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.

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.

Formtools

django-formtools is a collection of assorted utilities to work with forms.
