config = <onetick.py.configuration.Config object>#

This object is used to access onetick.py configuration options.

Configuration options may be changed by modifying properties of this object or by setting environment variables. Also, configuration options may be accessed via config.['...'] syntax, e.g. config['tz']

The following is the order of priority of configuration values:
