  -user <string>
    	your pool username from https://cryptonote.social/xmr (default "donate-getmonero-org")
  -saver=<bool>
    	mine only when screen is locked (default true)
  -exclude <string>
        pause mining during the specified hours. Format is XX-YY where XX and YY are hours of
        the day designated in 24 hour time. For example, -exclude=11-16 will pause mining betwen
        11:00am and 4:00pm. This can be used, for example, to pause mining during times of high
        machine usage or high electricity rates.
  -threads <int>
    	number of threads (default 1)
  -rigid <string>
    	your rig id (default "csminer")
  -tls <bool>
       whether to use TLS when connecting to the pool (default false)
  -config <string>
        advanced pool config option string, for specifying starting diff, donation percentage,
        email address for notifications, and more. See "advanced configuration options" under Get
        Started on the pool site for details. Some options will require you to also specify your
        wallet id (see below) in order to be changed.
  -wallet <string>
        your wallet id. You only need to specify this when establishing a new username, or if
        specifying a 'secure' config parameter change such as a new pool donation amount or email
        address. New usernames will be established upon submitting at least one valid share.
