+=================
+External packages
+=================
+
+Django ships with a variety of extra, optional tools that solve common
+problems (``contrib.*``). For easier maintenance and to trim the size of the
+codebase, a few of those applications have been moved out to separate projects.
+
+Localflavor
+~~~~~~~~~~~
+
+``django-localflavor`` is a collection of utilities for particular countries
+and cultures.
+
+* `GitHub <https://github.com/django/django-localflavor>`__
+* `Documentation <https://django-localflavor.readthedocs.org/>`__
+* `PyPI <https://pypi.python.org/pypi/django-localflavor>`__
+
+Comments
+~~~~~~~~
+
+``django-contrib-comments`` can be used to attach comments to any model, so you
+can use it for comments on blog entries, photos, book chapters, or anything
+else. Most users will be better served with a custom solution, or a hosted
+product like Disqus.
