The brownie package is the main package containing all of Brownie's functionality.
>>> from brownie import *
>>> dir()

The _config module handles all Brownie configuration settings. It is not designed to be accessed directly. If you wish to view or modify config settings while Brownie is running, import brownie.config which will return a ConfigDict <brownie._config.ConfigDict> with the active settings:
>>> from brownie import config
>>> type(config)
<class 'brownie._config.ConfigDict'>
>>> config['network_defaults']
{'name': 'development', 'gas_limit': False, 'gas_price': False}Internal metaclass used to create singleton objects. Instantiating a class derived from this metaclass will always return the same instance, regardless of how the child class was imported.
