title: How do I pass additional startup parameter for play apps in cloudfoundry
body: <p>When deploying a Play!2 app on cloudfoundry I would like to be able to specify at least one additional parameter to the startup command. </p>
  
  <p>Currently it seems like cloudfoundry uses the start script created by Play2 without any arguments, but to override the default application configuration with specific production values I need it to be called with -Dconfig.resource=prod.conf</p>
  
  <p>I couldn't find any way to do this, maybe through the manifest.yml but I wasn't able to find a specification for how to add this param. </p>
  
  <p>Appart from this I was able to successfully deploy play 2.0 and play 2.1 apps to cloudfoundry</p>
