  def caveats; <<-EOS.undent
    iftop requires superuser privileges. You can either run the program
    via `sudo`, or change its ownership to root and set the setuid bit:
    $ sudo chown root:wheel #{sbin}/iftop
    $ sudo chmod u+s #{sbin}/iftop

    In any case, you should be certain that you trust the software you
    are executing with elevated privileges.
