scrapy/scrapy/settings/default_settings.py

"""This module contains the default values for all settings used by Scrapy.

For more information about these settings you can read the settings
documentation in docs/topics/settings.rst

Scrapy developers, if you add a setting here remember to:

* add it in alphabetical order, with the exception that enabling flags and
  other high-level settings for a group should come first in their group
  and pairs like host/port and user/password should be in the usual order
* group similar settings without leaving blank lines
* add its documentation to the available settings documentation
  (docs/topics/settings.rst)
