+Feature: custom options
+
+  In order to seamlessly provide my users more options
+  As an Rspec extenstion-library author
+  I want to define new options on the Rspec.configuration
+
+  Scenario: boolean option with default settings
+    Given a file named "boolean_option_spec.rb" with:
+      """
+      Rspec.configure do |c|
+        c.add_option :custom_option, :type => :boolean
+      end

+          Rspec.configuration.custom_option?.should be_false
+        end
+      end
+      """
+    When I run "rspec boolean_option_spec.rb"
+    Then I should see "2 examples, 0 failures"
