%% test-ptex.tex
%% =============
%% Typesetting test for (u)pLaTeX + dvipdfmx, yoko: a book design of
%% 13Q, 23H line feed, 42 chars x 33 lines (set solid), on a B5 variant
%% (182mm x 230mm) page with 25mm top and gutter margins.
%%
%%   uplatex test-ptex.tex && dvipdfmx test-ptex
%%   platex  test-ptex.tex && dvipdfmx test-ptex
%% The class is selected automatically (platex: jbook / uplatex: ujbook).
%% Since current pLaTeX also runs on the e-upTeX engine, the format is
%% detected via the internal kanji encoding.
%%
%% What to check:
%%   * SHG-EXPECT OK: 42 chars x 33 lines, no overflow.
%%   * SHG-POS OK on pages 1 (odd) and 2 (even): the first character
%%     sits in the top left square of the grid.
%%   * In the PDF, every character of the body text sits in a square.
