      I do understand that. The code above was just an example. What I
do want is, different loggers for different areas of the application.
let me explain that.
      All the components in the system would have to log to syslog,
some components additionally would log to other places (like files).
So, for example:

core_app_logger = logger.getLogger('core')
sub_component_logger = logger.getLogger('core.sub_component')

core_app_logger.addHandler(logging.handler.SysLogHandler())
sub_component_logger.addHandler(logging.FileHandler('/tmp/sub_comp_log")

Now, because of the way logging is designed, any message sent to
sub_component would also get handled by the core-logger's handler
(SysLogHandler). ....or so it would seem ...I still haven't got the
SysLogHandler working :(


Regards
Steve
