%D \module
%D [ file=m-zint,
%D version=2010.12.07,
%D title=\CONTEXT\ Extra Modules,
%D subtitle=Zint Barcode Generator,
%D author=Hans Hagen,
%D date=\currentdate,
%D copyright={PRAGMA ADE \& \CONTEXT\ Development Team}]
%C
%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
%D (PDF417) barcodes so therefore we now have this module. There
%D 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
%D feed names.
