-# Using logging in multiple modules
-
-Multiple calls to `logging.getLogger('someLogger')` return a reference to the
-same logger object. This is true not only within the same module, but also
-across modules as long as it is in the same Python interpreter process. It is
-true for references to the same object; additionally, application code can
-define and configure a parent logger in one module and create (but not
-configure) a child logger in a separate module, and all logger calls to the
-child will pass up to the parent. Here is a main module:
-
-``javascript
-import * as logging from 'eslib/logging';
-import * as my_module from './my_module';
-
-// create logger with 'spam_application'
-var logger = logging.getLogger('spam_application');
-logger.setLevel(logging.DEBUG);
-
-// create file handler which logs even debug messages
-var fh = logging.FileHandler('spam.log')
-fh.setLevel(logging.DEBUG);
-
-// create console handler with a higher log level
-var ch = logging.StreamHandler();
-ch.setLevel(logging.ERROR);
-
-// create formatter and add it to the handlers
-var formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s');
-fh.setFormatter(formatter);
-ch.setFormatter(formatter);
-
-// add the handlers to the logger
-logger.addHandler(fh);
-logger.addHandler(ch);
-
-logger.info('creating an instance of auxiliary_module.Auxiliary')
-```
