PHP-Bindings for librsync

This php extension provides a binding to the librsync C-library. This library is a open-source implementation of the rsync remote-delta algorithm.

This algorithm is using a rolling check-sum and a md4 check-sum for blocks of the file to generate a signature file. The signature file is used to generate a diff from the file on the remote site. This diff can be used on the local site to patch the file.
