- This is an MS-DOS combined implementation of the un*x tar(1) and
- compress(1) programs. It creates P1003 "Unix Standard" [draft 6]
- tapes by default, and can optionaly compress and decompress files
- compatible with the un*x compress(1) program using up to 16 bits
- compression without intermediate files. Filename characters that
- are not supported by most MS-DOS shells (;=+<>|,*?:[]\ ) are silently
- converted into a circumflex (^) character. Filanemes longer than
- the ones supported by MS-DOS are silently truncated and can thus
- overwrite files named with the same initial characters.
-
- The main advantage of this program is the standard format
- of the files it deals with. The programs and file formats
- for compress and tar are widely available and files can
- be transfered directly to / from most un*x boxes.
- The compression ratio achieved by the program is usually better
- than any of the other archivers (arc, zoo, pkarc, gsarc) and
- the speed is respectable. One problem of it, is that it is memory
- hungry. It needs around 480k to run because of the 16 bit compress.
-
- The tar engine of the program is pdtar written by John Gilmore
- (gnu@toad.com) and was only slightly modified to fix some bugs
- and read / write compressed files on MS-DOS. In the README
- file of the pdtar distribution is the following list of thanks:
-
- This program is much better than it started, due to
- the effort and care put in by Henry Spencer, Fred Fish,
- Ian Darwin, Geoff Collyer, Stan Barber, Guy Harris,
- Dave Brower, Richard Todd, Michael Rendell, Stu Heiss,
- and Rich $alz. Thank you, one and all.
-
- The compression is based on the un*x compress program version 4.0.
- Many changes have been made to allow it to cooperate with tar,
- to improve its speed and to handle 16 bit compression efficiently
- on Intel architectures.
-
- The compress program was written and improved by Spencer W. Thomas,
- Jim McKie, Steve Davies, Ken Turkowski, James A. Woods and Joe Orost.
-
- I would like to thank all the people above for making this
- program possible.
