unsit - extract/list files in a Macintosh Stuffit archive file

For the Stuffit archive file listed, extracts the files in the archive
into separate files. This makes it possible, for example, to separate a
large StuffIt file into component files for selective downloading,
rather than downloading the larger archive file just to extract a
single, small file. It also allows the use of StuffIt to compress a
group of files into a single, smaller archive that can be uploaded to a
Unix system for storage, printing, etc.

In the normal mode, both the data and the resource forks of the
component Macintosh files in the archive are extracted and stored in
Unix files with the extension .dat and .rsr appended to the end of the
Macintosh file name. In addition, a .inf file will be created with the
Finder information. These three file are compatible with the macput
program for downloading to a Mac running Macterminal. If only the data
or resource fork is extracted, no addition extension is appended to the
Mac file name. Characters in the Mac file name that are illegal (or
unwieldy, like spaces) are changed to underscores in the Unix file
name. The true Mac file name is retained in the .inf file and is
restored when the file is downloaded.

StuffIt version 1.5 has the ability to archive a group of files and
folders in such a way that the hierarchical relationship of the files
and folders is maintained. Unsit version 1.5 can unpack files archived
in this manner and place them in corresponding subdirectories so as to
maintain the hierarchy. As an option, the hierarcy can be flattened
out and all the files stored in the current directory.

The options are similar to those for macput and unpit.

-f
For StuffIt files containing a "Hierarchy Maintained Folder" entry,
extract the files into a "flat" organization (all in the current
directory) rather than maintaining the hierarchy by creating new
directories, etc. Default is to maintain the hierarchical folder
organization.

-l (el, not a number 1)
List the files in the archive but do not
extract them. The name, size, type, and creator of each file is
listed.

-m
Assumes the input file in MacBinary format rather than macput/macget
format and skips over the MacBinary header.

-r
Extract resources forks only.

-d
Extract data forks only.

-u
Extract data fork and change into a Unix text file. This only works
if the file is really a text file.

-q
Query user before extracting files and folders. If a "n" answer is given for
a folder, none of the files or folders in that folder will be extracted.

-v
Verbose option. Causes unsit to list name, size, type, and creator
of each file extracted.

BUGS
----
Files that were compressed by StuffIt with the Lempel-Ziv method and
are extracted with the -u switch (text files) are not checked for a
correct CRC value when .I unsit uncompresses them. This is because
unsit pipes the data through compress and tr to extract the file and
never has a chance to do the CRC check.

The compress program has been observed to go into strange states when
uncompressing a damaged file. Often it will get stuck writing out
bogus data until the disk fills up. Since unsit sends data through
compress, the same problem could occur when extracting files from a
damaged Stuffit archive.

For archives that have been compressed with the Lempel-Ziv method, the
compress program must be present on the system and in the search path
since unsit uses it for the uncompressing. Compress is available from
the comp.sources.unix archives.
