    "Rsync is a fast and versatile file copying tool.  It can copy locally,
to/from another host over any remote shell, or to/from a remote rsync daemon.
Its delta-transfer algorithm reduces the amount of data sent over the network
by sending only the differences between the source files and the existing
files in the destination.")

remote-delta algorithm.  This algorithm allows efficient remote updates of a
file, without requiring the old and new versions to both be present at the
sending end.  The library uses a \"streaming\" design similar to that of zlib
with the aim of allowing it to be embedded into many different applications.")
