Andrzej Siewior.
The initial version of the .lz (lzip) decoder was written
by Michał Górny.
Architecture-specific CRC optimizations were contributed by
Ilya Kurdyukov, Hans Jansen, and Chenxi Mao.

Special author: Jia Tan was a co-maintainer in 2022-2024. He and
the team behind him inserted a backdoor (CVE-2024-3094) into
XZ Utils 5.6.0 and 5.6.1 releases. He suddenly disappeared when
this was discovered.
Many people have contributed improvements or reported bugs.
Most of these people are mentioned in the file THANKS.
The translations of the command line tools and man pages have been
contributed by many people via the Translation Project:
- https://translationproject.org/domain/xz.html
- https://translationproject.org/domain/xz-man.html
The authors of the translated man pages are in the header comments
of the man page files. In the source package, the authors of the
translations are in po/*.po and po4a/*.po files.
