Sorry about that, but zsync-0.2.0 had a paper-bag bug. It would go into an infinite loop when more than one local source file was supplied. This is now fixed; in fact I have taken the chance to clean up the hashing code a little.

I have also improved compressed stream support; zsync now has the beginnings of support for gzip files containing stored blocks. These typically occur when compressing binary or other files that contain sections that do not compress well. Without supporting these, I can't really claim that zsync can transfer gzip files — at the moment, it just happens to work on must compressed text files. There is more work to do, but this is the first 90% that takes 10% of the work, and it brings us closer at least.
