%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
% We just assume lua specification instead of the graph ones that
% are limited by what mp can do. We support @ as replacement for
% the percent symbol. We also add a specifier when no one is given.
