%description
    The librsync library implements network delta-compression of
    streams and files. The algorithm is similar to that used in the
    rsync(1) and xdelta(2) programs, but specialized for transfer of
    arbitrary-length octet streams. Unlike most diff programs, librsync
    does not require access to both of the files on the same machine,
    but rather only a short "signature" of the old file and the
    complete contents of the new file.
