South, intelligent schema migrations for Django apps.

South is:

* 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.
* Useful for data too; you can write migrations to transform legacy data.
* Better (we think, anyway) than the alternatives.
