# Production-configured Wagtail installation.
# BUT, SECURE SERVICES/ACCOUNT FOR FULL PRODUCTION USE!
# For a non-dummy email backend configure Django's EMAIL_BACKEND
# in settings/production.py post-installation.
# Tested on Debian 7.0.
# Tom Dyson and Neal Todd

# NB: Ensure the system locale is okay before running (dpkg-reconfigure locales).
