    <p>
      PulseAudio provides a simple command line language used by configuration
      scripts and the pacmd interactive shell, and the modules module-cli and
      module-cli-protocol-{unix,tcp}. Empty lines and lines beginning with a
      hashmark (#) are silently ignored. Several commands are supported.
    </p>

    <p>
      Note that any boolean arguments can be given positively as '1', 'on' or any
      word starting with the letters 't' or 'y'. Likewise, negative values can be
      given as '0', 'off' or any word starting with the letters 'f' or 'n'.
      Case is ignored.
