Okay, thanks for the suggestions. I think I'll try Zlib first (it's part of the standard Ruby library) and maybe move onto InfoZip if that doesn't work.
One thing I'm not clear on is how many Zip specifications there are? I had thought that any Zip implementation would produce identical Zip files, but as I've said, rubyzip and zipruby didn't.
How can you tell whether an implementation will churn out the right type of file?
