"""Refactor South migrations to use settings.AUTH_USER_MODEL.
Inserts a backwards-compatible code-snippet in all
your schema migration files and uses a possibly customized user
model as introduced in Django 1.5.

Please note that this has nothing to do with changing
settings.AUTH_USER_MODEL to a new model. If you do this, stuff
will very likely break in reusable apps that have their own
migration trees.
