Features higher compression ratios and better performance thanks to a order-0 context mixing entropy coder, a fast Burrows-Wheeler transform code making use of suffix arrays and a RLE with Lempel Ziv+Prediction pass based on LZ77-style string matching and PPM-style context modeling.\n\nLike its ancestor, **BZip3 excels at compressing text or code**.\n\n## Installation\n\n```console\n# If using a git clone (not needed for source packages), first...\n$ ./bootstrap.sh\n\n# All...\n$ ./configure\n$ make\n$ sudo make install\n```\n\nAlternatively, you might be able to install bzip3 using your system\u0027s package manager:\n\n[![Packaging status](https://repology.org/badge/vertical-allrepos/bzip3.svg?columns=3)](https://repology.org/project/bzip3/versions)\n\nOn macOS, you can use [Homebrew](https://brew.sh) to easily install:\n\n```console\n$ brew install bzip3\n```\n\n## Perl source code benchmark\n\nFirst, I have downloaded every version of Perl5 ever released and decompressed them.\n\n```bash\n% wget -r -l1 -nH --cut-dirs=2 --no-parent -A.tar.gz --no-directories https://www.cpan.org/src/5.0/\n% for g in *.gz; do gunzip $g; done\n% ls -la | wc -l\n262\n```\n\nThen, I put all the resulting `.tar` files in a single `.tar` file and tried to compress it using various compressors:\n\n```\nxz -T16 -9 -k all.tar  10829.91s user 26.91s system 1488% cpu 14658M memory 12:09.24 total\nbzip2 -9 -k all.tar  981.78s user 9.77s system 95% cpu 8M memory 17:16.64 total\nbzip3 -e -b 256 -j 12 all.tar  2713.81s user 16.28s system 634% cpu 18301M memory 7:10.10 total\nbzip3 -e -b 511 -j 4 all.tar  17.65s user 12.19s system 170% cpu 12178M memory 7:08.65 total\nzstd -T12 -16 all.tar  4162.94s user 16.40s system 1056% cpu 687M memory 6:35.62 total\n```\n\nThe results follow:\n\n| Method           | Compressed size (bytes) |\n| -----",
