Key features of this formatter are: • Color support when logging to a terminal that supports it. • Timestamps on every log line. • Robust against tornado.options. parse_config_file (unless --logging=none is used). Color support on Windows versions that do not support ANSI color codes is enabled by use of the colorama library. Applications that wish
