Support for sophisticated migrations
I've always maintained the view that anything beyond the APIs currently available would be best suited for a third party package, and I believe maybe one or two such exist. Any type of automatic schema migrator seems like an invitation to disaster and will never be included as part of peewee.
 Thanks for the quick reply, sounds good, I'll have a think about how this might be implemented as a third party module and will follow up for feedback at a later date.
 @foxx Have a look to https://github.com/klen/peewee_migrate

As mentioned in [Peewee Docs](http://docs.peewee-orm.com/en/latest/peewee/playhouse.html#schema-migrations);

Other framework implementations, such as South and Django Migrations, are quite infuriating to use so I'd be interested to hear your thoughts on how such a tool would be constructed @coleifer.

Would this tool be within the scope of Peewee core or playhouse? If so, are there any plans on the roadmap to start working on such a tool? I can put a certain amount of time towards helping out with this, so if it needs volunteers then count me in.
