%D \module
%D [ file=m-escrito,
%D version=2015.09.27,

%D subtitle=ESCRITO,
%D author={Taco Hoekwater \& Hans Hagen},

%C This module is part of the \CONTEXT\ macro||package and is

\registerctxluafile{m-escrito}{1.001}
%D This is a fun project and not meant for production (yet). It's a follow up on a
%D project by Taco presented at a Bacho\TeX\ meeting years ago. I probably messed up
%D the code so much that some things don't work but then, fonts are not really
%D supported well anyway. However for simple \POSTSCRIPT\ things work out ok.
%D
%D I (Hans) will occasionally have a look at the code. Who knows what our trips to
%D \TeX\ meetings lead to.
