%% test-basic.tex
%% ==============
%% Typesetting test for every engine: the footnotes of the boxes with
%% "page footnote" are page footnotes on the page of their marks.
%%
%%   pdflatex test-basic.tex   (or xelatex / lualatex)
%%   platex  test-basic.tex && dvipdfmx test-basic
%%   uplatex -jobname=test-basic "\def\CLS{ujarticle}\input test-basic"
%% The class is article by default; set \CLS for another one (jarticle,
%% ujarticle, ltjsarticle, ...).  With pTeX the class option dvipdfmx
%% is given.
%%
%% What is covered:
%%   * footnotes in the body text, and in the title, upper and lower
%%     part of a box, several in one box;
%%   * \footnote[<num>], \footnotemark + \footnotetext in a box;
%%   * a box with "page footnote" inside another one, and an ordinary
%%     box (a footnote of the box) inside a box with "page footnote";
%%   * an ordinary box for comparison;
%%   * \tcbox, a box defined by \newtcolorbox, and \tcbset{page footnote};
%%   * a box that does not fit at the bottom of a page and moves to the
%%     next page: its footnotes move with it.
%%
%% test-hyperref.tex runs this file with hyperref.
%%
%% What to check:
%%   * TPF-RESULT OK, TPF-COUNTER OK, and no error or warning.
