-- Tests generated from the code examples in the pgfmanual
--
-- The test files in testfiles-examples are generated automatically from the
-- manual sources with
--
--     l3build examples
--
-- Each \begin{codeexample} ... \end{codeexample} block becomes one box test
-- whose typeset content is dumped to the log and compared against a reference.
--
-- The tests are run for every supported engine.  Because the box dumps differ
-- between engines, each test has an engine specific reference file
-- (name.tlg for the std engine luatex, name.<engine>.tlg for the others).
-- checkengines is left unset so that all engines from build.lua (pdftex,
-- latexdvips, latexdvisvgm, luatex, xetex) are used.

-- copied in by checkinit_hook below are used instead.
