########################################################################
# Here's how settings for the Zulip project work:
#
# * settings.py contains non-site-specific and settings configuration
# for the Zulip Django app.
# * settings.py imports prod_settings.py, and any site-specific configuration
# belongs there.  The template for prod_settings.py is prod_settings_template.py
#
# See http://zulip.readthedocs.io/en/latest/settings.html for more information
