title: Rails Faux-Rename Controller
body: <p>The title might be a little misleading, and I apologize for that. What I want to do is something like how Reddit renames their controller for their subreddits. They use the form /r/programming, instead of the longer /subreddit/programming. I know that they don't use Rails, but how would I go about doing that with Rails?</p>
  
  <p>Thanks!</p>
