%
% To compile (i.e., tex) this file, do this:
%
%   lualatex demo-minimal.tex
%
% this makes TeX and Lua process this file "in parallel", or sort of.
% Lua processes the trees and diagrams in 2D ascii art in comments
% that are in the lines that start with "%:" or "%D", converts them to
% TeX code, and sends that code to TeX.
%
% The section 3 ("3. Semi-preprocessors") of the TUGBoat article about
% dednat6 explains what this "in parallel (or sort of)" means. The PDF
% for the article is here:
%
%   https://tug.org/TUGboat/tb39-3/tb123ochs-dednat.pdf
%   http://angg.twu.net/dednat6/2018tugboat-rev2.pdf
% 
% Section 3 ends with this paragraph:
%
%   `\pu' means "process until" - or, more precisely, _make dednat6
%   process everything until this point that it hasn't processed yet_.
%   The first \pu [in the example] processes the lines 1--26 of
%   foo.tex, and "outputs" - i.e., sends to TeX - the first
%   \defded{my-tree}; the second \pu processes the lines 28--34 of
%   foo.tex, and `outputs' the second \defded{my-tree}. Thus, it is
%   not technically true that TeX and dednat6 process foo.tex in
%   parallel; dednat6 goes later, and each \pu is a synchronization
%   point.
