An intelligent database migrations library for the Django web framework. It is database-independent and DVCS-friendly, as well as a whole host of other features.

* Intelligent; it knows if you've missed out a migration or two
* Database independent, so there's no hassle if you need to move databases.
* Easy; it can write migrations for you, and it takes about a minute to
convert your app over to use South.
* Designed for a pluggable Django world; you can declare dependencies
between apps so they all migrate together correctly, and you can
still use syncdb for your non-migrated apps without it interfering.
