+%    \section{Test files}
+%
+%    Here we test only the two main formatis: Plain~\TeX\ (with etex.src
+%    loaded) and \LaTeX, both with the \LuaTeX\ engine. Those correspond to
+%    the \texttt{luatex} and \texttt{lualatex} commands in \TeX\,Live.
+%
+%    We want to make sure we can globally and locally allocate $30000$
+%    registers of each kind, and still globally allocate $100$
+%    \verb+\insert+s. (Those numbers are not optimal, but they should be
+%    enough for testing purposes.)
