It is complicated, because it can do *much* more than just write to file: emailing logs, logging to HTTP, TCP, UDP, SOAP servers, logging to Unix syslog and NT's event log.

BTW typical Java solution: does scale up but not down. In 2.4, basicConfig() scales down

Tips, best practices

• use %r instead of %s or %d. if exceptions have been raised trying to log about an exception caused by incorrect data being passed in, e.g. string instead of a int. The repr form ensures that something sane will be logged
