+dit(bf(--write-batch=FILE)) Record a file that can later be applied to
+another identical destination with --read-batch. See the "BATCH MODE"
+section for details.
+
+dit(bf(--read-batch=FILE)) Apply all of the changes stored in FILE, a
+file previously generated by --write-batch.
+If em(FILE) is "-" the batch data will be read from standard input.
+See the "BATCH MODE" section for details.
+
+dit(bf(-4, --ipv4) or bf(-6, --ipv6)) Tells rsync to prefer IPv4/IPv6
+when creating sockets. This only affects sockets that rsync has direct
+control over, such as the outgoing socket when directly contacting an
+rsync daemon. See also these options in the --daemon mode section.
+
+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(). 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.
+
+enddit()
+
+The options allowed when starting an rsync daemon are as follows:
+
+startdit()
+
+dit(bf(--daemon)) This tells rsync that it is to run as a daemon. The
+daemon may be accessed using the bf(host::module) or
+bf(rsync://host/module/) syntax.
+
+If standard input is a socket then rsync will assume that it is being
+run via inetd, otherwise it will detach from the current terminal and
+become a background daemon. The daemon will read the config file
+(rsyncd.conf) on each connect made by a client and respond to
+requests accordingly. See the rsyncd.conf(5) man page for more
+details.
+
+dit(bf(--address)) By default rsync will bind to the wildcard address
+when run as a daemon with the --daemon option or when connecting to a
+rsync server. The --address option allows you to specify a specific IP
+address (or hostname) to bind to. This makes virtual hosting possible
+in conjunction with the --config option. See also the "address" global
+option in the rsyncd.conf manpage.
+
+dit(bf(--bwlimit=KBPS)) This option allows you to specify a maximum
+transfer rate in kilobytes per second for the data the daemon sends.
+The client can still specify a smaller --bwlimit value, but their
+requested value will be rounded down if they try to exceed it. See the
+client version of this option (above) for some extra details.
+
+dit(bf(--config=FILE)) This specifies an alternate config file than
+the default. This is only relevant when --daemon is specified.
+The default is /etc/rsyncd.conf unless the daemon is running over
+a remote shell program and the remote user is not root; in that case
+the default is rsyncd.conf in the current directory (typically $HOME).
+
+dit(bf(--no-detach)) When running as a daemon, this option instructs
+rsync to not detach itself and become a background process. This
+option is required when running as a service on Cygwin, and may also
+be useful when rsync is supervised by a program such as
+bf(daemontools) or AIX's bf(System Resource Controller).
+bf(--no-detach) is also recommended when rsync is run under a
+debugger. This option has no effect if rsync is run from inetd or
+sshd.
