[Unix] When used without a qualifier, generally refers to {crunch}ing
of a file using a particular C implementation of compression by
Joseph M. Orost et al.: and widely circulated via {Usenet}; use of
{crunch} itself in this sense is rare among Unix hackers.
Specifically, compress is built around the Lempel-Ziv-Welch algorithm
as described in "A Technique for High Performance Data Compression",
Terry A. Welch, IEEE Computer, vol. 17, no. 6 (June 1984), pp. 8--19.
