-log Selects the log file mode:
     0: disabled - no log file will be written
     1: write log file but don't show debug messages on screen (default)
     2: write log file and show debug messages on screen
  -logfile Set the name of the logfile. If you place an asterisk (*) in the logfile name, it will be
      replaced by the current date/time to create a unique name every time PhoenixMiner is started. If there
      is no asterisk in the logfile name, the new log entries will be added to end of the same file. If you
      want to use the same logfile but the contents to be overwritten every time when you start the miner,
      put a dollar sign ($) character in the logfile name (e.g. -logfile my_log.txt$).
  -logdir
