%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% Each of the following \DocInclude lines includes a file with extension
% .dtx. Each of these files may be typeset separately. For instance
% latex2e ltboxes.dtx
% will typeset the source of the LaTeX box commands.
%
% If this file is processed, each of these separate dtx files will be
% contained as a part of a single document. Using ltxdoc.cfg you can
% then optionally produce a combined index and/or change history for
% the entire source of the format file. Note that such a document will
% be quite large (about 400 pages).
