\section*{Example for regstats}

This example demonstrates the use of package\newline
\textsf{regstats}, v1.1a as of 2023-04-04.\newline
The used options were \texttt{left=true,timer=true}.\par
\texttt{left=false,timer=false} would be the defaults.\newline

Regarding the use of
\makeatletter%
\ \@ifundefined{eTeX}{\hbox{$\m@th \varepsilon $-\TeX}}{\eTeX}, %
\makeatother%
the \texttt{morewrite} package, the reservation of \texttt{insert}s,
and using more \texttt{math families} please see the documentation!\newline

For the resulting message, please compile \texttt{regstats-example.tex}
and have a look at the end of its \texttt{.log}-file.\newline

Because the compilation time for this example is usually quite short,
option \texttt{timer} is not demonstrated very spectacular.\newline

To test a register type for the number of available registers,
uncomment the respective line below and set the number to an interesting value.
