o ARC also performs Huffman Squeezing on data. The Huffman Squeeze algorithm was removed from MSDOS 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.
o Compresses and extracts Squashed files. "Squashing" was created by Phil Katz in his PKxxx series of ARC utility programs for MSDOS. Dan Lanciani wrote the original modifications to ARC's Crunch code to handle Squashing. I've 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.
Notes for ARC 5.21e October 31, 1991 ARC 5.21 for Unix is currently at patch level 6. The code provided here has been used on 4.3 BSD based Unix systems and on the Atari ST. (The GNU C compiler, version 1.40, was used to make the ST version. It should still compile with Mark Williams C, but I haven't bothered to try it.) The current version is over twice as fast as previous releases, for all more»
