+%
+% \paragraph{Transition of package maintenance}
+% The \TeX\ world lost contact with Carsten Heinz in late 2004, shortly after 
+% he released version 1.3b of the \packagename{listings} package.  After many
+% attempts to reach him had failed, Hendri Adriaens took over maintenance of
+% the package in accordance with the LPPL's procedure for abandoned packages.
+% He then passed the maintainership of the package to Brooks Moses, who had
+% volunteered for the position while this procedure was going through.
+%
+% This release, version 1.4, is the first substantial bugfix release since 
+% I accepted maintainership of the package.  I would like to thank the
+% numerous people who reported bugs to me, and particularly those who 
+% suggested fixes.  Thanks in addition to those who provided
+% new language definitions and suggestions for improvements.
+%
+% \paragraph{News and changes}
+% Version 1.4 is the fourth bugfix release.  There are no substantial changes
+% in this version, but a number of minor changes and fixes.  The primary news
+% is that the documentation has been substantially copyedited, and improved 
+% in a number of ways to document workarounds and things learned from the 
+% recent bug reports.
+%
+% A |numberbychapter| key has been added, to control whether listings are 
+% numbered sequentially or by chapter in document classes that provide 
+% chapters.
+%
+% The |\lstMakeShortInline| command can be used to define single-character
+% inline-listing macros, much like the \packagename{shortvrb} package
+% allows for verbatim inline text.
+%
+% A new |spaceflexible| column alignment style has been added, which is
+% similar to the |flexible| style except that it only inserts extra space
+% to recover the column alignment at locations where there is already
+% existing space.
+%
+% A |s| string type has been added, akin to the |s| comment type.  This is
+% used in the Ruby language definition.
+%
+% The |\lst@for| routine has been sped up substantially, thanks to some code
+% provided by Hendri Adriaens.  Hopefully this will result in a significant
+% speedup of the runtime of the overall package.
+%
+% Among the bugs fixed are the |*| option to |texcs|, which was quite badly 
+% broken; the interaction of background colors with inline listings and with
+% frames; listing captions being broken in AMS document classes; and better
+% integration of the list of listings with KOMAscript document class and other
+% document clases that use the |\float@addtolists| mechanism.
+%
+% The following languages were added: |command.com| (DOS/Windows) batch files, 
+% Common Intermediate Language, Lingo, Postscript, PSTricks, and SPARQL.
+% The following dialects of existing languages were added: Ada (2005),
+% Assembler (Motorola68k), and Mathematica (5.2).  The definitions for ABAP,
+% Fortran, Octave, Python, Ruby, and TCL have been improved.  Thanks go to the
+% contributers.
+%
+% \vfill
+% \paragraph{Thanks}
+% There are many people I have to thank for fruitful communication, posting
+% their ideas, giving error reports, adding programming languages to
+% \texttt{lstdrvrs.dtx}, and so on. Their names are listed in section
+% \ref{uClosingAndCredits}.
+%
+% \paragraph{Trademarks}
+% Trademarks appear throughout this documentation without any trademark
+% symbol; they are the property of their respective trademark owner.

+% \section{Getting started}\label{uGettingStarted}
+%
+%
+% \subsection{A minimal file}\label{uAMinimalFile}
+%
+% Before using the \packagename{listings} package, you should be familiar with
+% the \LaTeX\ typesetting system. You need not to be an expert.
+% Here is a minimal file for \packagename{listings}.
+% \begin{verbatim}
+%    \documentclass{article}
+%    \usepackage{listings}
+%
+%    \begin{document}
+%    \lstset{language=Pascal}
+%
+%      % Insert Pascal examples here.
+%
+%    \end{document}\end{verbatim}
+% Now type in this first example and run it through \LaTeX.
+% \begin{advise}
+% \item Must I do that really?
+%       \advisespace
+%       Yes and no. Some books about programming say this is good.
+%       What a mistake! Typing takes time---which is wasted if the code is clear to
+%       you. And if you need that time to understand what is going on, the
+%       author of the book should reconsider the concept of presenting the
+%       crucial things---you might want to say that about this guide even---or
+%       you're simply inexperienced with programming. If only the latter case
+%       applies, you should spend more time on reading (good) books about
+%       programming, (good) documentations, and (good) source code from other
+%       people. Of course you should also make your own experiments.
+%       You will learn a lot. However, running the example through \LaTeX\ 
+%       shows whether the \packagename{listings} package is installed correctly.
+% \item The example doesn't work.
+%       \advisespace
+%       Are the two packages \packagename{listings} and \packagename{keyval}
+%       installed on your system? Consult the administration tool of your
+%       \TeX\ distribution, your system administrator, the local \TeX\ and
+%       \LaTeX\ guides, a \TeX\ FAQ, and section \ref{rInstallation}---in
+%       that order. If you've checked \emph{all} these sources and are
+%       still helpless, you might want to write a post to a \TeX\ newsgroup
+%       like \texttt{comp.text.tex}.
+% \item Should I read the software license before using the package?
+%       \advisespace
+%       Yes, but read this \emph{Getting started} section first to decide
+%       whether you are willing to use the package.^^A ;-)
+% \end{advise}
+%
+%
+% \subsection{Typesetting listings}
+%
+% Three types of source codes are supported: code snippets, code segments, and
+% listings of stand alone files.  Snippets are placed inside paragraphs and the
+% others as separate paragraphs---the difference is the same as between text
+% style and display style formulas.
+% \begin{advise}
+% \item No matter what kind of source you have, if a listing contains national
+%       characters like \'e, \L, \"a, or whatever, you must tell the
+%       package about it! Section \lstref{uSpecialCharacters} discusses this issue.
+% \end{advise}
+%
+% \paragraph{Code snippets}
+% The well-known \LaTeX\ command |\verb| typesets code snippets verbatim.
+% The new command |\lstinline| pretty-prints the code, for example
+%`\lstinline!var i:integer;!' is typeset by
+%`{\rstyle|\lstinline|}|!var i:integer;!|'. The exclamation marks delimit
+% the code and can be replaced by any character not in the code;
+% |\lstinline$var i:integer;$| gives the same result.
+%
+% \paragraph{Displayed code}
+% The \texttt{lstlisting} environment typesets the enclosed source code. Like
+% most examples, the following one shows verbatim \LaTeX\ code on the right
+% and the result on the left. You might take the right-hand side, put it into
+% the minimal file, and run it through \LaTeX.
+% \begin{lstsample}[lstlisting]{}{}
+%    \begin{lstlisting}
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%
+%    Write('Case insensitive ');
+%    WritE('Pascal keywords.');
+%    \end{lstlisting}
+% \end{lstsample}
+% It can't be easier.
+% \begin{advise}
+% \item That's not true. The name `\texttt{listing}' is shorter.
+%       \advisespace
+%       Indeed. But other packages already define environments with that name.
+%       To be compatible with such packages, all commands and environments of
+%       the \packagename{listings} package use the prefix `\texttt{lst}'.
+% \end{advise}
+% The environment provides an optional argument. It tells the package to
+% perform special tasks, for example, to print only the lines 2--5:
+% \begin{lstsample}{\lstset{frame=trbl,framesep=0pt}\label{gFirstKey=ValueList}}{}
+%    \begin{lstlisting}[firstline=2,
+%                       lastline=5]
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%
+%    Write('Case insensitive ');
+%    WritE('Pascal keywords.');
+%    \end{lstlisting}
+% \end{lstsample}
+% \begin{advise}
+% \item Hold on! Where comes the frame from and what is it good for?
+%       \advisespace
+%       You can put frames around all listings except code snippets.
+%       You will learn how later. The frame shows that empty lines at the end
+%       of listings aren't printed. This is line 5 in the example.
+% \item Hey, you can't drop my empty lines!
+%       \advisespace
+%       You can tell the package not to drop them:
+%       The key `\ikeyname{showlines}' controls these empty lines and is
+%       described in section \ref{rTypesettingListings}. Warning: First
+%       read ahead on how to use keys in general.
+% \item I get obscure error messages when using `\ikeyname{firstline}'.
+%       \advisespace
+%       That shouldn't happen. Make a bug report as described in section
+%       \lstref{uTroubleshooting}.
+% \end{advise}
+%
+% \paragraph{Stand alone files}
+% Finally we come to |\lstinputlisting|, the command used to pretty-print
+% stand alone files. It has one optional and one file name argument.
+% Note that you possibly need to specify the relative path to the file.
+% Here now the result is printed below the verbatim code since both together
+% don't fit the text width.
+% \begin{lstsample}{\lstset{comment=[l]\%,columns=fullflexible}}{\lstset{alsoletter=\\,emph=\\lstinputlisting,emphstyle=\rstyle}\lstaspectindex{\lstinputlisting}{}}
+%    \lstinputlisting[lastline=4]{listings.sty}
+% \end{lstsample}
+% \begin{advise}
+% \item The spacing is different in this example.
+%       \advisespace
+%       Yes. The two previous examples have aligned columns, i.e.~columns with
+%       identical numbers have the same horizontal position---this package
+%       makes small adjustments only. The columns in the example here are not
+%       aligned. This is explained in section \ref{uFixedAndFlexibleColumns}
+%       (keyword: full flexible column format).
+% \end{advise}
+%
+% Now you know all pretty-printing commands and environments. It remains
+% to learn the parameters which control the work of the \packagename{listings}
+% package. This is, however, the main task. Here are some of them.
+%
+%
+% \subsection{Figure out the appearance}\label{gFigureOutTheAppearance}
+%
+% Keywords are typeset bold, comments in italic shape, and spaces in strings
+% appear as \textvisiblespace. You don't like these settings? Look at this:
+%\ifcolor
+% \begin{lstxsample}[basicstyle,keywordstyle,identifierstyle,commentstyle,stringstyle,showstringspaces]
+%    \lstset{% general command to set parameter(s)
+%        basicstyle=\small,          % print whole listing small
+%        keywordstyle=\color{black}\bfseries\underbar,
+%                                    % underlined bold black keywords
+%        identifierstyle=,           % nothing happens
+%        commentstyle=\color{white}, % white comments
+%        stringstyle=\ttfamily,      % typewriter type for strings
+%        showstringspaces=false}     % no special string spaces
+% \end{lstxsample}
+%\else
+% \begin{lstxsample}[basicstyle,keywordstyle,identifierstyle,commentstyle,stringstyle,showstringspaces]
+%    \lstset{% general command to set parameter(s)
+%        basicstyle=\small,          % print whole listing small
+%        keywordstyle=\bfseries\underbar,
+%                                    % underlined bold keywords
+%        identifierstyle=,           % nothing happens
+%        commentstyle=\itshape,      % default
+%        stringstyle=\ttfamily,      % typewriter type for strings
+%        showstringspaces=false}     % no special string spaces
+% \end{lstxsample}
+%\fi
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%
+%    Write('Case insensitive ');
+%    WritE('Pascal keywords.');
+%    \end{lstlisting}
+% \end{lstsample}
+%\ifcolor
+% \begin{advise}
+% \item You've requested white coloured comments, but I can see the comment
+%       on the left side.
+%       \advisespace
+%       There are a couple of possible reasons:
+%       (1) You've printed the documentation on nonwhite paper.
+%       (2) If you are viewing this documentation as a \texttt{.dvi}-file, your
+%           viewer seems to have problems with colour specials. Try to print
+%           the page on white paper.
+%       (3) If a printout on white paper shows the comment, the colour
+%           specials aren't suitable for your printer or printer driver.
+%           Recreate the documentation and try it again---and ensure that
+%           the \packagename{color} package is well-configured.
+% \end{advise}
+%\fi
+% The styles use two different kinds of commands. |\ttfamily| and |\bfseries|
+% both take no arguments but |\underbar| does; it underlines the following
+% argument. In general, the \emph{very last} command may read exactly one
+% argument, namely some material the package typesets. There's one exception.
+% The last command of \ikeyname{basicstyle} \emph{must not} read any
+% tokens---or you will get deep in trouble.
+% \begin{advise}
+% \item `|basicstyle=\small|' looks fine, but comments look really bad with
+%       `|commentstyle=\tiny|' and empty basic style, say.
+%       \advisespace
+%       Don't use different font sizes in a single listing.
+% \item But I really want it!
+%       \advisespace
+%       No, you don't.
+%^^A       The package adjusts internal data after selecting the basic style at
+%^^A       the beginning of each listing. This is a problem if you change the
+%^^A       font size for comments or strings, for example.
+%^^A       Section \ref{rColumnAlignment} shows how to overcome this.
+%^^A       But once again: Don't use different font sizes in a single listing
+%^^A       unless you really know what you are doing.
+% \end{advise}
+%
+% \paragraph{Warning}\label{wStrikingStyles}
+% You should be very careful with striking styles; the recent example is rather
+% moderate---it can get horrible. \emph{Always use decent highlighting.}
+% Unfortunately it is difficult to give more recommendations since they depend
+% on the type of document you're creating. Slides or other presentations often
+% require more striking styles than books, for example.
+% In the end, it's \emph{you} who have to find the golden mean!
+%
+%
+% \subsection{Seduce to use}\label{gSeduceToUse}
+%
+% You know all pretty-printing commands and some main parameters. Here now
+% comes a small and incomplete overview of other features. The table of
+% contents and the index also provide information.
+%
+% \paragraph{Line numbers}
+% are available for all displayed listings, e.g.~tiny numbers on the left, each
+% second line, with 5pt distance to the listing:
+% \begin{lstxsample}[numbers,numberstyle,stepnumber,numbersep]
+%    \lstset{numbers=left, numberstyle=\tiny, stepnumber=2, numbersep=5pt}
+% \end{lstxsample}
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%
+%    Write('Case insensitive ');
+%    WritE('Pascal keywords.');
+%    \end{lstlisting}
+% \end{lstsample}
+% \begin{advise}
+% \item I can't get rid of line numbers in subsequent listings.
+%       \advisespace
+%       `|numbers=none|' turns them off.
+% \item Can I use these keys in the optional arguments?
+%       \advisespace
+%       Of course. Note that optional arguments modify values for one
+%       particular listing only: you change the appearance, step or distance
+%       of line numbers for a single listing. The previous values are
+%       restored afterwards.
+% \end{advise}
+% The environment allows you to interrupt your listings: you can end a listing
+% and continue it later with the correct line number even if there are other
+% listings in between. Read section \ref{uLineNumbers} for a thorough
+% discussion.
+%
+% \paragraph{Floating listings}
+% Displayed listings may float:
+% \begin{lstsample}{\lstset{frame=tb}}{}
+%    \begin{lstlisting}[float,caption=A floating example]
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%
+%    Write('Case insensitive ');
+%    WritE('Pascal keywords.');
+%    \end{lstlisting}
+% \end{lstsample}
+% Don't care about the parameter \ikeyname{caption} now. And if you put the
+% example into the minimal file and run it through \LaTeX, please don't wonder:
+% you'll miss the horizontal rules since they are described elsewhere.
+% \begin{advise}
+% \item \LaTeX's float mechanism allows one to determine the placement of floats.
+%       How can I do that with these?
+%       \advisespace
+%       You can write `|float=tp|', for example.
+% \end{advise}
+%
+% \paragraph{Other features}
+% There are still features not mentioned so far: automatic breaking of long
+% lines, the possibility to use \LaTeX\ code in listings, automated indexing,
+% or personal language definitions.
+% One more little teaser? Here you are. But note that the result is not
+% produced by the \LaTeX\ code on the right alone. The main parameter is
+% hidden.
+% \begin{lstsample}{\lstset{literate={:=}{{$\gets$}}1 {<=}{{$\leq$}}1 {>=}{{$\geq$}}1 {<>}{{$\neq$}}1}}{}
+%    \begin{lstlisting}
+%    if (i<=0) then i := 1;
+%    if (i>=0) then i := 0;
+%    if (i<>0) then i := 0;
+%    \end{lstlisting}
+% \end{lstsample}
+%
+% You're not sure whether you should use \packagename{listings}?
+% Read the next section!
+%
+%
+% \subsection{Alternatives}
+%
+% \begin{advise}
+% \item Why do you list alternatives?
+%       \advisespace
+%       Well, it's always good to know the competitors.^^A :-)
+% \item I've read the descriptions below and the \packagename{listings} package
+%       seems to incorporate all the features. Why should I use one of the
+%       other programs?
+%       \advisespace
+%       Firstly, the descriptions give a taste and not a complete overview,
+%       secondly, \packagename{listings} lacks some properties, and, ultimately,
+%       you should use the program matching your needs most precisely.
+% \end{advise}
+% This package is certainly not the final utility for typesetting source code.
+% Other programs do their job very well, if you are not satisfied with
+% \packagename{listings}. Some are independent of \LaTeX, others come as
+% separate program plus \LaTeX\ package, and others are packages which
+% don't pretty-print the source code. The second type includes converters,
+% cross compilers, and preprocessors. Such programs create \LaTeX\ files
+% you can use in your document or stand alone ready-to-run \LaTeX\ files.
+%
+% Note that I'm not dealing with any literate programming tools here, which
+% could also be alternatives. However, you should have heard of the
+% \texttt{WEB} system, the tool Prof.~Donald E.~Knuth developed and made use
+% of to document and implement \TeX.
+%
+% \paragraph{\href{http://www.infres.enst.fr/~demaille/a2ps}{\packagename{a2ps}}}
+% started as `ASCII to PostScript' converter, but today you can invoke the
+% program with \texttt{--pretty-print=}\meta{language} option. If your
+% favourite programming language is not already supported, you can write your
+% own so-called style sheet. You can request line numbers, borders, headers,
+% multiple pages per sheet, and many more. You can even print symbols like
+% $\forall$ or $\alpha$ instead of their verbose forms. If you just want
+% program listings and not a document with some listings, this is the best
+% choice.
+%
+% \paragraph{\href{http://www.ctan.org/tex-archive/nonfree/support/lgrind}{\packagename{LGrind}}}
+% is a cross compiler and comes with many predefined programming languages.
+% For example, you can put the code on the right in your document, invoke
+% \packagename{LGrind} with \texttt{-e} option (and file names), and run the
+% created file through \LaTeX. You should get a result similar to the
+% left-hand side:
+% \begin{center}
+% \begin{minipage}{0.45\linewidth}
+%\iflgrind
+%    \LGindent=0pt
+%    \LGinlinefalse\LGbegin\lgrinde
+%    \L{\LB{\K{for}_\V{i}:=\V{maxint}_\K{to}_\N{0}_\K{do}}}
+%    \L{\LB{\K{begin}}}
+%    \L{\LB{____\C{}\{_do_nothing_\}\CE{}}}
+%    \L{\LB{\K{end};}}
+%    \L{\LB{}}
+%    \L{\LB{\V{Write}(\S{}{'}Case_insensitive_{'}\SE{});}}
+%    \L{\LB{\V{WritE}(\S{}{'}Pascal_keywords.{'}\SE{});}}
+%    \endlgrinde\LGend
+%\else
+%    \packagename{LGrind} not installed.
+%\fi
+% \end{minipage}
+% \begin{minipage}{0.45\linewidth}
+% \begin{verbatim}
+% %[
+% for i:=maxint to 0 do
+% begin
+%     { do nothing }
+% end;
+%
+% Write('Case insensitive ');
+% WritE('Pascal keywords.');
+% %]\end{verbatim}
+% \end{minipage}
+% \end{center}
+% If you use |%(| and |%)| instead of |%[| and |%]|, you get a code snippet
+% instead of a displayed listing. Moreover you can get line numbers to the
+% left or right, use arbitrary \LaTeX\ code in the source code, print symbols
+% instead of verbose names, make font setup, and more. You will (have to)
+% like it (if you don't like \packagename{listings}).
+%
+% Note that \packagename{LGrind} contains code with a no-sell license and is
+% thus nonfree software.
+%
+% \paragraph{\href{ftp://axp3.sv.fh-mannheim.de/cvt2latex}{\packagename{cvt2ltx}}}
+% is a family of `source code to \LaTeX' converters for C, Objective C, \Cpp,
+% IDL and Perl. Different styles, line numbers and other qualifiers can be
+% chosen by command-line option. Unfortunately it isn't documented how other
+% programming languages can be added.
+%
+% \paragraph{\href{http://www.ctan.org/tex-archive/support/C++2LaTeX-1_1pl1}{\packagename{\Cpp2\LaTeX}}}
+% is a C/\Cpp\ to \LaTeX\ converter. You can specify the fonts for comments,
+% directives, keywords, and strings, or the size of a tabulator. But as far as
+% I know you can't number lines.
+%
+% \paragraph{\href{http://www.ctan.org/tex-archive/support/slatex}{\packagename{S\LaTeX}}}
+% is a pretty-printing Scheme program (which invokes \LaTeX\ automatically)
+% especially designed for Scheme and other Lisp dialects. It supports stand
+% alone files, text and display listings, and you can even nest the
+% commands/environments if you use \LaTeX\ code in comments, for example.
+% Keywords, constants, variables, and symbols are definable and use of
+% different styles is possible. No line numbers.
+%
+% \paragraph{\href{http://www.ctan.org/tex-archive/support/tiny_c2l}{\packagename{tiny\textunderscore c2ltx}}}
+% is a C/\Cpp/Java to \LaTeX\ converter based on \packagename{cvt2ltx} (or the
+% other way round?). It supports line numbers, block comments, \LaTeX\ code
+% in/as comments, and smart line breaking. Font selection and tabulators are
+% hard-coded, i.e.~you have to rebuild the program if you want to change the
+% appearance.
+%
+% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/misc}{\packagename{listing}}}
+% ---note the missing \packagename{s}---is not a pretty-printer and the
+% aphorism about documentation at the end of \texttt{listing.sty} is not
+% true.\space ^^A :-)
+% It defines |\listoflistings| and a nonfloating environment for listings.
+% All font selection and indention must be done by hand. However, it's
+% useful if you have another tool doing that work, e.g.~\packagename{LGrind}.
+%
+% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/alg}{\packagename{alg}}}
+% provides essentially the same functionality as \packagename{algorithms}.
+% So read the next paragraph and note that the syntax will be different.
+%
+% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/algorithms}{\packagename{algorithms}}}
+% goes a quite different way. You describe an algorithm and the package
+% formats it, for example
+% \begin{center}
+% \begin{minipage}{0.45\linewidth}
+%\ifalgorithmicpkg
+%    \begin{algorithmic}
+%    \IF {$i\leq0$}
+%    \STATE $i\gets1$
+%    \ELSE\IF {$i\geq0$}
+%    \STATE $i\gets0$
+%    \ENDIF\ENDIF
+%    \end{algorithmic}
+%\else
+%    \packagename{algorithms} not installed.
+%\fi
+% \end{minipage}
+% \begin{minipage}{0.45\linewidth}
+% \begin{verbatim}
+%\begin{algorithmic}
+%\IF{$i\leq0$}
+%\STATE $i\gets1$
+%\ELSE\IF{$i\geq0$}
+%\STATE $i\gets0$
+%\ENDIF\ENDIF
+%\end{algorithmic}\end{verbatim}
+% \end{minipage}
+% \end{center}
+% As this example shows, you get a good looking algorithm even from a bad
+% looking input. The package provides a lot more constructs like |for|-loops,
+% |while|-loops, or comments. You can request line numbers, `ruled', `boxed'
+% and floating algorithms, a list of algorithms, and you can customize the
+% terms \textbf{if}, \textbf{then}, and so on.
+%
+% \paragraph{\href{http://www.mimuw.edu.pl/~wolinski/pretprin.html}{\packagename{pretprin}}}
+% is a package for pretty-printing texts in formal languages---as the title
+% in TUGboat, Volume 19 (1998), No.~3 states. It provides environments which
+% pretty-print \emph{and} format the source code. Analyzers for Pascal and
+% Prolog are defined; adding other languages is easy---if you are or get a bit
+% familiar with automatons and formal languages.
+%
+% \paragraph{\packagename{alltt}}
+% defines an environment similar to \texttt{verbatim} except that |\|, |{| and
+% |}| have their usual meanings. This means that you can use commands in the
+% verbatims, e.g.~select different fonts or enter math mode.
+%
+% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/moreverb}{\packagename{moreverb}}}
+% requires \packagename{verbatim} and provides verbatim output to a file,
+% `boxed' verbatims and line numbers.
+%
+% \paragraph{\packagename{verbatim}}
+% defines an improved version of the standard \texttt{verbatim} environment and
+% a command to input files verbatim.
+%
+% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/fancyvrb}{\packagename{fancyvrb}}}
+% is, roughly speaking, a superset of \packagename{alltt},
+% \packagename{moreverb}, and \packagename{verbatim}, but many more parameters
+% control the output. The package provides frames, line numbers on the left or
+% on the right, automatic line breaking (difficult), and more. For example, an
+% interface to \packagename{listings} exists, i.e.~you can pretty-print source
+% code automatically.
+% The package \packagename{fvrb-ex} builds on \packagename{fancyvrb} and
+% defines environments to present examples similar to the ones in this guide.
+%
+%
+% \section{The next steps}\label{uTheNextSteps}
+%
+% Now, before actually using the \packagename{listings} package, you should
+% \emph{really} read the software license. It does not cost much time and
+% provides information you probably need to know.
+%
+%
+% \subsection{Software license}\label{uSoftwareLicense}
+%
+% The files \texttt{listings.dtx} and \texttt{listings.ins} and all
+% files generated from only these two files are referred to as `the
+% \packagename{listings} package' or simply `the package'.
+% \texttt{lstdrvrs.dtx} and the files generated from that file are
+% `drivers'.
+%
+% \paragraph{Copyright}
+%   The \packagename{listings} package is copyright 1996--2004 Carsten Heinz,
+%   and copyright 2006 Brooks Moses.  The drivers are copyright any individual
+%   author listed in the driver files.
+%
+% \paragraph{Distribution and modification}
+%   The \packagename{listings} package and its drivers may be distributed
+%   and/or modified under the conditions of the LaTeX Project Public License,
+%   either version 1.3 of this license or (at your option) any later version.
+%   The latest version of this license is in
+%      \href{http://www.latex-project.org/lppl.txt}{http://www.latex-project.org/lppl.txt}
+%   and version 1.3 or later is part of all distributions of LaTeX version
+%  2003/12/01 or later.
+%
+% \paragraph{Contacts}
+%   Read section \lstref{uTroubleshooting} on how to submit a bug report.
+%   Send all other comments, ideas, and additional programming languages to
+%   \lstemail\ using \texttt{listings} as part of the subject.
+%
+%
+% \subsection{Package loading}\label{uPackageLoading}
+%
+% As usual in \LaTeX, the package is loaded by
+%    |\usepackage[|\meta{options}|]{listings}|,
+% where |[|\meta{options}|]| is optional and gives a comma separated list of
+% options. Each either loads an additional \packagename{listings} aspect, or
+% changes default properties. Usually you don't have to take care of such
+% options. But in some cases it could be necessary: if you want to compile
+% documents created with an earlier version of this package or if you use
+% special features. Here's an incomplete list of possible options.
+% \begin{advise}
+% \item Where is a list of all of the options?
+%       \advisespace
+%       In the developer's guide since they were introduced to debug the
+%       package more easily. Read section \ref{uHowTos} on how to get that
+%       guide.
+% \end{advise}
+% \begin{description}
+% \item[\normalfont\texttt{0.21}]\leavevmode
+%
+%       invokes a compatibility mode for compiling documents written for
+%       \packagename{listings} version 0.21.
+%
+% \item[\normalfont\texttt{draft}]\leavevmode
+%
+%       The package prints no stand alone files, but shows the captions and
+%       defines the corresponding labels.
+%       Note that a global |\documentclass|-option \texttt{draft} is
+%       recognized, so you don't need to repeat it as a package option.
+%
+% \item[\normalfont\texttt{final}]\leavevmode\label{uoption:final}
+%
+%       Overwrites a global \texttt{draft} option.
+%
+% \item[\normalfont\texttt{savemem}]\leavevmode
+%
+%       tries to save some of \TeX's memory. If you switch between languages
+%       often, it could also reduce compile time. But all this depends on the
+%       particular document and its listings.
+% \end{description}
+% Note that various experimental features also need explicit loading via
+% options. Read the respective lines in section \ref{rExperimentalFeatures}.
+%
+% \medbreak
+% After package loading it is recommend to load all used dialects of programming
+% languages with the following command. It is faster to load several languages
+% with one command than loading each language on demand.
+% \begin{syntax}
+% \item {\rstyle\icmdname\lstloadlanguages}\marg{comma separated list of languages}
+%
+%       Each language is of the form \oarg{dialect}\meta{language}. Without
+%       the optional \oarg{dialect} the package loads a default dialect. So
+%       write `|[Visual]C++|' if you want Visual \Cpp\ and `|[ISO]C++|' for
+%       ISO \Cpp. Both together can be loaded by the command
+%       |\lstloadlanguages{[Visual]C++,[ISO]C++}|.
+%
+%       Table \ref{uPredefinedLanguages} on page \pageref{uPredefinedLanguages}
+%       shows all defined languages and their dialects.
+% \end{syntax}
+%^^A After or even before language loading, you might want to define default
+%^^A dialects---just to be independent of configuration files.
+%
+%
+% \subsection{The key=value interface}\label{uTheKey=ValueInterface}
+%
+% This package uses the \packagename{keyval} package from the
+% \packagename{graphics} bundle by David Carlisle. Each parameter is
+% controlled by an associated key and a user supplied value. For example,
+% \ikeyname{firstline} is a key and |2| a valid value for this key.
+%
+% The command {\rstyle\icmdname\lstset} gets a comma separated list of
+% ``key|=|value'' pairs. The first list with more than a single entry is on
+% page \pageref{gFirstKey=ValueList}: |firstline=2,lastline=5|.
+% \begin{advise}
+% \item So I can write `|\lstset{firstline=2,lastline=5}|' once for all?
+%       \advisespace
+%       No. `\ikeyname{firstline}' and `\ikeyname{lastline}' belong to a small
+%       set of
+%       keys which are only used on individual listings. However, your command is
+%       not illegal---it has no effect. You have to use these keys inside the
+%       optional argument of the environment or input command.
+% \item What's about a better example of a key|=|value list?
+%       \advisespace
+%       There is one in section \ref{gFigureOutTheAppearance}.
+% \item `|language=[77]Fortran|' does not work inside an optional argument.
+%       \advisespace
+%       You must put braces around the value if a value with optional argument
+%       is used inside an optional argument. In the case here write
+%       `|language={[77]Fortran}|' to select Fortran 77.
+% \item If I use the `\ikeyname{language}' key inside an optional argument, the
+%       language isn't active when I typeset the next listing.
+%       \advisespace
+%       All parameters set via `|\lstset|' keep their values up to the end of
+%       the current environment or group. Afterwards the previous values are
+%       restored. The optional parameters of the two pretty-printing commands
+%       and the `\texttt{lstlisting}' environment take effect on the particular
+%       listing only, i.e.~values are restored immediately. For example, you
+%       can select a main language and change it for special listings.
+% \item \icmdname\lstinline\ has an optional argument?
+%       \advisespace
+%       Yes. And from this fact comes a limitation: you can't use the left
+%       bracket `|[|' as delimiter unless you specify at least an empty
+%       optional argument as in `|\lstinline[][var i:integer;[|'.
+%       If you forget this, you will either get a ``runaway argument'' error
+%       from \TeX, or an error message from the \packagename{keyval} package.
+% \end{advise}
+%
+%
+% \subsection{Programming languages}\label{uProgrammingLanguages}
+%
+% You already know how to activate programming languages---at least Pascal.
+% An optional parameter selects particular dialects of a language. For example,
+% |language=[77]Fortran| selects Fortran 77 and |language=[XSC]Pascal| does the
+% same for Pascal XSC. The general form is
+%    {\rstyle\ikeyname{language}}|=|\oarg{dialect}\meta{language}.
+% If you want to get rid of keyword, comment, and string detection, use
+% |language={}| as an argument to |\lstset| or as optional argument.
+%
+% Table \ref{uPredefinedLanguages} shows all predefined languages and dialects.
+% Use the listed names as \meta{language} and \meta{dialect}, respectively. If
+% no dialect or `empty' is given in the table, just don't specify a dialect.
+% Each underlined dialect is default; it is selected if you leave out
+% the optional argument. The predefined defaults are the newest language
+% versions or standard dialects.

+% \item How can I define default dialects?
+%       \advisespace
+%       Check section \ref{rLanguagesAndStyles} for `\keyname{defaultdialect}'.
+% \item I have C code mixed with assembler lines. Can \packagename{listings}
+%       pretty-print such source code, i.e.~highlight keywords and comments of
+%       both languages?
+%       \advisespace
+%       `\ikeyname{alsolanguage}|=|\oarg{dialect}\meta{language}' selects a
+%       language additionally to the active one. So you only have to write a
+%       language definition for your assembler dialect, which doesn't interfere
+%       with the definition of C, say. Moreover you might want to use the key
+%       `\keyname{classoffset}' described in section \ref{rLanguagesAndStyles}.
+% \item How can I define my own language?
+%       \advisespace
+%       This is discussed in section \ref{rLanguageDefinitions}. And if you
+%       think that other people could benefit by your definition, you might
+%       want to send it to the address in section \ref{uSoftwareLicense}.
+%       Then it will be published under the \LaTeX\ Project Public License.
+% \end{advise}
+% Note that the arguments \meta{language} and \meta{dialect} are case
+% insensitive and that spaces have no effect.
+%
+%
+% \subsection{Special characters}\label{uSpecialCharacters}
+%
+%
+% \paragraph{Tabulators}
+% You might get unexpected output if your sources contain tabulators.
+% The package assumes tabulator stops at columns 9, 17, 25, 33, and so on.
+% This is predefined via |tabsize=8|. If you change the eight to the number
+% $n$, you will get tabulator stops at columns $n+1,2n+1,3n+1,$ and so on.
+% \begin{lstsample}[tabsize]{}{}
+%    \lstset{tabsize=2}
+%    \begin{lstlisting}
+%    123456789
+%    	{ one tabulator }
+%    		{ two tabs }
+%    123		{ 123 + two tabs }
+%    \end{lstlisting}
+% \end{lstsample}
+% For better illustration, the left-hand side uses |tabsize=2| but the verbatim
+% code |tabsize=4|. Note that |\lstset| modifies the values for all following
+% listings in the same environment or group. This is no problem here since the
+% examples are typeset inside minipages. If you want to change settings for a
+% single listing, use the optional argument.
+%
+%
+% \paragraph{Visible tabulators and spaces}
+% One can make spaces and tabulators visible:
+% \begin{lstsample}[showspaces,showtabs,tab]{}{}
+%    \lstset{showspaces=true,
+%            showtabs=true,
+%            tab=\rightarrowfill}
+%    \begin{lstlisting}
+%        for i:=maxint to 0 do
+%        begin
+%    	{ do nothing }
+%        end;
+%    \end{lstlisting}
+% \end{lstsample}
+% If you request \ikeyname{showspaces} but no \ikeyname{showtabs},
+% tabulators are converted to visible spaces.
+% The default definition of \ikeyname{tab} produces a `wide visible space'
+% \lstinline[showtabs]!	!. So you might want to use |$\to$|, |$\dashv$|
+% or something else instead.
+% \begin{advise}
+% \item Some sort of advice: (1) You should really indent lines of source code
+%       to make listings more readable. (2) Don't indent some lines with
+%       spaces and others via tabulators. Changing the tabulator size (of your
+%       editor or pretty-printing tool) completely disturbs the columns.
+%       (3) As a consequence, never share your files with differently tab sized
+%       people!^^A true only if you use tabulators, just :-)
+% \item To make the \LaTeX\ code more readable, I indent the environments'
+%       program listings. How can I remove that indention in the output?
+%       \advisespace
+%       Read `How to gobble characters' in section \ref{uHowTos}.
+% \end{advise}
+%
+%
+% \paragraph{Form feeds}
+% Another special character is a form feed causing an empty line by default.
+% {\rstyle\ikeyname{formfeed}}|=\newpage| would result in a new page every
+% form feed. Please note that such definitions (even the default) might get
+% in conflict with frames.
+%
+%
+% \paragraph{National characters}
+% If you type in such characters directly as characters of codes 128--255 and
+% use them also in listings, let the package know it---or you'll get really
+% funny results. {\rstyle\ikeyname{extendedchars}}|=true| allows and
+% |extendedchars=false| prohibits \packagename{listings} from handling 
+% extended characters in listings. If you use them, you should load
+% \packagename{fontenc}, \packagename{inputenc} and/or
+% any other package which defines the characters.
+% \begin{advise}
+% \item I have problems using \packagename{inputenc} together with
+%       \packagename{listings}.
+%       \advisespace
+%       This could be a compatibility problem. Make a bug report as described
+%       in section \lstref{uTroubleshooting}.
+% \end{advise}
+% The extended characters don't cover Arabic, Chinese, Hebrew, Japanese, and so
+% on---specifically, any encoding which uses multiple bytes per character.
+%
+% Thus, if you use the a package that supports multibyte characters, such as
+% the \packagename{CJK} or \packagename {ucs} packages for Chinese and 
+% UTF-8 characters, you must avoid letting \packagename{listings}
+% process the extended characters.  It is generally best to also specify
+% |extendedchars=false| to avoid having \packagename{listings} get entangled
+% in the other package's extended-character treatment.
+%
+% If you do have a listing contained within a CJK environment, and want to have
+% CJK characters inside the listing, you can place them within a comment that
+% escapes to \LaTeX -- see section \ref{rEscapingToLaTeX} for how to do that.
+% (If the listing is not inside a CJK environment, you can simply put a small
+% CJK environment within the escaped-to-\LaTeX portion of the comment.)
+%
+% Similarly, if you are using UTF-8 extended characters in a listing, they must
+% be placed within an escape to \LaTeX.
+%
+% Also, section \ref{uNationalCharacters} has a few details on how to work with
+% extended characters in the context of $\Lambda$.
+%
+%
+% \subsection{Line numbers}\label{uLineNumbers}
+%
+% You already know the keys \ikeyname{numbers}, \ikeyname{numberstyle},
+% \ikeyname{stepnumber}, and \ikeyname{numbersep} from section
+% \ref{gSeduceToUse}. Here now we deal with continued listings.
+% You have two options to get consistent line numbering across listings.
+%
+% \begin{lstsample}[firstnumber]{\lstset{numbers=left,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{}
+%    \begin{lstlisting}[firstnumber=100]
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%
+%    \end{lstlisting}
+%    And we continue the listing:
+%    \begin{lstlisting}[firstnumber=last]
+%    Write('Case insensitive ');
+%    WritE('Pascal keywords.');
+%    \end{lstlisting}
+% \end{lstsample}
+% In the example, \ikeyname{firstnumber} is initially set to 100; some lines
+% later the value is \texttt{last}, which continues the numbering of the last
+% listing. Note that the empty line at the end of the first part is not printed
+% here, but it counts for line numbering. You should also notice that you can
+% write |\lstset{firstnumber=last}| once and get consecutively numbered code
+% lines---except you specify something different for a particular listing.
+%
+% On the other hand you can use |firstnumber=auto| and name your listings.
+% Listings with identical names (case sensitive!) share a line counter.
+% \begin{lstsample}[name]{\lstset{numbers=left,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{}
+%    \begin{lstlisting}[name=Test]
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%
+%    \end{lstlisting}
+%    And we continue the listing:
+%    \begin{lstlisting}[name=Test]
+%    Write('Case insensitive ');
+%    WritE('Pascal keywords.');
+%    \end{lstlisting}
+% \end{lstsample}
+% The next |Test| listing goes on with line number {\makeatletter\lstno@Test},
+% no matter whether there are other listings in between.
+% \begin{advise}
+% \item Okay. And how can I get decreasing line numbers?
+%       \advisespace
+%       Sorry, what?
+%       \advisespace
+%       Decreasing line numbers as on page \pageref{rDecreasingLabels}.
+%       \advisespace
+%       May I suggest to demonstrate your individuality by other means?
+%       If you differ, you should try a negative `\ikeyname{stepnumber}'
+%       (together with `\ikeyname{firstnumber}').
+% \end{advise}
+%
+% Read section \ref{uHowTos} on how to reference line numbers.
+%
+%
+% \subsection{Layout elements}
+%
+% It's always a good idea to structure the layout by vertical space,
+% horizontal lines, or different type sizes and typefaces. The best to stress
+% whole listings are---not all at once---colours, frames, vertical space, and
+% captions. The latter are also good to refer to listings, of course.
+%
+% \paragraph{Vertical space}
+% The keys {\rstyle\ikeyname{aboveskip}} and {\rstyle\ikeyname{belowskip}}
+% control the vertical space above and below displayed listings. Both keys get
+% a dimension or skip as value and are initialized to |\medskipamount|.
+%
+% \paragraph{Frames}
+% The key \ikeyname{frame} takes the verbose values \keyvalue{none},
+% \keyvalue{leftline}, \keyvalue{topline}, \keyvalue{bottomline},
+% \keyvalue{lines} (top and bottom), \keyvalue{single} for single frames, or
+% \keyvalue{shadowbox}.
+% \begin{lstsample}[frame]{}{}
+%    \begin{lstlisting}[frame=single]
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% \begin{advise}
+% \item The rules aren't aligned.
+%       \advisespace
+%       This could be a bug of this package or a problem with your
+%       \texttt{.dvi} driver. \emph{Before} sending a bug report to the package
+%       author, modify the parameters described in section \ref{rFrames}
+%       heavily. And do this step by step!
+%       For example, begin with `|framerule=10mm|'. If the rules are
+%       misaligned by the same (small) amount as before, the problem does not
+%       come from the rule width. So continue with the next parameter.  Also,
+%       Adobe Acrobat sometimes has single-pixel rounding errors which can 
+%       cause small misalignments at the corners when PDF files are displayed
+%       on screen; these are unfortunately normal.
+% \end{advise}
+% Alternatively you can control the rules at the \texttt{t}op, \texttt{r}ight,
+% \texttt{b}ottom, and \texttt{l}eft directly by using the four initial letters
+% for single rules and their upper case versions for double rules.
+% \begin{lstsample}[frame]{}{}
+%    \begin{lstlisting}[frame=trBL]
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% Note that a corner is drawn if and only if both adjacent rules are requested.
+% You might think that the lines should be drawn up to the edge, but what's
+% about round corners? The key \ikeyname{frameround} must get exactly four
+% characters as value. The first character is attached to the upper right
+% corner and it continues clockwise. `\texttt{t}' as character makes the
+% corresponding corner round.
+% \begin{lstsample}[frameround]{}{}
+%    \lstset{frameround=fttt}
+%    \begin{lstlisting}[frame=trBL]
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% Note that \ikeyname{frameround} has been used together with |\lstset| and thus
+% the value affects all following listings in the same group or environment.
+% Since the listing is inside a \texttt{minipage} here, this is no problem.
+% \begin{advise}
+% \item Don't use frames all the time, and in particular not with short listings.
+%       This would emphasize nothing. Use frames for $10\%$ or even less of
+%       your listings, for your most important ones.
+% \item If you use frames on floating listings, do you really want frames?
+%       \advisespace
+%       No, I want to separate floats from text.
+%       \advisespace
+%       Then it is better to redefine \LaTeX's `|\topfigrule|' and
+%       `|\botfigrule|'. For example, you could write
+%       `|\renewcommand*\topfigrule{\hrule\kern-0.4pt\relax}|' and make the
+%       same definition for |\botfigrule|.
+% \end{advise}
+%
+% \paragraph{Captions}
+% Now we come to \ikeyname{caption} and \ikeyname{label}. You might guess
+% (correctly) that they can be used in the same manner as \LaTeX's |\caption|
+% and |\label| commands, although here it is also possible to have a caption
+% regardless of whether or not the listing is in a float:
+% \begin{lstsample}[caption,label]{\lstset{xleftmargin=.05\linewidth}}{}
+%    \begin{lstlisting}[caption={Useless code},label=useless]
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% Afterwards you could refer to the listing via |\ref{useless}|. By default
+% such a listing gets an entry in the list of listings, which can be printed
+% with the command {\rstyle\icmdname\lstlistoflistings}. The key
+% {\rstyle\ikeyname{nolol}} suppresses an entry for both the environment or
+% the input command. Moreover, you can specify a short caption for the list
+% of listings:
+%    \keyname{caption}|={|\oarg{short}\meta{long}|}|.
+% Note that the whole value is enclosed in braces since an optional value is
+% used in an optional argument.
+%
+% If you don't want the label \texttt{\lstlistingname} plus number, you should
+% use \ikeyname{title}:
+% \begin{lstsample}[title]{\lstset{xleftmargin=.05\linewidth}}{}
+%    \begin{lstlisting}[title={`Caption' without label}]
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% \begin{advise}
+% \item Something goes wrong with `\keyname{title}' in my document: in front of
+%       the title is a delimiter.
+%       \advisespace
+%       The result depends on the document class; some are not compatible.
+%       Contact the package author for a work-around.
+% \end{advise}
+%
+% \paragraph{Colours}
+% One more element. You need the \packagename{color} package and can then
+% request coloured background via
+% \ikeyname{backgroundcolor}|=|\meta{color command}.
+% \begin{advise}
+% \item Great! I love colours.
+%       \advisespace
+%       Fine, yes, really. And I like to remind you of the warning about
+%       striking styles on page \pageref{wStrikingStyles}.
+% \end{advise}
+%\ifcolor
+% \begin{lstxsample}[backgroundcolor]
+%    \lstset{backgroundcolor=\color{yellow}}
+% \end{lstxsample}
+%\else
+% \begin{verbatim}
+%    color package not installed\end{verbatim}
+%\fi
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}[frame=single,
+%                       framerule=0pt]
+%    for i:=maxint to 0 do
+%    begin
+%        j:=square(root(i));
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% The example also shows how to get coloured space around the whole listing:
+% use a frame whose rules have no width.
+%
+%
+% \subsection{Emphasize identifiers}\label{uEmphasizeIdentifiers}
+%
+% Recall the pretty-printing commands and environment. |\lstinline| prints
+% code snippets, |\lstinputlisting| whole files, and \texttt{lstlisting}
+% pieces of code which reside in the \LaTeX\ file. And what are these
+% different `types' of source code good for? Well, it just happens that a
+% sentence contains a code fragment. Whole files are typically included in or
+% as an appendix. Nevertheless some books about programming also include such
+% listings in normal text sections---to increase the number of pages.
+% Nowadays source code should be shipped on disk or CD-ROM and only the main
+% header or interface files should be typeset for reference. So, please, don't
+% misuse the \packagename{listings} package. But let's get back to the topic.
+%
+% Obviously `\texttt{lstlisting} source code' isn't used to make an executable
+% program from. Such source code has some kind of educational purpose or even
+% didactic.
+% \begin{advise}
+% \item What's the difference between educational and didactic?
+%       \advisespace
+%       Something educational can be good or bad, true or false.
+%       Didactic is true by definition.^^A :-)
+% \end{advise}
+% Usually \emph{keywords} are highlighted when the package typesets a piece of
+% source code. This isn't necessary for readers who know the programming
+% language well. The main matter is the presentation of interface, library or
+% other functions or variables. If this is your concern, here come the right
+% keys. Let's say, you want to emphasize the functions |square| and |root|,
+% for example, by underlining them. Then you could do it like this:
+% \begin{lstxsample}[emph,emphstyle]
+%    \lstset{emph={square,root},emphstyle=\underbar}
+% \end{lstxsample}
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    for i:=maxint to 0 do
+%    begin
+%        j:=square(root(i));
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% \begin{advise}
+% \item Note that the list of identifiers |{square,root}| is enclosed in
+%       braces. Otherwise the \packagename{keyval} package would complain
+%       about an undefined key \keyname{root} since the comma finishes the
+%       key=value pair.
+%       Note also that you \emph{must} put braces around the value if you
+%       use an optional argument of a key inside an optional argument of a
+%       pretty-printing command. Though it is not necessary, the following
+%       example uses these braces. They are typically forgotten when they
+%       become necessary,
+% \end{advise}
+%
+% Both keys have an optional \meta{class number} argument for multiple
+% identifier lists:
+%\ifcolor
+% \begin{lstxsample}[emph,emphstyle]
+%    \lstset{emph={square},      emphstyle=\color{red},
+%            emph={[2]root,base},emphstyle={[2]\color{blue}}}
+% \end{lstxsample}
+%\else
+% \begin{lstxsample}[emph,emphstyle]
+%    \lstset{emph={square},      emphstyle=\underbar,
+%            emph={[2]root,base},emphstyle={[2]\fbox}}
+% \end{lstxsample}
+%\fi
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    for i:=maxint to 0 do
+%    begin
+%        j:=square(root(i));
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% \begin{advise}
+% \item What is the maximal \meta{class number}?
+%       \advisespace
+%       $2^{31}-1=2\,147\,483\,647$. But \TeX's memory will exceed before you
+%       can define so many different classes.
+% \end{advise}
+%
+% One final hint: Keep the lists of identifiers disjoint. Never use a keyword
+% in an `emphasize' list or one name in two different lists. Even if your
+% source code is highlighted as expected, there is no guarantee that it is
+% still the case if you change the order of your listings or if you use the
+% next release of this package.
+%
+%
+%\iffalse
+% \subsection{*Listing alignment}\label{uListingAlignment}
+%
+% The examples are typeset with centered \texttt{minipage}s. That's the reason
+% why you can't see that line numbers are printed in the margin. Now we
+% separate the minipage margin and the minipage by a vertical rule:
+% \begin{lstsample}{\lstset{frame=l,framesep=0pt,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{}
+%    Some text before
+%    \begin{lstlisting}
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% The listing is lined up with the normal text. The parameter \ikeyname{xleftmargin}
+% moves the listing to the right (or left if the dimension is negative).
+% \begin{lstsample}{\lstset{frame=l,framesep=0pt,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{}
+%    Some text before
+%    \begin{lstlisting}[xleftmargin=15pt]
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    \end{lstlisting}
+%
+%    \begin{lstlisting}{ }
+%    Write('Insensitive');
+%    WritE('keywords.');
+%    \end{lstlisting}
+% \end{lstsample}
+% Note again that optional arguments change settings for single listings.
+%
+% If you use environments like \texttt{itemize} or \texttt{enumerate}, there
+% is `natural' indention coming from these environments. By default the
+% \packagename{listings} package respects this. But you might use
+% |resetmargins=true| (or |false|) to make your own decision. You can use it
+% together with |xleftmargin|, of course.
+% \begin{advise}
+% \item I get heavy overfull |\hbox|es from some listings.
+%       \advisespace
+%       This comes from long lines in your listings. You have some options
+%       to get rid of the overful |\hbox|es. Firstly I recommend to typeset
+%       listings in smaller fonts than the surrounding text, for example
+%       `|basicstyle=\small|'. Secondly you might want to use the flexible
+%       column format. Thirdly you can increase the line width or set it
+%       explicitly, refer section \ref{rMarginsAndLineShape}.
+%       If all this doesn't help, you might want to change
+%       `\ikeyname{basewidth}', but be careful! The two unknown items are
+%       explained in the next section.
+% \end{advise}
+%
+% You might need to control the vertical position of listings with the
+% \ikeyname{boxpos} key, for example, if you use them in \texttt{minipage} or
+% \texttt{tabular} environments. Here `listings' means \texttt{lstlisting} or
+% |\lstinputlisting|. As the following example shows, you can even place such
+% listings inside paragraphs, but you must force the package to do this by
+% enclosing the listing in |\hbox{| and |}|.
+% \begin{advise}
+% \item Is it good form to use the \TeX-primitive `|\hbox|' in a \LaTeX\ 
+%       document?
+%       \advisespace
+%       No, it's not. But \LaTeX's `|\mbox|' does not work in this example:
+% \end{advise}
+% \begin{lstsample}{}{}
+%    Here are some multi-line listings inside a paragraph.
+%    The `boxpos' key controls their vertical alignment:
+%    \hbox{\begin{lstlisting}[boxpos=c]
+%    center
+%    center
+%    \end{lstlisting}}
+%    \hbox{\begin{lstlisting}[boxpos=b]
+%    bottom baseline
+%    bottom baseline
+%    \end{lstlisting}}
+%    \hbox{\begin{lstlisting}[boxpos=t]
+%    top baseline
+%    top baseline
+%    \end{lstlisting}}
+% \end{lstsample}
+%\fi
+%
+%
+% \subsection{Indexing}\label{uIndexing}
+%
+% Indexing is just like emphasizing identifiers---I mean the usage:
+% \begin{lstxsample}[index]
+%    \lstset{index={square},index={[2]root}}
+% \end{lstxsample}
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    for i:=maxint to 0 do
+%    begin
+%        j:=square(root(i));
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% Of course, you can't see anything here. You will have to look at the index.
+% \begin{advise}
+% \item Why is the `\ikeyname{index}' key able to work with multiple identifier
+%       lists?
+%       \advisespace
+%       This question is strongly related to the `{\rstyle\ikeyname{indexstyle}}'
+%       key. Someone might want to create multiple indexes or want to insert
+%       prefixes like `|constants|', `|functions|', `|keywords|', and so on.
+%       The `\ikeyname{indexstyle}' key works like the other style keys except
+%       that the last token \emph{must} take an argument, namely the
+%       (printable form of the) current identifier.
+%
+%       You can define `|\newcommand\indexkeywords[1]{\index{keywords, #1}}|'
+%       and make similar definitions for constant or function names. Then
+%       `|indexstyle=[1]\indexkeywords|' might meet your purpose. This becomes
+%       easier if you want to create multiple indexes with the
+%       \href{http://www.ctan.org/tex-archive/macros/latex/contrib/camel}
+%       {\packagename{index}} package.
+%       If you have defined appropriate new indexes, it is possible to write
+%       `|indexstyle=\index[keywords]|', for example.
+%
+% \item Let's say, I want to index all keywords. It would be annoying to
+%       type in all the keywords again, specifically if the used programming
+%       language changes frequently.
+%       \advisespace
+%       Just read ahead.
+% \end{advise}
+% The \ikeyname{index} key has in fact two optional arguments. The first is the
+% well-known \meta{class number}, the second is a comma separated list of other
+% keyword classes whose identifiers are indexed. The indexed identifiers then
+% change automatically with the defined keywords---not automagically, it's not
+% an illusion.^^A :-)
+%
+% Eventually you need to know the names of the keyword classes. It's usually
+% the key name followed by a class number, for example, |emph2|, |emph3|,
+% \ldots, |keywords2| or |index5|. But there is no number for the first order
+% classes |keywords|, |emph|, |directives|, and so on.
+% \begin{advise}
+% \item `|index=[keywords]|' does not work.
+%       \advisespace
+%       The package can't guess which optional argument you mean. Hence you
+%       must specify both if you want to use the second one. You should try
+%       `|index=[1][keywords]|'.
+% \end{advise}

+% \subsection{Fixed and flexible columns}\label{uFixedAndFlexibleColumns}
+%
+% The first thing a reader notices---except different styles for keywords,
+% etc.---is the column alignment. Arne John Glenstrup invented the flexible
+% column format in 1997. Since then some efforts were made to develop this
+% branch farther. Currently four column formats are provided: fixed, flexible,
+% space-flexible, and full flexible. Take a close look at the following
+% examples.
+% \begin{center}
+% \lstset{style={},language={}}
+% \def\sample{\begin{lstlisting}^^J WOMEN\ \ are^^A
+%                               ^^J \ \ \ \ \ \ \ MEN^^A
+%                               ^^J WOMEN are^^A
+%                               ^^J better MEN^^J \end{lstlisting}}
+% \begin{tabular}{@{}c@{\qquad\quad}c@{\qquad\quad}c@{\qquad\quad}c@{}}
+% {\rstyle\ikeyname{columns}}|=| & \texttt{fixed} & \texttt{flexible} & \texttt{fullflexible}\\
+%          & (at {\makeatletter\lst@widthfixed})
+%          & (at {\makeatletter\lst@widthflexible})
+%          & (at {\makeatletter\lst@widthflexible})\\
+% \noalign{\medskip}
+%   \lstset{basicstyle=\ttfamily,basewidth=0.51em}\sample
+% & \lstset{columns=fixed}\sample
+% & \lstset{columns=flexible}\sample
+% & \lstset{columns=fullflexible}\sample
+% \end{tabular}
+% \end{center}
+% \begin{advise}
+% \item Why are women better men?
+%       \advisespace
+%       Do you want to philosophize? Well, have I ever said that the
+%       statement ``women are better men'' is true? I can't even remember this
+%       about ``women are men'' \ldots . ^^A ;-)
+% \end{advise}
+% In the abstract one can say: The fixed column format ruins the spacing
+% intended by the font designer, while the flexible formats ruin the column
+% alignment (possibly) intended by the programmer. Common to all is that the
+% input characters are translated into a sequence of basic output units like
+% \begingroup \lstset{gobble=6,xleftmargin=\leftmargini}
+% \makeatletter
+%^^A  Make \fbox around each output unit.
+% \fboxsep=0pt
+% \def\lst@alloverstyle#1{\fbox{\kern-\fboxrule\strut#1}\kern-\fboxrule}
+% \begin{lstlisting}[basewidth=1em]
+%     if x=y then write('align')
+%            else print('align');
+% \end{lstlisting}
+% Now, the fixed format puts $n$ characters into a box of width $n\times{}
+% $`base width', where the base width is {\makeatletter\lst@widthfixed} in the
+% example. The format shrinks and stretches the space between the characters
+% to make them fit the box. As shown in the example, some character strings look
+%    \hbox to 2em{b\hss a\hss d}
+% or
+%    \hbox to 2em{w\hss o\hss r\hss s\hss e},
+% but the output is vertically aligned.
+% \endgroup
+%
+% If you don't need or like this, you should use a flexible format. All
+% characters are typeset at their natural width. In particular, they never
+% overlap. If a word requires more space than reserved, the rest of the line
+% simply moves to the right. The difference between the three formats is that
+% the full flexible format cares about nothing else, while the normal flexible
+% and space-flexible formats try to fix the column alignment if a character
+% string needs less space than `reserved'.  The normal flexible format will
+% insert make-up space to fix the alignment at spaces, before and after
+% identifiers, and before and after sequences of other characters; the 
+% space-flexible format will only insert make-up space by stretching 
+% existing spaces.  In the flexible example above, the two MENs are vertically
+% aligned since some space has been inserted in the fourth line to fix the
+% alignment. In the full flexible format, the two MENs are not aligned.
+%
+% Note that both flexible modes printed the two blanks in the first line as a
+% single blank, but for different reasons: the normal flexible format fixes
+% the column alignment (as would the space-flexible format), and the full
+% flexible format doesn't care about the second space.
+%
+%
+% \section{Advanced techniques}\label{uAdvancedTechniques}
+%
+%
+% \subsection{Style definitions}
+%
+% It is obvious that a pretty-printing tool like this requires some kind of
+% language selection and definition. The first has already been described and
+% the latter is convered by the next section. However, it is very convenient
+% to have the same for printing styles: at a central place of your document
+% they can be modified easily and the changes take effect on all listings.
+%
+% Similar to languages,
+%    {\rstyle\ikeyname{style}}|=|\meta{style name}
+% activates a previously defined style. A definition is as easy:
+%    {\rstyle|\lstdefinestyle|}\marg{style name}\marg{key=value list}.
+% Keys not used in such a definition are untouched by the corresponding style
+% selection, of course. For example, you could write
+% \begin{verbatim}
+%   \lstdefinestyle{numbers}
+%       {numbers=left, stepnumber=1, numberstyle=\tiny, numbersep=10pt}
+%   \lstdefinestyle{nonumbers}
+%       {numbers=none}\end{verbatim}
+% and switch from listings with line numbers to listings without ones and vice
+% versa simply by |style=nonumbers| and |style=numbers|, respectively.
+% \begin{advise}
+% \item You could even write
+%           `|\lstdefinestyle{C++}{language=C++,style=numbers}|'.
+%       Style and language names are independent of each other and so might
+%       coincide. Moreover it is possible to activate other styles.
+%
+% \item It's easy to crash the package using styles. Write
+%       '|\lstdefinestyle{crash}{style=crash}|' and '|\lstset{style=crash}|'.
+%       \TeX's capacity will exceed, sorry [parameter stack size]. Only bad
+%       boys use such recursive calls, but only good girls use this package.
+%       Thus the problem is of minor interest.^^A :-)
+% \end{advise}
+%
+%
+% \subsection{Language definitions}\label{uLanguageDefinitions}
+%
+% These are like style definitions except for an optional dialect name and an
+% optional base language---and, of course, a different command name and
+% specialized keys. In the simple case it's
+%    {\rstyle|\lstdefinelanguage|}\marg{language name}\marg{key=value list}.
+% For many programming languages it is sufficient to specify keywords and
+% standard function names, comments, and strings. Let's look at an example.
+% \begin{lstxsample}[morekeywords,sensitive,morecomment,morestring]
+%    \lstdefinelanguage{rock}
+%      {morekeywords={one,two,three,four,five,six,seven,eight,
+%          nine,ten,eleven,twelve,o,clock,rock,around,the,tonight},
+%       sensitive=false,
+%       morecomment=[l]{//},
+%       morecomment=[s]{/*}{*/},
+%       morestring=[b]",
+%      }
+% \end{lstxsample}
+% \begingroup \csname lst@EndWriteFile\endcsname
+% \bigbreak
+%
+% \noindent
+% There isn't much to say about keywords. They are defined like identifiers
+% you want to emphasize. Additionally you need to specify whether they are
+% case sensitive or not. And yes: you could insert |[2]| in front of the
+% keyword \texttt{one} to define the keywords as `second order' and print them
+% in |keywordstyle={[2]...}|.
+% \begin{advise}
+% \item I get a `\texttt{Missing = inserted for }|\ifnum|' error when I select
+%       my language.
+%       \advisespace
+%       Did you forget the comma after `|keywords={...}|'? And if you encounter
+%       unexpected characters after selecting a language (or style), you have
+%       probably forgotten a different comma or you have given to many
+%       arguments to a key, for example, |morecomment=[l]{--}{!}|.
+% \end{advise}
+%
+% So let's turn to comments and strings. Each value starts with a
+% \emph{mandatory} \oarg{type} argument followed by a changing number of
+% opening and closing delimiters. Note that each delimiter (pair) requires a
+% key=value on its own, even if types are equal. Hence, you'll need to insert
+% \texttt{morestring=[b]'} if single quotes open and close string or character
+% literals in the same way as double quotes do in the example.
+%
+% Eventually you need to know the types and their numbers of delimiters. The
+% reference guide contains full lists, here we discuss only the most common.
+% For strings these are {\rstyle\texttt{b}} and {\rstyle\texttt{d}} with one
+% delimiter each. This delimiter opens and closes the string and inside a
+% string it is either escaped by a \texttt backslash or it is \texttt doubled.
+% The comment type {\rstyle\texttt{l}} requires exactly one delimiter, which
+% starts a comment on any column. This comment goes up to the end of line.
+% The other two most common comment types are {\rstyle\texttt{s}} and
+% {\rstyle\texttt{n}} with two delimiters each. The first delimiter opens a
+% comment which is terminated by the second delimiter. In contrast to the
+% \texttt s-type, \texttt n-type comments can be nested.
+% \begin{lstxsample}[b,d,l,s,n]
+%    \lstset{morecomment=[l]{//},
+%            morecomment=[s]{/*}{*/},
+%            morecomment=[n]{(*}{*)},
+%            morestring=[b]",
+%            morestring=[d]'}
+% \end{lstxsample}
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    "str\"ing "    not a string
+%    'str''ing '    not a string
+%    // comment line
+%    /* comment/**/ not a comment
+%    (* nested (**) still comment
+%       comment  *) not a comment
+%    \end{lstlisting}
+% \end{lstsample}
+% \begin{advise}
+% \item Is it \emph{that} easy?
+%       \advisespace
+%       Almost. There are some troubles you can run into. For example, if
+%       `\texttt{-*}' starts a comment line and `\texttt{-*-}' a string
+%       (unlikely but possible), then you must define the shorter delimiter
+%       first.
+%       Another problem: by default some characters are not allowed inside
+%       keywords, for example `\texttt{-}', `\texttt{:}', `\texttt{.}', and
+%       so on. The reference guide covers this problem by introducing some
+%       more keys, which let you adjust the standard character table
+%       appropriately. But note that white space characters are prohibited
+%       inside keywords.
+% \end{advise}
+% Finally remember that this section is only an introduction to language
+% definitions. There are more keys and possibilities.
+%
+%
+% \subsection{Delimiters}\label{uDelimiters}
+%
+% You already know two special delimiter classes: comments and strings.
+% However, their full syntax hasn't been described so far. For example,
+% \ikeyname{commentstyle} applies to all comments---unless you specify
+% something different. The \emph{optional} \oarg{style} argument follows the
+% \emph{mandatory} \oarg{type} argument.
+%\ifcolor
+% \begin{lstxsample}
+%    \lstset{morecomment=[l][keywordstyle]{//},
+%            morecomment=[s][\color{white}]{/*}{*/}}
+% \end{lstxsample}
+%\else
+% \begin{lstxsample}
+%    \lstset{morecomment=[l][keywordstyle]{//},
+%            morecomment=[s][\underbar]{/*}{*/}}
+% \end{lstxsample}
+%\fi
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    // bold comment line
+%    a single /* comment */
+%    \end{lstlisting}
+% \end{lstsample}
+% As you can see, you have the choice between specifying the style explicitly
+% by \LaTeX\ commands or implicitly by other style keys. But, you're right,
+% some implicitly defined styles have no seperate keys, for example the second
+% order keyword style. Here---and never with the number 1---you just append
+% the order to the base key: \texttt{keywordstyle2}.
+%
+% You ask for an application? Here you are: one can define different printing
+% styles for `subtypes' of a comment, for example
+%\ifcolor
+% \begin{lstxsample}
+%    \lstset{morecomment=[s][\color{blue}]{/*+}{*/},
+%            morecomment=[s][\color{red}]{/*-}{*/}}
+% \end{lstxsample}
+%\else
+% \begin{lstxsample}
+%    \lstset{morecomment=[s][\upshape]{/*+}{*/},
+%            morecomment=[s][\bfseries]{/*-}{*/}}
+% \end{lstxsample}
+%\fi
+% \begin{lstsample}{\lstset{morecomment=[s]{/*}{*/}}}{}
+%    \begin{lstlisting}
+%    /*  normal comment */
+%    /*+    keep cool   */
+%    /*-     danger!    */
+%    \end{lstlisting}
+% \end{lstsample}
+% Here, the comment style is not applied to the second and third line.
+% \begin{advise}
+% \item Please remember that both `extra' comments must be defined \emph{after}
+%       the normal comment, since the delimiter `\texttt{/*}' is a substring of
+%       `\texttt{/*+}' and `\texttt{/*-}'.
+%
+% \item I have another question. Is `\texttt{language=}\meta{different
+%       language}' the only way to remove such additional delimiters?
+%       \advisespace
+%       Call {\rstyle\ikeyname{deletecomment}} and/or
+%       {\rstyle\ikeyname{deletestring}} with the same arguments to remove
+%       the delimiters (but you don't need to provide the optional style
+%       argument).
+% \end{advise}
+% Eventually, you might want to use the prefix \texttt{i} on any comment type.
+% Then the comment is not only invisible, it is completely discarded from the
+% output!
+% \begin{lstxsample}[is]
+%    \lstset{morecomment=[is]{/*}{*/}}
+% \end{lstxsample}
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    begin /* comment */ end
+%    begin/* comment */end
+%    \end{lstlisting}
+% \end{lstsample}
+%
+% Okay, and now for the real challenges. More general delimiters can be defined
+% by the key {\rstyle\ikeyname{moredelim}}. Legal types are {\rstyle\texttt{l}}
+% and {\rstyle\texttt{s}}. These types can be preceded by an \texttt{i}, but
+% this time \emph{only the delimiters} are discarded from the output. This way
+% you can select styles by markers.
+% \begin{lstxsample}
+%    \lstset{moredelim=[is][\ttfamily]{|}{|}}
+% \end{lstxsample}
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    roman |typewriter|
+%    \end{lstlisting}
+% \end{lstsample}
+% You can even let the package detect keywords, comments, strings, and other
+% delimiters inside the contents.
+% \begin{lstxsample}
+%    \lstset{moredelim=*[s][\itshape]{/*}{*/}}
+% \end{lstxsample}
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    /* begin
+%      (* comment *)
+%       ' string ' */
+%    \end{lstlisting}
+% \end{lstsample}
+% Moreover, you can force the styles to be applied cumulatively.
+% \begin{lstxsample}
+%    \lstset{moredelim=**[is][\ttfamily]{|}{|}, % cumulative
+%            moredelim=*[s][\itshape]{/*}{*/}}  % not so
+% \end{lstxsample}
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    /* begin
+%       ' string '
+%       |typewriter| */
+%
+%    | begin
+%     ' string '
+%     /*typewriter*/ |
+%    \end{lstlisting}
+% \end{lstsample}
+% Look carefully at the output and note the differences. The second
+% \texttt{begin} is not printed in bold typewriter type since standard
+% \LaTeX\ has no such font.
+%
+% This suffices for an introduction. Now go and find some more applications.
+%
+%
+% \subsection{Closing and credits}\label{uClosingAndCredits}
+%
+% You've seen a lot of keys but you are far away from knowing all of them.
+% The next step is the real use of the \packagename{listings} package.
+% Please take the following advice. Firstly, look up the known commands and
+% keys in the reference guide to get a notion of the notation there. Secondly,
+% poke around with these keys to learn some other parameters. Then, hopefully,
+% you'll be prepared if you encounter any problems or need some special things.
+%
+% \begin{advise}
+% \item
+% There is one question `you' haven't asked all the last pages: who is to
+% blame. Carsten Heinz wrote the guides, coded the \packagename{listings}
+% package and wrote some language drivers. Brooks Moses currently maintains
+% the package.  Other people defined more languages
+% or contributed their ideas; many others made bug reports, but only the first
+% bug finder is listed.
+%^^A
+%^^A Thanks for error reports (first bug finder only), new programming
+%^^A languages, etc.

+% \part{Reference guide}
+%
+%
+% \section{Main reference}\label{rMainReference}
+%
+% Your first training is completed. Now that you've left the User's guide, the
+% friend telling you what to do has gone. Get more practice and become a
+% journeyman!^^A :-)
+% \begin{advise}
+% \item Actually, the friend hasn't gone. There are still some advices, but
+%       only from time to time.
+% \end{advise}
+%
+%
+% \subsection{How to read the reference}
+%
+% Commands, keys and environments are presented as follows.
+% \begin{syntax}
+% \item[1.0,default,hints] \texttt{command}, \texttt{environment} or
+%       \keyname{key} with \meta{parameters}
+%
+%       This field contains the explanation; here we describe the other fields.
+%
+%       If present, the label in the left margin provides extra information:
+%       `\textit{addon}' indicates additionally introduced functionality,
+%       `\textit{changed}' a modified key, `\textit{data}' a command just
+%       containing data (which is therefore adjustable via |\renewcommand|),
+%       and so on. Some keys and functionality are `\emph{bug}'-marked or
+%       with a \dag-sign. These features might change in future or could be
+%       removed, so use them with care.
+%
+%       If there is verbatim text touching the right margin, it is the
+%       predefined value. Note that some keys default to this value every
+%       listing, namely the keys which can be used on individual listings only.
+% \end{syntax}
+% Regarding the parameters, please keep in mind the following:
+% \begin{enumerate}
+% \item A list always means a comma separated list. You must put braces around
+%       such a list. Otherwise you'll get in trouble with the
+%       \packagename{keyval} package; it complains about an undefined key.
+% \item You must put parameter braces around the whole value of a key if you
+%       use an \oarg{optional argument} of a key inside an optional
+%       \oarg{key=value list}:
+%       |\begin{lstlisting}[caption=|{\rstyle|{|}|[one]two|{\rstyle|}|}|]|.
+% \item Brackets `|[ ]|' usually enclose optional arguments and must be typed
+%       in verbatim. Normal brackets `[ ]' always indicate an optional argument
+%       and must not be typed in. Thus |[*]| must be typed in exactly as is,
+%       but [|*|] just gets |*| if you use this argument.
+% \item A vertical rule indicates an alternative, e.g.~^^A
+%       \meta{\alternative{true,false}} allows either \texttt{true} or
+%       \texttt{false} as arguments.
+% \item If you want to enter one of the special characters |{}#%\|, this
+%       character must be escaped with a backslash. This means that you must
+%       write |\}| for the single character `right brace'---but of course not
+%       for the closing paramater character.
+% \end{enumerate}
+%
+%
+% \subsection{Typesetting listings}\label{rTypesettingListings}
+%
+% \begin{syntax}
+% \item[0.19] \rcmdname\lstset\marg{key=value list}
+%
+%       sets the values of the specified keys, see also section
+%       \ref{uTheKey=ValueInterface}.
+%       The parameters keep their values up to the end of the current group.
+%       In contrast, all optional \meta{key=value list}s below modify the
+%       parameters for single listings only.
+%
+% \item[0.18] \rcmdname\lstinline\oarg{key=value list}\meta{character}\meta{source code}\meta{same character}
+%
+%       works like |\verb| but respects the active language and style. These
+%       listings use flexible columns unless requested differently in the
+%       optional argument, and do not support frames or background colors.
+%       You can write `|\lstinline!var i:integer;!|' and get
+%       `\lstinline!var i:integer;!'.
+%
+%       Since the command first looks ahead for an optional argument, you must
+%       provide at least an empty one if you want to use |[| as
+%       \meta{character}.
+%
+%       \dag\ An experimental implementation has been done to support the
+%       syntax |\lstinline|\oarg{key=value list}\marg{source code}. Try it if
+%       you want and report success and failure. A known limitation is that
+%       inside another argument the last source code token must not be an
+%       explicit space token---and, of course, using a listing inside another
+%       argument is itself experimental, see section \ref{rListingsInsideArguments}.
+%
+%       See also section \ref{rShortInline} for commands to create short analogs
+%       for the |\lstinline| command.
+%
+% \item[0.15] |\begin{|\texttt{\rstyle lstlisting}|}|\oarg{key=value list}
+%
+%       \leavevmode\hspace*{-\leftmargini}|\end{|\texttt{\rstyle lstlisting}|}|
+%
+%       typesets the code in between as a displayed listing.
+%
+%       In contrast to the environment of the \packagename{verbatim} package,
+%       \LaTeX\ code on the same line and after the end of environment is
+%       typeset respectively executed.
+%
+% \item[0.1] \rcmdname\lstinputlisting\oarg{key=value list}\marg{file name}
+%
+%       typesets the stand alone source code file as a displayed listing.
+% \end{syntax}
+%
+%
+% \subsection{Space and placement}
+%
+% \begin{syntax}
+% \item[0.20,floatplacement] \rkeyname{float}|=|[|*|]\meta{subset of \textup{\texttt{tbph}}}\syntaxor\rkeyname{float}
+%
+%       makes sense on individual displayed listings only and lets them float.
+%       The argument controls where \LaTeX\ is \emph{allowed} to put the float:
+%       at the top or bottom of the current/next page, on a separate page, or
+%       here where the listing is.
+%
+%       The optional star can be used to get a double-column float in a
+%       two-column document.
+%
+% \item[0.21,tbp] \rkeyname{floatplacement}|=|\meta{place specifiers}
+%
+%       is used as place specifier if \keyname{float} is used without value.
+%
+% \item[0.21,\medskipamount] \rkeyname{aboveskip}|=|\meta{dimension}
+% \item[0.21,\medskipamount] \rkeyname{belowskip}|=|\meta{dimension}
+%
+%       define the space above and below displayed listings.
+%
+% \item[0.17,0pt,\dag] \rkeyname{lineskip}|=|\meta{dimension}
+%
+%       specifies additional space between lines in listings.
+%
+% \item[0.18,c,\dag] \rkeyname{boxpos}|=|\meta{\alternative{b,c,t}}
+%
+%       Sometimes the \packagename{listings} package puts a |\hbox| around a
+%       listing---or it couldn't be printed or even processed correctly.
+%       The key determines the vertical alignment to the surrounding material:
+%       bottom baseline, centered or top baseline.
+% \end{syntax}
+%
+%
+% \subsection{The printed range}
+%
+% \begin{syntax}
+% \item[0.12,true] \rkeyname{print}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{print}
+%
+%       controls whether an individual displayed listing is typeset. Even if
+%       set false, the respective caption is printed and the label is defined.
+%
+%       Note: If the package is loaded without the \texttt{draft} option, you
+%       can use this key together with |\lstset|. In the other case the key
+%       can be used to typeset particular listings despite using the
+%       \texttt{draft} option.
+%
+% \item[0.1,1] \rkeyname{firstline}|=|\meta{number}
+% \item[0.1,9999999] \rkeyname{lastline}|=|\meta{number}
+%
+%       can be used on individual listings only. They determine the physical
+%       input lines used to print displayed listings.
+%
+% \item[1.2] \rkeyname{linerange}|={|\meta{first1}\texttt-\meta{last1}\texttt,\meta{first2}\texttt-\meta{last2}\texttt, and so on|}|\label{uoption:linerange}
+%
+%       can be used on individual listings only. The given line ranges
+%       of the listing are displayed. The intervals must be sorted and must
+%       not intersect.
+%
+% \item[0.20,false] \rkeyname{showlines}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{showlines}
+%
+%       If true, the package prints empty lines at the end of listings.
+%       Otherwise these lines are dropped (but they count for line numbering).
+%
+% \item[1.0] \rkeyname{emptylines}|=|[|*|]\meta{number}
+%
+%       sets the maximum of empty lines allowed. If there is a block of more
+%       than \meta{number} empty lines, only \meta{number} ones are printed.
+%       Without the optional star, line numbers can be disturbed when blank
+%       lines are omitted; with the star, the lines keep their original
+%       numbers.
+%
+% \item[0.19,0] \rkeyname{gobble}|=|\meta{number}
+%
+%       gobbles \meta{number} characters at the beginning of each
+%       \emph{environment} code line. This key has no effect on \cs{lstinline}
+%       or \cs{lstinputlisting}.
+%
+%       Tabulators expand to \ikeyname{tabsize} spaces before they are gobbled.
+%       Code lines with fewer than \ikeyname{gobble} characters are considered
+%       empty.  Never indent the end of environment by more characters.
+% \end{syntax}
+%
+%
+% \subsection{Languages and styles}\label{rLanguagesAndStyles}
+%
+% Please note that the arguments \meta{language}, \meta{dialect}, and
+% \meta{style name} are case insensitive and that spaces have no effect.
+% \begin{syntax}
+% \item[0.18,{{}}] \rkeyname{style}|=|\meta{style name}
+%
+%       activates the key=value list stored with |\lstdefinestyle|.
+%
+% \item[0.19] \rcmdname\lstdefinestyle\marg{style name}\marg{key=value list}
+%
+%       stores the key=value list.
+%
+% \item[0.17,{{}}] \rkeyname{language}|=|\oarg{dialect}\meta{language}
+%
+%       activates a (dialect of a) programming language. The `empty' default
+%       language detects no keywords, no comments, no strings, and so on; it
+%       may be useful for typesetting plain text.
+%       If \meta{dialect} is not specified, the package chooses the default
+%       dialect, or the empty dialect if there is no default dialect.
+%
+%       Table \ref{uPredefinedLanguages} on page \pageref{uPredefinedLanguages}
+%       lists all languages and dialects provided by \texttt{lstdrvrs.dtx}.
+%       The predefined default dialects are underlined.
+%
+% \item[0.21] \rkeyname{alsolanguage}|=|\oarg{dialect}\meta{language}
+%
+%       activates a (dialect of a) programming language in addition to the
+%       current active one. Note that some language definitions interfere with
+%       each other and are plainly incompatible; for instance, if one is case
+%       sensitive and the other is not.
+%
+%       Take a look at the \ikeyname{classoffset} key in section
+%       \ref{rFigureOutTheAppearance} if you want to highlight the keywords
+%       of the languages differently.
+%
+% \item[0.19] \rkeyname{defaultdialect}|=|\oarg{dialect}\meta{language}
+%
+%       defines \meta{dialect} as default dialect for \meta{language}.
+%       If you have defined a default dialect other than empty, for example
+%       |defaultdialect=[iama]fool|, you can't select the empty dialect, even
+%       not with |language=[]fool|.
+% \end{syntax}
+%
+% Finally, here's a small list of language-specific keys.
+% \begin{syntax}
+% \item[0.19,false,optional] \rkeyname{printpod}|=|\meta{\alternative{true,false}}
+%
+%       prints or drops PODs in Perl.
+%
+% \item[0.20,true,{renamed,optional}] \rkeyname{usekeywordsintag}|=|\meta{\alternative{true,false}}\label{uoption:usekeywordsintag}
+%
+%       The package either use the first order keywords in tags or prints all
+%       identifiers inside |<>| in keyword style.
+%
+% \item[1.1,{{}},optional] \rkeyname{tagstyle}|=|\meta{style}\label{uoption:tagstyle}
+%
+%       determines the style in which tags and their content is printed.
+%
+% \item[1.1,false,optional] \rkeyname{markfirstintag}|=|\meta{style}\label{uoption:markfirstintag}
+%
+%       prints the first name in tags with keyword style.
+%
+% \item[0.20,true,optional] \rkeyname{makemacrouse}|=|\meta{\alternative{true,false}}
+%
+%       Make specific: Macro use of identifiers, which are defined as first
+%       order keywords, also prints the surrounding |$(| and |)| in keyword
+%       style. e.g.~you could get
+%           \textbf{\textdollar(}\textbf{strip} \textdollar(BIBS)\textbf{)}.
+%       If deactivated you get
+%           \textdollar(\textbf{strip} \textdollar(BIBS)).
+% \end{syntax}
+%
+%
+% \subsection{Figure out the appearance}\label{rFigureOutTheAppearance}
+%
+% \begin{syntax}
+% \item[0.18,{{}}] \rkeyname{basicstyle}|=|\meta{basic style}
+%
+%       is selected at the beginning of each listing. You could use
+%       |\footnotesize|, |\small|, |\itshape|, |\ttfamily|, or something like
+%       that. The last token of \meta{basic style} must not read any following
+%       characters.
+%
+% \item[0.18,{{}}] \rkeyname{identifierstyle}|=|\meta{style}
+% \item[0.11,\itshape] \rkeyname{commentstyle}|=|\meta{style}
+% \item[0.12,{{}}] \rkeyname{stringstyle}|=|\meta{style}
+%
+%       determines the style for non-keywords, comments, and strings. The
+%       \emph{last} token can be an one-parameter command like |\textbf| or
+%       |\underbar|.
+%
+% \item[0.11,\bfseries,addon] \rkeyname{keywordstyle}|=|\oarg{number}[\textasteriskcentered]\meta{style}\label{roption:keywordstyle}
+%
+%       is used to print keywords.  The optional \meta{number} argument is the
+%       class number to which the style should be applied.
+%
+%       Add-on: If you use the optional star after the (optional) class number, the
+%       keywords are printed uppercase\,---\,even if a language is case
+%       sensitive and defines lowercase keywords only. Maybe there should also be an
+%       option for lowercase keywords \ldots
+%
+% \item[0.19,keywordstyle,deprecated] \rkeyname{ndkeywordstyle}|=|\meta{style}
+%
+%       is equivalent to |keywordstyle=2|\meta{style}.
+%
+% \item[1.0,0] \rkeyname{classoffset}|=|\meta{number}
+%
+%       is added to all class numbers before the styles, keywords, identifiers,
+%       etc.~are assigned. The example below defines the keywords directly;
+%       you could do it indirectly by selecting two different languages.
+% \end{syntax}
+%\ifcolor
+% \begin{lstxsample}
+%    \lstset{classoffset=0,
+%            morekeywords={one,three,five},keywordstyle=\color{red},
+%            classoffset=1,
+%            morekeywords={two,four,six},keywordstyle=\color{blue},
+%            classoffset=0}% restore default
+% \end{lstxsample}
+%\else
+% \begin{lstxsample}
+%    \lstset{classoffset=0,
+%            morekeywords={one,three,five},keywordstyle=\itshape,
+%            classoffset=1,
+%            morekeywords={two,four,six},keywordstyle=\bfseries},
+%            classoffset=0}% restore default
+% \end{lstxsample}
+%\fi
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}
+%    one two three
+%    four five six
+%    \end{lstlisting}
+% \end{lstsample}
+%
+% \begin{syntax}
+% \item[0.20,keywordstyle,{addon,bug,optional}] \rkeyname{texcsstyle}|=|[|*|]\oarg{class number}\meta{style}\label{roption:texcsstyle}
+% \item[0.20,keywordstyle,optional] \rkeyname{directivestyle}|=|\meta{style}
+%
+%       determine the style of \TeX\ control sequences and directives.
+%       Note that these keys are present only if you've chosen an appropriate
+%       language.
+%
+%       The optional star of |texcsstyle| also highlights the backslash in
+%       front of the control sequence name. Note that this option is set for
+%       all |texcs| lists.
+%
+%       Bug: \texttt{texcs\ldots} interferes with other keyword lists. If, for
+%       example, \texttt{emph} contains the word \texttt{foo}, then the control
+%       sequence |\foo| will show up in \texttt{emphstyle}.
+%
+% \item[0.21] \rkeyname{emph}|=|\oarg{number}\marg{identifier list}
+% \item[0.21] \rkeyname{moreemph}|=|\oarg{number}\marg{identifier list}
+% \item[0.21] \rkeyname{deleteemph}|=|\oarg{number}\marg{identifier list}
+% \item[0.21] \rkeyname{emphstyle}|=|\oarg{number}\marg{style}
+%
+%       respectively define, add or remove the \meta{identifier list} from
+%       `emphasize class \meta{number}', or define the style for that class.
+%       If you don't give an optional argument, the package assumes
+%       \meta{number}$\,=1$.
+%
+%       These keys are described more detailed in section

+%
+%       define, add, or remove user supplied delimiters.  (Note that this does
+%       not affect strings or comments.)
+%
+%       In the first two cases \meta{style} is used to print the delimited
+%       code (and the delimiters). Here, \meta{style} could be something like
+%       |\bfseries| or |\itshape|, or it could refer to other styles via
+%       \texttt{keywordstyle}, \texttt{keywordstyle2}, \texttt{emphstyle},
+%       etc.
+%
+%       Supported types are \texttt{l} and \texttt{s}, see the comment keys in
+%       section \ref{uLanguageDefinitions} for an explanation. If you use the
+%       prefix \texttt i, i.e.~\texttt{il} or \texttt{is}, the delimiters are
+%       not printed, which is some kind of invisibility.
+%
+%       If you use one optional star, the package will detect keywords,
+%       comments, and strings inside the delimited code. With both optional
+%       stars, aditionally the style is applied cumulatively; see section
+%       \ref{uDelimiters}.

+%
+% \subsection{Getting all characters right}
+%
+% \begin{syntax}
+% \item[0.18,true] \rkeyname{extendedchars}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{extendedchars}
+%
+%       allows or prohibits extended characters in listings, that means
+%       (national) characters of codes 128--255. If you use extended
+%       characters, you should load \packagename{fontenc} and/or
+%       \packagename{inputenc}, for example.
+%
+% \item[1.0,{{}}] \rkeyname{inputencoding}|=|\meta{encoding}
+%
+%       determines the input encoding. The usage of this key requires the
+%       \packagename{inputenc} package; nothing happens if it's not loaded.
+%
+% \item[1.1,false] \rkeyname{upquote}|=|\meta{\alternative{true,false}}\label{uoption:upquote}
+%
+%       determines whether the left and right quote are printed |`'| or
+%       \texttt{\textasciigrave\textquotesingle}.
+%       This key requires the \packagename{textcomp} package if true.
+%
+% \item[0.12,8] \rkeyname{tabsize}|=|\meta{number}
+%
+%       sets tabulator stops at columns $\meta{number}+1$, $2\cdot\meta{number}+1$, $3\cdot\meta{number}+1$, and so on.
+%       Each tabulator in a listing moves the current column to the next
+%       tabulator stop.
+%
+% \item[0.20,false] \rkeyname{showtabs}|=|\meta{\alternative{true,false}}
+%
+%       make tabulators visible or invisible. A visible tabulator looks like
+%       \lstinline[showtabs]!	!, but that can be changed. If you choose
+%       invisible tabulators but visible spaces, tabulators are converted to
+%       an appropriate number of spaces.
+%
+% \item[0.20] \rkeyname{tab}|=|\meta{tokens}
+%
+%       \meta{tokens} is used to print a visible tabulator. You might want to use |$\to$|, |$\mapsto$|, |$\dashv$| or something like that instead of the strange default definition.
+%
+% \item[0.20,false] \rkeyname{showspaces}|=|\meta{\alternative{true,false}}
+%
+%       lets all blank spaces appear {\textvisiblespace} or as blank spaces.
+%
+% \item[0.12,true] \rkeyname{showstringspaces}|=|\meta{\alternative{true,false}}
+%
+%       lets blank spaces in strings appear {\textvisiblespace} or as blank
+%       spaces.
+%
+% \item[0.19,\bigbreak] \rkeyname{formfeed}|=|\meta{tokens}
+%
+%       Whenever a listing contains a form feed, \meta{tokens} is executed.
+% \end{syntax}
+%
+%
+% \subsection{Line numbers}\label{rLineNumbers}
+%
+% \begin{syntax}
+% \item[1.0,none] \rkeyname{numbers}|=|\meta{\alternative{none,left,right}}
+%
+%       makes the package either print no line numbers, or put them on the
+%       left or the right side of a listing.
+%
+% \item[0.16,1] \rkeyname{stepnumber}|=|\meta{number}
+%
+%       All lines with ``line number $\equiv 0$ modulo \meta{number}'' get a
+%       line number. 
+%       If you turn line numbers on and off with \keyname{numbers}, the
+%       parameter \keyname{stepnumber} will keep its value. Alternatively you
+%       can turn them off via |stepnumber=0| and on with a nonzero number, and
+%       keep the value of \keyname{numbers}.
+%
+% \item[1.1,false] \rkeyname{numberfirstline}|=|\meta{\alternative{true,false}}\label{uoption:numberfirstline}
+%
+%       The first line of each listing gets numbered (if numbers are on at all)
+%       even if the line number is not divisible by \keyname{stepnumber}.
+%
+% \item[0.16,{{}}] \rkeyname{numberstyle}|=|\meta{style}
+%
+%       determines the font and size of the numbers.
+%
+% \item[0.19,10pt] \rkeyname{numbersep}|=|\meta{dimension}
+%
+%       is the distance between number and listing.
+%
+% \item[1.0,true] \rkeyname{numberblanklines}|=|\meta{\alternative{true,false}}
+%
+%       If this is set to false, blank lines get no printed line number.
+%
+% \item[0.20,auto] \rkeyname{firstnumber}|=|\meta{\alternative{auto,last,\normalfont\meta{number}}}
+%
+%       \texttt{auto} lets the package choose the first number: a new listing
+%       starts with number one, a named listing continues the most recent
+%       same-named listing (see below), and a stand alone file begins with
+%       the number corresponding to the first input line.
+%
+%       \texttt{last} continues the numbering of the most recent listing and
+%       \meta{number} sets it to the number.
+%
+% \item[1.0] \rkeyname{name}|=|\meta{name}
+%
+%       names a listing. Displayed environment-listings with the same name
+%       share a line counter if |firstnumber=auto| is in effect.
+%
+% \item[0.20,\arabic{lstnumber},data] \rcmdname\thelstnumber
+%
+%       prints the lines' numbers.
+% \end{syntax}
+% We show an example on how to redefine |\thelstnumber|. But if you test it,
+% you won't get the result shown on the left.
+% \begin{lstxsample}
+%    \renewcommand*\thelstnumber{\oldstylenums{\the\value{lstnumber}}}
+% \end{lstxsample}
+% \begin{lstsample}{\lstset{stepnumber=-1}\label{rDecreasingLabels}}{}

+%    begin { empty lines }
+%
+%
+%
+%
+%
+%
+%    end; { empty lines }
+%    \end{lstlisting}
+% \end{lstsample}
+%
+% \begin{advise}
+% \item
+% The example shows a sequence $n,n+1,\ldots,n+7$ of 8 three-digit figures such that the sequence contains each digit $0,1,\ldots,9$.
+% But 8 is not minimal with that property.
+% Find the minimal number and prove that it is minimal.
+% How many minimal sequences do exist?
+%
+% Now look at the generalized problem:
+% Let $k\in\{1,\ldots,10\}$ be given.
+% Find the minimal number $m\in\{1,\ldots,10\}$ such that there is a sequence $n,{n+1},\ldots,\allowbreak{n+m-1}$ of $m$ $k$-digit figures which contains each digit $\{0,\ldots,9\}$.
+% Prove that the number is minimal.
+% How many minimal sequences do exist?
+%
+% If you solve this problem with a computer, write a \TeX\ program!
+% \end{advise}
+%
+%
+% \subsection{Captions}
+%
+% In despite of \LaTeX\ standard behaviour, captions and floats are independent
+% from each other here; you can use captions with non-floating listings.
+% \begin{syntax}
+% \item[0.21] \rkeyname{title}|=|\meta{title text}
+%
+%       is used for a title without any numbering or label.
+%
+% \item[0.20] \rkeyname{caption}|={|\oarg{short}\meta{caption text}|}|
+%
+%       The caption is made of \cs{lstlistingname} followed by a running
+%       number, a seperator, and \meta{caption text}. Either the caption text
+%       or, if present, \meta{short} will be used for the list of listings.
+%
+% \item[0.21] \rkeyname{label}|=|\meta{name}
+%
+%       makes a listing referable via |\ref|\marg{name}.
+%
+% \item[0.16] \rcmdname\lstlistoflistings
+%
+%       prints a list of listings. Each entry is with descending priority
+%       either the short caption, the caption, the file name or the name of the
+%       listing, see also the key \keyname{name} in section \ref{rLineNumbers}.
+%
+% \item[1.0] \rkeyname{nolol}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{nolol}
+%
+%       If true, the listing does not make it into the list of listings.
+%
+% \item[0.16,Listings,data] \rcmdname\lstlistlistingname
+%
+%       The header name for the list of listings.
+%
+% \item[0.20,Listing,data] \rcmdname\lstlistingname
+%
+%       The caption label for listings.
+%
+% \item[0.20,\arabic{lstlisting},data] \rcmdname\thelstlisting
+%
+%       prints the running number of the caption.
+%
+% \item[1.4,true] \rkeyname{numberbychapter}|=|\meta{\alternative{true,false}}
+%
+%       If true, and |\thechapter| exists, listings are numbered by chapter.
+%       Otherwise, they are numbered sequentially from the beginning of the
+%       document.  This key can only be used before |\begin{document}|.
+%
+% \item[0.19] \rcmdname\lstname
+%
+%       prints the name of the current listing which is either the file name or
+%       the name defined by the \keyname{name} key. This command can be used to
+%       define a caption or title template, for example by
+%       |\lstset{caption=\lstname}|.
+%
+% \item[0.20,t] \rkeyname{captionpos}|=|\meta{subset of \textup{\texttt{tb}}}
+%
+%       specifies the positions of the caption: top and/or bottom of the
+%       listing.
+%
+% \item[0.20,\smallskipamount] \rkeyname{abovecaptionskip}|=|\meta{dimension}
+% \item[0.20,\smallskipamount] \rkeyname{belowcaptionskip}|=|\meta{dimension}
+%
+%       is the vertical space respectively above or below each caption.
+% \end{syntax}
+%
+%
+% \subsection{Margins and line shape}\label{rMarginsAndLineShape}
+%
+% \begin{syntax}
+% \item[0.21,\linewidth] \rkeyname{linewidth}|=|\meta{dimension}
+%
+%       defines the base line width for listings. The following three keys are
+%       taken into account additionally.
+%
+% \item[0.19,0pt] \rkeyname{xleftmargin}|=|\meta{dimension}
+% \item[1.0,0pt] \rkeyname{xrightmargin}|=|\meta{dimension}
+%
+%       The dimensions are used as extra margins on the left and right. Line
+%       numbers and frames are both moved accordingly.
+%
+% \item[0.19,false] \rkeyname{resetmargins}|=|\meta{\alternative{true,false}}
+%
+%       If true, indention from list environments like \texttt{enumerate} or
+%       \texttt{itemize} is reset, i.e.~not used.
+%
+% \item[0.20,false] \rkeyname{breaklines}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{breaklines}
+%
+%       activates or deactivates automatic line breaking of long lines.
+%
+% \item[1.2,false] \rkeyname{breakatwhitespace}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{breakatwhitespace}\label{uoption:breakatwhitespace}
+%
+%       If true, it allows line breaks only at white space.
+%
+% \item[0.20,{{}}] \rkeyname{prebreak}|=|\meta{tokens}
+% \item[0.20,{{}}] \rkeyname{postbreak}|=|\meta{tokens}
+%
+%       \meta{tokens} appear at the end of the current line respectively at the beginning of the next (broken part of the) line.
+%
+%       You must not use dynamic space (in particular spaces) since internally we use |\discretionary|.
+%       However |\space| is redefined to be used inside \meta{tokens}.
+%
+% \item[0.20,20pt] \rkeyname{breakindent}|=|\meta{dimension}
+%
+%       is the indention of the second, third, \ldots\ line of broken lines.
+%
+% \item[0.20,true] \rkeyname{breakautoindent}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{breakautoindent}
+%
+%       activates or deactivates automatic indention of broken lines. This
+%       indention is used additionally to \ikeyname{breakindent}, see the
+%       example below.
+%       Visible spaces or visible tabulators might set this auto
+%       indention to zero.
+% \end{syntax}
+% In the following example we use tabulators to create long lines, but the
+% verbatim part uses |tabsize=1|.
+% \begin{lstxsample}
+%    \lstset{postbreak=\space, breakindent=5pt, breaklines}
+% \end{lstxsample}
+% \begin{lstsample}{\lstset{string=[d]",tabsize=6}}{\lstset{tabsize=1}\hfuzz=1in}
+%    \begin{lstlisting}
+%    		"A long string is broken!"
+%    			"Another long line."
+%    \end{lstlisting}
+%
+%    \begin{lstlisting}[breakautoindent
+%                                 =false]
+%    		{ Now auto indention is off. }
+%    \end{lstlisting}
+% \end{lstsample}
+%
+%
+% \subsection{Frames}\label{rFrames}
+%
+% \begin{syntax}
+% \item[1.0,none] \rkeyname{frame}|=|\meta{\alternative{none,leftline,topline,bottomline,lines,single,shadowbox}}
+%
+%       draws either no frame, a single line on the left, at the top, at the
+%       bottom, at the top and bottom, a whole single frame, or a shadowbox.
+%
+%       Note that \packagename{fancyvrb} supports the same frame types except
+%       \texttt{shadowbox}. The shadow color is \keyname{rulesepcolor}, see
+%       below.
+%
+% \item[0.19,{{}}] \rkeyname{frame}|=|\meta{subset of \textup{\texttt{trblTRBL}}}
+%
+%		The characters \texttt{trblTRBL} designate lines at the top and
+%       bottom of a listing and to lines on the right and left. Upper case
+%       characters are used to draw double rules. So |frame=tlrb| draws a
+%       single frame and |frame=TL| double lines at the top and on the left.
+%
+%       Note that frames usually reside outside the listing's space.
+%
+% \item[0.20,ffff] \rkeyname{frameround}|=|\meta{\alternative{t,f}}\meta{\alternative{t,f}}\meta{\alternative{t,f}}\meta{\alternative{t,f}}
+%
+%       The four letters designate the top right, bottom right, bottom
+%       left and top left corner. In this order. \texttt{t} makes the
+%       according corner round. If you use round corners, the rule width is
+%       controlled via |\thinlines| and |\thicklines|.
+%
+%       Note: The size of the quarter circles depends on \keyname{framesep}
+%       and is independent of the extra margins of a frame. The size is
+%       possibly adjusted to fit \LaTeX's circle sizes.
+%
+% \item[0.19,3pt] \rkeyname{framesep}|=|\meta{dimension}
+% \item[0.19,2pt] \rkeyname{rulesep}|=|\meta{dimension}
+%
+%		control the space between frame and listing and between double rules.
+%
+% \item[0.19,0.4pt] \rkeyname{framerule}|=|\meta{dimension}
+%
+%		controls the width of the rules.
+%
+% \item[1.0,0pt] \rkeyname{framexleftmargin}|=|\meta{dimension}
+% \item[1.0,0pt] \rkeyname{framexrightmargin}|=|\meta{dimension}
+% \item[1.0,0pt] \rkeyname{framextopmargin}|=|\meta{dimension}
+% \item[1.0,0pt] \rkeyname{framexbottommargin}|=|\meta{dimension}
+%
+%       are the dimensions which are used additionally to \keyname{framesep}
+%       to make up the margin of a frame.
+%
+% \item[0.21] \rkeyname{backgroundcolor}|=|\meta{color command}
+% \item[0.21] \rkeyname{rulecolor}|=|\meta{color command}
+% \item[1.0] \rkeyname{fillcolor}|=|\meta{color command}
+% \item[1.0] \rkeyname{rulesepcolor}|=|\meta{color command}
+%
+%       specify the colour of the background, the rules, the space between
+%       `text box' and first rule, and of the space between two rules,
+%       respectively.
+%       Note that the value requires a |\color| command, for example
+%       \keyname{rulecolor}|=\color{blue}|.
+% \end{syntax}
+% \ikeyname{frame} does not work with |fancyvrb=true| or when the package
+% internally makes a |\hbox| around the listing! And there are certainly more
+% problems with other commands; please take the time to make a (bug) report.
+%\ifcolor
+% \begin{lstxsample}

+%    begin
+%        { do nothing }
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+%
+% Note here the use of |framexleftmargin| to include the line numbers inside
+% the frame.
+%
+% Do you want exotic frames? Try the following key if you want, for example,
+% \begin{lstsample}{\lstset{frameshape={RYRYNYYYY}{yny}{yny}{RYRYNYYYY}}}{}
+%    \begin{lstlisting}
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    \end{lstlisting}
+% \end{lstsample}
+% \begin{syntax}
+% \item[0.20,,\dag] \rkeyname{frameshape}|=|\marg{top shape}\marg{left shape}\marg{right shape}\marg{bottom shape}
+%
+%       gives you full control over the drawn frame parts.
+%       The arguments are not case sensitive.
+%
+%       Both \meta{left shape} and \meta{right shape} are `left-to-right'
+%       \alternative{y,n} character sequences (or empty). Each |y| lets the
+%       package draw a rule, otherwise the rule is blank. These vertical rules
+%       are drawn `left-to-right' according to the specified shapes.
+%       The example above uses |yny|.
+%
+%       \meta{top shape} and \meta{bottom shape} are `left-rule-right'
+%       sequences (or empty). The first `left-rule-right' sequence is attached
+%       to the most inner rule, the second to the next, and so on.
+%       Each sequence has three characters: `rule' is either |y| or |n|;
+%       `left' and `right' are |y|, |n| or |r| (which makes a corner round).
+%       The example uses |RYRYNYYYY| for both shapes:
+%       |RYR| describes the most inner (top and bottom) frame shape, |YNY|
+%       the middle, and |YYY| the most outer.
+% \end{syntax}
+% To summarize, the example above used
+% \begin{verbatim}
+%    \lstset{frameshape={RYRYNYYYY}{yny}{yny}{RYRYNYYYY}}\end{verbatim}
+% Note that you are not resticted to two or three levels.
+% However you'll get in trouble if you use round corners when they are too big.
+%
+%
+% \subsection{Indexing}
+%
+% \begin{syntax}
+% \item[0.19] \rkeyname{index}|=|\oarg{number}\oarg{keyword classes}\marg{identifiers}
+% \item[0.21] \rkeyname{moreindex}|=|\oarg{number}\oarg{keyword classes}\marg{identifiers}
+% \item[0.21] \rkeyname{deleteindex}|=|\oarg{number}\oarg{keyword classes}\marg{identifiers}
+%
+%       define, add and remove \meta{identifiers} and \meta{keyword classes}
+%       from the index class list \meta{number}. If you don't specify the
+%       optional number, the package assumes \meta{number} $=1$.
+%
+%		Each appearance of the explicitly given identifiers and each appearance
+%       of the identifiers of the specified \meta{keyword classes} is indexed.
+%       For example, you could write |index=[1][keywords]| to index all
+%       keywords. Note that |[1]| is required here---otherwise we couldn't use
+%       the second optional argument.
+%
+% \item[0.19,\lstindexmacro] \rkeyname{indexstyle}|=|\oarg{number}\meta{tokens \textup(one-parameter command\textup)}
+%
+%       \meta{tokens} actually indexes the identifiers for the list
+%       \meta{number}. In contrast to the style keys, \meta{tokens}
+%       \emph{must} read exactly one parameter, namely the identifier.
+%       Default definition is\icmdname{\lstindexmacro}\vspace*{-\itemsep}
+% \begin{verbatim}
+%    \newcommand\lstindexmacro[1]{\index{{\ttfamily#1}}}\end{verbatim}
+%       \vspace*{-\itemsep}which you shouldn't modify.
+%       Define your own indexing commands and use them as argument to this key.
+% \end{syntax}
+% Section \ref{uIndexing} describes this feature in detail.
+%
+%
+% \subsection{Column alignment}\label{rColumnAlignment}
+%
+% \begin{syntax}
+% \item[1.0,{[c]fixed}] \rkeyname{columns}|=|\oarg{\alternative{c,l,r}}\meta{alignment}
+%
+%       selects the column alignment.  The \meta{alignment} can be |fixed|,
+%       |flexible|, |spaceflexible|, or |fullflexible|; see section
+%       \ref{uFixedAndFlexibleColumns} for details.
+%
+%       The optional |c|, |l|, or |r| controls the horizontal orientation of
+%       smallest output units (keywords, identifiers, etc.). The arguments work
+%       as follows, where vertical bars visualize the effect:
+%           $\vert$\lstinline[columns={[c]fixed}]!listing!$\vert$,
+%           $\vert$\lstinline[columns={[l]fixed}]!listing!$\vert$, and
+%           $\vert$\lstinline[columns={[r]fixed}]!listing!$\vert$
+%       in fixed column mode,
+%           $\vert$\lstinline[columns={[c]flexible}]!listing!$\vert$,
+%           $\vert$\lstinline[columns={[l]flexible}]!listing!$\vert$, and
+%           $\vert$\lstinline[columns={[r]flexible}]!listing!$\vert$
+%       with flexible columns, and
+%           $\vert$\lstinline[columns={[c]fullflexible}]!listing!$\vert$,
+%           $\vert$\lstinline[columns={[l]fullflexible}]!listing!$\vert$, and
+%           $\vert$\lstinline[columns={[r]fullflexible}]!listing!$\vert$
+%       with space-flexible or full flexible columns (which ignore the
+%       optional argument, since they do not add extra space around
+%       printable characters).
+%
+% \item[0.18,false] \rkeyname{flexiblecolumns}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{flexiblecolumns}
+%
+%       selects the most recently selected flexible or fixed column format,
+%       refer to section \ref{uFixedAndFlexibleColumns}.
+%
+% \item[0.21,false,\dag] \rkeyname{keepspaces}|=|\meta{\alternative{true,false}}
+%
+%       |keepspaces=true| tells the package not to drop spaces to fix column
+%       alignment and always converts tabulators to spaces.

+% \item[0.18,{{0.6em,0.45em}}] \rkeyname{basewidth}|={|\meta{fixed}|,|\meta{flexible mode}|}|
+%
+%       sets the width of a single character box for fixed and flexible column
+%       mode (both to the same value or individually).
+%
+% \item[0.20,false] \rkeyname{fontadjust}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{fontadjust}
+%
+%       If true the package adjusts the base width every font selection.
+%       This makes sense only if \ikeyname{basewidth} is given in font specific
+%       units like `em' or `ex'---otherwise this boolean has no effect.
+%
+%       After loading the package, it doesn't adjust the width every font
+%       selection: it looks at \ikeyname{basewidth} each listing and uses the
+%       value for the whole listing. This is possibly inadequate if the style
+%       keys in section \ref{rFigureOutTheAppearance} make heavy font size
+%       changes, see the example below.
+%
+%       Note that this key might disturb the column alignment and might have an
+%       effect on the keywords' appearance!

+% \subsection{Escaping to \LaTeX}\label{rEscapingToLaTeX}
+%
+% \textbf{Note:} {\itshape Any escape to \LaTeX\ may disturb the column
+% alignment since the package can't control the spacing there.}
+% \begin{syntax}
+% \item[0.18,false] \rkeyname{texcl}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{texcl}
+%
+%       activates or deactivates \LaTeX\ comment lines. If activated, comment
+%       line delimiters are printed as usual, but the comment line text (up to
+%       the end of line) is read as \LaTeX\ code and typeset in comment style.
+% \end{syntax}
+% The example uses \Cpp\ comment lines (but doesn't say how to define them).
+% Without |\upshape| we would get \textit{calculate} since the comment style
+% is |\itshape|.
+% \begin{lstsample}{\lstset{morecomment=[l]//}}{}
+%    \begin{lstlisting}[texcl]
+%    // \upshape calculate $a_{ij}$
+%      A[i][j] = A[j][j]/A[i][j];
+%    \end{lstlisting}
+% \end{lstsample}
+%
+% \begin{syntax}
+% \item[0.19,false] \rkeyname{mathescape}|=|\meta{\alternative{true,false}}
+%
+%       activates or deactivates special behaviour of the dollar sign.
+%       If activated a dollar sign acts as \TeX's text math shift.
+%
+%       This key is useful if you want to typeset formulas in listings.
+%
+% \item[0.19,{{}}] \rkeyname{escapechar}|=|\meta{character}\syntaxor\rkeyname{escapechar}|={}|
+%
+%       If not empty the given character escapes the user to \LaTeX: all code
+%       between two such characters is interpreted as \LaTeX\ code. Note that
+%       \TeX's special characters must be entered with a preceding backslash,
+%       e.g.~|escapechar=\%|.
+%
+% \item[0.20,{{}}] \rkeyname{escapeinside}|=|\meta{character}\meta{character}\syntaxor\rkeyname{escapeinside}|={}|
+%
+%       Is a generalization of \ikeyname{escapechar}. If the value is not
+%       empty, the package escapes to \LaTeX\ between the first and second
+%       character.
+%
+% \item[0.20,{{}}] \rkeyname{escapebegin}|=|\meta{tokens}
+% \item[0.20,{{}}] \rkeyname{escapeend}|=|\meta{tokens}
+%
+%       The tokens are executed at the beginning respectively at the end of
+%       each escape, in particular for \ikeyname{texcl}.
+%       See section \ref{uNationalCharacters} for an application.
+% \end{syntax}
+%
+% \begin{lstsample}{\lstset{morecomment=[l]//}}{}
+%    \begin{lstlisting}[mathescape]
+%    // calculate $a_{ij}$
+%      $a_{ij} = a_{jj}/a_{ij}$;
+%    \end{lstlisting}
+% \end{lstsample}
+%
+% \begin{lstsample}{\lstset{morecomment=[l]//}}{}
+%    \begin{lstlisting}[escapechar=\%]
+%    // calc%ulate $a_{ij}$%
+%      %$a_{ij} = a_{jj}/a_{ij}$%;
+%    \end{lstlisting}
+% \end{lstsample}
+%
+% \begin{lstsample}{\lstset{morecomment=[l]//}}{}
+%    \lstset{escapeinside=`'}
+%    \begin{lstlisting}
+%    // calc`ulate $a_{ij}$'
+%      `$a_{ij} = a_{jj}/a_{ij}$';
+%    \end{lstlisting}
+% \end{lstsample}
+% In the first example the comment line up to $a_{ij}$ has been typeset by the
+% \packagename{listings} package in comment style. The $a_{ij}$ itself is
+% typeset in `\TeX\ math mode' without comment style. About half of the
+% comment line of the second example has been typeset by this package, and
+% the rest is in `\LaTeX\ mode'.
+%
+% To avoid problems with the current and future version of this package:
+% \begin{enumerate}
+% \item Don't use any commands of the \packagename{listings} package when you
+%       have escaped to \LaTeX.
+% \item Any environment must start and end inside the same escape.
+% \item You might use |\def|, |\edef|, etc., but do not assume that the
+%       definitions are present later, unless they are |\global|.
+% \item |\if \else \fi|, groups, math shifts |$| and |$$|, \ldots\ must be
+%       balanced within each escape.
+% \item \ldots
+% \end{enumerate}
+% Expand that list yourself and mail me about new items.
+%
+%
+% \subsection{Interface to \textsf{fancyvrb}}
+%
+% The \packagename{fancyvrb} package---fancy verbatims---from Timothy van Zandt
+% provides macros for reading, writing and typesetting verbatim code. It has
+% some remarkable features the \packagename{listings} package doesn't have.
+% (Some are possible, but you must find somebody who will implement them |;-)|.
+% \begin{syntax}
+% \item[0.19] \rkeyname{fancyvrb}|=|\meta{\alternative{true,false}}
+%
+%       activates or deactivates the interface. If active, verbatim code is
+%       read by \packagename{fancyvrb} but typeset by \packagename{listings},
+%       i.e.~with emphasized keywords, strings, comments, and so on.
+%       Internally we use a very special definition of |\FancyVerbFormatLine|.
+%
+%       This interface works with |Verbatim|, |BVerbatim| and |LVerbatim|.
+%       But you shouldn't use \packagename{fancyvrb}'s \keyname{defineactive}.
+%       (As far as I can see it doesn't matter since it does nothing at all,
+%       but for safety \ldots .)
+%       If \packagename{fancyvrb} and \packagename{listings} provide similar
+%       functionality, you should use \packagename{fancyvrb}'s.
+%
+% \item[1.1,{\overlay 1}] \rkeyname{fvcmdparams}|=|\meta{command$_1$}\meta{number$_1$}\ldots\label{uoption:fvcmdparams}
+% \item[1.1] \rkeyname{morefvcmdparams}|=|\meta{command$_1$}\meta{number$_1$}\ldots\label{uoption:morefvcmdparams}
+%
+%       If you use \packagename{fancyvrb}'s \keyname{commandchars}, you must
+%       tell the \packagename{listings} package how many arguments each command
+%       takes. If a command takes no arguments, there is nothing to do.
+%
+%       The first (third, fifth, \ldots) parameter to the keys is the command
+%       and the second (fourth, sixth, \ldots) is the number of arguments
+%       that command takes. So, if you want to use |\textcolor{red}{keyword}|
+%       with the \packagename{fancyvrb}-\packagename{listings} interface, you
+%       should write |\lstset{morefvcmdparams=\textcolor 2}|.
+% \end{syntax}
+%
+% \iffancyvrb
+% \begin{lstsample}{}{}
+%    \lstset{morecomment=[l]\ }% :-)
+%    \fvset{commandchars=\\\{\}}
+%
+%    \begin{BVerbatim}
+%    First verbatim line.
+%    \fbox{Second} verbatim line.
+%    \end{BVerbatim}
+%
+%    \par\vspace{72.27pt}
+%
+%    \lstset{fancyvrb}
+%    \begin{BVerbatim}
+%    First verbatim line.
+%    \fbox{Second} verbatim line.
+%    \end{BVerbatim}
+%    \lstset{fancyvrb=false}
+% \end{lstsample}
+% The lines typeset by the \packagename{listings} package are wider since the
+% default \ikeyname{basewidth} doesn't equal the width of a single typewriter type
+% character. Moreover, note that the first space begins a comment as defined at
+% the beginning of the example.
+% \else
+% \begin{center}
+%    \packagename{fancyvrb} seems to be unavailable on your platform, thus the
+%    example couldn't be printed here.
+% \end{center}
+% \fi
+%
+%
+% \subsection{Environments}\label{rEnvironments}
+%
+% If you want to define your own pretty-printing environments, try the
+% following command. The syntax comes from \LaTeX's |\newenvironment|.
+% \begin{syntax}
+% \item[0.19] \rcmdname\lstnewenvironment\\
+%       \marg{name}\oarg{number}\oarg{opt.~default~arg.}\\
+%       |{|\meta{starting code}|}|\\
+%       |{|\meta{ending code}|}|
+% \end{syntax}
+% As a simple example we could just select a particular language.
+% \begin{lstxsample}
+%    \lstnewenvironment{pascal}
+%        {\lstset{language=pascal}}
+%        {}
+% \end{lstxsample}
+% \begin{lstsample}{}{}
+%    \begin{pascal}
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    \end{pascal}
+% \end{lstsample}
+% Doing other things is as easy, for example, using more keys and adding an
+% optional argument to adjust settings each listing:
+% \begin{verbatim}
+%\lstnewenvironment{pascalx}[1][]
+%    {\lstset{language=pascal,numbers=left,numberstyle=\tiny,float,#1}}
+%    {}\end{verbatim}
+%
+%
+% \subsection{Short Inline Listing Commands}\label{rShortInline}
+%
+% Short equivalents of |\lstinline| can also be defined, in a manner similar
+% to the short verbatim macros provided by \packagename{shortvrb}.
+%
+% \begin{syntax}
+% \item[1.4] \rcmdname\lstMakeShortInline[\oarg{options}]\meta{character}
+%
+%       defines \meta{character} to be an equivalent of
+%       |\lstinline|[\oarg{options}]\meta{character},
+%       allowing for a convenient syntax when using lots of inline listings.
+%
+% \item[1.4] \rcmdname\lstDeleteShortInline\meta{character}
+%
+%       removes a definition of \meta{character} created by |\lstMakeShortInline|,
+%       and returns \meta{character} to its previous meaning.
+% \end{syntax}
+%
+%
+% \subsection{Language definitions}\label{rLanguageDefinitions}
+%
+% You should first read section \ref{uLanguageDefinitions} for an introduction
+% to language definitions. Otherwise you're probably unprepared for the full
+% syntax of |\lstdefinelanguage|.
+% \begin{syntax}
+% \item[0.19] \rcmdname\lstdefinelanguage\syntaxnewline[\oarg{dialect}]\marg{language}\syntaxnewline[\oarg{base dialect}\marg{and base language}]\syntaxnewline\marg{key=value list}\syntaxnewline[\oarg{list of required aspects \textup(keywordcomments,texcs,etc.\textup)}]
+%
+%		defines the (given dialect of the) programming language \meta{language}.
+%       If the language definition is based on another definition, you must
+%       specify the whole \oarg{base dialect}\marg{and base language}. Note
+%       that an empty \meta{base dialect} uses the default dialect!
+%
+%       The last optional argument should specify all required aspects. This is
+%       a delicate point since the aspects are described in the developer's
+%       guide. You might use existing languages as templates. For example,
+%       ANSI C uses \aspectname{keywords}, \aspectname{comments},
+%       \aspectname{strings} and \aspectname{directives}.
+%
+%       \icmdname{\lst@definelanguage} has the same syntax and is used to
+%       define languages in the driver files.
+%
+% \begin{advise}
+% \item Where should I put my language definition?
+%       \advisespace
+%       If you need the language for one particular document, put it into
+%       the preamble of that document. Otherwise create the local file
+%       `\texttt{lstlang0.sty}' or add the definition to that file, but use
+%       `|\lst@definelanguage|' instead of `|\lstdefinelanguage|'.
+%       However, you might want to send the definition to the address in
+%       section \ref{uSoftwareLicense}. Then it will be included with the
+%       rest of the languages distributed with the package, and published under
+%       the \LaTeX\ Project Public License.
+% \end{advise}
+%
+% \item[0.18] \rcmdname\lstalias\marg{alias}\marg{language}
+%
+%       defines an alias for a programming language. Each \meta{alias} is
+%       redirected to the same dialect of \meta{language}.
+%       It's also possible to define an alias for one particular dialect only:
+%
+% \item[0.18] \rcmdname\lstalias\oarg{alias dialect}\marg{alias}\oarg{dialect}\marg{language}
+%
+%       Here all four parameters are \emph{nonoptional} and an alias with empty
+%       \meta{dialect} will select the default dialect. Note that aliases
+%       cannot be chained: The two aliases `|\lstalias{foo1}{foo2}|' and
+%       `|\lstalias{foo2}{foo3}|' will \emph{not} redirect |foo1| to |foo3|.
+% \end{syntax}
+% All remaining keys in this section are intended for building language
+% definitions. \emph{No other key should be used in such a definition!}
+%
+%
+% \paragraph{Keywords}
+% We begin with keyword building keys. Note: {\itshape If you want to enter
+% {\upshape|\|, |{|, |}|, |%|, |#|} or {\upshape|&|} as (part of) an argument
+% to the keywords below, you must do it with a preceding backslash!}
+% \begin{syntax}
+% \item[1.0,,{\dag bug}] \rkeyname{keywordsprefix}|=|\meta{prefix}
+%
+%       All identifiers starting with \meta{prefix} will be printed as first
+%       order keywords.
+%
+%       Bugs: Currently there are several limitations.
+%       (1) The prefix is always case sensitive.
+%       (2) Only one prefix can be defined at a time.
+%       (3) If used `standalone' outside a language definition, the key might
+%           work only after selecting a nonempty language (and switching back to
+%           the empty language if necessary).
+%       (4) The key does not respect the value of \keyname{classoffset} and
+%           has no optional class \meta{number} argument.
+%
+% \item[0.11] \rkeyname{keywords}|=|\oarg{number}\marg{list of keywords}
+% \item[0.11] \rkeyname{morekeywords}|=|\oarg{number}\marg{list of keywords}
+% \item[0.18] \rkeyname{deletekeywords}|=|\oarg{number}\marg{list of keywords}
+%
+%       define, add to or remove the keywords from keyword list \meta{number}.
+%       The use of \keyname{keywords} is discouraged since it deletes all
+%       previously defined keywords in the list and is thus incompatible with
+%       the \keyname{alsolanguage} key.
+%
+%       Please note the keys \ikeyname{alsoletter} and \ikeyname{alsodigit}
+%       below if you use unusual charaters in keywords.
+%
+% \item[0.19,,deprecated] \rkeyname{ndkeywords}|=|\marg{list of keywords}
+% \item[0.19,,deprecated] \rkeyname{morendkeywords}|=|\marg{list of keywords}
+% \item[0.19,,deprecated] \rkeyname{deletendkeywords}|=|\marg{list of keywords}
+%
+%       define, add to or remove the keywords from keyword list 2; note that
+%       this is equivalent to |keywords=[2]|\ldots etc.
+%       The use of \keyname{ndkeywords} is strongly discouraged.
+%
+% \item[0.19,,{addon,optional}] \rkeyname{texcs}|=|\oarg{class number}\marg{list of control sequences \textup(without backslashes\textup)}
+% \item[0.20,,{addon,optional}] \rkeyname{moretexcs}|=|\oarg{class number}\marg{list of control sequences \textup(without backslashes\textup)}
+% \item[0.21,,{addon,optional}] \rkeyname{deletetexcs}|=|\oarg{class number}\marg{list of control sequences \textup(without backslashes\textup)}
+%
+%       Ditto for control sequences in \TeX\ and \LaTeX.
+%
+% \item[0.18,,optional] \rkeyname{directives}|=|\marg{list of compiler directives}
+% \item[0.21,,optional] \rkeyname{moredirectives}|=|\marg{list of compiler directives}
+% \item[0.21,,optional] \rkeyname{deletedirectives}|=|\marg{list of compiler directives}
+%
+%       defines compiler directives in C, \Cpp, Objective-C, and POV.
+%
+% \item[0.14] \rkeyname{sensitive}|=|\meta{\alternative{true,false}}
+%
+%       makes the keywords, control sequences, and directives case sensitive
+%       and insensitive, respectively. This key affects the keywords, control
+%       sequences, and directives only when a listing is processed. In all
+%       other situations they are case sensitive, for example,
+%       |deletekeywords={save,Test}| removes `save' and `Test', but neither
+%       `SavE' nor `test'.
+%
+% \item[0.19] \rkeyname{alsoletter}|=|\marg{character sequence}
+% \item[0.19] \rkeyname{alsodigit}|=|\marg{character sequence}
+% \item[0.19] \rkeyname{alsoother}|=|\marg{character sequence}
+%
+%       All identifiers (keywords, directives, and such) consist of a letter
+%       followed by alpha-numeric characters (letters and digits).
+%       For example, if you write
+%           |keywords={one-two,\#include}|,
+%       the minus sign must become a digit and the sharp a letter since the
+%       keywords can't be detected otherwise.
+%
+%       Table \ref{rStdCharTable} show the standard configuration of the
+%       \packagename{listings} package. The three keys overwrite the default
+%       behaviour. Each character of the sequence becomes a letter, digit
+%       and other, respectively.
+%
+% \item[0.20] \rkeyname{otherkeywords}|=|\marg{keywords}
+%
+%       Defines keywords that contain other characters, or start with digits.
+%       Each given `keyword' is printed in keyword style, but without changing
+%       the `letter', `digit' and `other' status of the characters. This key
+%       is designed to define keywords like |=>|, |->|, |-->|, |--|, |::|, and
+%       so on. If one keyword is a subsequence of another (like |--| and
+%       |-->|), you must specify the shorter first.
+%
+% \item[0.20,,{renamed,optional}] \rkeyname{tag}|=|\meta{character}\meta{character}\syntaxor\rkeyname{tag}|={}|\label{uoption:tag}
+%
+%       The first order keywords are active only between the first and second
+%       character. This key is used for HTML.

+% \paragraph{Strings}
+% \begin{syntax}
+% \item[0.12] \rkeyname{string}|=|\oarg{\alternative{b,d,m,bd,s}}\marg{delimiter \textup(character\textup)}
+% \item[0.21] \rkeyname{morestring}|=|\oarg{\alternative{b,d,m,bd,s}}\marg{delimiter}
+% \item[0.21] \rkeyname{deletestring}|=|\oarg{\alternative{b,d,m,bd,s}}\marg{delimiter}
+%
+%       define, add to or delete the delimiter from the list of string
+%       delimiters. Starting and ending delimiters are the same, i.e.~in the
+%       source code the delimiters must match each other.
+%
+%       The optional argument is the type and controls the how the delimiter
+%       itself is represented in a string or character literal: it is escaped by a
+%       |b|ackslash, |d|oubled (or both is allowed via |bd|).  Alternately, the
+%       type can refer to an unusual form of delimiter: |s|tring delimiters (akin
+%       to the |s| comment type) or |m|atlab-style delimiters.  The latter is a
+%       special type for Ada and Matlab and possibly other languages where the
+%       string delimiters are also used for other purposes.  It is equivalent
+%       to |d|, except that a string does not start after a letter, a right
+%       parenthesis, a right bracket, or some other characters.
+% \end{syntax}
+%
+%
+% \paragraph{Comments}
+% \begin{syntax}
+% \item[0.13] \rkeyname{comment}|=|\oarg{type}\meta{delimiter\textup(s\textup)}
+% \item[0.21] \rkeyname{morecomment}|=|\oarg{type}\meta{delimiter\textup(s\textup)}
+% \item[0.21] \rkeyname{deletecomment}|=|\oarg{type}\meta{delimiter\textup(s\textup)}
+%
+%       Ditto for comments, but some types require more than a single
+%       delimiter. The following overview uses \keyname{morecomment} as the
+%       example, but the examples apply to \keyname{comment} and \keyname{deletecomment}
+%       as well.
+%
+% \item[0.13] \keyname{morecomment}|=[l]|\meta{delimiter}
+%
+%       The delimiter starts a comment line, which in general starts with the
+%       delimiter and ends at end of line. If the character sequence |//|
+%       should start a comment line (like in \Cpp, Comal 80 or Java),
+%       |morecomment=[l]//| is the correct declaration. For Matlab it
+%       would be |morecomment=[l]\%|---note the preceding backslash.
+%
+% \item[0.13] \keyname{morecomment}|=[s]|\marg{delimiter}\marg{delimiter}
+%
+%       Here we have two delimiters. The second ends a comment starting with
+%       the first delimiter. If you require two such comments you can use this
+%       type twice. C, Java, PL/I, Prolog and SQL all define single comments
+%       via |morecomment=[s]{/*}{*/}|, and Algol does it with
+%       |morecomment=[s]{\#}{\#}|, which means that the sharp delimits both
+%       beginning and end of a single comment.
+%
+% \item[0.13] \keyname{morecomment}|=[n]|\marg{delimiter}\marg{delimiter}
+%
+%       is similar to type |s|, but comments can be nested. Identical arguments
+%       are not allowed---think a while about it!
+%       Modula-2 and Oberon-2 use |morecomment=[n]{(*}{*)}|.
+%
+% \item[0.18] \keyname{morecomment}|=[f]|\meta{delimiter}
+% \item[0.18] \keyname{morecomment}|=[f][commentstyle]|\oarg{n=preceding columns}\meta{delimiter}
+%
+%       The delimiter starts a comment line if and only if it appears on a
+%       fixed column-number, namely if it is in column $n$ (zero based).
+%
+% \item[0.17,,optional] \rkeyname{keywordcomment}|=|\marg{keywords}
+% \item[0.21,,optional] \rkeyname{morekeywordcomment}|=|\marg{keywords}
+% \item[0.21,,optional] \rkeyname{deletekeywordcomment}|=|\marg{keywords}
+%
+%       A keyword comment begins with a keyword and ends with the same keyword.
+%       Consider |keywordcomment={comment,co}|. Then
+%       `\textbf{comment}\allowbreak\ldots\textbf{comment}' and
+%       `\textbf{co}\ldots\textbf{co}' are comments.
+%
+% \item[0.17,,optional] \rkeyname{keywordcommentsemicolon}|=|\marg{keywords}\marg{keywords}\marg{keywords}
+%
+%       The definition of a `keyword comment semicolon' requires three keyword
+%       lists, e.g.~|{end}{else,end}{comment}|. A semicolon always ends such a
+%       comment. Any keyword of the first argument begins a comment and any
+%       keyword of the second argument ends it (and a semicolon also);
+%       a comment starting with any keyword of the third argument is terminated
+%       with the next semicolon only. In the example all possible comments are
+%       `\textbf{end}\ldots\textbf{else}', `\textbf{end}\ldots\textbf{end}'
+%       (does not start a comment again) and `\textbf{comment}\ldots;' and
+%       `\textbf{end}\ldots;'.
+%       Maybe a curious definition, but Algol and Simula use such comments.
+%
+%       Note: The keywords here need not to be a subset of the defined
+%       keywords. They won't appear in keyword style if they aren't.
+%
+% \item[0.17,,optional] \rkeyname{podcomment}|=|\meta{\alternative{true,false}}
+%
+%       activates or deactivates PODs---Perl specific.
+% \end{syntax}
+%
+%
+% \subsection{Installation}\label{rInstallation}
+%
+% \paragraph{Software installation}
+% \begin{enumerate}
+% \item Following the \TeX\ directory structure (TDS), you should put the files
+%       of the \packagename{listings} package into directories as follows:
+%       \begin{center}
+%       \begin{tabular}{lcl}
+%       \texttt{listings.pdf}&$\to$&\texttt{texmf/doc/latex/listings}\\
+%       \texttt{listings.dtx}, \texttt{listings.ins},\\
+%       \texttt{listings.ind}, \texttt{lstpatch.sty},\\
+%       \texttt{lstdrvrs.dtx}&$\to$&\texttt{texmf/source/latex/listings}
+%       \end{tabular}
+%       \end{center}
+%       Note that you may not have a patch file \texttt{lstpatch.sty}.
+%       If you don't use the TDS, simply adjust the directories below.
+% \item	Create the directory \texttt{texmf/tex/latex/listings} or, if it exists
+%       already, remove all
+%       files except \texttt{lst}\meta{whatever}\texttt{0.sty} and
+%       \texttt{lstlocal.cfg} from it.
+% \item	Change the working directory to \texttt{texmf/source/latex/listings}
+%       and run \texttt{listings.ins} through \TeX.
+% \item Move the generated files to \texttt{texmf/tex/latex/listings} if this
+%       is not already done.
+%       \begin{center}
+%       \begin{tabular}{lcl}
+%       \texttt{listings.sty}, \texttt{lstmisc.sty},
+%           &&\qquad(kernel and add-ons)\\
+%       \texttt{listings.cfg},
+%           &&\qquad(configuration file)\\
+%       \texttt{lstlang}\meta{number}\texttt{.sty},
+%           &&\qquad(language drivers)\\
+%       \texttt{lstpatch.sty}&$\to$&\texttt{texmf/tex/latex/listings}
+%       \end{tabular}
+%       \end{center}
+% \item If your \TeX\ implementation uses a file name database, update it.
+% \item If you receive a patch file later on, put it where
+%       \texttt{listings.sty} is (and update the file name database).
+% \end{enumerate}
+% Note that \packagename{listings} requires at least version 1.10 of the
+% \packagename{keyval} package included in the \packagename{graphics} bundle by
+% David Carlisle.
+%
+%
+% \paragraph{Software configuration}
+% Read this only if you encounter problems with the standard configuration or
+% if you want the package to suit foreign languages, for example.
+%
+% Never modify a file from the \packagename{listings} package, in particular
+% not the configuration file. Each new installation or new version overwrites
+% it. The software license allows modification, but I can't recommend it.
+% It's better to create one or more of the files
+% \begin{center}
+% \begin{tabular}{lcl}
+% \texttt{lstmisc0.sty} & for & local add-ons
+%                               (see the developer's guide),\\
+% \texttt{lstlang0.sty} & for & local language definitions
+%                               (see \ref{rLanguageDefinitions}), and\\
+% \texttt{lstlocal.cfg} & as  & local configuration file
+% \end{tabular}
+% \end{center}
+% and put them in the same directory as the other \packagename{listings} files.
+% These three files are not touched by a new installation unless you remove them.
+% If \texttt{lstlocal.cfg} exists, it is loaded after \texttt{listings.cfg}.
+% You might want to change one of the following parameters.
+% \begin{syntax}
+% \item[,,data] \rcmdname\lstaspectfiles\quad contains~\rlap{\texttt{\lstaspectfiles}}
+% \item[,,data] \rcmdname\lstlanguagefiles\quad contains~\rlap{\texttt{\lstlanguagefiles}}
+%
+%       The package uses the specified files to find add-ons and language
+%       definitions.
+% \end{syntax}
+% Moreover, you might want to adjust
+%   \icmdname\lstlistlistingname,
+%   \icmdname\lstlistingname,
+%   \ikeyname{defaultdialect},
+%   \icmdname\lstalias, or
+%   \icmdname\lstalias
+% \ as described in earlier sections.
+%
+%
+% \section{Experimental features}\label{rExperimentalFeatures}
+%
+% This section describes the more or less unestablished parts of this package.
+% It's unlikely that they will all be removed (unless stated explicitly), but
+% they are liable to (heavy) changes and improvements. Such features have been
+% \dag-marked in the last sections. So, if you find anything \dag-marked here,
+% you should be very, very careful.
+%
+%
+% \subsection{Listings inside arguments}\label{rListingsInsideArguments}
+%
+% There are some things to consider if you want to use |\lstinline| or the
+% listing environment inside arguments. Since \TeX\ reads the argument before
+% the `\lst-macro' is executed, this package can't do anything to preserve the
+% input: spaces shrink to one space, the tabulator and the end of line are
+% converted to spaces, \TeX's comment character is not printable, and so on.
+% Hence, \emph{you} must work a bit more. You have to put a backslash in front
+% of each of the following four characters: |\{}%|. Moreover you must protect
+% spaces in the same manner if: (i) there are two or more spaces following each
+% other or (ii) the space is the first character in the line.
+% That's not enough: Each line must be terminated with a `line feed' |^^J|.
+% And you can't escape to \LaTeX\ inside such listings!
+%
+% The easiest examples are with |\lstinline| since we need no line feed.
+% \begin{verbatim}
+%\footnote{\lstinline{var i:integer;} and
+%          \lstinline!protected\ \ spaces! and
+%          \fbox{\lstinline!\\\{\}\%!}}\end{verbatim}
+% yields\lstset{language=Pascal}\footnote{\lstinline{var i:integer;} and
+%          \lstinline!protected\ \ spaces! and
+%          \fbox{\lstinline!\\\{\}\%!}}
+% if the current language is Pascal. Note that this example shows another
+% experimental feature: use of argument braces as delimiters. This is
+% described in section \ref{rTypesettingListings}.
+%
+% And now an environment example:
+% \begin{lstsample}{\lstset{language={}}}{}
+%    \fbox{%
+%    \begin{lstlisting}^^J
+%    \ !"#$\%&'()*+,-./^^J
+%    0123456789:;<=>?^^J
+%    @ABCDEFGHIJKLMNO^^J
+%    PQRSTUVWXYZ[\\]^_^^J
+%    `abcdefghijklmno^^J
+%    pqrstuvwxyz\{|\}~^^J
+%    \end{lstlisting}}
+% \end{lstsample}
+% \begin{advise}
+% \item You might wonder that this feature is still experimental. The reason:
+%       You shouldn't use listings inside arguments; it's not always safe.
+% \end{advise}
+%
+%
+% \subsection{\dag\ Export of identifiers}\label{rExportOfIdentifiers}
+%
+% It would be nice to export function or procedure names. In general that's a
+% dream so far. The problem is that programming languages use various syntaxes
+% for function and procedure declaration or definition. A general interface is
+% completely out of the scope of this package---that's the work of a compiler
+% and not of a pretty-printing tool. However, it is possible for particular
+% languages: in Pascal, for instance, each function or procedure definition and
+% variable declaration is preceded by a particular keyword.
+% Note that you must request the following keys with the \texttt{procnames} option:
+% |\usepackage[procnames]{listings}|.
+% \begin{syntax}
+% \item[0.19,{{}},{\dag optional}] \rkeyname{procnamekeys}|=|\marg{keywords}
+% \item[0.21,,\dag optional] \rkeyname{moreprocnamekeys}|=|\marg{keywords}
+% \item[0.21,,\dag optional] \rkeyname{deleteprocnamekeys}|=|\marg{keywords}
+%
+%		each specified keyword indicates a function or procedure definition.
+%		Any identifier following such a keyword appears in `procname' style.
+%		For Pascal you might use\vspace{-.5\baselineskip}
+% \begin{verbatim}
+%    procnamekeys={program,procedure,function}\end{verbatim}
+%
+% \item[0.19,keywordstyle,\dag optional] \rkeyname{procnamestyle}|=|\meta{style}
+%
+%		defines the style in which procedure and function names appear.
+%
+% \item[0.19,false,\dag optional] \rkeyname{indexprocnames}|=|\meta{\alternative{true,false}}
+%
+%		If activated, procedure and function names are also indexed.
+% \end{syntax}
+% \begin{TODO}
+% The \aspectname{procnames} aspect is unsatisfactory (and has been unchanged
+% at least since 2000). It marks and indexes the function definitions so far, but
+% it would be possible to mark also the following function calls, for example.
+% A key could control whether function names are added to a special keyword
+% class, which then appears in `procname' style. But should these names be
+% added globally? There are good reasons for both. Of course, we would also
+% need a key to reset the name list.
+% \end{TODO}
+%
+%
+% \subsection{\dag\ Hyperlink references}\label{rHyperReferences}
+%
+% This very small aspect must be requested via the \texttt{hyper} option since it
+% is experimental. One possibility for the future is to combine this aspect
+% with \aspectname{procnames}. Then it should be possible to click on a
+% function name and jump to its definition, for example.
+% \begin{syntax}
+% \item[0.21,,{\dag optional}] \rkeyname{hyperref}|=|\marg{identifiers}
+% \item[0.21,,{\dag optional}] \rkeyname{morehyperref}|=|\marg{identifiers}
+% \item[0.21,,{\dag optional}] \rkeyname{deletehyperref}|=|\marg{identifiers}
+%
+%       hyperlink the specified identifiers (via \packagename{hyperref}
+%       package). A `click' on such an identifier jumps to the previous
+%       occurrence.
+%
+% \item[0.21,\hyper@@anchor,{\dag optional}] \rkeyname{hyperanchor}|=|\meta{two-parameter macro}
+% \item[0.21,\hyperlink,{\dag optional}] \rkeyname{hyperlink}|=|\meta{two-parameter macro}
+%
+%       set a hyperlink anchor and link, respectively.
+%       The defaults are suited for the \packagename{hyperref} package.
+% \end{syntax}
+%
+%
+% \subsection{Literate programming}
+%
+% We begin with an example and hide the crucial key=value list.
+% \begin{lstsample}{\lstset{literate={:=}{{$\gets$}}1 {<=}{{$\leq$}}1 {>=}{{$\geq$}}1 {<>}{{$\neq$}}1}}{}
+%    \begin{lstlisting}
+%    var i:integer;
+%
+%    if (i<=0) i := 1;
+%    if (i>=0) i := 0;
+%    if (i<>0) i := 0;
+%    \end{lstlisting}
+% \end{lstsample}
+% Funny, isn't it? We could leave |i := 0| in our listings instead of
+% i| |$\gets$| |0, but that's not literate!  ^^A :-)
+% Now you might want to know how this has been done. Have a \emph{close}
+% look at the following key.
+% \begin{syntax}
+% \item[0.20,,\dag] \rkeyname{literate}|=|[|*|]\meta{replacement item}\ldots\meta{replacement item}
+%
+%       First note that there are no commas between the items. Each item
+%       consists of three arguments:
+%           \marg{replace}\marg{replacement text}\marg{length}.
+%       \meta{replace} is the original character sequence.
+%       Instead of printing these characters, we use \meta{replacement text},
+%       which takes the width of \meta{length} characters in the output.
+%
+%       Each `printing unit' in \meta{replacement text} \emph{must} be in braces
+%       unless it's a single character. For example, you must put braces
+%       around |$\leq$|.
+%       If you want to replace |<-1->| by |$\leftarrow1\rightarrow$|, the
+%       replacement item would be |{<-1->}{{$\leftarrow$}1{$\rightarrow$}}3|.
+%       Note the braces around the arrows.
+%
+%       If one \meta{replace} is a subsequence of another \meta{replace}, you
+%       must define the shorter sequence first. For example, |{-}| must be defined
+%       before |{--}| and this before |{-->}|.
+%
+%       The optional star indicates that literate replacements should not be
+%       made in strings, comments, and other delimited text.
+% \end{syntax}
+% In the example above, I've used
+% \begin{verbatim}
+%  literate={:=}{{$\gets$}}1 {<=}{{$\leq$}}1 {>=}{{$\geq$}}1 {<>}{{$\neq$}}1\end{verbatim}
+% \begin{TODO}
+% Of course, it's good to have keys for adding and removing single
+% \meta{replacement item}s. Maybe the key(s) should work in the same fashion
+% as the string and comment definitions, i.e.~one item per key=value.
+% This way it would be easier to provide better auto-detection in case of a
+% subsequence.
+% \end{TODO}
+%
+%
+% \subsection{\textsf{LGrind} definitions}\label{rLGrindDefinitions}
+%
+% Yes, it's a nasty idea to steal language definitions from other programs.
+% Nevertheless, it's possible for the \packagename{LGrind} definition
+% file---at least partially. Please note that this file must be found by
+% \TeX.
+% \begin{syntax}
+% \item[0.21,,{optional}] \rkeyname{lgrindef}|=|\meta{language}
+%
+%       scans the \texttt{lgrindef} language definition file for
+%       \meta{language} and activates it if present. Note that not all
+%       \packagename{LGrind} capabilities have a \packagename{listings}
+%       analogue.
+%
+%       Note that `Linda' language doesn't work properly since it defines
+%       compiler directives with preceding `|#|' as keywords.
+%
+% \item[0.21,lgrindef.,{data,optional}] \rcmdname\lstlgrindeffile
+%
+%       contains the (path and) name of the definition file.
+% \end{syntax}
+%
+%
+% \subsection{\dag\ Automatic formatting}
+%
+% \lstloadaspects{formats}^^A
+% The automatic source code formatting is far away from being good. First of
+% all, there are no general rules on how source code should be formatted. So
+% `format definitions' must be flexible. This flexibility requires a complex
+% interface, a powerful `format definition' parser, and lots of code lines
+% behind the scenes. Currently, format definitions aren't flexible enough
+% (possibly not the definitions but the results). A single `format item' has
+% the form 
+% \begin{itemize}\item[]
+%     \meta{input chars}|=|\oarg{exceptional chars}\meta{pre}\oarg{\texttt{\string\string}}\meta{post}
+% \end{itemize}
+% Whenever \meta{input chars} aren't followed by one of the \meta{exceptional
+% chars}, formatting is done according to the rest of the value. If |\string|
+% isn't specified, the input characters aren't printed (except it's an
+% identifier or keyword). Otherwise \meta{pre} is `executed' before printing
+% the original character string and \meta{post} afterwards. These two are
+% `subsets' of
+% \begin{itemize}
+% \item |\newline| ---ensuring a new line;
+% \item |\space| ---ensuring a whitespace;
+% \item |\indent| ---increasing indention;
+% \item |\noindent| ---descreasing indention.
+% \end{itemize}
+% Now we can give an example.\lstaspectindex{\lstdefineformat}{}\lstaspectindex{format}{}
+% \begin{lstxsample}
+%    \lstdefineformat{C}{%
+%        \{=\newline\string\newline\indent,%
+%        \}=\newline\noindent\string\newline,%
+%        ;=[\ ]\string\space}
+% \end{lstxsample}
+% \begin{lstsample}{\lstset{language={}}}{}
+%    \begin{lstlisting}[format=C]
+%    for (int i=0;i<10; i++){/* wait */};
+%    \end{lstlisting}
+% \end{lstsample}
+% Not good. But there is a (too?) simple work-around:
+% \begin{lstxsample}
+%    \lstdefineformat{C}{%
+%        \{=\newline\string\newline\indent,%
+%        \}=[;]\newline\noindent\string\newline,%
+%        \};=\newline\noindent\string\newline,%
+%        ;=[\ ]\string\space}
+% \end{lstxsample}
+% \begin{lstsample}{\lstset{language={}}}{}
+%    \begin{lstlisting}[format=C]
+%    for (int i=0;i<10; i++){/* wait */};
+%    \end{lstlisting}
+% \end{lstsample}
+% Sometimes the problem is just to find a suitable format definition.
+% Further formatting is complicated.
+% Here are only three examples with increasing level of difficulty.
+% \begin{enumerate}
+% \item Insert horizontal space to separate function/procedure name and
+%       following parenthesis or to separate arguments of a function,
+%       e.g.~add the space after a comma (if inside function call).
+% \item Smart breaking of long lines. Consider long `and/or' expressions.
+%       Formatting should follow the logical structure!
+% \item Context sensitive formatting rules. It can be annoying if empty
+%       or small blocks take three or more lines in the output---think of
+%       scrolling down all the time. So it would be nice if the block
+%       formatting was context sensitive.
+% \end{enumerate}
+% Note that this is a very first and clumsy attempt to provide automatic
+% formatting---clumsy since the problem isn't trivial. Any ideas are welcome.
+% Implementations also. Eventually you should know that you must request format
+% definitions at package loading, e.g.~via |\usepackage[formats]{listings}|.
+%
+% \subsection{Arbitrary linerange markers}\label{rArbitraryLinerangeMarkers}
+%
+% Instead of using \keyname{linerange} with line numbers, one can use text
+% markers. Each such marker consists of a \meta{prefix}, a \meta{text}, and a
+% \meta{suffix}. You once (or more) define prefixes and suffixes and then use
+% the marker text instead of the line numbers.
+% \begin{lstxsample}
+%    \lstset{rangeprefix=\{\ ,% curly left brace plus space
+%            rangesuffix=\ \}}% space plus curly right brace
+% \end{lstxsample}
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}%
+%          [linerange=loop\ 2-end]
+%    { loop 1 }
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    { end }
+%    { loop 2 }
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    { end }
+%    \end{lstlisting}
+% \end{lstsample}
+% Note that \TeX's special characters like the curly braces, the space, the
+% percent sign, and such must be escaped with a backslash.
+% \begin{syntax}
+% \item[1.2] \rkeyname{rangebeginprefix}|=|\meta{prefix}
+% \item[1.2] \rkeyname{rangebeginsuffix}|=|\meta{suffix}
+% \item[1.2] \rkeyname{rangeendprefix}|=|\meta{prefix}
+% \item[1.2] \rkeyname{rangeendsuffix}|=|\meta{suffix}
+%
+%       define individual prefixes and suffixes for the begin- and end-marker.
+%
+% \item[1.2] \rkeyname{rangeprefix}|=|\meta{prefix}
+% \item[1.2] \rkeyname{rangesuffix}|=|\meta{suffix}
+%
+%       define identical prefixes and suffixes for the begin- and end-marker.
+%
+% \item[1.2,true] \rkeyname{includerangemarker}|=|\meta{\alternative{true,false}}
+%
+%       shows or hides the markers in the output.
+% \end{syntax}
+% \begin{lstsample}{\lstset{rangeprefix=\{\ ,rangesuffix=\ \}}}{}
+%    \begin{lstlisting}%
+%          [linerange=loop\ 1-end,
+%           includerangemarker=false,
+%           frame=single]
+%    { loop 1 }
+%    for i:=maxint to 0 do
+%    begin
+%        { do nothing }
+%    end;
+%    { end }
+%    \end{lstlisting}
+% \end{lstsample}
+%
+%
+% \subsection{Multicolumn Listings}\label{rMulticolumnListings}
+%
+% When the \packagename{multicol} package is loaded, it can be used to typeset
+% multi-column listings.  These are specified with the |multicols| key.  For
+% example:
+% \begin{lstsample}{}{}
+%    \begin{lstlisting}[multicols=2]
+%    if (i < 0)
+%      i = 0
+%      j = 1
+%    end if
+%    if (j < 0)
+%      j = 0
+%    end if
+%    \end{lstlisting}
+% \end{lstsample}
+%
+% The multicolumn option is known to fail with some keys.
+%
+% \begin{advise}
+% \item Which keys?
+%       \advisespace
+%       Unfortunately, I don't know.  Carsten left the code for this option
+%       in the version 1.3b patch file with only that cryptic note for
+%       documentation.  Bug reports would be welcome, though I don't promise
+%       that they're fixable.  ---Brooks

+% \section{Forthcoming ?}
+%
+% This section is rather rudimentary. It just lists some things I don't want
+% to forget.
+%
+% First of all, I'd like to support even more languages, for example Maple,
+% PostScript, and so on. Fortunately my lifetime is limited, so other
+% people may do that work. Please (e-)mail me your language definitions.
+%
+% Then, there are several ideas for the future. Some have already been stated
+% as `to do's; some came from other people and are stated below; some more are
+% far from being implemented,
+%   e.g.~\keyname{linerange}|=|\oarg{inter}\marg{line range list}
+% which prints all lines in the range and executes \meta{inter} when omitting
+% some code lines. The main problem here are frames and background colours;
+% what should happen to them? In fact, the problem is how this can be coded.
+% Another idea is to change the background colour (or the basic style) for
+% particular code blocks. This, too, is not easy.
+%
+%^^A Auto-detect whether surplus space (from spaces and tabs) isn't needed to fix
+%^^A alignment of wide character combinations like |==| or |<>|.
+%^^A
+%^^A Make package compatible to calc package.
+%^^A
+%^^A Rewrite \lst@LAS, \lst@DefDriver, \lst@Require to distinguish loading
+%^^A of languages (which don't need base languages at once) and aspects
+%^^A (which need required aspects to be loaded).
+%
+% \lsthelper{Vincent~Poirriez}{1999/11/18}{code examples inside caml comments}:
+% Inside caml comments, |[| and |]| should print the code in
+% between in basicstyle (or another newly introduced style). Nesting of these
+% `code example delimiters' is allowed, e.g.~|(* [[x;y]] *)|.
+%
+% \lsthelper{Claus~Atzenbeck}{1999/12/03}{`extendedchars=false' doesn't issue

+% \section{Troubleshooting}\label{uTroubleshooting}
+%
+% If you're faced with a problem with the \packagename{listings} package, there are
+% some steps you should undergo before you make a bug report. First you should
+% consult the reference guide to see whether the problem is already known. If not,
+% create a \emph{minimal} file which reproduces the problem. Follow these
+% instructions:
+% \begin{enumerate}
+% \item Start from the minimal file in section \ref{uAMinimalFile}.
+% \item Add the \LaTeX\ code which causes the problem, but keep it short.
+%       In particular, keep the number of additional packages small.
+% \item Remove some code from the file (and the according packages) until the
+%       problem disappears. Then you've found a crucial piece.
+% \item Add this piece of code again and start over with step 3 until all code
+%       and all packages are substantial.
+% \item You now have a minimal file. Send a bug report to the address on the
+%       first page of this documentation and include the minimal file together
+%       with the created \texttt{.log}-file. If you use a very special package
+%       (i.e.~one not on CTAN), also include the package if its software license
+%       allows it.
+% \end{enumerate}

+% \section{How tos}\label{uHowTos}
+%
+%
+% \subsubsection*{How to reference line numbers}
+% Perhaps you want to put |\label{|\meta{whatever}|}| into a \LaTeX\ escape which is
+% inside a comment whose delimiters aren't printed?  If you did that, the compiler
+% won't see the \LaTeX\ code since it would be inside a comment, and the
+% \packagename{listings} package wouldn't print anything since the delimiters would
+% be dropped and |\label| doesn't produce any printable output, but you could still
+% reference the line number. Well, your wish is granted.
+%
+% In Pascal, for example, you could make the package recognize the `special'
+% comment delimiters |(*@| and |@*)| as begin-escape and end-escape sequences.
+% Then you can use this special comment for |\label|s and other things.
+% \begin{lstsample}{\lstset{numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{}
+%    \lstset{escapeinside={(*@}{@*)}}
+%
+%    \begin{lstlisting}
+%    for i:=maxint to 0 do
+%    begin
+%        { comment }(*@\label{comment}@*)
+%    end;
+%    \end{lstlisting}
+%    Line \ref{comment} shows a comment.
+% \end{lstsample}
+% \begin{advise}
+% \item Can I use `|(*@|' and `|*)|' instead?
+%       \advisespace
+%       Yes.
+% \item Can I use `|(*|' and `|*)|' instead?
+%       \advisespace
+%       Sure. If you want this.
+% \item Can I use `|{@|' and `|@}|' instead?
+%       \advisespace
+%       No, never! The second delimiter is not allowed. The character `|@|' is
+%       defined to check whether the escape is over. But reading the lonely
+%       `end-argument' brace, \TeX\ encounters the error `\texttt{Argument of @
+%       has an extra \char125}'. Sorry.
+% \item Can I use `|{|' and `|}|' instead?
+%       \advisespace
+%       No. Again the second delimiter is not allowed. Here now \TeX\ would
+%       give you a `\texttt{Runaway argument}' error. Since `|}|' is defined to
+%       check whether the escape is over, it won't work as `end-argument' brace.
+% \item And how can I use a comment line?
+%       \advisespace
+%       For example, write `|escapeinside={//*}{\^^M}|'. Here |\^^M| represents
+%       the end of line character.
+% \end{advise}
+%
+%
+% \subsubsection*{How to gobble characters}
+% To make your \LaTeX\ code more readable, you might want to indent your
+% \texttt{lstlisting} listings. This indention should not show up in the
+% pretty-printed listings, however, so it must be removed. If you indent each code
+% line by three characters, you can remove them via |gobble=3|:
+% \begin{lstsample}{}{\lstset{showspaces}}
+%    \begin{lstlisting}[gobble=3]
+%    1  for i:=maxint to 0 do
+%     2 begin
+%      3    { do nothing }
+%    123end;
+%
+%       Write('Case insensitive ');
+%       WritE('Pascal keywords.');
+%    \end{lstlisting}
+% \end{lstsample}
+% Note that empty lines and the beginning and the end of the environment
+% need not respect the indention. However, never indent the end by more than
+% `\ikeyname{gobble}' characters. Moreover note that tabulators expand to
+% |tabsize| spaces before we gobble.
+% \begin{advise}
+% \item Could I use `\ikeyname{gobble}' together with `|\lstinputlisting|'?
+%       \advisespace
+%       Yes, but it has no effect.
+%
+% \item Note that `\ikeyname{gobble}' can also be set via `|\lstset|'.
+% \end{advise}
+%
+%
+% \subsubsection*{How to include graphics}
+% \lsthelper{Herbert~Weinhandl}{1999/09/06}{listings + eps} found a very easy
+% way to include graphics in listings. Thanks for contributing this idea---an
+% idea I would never have had.
+%
+% Some programming languages allow the dollar sign to be part of an identifier.
+% But except for intermediate function names or library functions, this
+% character is most often unused. The \packagename{listings} package defines
+% the \ikeyname{mathescape} key, which lets `|$|' escape to \TeX's math mode.
+% This makes the dollar character an excellent candidate for our purpose here:
+% use a package which can include a graphic, set \ikeyname{mathescape} true,
+% and include the graphic between two dollar signs, which are inside a comment.
+%
+% The following example is originally from a header file I got from Herbert.
+% For the presentation here I use the \texttt{lstlisting} environment and an
+% excerpt from the header file. The |\includegraphics| command is from
+% David Carlisle's \packagename{graphics} bundle.
+% \begin{verbatim}
+%   \begin{lstlisting}[mathescape=true]
+%   /*
+%    $ \includegraphics[height=1cm]{defs-p1.eps} $
+%    */
+%   typedef struct {
+%     Atom_T          *V_ptr;   /* pointer to Vacancy in grid    */
+%     Atom_T          *x_ptr;   /* pointer to (A|B) Atom in grid */
+%   } ABV_Pair_T;
+%   \end{lstlisting}\end{verbatim}
+% The result looks pretty good. Unfortunately you can't see it, because the
+% graphic wasn't available when the manual was typeset.
+%
+%
+% \subsubsection*{How to get closed frames on each page}
+% The package supports closed frames only for listings which don't cross pages.
+% If a listing is split on two pages, there is neither a bottom rule at the
+% bottom of a page, nor a top rule on the following page. If you insist on
+% these rules, you might want to use \texttt{framed.sty} by Donald Arseneau.
+% Then you could write
+% \begin{verbatim}
+%    \begin{framed}
+%    \begin{lstlisting}
+%      or \lstinputlisting{...}
+%    \end{lstlisting}
+%    \end{framed}\end{verbatim}
+% The package also provides a \texttt{shaded} environment. If you use it, you
+% shouldn't forget to define \texttt{shadecolor} with the \packagename{color}
+% package.
+%
+%
+% \subsubsection*{How to print national characters with $\Lambda$ and \packagename{listings}}\label{uNationalCharacters}
+%
+% Apart from typing in national characters directly, you can use the `escape'
+% feature described in section \ref{rEscapingToLaTeX}. 
+% The keys \ikeyname{escapechar}, \ikeyname{escapeinside}, and \ikeyname{texcl}
+% allow partial usage of \LaTeX\ code.
+%
+% Now, if you use $\Lambda$ (Lambda, the \LaTeX\ variant for Omega) and want,
+% for example, Arabic comment lines, you need not write |\begin{arab}|
+% \ldots\ |\end{arab}| each escaped comment line. This can be automated:
+% \begin{verbatim}
+%    \lstset{escapebegin=\begin{arab},escapeend=\end{arab}}
+%
+%    \begin{lstlisting}[texcl]
+%    // Replace text by Arabic comment.
+%    for (int i=0; i<1; i++) { };
+%    \end{lstlisting}\end{verbatim}
+% If your programming language doesn't have comment lines, you'll have to use
+% \ikeyname{escapechar} or \ikeyname{escapeinside}:
+% \begin{verbatim}
+%    \lstset{escapebegin=\begin{greek},escapeend=\end{greek}}
+%
+%    \begin{lstlisting}[escapeinside=`']
+%    /* `Replace text by Greek comment.' */
+%    for (int i=0; i<1; i++) { };
+%    \end{lstlisting}\end{verbatim}
+% Note that the delimiters |`| and |'| are essential here. The example doesn't
+% work without them. There is a more clever way if the comment delimiters of
+% the programming language are single characters, like the braces in Pascal:
+% \begin{verbatim}
+%    \lstset{escapebegin=\textbraceleft\begin{arab},
+%            escapeend=\end{arab}\textbraceright}
+%
+%    \begin{lstlisting}[escapeinside=\{\}]
+%    for i:=maxint to 0 do
+%    begin
+%        { Replace text by Arabic comment. }
+%    end;
+%    \end{lstlisting}\end{verbatim}
+% Please note that the `interface' to $\Lambda$ is completely untested.
+% Reports are welcome!
+%
+%
+% \subsubsection*{How to get bold typewriter type keywords}
+% Use the \href{http://www.ctan.org/tex-archive/fonts/luximono}{\packagename{LuxiMono}} package.
+% 
+% \iffalse
+% Many people asked for bold typewriter fonts since they aren't included in
+% the \LaTeX\ standard distribution. Here now one answer on how to use them
+% in spite of that.
+% \begin{advise}
+% \item Please note that I personally don't regard the following as a good
+%       solution. Such a bold typewriter type is too heavy. It would be better
+%       to use a light version of \texttt{cmtt} as basic font and \texttt{cmtt}
+%       or a \emph{slightly} heavier type for keywords.
+%
+% \item Why don't you tell us how to use the better solution?
+%       \advisespace
+%       A light version of \texttt{cmtt} doesn't exist. If it's once available,
+%       you can do a similar job as described below.
+% \end{advise}
+% First of all, you'll need Metafont source files for bold typewriter, e.g.~
+% \texttt{cmbtt8.mf}, \texttt{cmbtt9.mf} and \texttt{cmbtt10.mf} from
+% \href{ftp://ftp.dante.de/tex-archive/fonts/cm/mf-extra/bold}
+%      {CTAN/fonts/cm/mf-extra/bold}.
+% Secondly you have to create \texttt{.tfm}-files, i.e.~run the Metafont
+% program on these sources. This is possibly done automatically when you use
+% the fonts in a document. Finally you must tell \LaTeX\ that you've installed
+% bold typewriter fonts. Just use
+% \begin{verbatim}
+%    \DeclareFontShape{OT1}{cmtt}{bx}{n}
+%         {<5><6><7><8>cmbtt8%
+%          <9>cmbtt9%
+%          <10><10.95>cmbtt10%
+%          <12><14.4><17.28><20.74><24.88>cmbtt10%
+%          }{}\end{verbatim}
+% in the preamble of your document. If you use these fonts often, you might
+% want to make a local copy of \texttt{ot1cmtt.fd} and replace the declaration
+% there. But note that you're not allowed to distributed the modified file
+% under its original name!
+% \fi
+%
+%
+% \subsubsection*{How to work with plain text}
+% If you want to use \packagename{listings} to set plain text (perhaps with
+% line numbers, or like |verbatim| but with line wrapping, or so forth, use
+% the empty language: |\lstset{language=}|.
+%
+%
+% \subsubsection*{How to get the developer's guide}
+% In the \emph{source directory} of the listings package, i.e.~where
+% the \texttt{.dtx} files are, create the file \texttt{ltxdoc.cfg} with the
+% following contents.
+% \begin{verbatim}
+%    \AtBeginDocument{\AlsoImplementation}\end{verbatim}
+% Then run \texttt{listings.dtx} through \LaTeX\ twice, run Makeindex (with
+% the |-s gind.ist| option), and then run \LaTeX\ one last time on
+% \texttt{listings.dtx}. This creates the whole documentation including User's
+% guide, Reference guide, Developer's guide, and Implementation.

+% \StopEventually{\setcounter{IndexColumns}{2}\PrintIndex}
+%
+%
+% \part{Developer's guide}
+%
+% First I must apologize for this developer's guide since some parts are not
+% explained as well as possible. But note that you are in a pretty good shape:
+% this developer's guide exists! ^^A :-)
+% You might want to peek into section \ref{dPackageExtensions} before reading
+% section \ref{dBasicConcepts}.
+%
+%
+% \section{Basic concepts}\label{dBasicConcepts}
+%
+% The functionality of the \packagename{listings} package appears to be
+% divided into two parts: on the one hand commands which actually typeset
+% listings and on the other via |\lstset| adjustable parameters. Both could
+% be implemented in terms of \lst-aspects, which are simply collections of
+% public keys and commands and internal hooks and definitions. The package
+% defines a couple of aspects, in particular the kernel, the main engine.
+% Other aspects drive this engine, and language and style definitions tell
+% the aspects how to drive. The relations between car, driver and assistant
+% driver are exactly reproduced---and I'll be your driving instructor.
+%
+%
+% \subsection{Package loading}\label{dPackageLoading}
+%
+% Each option in |\usepackage[|\meta{options}|]{listings}| loads an aspect or
+% \emph{prevents} the package from loading it if the aspect name is
+% \emph{preceded by an exclamation mark}. This mechanism was designed to clear
+% up the dependencies of different package parts and to debug the package. For
+% this reason there is another option:
+% \begin{syntax}
+% \item[0.21,,option] \texttt{noaspects}\leavevmode
+%
+%       deletes the list of aspects to load. Note that, for example, the
+%       option lists |0.21,!labels,noaspects| and |noaspects| are essentially
+%       the same: the kernel is loaded and no other aspect.
+% \end{syntax}
+% This is especially useful for aspect-testing since we can load exactly the
+% required parts. Note, however, that an aspect is loaded later if a predefined
+% programming language requests it. One can load aspects also by hand:
+% \begin{syntax}
+% \item[0.20] |\lstloadaspects|\marg{comma separated list of aspect names}
+%
+%       loads the specified aspects if they are not already loaded.
+% \end{syntax}
+% Here now is a list of all aspects and related keys and commands---in the hope
+% that this list is complete.

+%
+% \subsection{How to define \lst-aspects}\label{dHowToDefineLstAspects}
+%
+% There are at least three ways to add new functionality: (a) you write an
+% aspect of general interest, send it to me, and I'll just paste it into the
+% implementation; (b) you write a `local' aspect not of general interest; or
+% (c) you have an idea for an aspect and make me writing it. (a) and (b) are
+% good choices.^^A :-)
+%
+% An aspect definition starts with |\lst@BeginAspect| plus arguments and ends
+% with the next |\lst@EndAspect|. In particular, aspect definitions can't be
+% nested.
+% \begin{syntax}
+% \item[0.20] |\lst@BeginAspect|[\oarg{list of required aspects}]\marg{aspect name}
+% \item[0.20] |\lst@EndAspect|
+% \end{syntax}
+% The optional list is a comma separated list of required aspect names.
+% The complete aspect is not defined in each of the following cases:
+% \begin{enumerate}
+% \item \meta{aspect name} is empty.
+% \item The aspect is already defined.
+% \item A required aspect is neither defined nor loadable via
+%       |\lstloadaspects|.
+% \end{enumerate}
+% Consequently you can't define a part of an aspect and later on another part.
+% But it is possible to define aspect $A_1$ and later aspect $A_2$ which
+% requires $A_1$.
+% \begin{advise}
+% \item Put local add-ons into `\texttt{lstmisc0.sty}'---this file is searched
+%       first by default. If you want to make add-ons for one particular
+%       document just replace the surrounding `|\lst@BeginAspect|' and
+%       `|\lst@EndAspect|' by `|\makeatletter|' and `|\makeatother|' and use
+%       the definitions in the preamble of your document. However, you have to
+%       load required aspects on your own.
+% \end{advise}
+% You can put any \TeX\ material in between the two commands, but note that
+% definitions must be |\global| if you need them later---\LaTeX's |\newcommand|
+% makes local definitions and can't be preceded by |\global|. So use the
+% following commands, |\gdef|, and commands described in later sections.
+% \begin{syntax}
+% \item[0.20] |\lst@UserCommand|\meta{macro}\meta{parameter text}\marg{replacement text}
+%
+%       The macro is (mainly) equivalent to |\gdef|. The purpose is to
+%       distinguish user commands and internal global definitions.
+%
+% \item[0.19] |\lst@Key|\marg{key name}\marg{init value}[\oarg{default value}]\marg{definition}
+% \item[0.19] |\lst@Key|\marg{key name}|\relax|[\oarg{default value}]\marg{definition}
+%
+%       defines a key using the \packagename{keyval} package from David
+%       Carlisle. \meta{definition} is the replacement text of a macro with
+%       one parameter. The argument is either the value from `key=value' or
+%       \meta{default value} if no `=value' is given. The helper macros
+%       |\lstKV@...| below might simplify \meta{definition}.
+%
+%       The key is not initialized if the second argument is |\relax|.
+%       Otherwise \meta{init value} is the initial value given to the key.
+%       Note that we locally switch to |\globalsdefs=1| to ensure that
+%       initialization is not effected by grouping.
+%
+% \item[0.19] |\lst@AddToHook|\marg{name of hook}\marg{\TeX\ material}
+%
+%       adds \TeX\ material at predefined points. Section \ref{dHooks} lists
+%       all hooks and where they are defined respectively executed.
+%       |\lst@AddToHook{A}{\csa}| before |\lst@AddToHook{A}{\csb}|
+%       \emph{does not} guarantee that |\csa| is executed before |\csb|.
+%
+% \item[0.20] |\lst@AddToHookExe|\marg{name of hook}\marg{\TeX\ material}
+%
+%       also executes \meta{\TeX\ material} for initialization. You might use
+%       local variables---local in the sense of \TeX\ and/or usual programming
+%       languages---but when the code is executed for initialization all
+%       assignments are global: we set |\globaldefs| locally to one.
+%
+% \item[0.20] |\lst@UseHook|\marg{name of hook}
+%
+%       executes the hook.
+% \end{syntax}
+% \begin{advise}
+% \item Let's look at two examples. The first extends the package by adding
+%       some hook-material. If you want status messages, you might write
+% \begin{verbatim}
+%    \lst@AddToHook{Init}{\message{\MessageBreak Processing listing ...}}
+%    \lst@AddToHook{DeInit}{\message{complete.\MessageBreak}}\end{verbatim}
+%       The second example introduces two keys to let the user control the
+%       messages. The macro |\lst@AddTo| is described in section
+%       \ref{dGeneralPurposeMacros}.
+% \begin{verbatim}
+%   \lst@BeginAspect{message}
+%   \lst@Key{message}{Annoying message.}{\gdef\lst@message{#1}}
+%   \lst@Key{moremessage}\relax{\lst@AddTo\lst@message{\MessageBreak#1}}
+%   \lst@AddToHook{Init}{\typeout{\MessageBreak\lst@message}}
+%   \lst@EndAspect\end{verbatim}
+%       However, there are certainly aspects which are more useful.
+% \end{advise}
+% The following macros can be used in the \meta{definition} argument of the
+% |\lst@Key| command to evaluate the argument. The additional prefix |KV|
+% refers to the \packagename{keyval} package.
+% \begin{syntax}
+% \item[0.19] |\lstKV@SetIf|\marg{value}\meta{if macro}
+%
+%       \meta{if macro} becomes |\iftrue| if the first character of
+%       \meta{value} equals |t| or |T|. Otherwise it becomes |\iffalse|.
+%       Usually you will use |#1| as \meta{value}.
+%
+% \item[1.0] \cs{lstKV@SwitchCases}\marg{value}\\
+%   |{|\meta{string 1}|&|\meta{execute 1}|\\|\\
+%   | |\meta{string 2}|&|\meta{execute 2}|\\|\\
+%   \hbox to 3em{\hfill\vdots}\\
+%   | |\meta{string $n$}|&|\meta{execute $n$}|}|\marg{else}
+%
+%       Either execute \meta{else} or the \meta{value} matching part.
+%
+% \item[0.20] |\lstKV@TwoArg|\marg{value}\marg{subdefinition}
+% \item[0.20] |\lstKV@ThreeArg|\marg{value}\marg{subdefinition}
+% \item[0.20] |\lstKV@FourArg|\marg{value}\marg{subdefinition}
+%
+%       \meta{subdefinition} is the replacement text of a macro with two,
+%       three, and four parameters. We call this macro with the arguments given
+%       by \meta{value}. Empty arguments are added if necessary.
+%
+% \item[0.19] |\lstKV@OptArg|\oarg{default arg.}\marg{value}\marg{subdefinition}
+%
+%       |[|\meta{default arg.}|]| is \emph{not} optional. \meta{subdefinition}
+%       is the replacement text of a macro with parameter text |[##1]##2|.
+%       Note that the macro parameter character |#| is doubled since used
+%       within another macro. \meta{subdefinition} accesses these arguments
+%       via |##1| and |##2|.
+%
+%       \meta{value} is usually the argument |#1| passed by the
+%       \packagename{keyval} package. If \meta{value} has no optional argument,
+%       \meta{default arg.} is inserted to provide the arguments to
+%       \meta{subdefinition}.
+%
+% \item[0.21] |\lstKV@XOptArg|\oarg{default arg.}\marg{value}\meta{submacro}
+%
+%       Same as |\lstKV@OptArg| but the third argument \meta{submacro} is
+%       already a definition and not replacement text.
+%
+% \item[0.20] |\lstKV@CSTwoArg|\marg{value}\marg{subdefinition}
+%
+%       \meta{value} is a \texttt comma \texttt separated list of one or two
+%       arguments. These are given to the subdefinition which is the
+%       replacement text of a macro with two parameters. An empty second
+%       argument is added if necessary.
+% \end{syntax}
+% \begin{advise}
+% \item One more example. The key `\keyname{sensitive}' belongs to the aspect
+%       \aspectname{keywords}. Therefore it is defined in between
+%       `|\lst@BeginAspect{keywords}|' and `|\lst@EndAspect|', which is not shown
+%       here.
+% \begin{verbatim}
+%   \lst@Key{sensitive}\relax[t]{\lstKV@SetIf{#1}\lst@ifsensitive}
+%   \lst@AddToHookExe{SetLanguage}{\let\lst@ifsensitive\iftrue}\end{verbatim}
+%       The last line is equivalent to
+% \begin{verbatim}
+%   \lst@AddToHook{SetLanguage}{\let\lst@ifsensitive\iftrue}
+%   \global\let\lst@ifsensitive\iftrue\end{verbatim}
+%       We initialize the variable globally since the user might request an
+%       aspect in a group. Afterwards the variable is used locally---there is
+%       no |\global| in \meta{\TeX\ material}. Note that we could define and
+%       init the key as follows:
+% \begin{verbatim}
+%   \lst@Key{sensitive}t[t]{\lstKV@SetIf{#1}\lst@ifsensitive}
+%   \lst@AddToHook{SetLanguage}{\let\lst@ifsensitive\iftrue}\end{verbatim}

+% \subsection{Internal modes}\label{dInternalModes}
+%
+% You probably know \TeX's conditional commands |\ifhmode|, |\ifvmode|,
+% |\ifmmode|, and |\ifinner|. They tell you whether \TeX\ is in (restricted)
+% horizontal or (internal) vertical or in (nondisplay) mathematical mode. For
+% example, true |\ifhmode| and true |\ifinner| indicate restricted horizontal
+% mode, which means that you are in a |\hbox|. The typical user doesn't care
+% about such modes; \TeX/\LaTeX\ manages all this. But since you're reading the
+% developer's guide, we discuss the analogue for the \packagename{listings}
+% package now. It uses modes to distinguish comments from strings, `comment
+% lines' from `single comments', and so on.
+%
+% The package is in `no mode' before reading the source code. In the phase of
+% initialization it goes to `processing mode'. Afterwards the mode depends on
+% the actual source code. For example, consider the line
+% \begin{verbatim}
+%    "string" // comment\end{verbatim}
+% and assume \texttt{language=C++}. Reading the string delimiter, the package
+% enters `string mode' and processes the string. The matching closing delimiter
+% leaves the mode, i.e.\ switches back to the general `processing mode'. Coming
+% to the two slashes, the package detects a comment line; it therefore enters
+% `comment line mode' and outputs the slashes. Usually this mode lasts to the
+% end of line.
+%
+% But with \texttt{textcl=true} the \aspectname{escape} aspect immediately
+% leaves `comment line mode', interrupts the current mode sequence, and enters
+% `\TeX\ comment line mode'. At the end of line we reenter the previous mode
+% sequence `no mode' $\to$ 'processing mode'. This escape to \LaTeX\ works
+% since `no mode' implies that \TeX's characters and catcodes are present,
+% whereas `processing mode' means that \packagename{listings}' characters and
+% catcodes are active.
+%

+% \end{table}
+% Table \ref{dDefinedInternalModes} lists all static modes and which aspects
+% they belong to. Most features use dynamically created mode numbers, for
+% example all strings and comments. Each aspect may define its own mode(s)
+% simply by allocating it/\allowbreak them inside the aspect definition.
+% \begin{syntax}
+% \item[0.19] |\lst@NewMode|\meta{mode \textup(control sequence\textup)}
+%
+%       defines a new static mode, which is a nonnegative integer assigned to
+%       \meta{mode}. \meta{mode} should have the prefix \texttt{lst@} and
+%       suffix \texttt{mode}.
+%
+% \item[0.21] |\lst@UseDynamicMode|\marg{token\textup(s\textup)}
+%
+%       inserts a dynamic mode number as argument to the token(s).
+%
+%       This macro cannot be used to get a mode number when an aspect is
+%       loaded or defined. It can only be used every listing in the process
+%       of initialization, e.g.~to define comments when the character table
+%       is selected.
+%
+% \item[0.19,,changed] |\lst@EnterMode|\meta{mode}\marg{start tokens}
+%
+%       opens a group level, enters the mode, and executes \meta{start tokens}.
+%
+%       Use |\lst@modetrue| in \meta{start tokens} to prohibit future mode
+%       changes---except leaving the mode, of course. You must test yourself
+%       whether you're allowed to enter, see below.
+%
+% \item[0.19] |\lst@LeaveMode|
+%
+%       returns to the previous mode by closing a group level if and only if
+%       the current mode isn't |\lst@nomode| already. You must test yourself
+%       whether you're allowed to leave a mode, see below.
+%
+%\iffalse
+% \item[0.19] |\lst@LeaveAllModes|
+%
+%       returns to |\lst@nomode|.
+%       This is some kind of emergency macro, so don't use it!
+%\fi
+%
+% \item[0.19] |\lst@InterruptModes|
+% \item[0.19] |\lst@ReenterModes|
+%
+%       The first command returns to |\lst@nomode|, but saves the current mode
+%       sequence on a special stack. Afterwards the second macro returns to the
+%       previous mode. In between these commands you may enter any mode you
+%       want. In particular you can interrupt modes, enter some modes, and say
+%       `interrupt modes' again. Then two re-enters will take you back in front
+%       of the first `interrupt modes'.
+%
+%       Remember that |\lst@nomode| implies that \TeX's character table is
+%       active.
+% \end{syntax}
+% Some variables show the internal state of processing. You are allowed to read
+% them, but \emph{direct write access is prohibited}. Note: |\lst@ifmode| is
+% \emph{not} obsolete since there is no relation between the boolean and the
+% current mode. It will happen that we enter a mode without setting
+% |\lst@ifmode| true, and we'll set it true without assigning any mode!
+% \begin{syntax}
+% \item[0.18,,counter] |\lst@mode|
+%
+%       keeps the current mode number. Use |\ifnum\lst@mode=|\meta{mode name}
+%       to test against a mode. Don't modify the counter directly!
+%
+% \item[0.18,,boolean] |\lst@ifmode|
+%
+%       No mode change is allowed if this boolean is true---except leaving the
+%       current mode. Use |\lst@modetrue| to modify this variable, but do it
+%       only in \meta{start tokens}.
+%
+% \item[1.0,,boolean] |\lst@ifLmode|
+%
+%       Indicates whether the current mode ends at end of line.
+% \end{syntax}
+%
+%
+% \subsection{Hooks}\label{dHooks}
+%
+% Several problems arise if you want to define an aspect.
+% You should and/or must
+%   (a) find additional functionality (of general interest) and implement it,
+%   (b) create the user interface, and
+%   (c) interface with the \packagename{listings} package, i.e.~find correct
+%       hooks and insert appropriate \TeX\ material.
+% (a) is out of the scope of this developer's guide. The commands |\lstKV@...|
+% in section \ref{dHowToDefineLstAspects} might help you with (b). Here now we
+% describe all hooks of the \packagename{listings} package.
+%
+% All hooks are executed inside an overall group. This group starts somewhere
+% near the beginning and ends somewhere at the end of each listing. Don't make
+% any other assumptions on grouping. So define variables globally if it's
+% necessary---and be alert of side effects if you don't use your own groups.
+% \begin{syntax}
+% \item \hookname{AfterBeginComment}
+%
+%       is executed after the package has entered comment mode.
+%       The starting delimiter is usually typeset when the hook is called.
+%
+% \item \hookname{BoxUnsafe}
+%
+%       Contains all material to deactivate all commands and registers which
+%       are possibly unsafe inside |\hbox|. It is used whenever the package
+%       makes a box around a listing and for \packagename{fancyvrb} support.
+%
+% \item \hookname{DeInit}
+%
+%       Called at the very end of a listing but before closing the box from
+%       \hookname{BoxUnsafe} or ending a float.
+%
+% \item \hookname{DetectKeywords}
+%
+%       This \hookname{Output} subhook is executed if and only if mode changes
+%       are allowed, i.e.~if and only if the package doesn't process a comment,
+%       string, and so on---see section \ref{dInternalModes}.
+%
+% \item \hookname{DisplayStyle}
+%
+%       deactivates/activates features for displaystyle listings.
+%
+% \item \hookname{EmptyStyle}
+%
+%       Executed to select the `empty' style---except the user has redefined
+%       the style.
+%
+% \item \hookname{EndGroup}
+%
+%       Executed whenever the package closes a group, e.g.~at end of comment or
+%       string.
+%
+% \item \hookname{EOL}
+%
+%       Called at each end of \emph{input} line, right before
+%       \hookname{InitVarsEOL}.
+%
+% \item \hookname{EveryLine}
+%
+%       Executed at the beginning of each \emph{output} line, i.e.~more than
+%       once for broken lines. This hook must not change the horizontal or
+%       vertical position.
+%
+% \item \hookname{EveryPar}
+%
+%       Executed once for each input line when the output starts. This hook
+%       must not change the horizontal or vertical position.
+%
+%^^A \item \hookname{ExcludeDelims}
+%^^A
+%^^A       Executed by the \keyname{excludedelims} key before the excluded
+%^^A       delimiters are determined.
+%^^A
+% \item \hookname{ExitVars}
+%
+%       Executed right before \hookname{DeInit}.
+%
+% \item \hookname{FontAdjust}
+%
+%       adjusts font specific internal values (currently |\lst@width| only).
+%
+% \item \hookname{Init}
+%
+%       Executed once each listing to initialize things before the character
+%       table is changed. It is called after \hookname{PreInit} and before
+%       \hookname{InitVars}.
+%
+% \item \hookname{InitVars}
+%
+%       Called to init variables each listing.
+%
+% \item \hookname{InitVarsBOL}
+%
+%       initializes variables at the beginning of each input line.
+%
+% \item \hookname{InitVarsEOL}
+%
+%       updates variables at the end of each input line.
+%
+% \item \hookname{ModeTrue}
+%
+%       executed by the package when mode changes become illegal.
+%       Here keyword detection is switched off for comments and strings.
+%
+% \item \hookname{OnEmptyLine}
+%
+%       executed \emph{before} the package outputs an empty line.
+%
+% \item \hookname{OnNewLine}
+%
+%       executed \emph{before} the package starts one or more new lines,
+%       i.e.~before saying |\par\noindent\hbox{}| (roughly speaking).
+%
+% \item \hookname{Output}
+%
+%       Called before an identifier is printed.
+%       If you want a special printing style, modify |\lst@thestyle|.
+%
+% \item \hookname{OutputBox}
+%
+%       used inside each output box. Currently it is only used to make the
+%       package work together with Lambda---hopefully.
+%
+% \item \hookname{OutputOther}
+%
+%       Called before other character strings are printed.
+%       If you want a special printing style, modify |\lst@thestyle|.
+%
+% \item \hookname{PostOutput}
+%
+%       Called after printing an identifier or any other output unit.
+%
+% \item \hookname{PostTrackKeywords}
+%
+%       is a very special \hookname{Init} subhook to insert keyword tests and
+%       define keywords on demand.
+%       This hook is called after \hookname{TrackKeywords}.
+%
+% \item \hookname{PreInit}
+%
+%       Called right before \hookname{Init} hook.
+%
+% \item \hookname{PreSet}
+%
+%       Each typesetting command/environment calls this hook to initialize
+%       internals before any user supplied key is set.
+%
+% \item \hookname{SelectCharTable}
+%
+%       is executed after the package has selected the standard character
+%       table. Aspects adjust the character table here and define string and
+%       comment delimiters, and such.
+%
+% \item \hookname{SetFormat}
+%
+%       Called before internal assignments for setting a format are made.
+%       This hook determines which parameters are reset every format selection.
+%
+% \item \hookname{SetStyle}
+%
+%       Called before internal assignments for setting a style are made.
+%       This hook determines which parameters are reset every style selection.
+%
+% \item \hookname{SetLanguage}
+%
+%       Called before internal assignments for setting a language are made.
+%       This hook determines which parameters are reset every language
+%       selection.
+%
+% \item \hookname{TextStyle}
+%
+%       deactivates/activates features for textstyle listings.
+%
+% \item \hookname{TrackKeywords}
+%
+%       is a very special \hookname{Init} subhook to insert keyword tests and
+%       define keywords on demand.
+%       This hook is called before \hookname{PostTrackKeywords}.
+% \end{syntax}

+%
+% \subsection{Character tables}\label{dCharacterTables}
+%
+% Now you know how a car looks like, and you can get a driving license if you
+% take some practice. But you will have difficulties if you want to make heavy
+% alterations to the car. So let's take a closer look and come to the most
+% difficult part: the engine. We'll have a look at the big picture and fill in
+% the details step by step. For our purpose it's good to override \TeX's
+% character table. First we define a standard character table which contains
+% \begin{itemize}
+% \item letters: characters identifiers are out of,
+% \item digits: characters for identifiers or numerical constants,
+% \item spaces: characters treated as blank spaces,
+% \item tabulators: characters treated as tabulators,
+% \item form feeds: characters treated as form feed characters, and
+% \item others: all other characters.
+% \end{itemize}
+% This character table is altered depending on the current programming language.
+% We may define string and comment delimiters or other special characters.
+% Table \ref{rStdCharTable} on page \pageref{rStdCharTable} shows the standard
+% character table. It can be modified with the keys \keyname{alsoletter},
+% \keyname{alsodigit}, and \keyname{alsoother}.
+%
+% How do these `classes' work together? Let's say that the current character
+% string is `|tr|'. Then letter `|y|' simply appends the letter and we get
+% `|try|'. The next nonletter (and nondigit) causes the output of the
+% characters. Then we collect all coming nonletters until reaching a letter
+% again. This causes the output of the nonletters, and so on. Internally each
+% character becomes active in the sense of \TeX\ and is defined to do the right
+% thing, e.g.~we say
+% \begin{verbatim}
+%    \def A{\lst@ProcessLetter A}\end{verbatim}
+% where the first `|A|' is active and the second has letter catcode 11.
+% The macro |\lst@ProcessLetter| gets one token and treats it as a letter.
+% The following macros exist, where the last three get no explicit argument.
+% \begin{syntax}
+% \item[0.18] |\lst@ProcessLetter| \meta{spec.\ token}
+% \item[0.18] |\lst@ProcessDigit| \meta{spec.\ token}
+% \item[0.18] |\lst@ProcessOther| \meta{spec.\ token}
+% \item[0.18] |\lst@ProcessTabulator|
+% \item[0.18] |\lst@ProcessSpace|
+% \item[0.20] |\lst@ProcessFormFeed|
+% \end{syntax}
+% \meta{spec.\ token} is supposed to do two things. Usually it expands to
+% a printable version of the character. But if |\lst@UM| is equivalent to
+% |\@empty|, \meta{spec.\ token} must expand to a \emph{character token}.
+% For example, the sharp usually expands to |\#|, which is defined via
+% |\chardef| and is not a character token. But if |\lst@UM| is equivalent to
+% |\@empty|, the sharp expands to the character `|#|' (catcode 12). Note:
+% \emph{Changes to} |\lst@UM| \emph{must be locally.}  However, there should
+% be no need to do such basic things yourself. The \packagename{listings}
+% package provides advanced macros which use that feature,
+% e.g.~|\lst@InstallKeywords| in section \ref{dKeywordsAndWorkingIdentifiers}.
+%
+% \begin{syntax}
+% \item[0.18] |\lst@Def|\marg{character code}\meta{parameter text}\marg{definition}
+% \item[0.18] |\lst@Let|\marg{character code}\meta{token}
+%
+%       defines the specified character respectively assigns \meta{token}.
+%       The catcode table if not affected. Be careful if your definition has
+%       parameters: it is not safe to read more than one character ahead.
+%       Moreover, the argument can be \emph{arbitrary}; somtimes it's the next
+%       source code character, sometimes it's some code of the
+%       \packagename{listings} package, e.g.~|\relax|, |\@empty|, |\else|,
+%       |\fi|, and so on. Therefore don't use \TeX's ord-operator |`| on such
+%       an argument, e.g.~don't write |\ifnum`#1=65| to test against `|A|'.
+%
+%       |\lst@Def| and |\lst@Let| are relatively slow. The real definition of
+%       the standard character table differs from the following example, but it
+%       could begin with
+% \begin{verbatim}
+%    \lst@Def{9}{\lst@ProcessTabulator}
+%    \lst@Def{32}{\lst@ProcessSpace}
+%    \lst@Def{48}{\lst@ProcessDigit 0}
+%    \lst@Def{65}{\lst@ProcessLetter A}\end{verbatim}
+%
+%\iffalse
+% \item[0.20] |\lst@activecharstrue|
+% \item[0.20] |\lst@activecharsfalse|
+%
+%       control whether selecting the character table also makes all characters
+%       active (standard/extended). This is usually true and therefore default.
+%       Only the \packagename{fancyvrb} interface sets it locally false.
+%\fi
+% \end{syntax}
+% That's enough for the moment. Section \ref{dUsefulInternalDefinitions}
+% presents advanced definitions to manipulate the character table, in
+% particular how to add new comment or string types.
+%
+%
+% \subsection{On the output}
+%
+% The \packagename{listings} package uses some variables to keep the output
+% data. Write access is not recommended. Let's start with the easy ones.
+% \begin{syntax}
+% \item[0.17,,data] |\lst@lastother|
+%
+%       equals \meta{spec.\ token} version of the last processed
+%       nonidentifier-character. Since programming languages redefine the
+%       standard character table, we use the original \meta{spec.\ token}.
+%       For example, if a double quote was processed last, |\lst@lastother|
+%       is not equivalent to the macro which enters and leaves string mode.
+%       It's equivalent to |\lstum@"|, where |"| belongs to the control
+%       sequence. Remember that \meta{spec.\ token} expands either to a
+%       printable or to a token character.
+%
+%       |\lst@lastother| is equivalent to |\@empty| if such a character is not
+%       available, e.g.~at the beginning of a line. Sometimes an indentifier
+%       has already been printed after processing the last `other' character,
+%       i.e.~the character is far, far away. In this case |\lst@lastother|
+%       equals |\relax|.
+%
+% \item[0.17] |\lst@outputspace|
+%
+%       Use this predefined \meta{spec.\ token} (obviously for character code
+%       32) to test against |\lst@lastother|.
+%
+% \item[0.20] |\lstum@backslash|
+%
+%       Use this predefined \meta{spec.\ token} (for character code 92) to test
+%       against |\lst@lastother|. In the replacement text for |\lst@Def| one
+%       could write |\ifx| |\lst@lastother| |\lstum@backslash| \ldots\ to test
+%       whether the last character has been a backslash.
+%
+% \item[0.20] |\lst@SaveOutputDef|\marg{character code}\meta{macro}
+%
+%       Stores the \meta{spec.\ token} corresponding to \meta{character code}
+%       in \meta{macro}. This is the only safe way to get a correct meaning to
+%       test against |\lst@lastother|, for example
+%           |\lst@SaveOutputDef{"5C}\lstum@backslash|.
+%
+%       You'll get a ``runaway argument'' error if \meta{character code} is not
+%       between 33 and 126 (inclusive).
+% \end{syntax}
+% Now let's turn to the macros dealing a bit more with the output data and
+% state.
+% \begin{syntax}
+% \item[1.0] |\lst@XPrintToken|
+%
+%       outputs the current character string and resets it. This macro keeps
+%       track of all variables described here.
+%
+% \item[0.18,,token] |\lst@token|
+%
+%       contains the current character string. Each `character' usually
+%       expands to its printable version, but it must expand to a character
+%       token if |\lst@UM| is equivalent to |\@empty|.
+%
+% \item[0.12,,counter] |\lst@length|
+%
+%       is the length of the current character string.
+%
+% \item[0.12,,dimension] |\lst@width|
+%
+%       is the width of a single character box.
+%
+% \item[0.20,,global dimension] |\lst@currlwidth|
+%
+%       is the width of so far printed line.
+%
+% \item[0.18,,global counter] |\lst@column|
+% \item[0.12,,global counter] |\lst@pos| (nonpositive)
+%
+%       |\lst@column|$-$|\lst@pos| is the length of the so far printed line.
+%       We use two counters since this simplifies tabulator handling:
+%       |\lst@pos| is a nonpositive representative of `length of so far
+%       printed line' modulo \keyname{tabsize}.
+%       It's usually not the biggest nonpositive representative.
+%
+% \item[0.20] |\lst@CalcColumn|
+%
+%       |\@tempcnta| gets |\lst@column| $-$ |\lst@pos| $+$ |\lst@length|.
+%       This is the current column number minus one, or the current column
+%       number zero based.
+%
+% \item[0.18,,global dimension] |\lst@lostspace|
+%
+%       equals `lost' space: desired current line width minus real line width.

+%       this space to fix the column alignment.

+%
+% \subsection{Keywords and working identifiers}\label{dKeywordsAndWorkingIdentifiers}
+%
+% The \aspectname{keywords} aspect defines two main macros. Their respective
+% syntax is shown on the left. On the right you'll find examples how the
+% package actually defines some keys.
+% \begin{syntax}
+% \item[0.21]
+%   \cs{lst@InstallFamily}
+%
+%   \marg{prefix}\syntaxfill \texttt k\\
+%   \marg{name}\syntaxfill |{keywords}|\\
+%   \marg{style name}\syntaxfill |{keywordstyle}|\\
+%   \marg{style init}\syntaxfill |\bfseries|\\
+%   \marg{default style name}\syntaxfill |{keywordstyle}|\\
+%   \marg{working procedure}\syntaxfill |{}|\\
+%   \meta{\alternative{l,o}}\syntaxfill |l|\\
+%   \meta{\alternative{d,o}}\syntaxfill |d|
+%
+%       installs either a keyword or `working' class of identifiers according
+%       to whether \meta{working procedure} is empty.
+%
+%       The three keys \meta{name}, \keyname{more}\meta{name} and
+%       \keyname{delete}\meta{name}, and if not empty \meta{style name} are
+%       defined. The first order member of the latter one is initialized with
+%       \meta{style init} if not equivalent to |\relax|. If the user leaves a
+%       class style undefined, \meta{default style name} is used instead.
+%       Thus, make sure that this style is always defined. In the example,
+%       the first order keywordstyle is set to |\bfseries| and is the default
+%       for all other classes.
+%
+%       If \meta{working procedure} is not empty, this code is executed when
+%       reaching such an (user defined) identifier. \meta{working procedure}
+%       takes exactly one argument, namely the class number to which the
+%       actual identifier belongs to. If the code uses variables and requires
+%       values from previous calls, you must define these variables
+%       |\global|ly. It's not sure whether working procedures are executed
+%       inside a (separate) group or not.
+%
+%       \texttt l indicates a language key, i.e.~the lists are reset every
+%       language selection. \texttt o stands for `other' key.
+%       The keyword respectively working test is either installed at the
+%       \hookname{DetectKeyword} or \hookname{Output} hook according to
+%       \meta{\alternative{d,o}}.
+%
+% \item[0.20]
+%   \cs{lst@InstallKeywords}
+%
+%   \marg{prefix}\syntaxfill \texttt{cs}\\
+%   \marg{name}\syntaxfill |{texcs}|\\
+%   \marg{style name}\syntaxfill |{texcsstyle}|\\
+%   \marg{style init}\syntaxfill |\relax|\\
+%   \marg{default style name}\syntaxfill |{keywordstyle}|\\
+%   \marg{working procedure}\syntaxfill see below\\
+%   \meta{\alternative{l,o}}\syntaxfill |l|\\
+%   \meta{\alternative{d,o}}\syntaxfill |d|
+%
+%       Same parameters, same functionality with one execption. The macro
+%       installs exactly one keyword class and not a whole family. Therefore
+%       the argument to \meta{working procedure} is constant (currently empty).
+%
+%       The working procedure of the example reads as follows.\vspace*{-.5\baselineskip}
+% \begin{verbatim}
+%    {\ifx\lst@lastother\lstum@backslash
+%         \let\lst@thestyle\lst@texcsstyle
+%     \fi}\end{verbatim}
+%\vspace*{-.5\baselineskip}
+%       What does this procedure do? First of all it is called only if a
+%       keyword from the user supplied list (or language definition) is found.
+%       The procedure now checks for a preceding backslash and sets the output
+%       style accordingly.
+%
+%\iffalse
+% \item[0.20] |\lst@InstallTest|\marg{prefix}\syntaxbreak
+%       |\lst@|\meta{name}|@list||\lst@|\meta{name}~|\lst@g|\meta{name}|@list||\lst@g|\meta{name}\syntaxbreak
+%       |\lst@g|\meta{name}|@sty|~\meta{\alternative{w,s}}\meta{\alternative{d,o}}
+%
+%       installs a `working identifier' test or keyword style depending on
+%       \meta{\alternative{w,s}}. |\lst@g|\meta{name}|@sty| contains the
+%       working procedure or style macro. Note that the behaviour of the tests
+%       depends on the \texttt{savemem} option.
+%       The keyword respectively working test is either installed at the
+%       \hookname{DetectKeyword} or \hookname{Output} hook according to
+%       \meta{\alternative{d,o}}.
+%
+%^^A    Either each call of this macro or each different \meta{prefix} inserts
+%^^A    another test (depending on the \texttt{savemem} option).
+%
+%       |\lst@|\meta{name} contains the current identifier list and
+%       |\lst@|\meta{name}|@list| a `|\lst@|\meta{$n_i$}|\lst@g|\meta{$n_i$}'
+%       sequence of currently used classes. If no other classes are used,
+%       this equals |\lst@|\meta{name}|\lst@g|\meta{name}. The global versions
+%       |\lst@g|\ldots\ are used to keep track of the keywords.
+%       (This description needs improvement.)

+% \end{syntax}
+%
+%
+% \subsection{Delimiters}
+%
+% We describe two stages: adding a new delimiter type to an existing class of
+% delimiters and writing a new class. Each class has its name; currently exist
+% \texttt{Comment}, \texttt{String}, and \texttt{Delim}. As you know, the
+% latter and the first both provide the type \texttt l, but there is no string
+% which starts with the given delimiter and ends at end of line. So we'll add
+% it now!
+%
+% First of all we extend the list of string types by
+% \begin{verbatim}
+%    \lst@AddTo\lst@stringtypes{,l}\end{verbatim}
+% Then we must provide the macro which takes the user supplied delimiter and
+% makes appropriate definitions. The command name consists of the prefix
+% |\lst@|, the delimiter name, |DM| for using dynamic modes, and |@| followed
+% by the type.
+% \begin{verbatim}
+%    \gdef\lst@StringDM@l#1#2\@empty#3#4#5{%
+%        \lst@CArg #2\relax\lst@DefDelimB{}{}{}#3{#1}{#5\lst@Lmodetrue}}\end{verbatim}
+% You can put these three lines into a \texttt{.sty}-file or surround them by
+% |\makeatletter| and |\makeatother| in the preamble of a document.
+% And that's all!
+%{\makeatletter
+%\lst@AddTo\lst@stringtypes{,l}
+%\gdef\lst@StringDM@l#1#2\@empty#3#4#5{^^A
+%   \lst@CArg #2\relax\lst@DefDelimB{}{}{}#3{#1}{#5\lst@Lmodetrue}}
+%}
+% \begin{lstsample}{}{}
+%    \lstset{string=[l]//}
+%    \begin{lstlisting}
+%    // This is a string.
+%    This isn't a string.
+%    \end{lstlisting}
+% \end{lstsample}
+% You want more details, of course. Let's begin with the arguments.
+% \begin{itemize}
+% \item The first argument \emph{after} |\@empty| is used to start the
+%       delimiter. It's provided by the delimiter class.
+% \item The second argument \emph{after} |\@empty| is used to end the
+%       delimiter. It's also provided by the delimiter class. We didn't
+%       need it in the example, see the explanation below.
+% \item The third argument \emph{after} |\@empty| is
+%       \marg{style}\meta{start tokens}.
+%       This with a preceding |\def\lst@currstyle| is used as argument to
+%       |\lst@EnterMode|. The delimiter class also provides it. In the
+%       example we `extended' |#5| by |\lst@Lmodetrue| (line mode true).
+%       The mode automatically ends at end of line, so we didn't need the
+%       end-delimiter argument.
+% \end{itemize}
+% And now for the other arguments. In case of dynamic modes, the first argument
+% is the mode number. Then follow the user supplied  delimiter(s) whose number
+% must match the remaining arguments up to |\@empty|. For non-dynamic modes,
+% you must either allocate a static mode yourself or use a predefined mode
+% number. The delimiters then start with the first argument.
+%
+% Eventually let's look at the replacement text of the macro. The sequence
+% |\lst@CArg #2\relax| puts two required arguments after |\lst@DefDelimB|.
+% The syntax of the latter macro is
+% \begin{syntax}
+% \item[1.0] \cs{lst@DefDelimB}
+%
+%   |{|\meta{1st}\meta{2nd}\marg{rest}|}|\syntaxfill |{//{}}|\\
+%   \meta{save 1st}\syntaxfill |\lst@c/0|\\
+%   \marg{execute}\syntaxfill|{}|\\
+%   \marg{delim~exe~modetrue}\syntaxfill|{}|\\
+%   \marg{delim~exe~modefalse}\syntaxfill|{}|\\
+%   \meta{start-delimiter macro}\syntaxfill|#3|\\
+%   \meta{mode number}\syntaxfill |{#1}|\\
+%   |{|\marg{style}\meta{start tokens}|}|\syntaxfill |{#5\lst@Lmodetrue}|
+%
+%       defines \meta{1st}\meta{2nd}\meta{rest} as starting-delimiter.
+%       \meta{execute} is executed when the package comes to \meta{1st}.
+%       \meta{delim~exe~modetrue} and \meta{delim~exe~modefalse} are
+%       executed only if the whole delimiter \meta{1st}\meta{2nd}\meta{rest}
+%       is found. Exactly one of them is called depending on |\lst@ifmode|.
+%
+%       By default the package enters the mode if the delimiter is found
+%       \emph{and} |\lst@ifmode| is false. Internally we make an appropriate
+%       definition of |\lst@bnext|, which can be gobbled by placing
+%       |\@gobblethree| at the very end of \meta{delim exe modefalse}.
+%       One can provide an own definition (and gobble the default).
+%
+%       \meta{save 1st} must be an undefined macro and is used internally to
+%       store the previous meaning of \meta{1st}. The arguments \meta{2nd}
+%       and/or \meta{rest} are empty if the delimiter has strictly less than
+%       three characters. All characters of \meta{1st}\meta{2nd}\meta{rest}
+%       must already be active (if not empty).
+%       That's not a problem since the macro |\lst@CArgX| does this job.
+%   
+% \item[1.0] \cs{lst@DefDelimE}
+%
+%   |{|\meta{1st}\meta{2nd}\marg{rest}|}|\\
+%   \meta{save 1st}\\
+%   \marg{execute}\\
+%   \marg{delim~exe~modetrue}\\
+%   \marg{delim~exe~modefalse}\\
+%   \meta{end-delimiter macro}\\
+%   \meta{mode number}
+%
+%       Ditto for ending-delimiter with slight differences:
+%       \meta{delim~exe~modetrue} and \meta{delim~exe~modefalse} are executed
+%       depending on whether |\lst@mode| equals \meta{mode}.
+%
+%       The package ends the mode if the delimiter is found and |\lst@mode|
+%       equals \meta{mode}. Internally we make an appropriate definition of
+%       |\lst@enext| (not |\lst@bnext|), which can be gobbled by placing
+%       |\@gobblethree| at the very end of \meta{delim exe modetrue}.
+%
+% \item[1.0] \cs{lst@DefDelimBE}
+%
+%   followed by the same eight arguments as for |\lst@DefDelimB| and \ldots\\
+%   \meta{end-delimiter macro}
+%
+%       This is a combination of |\lst@DefDelimB| and |\lst@DefDelimE| for the
+%       case of starting and ending delimiter being the same.
+% \end{syntax}
+% We finish the first stage by examining two easy examples.
+% \texttt d-type strings are defined by
+% \begin{verbatim}
+%    \gdef\lst@StringDM@d#1#2\@empty#3#4#5{%
+%        \lst@CArg #2\relax\lst@DefDelimBE{}{}{}#3{#1}{#5}#4}\end{verbatim}
+% (and an entry in the list of string types).
+% Not a big deal. Ditto \texttt d-type comments:
+% \begin{verbatim}
+%    \gdef\lst@CommentDM@s#1#2#3\@empty#4#5#6{%
+%        \lst@CArg #2\relax\lst@DefDelimB{}{}{}#4{#1}{#6}%
+%        \lst@CArg #3\relax\lst@DefDelimE{}{}{}#5{#1}}\end{verbatim}
+% Here we just need to use both |\lst@DefDelimB| and |\lst@DefDelimE|.
+% \goodbreak
+%
+% So let's get to the second stage. For illustration, here's the definition of
+% the \texttt{Delim} class. The respective first argument to the service macro
+% makes it delete all delimiters of the class, add the delimiter, or delete
+% the particular delimiter only.
+% \begin{verbatim}
+%    \lst@Key{delim}\relax{\lst@DelimKey\@empty{#1}}
+%    \lst@Key{moredelim}\relax{\lst@DelimKey\relax{#1}}
+%    \lst@Key{deletedelim}\relax{\lst@DelimKey\@nil{#1}}\end{verbatim}
+% The service macro itself calls another macro with appropriate arguments.
+% \begin{verbatim}
+%    \gdef\lst@DelimKey#1#2{%
+%        \lst@Delim{}#2\relax{Delim}\lst@delimtypes #1%
+%                    {\lst@BeginDelim\lst@EndDelim}
+%            i\@empty{\lst@BeginIDelim\lst@EndIDelim}}\end{verbatim}
+% We have to look at those arguments. Above you can see the actual arguments
+% for the \texttt{Delim} class, below are the \texttt{Comment} class ones.
+% Note that the user supplied value covers the second and third line of
+% arguments.
+% \begin{syntax}
+% \item[0.21,,changed]
+%   \cs{lst@Delim}
+%
+%   \meta{default style macro}\syntaxfill \cs{lst@commentstyle}\\ \relax
+%   [\texttt*[\texttt*]]\texttt[\meta{type}\texttt][\texttt[\meta{style}\texttt][\texttt[\meta{type option}\texttt]]]\\
+%   \meta{delimiter\textup(s\textup)}\cs{relax}\syntaxfill|#2|\cs{relax}\\
+%   \marg{delimiter name}\syntaxfill|{Comment}|\\
+%   \meta{delimiter types macro}\syntaxfill\texttt{\cs{lst@commenttypes}}\\
+%   \alternative{\cs{@empty},\cs{@nil},\cs{relax}}\syntaxfill|#1|\\
+%   \marg{begin- and end-delim macro}\syntaxfill|{|\cs{lst@BeginComment}\cs{lst@EndComment}|}|\\
+%   \meta{extra prefix}\syntaxfill |i|\\
+%   \meta{extra conversion}\syntaxfill |\@empty|\\
+%   \marg{begin- and end-delim macro}\syntaxfill|{|\cs{lst@BeginIComment}\cs{lst@EndIComment}|}|
+%
+%   Most arguments should be clear. We'll discuss the last four. Both
+%   \marg{begin- and end-delim macro} must contain exactly two control
+%   sequences, which are given to |\lst@|\meta{name}[|DM|]|@|\meta{type}
+%   to begin and end a delimiter. These are the arguments |#3| and |#4| in our
+%   first example of |\lst@StringDM@l|. Depending on whether the user chosen
+%   type starts with \meta{extra prefix}, the first two or the last control
+%   sequences are used.
+%
+%   By default the package takes the delimiter(s), makes the characters active,
+%   and places them after |\lst@|\meta{name}[|DM|]|@|\meta{type}. If the user
+%   type starts with \meta{extra prefix}, \meta{extra conversion} might change
+%   the definition of |\lst@next| to choose a different conversion. The default
+%   is equivalent to |\lst@XConvert| with |\lst@false|.
+%
+%   Note that \meta{type} never starts with \meta{extra prefix} since it is
+%   discarded. The functionality must be fully implemented by choosing a
+%   different \marg{begin- and end-delim macro} pair.
+% \end{syntax}
+% You might need to know the syntaxes of the \meta{begin- and end-delim macro}s.
+% They are called as follows.
+% \begin{syntax}
+% \item[0.21] |\lst@Begin|\meta{whatever}
+%
+%   \marg{mode}
+%   |{|\marg{style}\meta{start tokens}|}|
+%   \meta{delimiter}|\@empty|
+%
+% \item[0.21] |\lst@End|\meta{whatever}
+%
+%   \marg{mode}
+%   \meta{delimiter}|\@empty|
+% \end{syntax}
+% The existing macros are internally defined in terms of |\lst@DelimOpen| and
+% |\lst@DelimClose|, see the implementation.
+%
+%
+% \subsection{Getting the kernel run}
+%
+% If you want new pretty-printing environments, you should be happy with
+% section \ref{rEnvironments}. New commands like |\lstinline| or
+% |\lstinputlisting| are more difficult. Roughly speaking you must follow
+% these steps.
+% \begin{enumerate}
+% \item Open a group to make all changes local.
+% \item \meta{Do whatever you want.}
+% \item Call |\lsthk@PreSet| in any case.
+% \item Now you \emph{might } want to (but need not) use |\lstset| to set some
+%       new values.
+% \item \meta{Do whatever you want.}
+% \item Execute |\lst@Init\relax| to finish initialization.
+% \item \meta{Do whatever you want.}
+% \item Eventually comes the source code, which is processed by the kernel.
+%       You must ensure that the characters are either not already read or all
+%       active. Moreover \emph{you} must install a way to detect the end of the
+%       source code. If you've reached the end, you must \ldots
+% \item \ldots\ call |\lst@DeInit| to shutdown the kernel safely.
+% \item \meta{Do whatever you want.}
+% \item Close the group from the beginning.
+% \end{enumerate}
+% For example, consider the |\lstinline| command in case of being not inside an
+% argument. Then the steps are as follows.
+% \begin{enumerate}
+% \item |\leavevmode\bgroup| opens a group.
+% \item |\def\lst@boxpos{b}| `baseline' aligns the listing.
+% \item |\lsthk@PreSet|
+% \item |\lstset{flexiblecolumns,#1}| (|#1| is the user provided
+%       key=value list)
+% \item |\lsthk@TextStyle| deactivates all features not safe here.
+% \item |\lst@Init\relax|
+% \item |\lst@Def{`#1}{\lst@DeInit\egroup}| installs the `end inline'
+%       detection, where |#1| is the next character after |\lstinline|.
+%       Moreover chr(13) is redefined to end the fragment in the same way but
+%       also issues an error message.
+% \item Now comes the source code and \ldots
+% \item \ldots\ |\lst@DeInit| (from |\lst@Def| above) ends the code snippet
+%       correctly.
+% \item Nothing.
+% \item |\egroup| (also from |\lst@Def|) closes the group.
+% \end{enumerate}
+% The real definition is different since we allow source code inside arguments.
+% Read also section \ref{iTheInputCommand} if you really want to write
+% pretty-printing commands.
+%
+%
+% \section{Useful internal definitions}\label{dUsefulInternalDefinitions}
+%
+% This section requires an update.
+%
+%
+% \subsection{General purpose macros}\label{dGeneralPurposeMacros}
+%
+% \begin{syntax}
+% \item[0.19] |\lst@AddTo|\meta{macro}\marg{\TeX~material}
+%
+%       adds \meta{\TeX~material} globally to the contents of \meta{macro}.
+%
+% \item[0.20] |\lst@Extend|\meta{macro}\marg{\TeX~material}
+%
+%       calls |\lst@AddTo| after the first token of \meta{\TeX~material} is
+%       |\expand|ed|after|. For example, |\lst@Extend \a \b| merges the
+%       contents of the two macros and stores it globally in |\a|.
+%
+% \item[0.19] |\lst@lAddTo|\meta{macro}\marg{\TeX~material}
+% \item[0.20] |\lst@lExtend|\meta{macro}\marg{\TeX~material}
+%
+%       are local versions of |\lst@AddTo| and |\lst@Extend|.
+%
+% \item[0.18] |\lst@DeleteKeysIn|\meta{macro}\meta{macro \textup(keys to remove\textup)}
+%
+%       Both macros contain a comma separated list of keys (or keywords). All
+%       keys appearing in the second macro are removed (locally) from the first.
+%
+% \item[0.19] |\lst@ReplaceIn|\meta{macro}\meta{macro \textup(containing replacement list\textup)}
+% \item[0.20] |\lst@ReplaceInArg|\meta{macro}\marg{replacement list}
+%
+%       The replacement list has the form $a_1b_1$\ldots$a_nb_n$, where each
+%       $a_i$ and $b_i$ is a character sequence (enclosed in braces if
+%       necessary) and may contain macros, but the first token of $b_i$ must
+%       not be equivalent to |\@empty|. Each sequence $a_i$ inside the first
+%       macro is (locally) replaced by $b_i$.
+%       The suffix |Arg| refers to the \emph{braced} second argument instead of
+%       a (nonbraced) macro. It's a hint that we get the `real' argument and
+%       not a `pointer' to the argument.
+%
+% \item[0.20] |\lst@IfSubstring|\marg{character sequence}\meta{macro}\marg{then}\marg{else}
+%
+%       \meta{then} is executed if \meta{character sequence} is a substring of
+%       the contents of \meta{macro}. Otherwise \meta{else} is called.
+%
+% \item[0.12] |\lst@IfOneOf|\meta{character sequence}|\relax|\meta{macro}\marg{then}\marg{else}
+%
+%       |\relax| terminates the first parameter here since it is faster than
+%       enclosing it in braces. \meta{macro} contains a comma separated list
+%       of identifiers. If the character sequence is one of these indentifiers,
+%       \meta{then} is executed, and otherwise \meta{else}.
+%
+% \item[0.21] |\lst@Swap|\marg{tok1}\marg{tok2}
+%
+%       changes places of the following two tokens or arguments \emph{without}
+%       inserting braces. For example, |\lst@Swap{abc}{def}| expands to
+%       |defabc|.
+%
+% \item[0.18] |\lst@IfNextChars|\meta{macro}\marg{then}\marg{else}
+% \item[0.19] |\lst@IfNextCharsArg|\marg{character sequence}\marg{then}\marg{else}
+%
+%       Both macros execute either \meta{then} or \meta{else} according to
+%       whether the given character sequence respectively the contents of the
+%       given macro is found (after the three arguments). Note an important
+%       difference between these macros and \LaTeX's |\@ifnextchar|:
+%       We remove the characters behind the arguments until it is possible to
+%       decide which part must be executed. However, we save these characters
+%       in the macro |\lst@eaten|, so they can be inserted using \meta{then} or
+%       \meta{else}.
+%
+% \item[0.19] |\lst@IfNextCharActive|\marg{then}\marg{else}
+%
+%       executes \meta{then} if next character is active, and \meta{else}
+%       otherwise.
+%
+% \item[0.20] |\lst@DefActive|\meta{macro}\marg{character sequence}
+%
+%       stores the character sequence in \meta{macro}, but all characters
+%       become active. The string \emph{must not} contain a begin group, end
+%       group or escape character (|{}\|); it may contain a left brace, right
+%       brace or backslash with other meaning (= catcode). This command
+%       would be quite surplus if \meta{character sequence} is not already read
+%       by \TeX\ since such catcodes can be changed easily. It is explicitly
+%       allowed that the charcaters have been read, e.g.~in
+%       |\def\test{\lst@DefActive\temp{ABC}}|!
+%
+%       Note that this macro changes |\lccode|s 0--9 without restoring them.
+%
+% \item[0.20] |\lst@DefOther|\meta{macro}\marg{character sequence}
+%
+%       stores \meta{character sequence} in \meta{macro}, but all characters
+%       have catcode 12. Moreover all spaces are removed and control sequences
+%       are converted to their name without preceding backslash. For example,
+%       |\{ Chip \}| leads to |{Chip}| where all catcodes are 12---internally
+%       the primitive |\meaning| is used.
+%
+% \iffalse
+% \item[0.19] |\lst@MakeActive|\marg{character sequence}
+%
+%       stores the character sequence in |\lst@arg| and has the same
+%       restrictions as |\lst@DefActive|. If fact, the latter definition uses
+%       this macro here.
+% \fi
+% \end{syntax}
+%
+%
+% \subsection{Character tables manipulated}\label{dCharacterTablesManipulated}
+%
+% \begin{syntax}
+% \item[0.20] |\lst@SaveDef|\marg{character code}\meta{macro}
+%
+%       Saves the current definition of the specified character in
+%       \meta{macro}. You should always save a character definition before you
+%       redefine it! And use the saved version instead of writing directly
+%       |\lst@Process|\ldots---the character could already be redefined and
+%       thus not equivalent to its standard definition.
+%
+% \item[0.20] |\lst@DefSaveDef|\marg{character code}\meta{macro}\meta{parameter text}\marg{definition}
+% \item[0.20] |\lst@LetSaveDef|\marg{character code}\meta{macro}\meta{token}
+%
+%       combine |\lst@SaveDef| and |\lst@Def| respectively |\lst@Let|.
+% \end{syntax}
+% Of course I shouldn't forget to mention \emph{where} to alter the character
+% table. Hook material at \hookname{SelectCharTable} makes permanent changes,
+% i.e.~it effects all languages. The following two keys can be used in any
+% language definition and effects the particular language only.
+% \begin{syntax}
+% \item[0.20] |SelectCharTable=|\meta{\TeX\ code}
+% \item[0.20] |MoreSelectCharTable=|\meta{\TeX\ code}
+%
+%       uses \meta{\TeX\ code} (additionally) to select the character table.
+%       The code is executed after the standard character table is selected,
+%       but possibly before other aspects make more changes. Since previous
+%       meanings are always saved and executed inside the new definition, this
+%       should be harmless.
+% \end{syntax}
+% Here come two rather useless examples. Each point (full stop) will cause a
+% message `|.|' on the terminal and in the |.log| file if language |useless| is
+% active:
+% \begin{verbatim}
+%   \lstdefinelanguage{useless}
+%       {SelectCharTable=\lst@DefSaveDef{46}% save chr(46) ...
+%            \lsts@point             % ... in \lsts@point and ...
+%            {\message{.}\lsts@point}% ... use new definition
+%       }\end{verbatim}
+% If you want to count points, you could write
+% \begin{verbatim}
+%   \newcount\lst@points % \global
+%   \lst@AddToHook{Init}{\global\lst@points\z@}
+%   \lst@AddToHook{DeInit}{\message{Number of points: \the\lst@points}}
+%   \lstdefinelanguage[2]{useless}
+%       {SelectCharTable=\lst@DefSaveDef{46}\lsts@point
+%            {\global\advance\lst@points\@ne \lsts@point}
+%       }\end{verbatim}
+% |% \global| indicates that the allocated counter is used globally. We zero
+% the counter at the beginning of each listing, display a message about the
+% current value at the end of a listing, and each processed point advances the
+% counter by one.
+%
+% \begin{syntax}
+% \item[0.21] |\lst@CArg|\meta{active characters}|\relax|\meta{macro}
+%
+%       The string of active characters is split into \meta{1st}, \meta{2nd},
+%       and \marg{rest}. If one doesn't exist, an empty argument is used. Then
+%       \meta{macro} is called with |{|\meta{1st}\meta{2nd}\marg{rest}|}| plus
+%       a yet undefined control sequence \meta{save 1st}. This macro is
+%       intended to hold the current definition of \meta{1st}, so \meta{1st}
+%       can be redefined without loosing information.
+%
+% \item[0.19] |\lst@CArgX|\meta{characters}|\relax|\meta{macro}
+%
+%       makes \meta{characters} active before calling |\lst@CArg|.
+%
+% \item[0.21] |\lst@CDef{|\meta{1st}\meta{2nd}\marg{rest}|}|\meta{save 1st}\marg{execute}\marg{pre}\marg{post}
+%
+%       should be used in connection with |\lst@CArg| or |\lst@CArgX|, i.e.~as
+%       \meta{macro} there. \meta{1st}, \meta{2nd}, and \meta{rest} must be
+%       active characters and \meta{save 1st} must be an undefined control
+%       sequence.
+%
+%       Whenever the package reaches the character \meta{1st} (in a listing),
+%       \meta{execute} is executed. If the package detects the whole string
+%       \meta{1st}\meta{2nd}\meta{rest}, we additionally execute \meta{pre},
+%       then the string, and finally \meta{post}.
+%
+% \item[0.21] |\lst@CDefX|\meta{1st}\meta{2nd}\marg{rest}\meta{save 1st}\marg{execute}\marg{pre}\marg{post}
+%
+%       Ditto except that we execute \meta{pre} and \meta{post} without the
+%       original string if we reach \meta{1st}\meta{2nd}\meta{rest}.
+%       This means that the string is replaced by \meta{pre}\meta{post} (with
+%       preceding \meta{execute}).
+% \end{syntax}
+% As the final example, here's the definition of |\lst@DefDelimB|.
+% \begin{verbatim}
+%    \gdef\lst@DefDelimB#1#2#3#4#5#6#7#8{%
+%        \lst@CDef{#1}#2%
+%            {#3}%
+%            {\let\lst@bnext\lst@CArgEmpty
+%             \lst@ifmode #4\else
+%                 #5%
+%                 \def\lst@bnext{#6{#7}{#8}}%
+%             \fi
+%             \lst@bnext}%
+%            \@empty}\end{verbatim}

+% \section{Overture}
+%
+% \paragraph{Registers}
+% For each aspect, the required numbers of registers are listed in section
+% \lstref{dPackageLoading}. Furthermore, the \packagename{keyval} package
+% allocates one token register. The macros, boxes and counters
+% |\@temp|\ldots|a|/|b|, the dimensions |\@tempdim|\ldots, and the macro
+% |\@gtempa| are also used, see the index.
+%
+% \paragraph{Naming conventions}
+% Let's begin with definitions for the user. All these public macros have
+% lower case letters and contain |lst|. Private macros and variables use the
+% following prefixes (not up-to-date?):
+% \begin{itemize}
+% \item |\lst@| for a general macro or variable,
+% \item |\lstenv@| if it is defined for the listing environment,
+% \item |\lsts@| for |s|aved character meanings,
+% \item |\lsthk@|\meta{name of hook} holds hook material,
+% \item |\lst|\meta{prefix}|@| for various kinds of keywords and working
+%       identifiers.
+% \item |\lstlang@|\meta{language}|@|\meta{dialect} contains a language and
+% \item |\lststy@|\meta{the style} contains style definition,
+% \item |\lstpatch@|\meta{aspect} to patch an aspect,
+%
+% \item |\lsta@|\meta{language}|$|\meta{dialect} contains alias,
+% \item |\lsta@|\meta{language} contains alias for all dialects of a language,
+% \item |\lstdd@|\meta{language} contains default dialect of a language
+%       (if present).
+% \end{itemize}
+% To distinguish procedure-like macros from data-macros, the name of procedure
+% macros use upper case letters with each beginning word, e.g.~|\lst@AddTo|.
+% A macro with suffix |@| is the main working-procedure for another definition,
+% for example |\lstinputlisting@| does the main work for |\lstinputlisting|.
+%
+% \paragraph{Preamble}

+%^^A \subsection{Quick `if parameter empty'}
+%^^A
+%^^A There are many situations where you have to look whether a macro parameter is empty.
+%^^A We have at least two possibilities to test |#1|, for example:
+%^^A \begin{center}
+%^^A \begin{minipage}{0.35\linewidth}
+%^^A \begin{verbatim}
+%^^A\def\test{#1}%
+%^^A\ifx \test\empty
+%^^A        % #1 is empty
+%^^A\else
+%^^A        % #1 is not empty
+%^^A\fi\end{verbatim}
+%^^A \end{minipage}
+%^^A \hskip2em\vrule\hskip2em
+%^^A \begin{minipage}{0.35\linewidth}
+%^^A \begin{verbatim}
+%^^A\ifx \empty#1\empty
+%^^A        % #1 is empty
+%^^A\else
+%^^A        % #1 is not empty
+%^^A\fi\end{verbatim}
+%^^A \end{minipage}
+%^^A \end{center}
+%^^A where |\empty| is defined by |\def\empty{}|, of course.
+%^^A The left variant should be clear and works in any case.
+%^^A The right-hand side works correct if and only if the first token of |#1| is
+%^^A not equivalent to |\empty|.
+%^^A This granted, the |\ifx| is true if and only if |#1| is empty (since |\empty|
+%^^A left from |#1| is (not) compared with |\empty| on the right).
+%^^A The two |\empty|s might be replaced by any other macro, which is not
+%^^A equivalent to the first token of the argument.
+%^^A But the definition of that macro shouldn't be too complex since this would
+%^^A slow down the |\ifx|.
+%^^A The right example needs about $45\%$ of the left's time.
+%^^A Note that this \TeX{}nique lost its importance from version 0.18 on and that
+%^^A other packages use |!| or |\relax| instead of |\empty|, for example.
+%^^A
+%^^A This \TeX nique is described in ``The \TeX book'' on page 376.

+% \subsection{Substring tests}\label{iSubstringTests}
+%
+% \lstset{language=TeX,gobble=4,xleftmargin=20pt,columns=[l]fullflexible,mathescape,keywordstyle=\ttfamily,texcsstyle=\bfseries}
+% \let\texverb\lstinline
+% \lstnewenvironment{texcode}[1][]{\lstset{#1}}{}
+% \lstset{keywords={def,key}}
+%
+% It's easy to decide whether a given character sequence is a substring of
+% another string. For example, for the substring \texverb|def| we could say
+% \begin{texcode}
+%   \def \lst@temp#1def#2\relax{%
+%       \ifx \@empty#2\@empty
+%               % "def" is not a substring
+%       \else
+%               % "def" is a substring
+%       \fi}
+%
+%   \lst@temp $\meta{another\ string}$def\relax
+% \end{texcode}
+% When \TeX\ passes the arguments |#1| and |#2|, the second is empty if
+% and only if \texverb|def| is not a substring. Without the additional
+% \texverb|def\relax|, one would get a ``runaway argument'' error if
+% \meta{another string} doesn't contain \texverb|def|.
+%
+% We use substring tests mainly in the special case of an identifier and a
+% comma separated list of keys or keywords:
+% \begin{texcode}[keywords=key]
+%   \def \lst@temp#1,key,#2\relax{%
+%       \ifx \@empty#2\@empty
+%               % `key' is not a keyword
+%       \else
+%               % `key' is a keyword
+%       \fi}
+%
+%   \lst@temp,$\meta{list\ of\ keywords}$,key,\relax
+% \end{texcode}
+% This works very well and is quite fast. But we can reduce run time in the
+% case that \texttt{key} is a keyword. Then |#2| takes the rest of the string,
+% namely all keywords after \texttt{key}.
+% Since \TeX\ inserts |#2| between the \texverb|\@empty|s, it must drop all of
+% |#2| except the first character---which is compared with \texverb|\@empty|.
+% We can redirect this rest to a third parameter:
+% \begin{texcode}[keywords=key]
+%   \def \lst@temp#1,key,#2#3\relax{%
+%       \ifx \@empty#2%
+%               % "key" is not a keyword
+%       \else
+%               % "key" is a keyword
+%       \fi}
+%
+%   \lst@temp,$\meta{list\ of\ keywords}$,key,\@empty\relax
+% \end{texcode}
+% That's a bit faster and an improvement for version 0.20.
+%
+% \begin{macro}{\lst@IfSubstring}
+% The implementation should be clear from the discussion above.
+%    \begin{macrocode}
+\def\lst@IfSubstring#1#2{%
+    \def\lst@temp##1#1##2##3\relax{%
+        \ifx \@empty##2\expandafter\@secondoftwo
+                 \else \expandafter\@firstoftwo \fi}%
+    \expandafter\lst@temp#2#1\@empty\relax}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lst@IfOneOf}
+% Ditto.
+%    \begin{macrocode}
+\def\lst@IfOneOf#1\relax#2{%
+    \def\lst@temp##1,#1,##2##3\relax{%
+        \ifx \@empty##2\expandafter\@secondoftwo
+                 \else \expandafter\@firstoftwo \fi}%
+    \expandafter\lst@temp\expandafter,#2,#1,\@empty\relax}
+%    \end{macrocode}
+% \end{macro}
+% \begin{REMOVED}
+% One day, if there is need for a case insensitive key(word) test again, we
+% can use two |\uppercase|s to normalize the first parameter:
+%    \begin{verbatim}
+%\def\lst@IfOneOfInsensitive#1\relax#2{%
+%    \uppercase{\def\lst@temp##1,#1},##2##3\relax{%
+%        \ifx \@empty##2\expandafter\@secondoftwo

+% \subsection{Catcode changes}\label{iCatcodeChanges}
+%
+% A character gets its catcode right after reading it and \TeX\ has no 
+% primitive command to change attached catcodes. However, we can replace these
+% characters by characters with same ASCII codes and different catcodes.
+% It's not the same but suffices since the result is the same.
+% Here we treat the very special case that all characters become active.
+% If we want \texverb|\lst@arg| to contain an active version of the character
+% |#1|, a prototype macro could be
+% \begin{texcode}
+%   \def\lst@MakeActive#1{\lccode`\~=`#1\lowercase{\def\lst@arg{~}}}
+% \end{texcode}
+% The |\lowercase| changes the ASCII code of |~| to the one of |#1| since we
+% have said that |#1| is the lower case version of |~|.
+% Fortunately the |\lowercase| doesn't change the catcode, so we have an active
+% version of |#1|.
+% Note that |~| is usually active.
+%
+% \begin{macro}{\lst@MakeActive}
+% We won't do this character by character.
+% To increase speed we change nine characters at the same time (if nine
+% characters are left).
+% \begin{TODO}
+% This was introduced when the delimiters were converted each listings. Now
+% this conversion is done only each language selection. So we might want to
+% implement a character by character conversion again to decrease the memory
+% usage.
+% \end{TODO}
+% We get the argument, empty |\lst@arg| and begin a loop.
+%    \begin{macrocode}
+\def\lst@MakeActive#1{%
+    \let\lst@temp\@empty \lst@MakeActive@#1%
+    \relax\relax\relax\relax\relax\relax\relax\relax\relax}
+%    \end{macrocode}
+% There are nine |\relax|es since |\lst@MakeActive@| has nine parameters and we
+% don't want any problems in the case that |#1| is empty.
+% We need nine active characters now instead of a single |~|.
+% We make these catcode changes local and define the coming macro |\global|.
+%    \begin{macrocode}
+\begingroup
+\catcode`\^^@=\active \catcode`\^^A=\active \catcode`\^^B=\active
+\catcode`\^^C=\active \catcode`\^^D=\active \catcode`\^^E=\active
+\catcode`\^^F=\active \catcode`\^^G=\active \catcode`\^^H=\active
+%    \end{macrocode}
+% First we |\let| the next operation be |\relax|.
+% This aborts our loop for processing all characters (default and possibly
+% changed later).
+% Then we look if we have at least one character.
+% If this is not the case, the loop terminates and all is done.
+%    \begin{macrocode}
+\gdef\lst@MakeActive@#1#2#3#4#5#6#7#8#9{\let\lst@next\relax
+    \ifx#1\relax
+    \else \lccode`\^^@=`#1%
+%    \end{macrocode}
+% Otherwise we say that |^^@|=chr(0) is the lower case version of the first
+% character.
+% Then we test the second character.
+% If there is none, we append the lower case |^^@| to |\lst@temp|.
+% Otherwise we say that |^^A|=chr(1) is the lower case version of the second
+% character and we test the next argument, and so on.
+%    \begin{macrocode}
+    \ifx#2\relax
+        \lowercase{\lst@lAddTo\lst@temp{^^@}}%
+    \else \lccode`\^^A=`#2%

+    \ifx#9\relax
+        \lowercase{\lst@lAddTo\lst@temp{^^@^^A^^B^^C^^D^^E^^F^^G}}%
+%    \end{macrocode}
+% If nine characters are present, we append (lower case versions of) nine
+% active characters and call this macro again via redefining |\lst@next|.
+%    \begin{macrocode}
+    \else \lccode`\^^H=`#9%
+        \lowercase{\lst@lAddTo\lst@temp{^^@^^A^^B^^C^^D^^E^^F^^G^^H}}%

+    \fi \fi \fi \fi \fi \fi \fi \fi \fi
+    \lst@next}
+\endgroup
+%    \end{macrocode}
+% This |\endgroup| restores the catcodes of chr(0)--chr(8), but not the
+% catcodes of the characters inside |\lst@MakeActive@| since they are already
+% read.
+%
+% Note: A conversion from an arbitrary `catcode--character code' table back to
+% \TeX's catcodes is possible if we test against the character codes (either
+% via |\ifnum| or |\ifcase|).
+% But control sequences and begin and end group characters definitely need
+% some special treatment.
+% However I haven't checked the details.
+% So just ignore this and don't bother me for this note. :\,--\,)

+% If an environment is used inside an argument, the listing is already read and

+% And now I have to work for it coming true.
+% Moreover we define an analogous conversion macro for the

+% \begin{syntax}

+%       appended characters are active. Since it's not a character to character
+%       conversion, `verbatim' needs to be explained. All characters can be
+%       typed in as they are except |\|, |{|, |}| and |%|. If you want one of
+%       these, you must write |\\|, |\{|, |\}| and |\%| instead.
+%       If two spaces should follow each other, the second (third, fourth,
+%       \ldots) space must be entered with a preceding backslash.
+%
+% \item[0.19] |\lst@XConvert{|\meta{\TeX\ material \textup(already read\textup)}|}|
+%
+%       \emph{appends} a `verbatim' version of the argument to |\lst@arg|.
+%       Here \TeX\ material is allowed to be put inside argument braces like
+%       |{(*}{*)}|. The contents of these arguments are converted, the braces
+%       stay as curly braces.
+%
+%       If |\lst@if| is true, each second argument is treated differently.
+%       Only the first character (of the delimiter) becomes active.
+% \end{syntax}
+%
+% \begin{macro}{\lst@InsideConvert}
+% If \texttt{mathescape} is not on, we call (near the end of this definition) a

+% \subsection{Driver file handling*}
+%
+% The \packagename{listings} package is split into several driver files,
+% miscellaneous (= aspect) files, and one kernel file.
+% All these files can be loaded partially and on demand---except the kernel
+% which provides this functionality.
+% \begin{syntax}
+% \item[0.21] |\lst@Require|\marg{name}\marg{prefix}\marg{feature list}\meta{alias}\meta{file list macro}
+%
+%       tries to load all items of \meta{feature list} from the files
+%       listed in \meta{file list macro}.
+%       Each item has the form [\oarg{sub}]\meta{feature}.
+%       |\lst@if| equals |\iftrue| if and only if all items were loadable.
+%
+%       The macro \meta{alias} gets an item as argument and must define
+%       appropriate versions of |\lst@oalias| and |\lst@malias|. In fact
+%       the feature associated with these definitions is loaded. You can
+%       use \meta{alias}=|\lst@NoAlias| for no substitution.
+%
+%       \meta{prefix} identifies the type internally and \meta{name} is used
+%       for messages.
+%
+%       For example, |\lstloadaspects| uses the following arguments where |#1|
+%       is the list of aspects: |{aspects}|\allowbreak|a|\allowbreak
+%       |{#1}|\allowbreak|\lst@NoAlias|\allowbreak|\lstaspectfiles|.
+%
+% \item[0.20] |\lst@DefDriver|\marg{name}\marg{prefix}\meta{interface macro}|\if|\alternative{true,false}
+%
+%       
+%
+% \item[0.21] |\lst@IfRequired|\oarg{sub}\marg{feature}\marg{then}\marg{else}
+%

+% \paragraph{The current position}
+% is either the dimension |\lst@currlwidth|, which is the horizontal position
+% without taking the current character string into account, or it's the current
+% column starting with number 0. This is |\lst@column| $-$ |\lst@pos| $+$
+% |\lst@length|. Moreover we have |\lst@lostspace| which is the difference
+% between the current and the desired line width. We define macros to insert
+% this lost space.
+%
+% \begin{macro}{\lst@currlwidth}
+% \begin{macro}{\lst@column}
+% \begin{macro}{\lst@pos}

+%
+% \subsection{Low- and mid-level output}
+%
+% \paragraph{Doing the output}
+% means putting the character string into a box register, updating all internal
+% data, and eventually giving the box to \TeX.
+%
+% \begin{macro}{\lst@OutputBox}
+% \begin{macro}{\lst@alloverstyle}
+% The lowest level is the output of a box register.
+% Here we use |\box#1| as argument to |\lst@alloverstyle|.
+%    \begin{macrocode}
+\def\lst@OutputBox#1{\lst@alloverstyle{\box#1}}
+%    \end{macrocode}
+% \begin{ALTERNATIVE}
+% Instead of |\global\advance\lst@currlwidth| |\wd|\meta{box number} in
+% both definitions |\lst@Kern| and |\lst@CalcLostSpaceAndOutput|, we could
+% also advance the dimension here. But I decided not to do so since it
+% simplifies possible redefinitions of |\lst@OutputBox|: we need not to care
+% about |\lst@currlwidth|.
+% \end{ALTERNATIVE}
+%    \begin{macrocode}
+\def\lst@alloverstyle#1{#1}% init
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\lst@Kern}
+% has been used to insert `lost space'.
+% It must not use |\@tempboxa| since that \ldots
+%    \begin{macrocode}
+\def\lst@Kern#1{%
+    \setbox\z@\hbox{{\lst@currstyle{\kern#1}}}%
+    \global\advance\lst@currlwidth \wd\z@
+    \lst@OutputBox\z@}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lst@CalcLostSpaceAndOutput}
+% \ldots\space is used here.
+% We keep track of |\lst@lostspace|, |\lst@currlwidth| and |\lst@pos|.
+%    \begin{macrocode}
+\def\lst@CalcLostSpaceAndOutput{%
+    \global\advance\lst@lostspace \lst@length\lst@width
+    \global\advance\lst@lostspace-\wd\@tempboxa
+    \global\advance\lst@currlwidth \wd\@tempboxa
+    \global\advance\lst@pos -\lst@length
+%    \end{macrocode}
+% Before |\@tempboxa| is output, we insert space if there is enough lost space.
+% This possibly invokes |\lst@Kern| via `insert half lost space', which is the
+% reason for why we mustn't use |\@tempboxa| above. By redefinition we prevent
+% |\lst@OutputBox| from using any special style in |\lst@Kern|.
+%    \begin{macrocode}
+    \setbox\@tempboxa\hbox{\let\lst@OutputBox\box
+        \ifdim\lst@lostspace>\z@ \lst@leftinsert \fi
+        \box\@tempboxa
+        \ifdim\lst@lostspace>\z@ \lst@rightinsert \fi}%
+%    \end{macrocode}
+% Finally we can output the new box.

+%
+% \begin{macro}{\lst@OutputToken}
+% Now comes a mid-level definition.
+% Here we use |\lst@token| to set |\@tempboxa| and eventually output the box.
+% We take care of font adjustment and special output styles.
+% Yet unknown macros are defined in the following subsections.
+%    \begin{macrocode}

+%
+%
+% \paragraph{Delaying the output}
+% means saving the character string somewhere and pushing it back when
+% neccessary. We may also attach the string to the next output box without
+% affecting style detection: both will be printed in the style of the upcoming
+% output. We will call this `merging'.
+%
+% \begin{macro}{\lst@Delay}
+% \begin{macro}{\lst@Merge}
+% To delay or merge |#1|, we process it as usual and simply save the state
+% in macros. For delayed characters we also need the currently `active'
+% output routine. Both definitions first check whether there are already
+% delayed or `merged' characters.

+%
+% \begin{macro}{\lst@CheckDelay}
+% We need to print delayed characters. The mode depends on the current output
+% macro. If it equals the saved definition, we put the delayed characters in

+% letter-to-other or other-to-letter leap. Otherwise we locally reset the
+% current character string, merge this empty string with the delayed one,
+% and output it.

+% A digit appends the character to the current character string. But we must

+\lst@AddToHook{InitVarsBOL}{\lst@whitespacetrue}
+%    \end{macrocode}
+% \end{macro}
+%
+%
+% \subsection{Whitespaces}
+%
+% Here we have to take care of two things: dropping empty lines at the end of
+% a listing and the different column formats. Both use |\lst@lostspace|. Lines
+% containing only tabulators and spaces should be viewed as empty. In order to
+% achieve this, tabulators and spaces at the beginning of a line don't output
+% any characters but advance |\lst@lostspace|. Whenever this dimension is
+% positive we insert that space before the character string is output. Thus,
+% if there are only tabulators and spaces, the line is `empty' since we
+% haven't done any output.
+%
+% We have to do more for flexible columns. Whitespaces can fix the column
+% alignment: if the real line is wider than expected, a tabulator is at least
+% one space wide; all remaining space fixes the alignment. If there are two or
+% more space characters, at least one is printed; the others fix the column
+% alignment.
+%
+%
+% \paragraph{Tabulators}
+% are processed in three stages. You have already seen the last stage
+% |\lst@GotoTabStop|. The other two calculate the necessary width and take care
+% of visible tabulators and spaces.
+%
+% \begin{lstkey}{tabsize}
+% We check for a legal argument before saving it. Default tabsize is 8 as
+% proposed by \lsthelper{Rolf~Niepraschk}{1997/04/24}{tabsize=8}.
+%    \begin{macrocode}
+\lst@Key{tabsize}{8}
+    {\ifnum#1>\z@ \def\lst@tabsize{#1}\else
+         \PackageError{Listings}{Strict positive integer expected}%
+         {You can't use `#1' as tabsize. \@ehc}%
+     \fi}
+%    \end{macrocode}
+% \end{lstkey}
+%
+% \begin{lstkey}{showtabs}
+% \begin{lstkey}{tab}
+% Two more user keys for tab control.
+%    \begin{macrocode}
+\lst@Key{showtabs}f[t]{\lstKV@SetIf{#1}\lst@ifshowtabs}
+\lst@Key{tab}{\kern.06em\hbox{\vrule\@height.3ex}%
+              \hrulefill\hbox{\vrule\@height.3ex}}
+    {\def\lst@tab{#1}}
+%    \end{macrocode}
+% \end{lstkey}
+% \end{lstkey}
+%
+% \begin{macro}{\lst@ProcessTabulator}
+% A tabulator outputs the preceding characters, which decrements |\lst@pos| by
+% the number of printed characters.
+%    \begin{macrocode}
+\def\lst@ProcessTabulator{%
+    \lst@XPrintToken \lst@whitespacetrue
+%    \end{macrocode}
+% Then we calculate how many columns we need to reach the next tabulator stop:
+% we add |\lst@tabsize| until |\lst@pos| is strict positive. In other words,
+% |\lst@pos| is the column modulo |tabsize| and we're looking for a positive
+% representative. We assign it to |\lst@length| and reset |\lst@pos| in the
+% submacro.
+%    \begin{macrocode}
+    \global\advance\lst@column -\lst@pos
+    \@whilenum \lst@pos<\@ne \do

+% \subsection{Character tables}\label{iCharacterTables}
+%
+%
+% \subsubsection{The standard table}
+%
+% The standard character table is selected by |\lst@SelectStdCharTable|, which
+% expands to a token sequence 
+%    \ldots|\def| |A{\lst@ProcessLetter| |A}|\ldots\space
+% where the first A is active and the second has catcode 12. We use the
+% following macros to build the character table.
+% \begin{syntax}
+% \item[0.19] |\lst@CCPut|\meta{class macro}\meta{$c_1$}\ldots\meta{$c_k$}|\z@|
+%
+%       extends the standard character table by the characters with codes
+%       \meta{$c_1$}\ldots\meta{$c_k$} making each character use
+%       \meta{class macro}. All these characters must be printable via
+%       |\char|\meta{$c_i$}.
+%
+% \item[0.20] |\lst@CCPutMacro|\meta{class$_1$}\meta{$c_1$}\meta{definition$_1$}\ldots|\@empty\z@\@empty|
+%
+%       also extends the standard character table: the character \meta{$c_i$}
+%       will use \meta{class$_i$} and is printed via \meta{definition$_i$}.
+%       These definitions must be \meta{spec. token}s in the sense of section
+%       \ref{dCharacterTables}.
+% \end{syntax}
+%
+% \begin{macro}{\lst@Def}
+% \begin{macro}{\lst@Let}
+% For speed we won't use these helpers too often.
+%    \begin{macrocode}
+\def\lst@Def#1{\lccode`\~=#1\lowercase{\def~}}

+% The definition of the space below doesn't hurt anything. But other aspects,
+% for example \aspectname{lineshape} and \aspectname{formats}, redefine also
+% the macro |\space|. Now, if \LaTeX\ calls |\try@load@fontshape|, the |.log|
+% messages would show some strange things since \LaTeX\ uses |\space| in these
+% messages. The following addition ensures that |\space| expands to a space
+% and not to something different. This was one more bug reported by
+% \lsthelper{Denis~Girou}{1999/09/16}{bad font info message with breaklines}.

+% \end{macro}
+%
+% \begin{macro}{\lst@CCPutMacro}
+% Now we come to a delicate point. The characters not inserted yet aren't
+% printable (|_|, |$|, \ldots) or aren't printed well (|*|, |-|, \ldots) if we
+% enter these characters. Thus we use proper macros to print the characters.
+% Works perfectly. The problem is that the current character string is
+% printable for speed, for example |_| is already replaced by a macro version,
+% but the new keyword tests need the original characters.
+%
+% The solution: We define |\def _{\lst@ProcessLetter\lst@um_}| where the first
+% underscore is active and the second belongs to the control sequence.
+% Moreover we have |\def\lst@um_{\lst@UM _}| where the second underscore has
+% the usual meaning. Now the keyword tests can access the original character
+% simply by making |\lst@UM| empty. The default definition gets the following
+% token and builds the control sequence |\lst@um_@|, which we'll define to
+% print the character. Easy, isn't it?^^A ;-)
+%
+% The following definition does all this for us. The first parameter gives the
+% character class, the second the character code, and the last the definition
+% which actually prints the character. We build the names |\lst@um_| and
+% |\lst@um_@| and give them to a submacro.
+%    \begin{macrocode}
+\def\lst@CCPutMacro#1#2#3{%
+    \ifnum#2=\z@ \else

+        \expandafter\lst@CCPutMacro
+    \fi}
+%    \end{macrocode}
+% The arguments are now |\lst@um_|, |\lst@um_@|, nonactive character, active
+% character, character class and printing definition. We add |\def _{|
+% |\lst@ProcessLetter| |\lst@um_}| to |\lst@SelectStdCharTable| (and similarly

+%
+% \subsubsection{Catcode problems}
+%
+% \begin{macro}{\lst@nfss@catcodes}
+% \lsthelper{Anders~Edenbrandt}{1997/04/22}{preload of .fd files} found a bug
+% with \texttt{.fd}-files. Since we change catcodes and these files are read
+% on demand, we must reset the catcodes before the files are input. We use a
+% local redefinition of |\nfss@catcodes|.
+%    \begin{macrocode}
+\lst@AddToHook{Init}
+    {\let\lsts@nfss@catcodes\nfss@catcodes
+     \let\nfss@catcodes\lst@nfss@catcodes}
+%    \end{macrocode}
+% The |&|-character had turned into |\&| after a bug report by \lsthelper
+% {David~Aspinall}{2003/07/17}{loading of .fd file inside tabular produces
+% error}.
+%    \begin{macrocode}
+\def\lst@nfss@catcodes{%

+    \@makeother =\lsts@nfss@catcodes}
+%    \end{macrocode}
+% The investigation of a bug reported by \lsthelper{Christian~Gudrian}
+% {2000/11/16}{problems with mathpple} showed that the equal sign needs
+% to have `other' catcode, as assigned above.
+% \lsthelper{Svend~Tollak~Munkejord}{2002/04/17}{package incompatible with
+%  Lucida .fd files} reported problems with Lucida .fd-files, while
+% \lsthelper{Heiko~Oberdiek}{2002/04/17}{Re: listings fails with Lucida
+% font} analysed the bug, which above led to the line starting with
+% |\@makeaother (|.
+%
+% The name of |\lst@makeletter| is an imitation of \LaTeX's |\@makeother|.
+%    \begin{macrocode}
+\def\lst@makeletter#1{%
+    \ifx\relax#1\else\catcode`#111\relax \expandafter\lst@makeletter\fi}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{lstkey}{useoutput}
+% \begin{macro}{\output}
+% Another problem was first reported by \lsthelper{Marcin~Kasperski}
+% {1999/04/28}{listings spoil toc}. It is also catcode related and
+% \lsthelper{Donald~Arseneau}{1999/05/13}{comp.text.tex Re: delayed write and
+% catcode changes} let me understand it. The point is that \TeX\ seems to use
+% the \emph{currently} active catcode table when it writes non-|\immediate|
+% |\write|s to file and not the catcodes involved when \emph{reading} the
+% characters.
+% So a section heading |\L a| was written |\La| if a listing was split on two
+% pages since a non-standard catcode table was in use when writing |\La| to
+% file, the previously attached catcodes do not matter. One more bug was that
+% accents in page headings or footers were lost when a listing was split on
+% two pages. \lsthelper{Denis~Girou}{1999/08/03}{Accents lost in heading if
+% listing split on two pages} found this latter bug. A similar problem with
+% the tilde was reported by \lsthelper{Thorsten~Vitt}{2001/06/25}{fancyhdr +
+% listings crossing pages ==> ~ in header, not space}.
+%
+% We can choose between three possibilities.
+% \lsthelper{Donald~Arseneau}{2006/09/14}{cannot select output routine 1}
+% noted a bug here in the |\ifcase| argument.
+%    \begin{macrocode}
+\lst@Key{useoutput}{2}{\edef\lst@useoutput{\ifcase0#1 0\or 1\else 2\fi}}
+%    \end{macrocode}
+% The first does not modify the existing output routine.
+%    \begin{macrocode}
+\lst@AddToHook{Init}
+{\edef\lst@OrgOutput{\the\output}%
+\ifcase\lst@useoutput\relax
+\or
+%    \end{macrocode}
+% The second possibility is as follows: We interrupt the current modes---in
+% particular |\lst@Pmode| with modified catcode table---, call the original
+% output routine and reenter the mode. This must be done with a little care.
+% First we have to close the group which \TeX\ opens at the beginning of the
+% output routine. A single |\egroup| gives an `unbalanced output routine'
+% error. But |\expandafter\egroup| works. Again it was
+% \lsthelper{Donald~Arseneau}{2001/01/10}{comp.text.tex Re: \output puzzle}
+% who gave the explaination: The |\expandafter| set the token type of |\bgroup|
+% to |backed_up|, which prevents \TeX's from recovering from an unbalanced
+% output routine. \lsthelper{Heiko~Oberdiek}{2001/01/05}{comp.text.tex Re:
+% \output puzzle} reported that |\csname| |egroup||\endcsname| does the trick,
+% too.
+%
+% However, since \TeX\ checks the contents of |\box| 255 when we close the
+% group (`output routine didn't use all of |\box| 255'), we have to save it
+% temporaryly.
+%    \begin{macrocode}
+ \output{\global\setbox\lst@gtempboxa\box\@cclv
+         \expandafter\egroup
+%    \end{macrocode}
+% Now we can interrupt the mode, but we have to save the current character
+% string and the current style.
+%    \begin{macrocode}
+         \lst@SaveToken
+     \lst@InterruptModes
+%    \end{macrocode}
+% We restore the contents, use the original output routine, and \ldots
+%    \begin{macrocode}
+     \setbox\@cclv\box\lst@gtempboxa
+     \bgroup\lst@OrgOutput\egroup
+%    \end{macrocode}
+% \ldots\space open a group matching the |}| which \TeX\ inserts at the end of
+% the output routine. We reenter modes and restore the character string and
+% style |\aftergroup|. Moreover we need to reset |\pagegoal|---added after a
+% bug report by \lsthelper{Jochen~Schneider}{2002/03/09}{de.comp.text.tex:
+% Problem mit Listings-Paket 1.0-Beta; unmotivated pagebreak with preceding
+% float}.
+%    \begin{macrocode}
+     \bgroup
+     \aftergroup\pagegoal\aftergroup\vsize
+     \aftergroup\lst@ReenterModes\aftergroup\lst@RestoreToken}%
+\else
+%    \end{macrocode}
+% The third option is to restore all catcodes and meanings inside a modified
+% output routine and to call the original routine afterwards.
+%    \begin{macrocode}
+ \output{\lst@RestoreOrigCatcodes
+         \lst@ifec \lst@RestoreOrigExtendedCatcodes \fi
+         \lst@OrgOutput}%
+\fi}
+%    \end{macrocode}
+% Note that this output routine isn't used too often. It is executed only if
+% it's possible that a listing is split on two pages: if a listing ends at
+% the bottom or begins at the top of a page, or if a listing is really split.
+% \end{macro}
+% \end{lstkey}
+%
+% \begin{macro}{\lst@GetChars}
+% \begin{macro}{\lst@ScanChars}
+% \begin{lstkey}{rescanchars}
+% To make the third |\output|-option work, we have to scan the catcodes and
+% also the meanings of active characters:
+%    \begin{macrocode}
+\def\lst@GetChars#1#2#3{%
+    \let#1\@empty
+    \@tempcnta#2\relax \@tempcntb#3\relax
+    \loop \ifnum\@tempcnta<\@tempcntb\relax

+        \fi
+        \advance\@tempcnta\@ne
+    \repeat}
+%    \end{macrocode}
+% As per a bug report by \lsthelper{Benjamin~Lings}{2004/10/15}%
+% {\usepackage{xy,listings} yields: "Forbidden control sequence...."}, we
+% deactivate |\outer| definition of |^^L| temporarily (inside and outside
+% of |\lst@ScanChars|) and restore the catcode at end of package via the
+% |\lst@RestoreCatcodes| command.

+% \subsubsection{Adjusting the table}
+%
+% We begin with modifiers for the basic character classes.
+%
+% \begin{lstkey}{alsoletter}
+% \begin{lstkey}{alsodigit}
+% \begin{lstkey}{alsoother}
+% The macros |\lst@also|\ldots\space will hold |\def|\meta{char}|{|\ldots|}|

+% Now we get to the more powerful definitions.
+%
+% \begin{macro}{\lst@CDef}
+% Here we unfold the first parameter \meta{1st}\marg{2nd}\marg{rest} and say
+% that this input string is `replaced' by \meta{save 1st}\marg{2nd}^^A
+% \marg{rest}---plus \meta{execute}, \meta{pre}, and \meta{post}. This main

+\def\lst@CDefX@#1#2#3{\lst@CDefIt#1{#2}{#3}{}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lst@CDefIt}
+% is the main working procedure for the previous macros. It redefines the
+% sequence |#1#2#3| of characters. At least |#1| must be active; the other two
+% arguments might be empty, not equivalent to empty!
+%    \begin{macrocode}
+\def\lst@CDefIt#1#2#3#4#5#6#7#8{%
+    \ifx\@empty#2\@empty
+%    \end{macrocode}
+% For a single character we just execute the arguments in the correct order.
+% You might want to go back to section \ref{dCharacterTablesManipulated} to
+% look them up.
+%    \begin{macrocode}
+        \def#1{#6\def\lst@next{#7#4#8}\lst@next}%
+    \else \ifx\@empty#3\@empty
+%    \end{macrocode}
+% For a two character sequence we test whether \meta{pre} and \meta{post}
+% must be executed.
+%    \begin{macrocode}

+            \lst@next}%
+    \else
+%    \end{macrocode}
+% We do the same for an arbitrary character sequence---except that we have to
+% use |\lst@IfNextCharsArg| instead of |\ifx|\ldots|\fi|.
+%    \begin{macrocode}
+        \def#1{%
+            #6%
+            \lst@IfNextCharsArg{#2#3}{#7#4#8}%

+    \fi \fi}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lst@CArgX}
+% We make |#1#2| active and call |\lst@CArg|.
+%    \begin{macrocode}
+\def\lst@CArgX#1#2\relax{%
+    \lst@DefActive\lst@arg{#1#2}%
+    \expandafter\lst@CArg\lst@arg\relax}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lst@CArg}
+% arranges the first two arguments for |\lst@CDef|[|X|]. We get an undefined
+% macro and use |\@empty\@empty\relax| as delimiter for the submacro.
+%    \begin{macrocode}
+\def\lst@CArg#1#2\relax{%
+    \lccode`\/=`#1\lowercase{\def\lst@temp{/}}%
+    \lst@GetFreeMacro{lst@c\lst@temp}%
+    \expandafter\lst@CArg@\lst@freemacro#1#2\@empty\@empty\relax}
+%    \end{macrocode}
+% Save meaning of \meta{1st}=|#2| in \meta{save 1st}=|#1| and call the macro
+% |#6| with correct arguments. From version 1.0 on, |#2|, |#3| and |#4|
+% (respectively empty arguments) are tied together with group braces.
+% This allows us to save two arguments in other definitions, for example in
+% |\lst@DefDelimB|.
+%    \begin{macrocode}
+\def\lst@CArg@#1#2#3#4\@empty#5\relax#6{%
+    \let#1#2%
+    \ifx\@empty#3\@empty

+    \else
+        \def\lst@next{#6{#2#3{#4}}}%
+    \fi
+    \lst@next #1}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lst@CArgEmpty}
+% `executes' an |\@empty|-delimited argument. We will use it for the delimiters.
+%    \begin{macrocode}
+\def\lst@CArgEmpty#1\@empty{#1}
+%    \end{macrocode}
+% \end{macro}
+%
+%
+% \subsection{Delimiters}
+%
+% Here we start with general definitions common to all delimiters.
+%
+% \begin{lstkey}{excludedelims}
+% controls which delimiters are not printed in \meta{whatever}style. We just
+% define |\lst@ifex|\meta{whatever} to be true. Such switches are set false
+% in the \hookname{ExcludeDelims} hook and are handled by the individual
+% delimiters.
+%    \begin{macrocode}
+\lst@Key{excludedelims}\relax
+    {\lsthk@ExcludeDelims \lst@NormedDef\lst@temp{#1}%
+     \expandafter\lst@for\lst@temp\do
+     {\expandafter\let\csname\@lst @ifex##1\endcsname\iftrue}}
+%    \end{macrocode}
+% \end{lstkey}
+%
+% \begin{macro}{\lst@DelimPrint}
+% And this macro might help in doing so. |#1| is |\lst@ifex|\meta{whatever}
+% (plus |\else|) or just |\iffalse|, and |#2| will be the delimiter. The
+% temporary mode change ensures that the characters can't end the current
+% delimiter or start a new one.
+%    \begin{macrocode}
+\def\lst@DelimPrint#1#2{%
+    #1%
+      \begingroup
+        \lst@mode\lst@nomode \lst@modetrue
+        #2\lst@XPrintToken
+      \endgroup
+      \lst@ResetToken
+    \fi}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lst@DelimOpen}
+% We print preceding characters and the delimiter, enter the appropriate mode,
+% print the delimiter again, and execute |#3|. In fact, the arguments |#1| and
+% |#2| will ensure that the delimiter is printed only once.
+%    \begin{macrocode}
+\def\lst@DelimOpen#1#2#3#4#5#6\@empty{%
+    \lst@TrackNewLines \lst@XPrintToken
+    \lst@DelimPrint#1{#6}%
+    \lst@EnterMode{#4}{\def\lst@currstyle#5}%
+    \lst@DelimPrint{#1#2}{#6}%
+    #3}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lst@DelimClose}
+% is the same in reverse order.
+%    \begin{macrocode}
+\def\lst@DelimClose#1#2#3\@empty{%
+    \lst@TrackNewLines \lst@XPrintToken
+    \lst@DelimPrint{#1#2}{#3}%
+    \lst@LeaveMode
+    \lst@DelimPrint{#1}{#3}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lst@BeginDelim}
+% \begin{macro}{\lst@EndDelim}
+% These definitions are applications of |\lst@DelimOpen| and |\lst@DelimClose|:
+% the delimiters have the same style as the delimited text.
+%    \begin{macrocode}
+\def\lst@BeginDelim{\lst@DelimOpen\iffalse\else{}}
+\def\lst@EndDelim{\lst@DelimClose\iffalse\else}
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\lst@BeginIDelim}
+% \begin{macro}{\lst@EndIDelim}
+% Another application: no delimiter is printed.
+%    \begin{macrocode}
+\def\lst@BeginIDelim{\lst@DelimOpen\iffalse{}{}}
+\def\lst@EndIDelim{\lst@DelimClose\iffalse{}}
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\lst@DefDelims}
+% This macro defines all delimiters and is therefore reset every language
+% selection.
+%    \begin{macrocode}
+\lst@AddToHook{SelectCharTable}{\lst@DefDelims}
+\lst@AddToHookExe{SetLanguage}{\let\lst@DefDelims\@empty}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lst@Delim}
+% First we set default values: no |\lst@modetrue|, cumulative style, and no
+% argument to |\lst@Delim|[|DM|]|@|\meta{type}.
+%    \begin{macrocode}
+\def\lst@Delim#1{%
+    \lst@false \let\lst@cumulative\@empty \let\lst@arg\@empty
+%    \end{macrocode}
+% These are the correct settings for the double-star-form, so we immediately
+% call the submacro in this case. Otherwise we either just suppress cumulative
+% style, or even indicate the usage of |\lst@modetrue| with |\lst@true|.
+%    \begin{macrocode}
+    \@ifstar{\@ifstar{\lst@Delim@{#1}}%
+                     {\let\lst@cumulative\relax
+                      \lst@Delim@{#1}}}%
+            {\lst@true\lst@Delim@{#1}}}
+%    \end{macrocode}

+% \begin{macro}{\lst@MakeCaption}
+% Before defining this macro, we ensure that some other control sequences
+% exist---\lsthelper{Adam~Prugel-Bennett}{2001/02/19}{\abovecaptionskip
+% undefined in slides.cls} reported problems with the slides document class.
+% In particular we allocate above- and belowcaption skip registers and define
+% |\@makecaption|, which is an exact copy of the definition in the article
+% class. To respect the LPPL: you should have a copy of this class on your
+% \TeX\ system or you can obtain a copy from the CTAN, e.g.~from the ftp-server
+% \texttt{ftp.dante.de}.
+%
+% Axel Sommerfeldt proposed a couple of improvements regarding captions and
+% titles. The first is to separate the definitions of the skip registers and
+% |\@makecaption|.
+%    \begin{macrocode}
+\@ifundefined{abovecaptionskip}
+{\newskip\abovecaptionskip
+ \newskip\belowcaptionskip}{}
+\@ifundefined{@makecaption}

+   \else
+     \global \@minipagefalse
+     \hb@xt@\hsize{\hfil\box\@tempboxa\hfil}%
+   \fi
+   \vskip\belowcaptionskip}%
+}{}
+%    \end{macrocode}
+% The introduction of |\fnum@lstlisting| is also due to Axel. Previously the
+% replacement text was used directly in |\lst@MakeCaption|. A |\noindent| has
+% been moved elsewhere and became |\@parboxrestore| after a bug report from
+% \lsthelper{Frank~Mittelbach}{2004/02/13}{Re: Info: Inkompatibilit\"at

+% \lsthelper{Axel~Sommerfeldt}{2004/02/27}{Re: caption + listings + hyperref}
+% for analyzing the bug.
+% We |\refstepcounter| the listing counter if and only if |\lst@@caption| is

+% been inserted here after a bug report from \lsthelper{Werner~Struckmann}
+% {2003/06/25}{undefined control sequence \lst@name}.

+% We make a caption if and only if the caption is not empty and the user

+% pagebreaks between caption (or title) and a listing, we redefine the

+% pagebreaks in front of a `top-caption' and after a `bottom-caption'.
+% Also, the |\ignorespaces| in the |\@makecaption| call is added to match
+% what \LaTeX\ does in |\@caption|; the AMSbook class (and perhaps others)
+% assume this is present and attempt to strip it off when testing for an
+% empty caption, causing a bug noted by \lsthelper{Xiaobo~Peng}{2006/06/29}%

+% {2001/07/30}{inconsistent `break' when \lstinline is used inside caption}
+% reported a problem which has gone after removing |\let| |\lst@newlines|
+% |\@empty| (now |\lst@newlines| is a counter!). Unfortunately I don't know

+%
+% \begin{macro}{\lst@add@special}
+% This helper macro adds its argument to the
+% |\dospecials| macro which is conventionally used by verbatim macros
+% to alter the catcodes of the currently active characters.  We need
+% to add |\do\|\meta{c} to the expansion of |\dospecials| after
+% removing the character if it was already there to avoid multiple
+% copies building up should |\lstMakeShortInline| not be balanced by
+% |\lstDeleteShortInline| (in case anything that uses |\dospecials|

+% Similarly we have to add |\@makeother\|\meta{c} to |\@sanitize|
+% (which is used in things like "\index" to re-catcode all special
+% characters except braces).
+%    \begin{macrocode}
+  \expandafter\gdef\expandafter\@sanitize\expandafter

+%    \end{macrocode}

+% \begin{macro}{\lst@rem@special}
+% The inverse of |\lst@add@special| is slightly trickier.  |\do| is
+% re-defined to expand to nothing if its argument is the character of
+% interest, otherwise to expand simply to the argument.  We can then
+% re-define |\dospecials| to be the expansion of itself.  The space
+% after |=`##1| prevents an expansion to |\relax|!
+%    \begin{macrocode}
+\def\lst@rem@special#1{%

+    \ifnum`#1=`##1 \else \noexpand\do\noexpand##1\fi}%
+  \xdef\dospecials{\dospecials}%
+%    \end{macrocode}
+% Fixing |\@sanitize| is the same except that we need to re-define
+% |\@makeother| which obviously needs to be done in a group. 
+%    \begin{macrocode}
+  \begingroup
+    \def\@makeother##1{%
+      \ifnum`#1=`##1 \else \noexpand\@makeother\noexpand##1\fi}%

+% \end{macro}
+%
+% \begin{macro}{\lstenv@ProcessJ}
+% Now comes the horrible scenario: a listing inside an argument. We've
+% already worked in section \ref{iApplicationsTo} for this. Here we must get
+% all characters up to `end environment'. We distinguish the cases `command
+% fashion' and `true environment'.
+%    \begin{macrocode}

+% The first case is pretty simple: The code is terminated by

+% We must append an active backslash and the `end string' to |\lst@arg|. So all
+% (in fact most) other processing won't notice that the code has been inside
+% an argument. But the EOL character is chr(10)=|^^J| now and not chr(13).

+}\endgroup
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\lstenv@ProcessJEnv}
+% The `true environment' case is more complicated. We get all characters up to

+    \else

+% Otherwise we append the characters including the eaten |\end| and the eaten
+% argument to current |\lst@arg|. And we look for the end of environment again.
+%    \begin{macrocode}

+%
+% \begin{macro}{\lstenv@backslash}

+% \subsubsection{Defining new environments}
+%
+% \begin{macro}{\lstnewenvironment}
+% Now comes the main command. We define undefined environments only. On the

+% following example 20.5 on page 204 of `The \TeX book'.

+\def\@tempa#1#2#3{%
+\gdef\lstnewenvironment@##1##2##3##4##5{%
+    \begingroup
+%    \end{macrocode}
+% A lonely `end environment' produces an error.
+%    \begin{macrocode}
+    \global\@namedef{end##2}{\lstenv@Error{##2}}%
+%    \end{macrocode}
+% The `main' environment macro defines the environment name for later use and
+% calls a submacro getting all arguments. We open a group and make EOL active.

+% \item[0.19]
+%   |\begin{lstsample}|\marg{point list}\marg{left}\marg{right}
+%
+%   \leavevmode\hspace*{-\leftmargini}|\end{lstsample}|
+%
+%       Roughly speaking all material in between this environment is executed
+%       `on the left side' and typeset verbatim on the right. \meta{left} is
+%       executed before the left side is typeset, and similarly \meta{right}
+%       before the right-hand side.
+%
+%       \meta{point list} is used as argument to the \keyname{point} key.
+%       This is a special key used to highlight the keys in the examples.
+%
+% \item[1.0]
+%   |\begin{lstxsample}|\marg{point list}
+%
+%   \leavevmode\hspace*{-\leftmargini}|\end{lstxsample}|
+%
+%       The material in between is (a) added to the left side of the next
+%       \texttt{lstsample} environment and (b) typeset verbatim using the
+%       whole line width.
+%
+% \item[0.21] |\newdocenvironment|\marg{name}\marg{short name}\marg{begin code}\marg{end code}
+%
+%       The \meta{name} environment can be used in the same way as `macro'.
+%       The provided(!) definitions
+%           |\Print|\meta{short name}|Name|
+%       and |\SpecialMain|\meta{short name}|Index|
+%       control printing in the margin and indexing as the defaults
+%       |\PrintMacroName| and |\SpecialMainIndex| do.
+%
+%       This command is used to define the `aspect' and `lstkey' environments.
+%
+%\item[0.21] \texttt{macroargs} environment
+%
+%       This `enumerate' environment uses as labels `|#1| =', `|#2| =',
+%       and so on.
+%
+% \item \texttt{TODO} environment
+% \item \texttt{ALTERNATIVE} environment
+% \item \texttt{REMOVED} environment
+% \item \texttt{OLDDEF} environment
+%
+%       These environments enclose comments on `to do's', alternatives and
+%       removed or old definitions.
+%
+% \item[0.21] |\lstscanlanguages|\meta{list macro}\marg{input files}\marg{don't input}
+%
+%       scans \marg{input files}$\setminus$\marg{don't input} for language
+%       definitions. The available languages are stored in \meta{list macro}
+%       using the form \meta{language}|(|\meta{dialtect}|),|.
+%
+% \item[0.21] |\lstprintlanguages|\meta{list macro}
+%
+%       prints the languages in two column format.

+% \section{History}
+% \begingroup\small
+% Only major changes are listed here. Introductory version numbers of commands
+% and keys are in the sources of the guides, which makes this history fairly
+% short.
+% \renewcommand\labelitemi{--}
+% \begin{itemize}
+% \item[0.1] from 1996/03/09
+%   \item test version to look whether package is possible or not

+%\fi
+%   \item load on demand: language specific macros moved to driver files
+%   \item comments are declared now and not implemented for each language again
+%         (this makes the \TeX\ sources easier to read)
+% \item[0.14] from 1997/02/18
+%   \item User's guide rewritten, Implementation guide uses macro environment
+%   \item (non) case sensitivity implemented and multiple string types,
+%         i.e.~Modula-2 handles both string types: quotes and double quotes
+%\iffalse
+%   \item comment declaration is user-accessible
+%   \item package compatible to \verb!german.sty!
+%\fi
+% \item[0.15] from 1997/04/18
+%\iffalse
+%   \item additional languages: Java, Turbo Pascal
+%\fi

+% \item[0.16] from 1997/06/01
+%\iffalse
+%   \item changed `$<$' to `$>$' in |\lst@SkipToFirst|

+%\fi
+%   \item listing environment rewritten
+% \item[0.17] from 1997/09/29
+%\iffalse
+%   \item |\spreadlisting| works correct now (e.g.~page numbers don't move right)
+%\fi
+%   \item speed up things (quick `if parameter empty', all |\long| except one
+%         removed, faster \verb!\lst@GotoNextTabStop!, etc.)
+%   \item improved alignment of wide other characters (e.g.~$==$)
+%\iffalse
+%   \item many new languages: Ada, Algol, Cobol, Comal 80, Elan, Fortran 77,
+%         Lisp, Logo, Matlab, Oberon, Perl, PL/I, Simula, SQL, \TeX
+%\fi
+% \item[pre-0.18] from 1998/03/24 (unpublished)
+%\iffalse
+%   \item bug concerning |\labelstyle| (becomes \keyname{numberstyle}) removed

+%\fi
+%   \item experimental implementation of character classes
+% \item[0.19] from 1998/11/09
+%   \item character classes and new \lst-aspects seem to be good
+%   \item user interface uses \packagename{keyval} package
+%   \item \packagename{fancyvrb} support
+% \item[0.20] from 1999/07/12
+%   \item new keyword detection mechanism
+%   \item new aspects: \aspectname{writefile}, \aspectname{breaklines},
+%         captions, \aspectname{html}
+%\iffalse
+%   \item improved \packagename{fancyvrb} support
+%\fi
+%   \item all aspects reside in a single file and the language drivers in
+%         currently two files
+% \item[0.21] 2000/08/23
+%   \item completely new User's guide
+%   \item experimental format definitions
+%   \item keyword classes replaced by families
+%   \item dynamic modes
+% \item[1.0$\beta$] 2001/09/21
+%   \item key names synchronized with \packagename{fancyvrb}
+%   \item \aspectname{frames} aspect extended
+%   \item new output concept (delaying and merging)
+% \item[1.0] 2002/04/01
+%   \item update of all documentation sections including Developer's guide

+% comment in Lisp} for the `single comment' delimiters. The keywords are the
+% `one-word' functions and macros of Common Lisp, i.e.~words not containing a
+% minus. But I left out the \texttt{caaaar}, \ldots{} functions.
+% If anyone types them in, I'd like to get them.

+%               \textbf{OMG Unified Modeling Language Specification};
+%               {\copyright} 1999 OMG;

+%    \end{macrocode}
+% First we define are very decorative style. In the OMG standard only the
+% boolean (infix (?)) operations are highlighted, but I think all OCL-defined
+% operations should be highlighted, because they are \emph{guaranteed} to be
+% side-effect-free (in OCL only side effect free evaluations or path
+% expressions are allowed).
+%    \begin{macrocode}
+\lst@definelanguage[decorative]{OCL}[OMG]{OCL}

+%    \end{macrocode} 
+% Remark: "isQuery" is not real OCL, but a important attribute of the
+% underlying UML model.
+%
+% The dialect called \texttt{OMG} is a very spare version. If you use
+% this variant with bold style for first and second order keywords you
+% get the look and feel of the OMG standard. First order keywords are the
+% OCL context declarations (see section 7.3 of the OMG standard):
+%    \begin{macrocode}
+\lst@definelanguage[OMG]{OCL}%
+    {morekeywords={context,pre,inv,post},%
+%    \end{macrocode} 
+% Second order keywords are the operation which are defined for type
+% Boolean (see pages 7-34/35 of the OMG standard) and the let-operation
+% (in principle these are the infix operations):
+%    \begin{macrocode}
+    ndkeywords={or,xor,and,not,implies,if,then,else,endif},%
+%    \end{macrocode} 
+% Third order keywords are the basic data types as declared in section 7.4 of
+% the OMG standard:
+%    \begin{macrocode}
+    morekeywords=[3]{Boolean,Integer,Real,String,Set,Sequence,Bag,%
+       OclType,OclAny,OclExpression,Enumeration,Collection,},%

+% \lstthanks{Christian~Kaiser}{chk@combit.net}{2003/02/05} provided the initial
+% definition. \lstthanks{Xavier~Noria}{fxn@hashref.com}{2004/01/11} replaced
+% the keywords with the keywords from the at the time of writing current
+% stable Ruby version.  An erroneous string delimiter was removed following
+% a bug reported on comp.text.tex on 2006/09/01.
+%
+% Ruby supports string delimiters of the form \verb|%q!...!|, where \verb|!|
+% can be any character, or can be matched braces or parentheses or brackets.
+% The included string definitions include most of the common variants, but are
+% of course not comprehensive.
