Yeah, thought about this, and would like your advice here: to confirm, you'd need to pass in the 'serialize' db object to that script in order to sync before global.db gets set, but for other cases, you'd have global.db, and wouldn't need a function that takes the parameter.

I can always do a bit of parameter logic (see below), but I'm not a fan of that. Suggestions welcome.

```
module.exports = function(sequelize) {
  if(arguments.length == 0 && global.db) sequelize = global.db // assume there isn't the case where either you call without argument and without global.db or you call with a bad sequelize object
}
```
