man : rdiff(1)
rdiff - compute and apply signature-based file differences
rdiff [options] signature old-file signature-file
rdiff [options] delta signature-file new-file delta-file
rdiff [options] patch basis-file delta-file new-file
In every case where a filename must be specified, - may be used instead
to mean either standard input or standard output as appropriate.
0 for successful completion, 1 for environmental problems (file not
found, invalid options, IO error, etc), 2 for a corrupt file and 3 for
an internal error or unhandled situation in librsync or rdiff.

The original rsync algorithm was discovered by Andrew Tridgell.
