var pull = require('docker-pull')

pull('ubuntu', function (err) {
  console.log('was pulled?', !err)
})

var p = pull('ubuntu:14.04')

p.on('progress', function () {
  console.log('pulled %d new layers and %d/%d bytes', p.layers, p.transferred, p.length)
})

p.on('end', function () {
  console.log('pull is done')
})
```

## Api

#### `var p = pull(image, [options], [callback]])`

Pull a docker image. Returns an `EventEmitter`. Optionally you can specify the following options:

```js

  email:    'user@example.com'      // no default
}
```

#### `p.on('progress', progress)`
