%
% Gernot Hassenpflug wrote a lot of \file{lco}-files for use of Japanese
% envelope formats.  Markus Kohm, the author of \KOMAScript, adapted them to
% an extended version of \cls*{scrlttr2} and wrote a \file{dtx}-file with the
% moste recent \file{lco}-files. Table~\ref{tab:japan.envelopes} shows all
% \file{lco}-files of the supported envelopes with their datas.
