-      use Pistol, :files => Dir[__FILE__, "./app/**/*.rb"]
+      use Pistol, Dir[__FILE__, "./app/**/*.rb"] do

     Dir["./app/**/*.rb"].each { |file| require file }
 
 ### What this does:
 
-1. It marks `app.rb` as the main application file. It's assumed that app.rb
-   handles all the loading, boiler plate, etc.
-2. It reloads everything in `app/**/*.rb`. You can of course specify
-   other paths (e.g. `./config/*.rb`, `./lib/*.rb`).
+1. It instructs Pistol to watch for changes in any of the files passed.
+2. If changes occur, the block is executed.
 
 ### Only in development?
 
 Sure. Simply change it to:
 
     class App < Sinatra::Base
       configure :development do
-        use Pistol, :files => Dir[__FILE__, "./app/**/*.rb"]
+        use Pistol, Dir[__FILE__, "./app/**/*.rb"] do
+          reset! and load(__FILE__)
+        end
       end
     end
