+// dbSetup.js

+// Script for initial Sentinel MongoDB database setup.
+//
+// This script creates the required indices and a mock development user.
+//
+// The script must be run by an existing MongoDB user that can create
+// databases and add users. Since this is part of an Ansible deployment,
+// you are *strongly* recommended to keep this script idempotent.
+//
+// Usage: mongo {address}:{port} dbSetup.js
