i thought it would, macos keeps the checksum in the resource fork.

actually the unsit utility is not included with the debian verison of
macutils it would seem, and i beleive i know why, i tried this utility
once and found it only works on 1.5.1 archives, this format was
apparently documented somewhat. stuffit 4 is proprietary and quite
UNdocumented, as is 5.0. unsit will not touch either. I had also
found that unsit pretty much only output corrupted files, its source
has not been modified since 1988, that is a very long time...
The best solution to .sit archives is to not use them, macbinary +
gzip provides a perfectly open and compatible solution.
