		unsit - Macintosh StuffIt file extractor

			Version 1, for StuffIt 1.31

This program will unpack a Macintosh StuffIt file into separate files.
The data fork of a StuffIt file contains both the data and resource
forks of the packed files.  The program will unpack each Mac file into
separate .data, .rsrc., and .info files that can be downloaded to a
Mac using macput.  The program is much like the "unpit" program for
breaking apart Packit archive files.

			***** IMPORTANT *****
To extract StuffIt files that have been compressed with the Lempel-Ziv
compression method, unsit pipes the data through the "compress"
program with the appropriate switches, rather than incorporate the
uncompression routines within "unsit".  Therefore, it is necessary to
have the "compress" program on the system and in the search path to
make "unsit" work.  "Compress" is available from the comp.sources.unix
archives.

The program syntax is much like unpit and macput/macget, with some added
options:

	unsit [-rdulvq] stuffit-file.data

The -r and -d flags will cause only the resource and data forks to be
written.  The -u flag will cause only the data fork to be written and
to have carriage return characters changed to Unix newline characters.
The -l flag will make the program only list the files in the StuffIt
file.  The -v flag causes the program to list the names, sizes, type,
and creators of the files it is writing.  The -q flag causes it to
list the name, type and size of each file and wait for a 'y' or 'n'
for either writing that file or skipping it, respectively.

Some of the program is borrowed from the macput.c/macget.c programs.
Many, many thanks to Raymond Lau, the author of StuffIt, for including 
information on the format of the StuffIt archives in the documentation.
