  * GIT Deploy to Pivotal Staging
  *
  * 1. Ensure this file exists in the root directory of your website
  *   on the staging server
  * 2. Update the $config variables below
  * 3. Browse to this file in your browser to "clone" the repo
  * 4. Setup a Webhook to auto-deploy:
  *     URL: http://nbm:nbm@{{site_domain_name}}/stage.php
  *     Status: Active
  *     Triggers: Repo push
  *
  * Everytime you push to the branch specified below, it'll
  * auto deploy to the Pivotal Staging server.
