+# For users with login '*test_user*', we don't want to store these documents in
+# the main users db. This is because we create and destroy a lot of test
+# users. This weirdness of using a different db for some users breaks a lot of
+# things, such as associations. However, this is OK for now since we don't need
+# those for running the frequent nagios tests.
+#
+# This module is included in user.rb. This will only work if it is included
+# after designs are defined, otherwise, the design definition will overwrite
+# find_by_login().
