How to create autonomous ruby applications?

I have created a very basic Ruby application that works totally okay inside the Heroku console (heroku is being run by the myapp.rb). I want to know the idea of making it run fully autonomously? I do not want Heroku console as a wrapper so that I can run my basic application I have just created make a independent application which can run with out any dependencies. This is actually only a basic application which reads a little news or updates from a website and emails the content to a predefined client. Simple. What should I put in CONFIG files. What should be the PROCFILE. Can any body please help in this regard. I will update you all if I get any success. Thanks for helping.
