I'm just starting out with Sequelize in Node.js and finding the documentation really lacking. I have a 'db' module in which I connect to the database via `Sequelize`, and this reads in configuration from an application-wide config file at `./config.json` relative to the root of my project. This is a nested configuration and extremely unlikely to be structured in the way that Sequelize wants a config file for the CLI.

Now I'm trying to use migrations and the documentation makes reference to a "config file". I know I can set the path to that config file, but what the heck do I put in it? It's not documented anywhere (that I've seen).
