%D \module
%D [ file=m-asymptote,
%D version=2017.03.24,
%D title=\CONTEXT\ Extra Modules,
%D subtitle=Asymptote,
%D author=Hans Hagen,

%C
%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
% \enabletrackers[sandbox,buffers.run]
%D Currently asymptote assumes \MKII\ but better is to only support \MKIV. A problem
%D is that asymptote has this hard coded while for \CONTEXT\ it's better to stick to
%D something simple:
%D
%D \starttyping
%D \starttext
%D
%D \startasymptotepage
%D some label
%D \stopasymptotepage
%D
%D \startasymptotepage
%D some label
%D \stopasymptotepage
%D
%D \stoptext
%D \stoptyping
%D
%D Which is then run with:
%D
%D \starttyping
%D context --nonstopmode --purge somefile.tex
%D \stoptyping
%D
%D For the moment add "settings.prc=true;" to a graphic that is meant to produce that
%D format. See end of file for some examples.
