2574 Creates a new log object, optionally you can specify a filename here to
2575 indicate the file to log to. If no log file is specified, you can specify one

2579 Until one of these methods is called, all log calls will buffer messages ready

2603 If successful, all buffered data is written out to the file, and any further
2604 logging is written directly to the file.
