A Program for Compressing Files
The xz command is a very powerful program for compressing files.
* Average compression ratio of LZMA is about 30% better than that of
gzip, and 15% better than that of bzip2.
* Decompression speed is only little slower than that of gzip, being
two to five times faster than bzip2.
* In fast mode, compresses faster than bzip2 with a comparable
compression ratio.
* Achieving the best compression ratios takes four to even twelve
times longer than with bzip2. However. this doesn't affect
decompressing speed.
* Very similar command line interface to what gzip and bzip2 have.

- update to 5.6.0:
* This bumps the minor version of liblzma because new
features were added. The API and ABI are still backward
compatible with liblzma 5.4.x and 5.2.x and 5.0.x.
* liblzma:
- Disabled the branchless C variant in the LZMA
decoder based on the benchmark results from the community.
- Disabled x86-64 inline assembly on x32 to fix the
build.
* Sandboxing support in xz:
- Landlock is now used even when xz needs to create
files.
- Landlock and pledge(2) are now stricter when
reading from more than one input file and only writing to
standard output.
- Added support for Landlock ABI version 4.
- Now builds lzmainfo and lzmadec.
- xzdiff, xzgrep, xzless, xzmore, and their symlinks
are now installed. The scripts are also tested during "make
test".
- Added translation support for xz, lzmainfo, and the
man pages.
- Minimum required CMake version is now 3.14.
* liblzma:
- LZMA decoder: Speed optimizations to the C code and
added GCC & Clang compatible inline assembly for
x86-64.
- Added lzma_mt_block_size() to recommend a Block
size for multithreaded encoding.
- Added CLMUL-based CRC32 on x86-64 and E2K with
