                     # * :desc - A description of the macro

                     #   string is passed to the macro)
                     #
                     # Macro blocks accept 2 or 3 arguments:
                     # * obj: the object that is rendered (eg. an Issue, a WikiContent...)
                     # * args: macro arguments
                     # * text: the block of text given to the macro (should be present only if the
                     #   macro accepts a block of text). text is a String or nil if the macro is
                     #   invoked without a block of text.
                     #
                     # Examples:
                     # By default, when the macro is invoked, the coma separated list of arguments
                     # is split and passed to the macro block as an array. If no argument is given
                     # the macro will be invoked with an empty array:
                     #
                     #   macro :my_macro do |obj, args|
                     #     # args is an array

                     #   end
                     #
                     # You can disable arguments spliting with the :parse_args => false option. In
                     # this case, the full string of arguments is passed to the macro:
                     #
                     #   macro :my_macro, :parse_args => false do |obj, args|

                     #   macro :my_macro do |obj, args, text|
                     #     # this macro accepts a block of text

                     # must be enclosed in parenthesis if any. A new line after the macro name or the
