Example of config with additional log transports?

I have a config.json as such for testing:

``` json
{
  "log": {
    "couchdb": {
      "host": "localhost",
      "db" : "winston_logs"
    }
  }
}
```

When the app boots and the broadway log plugin kicks in, its winston module doesn't have access to the Couchdb transport from winston-couchdb.  What is the proper way to configure logging?
