I'm playing around with New Relic and want to alert New Relic to deploys. I can do this on the command line using:

```
curl -H "x-api-key:MY_API_KEY" -d "deployment[application_id]=MY_APP_ID "https://api.newrelic.com/deployments.xml

```

What should should I add to the capfile so capistrano runs the curl above upon deploy?

I know I can install the new relic gem and require it in the Capfile, but wanted to avoid the dependency.
