I'm a huge fan of Procfile. When I use a Procfile app, I know that regardless of the language or the configuration of processes, workers, clocks, or what-have-you, I can always get it up and running with a single `foreman start`.
This is a great tool, glad to see something this useful. My webapp has a 2-3 background scripts that need to be run, this is far better than nohup!
