+rsync client logs to stdout on a per-file basis. This format can be used
+without bf(--verbose) to enable just the outputting of the file-transfer
+information, or it can be used to change how the names are output when
+bf(--verbose) is enabled. Rsync will log the name of an item prior to its
+transfer unless one of the transferred-byte-count values is requested, in
+which case the logging is done at the end of the item's transfer. In this
+late-transfer state, if bf(--progress) is also specified, rsync will output
+just the name of the file prior to the progress information.
+
+The log format is specified using the same format conventions as the
+"log format" option in rsyncd.conf, so see that manpage for details.
+(Note that this option does not affect what a daemon logs to its logfile.)
