+module Spec
+  module Runner
+    class Configuration
+      include Spec::Example::ArgsAndOptions
+      
+      # Chooses what mock framework to use. Example:
+      #
+      #   Spec::Runner.configure do |config|
+      #     config.mock_with :rspec, :mocha, :flexmock, or :rr
+      #   end
+      #
+      # To use any other mock framework, you'll have to provide your own
+      # adapter. This is simply a module that responds to the following
+      # methods:
+      #
+      #   setup_mocks_for_rspec
+      #   verify_mocks_for_rspec
+      #   teardown_mocks_for_rspec.
+      #
+      # These are your hooks into the lifecycle of a given example. RSpec will
+      # call setup_mocks_for_rspec before running anything else in each
+      # Example. After executing the #after methods, RSpec will then call
+      # verify_mocks_for_rspec and teardown_mocks_for_rspec (this is
+      # guaranteed to run even if there are failures in
+      # verify_mocks_for_rspec).
+      #
+      # Once you've defined this module, you can pass that to mock_with:
+      #
+      #   Spec::Runner.configure do |config|
+      #     config.mock_with MyMockFrameworkAdapter
+      #   end

+        when Symbol
+          mock_framework_path(mock_framework.to_s)
+        else

+      # :call-seq:
+      #   include(Some::Helpers)
+      #   include(Some::Helpers, More::Helpers)
+      #   include(My::Helpers, :type => :key)
+      #
+      # Declares modules to be included in multiple example groups
+      # (<tt>describe</tt> blocks). With no <tt>:type</tt>, the modules listed
+      # will be included in all example groups.
+      #
+      # Use <tt>:type</tt> to restrict
+      # the inclusion to a subset of example groups. The value assigned to
+      # <tt>:type</tt> should be a key that maps to a class that is either a
+      # subclass of Spec::Example::ExampleGroup or extends
+      # Spec::Example::ExampleGroupMethods and includes
+      # Spec::Example::ExampleMethods.
+      #
+      # For example, the rspec-rails gem/plugin extends Test::Unit::TestCase
+      # with Spec::Example::ExampleGroupMethods and includes
+      # Spec::Example::ExampleMethods in it. So if you have a module of helper
+      # methods for controller examples, you could do this:
+      #
+      #   config.include(ControllerExampleHelpers, :type => :controller)
+      #
+      # Only example groups that have that type will get the modules included:
+      #
+      #   describe Account, :type => :model do
+      #     # Will *not* include ControllerExampleHelpers
+      #   end
