%D These mp plugins started out as gimmick but might as well evolve into a more
%D grown up mechanism. It will take a while to have plgins for all the extensibles,
%D then we will look at the shapes. It makes no sense to have all shapes done this
%D way.
%D
%D You can load some demo plugins with:
%D
%D \starttyping
%D \usemathpluginlibrary[demo]
%D \stoptyping
%D
%D You can process \type {math-mps-imp-demo.mkxl} to get an idea of how this works.
