+\begin{document}
+
+This is a test document for fontification support of verbatim
+\emph{macros} provided by \LaTeX{} and other packages within AUC\TeX.
+As it is not part of \verb|ert|-tests, it does not have an
+\verb|out|-counterpart.  Parsing should be enabled when loading this
+file, namely \verb|(setq TeX-parse-self t)| in \verb|.emacs|.
+
+\section{The problem}
+
+The \verb|verb| macro provided by vanilla \LaTeX{} does not receive
+any special fontification within AUC\TeX.  It is fontified with
+\verb|font-latex-sedate-face|.  Other \verb|verb| macros provided by
+packages like \verb|listings|, \verb|minted| or \verb|fancyvrb| are
+fontified with \verb|font-lock-keyword-face| as they are added to
+\verb|textual| keyword class within \verb|font-latex.el|.
+
+Next issue is that \verb|verb| macros from modern packages take an
+optional argument or even a mandatory argument before the
+\verb|verbatim| content.  This issue was not addressed in
+\verb|font-latex.el|.
+
+\section{The solution}
+
+\subsection{Vanilla \LaTeX}
+
+The issue with fontification of \verb|verb| macro is solved in
+\verb|font-latex.el| by adding \verb|("verb" "*")| to
+\verb|`font-latex-built-in-keyword-classes'|.  This construct
+fontifies only the macro itself---the argument is left out for
+syntactic fontification.
+
+\subsection{Optional argument}
+
+This issue can be fixed in \verb|font-latex.el| by extending the
+regexp for \verb|verb| macros with delimiters/braces in
+\verb|`font-latex-set-syntactic-keywords'| with:
+\begin{quote}
+  \verb|"\\(?:\\[[^][]*\\(?:\\[[^][]*\\][^][]*\\)*\\]\\)?"|
+\end{quote}
+The same line is used for matching optional arguments in verbatim
+environments.
