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