:compress: [UNIX] vt. When used without a qualifier, generally
refers to {crunch}ing of a file using a particular
C implementation of compression by James A. Woods 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.
