+% \begin{function}{\ekvoptarg}
+% \begin{syntax}
+% \cs{ekvoptarg}\marg{next}\marg{default}
+% \end{syntax}
+% This macro will check for a following optional argument in brackets (|[]|)
+% expandably. After the optional argument there has to be a mandatory one. The
+% code in \meta{next} should expect two arguments (the processed optional
+% argument and the mandatory one). If there was an optional argument the
+% result will be \meta{next}\marg{optional}\meta{mandatory} (so the optional
+% argument will be wrapped in braces, the mandatory argument will be
+% untouched). If there was no optional argument the result will be
+% \meta{next}\marg{default}\marg{mandatory} (so the default will be used and
+% the mandatory argument will be wrapped in braces).
+% \end{function}
+% |\ekvoptarg| expands in exactly two steps and is alignment safe. It has its
+% limitations however. It can't tell the difference between |[| and |{[}|, so it
+% doesn't work if the mandatory argument is a single bracket. Also if the
+% optional argument should contain a nested closing bracket, the optional
+% argument has to use nested braces like so: |[{arg]ument}]|.
+% \example Say we have a macro that should take an optional argument defaulting
+% to 1:
+% \begin{lstlisting}[aboveskip=0pt,belowskip=0pt]
+% \newcommand\foo{\ekvoptarg\@foo{1}}
+% \newcommand\@foo[2]{Mandatory: #2\par Optional: #1}
+% \end{lstlisting}
+%
+% \begin{function}{\ekvoptargTF}
+% \begin{syntax}
+% \cs{ekvoptargTF}\marg{true}\marg{false}
+% \end{syntax}
+% This macro is similar to |\ekvoptarg|, but will result in
+% \meta{true}\marg{optional}\meta{mandatory} or \meta{false}\marg{mandatory}
+% instead of placing a default value.
+% \end{function}
+% |\ekvoptargTF| expands in exactly two steps and is alignment safe. It has the
+% same limitations as |\ekvoptarg|.
+% \example Say we have a macro that should behave differently depending on
+% whether there was an optional argument or not. This could be done with:
+% \begin{lstlisting}[aboveskip=0pt,belowskip=0pt]
+% \newcommand\foo{\ekvoptargTF\foo@a\foo@b}
+% \newcommand\foo@a[2]{Mandatory: #2\par Optional: #1}
+% \newcommand\foo@b[1]{Mandatory: #1\par No optional.}
+% \end{lstlisting}
+%
+% \begin{function}{\ekverr}
+% \begin{syntax}
+% \cs{ekverr}\marg{package}\marg{message}
+% \end{syntax}
+% This macro will throw an error fully expandably.\footnotemark\ The error
+% length is limited to a total length of 69~characters, and since ten
+% characters will be added for the formatting (\verb*|! | and
+% \verb*| Error: |) that leaves us with a total length for \meta{package} plus
+% \meta{message} of 59~characters. If the message gets longer \TeX\ will only
+% display the first 69~characters and append |\ETC.| to the end.
+%
+% Neither \meta{package} nor \meta{message} expand any further. Also
+% \meta{package} must not contain an explicit |\par| token or the token
+% |\thanks@jfbu|. No such restriction applies to \meta{message}.
+%
+% If |^^J| is set up as the |\newlinechar| (which is the case in \LaTeXe\ but
+% not in plain \TeX\ by default) you can use that to introduce line breaks in
+% your error message. However that doesn't change the message length limit.
+% \end{function}
+% \footnotetext{The used mechanism was to the best of my knowledge first
+% implemented by Jean-François Burnol.}
+% After your own error message some further text will be placed. The
+% formatting of that text will look good if |^^J| is the |\newlinechar|, else
+% not so much. That text will read:
+% \begin{verbatim}
+% ! Paragraph ended before \<an-expandable-macro>
+% completed due to above exception. If the error
+% summary is not comprehensible see the package
+% documentation.
+% I will try to recover now. If you're in inter-
+% active mode hit <return> at the ? prompt and I
+% continue hoping recovery was complete.
+% \end{verbatim}
+% Any clean up has to be done by you, |\ekverr| will expand to nothing after
+% throwing the error message.
+% \example Say we set up a small calculation which works with user input. In our
+% calculation we need a division, so have to watch out for division by zero. If
+% we detect such a case we throw an error and do the recovery by using the
+% biggest integer allowed in \TeX\ as the result.
+% \begin{lstlisting}
+% \newcommand*\mydivision[2]
+% {%
+% \number\numexpr
+% \ifnum\numexpr#2=0 % space here on purpose

+% 2147483647%
+% \else
+% (#1)/(#2)%
+% \fi
+% \relax
+% }
+% $(10+5)/(3-3)\approx\mydivision{10+5}{3-3}$
+% \end{lstlisting}
+% If that code gets executed the following will be the terminal output
+% \begin{verbatim}
+% Runaway argument?
+% ! my Error: division by 0. Setting result to 2147483647.
+% ! Paragraph ended before \<an-expandable-macro>

+% <to be read again>
+% \par
+% l.15 $(10+5)/(3-3)\approx\mydivision{10+5}{3-3}
+% $
