Zoo versions 2 greater can extract files from either a self-extracting
archive made with sez or from a corrupted archive.  This is done with
the help of a program called fiz which reads teh archive and lists
probable offsets into the archive at which various files reside. You then
run zoo with with the '@n extract/list at position n' option.  If you
ain't got that option available then I suggest you upgrade zoo.  If you
do then look through the files that came with the distribution for the
fiz program. Of course the above instructions are only applicable if
you're interested in getting at self extracting zoo files.  I haven't
seen too many on the net - it seems that they're of less importance
since the virus wars have begun.
