Dear fellow monks:

I have recently become interested in the concept of remote file differentials, similar to the network delta-encoding routines used by the fabulous rsync.

The idea is that you can create diffs between two files that are not necessarily in the same physical location, allowing you to synchronize only the differences between two files across a network.

rsync's methods have slowly been growing into their own library, librsync, which still seems fairly esoteric.

But as far as I know, these routines are just some sort of rolling-block checksum.

Has anybody done something similar with Perl? If not, what's the easiest way to create some sort of perl wrapper to these librsync functions?
