/* ARC - Archive utility
Version 5.21, created on 04/22/87 at 15:05:21
(C) COPYRIGHT 1985-87 by System Enhancement Associates; ALL RIGHTS RESERVED
By: Thom Henderson
Description:
This program is a general archive utility, and is used to maintain
an archive of files. An "archive" is a single file that combines
many files, reducing storage space and allowing multiple files to
be handled as one.
Instructions:
Run this program with no arguments for complete instructions.
Programming notes:
ARC Version 2 differs from version 1 in that archive entries
are automatically compressed when they are added to the archive,
making a separate compression step unecessary. The nature of the
compression is indicated by the header version number placed in
each archive entry, as follows:
1 = Old style, no compression
2 = New style, no compression
3 = Compression of repeated characters only
4 = Compression of repeated characters plus Huffman SQueezing
5 = Lempel-Zev packing of repeated strings (old style)
6 = Lempel-Zev packing of repeated strings (new style)
7 = Lempel-Zev Williams packing with improved hash function
8 = Dynamic Lempel-Zev packing with adaptive reset
9 = Dynamic Lempel-Zev packing, larger hash table
Type 5, Lempel-Zev packing, was added as of version 4.0
Type 6 is Lempel-Zev packing where runs of repeated characters
have been collapsed, and was added as of version 4.1
Type 7 is a variation of Lempel-Zev using a different hash
function which yields speed improvements of 20-25%, and was
added as of version 4.6
Type 8 is a different implementation of Lempel-Zev, using a
variable code size and an adaptive block reset, and was added
as of version 5.0
Type 9 is a slight modification of type 8, first used by Phil
Katz in his PKARC utilites. The primary difference is the use
of a hash table twice as large as for type 8, and that this
algorithm called Squashing, doesn't perform run-length encoding
on the input data.
Verion 4.3 introduced a temporary file for holding the result
of the first crunch pass, thus speeding up crunching.
Version 4.4 introduced the ARCTEMP environment string, so that
the temporary crunch file may be placed on a ramdisk. Also
added was the distinction bewteen Adding a file in all cases,
and Updating a file only if the disk file is newer than the
corresponding archive entry.
The compression method to use is determined when the file is
added, based on whichever method yields the smallest result.
