There's not much I can do for you. You might want to see if the zlib code can help you. gzip is a format that can only compress one file. It has a very small header that doesn't even contain a filename. zlib can easily be used with the gzip format if you write some code to deal with that small header. I'm not=20 sure about what's there, but it seems like it should be trivial.
