+

++dit(bf(--chown=USER:GROUP)) This option forces all files to be owned by USER
++with group GROUP. This is a simpler interface than using bf(--usermap) and
++bf(--groupmap) directly, but it is implemented using those options internally,
++so you cannot mix them. If either the USER or GROUP is empty, no mapping for
++the omitted user/group will occur. If GROUP is empty, the trailing colon may
++be omitted, but if USER is empty, a leading colon must be supplied.
++
++If you specify "--chown=foo:bar, this is exactly the same as specifying
++"--usermap=*:foo --groupmap=*:bar", only easier.

dit(bf(--timeout=TIMEOUT)) This option allows you to set a maximum I/O
timeout in seconds. If no data is transferred for the specified time
then rsync will exit. The default is 0, which means no timeout.
