%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.

%D Using \type {zint} seems to be the easiest way to generate (PDF417) barcodes so
%D therefore we now have this module. There are proper (also windows) binaries at:
%D
%D \starttyping
%D http://www.zint.org.uk
%D \stoptyping
%D
%D There is a bit more code than needed as we want to be able to feed names.
