[ excerpt from developer's web site with modifications ]
Sometimes, when you run 2 different .ZIP programs on the same data
(PKZIP & KZIP for example), some files get compressed better in one
program, while other files get compressed better in the other.
ZIPMIX will take the best files from each one and create a new
output file, which is guaranteed to be equal to or smaller in size
to both of the input files.
ZIPMIX can also be used to perform boolean operations on ZIP files,
such as merging 2 ZIP files together, or updating a new file (with
some tricks).
