PackageDescription | archive utility based on the MS-DOS ARC program
This program is based on the MS-DOS ARC program, version 5.21, plus a few
enhancements.
.
ARC also performs Huffman Squeezing on data. The Huffman Squeeze algorithm
was removed from MS-DOS ARC after version 5.12. It turns out to be more
efficient than Lempel-Ziv style compression when compressing graphic images.
Squeeze analysis is always done now, and the best of packing, squeezing,
or crunching is used.
.
Compresses and extracts Squashed files. "Squashing" was created by
Phil Katz in his PKxxx series of ARC utility programs for MS-DOS.
Dan Lanciani wrote the original modifications to ARC's Crunch code to
handle Squashing. Klaus Reimer made minor changes since then, mostly to
reduce the amount of memory required. The 'q' option flag must be
specified to Squash files. The Squashing algorithm will be used instead
of the usual Crunch algorithm, and will be compared against packing and
squeezing, as before.
.
This package provides the arc and marc commands. MARC can be used to merge
files compressed by ARC. |
