%\section{Introduction}
%\label{sec:intro}
%
% This is the ``official'' \LaTeX{} style for \emph{No Starch Press,}
% \url{http://www.nostarch.com}.  The class is intended to typeset
% books for this publisher---both hard copies and electronic books.
%
% The suite provides main class, |nostarch.cls|, hyperref interface
% |nshyper.sty| and MakeIndex style |nostarch.ist|.
%
% The initial version of this class was written in 2008.  Since then a
% number of changes was made for in-house processing by the \emph{No
% Starch} team, with special thanks to Alex Freed.  In 2023 these
% changes were incorporated back to the publicly released version. 
%
%\section{User's Guide}
%\label{sec:manual}
%
%
%\subsection{Installation}
%\label{sec:installation}
%
% The installation of the class follows the usual
% practice~\cite{TeXFAQ} for \LaTeX{} packages:
% \begin{enumerate}
% \item Run \progname{latex} on |nostarch.ins|.  This will produce the
% following files:
% \LaTeX{} class |nostarch.cls|, \LaTeX{} style |nshyper.sty| and
% MakeIndex style |nostarch.ist|.
% \item Put the files |nostarch.cls|, |nshypher.sty| and
% |nostarch.ist| to
% the places where \LaTeX{} and MakeIndex can find them (see
% \cite{TeXFAQ} or the documentation for your \TeX{}
% system).\label{item:install} 
% \item Update the database of file names.  Again, see \cite{TeXFAQ}
% or the documentation for your \TeX{} system for the system-specific
% details.\label{item:update}
% \item The file |nostarch.pdf| provides the documentation for the
% package (this is the file you are probably reading now).
% \end{enumerate}
% As an alternative to items~\ref{item:install} and~\ref{item:update}
% you can just put the files in the working directory where your
% |.tex| file is.
% 
% To typeset the books in the distinctive \emph{No Starch Press} style
% you will need the fonts used by them.  Unfortunately these fonts
% (New Baskerville, Futura, The Sans Mono Condensed and Dogma) are not
% free.  You have the following options:
% \begin{enumerate}
% \item Typeset your book using only free fonts (the option |nocfonts|
% discussed below).
% \item Buy the fonts and install them.
% \item Arrange with \emph{No Starch Press} for the use of these fonts
% for your book.
% \end{enumerate}
% The details of the installation are discussed below in
% Section~\ref{sec:ug_fonts}. 
%
%
%
%\subsection{Fonts installation}
%\label{sec:ug_fonts}
%
% If you wish to try \progname{nostarch} class without bothering to
% typeset camera-ready copy, you may use the option |nocfonts| for
% \emph{no commercial fonts,} and the class will use only the free
% fonts available in \TeX\ distributions.
%
% If you work with \emph{No Starch Press} on your book, you might be
% provided with the fonts.  Today \emph{No Starch Press} typically
% uses \progname{xelatex} and expects the fonts in True~Type format.
% If this is the case, use the option |cfonts|.  \emph{No Starch
% Press} recommends the authors to put the font files in the
% subdirectory \path{fonts} of their main directory.  This is where
% \progname{nostarch} expects them.  This is also the layout of
% directories in the \emph{No Starch Press} \emph{Overleaf}
% templates.  However, if you prefer to put the fonts in another
% directory, searcheable by \progname{xelatex}, use the option
% |nofontsdir| in the invocation.
%
% These options are summarized in Figure~\ref{fig:fonts}.
%
% \begin{figure}
%   \centering
%   \begin{tikzpicture}
%     \node[draw, circle, radius=0.1] (start) {};
%     \node[draw, align=center, below=of start]
%     (haveFonts) {Do you have \\commercial fonts?};
%     \node[draw, left=of haveFonts, align=center] (nocfonts)
%     {Use |nocfonts|\\ option};
%     \node[draw, below=of nocfonts, rounded corners]
%     (any) {Use any engine};
%     \node[draw, right=of haveFonts, align=center] (cfonts)
%     {Use |cfonts|\\option};
%     \node[draw, below=of cfonts, align=center] (haveSubdir) {Are the fonts
%     \\in |fonts| \\subdirectory?};
%     \node[draw, left=of haveSubdir, align=center]
%     (nofontsdir) {Use |nofontsdir|\\option};
%     \node[draw, below=of haveSubdir, align=center] (fontsdir)
%     {Use |fontsdir|\\option};
%     \node[draw, below=of fontsdir, rounded corners] (xelatex)
%     {Use \progname{xelatex} engine};
%     \draw[-latex] (start) -- (haveFonts);
%     \draw[-latex] (haveFonts) -- node[above] {No} (nocfonts);
%     \draw[-latex] (haveFonts) -- node[above] {Yes} (cfonts);
%     \draw[-latex] (nocfonts) --  (any);
%     \draw[-latex] (cfonts) --  (haveSubdir);
%     \draw[-latex] (haveSubdir) -- node[above] {No} (nofontsdir);
%     \draw[-latex] (haveSubdir) -- node[right] {Yes} (fontsdir);
%     \draw[-latex] (nofontsdir) |- (xelatex);
%     \draw[-latex] (fontsdir) -- (xelatex);
%   \end{tikzpicture}
%   \caption{Flowchart for font-related options}
%   \label{fig:fonts}
% \end{figure}
%
%
%\subsection{Invocation}
%\label{sec:invocation}
%
% To use the class, put in the preamble of your document
% \begin{flushleft}
% |\documentclass[|\meta{options}|]{nostarch}|
% \end{flushleft}
%
% \DescribeOptions{cfonts,nocfonts}%
% As discussed above, \emph{No  Starch Press} uses a number of
% commercial fonts to typeset their  books.  
% The option |cfonts| (default) tells \LaTeX{} that you do have these
% commercial fonts.  On the other hand, the option |nocfonts| instructs
% \LaTeX{} 
% to use freely available fonts for typesetting.  Of course in this
% case the result will not look like a \emph{No Starch Press} Book.
%
% \DescribeOptions{fontsdir,nofontsdir}%
% If you use commercial fonts \emph{and} \progname{xelatex}, the
% latter usually expects them in the subdirectory \path{fonts} of the
% main directory (see Section~\ref{sec:ug_fonts}).  The options
% |fontsdir| (default) sets up this behavior.  Use the option
% |nofontsdir| to tell \progname{xelatex} to search standard font
% directories insted.
%
% Figure~\ref{fig:fonts} may help to choose the right options.  
%
% 
%\subsection{Use of \progname{hyperref} Package}
%\label{sec:guide:hyperref}
%
% The books typeset by \emph{No Starch Press} can be sold either as
% traditional printed and bound hard copies, or as PDF files.  If you,
% the author, envisage the second possibility, you may want additional
% possibilites provided by \progname{hyperref}
% package~\cite{Rahtz06:Hyperref}, like ``clickable'' entries in the
% table of context and index, etc.  The provided package |nshyper.sty|
% adds the functionality of \progname{hyperref} to the class.  This
% package is highly recommended for the books that are going to be
% distributed in an electronic form.
%
% To use the package, just add the line |\uspackage{nshyper}| to your
% preamble.  This package should be loaded last since it redefines
% internals of many other packages.  Note that a direct call of
% \progname{hyperref} by |\usepackage{hyperref}| will not work since
% \progname{nshyper} patches hyperref to work with our class.
% 
% 
%
%\subsection{Front Matter}
%\label{sec:guide:frontmatter}
%
% \DescribeMacro{\frontmatter}
% A book can be divided into three parts:  front matter, main matter
% and back matter.  Front matter starts with the command
% |\frontmatter|.  Normally this is the first command in the class.
% Front matter contains half page, title page, copyright page, brief
% contents, detailed contents, foreword(s) and other stuff which is
% traditionally typeset on roman-numbered pages.  The commands in main
% matter can be divides into \emph{declarations} and
% \emph{directives.}  Declarations do not typeset anything.  Rather,
% they up parameters for the typesetting.  Directives use them to
% typeset the stuff.
%
%
%\subsubsection{Front Matter Declarations}
%\label{sec:guide:decls}
%
%
%
% \DescribeMacro{\title} 
% There are five declarations defined by |nostarch.cls|: |\title|,
% |\subtitle|, 
% |\author|, |\nostarchlogo| and |\nostarchlocation|.  The macro
% |\title|, like the standard \LaTeX{} |\title|, sets the title of the
% book, for example |\title|\texttt{\{The book about everything\}}.
%
% \DescribeMacro{\subtitle}
% The macro |\subtitle| takes one argument and sets up the subtitle of
% your book, for example |\subtitle|\texttt{\{A Guide For
% Perplexed\}}. 
%
% \DescribeMacro{\author}
% The command |\author| has just one argument, which is the list of
% authors, separated by commas and (for the last author) the word
% ``and''.  Do not use the command |\and| defined in the standard
% \LaTeX.  For example,
% |\author|\texttt{\{Ralph Alpher, Hans Bethe and George Gamow\}}.
% 
% \DescribeMacro{\nostarchlogo} 
% Due to copyright reasons the logo of \emph{No Starch Press} is not
% distribuded with the package.  You should get the logo as a graphics
% file from the publishers and put in the directory where \LaTeX{} can
% find it (for example, the directory with the other sources of your
% book).  The command |\nostarchlogo| has one argument: the name of
% the file, for example, |\nostarchlogo{biglogo.pdf}|.
% The file will be automatically scaled to the proper size.
%
% \DescribeMacro{\nostarchlocation}
% \emph{No Starch Press} books are usually published in San
% Francisco.  If you need to change this setting, use
% |\nostarchlocation| declaration, for example,
% |\nostarchlocation|\texttt{\{San Francisco;  London; Tokyo\}}.
% 
%
%
%\subsubsection{Front Matter Directives}
%\label{sec:guide:directives}
%
%
%
% \DescribeMacro{\makehalftitle}
% The command |\makehalftitle| creates \emph{half title page.}
% This is normally the first page of the book.
%
% \DescribeMacro{\maketitle}
% The command |\maketitle| creates \emph{title page.}  It uses logo
% and full title of the book.
%
% \DescribeMacro{copyrightpage} 
% The copyright page is the \emph{verso} of the title page.  It has
% information about copyright, edition history, the credits of the
% people who helped you to make the book, CIP information, etc.  The
% exact contents of the copyright page differ from book to book.
% Therefore the class does not try to create this page automatically,
% and rather sets up the typographic style for arbitrary contents.
% For this purpose the environment |copyrigthtpage| is used.  So just
% put the information provided by the publisher between
% |\begin{copyrightpage}| and |\end{copyrightpage}|.  Use
% |\textbf{\sffamily title}| for the title of the book on the
% copyright line.
%
% \DescribeMacro{cipblock}
% One of important parts of the copyright page is \emph{CIP block.}
% It contains catalogue data for your book (CIP means Cataloguing in
% Publication, by the way).  Again, the contents of this field will be
% provied by the publishers;  you just need to put them inside
% |cipblock| environment, i.e. between |\begin{cipblock}| and
% |\end{cipblock}|.  To make your life easier, this block is typeset
% verbatim, so line ends and spaces are typeset as is.
%
%
% \DescribeMacro{dedicationpage}
% Dedications, if any, are included in the special dedication page,
% for which a special environment |dedicationpage| is provided.  
%
% \DescribeMacro{\brieftableofcontents}
% \DescribeMacro{\tableofcontents}
% The standard \LaTeX{} provides just one table of contents.  This
% class uses two tables:  brief contents and contents in detail.  They
% are correspondingly typeset by the commands |\brieftableofcontents|
% and |\tableofcontents|. 
% 
%
% \DescribeMacro{\sectionnumberwidth}
% \DescribeMacro{\subsectionnumberwidth}
% In most books by \emph{No Starch Press} sections and subsections are
% unnumbered.  However, sometimes the books use numbered sections or
% subsections.  In these cases you may want to adjust the widths left
% for section and subsection numbers in the detailed table of
% contents.  They are set by
% |\sectionnumberwidth| and |\subsectionnumberwidth|, and can be
% changed with the usual |\setlength| command.
%
%
% Forewords and similar front matter materials are unnumbered
% chapters: |\chapter*[Foreword by R. E.~Viewer]{Foreword}|.
% 
%
% Front matter with its formal parts like copyright page, CIP
% information, etc., can be daunting, especially for novice authors.
% Feel free to use the sample enclosed and ask the publisher for
% advice. 
%
%\subsection{Main Matter}
%\label{sec:guide:mainmatter}
%
% \DescribeMacro{\mainmatter}
% The command |\mainmatter| finishes the front matter and starts the
% main matter of the book.  The main matter is divided into chapters,
% sections, subsections, etc.  They are discussed below.
%
%
%\subsubsection{Parts, Chapters and Sections}
%\label{sec:guide:sections}
%
% \DescribeMacro{\chapter}
% \DescribeMacro{\section}
% \DescribeMacro{\subsection}
% \DescribeMacro{\subsubsection}
% \emph{No Starch Press} books have chapters, sections, subsections and
% subsubsections.  The chapters are usually numbered, but sections ande
% below are not.  The commands for them are the same as in the
% standard \LaTeX: |\chapter|\oarg{short title}\marg{long title},
% |\section|\oarg{short title}\marg{long title}, etc. For
% example:
% \begin{verbatim}
% \section[Building Lego Fire Track]{How To Build A Lego Fire Track 
%    And Why It Is Fun}
% \end{verbatim}
% The ``starred'' forms |\chapter*|, |\section*| etc. are used when
% the corresponding division has no number (like unnumbered chapters in
% the front matter).  Since our sections, subsections and
% subsusbsections are unnumbered anyway, this form has meaning only
% for chapters (but can be used for other divisions as well).
%
% \DescribeMacro{\chapterart}
% \DescribeMacro{\chapterartfile}
% \emph{No Starch Press} books use  ``circular art'' for chapter
% openings (except for unnumbered chapters in the front matter).  The
% command |\chapterart| should be issued immediately 
% after |\chapter| command and before the first paragraph.  Its
% argument is the artwork used for the current chapter:
% |\chapterart|\marg{\LaTeX{} commands}.  In the
% simplest case it is just inclusion of an external graphics file, for
% example: 
% \begin{verbatim}
% \chapterart{\includegraphics[width=1.264in]{firetrack.jpg}}
% \end{verbatim}
% Actually, this simplest case is so ubiquitous, that there is a
% special command |\chapterartfile|\marg{filename} for it, so the
% previous example can be simplified as
% \begin{verbatim}
% \chapterartfile{firetrack.jpg}
% \end{verbatim}
% However, you can use instead any \LaTeX{} commands  to produce
% the artwork.  Rememer that it must be $1.264''\times1.222''$.
%
% The first paragraph after chapter start is typeset in larger size
% font than the body font.  If this paragraph is too long, you may
% need to manually change the font size back in the middle of it.  The
% simplest way to do this is the combination
% |\par\noindent\normalfont| in a strategic place.
%
%
% \DescribeMacro{\part}
% Sometimes larger books are separated into parts.  The command
% |\part|\marg{Title} is used to typeset parts.
%
%\subsubsection{Environments}
%\label{sec:guide:lists}
%
%
% \DescribeMacro{itemize}
% \DescribeMacro{enumerate}
% \DescribeMacro{description}
% \DescribeMacro{aside}
% \DescribeMacro{note}
% \DescribeMacro{warning}
% The class offers standard |itemize|, |enumerate| and |description|
% environment. There are also special environments reserverd for
% asides. The |aside| environment has a mandatory argument: aside
% name.  It typesets its contents in italics with the name in bold on
% the marginh:
% \begin{verbatim}
% \begin{aside}{Reminder}
%   Do not forget to plug off the computer before doing any
%   modifications! 
% \end{aside}
% \end{verbatim}
% The environments |note| and |warning| are similar, but have
% pre-defined names NOTE and WARNING, e.g
% \begin{verbatim}
% \begin{note}
%   Do not forget to plug off the computer before doing any
%   modifications! 
% \end{note}
% \begin{warning}
%   Do not forget to plug off the computer before doing any
%   modifications! 
% \end{warning}
% \end{verbatim}
%
%
%\subsubsection{Tables and Figures}
%\label{sec:guide:floats}
%
% There are several things to keep in mind when using tables and
% figures with the class.
%
% The tables and figures are not centered.  Neither are their
% captions. The captions for figures go \emph{below} the figures, the
% captions for tables go \emph{above} the tabular data.  
%
% \DescribeMacro{\NextCaptionWidth}%
% The captions of tables and figures are automatically typeset with
% the same width as the table or figure.  Sometimes, however, \LaTeX\
% makes a mistake in the calculation.  In this case the macro
% \cs{NextCaptionWidth}\marg{length} overrides this calculation and
% sets the width of the caption for the next figure or table to
% \marg{length}, for example
% \begin{verbatim}
% \NextCaptionWidth{2in}
% \begin{figure}
%   ...
%   \caption{...}
% \end{figure}
% \end{verbatim}
%
% 
% Typesetting tables, unfortunately, is rarely done right, and
% standard \LaTeX{} is not an exception.  The authors are urged to
% read the introduction to \progname{booktabs}
% package~\cite{Fear05:Booktabs}.  To summarize,
% \begin{enumerate}
% \item Never ever use vertical rules.
% \item Never ever use double rules.
% \item Use only |\toprule|, |\midrule| and |\bottomrule| for tables. 
% \end{enumerate}
% \DescribeMacro{\tbfont}
% \DescribeMacro{\thfont}
% \DescribeMacro{tabular}
% \emph{No Starch Press} uses special fonts for table body and table
% header.  Since there are too many tabular-like environments
% (|tabular|, |tabbing|, |longtable|, \dots) we do not redefine them
% switch on these fonts automatically, but rather provide two font
% switching commands.  The command |\tbfont| should be used
% \emph{before} tabular environment, and the command |\thfont| should
% be used in all header cells.  Also, usually the table entries are
% flushed left, so you might want to put |@{}| before the first column
% declaration in |\begin{tabular}| to suppress the padding on the
% left. Here is an example of a properly
% done table layout:
% \begin{verbatim}
% \begin{table}
%   \caption{Starch Content of Foods}
%   \label{tab:starch}
%   \tbfont
%   \begin{tabular}{@{}lr}
%     \toprule
%      \thfont Product        & \thfont Starch Content, \% \\ 
%     \midrule
%      Bran (wheat)           & 23.0\\
%      Brown rice (raw)       & 80.0\\
%      Brown bread (average)  & 41.3\\
%      White bread (average)  & 46.7\\
%     \bottomrule
%   \end{tabular}
% \end{table}
% \end{verbatim}
% 
%
%
%\subsubsection{Code Fragments}
%\label{sec:guide:code}
%
% The class provides two facilities for including code fragments in
% the books.  
%
% \DescribeMacro{Code}
% For short unformatted code fragments the  \progname{fancyvrb}
% package~\cite{VanZandt98:Fancyvrb} facilities are recommended.  This
% package is automatically automatically loaded by the class.  Long code
% fragments should be 
% separated by rules;  the class defines verbatim-like |Code|
% environment, which does exactly this:
% \begin{verbatim}
% \begin{Code}
%   main() {
%        printf("Hello, World\n");
%   }
% \end{Code}
% \end{verbatim}
% See the documentation of~\cite{VanZandt98:Fancyvrb} about many
% features of this package.
%
% For longer code fragments the \progname{listings}
% package~\cite{Heinz07:Listings} is more appropriate.  It is also
% automatically loaded.  This package provides a number of useful
% features, well describe in its manual.  We will briefly mention
% several of them, which might be of interest for the authors of
% \emph{No Starch Press}:
% \begin{enumerate}
% \item Automatic code formatting according to the rules of the chosen
% program language (for example, |\lstset{language=C}| or
% |\lstset{language=Lisp}|).
% \item A rich set of different frames:  ruled code with
% |frame=lines|, boxed code with |frame=single| etc.
% \item An option to add captions to the listings (the class
% automatically formats the captions according to the style of
% \emph{No Starch Press}).
% \item An option to make a listing floating.
% \item An option to automatically number code lines.
% \item An option to add list of listings (with the command
% |\lstlistoflistings|). 
% \end{enumerate}
% 
% To make the code in |\verb| commands and |verbatim|-like
% environments be typeset with the \progname{listings} package, you
% may want to  set |fancyvrb=true| in the preamble of your document.
%
% It should be noted that the authors are recommended \emph{not} to
% use |\texttt| or |\tt| for inline code fragments.  The proper way to
% add inline code is |\verb| or |\lstinline| from the
% \progname{listings} package.  The difference is obvious, for
% example, in quote characters.
%
%
%\subsection{Boxes}
%\label{sec:ug_boxes}
%
% \DescribeEnv{nspbox}%
% You may put some information into \emph{boxes}.  Boxes have a \emph{heading}
% and a \emph{text}.  The environment |nspbox| can be used to typeset
% them, for example:
% \begin{verbatim}
% \begin{nspbox}{This is a heading}
%   This is a text for the box.  
% \end{nspbox}
% \end{verbatim}

%\subsection{Back Matter}
%\label{sec:guide:backmatter}
%  
% \DescribeMacro{\backmatter}
%  Back matter includes bibliography, index, update page, colophon and
%  other material.  It starts with the command |\backmatter|.
%
%
%
%\subsubsection{Bibliography}
%\label{sec:guide:bibliography}
% 
% \emph{No Starch Press} at present has no special style for
% bibliography, so the authors have a relative freedom to choose one.
% However, it would be a good idea to use the \progname{natbib}
% package~\cite{Daly07:Natbib}.  This class should work with
% \progname{natbib}.
%
% No support for per chapter bibliography lists is provided by the
% package. 
%
%
%\subsubsection{Index}
%\label{sec:guide:index}
%
% The books published by \emph{No Starch Press} usually have index.
% This package provides special style file |nostarch.ist| for index
% formatting.
%
%
% \DescribeMacro{\makeindex} 
% \DescribeMacro{\printindex} 
% To create index:
% \begin{enumerate}
%
% \item Put in the preamble of your
% document the command |\makeindex|. 
% \item In the body of your document use |\index| commands as
% described in~\cite{Lamport94}.
% \item Put in the Back Matter the command |\printindex| at the place
% you want the index to be printed.
% \item After a \progname{latex} run \progname{makeindex} with the
% style |nostarch.ist|.  In a Unix system the corresponding command is
% \begin{verbatim}
% makeindex -s nostarch.ist mydocument
% \end{verbatim}
% or, in a more verbose way
% \begin{verbatim}
% makeindex -s nostarch.ist -o mydocument.ind mydocument.idx
% \end{verbatim}
% (here we assume that your main file is |mydocument.tex|).  
%
% Refer to the documentation of your \TeX{} system for the way to run
% \progname{makeindex} on your computer.
% \end{enumerate}
% 
%
%\subsubsection{Updates and Colophon}
%\label{sec:guide:updates}
%
% \DescribeMacro{\updatespage}
% \emph{No Starch Press} books usually have updates page, which lists
% the Web address for updates, errata, etc.  The command
% |\updatespage| starts such page.  You are free to choose any text
% there.  Note that if you use the package
% \progname{nshypher}~\ref{sec:guide:hyperref}, then the command
% |\url|\marg{URL} becomes a hyperlink in the electronic edition.
%
%
% \DescribeMacro{\colophon}
% The last part of Back Matter is usually a \emph{colophon} which
% describes how the book was printed and typeset.  The command
% |\colophon| starts this part and prints some standard information
% about your fonts and \LaTeX{} package.  You may want to add some
% information after this command.

%\subsection{Dealing with \progname{hyperref}}
%\label{sec:hyperref}
%
% \changes{v0.6}{2008/03/22}{Introduced package \progname{nshyper}} 
% First, we load \progname{hyperref} with right options.  I do not
% know why bookmarks do not work, but this is important to switch off:
%    \begin{macrocode}
%<*nshyper>
\RequirePackage[breaklinks,colorlinks,linkcolor=black,
  citecolor=black,pagecolor=black,urlcolor=black,hyperindex]{hyperref}
%    \end{macrocode}
% 
% \progname{hyperref} expects the starred parts and chapters to have
% only one argument---but we have two!
%    \begin{macrocode}
\AtBeginDocument{%
  \def\@schapter[#1]#2{%
    \H@old@schapter[#1]{#2}%
  \@nschapterpreamble}%
  \def\@spart[#1]#2{%
    \H@old@spart[#1]{#2}%
    \Hy@GlobalStepCount\Hy@linkcounter
    \xdef\@currentHref{part*.\the\Hy@linkcounter}%
    \Hy@raisedlink{\hyper@anchorstart{\@currentHref}\hyper@anchorend}}}%
%    \end{macrocode}
% We change the preamble for bibliography and index:
%    \begin{macrocode}
\def\@nschapterpreamble{%
  \begingroup
  \let\@mkboth\@gobbletwo
  \Hy@GlobalStepCount\Hy@linkcounter
  \xdef\@currentHref{\Hy@chapapp*.\the\Hy@linkcounter}%
  \Hy@raisedlink{\hyper@anchorstart{\@currentHref}\hyper@anchorend}%
  \endgroup}
%    \end{macrocode}
% 
% We can add information about the file to the pdf metadata as well:
%    \begin{macrocode}
\let\ns@old@maketitle\maketitle
\def\maketitle{%
  \hypersetup{pdfauthor=\@author, pdftitle=\@title}%
  \ns@old@maketitle}
%</nshyper>

%\subsection{\progname{MakeIndex} Style File}
%\label{sec:makeindex}
% \changes{v0.6}{2008/03/23}{Added \progname{MakeIndex} style} 
%
% These lines will produce some warnings when
% running Makeindex as they try to cover two different
% versions of the program:
%    \begin{macrocode}
%<*ist>
lethead_prefix   "\\indexgroup{"
lethead_suffix   "}\\nopagebreak\n"
lethead_flag       1
