``-h, --help``
      Show the help message and exit

``--version``
      Print the version number and exit

``-v, --verbose``
      Print more verbose output

``--noverbose``
      Disable verbose output

``-d, --debug``
      Print debugging output (set logging level to DEBUG instead of
      default WARNING level)

``--nodebug``
      Disable debugging output

``--use-syslog``
      Use syslog for logging

``--nouse-syslog``
      Disable the use of syslog for logging

``--syslog-log-facility SYSLOG_LOG_FACILITY``
      syslog facility to receive log lines

``--config-dir DIR``
      Path to a config directory to pull \*.conf files from. This
      file set is sorted, to provide a predictable parse order
      if individual options are over-ridden. The set is parsed after
      the file(s) specified via previous --config-file, arguments hence
      over-ridden options in the directory take precedence. This means
      that configuration from files in a specified config-dir will
      always take precedence over configuration from files specified
      by --config-file, regardless to argument order.

``--config-file PATH``
      Path to a config file to use. Multiple config files can be
      specified by using this flag multiple times, for example,
      --config-file <file1> --config-file <file2>. Values in latter
      files take precedence.

``--log-config-append PATH`` ``--log-config PATH``
      The name of logging configuration file. It does not
      disable existing loggers, but just appends specified
      logging configuration to any other existing logging
      options. Please see the Python logging module documentation
      for details on logging configuration files. The log-config
      name for this option is deprecated.

``--log-format FORMAT``
      A logging.Formatter log message format string which may use any
      of the available logging.LogRecord attributes. Default: None

``--log-date-format DATE_FORMAT``
      Format string for %(asctime)s in log records. Default: None

``--log-file PATH, --logfile PATH``
      (Optional) Name of log file to output to. If not set, logging
      will go to stdout.

``--log-dir LOG_DIR, --logdir LOG_DIR``
      (Optional) The directory to keep log files in (will be prepended
      to --log-file)
