-% \subsection{Introduction}
-% \hologo{LaTeX} counters can be represented in different ways
-% by using presentation commands:
-% \begin{quote}
-%   \cs{arabic}, \cs{roman}, \cs{Roman},\\
-%   \cs{alph}, \cs{Alph}, \cs{fnsymbol}
-% \end{quote}
-% The ranges of supported counter values are more or less
-% restricted. Only \cs{arabic} can be used with any counter
-% value \hologo{TeX} supports.
-% \begin{quote}
-% \catcode`\|=12 %
-% \begin{tabular}{@{}l|l|l|l@{}}
-% Presentation & Supported & Ignored & Error message\\
-% command      & domain    & values  & ``Counter too large''\\
-% \hline
-% \cs{arabic}
-%   & \ttfamily -MAX..MAX & &\\
-% \cs{roman}, \cs{Roman}
-%   & \ttfamily 1..MAX & \ttfamily -MAX..0 &\\
-% \cs{alph}, \cs{Alph}
-%   & \ttfamily 1..26 & 0 & \ttfamily -MAX..-1, 27..MAX\\
-% \cs{fnsymbol}
-%   & \ttfamily 1..9 & 0 & \ttfamily -MAX..-1, 10..MAX\\
-% \hline
-% \end{tabular}\\[1ex]
-% \texttt{MAX} = \texttt{2147483647}
-% \end{quote}
-% Ordinal numbers are often used in documents: numbering
-% of chapters, sections, figures, footnotes and so on.
-% The layouter chooses \cs{Alph} for chapter numbers
-% and \cs{fnsymbol} for footnotes. But what can be done
-% if there are more than 26 chapters or more than 10 footnotes?
-% This package \xpackage{alphalph} allows to define new
-% presentation commands. They rely on a existing command
-% and define presentations for values greater the limits.
-% Three different methods are provided by the package.
-% In the following use cases they are presentated.
-%
-% \subsection{Use cases}
-%
-% \subsubsection{Number system based on symbols}
-%
-% Asume you are writing a book and your lecturer demands
-% that chapter numbers must be letters. But you have already
-% 30 chapters and you have only 26 letters?
-%
-% In the decimal system the situation would be clear.
-% If you run out of digits, you are using more digits
-% to represent a number. This method can be also be used
-% for letters. After chapter 26 with |Z| we us |AA|, |AB|, |AC|, and |AD|
-% for the remaining chapters.
-%
-% Happily this package already defines this presentation command:
-%\begin{quote}
-%\begin{verbatim}
-%\usepackage{alphalph}
-%\renewcommand*{\thechapter}{%
-%  \AlphAlph{\value{chapter}}%
-%}
-%\end{verbatim}
-%\end{quote}
-% \cs{AlphAlph} generates:
-%   \AlphAlph{1}, \AlphAlph{2}, \AlphAlph{3}, \dots,
-%   \AlphAlph{26}, \AlphAlph{27}, \AlphAlph{28}, \dots
-%
-% The other presentation command is \cs{alphalph} for lowercase letters.
-%
-% \subsubsection{Wrap symbols around}
-%
-% Nine footnote symbols are quite a few.
-% Too soon the symbols are consumed
-% and \hologo{LaTeX} complains with the error ``Counter too large''.
-% However, it could be acceptable to start again with the symbols
-% from the beginning, especially if there are less than nine symbols
-% on a page.
-% This could be achieved by a counter reset.
-% But finding the right place can be difficult or needs manual
-% actions. Also a
-% unique counter value can be desirable (e.g. for generating
-% unique anchor/link names).
-% Package \xpackage{alphalph} allows you to define
-% a macro that implements a ``wrap around'', but letting
-% the value of the counter untouched:
-%\begin{quote}
-%\begin{verbatim}
-%\usepackage{alphalph}
-%\makeatletter
-%\newalphalph{\fnsymbolwrap}[wrap]{\@fnsymbol}{}
-%\makeatother
-%\renewcommand*{\thefootnote}{%
-%  \fnsymbolwrap{\value{footnote}}%
-%}
-%\end{verbatim}
-%\end{quote}
-% \cs{fnsymbolwrap} generates:
-% \fnsymbolwrap{1}~(1), \fnsymbolwrap{2}~(2), \fnsymbolwrap{3}~(3), \dots,
-% \fnsymbolwrap{9}~(9), \fnsymbolwrap{10}~(10), \fnsymbolwrap{11}~11, \dots
-%
-% \subsubsection{Multiple symbols}
-%
-% \Hologo{LaTeX}'s standard set of footnote symbols contains doubled
-% symbols at the higher positions. Could this principle
-% be generalized?
-% Yes, but first we need a clean footnote symbol list without
-% doubled entries, example:
-%\begin{quote}
-%\begin{verbatim}
-%\usepackage{alphalph}
-%\makeatletter
-%\newcommand*{\fnsymbolsingle}[1]{%
-%  \ensuremath{%
-%    \ifcase#1%
-%    \or *%
-%    \or \dagger
-%    \or \ddagger
-%    \or \mathsection
-%    \or \mathparagraph
-%    \else
-%      \@ctrerr
-%    \fi
-%  }%
-%}
-%\makeatother
-%\newalphalph{\fnsymbolmult}[mult]{\fnsymbolsingle}{}
-%\renewcommand*{\thefootnote}{%
-%  \fnsymbolmult{\value{footnote}}%
-%}
-%\end{verbatim}
-%\end{quote}
-% The own definition of \cs{fnsymbolsingle} has the
-% advantage that this list can easily modified.
-% Otherwise you can use \cs{@fnsymbol} directly,
-% because it uses the same first five symbols.
-%\begin{quote}
-%\begin{verbatim}
-%\usepackage{alphalph}
-%\makeatletter
-%\newalphalph{\fnsymbolmult}[mult]{\@fnsymbol}{5}
-%\makeatother
-%\renewcommand*{\thefootnote}{%
-%  \fnsymbolmult{\value{footnote}}%
-%}
-%\end{verbatim}
-%\end{quote}
-% \cs{fnsymbolmult} generates:
-% \fnsymbolmult{1}~(1), \fnsymbolmult{2}~(2), \fnsymbolmult{3}~(3),
-% \fnsymbolmult{4}~(4), \fnsymbolmult{5}~(5), \fnsymbolmult{6}~(6),
-% \dots, \fnsymbolmult{16}~16, \fnsymbolmult{17}~17, \dots
-%
-% \bigskip
-% The same method can also be used for the chapter problem
-% in the first discussed use case:
-%\begin{quote}
-%\begin{verbatim}
-%\usepackage{alphalph}
-%\makeatletter
-%\newalphalph{\AlphMult}[mult]{\@Alph}{26}
-%\makeatother
-%\renewcommand*{\chapter}{%
-%  \AlphMult{\value{chapter}}%
-%}
-%\end{verbatim}
-%\end{quote}
-% \cs{AlphMult} then generates AA, BB, CC, and DD for chapters 27--30.
-%
-% \subsection{Glossary}
-%
-% \begin{description}
-% \item[Counter presentation command] is a macro that
-%   expects a \hologo{LaTeX} counter name as argument.
-%   Numbers cannot be used. Examples:
-%   \cs{arabic}, \cs{alph}, \cs{fnsymbol}.
-% \item[Number presentation command] is a macro that
-%   expects a number as argument. A number is anything
-%   that \hologo{TeX} accepts as number including \cs{value}.
-%   Examples: \cs{alphalph}, \cs{AlphAlph}, \cs{alphalph@alph}
-%
-%   However, \cs{alph} or \cs{fnsymbol} are not number
-%   presentation commands because they expect a counter
-%   name as argument. Happily \hologo{LaTeX} counter presentation
-%   commands internally uses number presentation commands
-%   with the same name, but prefixed by `@'. Thus
-%   \cs{@alph}, \cs{@fnsymbol} are number presentation commands.
-% \item[Symbols provider] is a command that can be used
-%   to get a list of symbols. For example, \cs{@Alph}
-%   provides the 26 uppercase letters from `A' to `Z'.
-%   Basically a symbol provider is a number presentation
-%   command, usually with a limited range.
-% \item[Number of symbols] is the number of the
-%   last symbol slot of a symbol provider. Thus \cs{@Alph}
-%   generates 26 symbols, \cs{@fnsymbol} provides 9 symbols.
-% \end{description}
-%
-% \subsection{Package usage}
-%
-% The package \Package{alphalph} can be used with both \hologo{plainTeX}
-% and \hologo{LaTeX}:
-% \begin{description}
-% \item[\hologo{plainTeX}:] |\input alphalph.sty|
-% \item[\hologo{LaTeX2e}:]   |\usepackage{alphalph}|\\
-%      There aren't any options.
-% \end{description}
-%
-% \subsection{User commands}
-%
-% \begin{declcs}{AlphAlph} \M{number}\\
-%   \cs{alphalph} \M{number}
-% \end{declcs}
-% Both macros are number presentation commands that
-% expects a number as argument. \hologo{LaTeX} counters
-% are used with \cs{value}.
-%
-% The macros represents a number by letters.
-% First single letters |A..Z| are used, then
-% two letters |AA..ZZ|, three letters |AAA...ZZZ|, \dots
-% follow.
-%
-% Macro \cs{AlphAlph} uses uppercase letters,
-% \cs{alphalph} generates the lowercase variant.
-% \begin{quote}
-%   \catcode`\|=12
-%   \def\entry#1{
-%     \texttt{#1}
-%     & \texttt{\AlphAlph{#1}}
-%     & \texttt{\alphalph{#1}}
-%   }
-%   \begin{tabular}{@{}l|l|l@{}}
-%     \meta{number} & \verb|\AlphAlph{|\meta{number}\verb|}|
-%                   & \verb|\alphalph{|\meta{number}\verb|}|\\
-%     \hline
-%     \entry{1}\\
-%     \entry{2}\\
-%     \entry{26}\\
-%     \entry{27}\\
-%     \entry{30}\\
-%     \entry{2000}\\
-%     \entry{3752127}\\
-%     \entry{10786572}\\
-%     \entry{2147483647}\\
-%   \end{tabular}
-% \end{quote}
-%
-% \begin{declcs}{newalphalph}
-%   \M{cmd}
-%   |[|\meta{method}|]|
-%   \M{symbols provider}
-%   \M{number of symbols}
-% \end{declcs}
-% Macro \cs{newalphalph} defines \meta{cmd} as new
-% number presentation command. Like \cs{newcommand} an error
-% is thrown, if macro \meta{cmd} already exists.
-%
-% The \meta{method} is one of |alph|, |wrap|, or |mult|.
-% The default is |alph|.
-%
-% As symbol provider a number presentation command
-% can be used, e.g. \cs{@fnsymbol}, \cs{@Alph}, or
-% \cs{alphalph@alph}.
-%
-% The last argument is the number of symbols.
-% If the argument is empty, then \cs{newalphalph} tries
-% to find this number itself. \hologo{LaTeX}'s number presentation
-% commands throw an error message, if the number is too large.
-% This error message is put in a macro \cs{@ctrerr}.
-% Thus \cs{newalphalph} calls the symbol provider and tests
-% a number by typesetting it in a temporary box. The error
-% macro \cs{@ctrerr} is catched, it proofs that the number
-% is not supported. Also if the width of the result is zero
-% the number is considered as unavailable.
-%
-% The empty argument is useful for potentially variable lists.
-% However if the end cannot be detected, then the number of
-% symbols must be given. This is also a lot faster. Therefore don't
-% let the argument empty without reason.
-%
-% \subsection{Programmer commands}
-%
-% \begin{declcs}{alphalph@Alph} \M{number}\\
-%   \cs{alphalph@alph} \M{number}
-% \end{declcs}
-% They are basically the same as \cs{@Alph} and \cs{@alph}.
-% Some languages of package \xpackage{babel} redefine
-% \hologo{LaTeX}'s macros to include some font setup that
-% breaks expandibility. Therefore \cs{AlphAlph} and \cs{alphalph}
-% are based on \cs{alphalph@Alph} and \cs{alphalph@alph} to get
-% the letters. The behaviour of these symbol providers for numbers
-% outside the range |1..26| is undefined.
-%
-% \subsection{Design principles}
-%
-% \subsubsection{Number presentation commands}
-%
-% All number presentation commands that this package defines
-% (including \cs{alphalph} and \cs{AlphAlph}) have the following
-% properties:
-% \begin{itemize}
-% \item They are fully expandable. This means that they can safely
-%       \begin{itemize}
-%       \item be written to a file,
-%       \item used in moving arguments (\hologo{LaTeX}: they are \emph{robust}),
-%       \item used in a \cmd{\csname}-\cmd{\endcsname} pair.
-%       \end{itemize}
-% \item If the argument is zero or negative, the commands expand
-%       to nothing like \cmd{\romannumeral}.
-% \item The argument is a \hologo{TeX} number. Anything that would be
-%       accepted by \cmd{\number} is a valid argument:
-%       \begin{itemize}
-%       \item explicite constants,
-%       \item macros that expand to a number,
-%       \item count registers, \hologo{LaTeX} counter can used
-%             via \cmd{\value}, e.\,g.:\\
-%             |\alphalph{\value{page}}|
-%       \item \dots
-%       \end{itemize}
-% \item \hologo{eTeX}'s numeric expressions are supported, if \hologo{eTeX} is
-%       available. Then \cs{numexpr} is applied to the argument.
-%       Package \cs{calc}'s expressions are not supported.
-%       That would violate the expandibility.
-% \end{itemize}
-%
-% \subsubsection{General usability}
-%
-% \begin{description}
-% \item[\hologo{TeX} format:]
-%   The package does not depend on \hologo{LaTeX}, it can also be used
-%   by \hologo{plainTeX}, for example.
-% \item[\hologo{eTeX}:] \eTeX is supported, the macros are shorter and
-%   faster. But \eTeX's extensions are not requirements.
-%   Without \hologo{eTeX}, just the implementation changes. The properties
-%   remain unchanged.

-% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{alphalph}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/alphalph.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/alphalph.pdf}] Documentation.
-% \end{description}
-%
-%
-% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
-% are also available in a TDS compliant ZIP archive. There
-% the packages are already unpacked and the documentation files
-% are generated. The files and directories obey the TDS standard.
-% \begin{description}
-% \item[\CTANinstall{install/macros/latex/contrib/oberdiek.tds.zip}]
-% \end{description}
-% \emph{TDS} refers to the standard ``A Directory Structure
-% for \TeX\ Files'' (\CTANpkg{tds}). Directories
-% with \xfile{texmf} in their name are usually organized this way.
-%
-% \subsection{Bundle installation}
-%
-% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
-% TDS tree (also known as \xfile{texmf} tree) of your choice.
-% Example (linux):
-% \begin{quote}
-%   |unzip oberdiek.tds.zip -d ~/texmf|
-% \end{quote}
-%
-% \subsection{Package installation}
-%
-% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
-% \docstrip\ archive. The files are extracted by running the
-% \xfile{.dtx} through \plainTeX:
-% \begin{quote}
-%   \verb|tex alphalph.dtx|
-% \end{quote}
-%
-% \paragraph{TDS.} Now the different files must be moved into
-% the different directories in your installation TDS tree
-% (also known as \xfile{texmf} tree):

-% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
-% TDS installing feature, then some files can already be in the right
-% place, see the documentation of \docstrip.
-%
-% \subsection{Refresh file name databases}
-%
-% If your \TeX~distribution
-% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
-% these. For example, \TeX\,Live\ users run \verb|texhash| or
-% \verb|mktexlsr|.
-%
-% \subsection{Some details for the interested}
-%
-% \paragraph{Unpacking with \LaTeX.}
-% The \xfile{.dtx} chooses its action depending on the format:
-% \begin{description}
-% \item[\plainTeX:] Run \docstrip\ and extract the files.
-% \item[\LaTeX:] Generate the documentation.
-% \end{description}
-% If you insist on using \LaTeX\ for \docstrip\ (really,
-% \docstrip\ does not need \LaTeX), then inform the autodetect routine
-% about your intention:
-% \begin{quote}
-%   \verb|latex \let\install=y\input{alphalph.dtx}|
-% \end{quote}
-% Do not forget to quote the argument according to the demands
-% of your shell.
-%
-% \paragraph{Generating the documentation.}
-% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
-% the documentation. The process can be configured by the
-% configuration file \xfile{ltxdoc.cfg}. For instance, put this
-% line into this file, if you want to have A4 as paper format:
-% \begin{quote}
-%   \verb|\PassOptionsToClass{a4paper}{article}|
-% \end{quote}
-% An example follows how to generate the
-% documentation with pdf\LaTeX:
-% \begin{quote}
-%\begin{verbatim}
-%pdflatex alphalph.dtx
-%makeindex -s gind.ist alphalph.idx
-%pdflatex alphalph.dtx
-%makeindex -s gind.ist alphalph.idx
-%pdflatex alphalph.dtx

-% This package replaces \cs{includeonly} by an interactive user
-% interface.
-% \end{abstract}
-%
-% \tableofcontents
-%
-% \section{Documentation}
-%
-% \subsection{User interface}
-%
-% The \cs{include} feature of \LaTeX\ allows the division of
-% the text body in separate compilation units. It is page
-% based and stores counter settings in additional auxiliary
-% files. \cs{includeonly} limits the actually included files
-% to the ones, listed in its argument.
-%
-% Example:
-%\begin{quote}
-%\begin{verbatim}
-%\documentclass{report}
-%
-%\usepackage{askinclude}
-%
-% % Don't use \include in the preamble.
-% % Instead \input can be used or make a package
-%
-%\begin{document}
-%\include{title}
-%\include{introduction}
-%\include{summary}
-%\include{index}
-%\end{document}
-%\end{verbatim}
-%\end{quote}
-%
-% Package \xpackage{askinclude} adds an interactive user interface.
-% The user is asked which files he want to include and sets
-% \cs{includeonly} accordingly.
-%
-% The first time the package is used the question looks like:
-%\begin{quote}
-%\begin{verbatim}
-%***********************************
-%*** Package askinclude Question ***
-%***********************************
-%
-%Previous answer (noregexp):
-%     [*]
-%
-%Regular expressions:
-% --> [noregexp]  disabled
-%     [makematch] enabled, using package `makematch'
-%     [pdfmatch]  enabled, using pdfTeX's \pdfmatch
-%
-%Which files do you want to include?
-%     [foo,bar]   comma separated file or pattern list
-%     [*]         all files
-%     [-]         no files
-%     [?]         ask for each file
-%     []          use the previous answer
-%
-%\answer=chapter2,summary
-%\end{verbatim}
-%\end{quote}
-% Square brackets are used as quotation symbols,
-% they are not part of the answer.
-% The answer by the user follows in the last line after |\answer=|.
-% \begin{description}
-% \def\Item[#1]{\item[{[\texttt{#1}]:}]}
-% \Item[foo,bar]
-%   A comma separated file list (also one file only) is passed
-%   to macro \cs{includeonly} directly. If regular expression support
-%   is enabled, the entries in the list are interpreted as
-%   file name patterns that will be matched against the file names
-%   in \cs{include}, see \hyperref[sec:regexp]{section \ref*{sec:regexp}}.
-% \Item[*] This is a shortcut for specifying \emph{all} files.
-% \Item[-] This means \emph{none} of the files is included.
-% \Item[?] The switches in single asking mode.
-%   The user will be asked at each \cs{include}.
-%   See section \hyperref[sec:single]{section \ref*{sec:single}}.
-% \Item[] Just pressing return (empty string) uses the default
-%   answer, that was stored in the auxiliary file (\xfile{.aux})
-%   of the previous \LaTeX run with package \xpackage{askinclude}.
-%   Without previous runs the default is [|*|] for all files.
-% \Item[noregexp] Turns regular expression support off.
-% \Item[makematch] Enables regular expression support
-%   package \xpackage{makematch} provides.
-% \Item[pdfmatch] It is shown, if \pdfTeX~1.30 or later is used.
-%   It relies on an undocumented feature \cs{pdfmatch} that may
-%   change in future versions of \pdfTeX.
-% \end{description}
-% Package \xpackage{askinclude} remembers the files of \cs{include}
-% in the auxiliary file and the given answer. they are
-% presented at the next run
-% at the start of the question:
-%\begin{quote}
-%\begin{verbatim}
-%***********************************
-%*** Package askinclude Question ***
-%***********************************
-%
-%Files, found by previous run in \include:
-%     (-) title
-%     (-) introduction
-%     (-) chapter1
-%     (+) chapter2
-%     (-) chapter3
-%     (+) summary
-%
-%Previous answer (noregexp):
-%     [chapter2,summary]
-%...
-%\end{verbatim}
-%\end{quote}
-% |(+)| and |(-)| marks files that were and were not included in
-% the previous run. The file list and marks are not always correct.
-% For example, if \cs{include} statements are added or removed.
-% If the method of regular expression support is different,
-% then the marks only reflects the mode of the previous answer.
-%
-% \subsection{Single asking mode}
-% \label{sec:single}
-%
-% The special answer `|?|' trigger single asking mode,
-% at the next \cs{include} the user is asked again:
-%\begin{quote}
-%\begin{verbatim}
-%***********************************
-%*** Package askinclude Question ***
-%***********************************
-%
-%Include `title'? [y]es, [n]o, [A]ll, [N]one, [D]efault (n):
-%
-%\answer=
-%\end{verbatim}
-%\end{quote}
-% Use the letter inside the square brackets as answer.
-% An empty string uses the default answer, the letter in parentheses.
-% The answers are:
-% \begin{description}
-% \def\Item[#1]{\item[{[\texttt{#1}]:}]}
-% \Item[y] The file is included.
-% \Item[n] The file is excluded.
-% \Item[A] This file and all following files are included.
-% \Item[N] This file and all following files are excluded.
-% \Item[D] Use the default answer for this and all following files.
-% \end{description}
-% If the file is known from the previous run, then the
-% default is `|y|' or `|n|' corresponding to the mark
-% `|(+)|' or `|(-)|' in the list of previous files.
-% Otherwise `|y|' is used as default.
-%
-% \subsection{Regular expressions}
-% \label{sec:regexp}
-%
-% Three methods are available that can also set by package options:
-% \begin{description}
-% \def\Item[#1]{\item[\xoption{#1}:]}
-% \Item[noregexp] Regular expression support is disabled.
-% \Item[makematch] Use package \xpackage{makematch}.
-% \Item[pdfmatch] Use \pdfTeX's \cs{pdfmatch} if available.
-% \end{description}
-% Without options the value remembered in the auxiliary file
-% is used, otherwise the default is \xoption{noregexp}.
-%
-% \subsubsection{Method \xoption{makematch}}
-%
-% Package \xpackage{makematch} (part of \xpackage{qstest}), written
-% by David Kastrup provides pattern matching based on wildcards:
-% \begin{description}
-% \item[{[\texttt{*}]}:] The star matches zero or more characters.
-% Thus a lonely star machtes anything.
-% \item[{[\texttt{!}]}:] The exclamation mark at the begin of a
-% pattern negates it, thus the matching files are excluded.
-% \end{description}
-% The pattern list is evaluated for a file name from left to
-% right. Always a file name must match the whole pattern.
-% The file is included if it is matched by a pattern and
-% not excluded afterwards. Examples:
-% \begin{quote}
-% \def\no{\textrm{$\emptyset$}}
-% \begin{tabular}{>{\ttfamily}l|>{\ttfamily}l|>{\ttfamily}l}
-% \textrm{Pattern list} & \textrm{File names} & \textrm{Result}\\
-% \hline
-% foobar & foobar,dummy & foobar\\
-% foo*  & foobar,xfoobar & foobar\\
-% \relax *foo* & xfoobar & xfoobar\\
-% f*b*r & foobar  & foobar\\
-% \relax *     & any     & any\\
-% !foobar & foobar,other & other\\
-% !foo*   & xfoobar & xfoobar\\
-% in*,!*dex & intro,index & intro\\
-% !index,in* & intro,index & intro,index\\
-% \relax *,!chap2 & chap1,chap2,chap3 & chap1,chap3\\
-% \end{tabular}
-% \end{quote}
-% The example in the last line shows, how the behaviour of package
-% \xpackage{excludeonly} \cite{excludeonly} can be simulated.
-%
-% The documentation of package \xpackage{makematch} tells the
-% the empty pattern does not match anything. But if you answer
-% the question with an empty string the answer of the previous
-% run is used. Also curly braces are not reliable because the
-% can get stripped during the processing of the answer.
-% Using a pair of empty curly braces or the comma for two empty
-% patterns currently works, but this is specific for the current
-% implementation and may change in future. But the special
-% answer `-' is available.
-%
-% \subsubsection{Method \xoption{pdfmatch}}
-%
-% In \pdfTeX\ 1.30 the new primitive \cs{pdfmatch} was introduced.
-% It is not documented yet, because it was not decided if it remains
-% and which implementation of regular expressions should be used.
-% Thus the situation may change in later versions of \pdfTeX.
-% Currently (1.30 until 1.40) it uses a library for POSIX 1003.2 regular
-% expressions, see manual page ``regex(7)''.
-%
-% If a pattern in the pattern list is invalid, the package prints
-% a warning and removes the pattern from the list. Actually there
-% are two warnings, the other warning is generated by \pdfTeX\ itself.
-%
-% In opposite to \xoption{makematch} the pattern only needs to
-% match the specified part of the file name.
-% For matching the whole name, the symbols `|^|' and `|$|' for
-% begin and end of string must be included.
-%
-% Additionally an initial exclamation mark `|!|' implements the
-% same logic as method \xoption{makematch}. The match result is
-% inverted, the matched file excluded.
-%
-% Examples:
-% \begin{quote}
-% \def\no{\textrm{$\emptyset$}}
-% \begin{tabular}{>{\ttfamily}l|>{\ttfamily}l|>{\ttfamily}l}
-% \textrm{Pattern list} & \textrm{File names} & \textrm{Result}\\
-% \hline
-% foobar & foobar,dummy & foobar\\
-% foo.*  & foobar,xfoobar & foobar,xfoobar\\
-% |^|foo.* & foobar,xfoobar & foobar\\
-% foo|$| & foo,foobar & foo\\
-% fo?bar & fbar,fobar,foobar  & fbar,fobar\\
-% fo+bar & fbar,fobar,foobar  & fobar,foobar\\
-% fo*bar & fbar,fobar,foobar & fbar,fobar,foobar\\
-% chap3 & chap3,chap32 & chap1,chap3,chap32\\
-% chap[13] & chap1,chap2,chap3 & chap1,chap3\\
-% chap(1\string|3)|$| & chap1,chap3,chap33 & chap1,chap3\\
-% .*     & any     & any\\
-% !foobar & foobar,other & other\\
-% in.*,!dex & intro,index & intro\\
-% !index,in.* & intro,index & intro,index\\
-% .*,!chap2 & chap1,chap2,chap3 & chap1,chap3\\
-% .*,!bla & foo,bla,blabla & foo\\
-% .*,!|^|bla|$| & foo,bla,blabla & foo,blabla\\
-% \end{tabular}
-% \end{quote}
-% The example in the last line shows, how the behaviour of package
-% \xpackage{excludeonly} \cite{excludeonly} can be simulated.
-% As the third last line shows, that sometimes `|^|' and `|$|' can
-% be omitted, but this will not work always, shown in the second
-% last line.
-%
-% \subsection{History}
-%
-% Package \xpackage{askinclude} was invented by Pablo A. Straub in 1991
-% and maintained until 1994.
-% ^^A Email address: pablo.straub \symbol{64} gmail.com
-%
-% In October 2007 it was removed from ``TeX Live'' because of
-% the no-commercial license \cite{texlive}. Herbert Vo\ss\ initiated
-% a search for the author in the newsgroup \xnewsgroup{comp.text.tex}
-% \cite{newsthread} to ask him to change the license.
-%
-% It seems that the author could not be reached any more.
-% Joseph Wright suggested a reimplementation that I (HO) have done
-% as package \xpackage{askinc}. Soon it was enhanced by
-% feature requests.
-%
-% Then Ulrike Fischer found email addresses of the original author
-% and Jim Hefferon succeeded in contacting him. He allowed a change
-% of the license to LPPL and the transfer of the maintainership
-% to someone else.
-%
-% Thus I merged both packages as \xpackage{askinclude} in a new
-% major version 2. The license is LPPL.
-%
-% \subsection{New features of version 2}
-%
-% \begin{itemize}
-% \item License is now LPPL.
-% \item A list of \cs{include} files that are detected by the previous
-%   run is printed before the question.
-% \item If the special answer `|?|' is given, then the user is
-%   asked at each \cs{include}.
-% \item Support for regular expressions.
-% \item The remaining stuff in the \xfile{.aux} file does not
-%   cause errors, if the package is removed.
-% \item The use of \cs{includeonly} before the package loading time
-%   is detected and respected by taking precedence. After the package
-%   is loaded, \cs{includeonly} is disabled and prints a warning.
-% \end{itemize}
-%
-% \subsection{Compatibility to version 1}
-%
-% \begin{itemize}
-% \item The user interface of version 1 with its special answers
-%   `|*|', `|-|', and `' remain unchanged, but it is extended by
-%   version 2 with the special answer `|?|' and support for
-%   regular expressions can be enabled.
-% \item As reimplementation the internal macros have changed of course.
-% \item \xfile{.aux} files that are written by version 1.x will work
-%   with version 2.x because \cs{@includeonly} is recognized.
-% \item \LaTeX\ 2.09: The package works as \cs{documentstyle} option
-%   in compatibility mode of \LaTeXe. It is possible that it
-%   will not work in pure \LaTeX\ 2.09.

-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{askinclude}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/askinclude.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/askinclude.pdf}] Documentation.
-% \end{description}
-%
-%
-% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
-% are also available in a TDS compliant ZIP archive. There
-% the packages are already unpacked and the documentation files
-% are generated. The files and directories obey the TDS standard.
-% \begin{description}
-% \item[\CTANinstall{install/macros/latex/contrib/oberdiek.tds.zip}]
-% \end{description}
-% \emph{TDS} refers to the standard ``A Directory Structure
-% for \TeX\ Files'' (\CTANpkg{tds}). Directories
-% with \xfile{texmf} in their name are usually organized this way.
-%
-% \subsection{Bundle installation}
-%
-% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
-% TDS tree (also known as \xfile{texmf} tree) of your choice.
-% Example (linux):
-% \begin{quote}
-%   |unzip oberdiek.tds.zip -d ~/texmf|
-% \end{quote}
-%
-% \subsection{Package installation}
-%
-% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
-% \docstrip\ archive. The files are extracted by running the
-% \xfile{.dtx} through \plainTeX:
-% \begin{quote}
-%   \verb|tex askinclude.dtx|
-% \end{quote}
-%
-% \paragraph{TDS.} Now the different files must be moved into
-% the different directories in your installation TDS tree

-% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
-% TDS installing feature, then some files can already be in the right
-% place, see the documentation of \docstrip.
-%
-% \subsection{Refresh file name databases}
-%
-% If your \TeX~distribution
-% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
-% these. For example, \TeX\,Live\ users run \verb|texhash| or
-% \verb|mktexlsr|.
-%
-% \subsection{Some details for the interested}
-%
-% \paragraph{Unpacking with \LaTeX.}
-% The \xfile{.dtx} chooses its action depending on the format:
-% \begin{description}
-% \item[\plainTeX:] Run \docstrip\ and extract the files.
-% \item[\LaTeX:] Generate the documentation.
-% \end{description}
-% If you insist on using \LaTeX\ for \docstrip\ (really,
-% \docstrip\ does not need \LaTeX), then inform the autodetect routine
-% about your intention:
-% \begin{quote}
-%   \verb|latex \let\install=y\input{askinclude.dtx}|
-% \end{quote}
-% Do not forget to quote the argument according to the demands
-% of your shell.
-%
-% \paragraph{Generating the documentation.}
-% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
-% the documentation. The process can be configured by the
-% configuration file \xfile{ltxdoc.cfg}. For instance, put this
-% line into this file, if you want to have A4 as paper format:
-% \begin{quote}
-%   \verb|\PassOptionsToClass{a4paper}{article}|
-% \end{quote}
-% An example follows how to generate the
-% documentation with pdf\LaTeX:
-% \begin{quote}
-%\begin{verbatim}
-%pdflatex askinclude.dtx
-%bibtex askinclude.aux
-%makeindex -s gind.ist askinclude.idx
-%pdflatex askinclude.dtx
-%makeindex -s gind.ist askinclude.idx
-%pdflatex askinclude.dtx
-%\end{verbatim}

-% \subsection{Introduction}
-%
-% Annotations in the PDF format know entries whose values are
-% integers. This numbers are interpreted as set of flags
-% specifying properties. For example, annotation dictionaries
-% can have a key |/F|. The bits of its integer value
-% are interpreted the following way:
-% \begin{quote}
-% \begin{tabular}{@{}l|l@{}}
-%   Bit position & Property name\\
-%   \hline
-%   1 & Invisible\\
-%   2 & Hidden\\
-%   3 & Print\\
-%   4 & NoZoom\\
-%   5 & NoRotate\\
-%   6 & NoView\\
-%   7 & ReadOnly\\
-%   \dots & \dots
-% \end{tabular}
-% \end{quote}
-% Now, let's see how these values are set in package \xpackage{hyperref}
-% before it uses this package (before v6.77a):
-%\begin{quote}
-%\begin{verbatim}
-%\ifFld@hidden /F 6\else /F 4\fi
-%\end{verbatim}
-%\end{quote}
-% Where are the other flags? The following example for key |/Ff|
-% in a widget annotation
-% supports at least three properties:
-%\begin{quote}
-%\begin{verbatim}
-%\ifFld@multiline
-%  \ifFld@readonly /Ff 4097\else /Ff 4096\fi
-%\else
-%  \ifFld@password
-%    \ifFld@readonly /Ff 8193\else /Ff 8192\fi
-%  \else
-%    \ifFld@readonly /Ff 1\fi
-%  \fi
-%\fi
-%\end{verbatim}
-%\end{quote}
-% But you see the point. It would be a nightmare to continue
-% this way in supporting the missing flag settings. This kind
-% of integers may have up to 32 bits.
-%
-% Therefore I wanted a data structure for setting and
-% clearing individual bits. Also it should provide
-% an export as decimal number. The snipsets above are
-% executed in expansion contexts without \TeX's stomach
-% commands. It would be convenient to have an expandable
-% conversion from the data structure to the integer that
-% gets written to the PDF file.
-%
-% This package \xpackage{bitset} implements such a data
-% structure. The interface is quite close to Java's
-% class |BitSet| in order not to learn to many interfaces
-% for the same kind of data structure.
-%
-% \subsection{Glossary}
-%
-% \begin{description}
-% \item[Bit set:]
-%   A bit set is a vector of bits or flags.
-%   The vector size is unlimited and
-%   grows dynamically. An undefined bit set is treated as bit
-%   set where all bits are cleared.
-%
-%   Bit sets are addressed by name. A name should consists of
-%   letters or digits. Technically it must survive \cs{csname},
-%   see \LaTeX's environment names for other names with such
-%   a constraint. Package \xpackage{babel}'s shorthands are
-%   not supported due to technical reasons. Shorthand support
-%   would break expandable operations.
-% \item[Size:]
-%   A size of a bit set is the number of bits in use.
-%   It's the number of the highest index, incremented by one.
-%   Sizes are in the range |0| up to |2147483647|, the highest
-%   number supported by \TeX.
-% \item[Index:]
-%   Bit positions in a bit set are addressed by an index number.
-%   The bit vector is zero based. The first and least significant
-%   bit is addressed by index |0| and the highest possible bit
-%   by |2147483646|.
-% \item[Bit:]
-%   A bit is enoded as |0| for cleared/disabled or |1| for set/enabled.
-% \end{description}
-%
-% \subsection{Design principles}
-%
-% \begin{description}
-% \item[Name conventions:]
-%   To avoid conflicts with existing macro names, the operations
-%   are prefixed by the package name.
-% \item[Zero based indexes:] The first bit is addressed by zero.
-%   (Convention of array indexing in C, Java, \dots)
-% \item[Unlimited size:]
-%   There is no restriction on the size of a bit set other than
-%   usual memory limitations. \cs{bitsetSetDec} and \cs{bitsetGetDec}
-%   transparently switch to package \xpackage{bigintcalc} if the numbers
-%   get too large for \TeX's number limit.
-% \item[Expandibility:]
-%   Any operation that does not change the bit set is expandable.
-%   And all operations that extract or calculate some result
-%   do this in exact two expansion steps. For example,
-%   a macro \cs{Macro} wants a bit set as decimal number.
-%   But the argument must be a plain number without macros.
-%   Thus you could prefix \cs{bitsetGetDec} with \cs{number}.
-%   However this won't work for bit sets with 31 or more bits
-%   because of \TeX's number limit of $2^{31}-1$.
-%   then just hit the operator with two \cs{expandafter}:
-%   \begin{quote}
-%   |\expandafter\expandafter\expandafter|\\
-%   |\Macro\bitsetGetDec{foo}|
-%   \end{quote}
-%   |\bitsetGetDec| is hit first by the third \cs{expandafter}
-%   and then by the second one.
-% \item[Format independence:] This package is written as \LaTeX\ package,
-%   but it does not depend on \LaTeX. It will also work for other formats
-%   such as \plainTeX.
-% \item[Independence from \TeX\ engines:]
-%   Vanilla \TeX\ is all you need. Calculations are delegated to
-%   packages \xpackage{intcalc} and \xpackage{bigintcalc}.
-%   They don't need any special features, but they will switch
-%   to a little more efficient implementation if features such
-%   as \cs{numexpr} are available.
-% \item[Numeric arguments:] Anything that is accepted by
-%   \cs{number}. If \eTeX\ is detected, also expressions
-%   for \cs{numexpr} are supported. The only exception so far
-%   is the number for \cs{bitsetSetDec}. The number might be too
-%   large for \cs{number} or \cs{numexpr}.
-% \item[Error messages:]
-%   In expandable contexts, only a limited set of \TeX\ primitive
-%   commands work as expected. So called stomach commands behave
-%   like \cs{relax} and don't get expanded or executed.
-%   Unhappily also the error commands belong to this category.
-%   The expandable operations will throw an unknown control
-%   sequence instead to get \TeX's and user's attention.
-%   The name of these control sequences starts with
-%   \cs{BitSetError:} with the type of error after the colon.

-%
-% \subsection{Package loading}
-%
-% The package can be used as normal \LaTeX\ package:
-%\begin{quote}
-%|\usepackage{bitset}|
-%\end{quote}
-% Also \plainTeX\ is supported:
-%\begin{quote}
-%|\input bitset.sty\relax|
-%\end{quote}
-%
-% \subsection{Operators}
-%
-% The following macros work on and with bit sets.
-% A bit set \meta{BitSet} is represented by a name.
-% The should consist of letters and digits. Technically
-% it must survive \cs{csname}. It is the same constraint
-% that must be satisfied by label or environment names
-% in \LaTeX.
-%
-% However active characters that are shorthands
-% of package \xpackage{babel} are not supported.
-% Support for shorthands works by an assignment.
-% But many operators
-% such as \cs{bitsetGetDec} must be usable in expandable
-% contexts. There assignments will not be executed in the
-% best case or they will cause errors.
-%
-% The bits in a bit set are addressed by non-negative
-% integers starting from zero. Thus negative index
-% numbers cause an error message. Because index numbers
-% are \TeX\ numbers. The largest index is 2147483647.
-% But in practice memory limits and patience limits
-% will be very likely reached much before.
-%
-% \subsubsection{Miscellaneous}\label{sec:misc}
-%
-% There isn't a separate operation for bit set creation.
-% For simplicity an undefined bit set is treated as bit set
-% with all bits cleared.
-%
-% \begin{declcs}{bitsetReset} \M{BitSet}
-% \end{declcs}
-% Macro \cs{bitsetReset} clears all bits. The result is an
-% empty bit set. It may also be used as replacement for
-% an operation ``new'', because an undefined bit set is defined
-% afterwards.
-%
-% \begin{declcs}{bitsetLet} \M{BitSet A} \M{BitSet B}
-% \end{declcs}
-% Macro \cs{bitsetLet} performs a simple assignment similar
-% to \TeX's \cs{let}. After the operation \meta{BitSet A} has
-% the same value as \meta{BitSet B}. If \meta{BitSet B} is
-% undefined, then \meta{BitSet A} will be the empty bit set.
-%
-% Note: If \meta{BitSet A} exists, it will be overwritten.
-%
-% \subsubsection{Import}\label{sec:import}
-%
-% \begin{declcs}{bitsetSetBin} \M{BitSet} \M{BinaryNumber}\\
-%   \cs{bitsetSetOct} \M{BitSet} \M{OctalNumber}\\
-%   \cs{bitsetSetHex} \M{BitSet} \M{HexadecimalNumber}
-% \end{declcs}
-% The numbers are interpreted as bit vectors and the flags in
-% the bit \meta{BitSet} set are set accordingly.
-% These numeric arguments are the only arguments where
-% spaces are allowed. Then the numbers are easier to read.
-%
-% \begin{declcs}{bitsetSetDec} \M{BitSet} \M{DecimalNumber}
-% \end{declcs}
-% Macro \cs{bitsetSetDec} uses \meta{DecimalNumber} to
-% set the bit set \meta{BitSet}.
-% The numeric argument must expand
-% to a plain number consisting of decimal digits without
-% command tokens or spaces. Internally this argument is
-% expanded only. It cannot be passed to \cs{number} or
-% \cs{numexpr}, because the number may be too large for them.
-% However \cs{number} or |\the\numexpr| may be used
-% explicitely. This also helps for unexpandable number
-% command tokens or registers (\cs{z@}, \cs{@ne}, \cs{count@}, \dots).
-% Also \LaTeX'\ \cs{value} needs prefixing:
-% \begin{quote}
-% |\bitsetSetDec{foo}{\number\value{bar}}|
-% \end{quote}
-%
-% \subsubsection{Export}\label{sec:export}
-%
-% \begin{declcs}{bitsetGetBin} \M{BitSet} \M{MinSize}\\
-%   \cs{bitsetGetOct} \M{BitSet} \M{MinSize}\\
-%   \cs{bitsetGetHex} \M{BitSet} \M{MinSize}
-% \end{declcs}
-% These macros returns the bit set as binary, octal or hexadecimal
-% number. If the bit size is smaller than \meta{MinSize} the gap is
-% filled with leading zeros.
-% Example:
-% \begin{quote}
-% |\bitsetReset{abc}|\\
-% |\bitsetSet{abc}{2}|\\
-% |\bitsetGetBin{abc}{8}| $\rightarrow$ |00000100|\\
-% |\bitsetSet{abc}{5}\bitsetSet{abc}{7}|\\
-% |\bitsetGetHex{abc}{16}| $\rightarrow$ |00A2|
-% \end{quote}
-% Macro \cs{bitsetGetHex} uses the uppercase letters |A| to |F|.
-% The catcode of the letters is one of 11 (letter) or 12 (other).
-%
-% \begin{declcs}{bitsetGetDec} \M{BitSet}
-% \end{declcs}
-% Macro \cs{bitsetGetDec} returns the bit set \meta{BitSet} as
-% decimal number. The returned number can be larger than
-% \TeX's number limit of $2^{31}-1$.
-%
-% \subsubsection{Logical operators}\label{sec:log}
-%
-% \begin{declcs}{bitsetAnd} \M{BitSet A} \M{BitSet B}
-% \end{declcs}
-% $A_{\text{new}} \mathrel{\mathop{:}}= A_{\text{old}}
-% \mathbin{\text{and}} B \qquad (\forall\, \text{bits})$
-%
-% \begin{declcs}{bitsetAndNot} \M{BitSet A} \M{BitSet B}
-% \end{declcs}
-% $A_{\text{new}} \mathrel{\mathop{:}}= A_{\text{old}}
-% \mathbin{\text{and}} (\text{not}\,B) \qquad (\forall\, \text{bits})$
-%
-% \begin{declcs}{bitsetOr} \M{BitSet A} \M{BitSet B}
-% \end{declcs}
-% $A_{\text{new}} \mathrel{\mathop{:}}= A_{\text{old}}
-% \mathbin{\text{or}} B \qquad (\forall\, \text{bits})$
-%
-% \begin{declcs}{bitsetXor} \M{BitSet A} \M{BitSet B}
-% \end{declcs}
-% $A_{\text{new}} \mathrel{\mathop{:}}= A_{\text{old}}
-% \mathbin{\text{xor}} B \qquad (\forall\, \text{bits})$
-%
-% \subsubsection{Shifting}\label{sec:shift}
-%
-% \begin{declcs}{bitsetShiftLeft} \M{BitSet} \M{ShiftAmount}\\
-%   \cs{bitsetShiftRight} \M{BitSet} \M{ShiftAmount}
-% \end{declcs}
-% A left shift by one is a multiplication by two, thus left shifting
-% moves the flags to higher positions. The new created low positions
-% are filled by zeros.
-%
-% A right shift is the opposite, dividing by two, movint the bits
-% to lower positions. The number will become smaller, the lowest
-% bits are lost.
-%
-% If the \meta{ShiftAmount} is negative, it reverts the meaning of
-% the shift operation. A left shift becomes a right shift.
-% A \meta{ShiftAmount} of zero is ignored.

-% \subsubsection{Bit manipulation}\label{sec:bitman}
-%
-% \begin{declcs}{bitsetClear} \M{BitSet} \M{Index}\\
-%   \cs{bitsetSet} \M{BitSet} \M{Index}\\
-%   \cs{bitsetFlip} \M{BitSet} \M{Index}
-% \end{declcs}
-% This macros manipulate a single bit in \meta{BitSet} addressed
-% by \cs{Index}. Macro \cs{bitsetClear} disables the bit,
-% \cs{bitsetSet} enables it and \cs{bitsetFlip} reverts the current
-% setting of the bit.
-%
-% \begin{declcs}{bitsetSetValue} \M{BitSet} \M{Index} \M{Bit}
-% \end{declcs}
-% Macro \cs{bitsetSetValue} puts bit \meta{Bit} at position \meta{Index}
-% in bit set \meta{BitSet}. \meta{Bit} must be a valid \TeX\ number
-% equals to zero (disabled/cleared) or one (enabled/set).
-%
-% \subsubsection{Bit retrieval}\label{sec:bitret}
-%
-% \begin{declcs}{bitsetGet} \M{BitSet} \M{Index}
-% \end{declcs}
-% Macro \cs{bitsetGet} extracts the status of the bit at
-% position \meta{Index} in bit set \meta{BitSet}.
-% Digit |1| is returned if the bit is set/enabled. If the
-% bit is cleared/disabled and in cases of an undefined bitset or
-% an index number out of range the return value is |0|.
-%
-% \begin{declcs}{bitsetNextClearBit} \M{BitSet} \M{Index}
-% \end{declcs}
-% Starting at position \meta{Index} (inclusive) the bits
-% are inspected. The first position without a set bit is returned.
-% Possible results are decimal numbers: \meta{Index}, \meta{Index} + 1,
-% \dots, ($\infty$)
-%
-% \begin{declcs}{bitsetNextSetBit} \M{BitSet} \M{Index}
-% \end{declcs}
-% Starting at position \meta{Index} (inclusive) the bits are
-% inspected and the index position of the first found set bit
-% is returned. If there isn't such a bit, then the result is
-% |-1|. In summary possible results are decimal numbers:
-% |-1|, \meta{Index}, \meta{Index} + 1, \dots, ($\infty$)
-%
-% \begin{declcs}{bitsetGetSetBitList} \M{BitSet}
-% \end{declcs}
-% Macro \cs{bitsetGetSetBitList} is an application for
-% \cs{bitsetNextSetBit}. The set bits are iterated and
-% returned as comma separated list of index positions
-% in increasing order. The list is empty in case of
-% an empty bit set.
-%
-% \subsubsection{Bit set properties}\label{sec:prop}
-%
-% \begin{declcs}{bitsetSize} \M{BitSet}
-% \end{declcs}
-% Macro \cs{bitsetSize} returns number of bits in use.
-% It is the same as the index number of the highest set/enabled bit
-% incremented by one.
-%
-% \begin{declcs}{bitsetCardinality} \M{BitSet}
-% \end{declcs}
-% Macro \cs{bitsetCardinality} counts the number of set/enabled bits.
-%
-% \subsubsection{Queries}\label{sec:query}
-%
-% Also the query procedures are expandable. They ask for a piece
-% of information about a bit set and execute code depending
-% on the answer.
-%
-% \begin{declcs}{bitsetIsDefined} \M{BitSet} \M{Then} \M{Else}
-% \end{declcs}
-% If the bit set with the name \meta{BitSet} exists the code
-% given in \meta{Then} is executed, otherwise \meta{Else} is used.
-%
-% \begin{declcs}{bitsetIsEmpty} \M{BitSet} \M{Then} \M{Else}
-% \end{declcs}
-% If the bit set \meta{BitSet} exists and at least one bit
-% is set/enabled, the code in \meta{Then} is executed,
-% \meta{Else} otherwise.
-%
-% \begin{declcs}{bitsetEquals} \M{BitSet A} \M{BitSet B} \M{Then} \M{Else}
-% \end{declcs}
-% Both bit sets are equal if and only if either both are undefined
-% or both are defined and represents the same bit values at the
-% same positions. Thus this definition is reflexive, symmeric,
-% and transitive, enough for an equivalent relation.
-%
-% \begin{declcs}{bitsetIntersects} \M{BitSet A} \M{BitSet B} \M{Then} \M{Else}
-% \end{declcs}
-% If and only if \meta{BitSet A} and \meta{BitSet B} have
-% at least one bit at the same position that is set, then
-% code part \meta{Then} is executed.
-%
-% \begin{declcs}{bitsetQuery} \M{BitSet} \M{Index} \M{Then} \M{Else}
-% \end{declcs}
-% It's just a wrapper for \cs{bitsetGet}. If the bit at position
-% \meta{Index} is enabled, code \meta{Then} is called.
-%
-% \StopEventually{

-%
-% \section{Implementation}
-%
-% The internal format of a bit set is quite simple, a sequence
-% of digits |0| and |1|. The least significant bit is left.
-% A bit set without any flag set is encoded by |0|. Also
-% undefined bit sets are treated that way. After the
-% highest bit that is set there are no further zeroes.
-% A regular expression of valid bit sets values:
-% \begin{quote}
-%  |0|\string||[01]*1|

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{bitset}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/bitset.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/bitset.pdf}] Documentation.
-% \end{description}
-%
-%
-% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
-% are also available in a TDS compliant ZIP archive. There
-% the packages are already unpacked and the documentation files
-% are generated. The files and directories obey the TDS standard.
-% \begin{description}
-% \item[\CTANinstall{install/macros/latex/contrib/oberdiek.tds.zip}]
-% \end{description}
-% \emph{TDS} refers to the standard ``A Directory Structure
-% for \TeX\ Files'' (\CTANpkg{tds}). Directories
-% with \xfile{texmf} in their name are usually organized this way.
-%
-% \subsection{Bundle installation}
-%
-% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
-% TDS tree (also known as \xfile{texmf} tree) of your choice.
-% Example (linux):
-% \begin{quote}
-%   |unzip oberdiek.tds.zip -d ~/texmf|
-% \end{quote}
-%
-% \subsection{Package installation}
-%
-% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
-% \docstrip\ archive. The files are extracted by running the
-% \xfile{.dtx} through \plainTeX:
-% \begin{quote}
-%   \verb|tex bitset.dtx|
-% \end{quote}
-%
-% \paragraph{TDS.} Now the different files must be moved into
-% the different directories in your installation TDS tree
-% (also known as \xfile{texmf} tree):

-% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
-% TDS installing feature, then some files can already be in the right
-% place, see the documentation of \docstrip.
-%
-% \subsection{Refresh file name databases}
-%
-% If your \TeX~distribution
-% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
-% these. For example, \TeX\,Live\ users run \verb|texhash| or
-% \verb|mktexlsr|.
-%
-% \subsection{Some details for the interested}
-%
-% \paragraph{Unpacking with \LaTeX.}
-% The \xfile{.dtx} chooses its action depending on the format:
-% \begin{description}
-% \item[\plainTeX:] Run \docstrip\ and extract the files.
-% \item[\LaTeX:] Generate the documentation.
-% \end{description}
-% If you insist on using \LaTeX\ for \docstrip\ (really,
-% \docstrip\ does not need \LaTeX), then inform the autodetect routine
-% about your intention:
-% \begin{quote}
-%   \verb|latex \let\install=y\input{bitset.dtx}|
-% \end{quote}
-% Do not forget to quote the argument according to the demands
-% of your shell.
-%
-% \paragraph{Generating the documentation.}
-% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
-% the documentation. The process can be configured by the
-% configuration file \xfile{ltxdoc.cfg}. For instance, put this
-% line into this file, if you want to have A4 as paper format:
-% \begin{quote}
-%   \verb|\PassOptionsToClass{a4paper}{article}|
-% \end{quote}
-% An example follows how to generate the
-% documentation with pdf\LaTeX:
-% \begin{quote}
-%\begin{verbatim}
-%pdflatex bitset.dtx
-%makeindex -s gind.ist bitset.idx
-%pdflatex bitset.dtx
-%makeindex -s gind.ist bitset.idx
-%pdflatex bitset.dtx

-% Macro \meta{cmd} is defined with the contents

-%
-%    \begin{macro}{\CatchFile@Input}
-%    The package needs the expandable primitive \cs{input}.
-%    However there are formats that redefine it. For example,
-%    \LaTeX's \cs{input} is not expandable, but it stores
-%    the primitive in \cs{@@input}. The third possibility
-%    is \cs{pdfprimitive}, introduced in \pdfTeX\ 1.40.0.
-%
-%    Thus we try to find the primitive and store it in
-%    \cs{CatchFile@Input}. If it is used, it must be expanded
-%    twice (because of the solution with \cs{pdfprimitive}).

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{catchfile}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/catchfile.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/catchfile.pdf}] Documentation.
-% \end{description}
-%
-%
-% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
-% are also available in a TDS compliant ZIP archive. There
-% the packages are already unpacked and the documentation files
-% are generated. The files and directories obey the TDS standard.
-% \begin{description}
-% \item[\CTANinstall{install/macros/latex/contrib/oberdiek.tds.zip}]
-% \end{description}
-% \emph{TDS} refers to the standard ``A Directory Structure
-% for \TeX\ Files'' (\CTANpkg{tds}). Directories
-% with \xfile{texmf} in their name are usually organized this way.
-%
-% \subsection{Bundle installation}
-%
-% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
-% TDS tree (also known as \xfile{texmf} tree) of your choice.
-% Example (linux):
-% \begin{quote}
-%   |unzip oberdiek.tds.zip -d ~/texmf|
-% \end{quote}
-%
-% \subsection{Package installation}
-%
-% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
-% \docstrip\ archive. The files are extracted by running the
-% \xfile{.dtx} through \plainTeX:
-% \begin{quote}
-%   \verb|tex catchfile.dtx|
-% \end{quote}
-%
-% \paragraph{TDS.} Now the different files must be moved into
-% the different directories in your installation TDS tree
-% (also known as \xfile{texmf} tree):

-% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
-% TDS installing feature, then some files can already be in the right
-% place, see the documentation of \docstrip.
-%
-% \subsection{Refresh file name databases}
-%
-% If your \TeX~distribution
-% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
-% these. For example, \TeX\,Live\ users run \verb|texhash| or
-% \verb|mktexlsr|.
-%
-% \subsection{Some details for the interested}
-%
-% \paragraph{Unpacking with \LaTeX.}
-% The \xfile{.dtx} chooses its action depending on the format:
-% \begin{description}
-% \item[\plainTeX:] Run \docstrip\ and extract the files.
-% \item[\LaTeX:] Generate the documentation.
-% \end{description}
-% If you insist on using \LaTeX\ for \docstrip\ (really,
-% \docstrip\ does not need \LaTeX), then inform the autodetect routine
-% about your intention:
-% \begin{quote}
-%   \verb|latex \let\install=y\input{catchfile.dtx}|
-% \end{quote}
-% Do not forget to quote the argument according to the demands
-% of your shell.
-%
-% \paragraph{Generating the documentation.}
-% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
-% the documentation. The process can be configured by the
-% configuration file \xfile{ltxdoc.cfg}. For instance, put this
-% line into this file, if you want to have A4 as paper format:
-% \begin{quote}
-%   \verb|\PassOptionsToClass{a4paper}{article}|
-% \end{quote}
-% An example follows how to generate the
-% documentation with pdf\LaTeX:
-% \begin{quote}
-%\begin{verbatim}
-%pdflatex catchfile.dtx
-%makeindex -s gind.ist catchfile.idx
-%pdflatex catchfile.dtx
-%makeindex -s gind.ist catchfile.idx
-%pdflatex catchfile.dtx
-%\end{verbatim}
-% \end{quote}

-% \begin{abstract}
-% Package \xpackage{listings} does not support files with multi-byte
-% encodings such as UTF-8. In case of \cs{lstinputlisting} a simple
-% workaround is possible if an one-byte encoding exists that the file
-% can be converted to. Also \eTeX\ and \pdfTeX\ regardless of its mode
-% are required.

-%
-% \subsection{User interface}
-%
-% Load this package after or instead of package \xpackage{listings}
-% \cite{listings}.
-% The package does not define own options and passes given options to
-% package \xpackage{listings}.
-%
-% The syntax of package \xpackage{listings}' key \xoption{inputencoding}
-% is extended:
-% \begin{quote}
-%   |inputencoding=utf8/|\meta{one-byte-encoding}\\
-%   Example: |inputencoding=utf8/latin1|
-% \end{quote}
-% That means the file is encoded in UTF-8 and can
-% be converted to the given \meta{one-byte-encoding}.
-% The available encodings for \meta{one-byte-encoding} are
-% listed in section ``1.2 Supported encodings'' of
-% package \xpackage{stringenc}'s documentation \cite{stringenc}.
-% Of course, the encoding must encode its characters with
-% one byte exactly. This excludes the unicode encodings
-% (\xoption{utf8}, \xoption{utf16}, \dots).
-%
-% Only \cs{lstinputlisting} is supported by the syntax extension
-% of key \xoption{inputencoding}.
-%
-% Internally package \xpackage{listingsutf8} reads the file as binary file
-% via primitives of \pdfTeX\ (\cs{pdffiledump}). Then the file
-% contents is converted as string using package \xpackage{stringenc} and
-% finally the string is read as virtual file by \eTeX's \cs{scantokens}.
-%
-% \subsection{Future}
-%
-% Workarounds are not provided for
-% \begin{itemize}
-% \item \cs{lstinline}
-% \item Environment |lstlisting|.
-% \item Environments defined by \cs{lstnewenvironment}.
-% \end{itemize}
-% Perhaps someone will find time to extend package \xpackage{listings}
-% with full native support for UTF-8. Then this package would become obsolete.

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{listingsutf8}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/listingsutf8.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/listingsutf8.pdf}] Documentation.
-% \end{description}
-%
-%
-% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
-% are also available in a TDS compliant ZIP archive. There
-% the packages are already unpacked and the documentation files
-% are generated. The files and directories obey the TDS standard.
-% \begin{description}
-% \item[\CTANinstall{install/macros/latex/contrib/oberdiek.tds.zip}]
-% \end{description}
-% \emph{TDS} refers to the standard ``A Directory Structure
-% for \TeX\ Files'' (\CTANpkg{tds}). Directories
-% with \xfile{texmf} in their name are usually organized this way.
-%
-% \subsection{Bundle installation}
-%
-% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
-% TDS tree (also known as \xfile{texmf} tree) of your choice.
-% Example (linux):
-% \begin{quote}
-%   |unzip oberdiek.tds.zip -d ~/texmf|
-% \end{quote}
-%
-% \subsection{Package installation}
-%
-% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
-% \docstrip\ archive. The files are extracted by running the
-% \xfile{.dtx} through \plainTeX:
-% \begin{quote}
-%   \verb|tex listingsutf8.dtx|
-% \end{quote}
-%
-% \paragraph{TDS.} Now the different files must be moved into
-% the different directories in your installation TDS tree
-% (also known as \xfile{texmf} tree):

-% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
-% TDS installing feature, then some files can already be in the right
-% place, see the documentation of \docstrip.
-%
-% \subsection{Refresh file name databases}
-%
-% If your \TeX~distribution
-% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
-% these. For example, \TeX\,Live\ users run \verb|texhash| or
-% \verb|mktexlsr|.
-%
-% \subsection{Some details for the interested}
-%
-% \paragraph{Unpacking with \LaTeX.}
-% The \xfile{.dtx} chooses its action depending on the format:
-% \begin{description}
-% \item[\plainTeX:] Run \docstrip\ and extract the files.
-% \item[\LaTeX:] Generate the documentation.
-% \end{description}
-% If you insist on using \LaTeX\ for \docstrip\ (really,
-% \docstrip\ does not need \LaTeX), then inform the autodetect routine
-% about your intention:
-% \begin{quote}
-%   \verb|latex \let\install=y\input{listingsutf8.dtx}|
-% \end{quote}
-% Do not forget to quote the argument according to the demands
-% of your shell.
-%
-% \paragraph{Generating the documentation.}
-% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
-% the documentation. The process can be configured by the
-% configuration file \xfile{ltxdoc.cfg}. For instance, put this
-% line into this file, if you want to have A4 as paper format:
-% \begin{quote}
-%   \verb|\PassOptionsToClass{a4paper}{article}|
-% \end{quote}
-% An example follows how to generate the
-% documentation with pdf\LaTeX:
-% \begin{quote}
-%\begin{verbatim}
-%pdflatex listingsutf8.dtx
-%makeindex -s gind.ist listingsutf8.idx
-%pdflatex listingsutf8.dtx
-%makeindex -s gind.ist listingsutf8.idx

-% \begin{abstract}
-% This package implements \pdfTeX's escape features
-% (\cs{pdfescapehex}, \cs{pdfunescapehex}, \cs{pdfescapename},
-% \cs{pdfescapestring}) using \TeX\ or \eTeX.
-% \end{abstract}
-%
-% \tableofcontents
-%
-% \section{Documentation}
-%
-% \begin{declcs}{EdefEscapeHex} \M{cmd} \M{string}\\
-%  \cs{EdefUnescapeHex} \M{cmd} \M{string}\\
-%  \cs{EdefEscapeName} \M{cmd} \M{string}\\
-%  \cs{EdefEscapeString} \M{cmd} \M{string}
-% \end{declcs}
-% These commands converts \meta{string} and stores the result
-% in macro \meta{cmd}. The conversion result is the same
-% as the conversion of the corresponding \pdfTeX's primitives.
-% Note that the argument \meta{string} is expanded before
-% the conversion.
-%
-% For example, if \pdfTeX\ \textgreater= 1.30 is present,
-% then \cs{EdefEscapeHex}
-% becomes to:
-% \begin{quote}
-%\begin{verbatim}
-%\def\EdefEscapeHex#1#2{%
-%  \edef#1{\pdfescapehex{#2}}%
-%}
-%\end{verbatim}
-% \end{quote}
-% The package provides implementations for the case that \pdfTeX\ is
-% not present (or too old). Even \eTeX\ can be missing, however it is
-% used if it is detected.
-%
-% \paragraph{Babel.}
-% The input strings may contain shorthand characters of package
-% \xpackage{babel}.
-%
-% \subsection{Additional unescape macros}
-%
-% \begin{declcs}{EdefUnescapeName} \M{cmd} \M{string}
-% \end{declcs}
-% Sequences of a hash sign with two hexadecimal digits are
-% converted to the corresponding character (PDF-1.2).
-% A hash sign that is not followed by two hexadecimal digits
-% is left unchanged. The catcodes in the result string follow
-% TeX's conventions. The space has catcode 10 (space) and
-% the other characters have catcode 12 (other).
-%
-% \begin{declcs}{EdefUnescapeString} \M{cmd} \M{string}
-% \end{declcs}
-% Macro \meta{cmd} stores the unescaped string in \meta{string}.
-% All the rules for literal strings are implemented, see
-% PDF specification.
-% The catcodes in the result string follow TeX's conventions.
-%
-% \subsection{Sanitizing macro}
-%
-% \begin{declcs}{EdefSanitize} \M{cmd} \M{string}
-% \end{declcs}
-% Argument \meta{string} is expanded, converted to a string
-% of tokens with catcode 12 (other) and space tokens, and
-% stored in macro \meta{cmd}.

-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{pdfescape}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/pdfescape.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/pdfescape.pdf}] Documentation.
-% \end{description}
-%
-%
-% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
-% are also available in a TDS compliant ZIP archive. There
-% the packages are already unpacked and the documentation files
-% are generated. The files and directories obey the TDS standard.
-% \begin{description}
-% \item[\CTANinstall{install/macros/latex/contrib/oberdiek.tds.zip}]
-% \end{description}
-% \emph{TDS} refers to the standard ``A Directory Structure
-% for \TeX\ Files'' (\CTANpkg{tds}). Directories
-% with \xfile{texmf} in their name are usually organized this way.

-% \subsection{Bundle installation}
-%
-% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
-% TDS tree (also known as \xfile{texmf} tree) of your choice.
-% Example (linux):
-% \begin{quote}
-%   |unzip oberdiek.tds.zip -d ~/texmf|
-% \end{quote}
-%
-% \subsection{Package installation}
-%
-% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
-% \docstrip\ archive. The files are extracted by running the
-% \xfile{.dtx} through \plainTeX:
-% \begin{quote}
-%   \verb|tex pdfescape.dtx|
-% \end{quote}
-%
-% \paragraph{TDS.} Now the different files must be moved into

-% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
-% TDS installing feature, then some files can already be in the right
-% place, see the documentation of \docstrip.
-%
-% \subsection{Refresh file name databases}
-%
-% If your \TeX~distribution
-% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
-% these. For example, \TeX\,Live\ users run \verb|texhash| or
-% \verb|mktexlsr|.
-%
-% \subsection{Some details for the interested}
-%
-% \paragraph{Unpacking with \LaTeX.}
-% The \xfile{.dtx} chooses its action depending on the format:
-% \begin{description}
-% \item[\plainTeX:] Run \docstrip\ and extract the files.
-% \item[\LaTeX:] Generate the documentation.
-% \end{description}
-% If you insist on using \LaTeX\ for \docstrip\ (really,
-% \docstrip\ does not need \LaTeX), then inform the autodetect routine
-% about your intention:
-% \begin{quote}
-%   \verb|latex \let\install=y\input{pdfescape.dtx}|
-% \end{quote}
-% Do not forget to quote the argument according to the demands
-% of your shell.
-%
-% \paragraph{Generating the documentation.}
-% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
-% the documentation. The process can be configured by the
-% configuration file \xfile{ltxdoc.cfg}. For instance, put this
-% line into this file, if you want to have A4 as paper format:
-% \begin{quote}
-%   \verb|\PassOptionsToClass{a4paper}{article}|
-% \end{quote}
-% An example follows how to generate the
-% documentation with pdf\LaTeX:
-% \begin{quote}
-%\begin{verbatim}
-%pdflatex pdfescape.dtx
-%makeindex -s gind.ist pdfescape.idx
-%pdflatex pdfescape.dtx
-%makeindex -s gind.ist pdfescape.idx
-%pdflatex pdfescape.dtx

-% \begin{abstract}
-% There are macro and environment arguments that expect numbers
-% that will internally be multiplicated with \cs{unitlength}.
-% This package extends the syntax of these arguments that
-% dimens with calculation support can be added for these arguments.
-% \end{abstract}
-%
-% \tableofcontents
-%
-% \section{User interface}
-%
-% \subsection{Introduction}
-%
-% The environment |picture| and macros such as \cs{put}, \cs{line},
-% \cs{vector} and other macros have arguments that expect numbers
-% that are used as factor for \cs{unitlength}.
-% This package redefines such macros and adds code that detects
-% whether such an argument is given as number or as length.
-% In the latter case, the length is used directly without multiplying
-% with \cs{unitlength}.
-%
-% \subsection{Options}
-%
-% Depending on the available features, also length expressions
-% can be given. Option \xoption{calc} loads package \xpackage{calc}.
-% Then expressions of these package may be used.
-% Otherwise \xoption{etex} wraps the length argument inside
-% \cs{dimexpr}\dots\cs{relax}, if \eTeX\ is available. Otherwise
-% option \xoption{plain} uses plain assignments without calculation
-% support.
-%
-% The default is \xoption{calc} if package \xpackage{calc}
-% is loaded before package \xoption{picture}. If you specify
-% option \xoption{calc} the loading of \xpackage{calc} is ensured.
-% Otherwise package \xpackage{picture} looks whether \cs{dimexpr}
-% is available and uses then option \xoption{etex} as default.
-% If \eTeX\ also could not be found, then \xoption{plain} is used.
-%
-% \subsection{Example}
-%
-%    \begin{macrocode}
-%<*example>
-\documentclass{article}
-
-\usepackage[calc]{picture}
-
-\begin{document}
-
-\setlength{\unitlength}{1pt}
-
-\begin{picture}(\widthof{Hello World}, 10mm)
-  \put(0, 0){\makebox(0,0)[lb]{Hello World}}%
-  \put(0, \heightof{Hello World} + \fboxsep){%
-    \line(1, 0){\widthof{Hello World}}%
-  }%
-  \put(\widthof{Hello World}, 10mm){%
-    \line(0, -1){10mm}%
-  }%
-\end{picture}
-
-\end{document}
-%</example>
-%    \end{macrocode}
-%
-% \subsection{Supported packages}
-%
-% Packages \xpackage{pspicture} and \xpackage{pict2e} are supported,
-% but they must be loaded before package \xpackage{picture}.
-%
-% New macros can be supported by \cs{picture@redefine}.
-% The first argument is the macro which contains the arguments
-% in its parameter text that you want to support by package \xpackage{picture}.
-% The second argument contains the parameter text. Change \# to \& for
-% the arguments in question.
-% Examples (already used by package \xpackage{picture}):
-% \begin{quote}
-% |\picture@redefine\put{(&1,&2)}|\\
-% |\picture@redefine\line{(#1,#2)&3}|
-% \end{quote}

-% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
-% TDS installing feature, then some files can already be in the right
-% place, see the documentation of \docstrip.
-%
-% \subsection{Refresh file name databases}
-%
-% If your \TeX~distribution
-% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
-% these. For example, \TeX\,Live\ users run \verb|texhash| or
-% \verb|mktexlsr|.
-%
-% \subsection{Some details for the interested}
-%
-% \paragraph{Unpacking with \LaTeX.}
-% The \xfile{.dtx} chooses its action depending on the format:
-% \begin{description}
-% \item[\plainTeX:] Run \docstrip\ and extract the files.
-% \item[\LaTeX:] Generate the documentation.
-% \end{description}
-% If you insist on using \LaTeX\ for \docstrip\ (really,
-% \docstrip\ does not need \LaTeX), then inform the autodetect routine
-% about your intention:
-% \begin{quote}
-%   \verb|latex \let\install=y\input{picture.dtx}|
-% \end{quote}
-% Do not forget to quote the argument according to the demands
-% of your shell.
-%
-% \paragraph{Generating the documentation.}
-% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
-% the documentation. The process can be configured by the
-% configuration file \xfile{ltxdoc.cfg}. For instance, put this
-% line into this file, if you want to have A4 as paper format:
-% \begin{quote}
-%   \verb|\PassOptionsToClass{a4paper}{article}|
-% \end{quote}
-% An example follows how to generate the
-% documentation with pdf\LaTeX:
-% \begin{quote}
-%\begin{verbatim}
-%pdflatex picture.dtx
-%makeindex -s gind.ist picture.idx
-%pdflatex picture.dtx
-%makeindex -s gind.ist picture.idx
-%pdflatex picture.dtx
-%\end{verbatim}
-% \end{quote}
-%
-% \begin{History}
-%   \begin{Version}{2006/08/26 v1.0}
-%   \item
-%     First released version. (First start of the project was June/July 2002.)
-%   \end{Version}
-%   \begin{Version}{2007/04/11 v1.1}
-%   \item
-%     Line ends sanitized.
-%   \end{Version}
-%   \begin{Version}{2008/11/26 v1.2}

-%     packages''.
-%   \item

-% \section{Documentation}
-%
-% \subsection{Introduction}
-%
-% \LaTeX\ supports the direct use of 8-bit characters by means
-% of package \xpackage{inputenc}. However you must know
-% and specify the encoding, e.g.:
-% \begin{quote}
-%   \ttfamily
-%   |\documentclass{article}|\\
-%   |\usepackage[|\EM{latin1}|]{inputenc}|\\
-%   |% or \usepackage[|\EM{utf8}|]{inputenc}|\\
-%   |% or \usepackage[|\EM{??}|]{inputenc}|\\
-%   |\begin{document}|\\
-%   |  |\ExampleText\\
-%   |\end{document}|
-% \end{quote}
-%
-% If the document is transferred in an environment that
-% uses a different encoding, then there are programs that
-% convert the input characters. Examples for conversion
-% of file \xfile{test.tex}
-% from encoding latin1 (ISO-8859-1) to UTF-8:
-% \begin{quote}
-%   \ttfamily
-%   |recode ISO-8859-1..UTF-8 test.tex|\\
-%   |recode latin1..utf8 test.tex|\\
-%   |iconv --from-code ISO-8859-1|\\
-%   \hphantom{iconv}| --to-code UTF-8|\\
-%   \hphantom{iconv}| --output testnew.tex|\\
-%   \hphantom{iconv}| test.tex|\\
-%   |iconv -f latin1 -t utf8 -o testnew.tex test.tex|
-% \end{quote}
-% However, the encoding name for package \xpackage{inputenc}
-% must be changed:
-% \begin{quote}
-%    |\usepackage[latin1]{inputenc}| $\rightarrow$
-%    |\usepackage[utf8]{inputenc}|\kern-4pt\relax
-% \end{quote}
-% Of course, unless you are using some clever editor
-% that knows package \xpackage{inputenc}, recodes
-% the file and adjusts the option at the same time.
-% But most editors can perhaps recode the file, but
-% they let the option untouched.
-%
-% Therefore package \xpackage{selinput} chooses another way for
-% specifying the input encoding. The encoding name is not needed
-% at all. Some 8-bit characters are identified by their glyph
-% name and the package chooses an appropriate encoding, example:
-% \begin{quote}
-%   \ttfamily
-%   |\documentclass{article}|\\
-%   |\usepackage{selinput}|\\
-%   |\SelectInputMappings{|\\
-%   |  adieresis={|\EM{\"a}|}|,\\
-%   |  germandbls={|\EM{\ss}|}|,\\
-%   |  Euro={|\EM{\texteuro}|}|,\\
-%   |}|\\
-%   |\begin{document}|\\
-%   |  |\ExampleText\\
-%   |\end{document}|
-% \end{quote}
-%
-% \subsection{User interface}
-%
-% \begin{declcs}{SelectInputEncodingList} \M{encoding list}
-% \end{declcs}
-% \cs{SelectInputEncodingList} expects a comma separated list of
-% encoding names. Example:
-% \begin{quote}
-%   |\SelectInputEncodingList{utf8,ansinew,mac-roman}|
-% \end{quote}
-% The encodings of package \xpackage{inputenx} are used as default.
-%
-% \begin{declcs}{SelectInputMappings} \M{mapping pairs}
-% \end{declcs}
-% A mapping pair consists of a glyph name and its input
-% character:
-% \begin{quote}
-%   |\SelectInputMappings{|\\
-%   |  adieresis={|\EM{\"a}|}|,\\
-%   |  germandbls={|\EM{\ss}|}|,\\
-%   |  Euro={|\EM{\texteuro}|}|,\\
-%   |}|
-% \end{quote}
-% The supported glyph names can be found in file \xfile{ix-name.def}
-% of project \xpackage{inputenx} \cite{inputenx}. The names are
-% basically taken from Adobe's glyphlists \cite{adobe:glyphlist,adobe:aglfn}.
-% As many pairs are needed as necessary to identify the encoding.
-% Example with insufficient pairs:
-% \begin{quote}
-%   \ttfamily
-%   |\SelectInputEncodingSet{latin1,latin9}|\\
-%   |\SelectInputMappings{|\\
-%   |  adieresis={|\EM{\"a}|}|,\\
-%   |  germandbls={|\EM{\ss}|}|,\\
-%   |}|\\
-%   \ExampleText| and Euro: |\EM{\textcurrency} (wrong)
-% \end{quote}
-% The first encoding \xoption{latin1} passes the constraints given
-% by the mapping pairs. However the Euro symbol is not part of
-% the encoding. Thus a mapping pair with the Euro symbol
-% solves the problem. In fact the symbol alone already succeeds in selecting
-% between \xoption{latin1} and \xoption{latin9}:
-% \begin{quote}
-%   \ttfamily
-%   |\SelectInputEncodingSet{latin1,latin9}|\\
-%   |\SelectInputMappings{|\\
-%   |  Euro={|\EM{\texteuro}|},|\\
-%   |}|\\
-%   \ExampleText| and Euro: |\EM{\texteuro}
-% \end{quote}
-%
-% \subsection{Options}
-%
-% \begin{description}
-% \item[\xoption{warning}:]
-%   The selected encoding is written
-%   by \cs{PackageInfo} into the \xfile{.log} file only.
-%   Option \xoption{warning} changes it to \cs{PackageWarning}.
-%   Then the selected encoding is shown on the terminal as well.
-% \item[\xoption{ucs}:]
-%   The encoding file \xfile{utf8x} of package \cs{ucs} requires
-%   that the package itself is loaded before.
-%   If the package is not loaded, then the option \xoption{ucs}
-%   will load package \xpackage{ucs} if the detected encoding is
-%   UTF-8 (limited to the preamble, packages cannot be loaded later).
-% \item[\xoption{utf8=\dots}:]
-%   The option allows to specify other encoding files
-%   for UTF-8 than \LaTeX's \xfile{utf8.def}. For example,
-%   |utf8=utf-8| will load \xfile{utf-8.def} instead.
-% \end{description}
-%
-% \subsection{Encodings}
-%
-% Package \xpackage{stringenc} \cite{stringenc}
-% is used for testing the encoding. Thus the encoding
-% name must be known by this package. Then the found
-% encoding is loaded by \cs{inputencoding} by package
-% \xpackage{inputenc} or \cs{InputEncoding} if package
-% \xpackage{inputenx} is loaded.
-%
-% The supported encodings are present in the encoding list,
-% thus usually the encoding names do not matter.
-% If the list is set by \cs{SelectInputEncodingList},
-% then you can use the names that work for package
-% \xpackage{inputenc} and are known by package \xpackage{stringenc},
-% for example: \xoption{latin1}, \xoption{x-iso-8859-1}. Encoding
-% file names of package \xpackage{inputenx} are prefixed with \xfile{x-}.
-% The prefix can be dropped, if package \xpackage{inputenx} is loaded.

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{selinput}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/selinput.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/selinput.pdf}] Documentation.
-% \end{description}
-%
-%
-% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
-% are also available in a TDS compliant ZIP archive. There
-% the packages are already unpacked and the documentation files
-% are generated. The files and directories obey the TDS standard.
-% \begin{description}
-% \item[\CTANinstall{install/macros/latex/contrib/oberdiek.tds.zip}]
-% \end{description}
-% \emph{TDS} refers to the standard ``A Directory Structure
-% for \TeX\ Files'' (\CTANpkg{tds}). Directories
-% with \xfile{texmf} in their name are usually organized this way.
-%
-% \subsection{Bundle installation}
-%
-% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
-% TDS tree (also known as \xfile{texmf} tree) of your choice.
-% Example (linux):
-% \begin{quote}
-%   |unzip oberdiek.tds.zip -d ~/texmf|
-% \end{quote}
-%
-% \subsection{Package installation}
-%
-% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
-% \docstrip\ archive. The files are extracted by running the
-% \xfile{.dtx} through \plainTeX:
-% \begin{quote}
-%   \verb|tex selinput.dtx|
-% \end{quote}
-%
-% \paragraph{TDS.} Now the different files must be moved into
-% the different directories in your installation TDS tree
-% (also known as \xfile{texmf} tree):
-% \begin{quote}

-% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
-% TDS installing feature, then some files can already be in the right
-% place, see the documentation of \docstrip.
-%
-% \subsection{Refresh file name databases}
-%
-% If your \TeX~distribution
-% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
-% these. For example, \TeX\,Live\ users run \verb|texhash| or
-% \verb|mktexlsr|.
-%
-% \subsection{Some details for the interested}
-%
-% \paragraph{Unpacking with \LaTeX.}
-% The \xfile{.dtx} chooses its action depending on the format:
-% \begin{description}
-% \item[\plainTeX:] Run \docstrip\ and extract the files.
-% \item[\LaTeX:] Generate the documentation.
-% \end{description}
-% If you insist on using \LaTeX\ for \docstrip\ (really,
-% \docstrip\ does not need \LaTeX), then inform the autodetect routine
-% about your intention:
-% \begin{quote}
-%   \verb|latex \let\install=y\input{selinput.dtx}|
-% \end{quote}
-% Do not forget to quote the argument according to the demands
-% of your shell.
-%
-% \paragraph{Generating the documentation.}
-% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
-% the documentation. The process can be configured by the
-% configuration file \xfile{ltxdoc.cfg}. For instance, put this
-% line into this file, if you want to have A4 as paper format:
-% \begin{quote}
-%   \verb|\PassOptionsToClass{a4paper}{article}|
-% \end{quote}
-% An example follows how to generate the
-% documentation with pdf\LaTeX:
-% \begin{quote}
-%\begin{verbatim}
-%pdflatex selinput.dtx
-%makeindex -s gind.ist selinput.idx
-%pdflatex selinput.dtx
-%makeindex -s gind.ist selinput.idx
-%pdflatex selinput.dtx
-%\end{verbatim}
