dit(bf(-q, --quiet)) This option decreases the amount of information you

the destination machine as an additional hierarchy to compare destination
files against doing transfers (if the files are missing in the destination
dit(bf(--no-blocking-io)) Turn off bf(--blocking-io), for use when it is the
