-      module Option
-        # Defines configuration option
-        #
-        # When you call option, it defines two methods. One method will take place
-        # in the +Config+ class and the other method will take place in the
-        # +Builder+ class.
-        #
-        # The +name+ parameter will set both builder method and config attribute.
-        # If the +:as+ option is defined, the builder method will be the specified
-        # option while the config attribute will be the +name+ parameter.
-        #
-        # If you want to introduce another level of config DSL you can
-        # define +builder_class+ parameter.
-        # Builder should take a block as the initializer parameter and respond to function +build+
-        # that returns the value of the config attribute.
-        #
-        # ==== Options
-        #
-        # * [:+as+] Set the builder method that goes inside +configure+ block
-        # * [+:default+] The default value in case no option was set
-        #
-        # ==== Examples
-        #
-        #    option :name
-        #    option :name, as: :set_name
