%
%    If running \LaTeX, load \texttt{etex.sty}. If not, either
%    \texttt{etex.src} was loaded at format generation time, or we cannot do
%    anything.

%
%    To the best of my (mpg) knowledge, all Plain-based formats built with
%    \eTeX-enabled engines in \TeX\,Live load \texttt{etex.src}. However,
%    let's be careful and check that \texttt{etex.sty} or \texttt{src} is
%    loaded.

\expandafter\ifx\csname et@xins\endcsname\relax
  %%TODO: issue a warning here
\else
%    \end{macrocode}
%
%    First, increase the upper bound for all kinds of registers. Copy code to
%    avoid defining a macro.
%
%    \begin{macrocode}
  \ifnum\count270=32768 \count270=65536 \fi
  \ifnum\count271=32768 \count271=65536 \fi
  \ifnum\count272=32768 \count272=65536 \fi
  \ifnum\count273=32768 \count272=65536 \fi
  \ifnum\count273=32768 \count273=65536 \fi

%    \end{macrocode}
%
%    Finally, make allocation of \verb|\count|, \verb|\dimen|, \verb|skip| and
%    \verb|\box| start with numbers $>255$, in order to free the lower numbers
%    for insertions. Be careful with \verb|\new...| macros which are
%    \verb|\outer| in Plain, since we're in the middle of an \verb|\if| test.
%
%    \begin{macrocode}
  \expandafter\let\csname newcount\endcsname\globcount
  \expandafter\let\csname newdimen\endcsname\globdimen
  \expandafter\let\csname newskip\endcsname\globskip
  \expandafter\let\csname newbox\endcsname\globbox
%    \end{macrocode}
%
%    That's all folks!

%    \begin{macrocode}

%    \end{macrocode}
%
%    \section{Test files}
%
%    Here we test only the two main formats: Plain~\TeX\ (with
%    \texttt{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.)
