+       This option may be given multiple times. The given argument is
+       passed verbatim to the rsync command. Note that in order to use
+       rsync options that require an argument, you have to specify the
+       option and its argument as separate --rsync-options, like this:
+
+               --rsync-option --exclude --rsync-option /proc
