def configure_logging(settings=None, install_root_handler=True):

Initialize logging defaults for Scrapy.

This function does:

Route warnings and twisted logging through Python standard logging
Assign DEBUG and ERROR level to Scrapy and Twisted loggers respectively
Route stdout to log if LOG_STDOUT setting is True

When install_root_handler is True (default), this function also creates a handler for the root logger according to given settings (see :ref:`topics-logging-settings`). You can override default options using settings argument. When settings is empty or None, defaults are used.

Parameters
settings:dict, `~scrapy.settings.Settings` object or `None`	settings used to create and configure a handler for the root logger (default: None).
install_root_handler:bool	whether to install root logging handler (default: True)
