net/librsync 2.3.4 DragonFly

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.
