 In a production application, you will probably want to schedule or queue notifications into a background job. Whether you're using [queue_classic](https://github.com/ryandotsmith/queue_classic), [resque](https://github.com/defunkt/resque), or rolling you own infrastructure, integrating Houston couldn't be simpler.
 
 Another caveat is that Houston doesn't manage device tokens for you. Infrastructures can vary dramatically for these kinds of things, so being agnostic and not forcing any conventions here is more a feature than a bug, perhaps. Treat it the same way as you would an e-mail address, associating one or many for each user account.

 Houston also comes with the `apn` binary, which provides a convenient way to test notifications from the command line.
 
 ```
 $ apn push "<token>" -c /path/to/apple_push_notification.pem -m "Hello from the command line!"
