-class ::Module
-  # Defines a constant within a module/class ONLY if that constant does
-  # not already exist.
-  #
-  # This can be used to implement defaults in plugins/engines/libraries, e.g.
-  # if a plugin module exists:
-  #   module MyPlugin
-  #     default_constant :MyDefault, "the_default_value"
-  #   end
-  #
-  # then developers can override this default by defining that constant at
-  # some point *before* the module/plugin gets loaded (such as environment.rb)
-  def default_constant(name, value)
-    if !(name.is_a?(String) or name.is_a?(Symbol))
-      raise "Cannot use a #{name.class.name} ['#{name}'] object as a constant name"
-    end
-    if !self.const_defined?(name)
-      self.class_eval("#{name} = #{value.inspect}")
-    end

-  
-  # A mechanism for defining configuration of Modules. With this
-  # mechanism, default values for configuration can be provided within shareable
-  # code, and the end user can customise the configuration without having to
-  # provide all values.
-  #
-  # Example:
-  #
-  #  module MyModule
-  #    config :param_one, "some value"
-  #    config :param_two, 12345
-  #  end
-  #
-  # Those values can now be accessed by the following method
-  #
-  #   MyModule.config :param_one  
-  #     => "some value"
-  #   MyModule.config :param_two  
-  #     => 12345
-  #
-  # ... or, if you have overrriden the method 'config'
-  #
-  #   MyModule::CONFIG[:param_one]  
-  #     => "some value"
-  #   MyModule::CONFIG[:param_two]  
-  #     => 12345
-  #
-  # Once a value is stored in the configuration, it will not be altered
-  # by subsequent assignments, unless a special flag is given:
-  #
-  #   (later on in your code, most likely in another file)
-  #   module MyModule
-  #     config :param_one, "another value"
-  #     config :param_two, 98765, :force
-  #   end
-  #
-  # The configuration is now:
-  #
-  #   MyModule.config :param_one  
-  #     => "some value" # not changed
-  #   MyModule.config :param_two  
-  #     => 98765
-  #
-  # Configuration values can also be given as a Hash:
-  #
-  #   MyModule.config :param1 => 'value1', :param2 => 'value2'
-  #
-  # Setting of these values can also be forced:
-  #
-  #   MyModule.config :param1 => 'value3', :param2 => 'value4', :force => true
-  #
-  # A value of anything other than false or nil given for the :force key will
-  # result in the new values *always* being set.
-  def config(*args)

-    raise "config expects at least one argument" if args.empty?
