- Files with the .z suffix have been compressed with the 'pack' program,
- which uses Huffman coding. They can be uncompressed with 'unpack',
- which replaces the compressed file with its uncompressed form. There is
- also the program 'pcat', which uncompresses .z files and sends the
- result to standard output.
-
- Files with the .Z suffix have been compressed with the 'compress'
- program, which uses the Lempel-Ziv compression method. They can be
- uncompressed with 'uncompress'. There is also a 'zcat' program, which
- is the analog of 'pcat' for these files.
-
- The 'pack' and 'compress' programs are generally available on Unix
- systems, and may be available on other systems, but I don't know which
- ones may have them.
