a high performance, general purpose data compressor written in the crab-lang
orz is an optimized ROLZ (reduced offset Lempel-Ziv) general purpose data compressor. input data is encoded as ROLZ-matches (reduced-offsets and match lengths), 2-byte words, and single bytes. then all encoded symbols are processed with a symbol ranking (aka Move-to-Front) transformer and a static huffman coder. Benefited from the ROLZ algorithm, orz compresses times faster than many other LZ-based compressors which has same compression ratio, and decompression speed is still very acceptable.

To install orz, run the following command in macOS terminal (Applications->Utilities->Terminal)
sudo port install orz
To see what files were installed by orz, run:
port contents orz
To later upgrade orz, run:
sudo port selfupdate && sudo port upgrade orz
