+      # Creates and returns a class that includes the ExampleGroupMethods
+      # module. Which ExampleGroup type is created depends on the directory of the file
+      # calling this method. For example, Spec::Rails will use different
+      # classes for specs living in <tt>spec/models</tt>,
+      # <tt>spec/helpers</tt>, <tt>spec/views</tt> and
+      # <tt>spec/controllers</tt>.

+      # type with an options Hash as the last argument:
+      #
+      #   describe "name", :type => :something_special do ...
+      #
+      # The reason for using different behaviour classes is to have different
+      # matcher methods available from within the <tt>describe</tt> block.
+      #
+      # See Spec::Example::ExampleFactory#register for details about how to
+      # register special implementations.
