- Yes, (unfortunately for the name) there is. You're undoubtedly using the
- original Unix compact program, which predates compress and uses a dynamic
- huffman compression scheme. However, in about December 1990, Gene Olsen
- submitted a program named compact to either comp.sources.misc or
- comp.source.unix (I don't remember which). According to the man pages, it
- uses a modified LZW compression not unlike that of V.42bis and is ideally
- suited to larger (> 1MB) files. This is undoubtedly the one Bill used.

- Hope this helps (and that it's right :-) ).
