Really good logging
summary
Explains concrete setups: use levels (debug/info/warning/error/critical with numeric scores), attach multiple handlers (console, file, SMTPHandler emails tracebacks), formatters with timestamp/process/file/line, and use RotatingFileHandler with maxBytes and backupCount to cap temp logs. Shows code, config files, and dict-based logging, uses package_resources to ship configs, and wires sys.excepthook to log uncaught exceptions (or logging.exception with exc_info=True). Mentions Graylog2/GELF and syslog, and using logrotate to rotate on disk; examples all run and produce emails and rotated files.
