+This module contains common configuration settings for Django libraries.
+
+Most of our CA code uses at least the Django ORM; the web interface
+uses a lot more of Django.  We also want to handle all normal user
+configuration via rpki.conf, so some of the code here is just pulling
+settings from rpki.conf and stuffing them into the form Django wants.

+# debugging enabled in the GUI doesn't mean we want it in irdb.

+# If you must enable debugging, you may need to add code that uses
+# django.db.reset_queries() to clear the query list manually, but it's
+# probably better just to run with debugging disabled, since that's
