++dit(bf(--checksum-seed=NUM)) Set the MD4 checksum seed to the integer
++NUM. This 4 byte checksum seed is included in each block and file
++MD4 checksum calculation. By default the checksum seed is generated
++by the server and defaults to the current time(), or 32761 if
++bf(--write-batch) or bf(--read-batch) are specified. This option
++is used to set a specific checksum seed, which is useful for
++applications that want repeatable block and file checksums, or
++in the case where the user wants a more random checksum seed.
++Note that setting NUM to 0 causes rsync to use the default of time()
++for checksum seed. Note also that --write-batch and --read-batch
++set the checksum seed to 32761, so --checksum-seed=NUM needs to
++follow these options if you want to specify a different checksum
++seed in batch mode.
