.I signature_file

or

.I delta_file

are "-", the data will be read from stdin or written to stdout as appropriate.

.SH DESCRIPTION

.B rdiffdir

is supposed to be like rdiff, but can operate on directories.  See

.BR rdiff (1)

for more information.  The syntax is similar.

.SH OPTIONS

.TP

.BI "--write-sig-to " sigfile

This option is only used in

.B delta

and

.B tar

modes.  When specified, rdiffdir will write a signature of the

directory it is processing to sigfile.  The end result will be a delta

and a new signature calculated over the

.B same

data.

.TP

.B -z, --gzip-compress

Enable gzip compression and decompression of signature and delta

files.

.SH SELECTION OPTIONS

In

.B signature

and

.B delta

modes, rdiffdir accepts

.BR duplicity -like

selection options including --exclude, --exclude-filelist-stdin, etc.

See the

.BR duplicity (1)

manual page for more information.

.SH BUGS

Hard links are currently unsupported (they will be treated as

non-linked regular files).

Bad signatures will be treated as empty instead of logging appropriate

error message.
