## Using the Rackspace CDN provider

Creating a client is straight-forward:

``` js
  var rackspace = pkgcloud.cdn.createClient({
    provider: 'rackspace', // required
    username: 'your-user-name', // required
    password: 'your-password', // required
    authUrl: 'your identity service url' // required
  });
```
