I'll look for it.

I didn't find anything there, but the hard part of it is handled by
Archive::Zip.  I suspect that if I have to create Archive::Jar myself,
I can probably subclass Archive::Zip.

Okay.

My C++ is even worse than my C, which is abysmal enough that I don't
try to use it for anything as nontrivial as handling non-text file
formats.  I can pass for fluent in Perl, elisp, and Inform (and a
small handful of markup languages), and I also know a little Scheme,
and if I draw on distant memories several dialects of BASIC and some
Pascal and a little 8086 assembly language, and I've had just enough
exposure to Python, PHP, and JavaScript to be able to follow the jist
of something, but I know precious little C or C++, really only just
barely enough to cause trouble[1].

If there were a spec, I could probably just write a Perl class for it
as a wrapper around Archive::Zip.

[1] If C code that I download doesn't come with a configure script, I
    have to read the gcc manpage to remind myself how to compile it.
    I can make small changes like commenting out an unwanted if test
    (such as the one in civclient that prevents it from running as
    root, though I no longer bother changing that now that I've
    discovered gdmflexiserver), but much beyond that is a stretch.
