usage: $prg [<options>] host [path [path...]]
   or: $prg [<options>] \"host [host...]\" [path [path...]]
and options are the following:
       --download   Make local directory equal to the remote one
       --upload     Make remote directory equal to the local one
       --test       Simulate, don't actually change anything
       --dry-run    (Alias for --test)
       --force      Always copy whole files (disable rsync feature)
       --whole-file (Alias for --force)
    -v|--verbose    Verbose mode
       --host       Hostname(s) of remote host(s)
    -l|--localdir   Local base directory (only if path specified)
    -r|--remotedir  Remote base directory
    -p|--port       ssh port number
    -b|--batch      Enable BatchMode (for use in automatic scripts)
       --ssh-opts   Arbitrary ssh options
    -h|--help       This help text
    -*          Arbitrary rsync options

One of either --download or --upload is required. Last occurence
supersedes earlier ones.
If no path specified, current working directory is used."
