 Creating a Rubikon application is as simple as creating a Ruby class:
 
     require 'rubygems'
     require 'rubikon'
 
-    class MyApplication < Rubikon::Application
+    class MyApplication < Rubikon::Application::Base
     end
 
 If you save this code in a file called `myapp.rb` you can run it using
 `ruby myapp.rb`. Or you could even add a *shebang* (`#!/usr/bin/env ruby`) to
 the top of the file and make it executable. You would then be able to run it
 even more easily by typing `./myapp.rb`.
 
 Now go on and define what your application should do when the user runs it.
 This is done using `default`:
 
-    class MyApplication < Rubikon::Application
+    class MyApplication < Rubikon::Application::Base
 
       default do
         puts 'Hello World!'
       end
 
     end
 
 If you run this application it will just print `Hello World!`.

 Flags and options are easily added to your application's commands using
 Rubikon's DSL:
 
     flag :more
-    option :name, 2
+    option :name, [:who]
     command :hello do
-      ...
