Anyone know of a good free patch creator?

Does anyone know of a good patching program that is free? You know, one that can take a directory with your old program in it and compare it to a directory with your new version, and spit out a patch that is only the difference between the two?

Also, I am looking for something that can patch the entire directory, not just one exe.

bsdiff is easily the best solution for binary patching. Unfortunately, it's just a binary and doesn't offer anything for actually creating an installer or patcher.
