The goal here is to build a file server over http that clients can pull patches from to stay in sync with the servers' files.

Inspired by zsync.

To use, run make-test-files.sh and then load Hsync.hs into ghci.

You can then fake-o patch one file to another with,

patch "test/abc" "test/abc2"

This will show information about the files, their similarities (lcs) and the generated patch (list).
