title: RoR: Where is the "rails/info/properties" route defined?
body: <p>I'm running Rails 2.3.4. When I create a new rails project, the public/index.html file has a link named "About your application's environment" that points to "rails/info/properties". In dev mode, it gives a summary of the runtime environment. However, in production mode, it gives a 404 page cannot be found. </p>
  
  <p>Could someone point me in the direction of how and where the "rails/info/properties" route is configured? I'd just like to understand how it's set up. </p>
