rdiff - compute and apply signaturebased file differences
rdiff [options] signature oldfile signaturefile
rdiff [options] delta signaturefile newfile deltafile
rdiff [options] patch basisfile deltafile newfile
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 ideas in rdiff draw heavily on the work of Andrew Tridgell and Paulus Mackerras, the original developers of rsync.
rproxy/rdiff development has been supported in part by Linuxcare, Inc, a leading provider of enterprise services for open source software.
