docs: Configures a logger, according to the following rules:
  
      * With no options set, enables ``INFO`` level on stderr if stderr is a TTY;
        otherwise enables ``INFO`` level to Syslog.
  
      * With ``syslog=`` and/or ``stderr=``, configures as specified.
  
      * With ``level=``, enables either Syslog or stderr logging according to
        whether or not stderr is a TTY, but uses the level specified.
