       set ``LANGUAGES`` to a list of languages. For example::
 
           LANGUAGES = (
-            ('de', _('German')),
-            ('en', _('English')),
+            ('de', 'German'),
+            ('en', 'English'),
           )
 
       This example restricts languages that are available for automatic
       selection to German and English (and any sublanguage, like de-ch or
       en-us).
 
-    * If you define a custom ``LANGUAGES`` setting, as explained in the
-      previous bullet, it's OK to mark the languages as translation strings
-      -- but use a "dummy" ``ugettext()`` function, not the one in
-      ``django.utils.translation``. You should *never* import
-      ``django.utils.translation`` from within your settings file, because that
-      module in itself depends on the settings, and that would cause a circular
-      import.
-
-      The solution is to use a "dummy" ``ugettext()`` function. Here's a sample
-      settings file::
-
-          ugettext = lambda s: s
-
-          LANGUAGES = (
-              ('de', ugettext('German')),
-              ('en', ugettext('English')),
-          )
-
-      With this arrangement, ``django-admin.py makemessages`` will still find
-      and mark these strings for translation, but the translation won't happen
-      at runtime -- so you'll have to remember to wrap the languages in the
-      *real* ``ugettext()`` in any code that uses ``LANGUAGES`` at runtime.
-
     * The ``LocaleMiddleware`` can only select languages for which there is a
       Django-provided base translation. If you want to provide translations
       for your application that aren't already in the set of translations
