-% This package provides expandable arithmetic operations
-% with big integers that can exceed \TeX's number limits.

-%
-% \subsection{Introduction}
-%
-% Package \xpackage{bigintcalc} defines arithmetic operations
-% that deal with big integers. Big integers can be given
-% either as explicit integer number or as macro code
-% that expands to an explicit number. \emph{Big} means that
-% there is no limit on the size of the number. Big integers
-% may exceed \TeX's range limitation of -2147483647 and 2147483647.
-% Only memory issues will limit the usable range.
-%
-% In opposite to package \xpackage{intcalc}
-% unexpandable command tokens are not supported, even if
-% they are valid \TeX\ numbers like count registers or
-% commands created by \cs{chardef}. Nevertheless they may
-% be used, if they are prefixed by \cs{number}.
-%
-% Also \eTeX's \cs{numexpr} expressions are not supported
-% directly in the manner of package \xpackage{intcalc}.
-% However they can be given if \cs{the}\cs{numexpr}
-% or \cs{number}\cs{numexpr} are used.
-%
-% The operations have the form of macros that take one or
-% two integers as parameter and return the integer result.
-% The macro name is a three letter operation name prefixed
-% by the package name, e.g. \cs{bigintcalcAdd}|{10}{43}| returns
-% |53|.
-%
-% The macros are fully expandable, exactly two expansion
-% steps generate the result. Therefore the operations
-% may be used nearly everywhere in \TeX, even inside
-% \cs{csname}, file names, or other
-% expandable contexts.
-%
-% \subsection{Conditions}
-%
-% \subsubsection{Preconditions}
-%
-% \begin{itemize}
-% \item
-% Arguments can be anything that expands to a number that consists
-% of optional signs and digits.
-% \item
-% The arguments and return values must be sound.
-% Zero as divisor or factorials of negative numbers will cause errors.
-% \end{itemize}
-%
-% \subsubsection{Postconditions}
-%
-% Additional properties of the macros apart from calculating
-% a correct result (of course \smiley):
-% \begin{itemize}
-% \item
-% The macros are fully expandable. Thus they can
-% be used inside \cs{edef}, \cs{csname},
-% for example.
-% \item
-% Furthermore exactly two expansion steps calculate the result.
-% \item
-% The number consists of one optional minus sign and one or more
-% digits. The first digit is larger than zero for
-% numbers that consists of more than one digit.
-%
-% In short, the number format is exactly the same as
-% \cs{number} generates, but without its range limitation.
-% And the tokens (minus sign, digits)
-% have catcode 12 (other).
-% \item
-% Call by value is simulated. First the arguments are
-% converted to numbers. Then these numbers are used
-% in the calculations.
-%
-% Remember that arguments
-% may contain expensive macros or \eTeX\ expressions.
-% This strategy avoids multiple evaluations of such
-% arguments.
-% \end{itemize}
-%
-% \subsection{Error handling}
-%
-% Some errors are detected by the macros, example: division by zero.
-% In this cases an undefined control sequence is called and causes
-% a TeX error message, example: \cs{BigIntCalcError:DivisionByZero}.
-% The name of the control sequence contains
-% the reason for the error. The \TeX\ error may be ignored.
-% Then the operation returns zero as result.
-% Because the macros are supposed to work in expandible contexts.
-% An traditional error message, however, is not expandable and
-% would break these contexts.
-%
-% \subsection{Operations}
-%
-% Some definition equations below use the function $\opInt$
-% that converts a real number to an integer. The number
-% is truncated that means rounding to zero:
-% \begin{gather*}
-% \opInt(x) \Def
-% \begin{cases}
-% \lfloor x\rfloor & \text{if $x\geq0$}\\
-% \lceil x\rceil & \text{otherwise}
-% \end{cases}
-% \end{gather*}
-%
-% \subsubsection{\op{Num}}
-%
-% \begin{declcs}{bigintcalcNum} \M{x}
-% \end{declcs}
-% Macro \cs{bigintcalcNum} converts its argument to a normalized integer
-% number without unnecessary leading zeros or signs.
-% The result matches the regular expression:
-%\begin{quote}
-%\begin{verbatim}
-%0|-?[1-9][0-9]*
-%\end{verbatim}
-%\end{quote}
-%
-% \subsubsection{\op{Inv}, \op{Abs}, \op{Sgn}}
-%
-% \begin{declcs}{bigintcalcInv} \M{x}
-% \end{declcs}
-% Macro \cs{bigintcalcInv} switches the sign.
-% \begin{gather*}
-% \opInv(x) \Def -x
-% \end{gather*}
-%
-% \begin{declcs}{bigintcalcAbs} \M{x}
-% \end{declcs}
-% Macro \cs{bigintcalcAbs} returns the absolute value
-% of integer \meta{x}.
-% \begin{gather*}
-% \opAbs(x) \Def \vert x\vert
-% \end{gather*}
-%
-% \begin{declcs}{bigintcalcSgn} \M{x}
-% \end{declcs}
-% Macro \cs{bigintcalcSgn} encodes the sign of \meta{x} as number.
-% \begin{gather*}
-% \opSgn(x) \Def
-% \begin{cases}
-% -1& \text{if $x<0$}\\
-% 0& \text{if $x=0$}\\
-% 1& \text{if $x>0$}
-% \end{cases}
-% \end{gather*}
-% These return values can easily be distinguished by \cs{ifcase}:
-%\begin{quote}
-%\begin{verbatim}
-%\ifcase\bigintcalcSgn{<x>}
-% $x=0$
-%\or
-% $x>0$
-%\else
-% $x<0$
-%\fi
-%\end{verbatim}
-%\end{quote}
-%
-% \subsubsection{\op{Min}, \op{Max}, \op{Cmp}}
-%
-% \begin{declcs}{bigintcalcMin} \M{x} \M{y}
-% \end{declcs}
-% Macro \cs{bigintcalcMin} returns the smaller of the two integers.
-% \begin{gather*}
-% \opMin(x,y) \Def
-% \begin{cases}
-% x & \text{if $x<y$}\\
-% y & \text{otherwise}
-% \end{cases}

-% macros are a little more efficient.
-%
-% In general numbers must obey the following constraints:
-% \begin{itemize}
-% \item Plain number: digit tokens only, no command tokens.
-% \item Non-negative. Signs are forbidden.
-% \item Delimited by exclamation mark. Curly braces
-% around the number are not allowed and will
-% break the code.
-% \end{itemize}
-%
-% \begin{declcs}{BigIntCalcOdd} \meta{number} |!|

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{bigintcalc}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/bigintcalc.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/bigintcalc.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 bigintcalc.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}
-% \def\t{^^A

-% 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{bigintcalc.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 bigintcalc.dtx
-%makeindex -s gind.ist bigintcalc.idx
-%pdflatex bigintcalc.dtx
-%makeindex -s gind.ist bigintcalc.idx
-%pdflatex bigintcalc.dtx

-% \maketitle
-%
-% \begin{abstract}
-% New primitive commands are introduced in \eTeX. Sometimes the
-% names collide with existing macros. This package solves this
-% name clashes by adding a prefix to \eTeX's commands. For example,
-% \eTeX's \cs{unexpanded} is provided as \cs{etex@unexpanded}.
-% \end{abstract}
-%
-% \tableofcontents
-%
-% \section{Documentation}
-%
-% \subsection{\cs{unexpanded}}
-%
-% \begin{declcs}{etex@unexpanded}
-% \end{declcs}
-% New primitive commands are introduced in \eTeX. Unhappily
-% \cs{unexpanded} collides with a macro in Con\TeX t with the
-% same name. This also affects the \LaTeX\ world. For example,
-% package \xpackage{m-ch-de} loads \xfile{base/syst-gen.tex}
-% that redefines \cs{unexpanded}. Thus this package defines
-% \cs{etex@unexpanded} to get rid of the name clash.
-%
-% \begin{declcs}{ifetex@unexpanded}
-% \end{declcs}
-% Package \xpackage{etexcmds} can be loaded even if \eTeX\ is not
-% present or \cs{unexpanded} cannot be found. The switch
-% \cs{ifetex@unexpanded} tells whether it is safe to use
-% \cs{etex@unexpanded}.
-% The switch is true (\cs{iftrue}) only if the
-% primitive \cs{unexpanded} has been found and \cs{etex@unexpanded}
-% is available.
-%
-% \subsection{\cs{expanded}}
-%
-% Probably \cs{expanded} will be added in \pdfTeX\ 1.50 and
-% \LuaTeX. Again Con\TeX t defines this as macro.
-% Therefore version 1.2 of this packages also provides
-% \cs{etex@expanded} and \cs{ifetex@unexpanded}.

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{etexcmds}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/etexcmds.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/etexcmds.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 etexcmds.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}
-% \def\t{^^A

-% 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{etexcmds.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 etexcmds.dtx
-%makeindex -s gind.ist etexcmds.idx
-%pdflatex etexcmds.dtx
-%makeindex -s gind.ist etexcmds.idx
-%pdflatex etexcmds.dtx

-% \begin{abstract}
-% The \LaTeX\ package addresses packages that are dealing with
-% references to titles (\cs{section}, \cs{caption}, \dots).
-% The package tries to remove \cs{label} and other
-% commands from title strings.
-% \end{abstract}
-%
-% \tableofcontents
-%
-% \section{Documentation}
-%
-% \subsection{Macros}
-%
-% \begin{declcs}{GetTitleStringSetup} \M{key value list}
-% \end{declcs}
-% The options are given as comma separated key value pairs.
-% See section \ref{sec:options}.
-%
-% \begin{declcs}{GetTitleString} \M{text}\\
-% \cs{GetTitleStringExpand} \M{text}\\
-% \cs{GetTitleStringNonExpand} \M{text}
-% \end{declcs}
-% Macro \cs{GetTitleString} tries to remove unwanted stuff from \meta{text}
-% the result is stored in Macro \cs{GetTitleStringResult}.
-% Two methods are available:
-% \begin{description}
-% \item[\cs{GetTitleStringExpand}:]
-% The \meta{text} is expanded in a context where the unwanted
-% macros are redefined to remove themselves.
-% This is the method used in packages \xpackage{titleref}~\cite{titleref},
-% \xpackage{zref-titleref}~\cite{zref}
-% or class \xclass{memoir}~\cite{memoir}.
-% \cs{protect} is supported, but fragile material might break.
-% \item[\cs{GetTitleStringNonExpand}:]
-% The \meta{text} is not expanded. Thus the removal of unwanted
-% material is more difficult. It is especially removed at the
-% start of the \meta{text} and spaces are removed from the end.
-% Currently only \cs{label} is removed in the whole string,
-% if it is not hidden inside curly braces or part of macro
-% definitions. Thus the removal of unwanted stuff might not be
-% complete, but fragile material will not break.
-% (But the result string can break at a later time, of course).
-% \end{description}
-% Option \xoption{expand} controls which method is used by
-% macro \cs{GetTitleString}.
-%
-% \begin{declcs}{GetTitleStringDisableCommands} \M{code}
-% \end{declcs}
-% The \meta{code} is called right before the
-% text is expanded in \cs{GetTitleStringExpand}.
-% Additional definitions can be given for macros that
-% should be removed.
-% Keep in mind that expansion means that the definitions
-% must work in expandable context. Macros like
-% \cs{@ifstar} or \cs{@ifnextchar} or optional arguments
-% will not work. The macro names in \meta{code} may contain
-% the at sign |@|, it has catcode 11 (letter).

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{gettitlestring}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/gettitlestring.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/gettitlestring.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 gettitlestring.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}
-% \def\t{^^A

-% 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{gettitlestring.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 gettitlestring.dtx
-%makeindex -s gind.ist gettitlestring.idx
-%pdflatex gettitlestring.dtx
-%makeindex -s gind.ist gettitlestring.idx

-% \begin{abstract}
-% Package \xpackage{hycolor} implements the color option stuff that
-% is used by packages \xpackage{hyperref} and \xpackage{bookmark}.
-% It is not intended as package for the user.

-% \section{Documentation}
-%
-% The package \xpackage{hycolor} implements color options
-% for packages \xpackage{hyperref} and \xpackage{bookmark}.
-%
-% Package \xpackage{xcolor} provides macros for extracting
-% color values and converting color data to other color models.
-% If this package is loaded, the full range of color specifications
-% of packages \xpackage{color} and \xpackage{xcolor} are supported
-% including the optional argument for the color model.
-% \begin{quote}
-% |\hypersetup{linkbordercolor=red}%| needs \xpackage{xcolor}\\
-% |\hypersetup{linkbordercolor=[named]{red}}%| needs \xpackage{xcolor}\\
-% |\hypersetup{linkbordercolor=[rgb]{1,0,0}}|\\
-% \end{quote}
-%
-% Without package \xpackage{xcolor} some of the options only
-% support some models, if they are given directly, e.g.:
-% \begin{quote}
-% |\bookmarksetup{color=[rgb]{1,0,0}}|
-% \end{quote}
-%
-% Because of compatibility some options of \xpackage{hyperref}
-% also support space separated RGB values:
-% \begin{quote}
-% |\hypersetup{linkbordercolor=1 0 0}%| is the same as\\
-% |\hypersetup{linkbordercolor=[rgb]{1,0,0}}|
-% \end{quote}
-%
-% Coloring is optional, it can be turned off by using an empty
-% value:
-% \begin{quote}
-% |\hypersetup{linkbordercolor={}}|
-% \end{quote}
-%
-% The PDF specification knows some kind of an emtpy color setting
-% without values. This applies to form field colors. The new
-% A virtual color model \texttt{empty} is introduced for this
-% purpose, e.g.
-% \begin{quote}
-% |\TextField[backgroundcolor={[empty]{}}, ...]{...}%| or\\
-% |\TextField[{backgroundcolor=[empty]{}, ...}]{...}|
-% \end{quote}
-% PDF specification 1.7 also allows this for border link colors.
-% But this isn't currently supported by this package, because
-% the tested viewers (AR7/Linux, xpdf 3.00, ghostscript 8.54)
-% don't support this yet. In contrary ghostscript generates an
-% error message.

-% \subsection{Patch for package \xpackage{xcolor}}
-%
-% Because the test files triggered a bug in package \xpackage{xcolor}
-% of version 2007/01/21 v2.11.
-% I contacted the author of \xpackage{xcolor} Uwe Kern. He responded
-% with a test version 2007/03/27 v2.12a00 that fixes the problem.
-% However, apparently he did not found the time for an official
-% release yet. Thus I have reluctantly written the following
-% patch package using the fixes of v2.12a00.
-%
-% The patch is immediately applied if package \xpackage{xcolor}
-% is already loaded.
-% Otherwise the patch is delayed using \cs{AfterPackage} if
-% package \xpackage{scrlfile} is loaded. As last resort
-% \cs{AtBeginDocument} is used.

-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{hycolor}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/hycolor.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/hycolor.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 hycolor.dtx|
-% \end{quote}
-%
-% \paragraph{TDS.} Now the different files must be moved into
-% the different directories in your installation TDS tree

-% 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{hycolor.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 hycolor.dtx
-%makeindex -s gind.ist hycolor.idx
-%pdflatex hycolor.dtx
-%makeindex -s gind.ist hycolor.idx
-%pdflatex hycolor.dtx

-%
-% \subsection{Introduction}
-%
-% Package \xpackage{intcalc} defines arithmetic operations
-% that deal with integers. Integers mean numbers in \TeX.
-% The same restrictions apply, the range is limited to
-% [-2147483647, 2147483647].
-%
-% The operations have the form of macros that take one or
-% two integers as parameter and return the integer result.
-% The macro name is a three letter operation name prefixed
-% by the package name, e.g. \cs{intcalcAdd}|{10}{43}| returns
-% |53|.
-%
-% The macros are fully expandable, exactly two expansion
-% steps generate the result. Therefore the operations
-% may be used nearly everywhere in \TeX, even inside
-% \cs{number}, \cs{csname}, file names, or other
-% expandable contexts.
-%
-% The package contains two implementations of the operations.
-% If \eTeX\ is detected then the macros are implemented
-% using its features (\cs{numexpr}). Otherwise the slower
-% implementation without \eTeX's help is choosen.
-%
-% \subsection{Conditions}
-%
-% \subsubsection{Preconditions}
-%
-% \begin{itemize}
-% \item
-% Arguments can be anything that \TeX\ interprets as ``number''.
-% Examples: plain numbers, count or length register, macros
-% that expands to a number.
-% \item
-% The arguments are limited to the range
-% -2147483647 until 2147483647. These numbers belong to the range.
-% Note that some operations
-% have additionals restrictions to the range.
-% \item
-% The argument may be expressions that \cs{numexpr}
-% understands if \eTeX\ is available.
-% \item
-% The resulting number must fit in the allowed range.
-% \end{itemize}
-%
-% \subsubsection{Postconditions}
-%
-% Additional properties of the macros apart from calculating
-% a correct result (of course \smiley):
-% \begin{itemize}
-% \item
-% The macros are fully expandable. Thus they can
-% be used inside \cs{edef}, \cs{csname}, after \cs{number},
-% for example.
-% \item
-% Furthermore exactly two expansion steps calculate the result.
-% \item
-% The number consists of one optional minus sign and one to
-% ten digits. The first digit is larger than zero for
-% numbers that consists of more than one digit.
-%
-% In short, the number format is exactly the same as
-% \cs{number} generates. And the tokens (minus sign, digits)
-% have catcode 12 (other).
-% \item
-% Call by value is simulated. First the arguments are
-% converted to numbers. Then these numbers are used
-% in the calculations.
-%
-% Remember that arguments
-% may contain expensive macros or \eTeX\ expressions.
-% This strategy avoids multiple evaluations of such
-% arguments.
-% \end{itemize}
-%
-% \subsection{Error handling}
-%
-% There are two kinds of errors if a precondition is violated:
-% Some errors are detected by the macros, example: division by zero.
-% In this cases an undefined control sequence is called and causes
-% a TeX error message, example: \cs{IntCalcError:DivisionByZero}.
-% The name of the control sequence contains
-% the reason for the error. The \TeX\ error may be ignored.
-% Then the operation returns zero as result.
-% Because the macros are supposed to work in expandible contexts.
-% An traditional error message, however, is not expandable and
-% would break these contexts.
-%
-% If a number exceeds the range of -2147483647 until 2147483647, then
-% \TeX\ throws an error ``Number too big'' and recovers by
-% using biggest allowed value.
-% Example for the negative number -3000000000 is replaced
-% by -2147483647.
-%
-% \subsection{Operations}
-%
-% Some definition equations below use the function $\opInt$
-% that converts a real number to an integer. The number
-% is truncated that means rounding to zero:
-% \begin{gather*}
-% \opInt(x) \Def
-% \begin{cases}
-% \lfloor x\rfloor & \text{if $x\geq0$}\\
-% \lceil x\rceil & \text{otherwise}
-% \end{cases}
-% \end{gather*}
-%
-% \subsubsection{\op{Num}}
-%
-% \begin{declcs}{intcalcNum} \M{x}
-% \end{declcs}
-% Macro \cs{intcalcNum} converts its argument to a normalized integer
-% number without unnecessary leading zeros or signs.
-% The result matches the regular expression:
-%\begin{quote}
-%\begin{verbatim}
-%0|-?[1-9][0-9]*
-%\end{verbatim}
-%\end{quote}
-%
-% \subsubsection{\op{Inv}, \op{Abs}, \op{Sgn}}
-%
-% \begin{declcs}{intcalcInv} \M{x}
-% \end{declcs}
-% Macro \cs{intcalcInv} switches the sign.
-% \begin{gather*}
-% \opInv(x) \Def -x
-% \end{gather*}
-%
-% \begin{declcs}{intcalcAbs} \M{x}
-% \end{declcs}
-% Macro \cs{intcalcAbs} returns the absolute value
-% of integer \meta{x}.
-% \begin{gather*}
-% \opAbs(x) \Def \vert x\vert
-% \end{gather*}
-%
-% \begin{declcs}{intcalcSgn} \M{x}
-% \end{declcs}
-% Macro \cs{intcalcSgn} encodes the sign of \meta{x} as number.
-% \begin{gather*}
-% \opSgn(x) \Def
-% \begin{cases}
-% -1& \text{if $x<0$}\\
-% 0& \text{if $x=0$}\\
-% 1& \text{if $x>0$}
-% \end{cases}
-% \end{gather*}
-% These return values can easily be distinguished by \cs{ifcase}:
-%\begin{quote}
-%\begin{verbatim}
-%\ifcase\intcalcSgn{<x>}
-% $x=0$
-%\or
-% $x>0$
-%\else
-% $x<0$
-%\fi
-%\end{verbatim}
-%\end{quote}
-%
-% \subsubsection{\op{Min}, \op{Max}, \op{Cmp}}
-%
-% \begin{declcs}{intcalcMin} \M{x} \M{y}
-% \end{declcs}
-% Macro \cs{intcalcMin} returns the smaller of the two integers.
-% \begin{gather*}
-% \opMin(x,y) \Def
-% \begin{cases}
-% x & \text{if $x<y$}\\
-% y & \text{otherwise}
-% \end{cases}
-% \end{gather*}
-%
-% \begin{declcs}{intcalcMax} \M{x} \M{y}
-% \end{declcs}
-% Macro \cs{intcalcMax} returns the larger of the two integers.
-% \begin{gather*}
-% \opMax(x,y) \Def
-% \begin{cases}
-% x & \text{if $x>y$}\\
-% y & \text{otherwise}
-% \end{cases}
-% \end{gather*}
-%
-% \begin{declcs}{intcalcCmp} \M{x} \M{y}
-% \end{declcs}
-% Macro \cs{intcalcCmp} encodes the comparison result as number:
-% \begin{gather*}
-% \opCmp(x,y) \Def
-% \begin{cases}
-% -1 & \text{if $x<y$}\\
-% 0 & \text{if $x=y$}\\
-% 1 & \text{if $x>y$}
-% \end{cases}
-% \end{gather*}
-% These values can be distinguished by \cs{ifcase}:
-%\begin{quote}
-%\begin{verbatim}
-%\ifcase\intcalcCmp{<x>}{<y>}
-% $x=y$
-%\or
-% $x>y$
-%\else
-% $x<y$

-% \end{declcs}
-% Macro \cs{intcalcAdd} adds the two numbers.
-% \begin{gather*}
-% \opAdd(x, y) \Def x + y
-% \end{gather*}
-%
-% \begin{declcs}{intcalcSub} \M{x} \M{y}
-% \end{declcs}
-% Macro \cs{intcalcSub} calculates the difference.
-% \begin{gather*}
-% \opSub(x, y) \Def x - y
-% \end{gather*}
-%
-% \subsubsection{\op{Shl}, \op{Shr}}
-%
-% \begin{declcs}{intcalcShl} \M{x}
-% \end{declcs}
-% Macro \cs{intcalcShl} implements shifting to the left that

-% \end{gather*}
-%
-% \begin{declcs}{intcalcShr} \M{x}

-% if \meta{x} is zero and \meta{y} is negative.
-% permitted:
-% \begin{gather*}
-% \opPow(x,y) \Def
-% \opInt(x^y)\qquad\text{for $x\neq0$ or $y\geq0$}
-% \end{gather*}
-% ($0^0 = 1$)
-%
-% \subsubsection{\op{Div}, \op{Mod}}
-%
-% \begin{declcs}{intcalcDiv} \M{x} \M{y}
-% \end{declcs}
-% Macro \cs{intcalcDiv} performs an integer division.
-% Argument \meta{y} must not be zero.
-% \begin{gather*}
-% \opDiv(x,y) \Def \opInt(x/y)\qquad\text{for $y\neq0$}
-% \end{gather*}
-%
-% \begin{declcs}{intcalcMod} \M{x} \M{y}
-% \end{declcs}
-% Macro \cs{intcalcMod} gets the remainder of the integer
-% division. The sign follows the divisor \meta{y}.
-% Argument \meta{y} must not be zero.
-% \begin{gather*}
-% \opMod(x,y) \Def x\mathrel{\%}y\qquad\text{for $y\neq0$}
-% \end{gather*}
-% The result ranges:
-% \begin{gather*}
-% -\vert y\vert < \opMod(x,y) \leq 0\qquad\text{for $y<0$}\\
-% 0 \leq \opMod(x,y) < y\qquad\text{for $y\geq0$}
-% \end{gather*}

-%
-% If the programmer can ensure some more properties about
-% the arguments of the operations, then the following
-% macros are a little more efficient.
-%
-% In general numbers must obey the following constraints:
-% \begin{itemize}
-% \item Plain number: digit tokens only, no command tokens.
-% \item Non-negative. Signs are forbidden.
-% \item Arguments and the result must fit in range |0..2147483647|.
-% \item Delimited by exclamation mark. Curly braces
-% around the number are not allowed and will
-% break the code.

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{intcalc}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/intcalc.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/intcalc.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 intcalc.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}
-% \def\t{^^A

-% 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{intcalc.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 intcalc.dtx
-%makeindex -s gind.ist intcalc.idx
-%pdflatex intcalc.dtx
-%makeindex -s gind.ist intcalc.idx
-%pdflatex intcalc.dtx

-% \begin{abstract}
-% Package \xpackage{kvdefinekeys} provides \cs{kv@define@key} to define
-% keys the same way as \xpackage{keyval}'s \cs{define@key}. However, it
-% works also using \iniTeX.

-%
-% \subsection{Motivation}
-%
-% \cs{kvsetkeys} serves as replacement for \xpackage{keyval}'s
-% \cs{setkeys}. This package adds macros to define keys, closing
-% the gap \cs{kvsetkeys} leaves.
-%
-% \begin{declcs}{kv@define@key}\,\M{family}\,\M{key}\,[\meta{default}]\,^^A
-% \M{definition}
-% \end{declcs}
-% Macro \cs{kv@define@key} reimplements \xpackage{keyval}'s
-% \cs{define@key}. Differences to the original:
-% \begin{itemize}
-% \item The defined keys also allow \cs{par} inside values.
-% \item Shorthands of package \xpackage{babel} are supported in
-% family and key names.
-% \item Macro \cs{kv@define@key} is made robust if
-% \hologo{eTeX}'s \cs{protected} or \hologo{LaTeX}'s
-% \cs{DeclareRobustCommand} are found.

-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{kvdefinekeys}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/kvdefinekeys.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/kvdefinekeys.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 kvdefinekeys.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{kvdefinekeys.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 kvdefinekeys.dtx
-%makeindex -s gind.ist kvdefinekeys.idx
-%pdflatex kvdefinekeys.dtx

-% Package \xpackage{kvsetkeys} provides \cs{kvsetkeys}, a variant
-% of package \xpackage{keyval}'s \cs{setkeys}. It allows to specify
-% a handler that deals with unknown options. Active commas and equal
-% signs may be used (e.g. see \xpackage{babel}'s shorthands) and
-% only one level of curly braces is removed from the values.

-% \section{Documentation}
-%
-% First I want to recommend the very good review article
-% ``A guide to key-value methods'' by Joseph Wright \cite{tb94wright}.
-% It introduces the different key-value packages and compares them.
-%
-% \subsection{Motivation}
-%
-% \cs{kvsetkeys} serves as replacement for \xpackage{keyval}'s
-% \cs{setkeys}. It basically uses the same syntax. But the
-% implementation is more robust and predictable:
-% \begin{description}
-% \item[Active syntax characters:]
-% Comma `|,|' and the equals sign `|=|' are used inside
-% key value lists as syntax characters. Package \xpackage{keyval}
-% uses the catcode of the characters that is active during
-% package loading, usually this is catcode 12 (other).
-% But it can happen that the catcode setting of the syntax characters
-% changes. Especially active characters are of interest, because
-% some language adaptations uses them. For example, option \xoption{turkish}
-% of package \xpackage{babel} uses the equals sign as active shorthand
-% character. Therefore package \xpackage{kvsetkeys} deals with
-% both catcode settings 12 (other) and 13 (active).
-% \item[Brace removal:]
-% Package \xpackage{keyval}'s \cs{setkeys} removes up to two
-% levels of curly braces around the value in some unpredictable way:
-%\begin{quote}
-%|\setkeys{fam}{key={{value}}} || || | $\rightarrow$ |value|\\
-%|\setkeys{fam}{key={{{value}}}} | $\rightarrow$ |{value}|\\
-%|\setkeys{fam}{key= {{{value}}}}| $\rightarrow$ |{{value}}|
-%\end{quote}
-% This package \xpackage{kvsetkeys} follows a much stronger rule:
-% Exactly one level of braces are removed from an item, if the
-% item is surrounded by curly braces. An item can be a
-% the key value pair, the key or the value.
-%\begin{quote}
-%|\kvsetkeys{fam}{key={value}} || | $\rightarrow$ |value|\\
-%|\kvsetkeys{fam}{key={{value}} | $\rightarrow$ |{value}|\\
-%|\kvsetkeys{fam}{key= {{value}}| $\rightarrow$ |{value}|
-%\end{quote}
-% \item[Arbitrary values:] Unmatched conditionals are supported.
-% \end{description}
-%
-% Before I describe
-% \cs{kvsetkeys} in more detail, first I want to explain, how
-% this package deals with key value lists. For the package also
-% provides low level interfaces that can be used by package authors.
-%
-% \subsection{Normalizing key value lists}
-%
-% \begin{declcs}{kv@normalize}\,\M{key value list}
-% \end{declcs}
-% If the user specifies key value lists, he usually prefers
-% nice formatted source code, e.g.:
-% \begin{quote}
-%\begin{verbatim}
-%\hypersetup{
-% pdftitle = {...},
-% pdfsubject = {...},
-% pdfauthor = {...},
-% pdfkeywords = {...},
-% ...
-%}
-%\end{verbatim}
-% \end{quote}
-% Thus there can be spaces around keys, around |=| or around the value.
-% Also empty entries are possible by too many commas. Therefore these
-% spaces and empty entries are silently removed by package \xpackage{keyval}
-% and this package. Whereas the contents of the value can be protected
-% by curly braces, especially if spaces or commas are used inside,
-% a key name must not use spaces or other syntax characters.
-%
-% \cs{kv@normalize} takes a key value list and performs the cleanup:
-% \begin{itemize}
-% \item Spaces are removed.
-% \item Syntax characters (comma and equal sign) that are active
-% are replaced by the same characters with standard catcode.
-% (Example: \xpackage{babel}'s language option \xoption{turkish}
-% uses the equal sign as active shorthand character.)
-% \end{itemize}
-% The result is stored in \cs{kv@list}, e.g.:
-% \begin{quote}
-% |\kv@list| $\rightarrow$ |,pdftitle={...},pdfsubject={...},...,|
-% \end{quote}
-% Curly braces around values (or keys) remain untouched.
-% \begin{description}
-% \item[v1.3+:]
-% One comma is added in front of the list and each pair ends with
-% a comma. Thus an empty list consists of one comma, otherwise
-% two commas encloses the list. Empty entries other than the first
-% are removed.
-% \item[v1.0 -- v1.2:]
-% Empty entries are removed later. In fact it adds a comma at the begin
-% and end to protect the last value and an easier implementation.
-% \end{description}
-%
-% \subsection{Parsing key value lists}
-%
-% \begin{declcs}{kv@parse}\,\M{key value list}\,\M{processor}
-% \end{declcs}
-% It is easier to parse a normalized list, thus \cs{kv@parse}
-% normalizes the list and calls \cs{kv@parse@normalized}.
-%
-% \begin{declcs}{kv@parse@normalized}\,\M{key value list}%
-% \,\M{processor}
-% \end{declcs}
-% Now the key value list is split into single key value pairs.
-% For further processing the key and value are given as arguments
-% for the \meta{processor}:
-% \begin{quote}
-% \meta{processor}\,\M{key}\,\M{value}
-% \end{quote}
-% Also key and value are stored in macro names:
-% \begin{itemize}
-% \item \cs{kv@key} stores the key.
-% \item \cs{kv@value} stores the value or if the value was not
-% specified it has the meaning \cs{relax}.
-% \end{itemize}
-% The behaviour in pseudo code:
-% \begin{quote}
-% foreach (\meta{key}, \meta{value}) in (\meta{key value list})\\
-% \hspace*{1.5em}\cs{kv@key} := \meta{key}\\
-% \hspace*{1.5em}\cs{kv@value} := \meta{value}\\
-% \hspace*{1.5em}\meta{processor}\,\M{key}\,\M{value}
-% \end{quote}
-%
-% \begin{declcs}{kv@break}
-% \end{declcs}
-% Since version 2011/03/03 v1.11 \cs{kv@break} can be
-% called inside the \meta{processor}
-% of \cs{kv@parse} or \cs{kv@parse@normalized}, then
-% the processing is stopped and the following entries discarded.
-%
-% \subsection{Processing key value pairs}

-% Key value pairs can be processed in many different ways.
-% For example, the processor for \cs{kvsetkeys} works similar
-% to \cs{setkeys} of package \xpackage{keyval}. There unknown
-% keys raise an error.
-%
-% Package \xpackage{xkeyval} also knows a star form of \cs{setkeys}
-% that stores unknown keys in an internal macro for further processing
-% with \cs{setrmkeys} and similar macros. This feature is covered
-% by processor \cs{kv@processor@known}.
-%
-% \subsubsection{Processing similar to \xpackage{keyval}}
-%
-% \begin{declcs}{kv@processor@default}\,\M{family}\,\M{key}\,\M{value}
-% \end{declcs}
-% There are many possiblities to process key value pairs.
-% \cs{kv@processor@default} is the processor used in \cs{kvsetkeys}.
-% It reimplements and extends the behaviour of
-% \xpackage{keyval}'s \cs{setkeys}.
-% In case of unknown keys \cs{setkeys} raise an error.
-% This processer, however, calls a handler instead, if it
-% is provided by the family. Both \meta{family} and \meta{key}
-% may contain package \xpackage{babel}'s shorthands
-% (since 2011/04/07 v1.13).
-%
-% Since 2011/10/18 v1.15 the family handler can reject the
-% successful handling of a key by calling \cs{kv@handled@false}.
-%
-% Since 2016/05/16 v1.17 \cs{kv@processor@default} also defines
-% macro \cs{kv@fam} with meaning \meta{family} for convenience.
-%
-% \subsubsection{Processing similar to \cs{setkeys*} of package \xpackage{xkeyval}}
-%
-% \begin{declcs}{kv@processor@known}\,\M{family}\,^^A
-% \M{cmd}\,\M{key}\,\M{value}
-% \end{declcs}
-% The key value processor \cs{kv@processor@known} behaves similar
-% to \cs{kv@processor@default}. If the \meta{key} exists in the
-% \meta{family} its code is called, otherwise the family handler
-% is tried. If the family handler is not set or cannot handle the
-% key, the unknown key value pair is added to the macro \meta{cmd}.
-% Since 2011/10/18 v1.15.
-%
-% The behaviour in pseudo code:
-% \begin{quote}
-% if \meta{key} exists\\
-% \hspace*{1.5em}call the keyval code of \meta{key}\\
-% else\\
-% \hspace*{1.5em}if \meta{handler} for \meta{family} exists\\
-% \hspace*{3em}handled = true\\
-% \hspace*{3em}\meta{handler}\,\M{key}\,\M{value}\\
-% \hspace*{3em}if handled\\
-% \hspace*{3em}else\\
-% \hspace*{4.5em}add \texttt{"}\M{key}\texttt{=}\M{value}\texttt{"}
-% to \M{cmd}\\
-% \hspace*{3em}fi\\
-% \hspace*{1.5em}else\\
-% \hspace*{3em}add \texttt{"}\M{key}\texttt{=}\M{value}\texttt{"}
-% to \M{cmd}\\
-% \hspace*{3em}raise unknown key error\\
-% \hspace*{1.5em}fi\\
-% fi
-% \end{quote}
-%
-% Since 2016/05/16 v1.17 \cs{kv@processor@known} also defines
-% macro \cs{kv@fam} with meaning \meta{family} for convenience.
-%
-% \subsection{Default family handler}
-%
-% \cs{kv@processor@default} calls \meta{handler}, the default
-% handler for the family, if the key does not exist in the family.
-% The handler is called with two arguments, the key and the value.
-% It can be defined with \cs{kv@set@family@hander}:
-%
-% \begin{declcs}{kv@set@family@handler}\,\M{family}\,\M{handler definition}
-% \end{declcs}
-% This sets the default family handler for the keyval family
-% \meta{family}. Inside \meta{handler definition} |#1| stands for
-% the key and |#2| is the value. Also \cs{kv@key} and \cs{kv@value}
-% can be used for the key and the value. If the value is not given,
-% \cs{kv@value} has the meaning \cs{relax}.
-%
-% \begin{declcs}{kv@unset@family@handler}\,\M{family}
-% \end{declcs}
-% It removes the family handler for \meta{family}.
-% Since 2011/10/18 v1.15.
-%
-% \subsection{Put it all together}
-%
-% \begin{declcs}{kvsetkeys}\,\M{family}\,\M{key value list}
-% \end{declcs}
-% Macro \cs{kvsetkeys} processes the \meta{key value list} with
-% the standard processor \cs{kv@processor@default}:
-% \begin{quote}
-% \cs{kv@parse}\,\M{key value list}^^A
-% \texttt{\{}\cs{kv@processor@default}\,\M{family}\texttt{\}}
-% \end{quote}
-%
-% \begin{declcs}{kvsetknownkeys}\,\M{family}\,\M{cmd}\,\M{key value list}
-% \end{declcs}
-% Macro \cs{kvsetknownkeys} processes the \meta{key value list}
-% with processor \cs{kv@processor@known}. All key value pairs
-% with keys that are not known in \meta{family} are stored
-% in macro \meta{cmd}. A previous contents of macro \meta{cmd}
-% will be overwritten. If all keys can be handled, \meta{cmd}
-% will be empty, otherwise it contains a key value list of
-% unhandled key value pairs.
-% Since 2011/10/18 v1.15.
-%
-% Pseudo code:
-% \begin{quote}
-% create macro \meta{cmdaux} with unique name (inside the current group)\\
-% \cs{def}\meta{cmdaux}\{\}\\
-% \cs{kv@parse}\,\M{key value list}^^A
-% \texttt{\{}\cs{kv@processor@known}\,\M{family}\,\M{cmdaux}\texttt{\}}\\
-% \cs{let}\meta{cmd}=\meta{cmdaux}
-% \end{quote}
-%
-% \begin{declcs}{kvsetkeys@expandafter}\,\M{family}\,\M{list cmd}\\
-% \cs{kvsetknownkeys@expandafter}\,\M{family}\,%
-% \M{cmd}\,\M{list cmd}
-% \end{declcs}
-% Both macros behave like the counterparts without suffix
-% |@expandafter|. The difference is that the key value list is
-% given as macro that is expanded once.
-% Since 2011/10/18 v1.15.
-%
-% Thus you can replace \cs{setkeys} of package \xpackage{keyval}
-% by the key value parser of this package:
-% \begin{quote}
-% |\renewcommand*{\setkeys}{\kvsetkeys}|\\
-% or\\
-% |\let\setkeys\kvsetkeys|
-% \end{quote}
-%
-% \subsection{Comma separated lists}
-%
-% Since version 2007/09/29 v1.3 this package also supports the normalizing
-% and parsing of general comma separated lists.
-%
-% \begin{declcs}{comma@normalize}\,\M{comma list}
-% \end{declcs}
-% Macro \cs{comma@normalize} normalizes the comma separated list,
-% removes spaces around commas. The result is put in macro \cs{comma@list}.
-%
-% \begin{declcs}{comma@parse}\,\M{comma list}\,\M{processor}
-% \end{declcs}
-% Macro \cs{comma@parse} first normalizes the comma separated list
-% and then parses the list by calling \cs{comma@parse@normalized}.
-%
-% \begin{declcs}{comma@parse@normalized}\,\M{normalized comma list}^^A
-% \,\M{processor}
-% \end{declcs}
-% The list is parsed. Empty entries are ignored. \meta{processor}
-% is called for each non-empty entry with the entry as argument:
-% \begin{quote}
-% \meta{processor}|{|\meta{entry}|}|
-% \end{quote}
-% Also the entry is stored in the macro \cs{comma@entry}.
-%
-% \begin{declcs}{comma@break}
-% \end{declcs}
-% Since version 2011/03/03 v1.11 \cs{comma@break} can be
-% called inside the \meta{processor}
-% of \cs{comma@parse} or \cs{comma@parse@normalized}, then
-% the processing is stopped and the following entries discarded.
-%
-% \section{Example}
-%
-% The following example prints a short piece of HTML code using
-% the tabbing environment for indenting purpose and a key value
-% syntax for specifying the attributes of an HTML tag.
-% The example illustrates the use of a default family handler.

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{kvsetkeys}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/kvsetkeys.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/kvsetkeys.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 kvsetkeys.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{kvsetkeys.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 kvsetkeys.dtx
-%makeindex -s gind.ist kvsetkeys.idx
-%pdflatex kvsetkeys.dtx
-%makeindex -s gind.ist kvsetkeys.idx

-% \section{Documentation}
-%
-% \subsection{Introduction}
-%
-% Many of my packages also support other formats such as plain-\TeX.
-% Because I am rather familiar with the utility macros from
-% \LaTeX's kernel (e.g. \cs{@gobble}, \cs{@firstoftwo}), I found
-% myself rewriting them again and again, because they are lacking
-% in plain-\TeX.
-%
-% Therefore this package provides often used macros and similar
-% ones with the name prefix \cs{ltx@}. This avoids also faulty
-% redefinitions. I remember an example where a package redefined
-% \cs{@firstoftwo} with forgetting \cs{long}.
-%
-% \subsection{Numbers}
-%
-% \begin{declcs}{ltx@zero} \TO 0\\
-% \cs{ltx@one} \TO 1\\
-% \cs{ltx@two} \TO 2\\
-% \cs{ltx@cclv} \TO 255\\
-% \cs{ltx@minusone} \TO -1
-% \end{declcs}
-% These commands are numbers 0, 1, 2, 255 and -1. They are not digits
-% and a space is not gobbled afterwards. Macro \cs{ltx@minusone}
-% is available since version 2010/12/12 v1.15.
-%
-% \subsection{Scratch registers}
-%
-% Following the conventions of \hologo{plainTeX} and \hologo{LaTeX}
-% the first ten registers are free to use. Even numbered registers
-% are for local, odd numbered for global use.
-%
-% \begin{declcs}{ltx@(Loc,Glob)(Toks,Dimen,Skip)(A,B,C,D,E)}
-% \end{declcs}
-% The name consists of the prefix \cs{ltx@}, then
-% \texttt{Loc} or \texttt{Glob} for local or global usage follows.
-% The register type is given by \texttt{Toks} for token register,
-% \texttt{Dimen} for dimen register and \texttt{Skip} for skip
-% register. As last part the registers are numbered from \texttt{A}
-% to \texttt{E}. Example: \cs{ltx@LocToksA}.
-%
-% Since 2011/04/14 v1.19.
-%
-% \subsection{Argument killers}
-%
-% \begin{declcs}{ltx@gobble} \M{1} \TO\\
-% \cs{ltx@gobbletwo} \M{1} \M{2} \TO\\
-% \cs{ltx@gobblethree} \M{1} \M{2} \M{3} \TO\\
-% \cs{ltx@gobblefour} \M{1} \M{2} \M{3} \M{4} \TO
-% \end{declcs}
-%
-% \begin{declcs}{ltx@GobbleNum} \M{num} \M{1} \M{2} \dots\space
-% \M{\meta{num}} \TO
-% \end{declcs}
-% The first argument \meta{num} of macro \cs{ltx@GobbleNum} specifies,
-% how many following arguments are eaten. Macro \cs{ltx@GobbleNum}
-% is expandable in exact two expansion steps.
-%
-% \subsection{Argument grabbers}
-%
-% \begin{declcs}{ltx@firstofone} \M{1} \TO \meta{1}\\[1ex]
-% \cs{ltx@firstoftwo} \M{1} \M{2} \TO \meta{1}\\
-% \cs{ltx@secondoftwo} \M{1} \M{2} \TO \meta{2}\\[1ex]
-% \cs{ltx@firstofthree} \M{1} \M{2} \M{3} \TO \meta{1}\\
-% \cs{ltx@secondofthree} \M{1} \M{2} \M{3} \TO \meta{2}\\
-% \cs{ltx@thirdofthree} \M{1} \M{2} \M{3} \TO \meta{3}\\
-% \cs{ltx@firstoffour} \M{1} \M{2} \M{3} \M{4} \TO \meta{1}\\
-% \cs{ltx@secondoffour} \M{1} \M{2} \M{3} \M{4} \TO \meta{2}\\
-% \cs{ltx@thirdoffour} \M{1} \M{2} \M{3} \M{4} \TO \meta{3}\\
-% \cs{ltx@fourthoffour} \M{1} \M{2} \M{3} \M{4} \TO \meta{4}
-% \end{declcs}
-% Macros \cs{ltx@firstofthree}, \cs{ltx@secondofthree}
-% and \cs{ltx@thirdofthree} were added in version
-% 2010/11/12 v1.11.
-% Macros \cs{ltx@firstoffour}, \dots, \cs{ltx@fourthoffour}
-% were added in version 2011/02/04 v1.16.

-%
-% Macros with uppercase letters are expandable in two expansion steps.
-% Changes in version 2016/05/16 v1.23:
-% \begin{itemize}
-% \item
-% Macros \cs{ltx@carsecond}, \cs{ltx@carthird}, \cs{ltx@carfourth},
-% \cs{ltx@CarNumth} added.
-% \item
-% Macros \cs{ltx@cdr}, \cs{ltx@cdrtwo}, \cs{ltx@cdrthree}, \cs{ltx@cdrfour},
-% \cs{ltx@CdrNum} are expandable in two expansion steps and retain
-% spaces and braces after the first gobbled arguments.
-% \end{itemize}
-%
-% \subsection{Tail recursion}
-%
-% \begin{declcs}{ltx@ReturnAfterFi} \M{1} \cs{fi} \TO \cs{fi} \meta{1}\\
-% \cs{ltx@ReturnAfterElseFi} \M{1} \cs{else} \M{2} \cs{fi}
-% \TO \cs{fi} \meta{1}
-% \end{declcs}
-%
-% \subsection{Empty macro}
-%
-% \begin{declcs}{ltx@empty} \TO
-% \end{declcs}
-%
-% \subsection{Characters}
-%
-% \begin{declcs}{ltx@space} \TO \verb*| |\\
-% \cs{ltx@percentchar} \TO \texttt{\%}\\
-% \cs{ltx@backslashchar} \TO
-% \makeatletter\texttt{\@backslashchar}\\
-% \cs{ltx@hashchar} \TO \texttt{\#}\qquad(since v1.7)\\
-% \cs{ltx@leftbracechar} \TO \texttt{\textbraceleft}\qquad(since v1.8)\\
-% \cs{ltx@rightbracechar} \TO \texttt{\textbraceright}\qquad(since v1.8)
-% \end{declcs}
-%
-% \subsection{Boolean switch}
-%
-% \begin{declcs}{ltx@newif} \M{cmd}
-% \end{declcs}
-% \cs{ltx@newif} defines a new boolean switch \meta{cmd} like \cs{newif}.
-% Unlike \plainTeX's \cs{newif}, \cs{ltx@newif} is not \cs{outer}.
-% The command \meta{cmd} must start with the two characters |if|.
-%
-% \begin{declcs}{ltx@newglobalif} \M{cmd}
-% \end{declcs}
-% \cs{ltx@newglobalif} defines a new boolean switch \meta{cmd}
-% like \cs{ltx@newif}. However the switch setting commands,
-% \meta{cmd} without the prefix |if| and followed by |true| or |false|
-% are acting globally.
-%
-% \subsection{Command definitions}
-%
-% \begin{declcs}{ltx@ifundefined} \M{cmd} \M{yes} \M{no}
-% \end{declcs}
-% If \eTeX\ is available, \cs{ifcsname} is used that does
-% not have the side effect of defining undefined commands
-% with meaning of \cs{relax}. This command is always expandable.
-% Change in version 1.1: Also the meaning \cs{relax} is
-% always considered ``undefined''.
-%
-% \begin{declcs}{ltx@IfUndefined} \M{cmd} \M{yes} \M{no}
-% \end{declcs}
-% If \eTeX\ is available, \cs{ifcsname} is used that does
-% not have the side effect of defining undefined commands
-% with meaning of \cs{relax}. Also it always checks for
-% the meaning of \cs{relax} and considers this as undefined.
-% This macro is not expandable without \eTeX.
-%
-% \begin{declcs}{ltx@LocalExpandAfter}
-% \end{declcs}
-% It expands the token after the next token but in a local
-% context. That is the difference to \cs{expandafter}.
-% The local context discards the side effect of \cs{csname}
-% and let the command undefined after the expansion step.
-%
-% \subsection{Stripping}
-%
-% \begin{declcs}{ltx@RemovePrefix}\\
-% \cs{ltx@StripPrefix}
-% \end{declcs}
-% All tokens up to and including the next available character
-% `\textgreater' are thrown away. Usually it is used to strip
-% the first part of the output of the commands \cs{meaning}
-% or \cs{pdflastmatch}. Macro \cs{ltx@RemovePrefix}
-% has the same meaning as \LaTeX's \cs{strip@prefix}, whereas
-% macro \cs{ltx@StripPrefix} expands the next token
-% once before stripping the prefix.
-%
-% \begin{declcs}{ltx@onelevel@sanitize} \M{macro}
-% \end{declcs}
-% Macro \cs{ltx@onelevel@sanitize} provides \hologo{LaTeX}'s
-% \cs{@onelevel@sanitize}. The macro is expanded once and
-% the contents is converted to characters with catcode 12 (other)
-% and space tokens with catcode 10 (space). Then then sanitized
-% contents is stored into the macro again. Since version 1.12.
-%
-% \subsection{File management}
-%
-% All macros in this section are expandable like
-% the counterparts of the \LaTeX\ kernel. Also they
-% can be used after the preamble.
-%
-% \subsubsection{File extensions}
-%
-% \begin{declcs}{ltx@clsextension}\\
-% \cs{ltx@pkgextension}
-% \end{declcs}
-% Macros \cs{ltx@clsextension} and \cs{ltx@styextension}
-% stores the strings |cls| and |sty|. In opposite to \hologo{LaTeX}'s
-% \cs{@clsextension} and \cs{@styextension} they can also be
-% used after |\begin{document}|.
-%
-% \subsubsection{Load check}
-%
-% \begin{declcs}{ltx@ifclassloaded} \M{class} \M{yes} \M{no}\\
-% \cs{ltx@ifpackageloaded} \M{package} \M{yes} \M{no}
-% \end{declcs}
-% Macros \cs{ltx@ifclassloaded}\slash\cs{ltx@ifpackageloaded}
-% execute \meta{yes}, if the \meta{class} or \meta{package} is loaded,
-% otherwise \meta{no} is called.
-% Both \meta{class} and \meta{package} are specified without
-% extension. The macros can also be used after |\begin{document}|.
-%
-% \begin{declcs}{ltx@iffileloaded} \M{file} \M{yes} \M{no}
-% \end{declcs}
-% If \LaTeX's \cs{ProvidesFile} macro was called before
-% using \meta{file} as argument, then \cs{ltx@iffileloaded}
-% calls \meta{yes}, otherwise \meta{no}.
-% Therefore it is possible
-% that the \meta{file} is loaded, but \meta{no} is executed because
-% of a missing \cs{ProvidesFile}. The \LaTeX\ kernel does not have
-% a counterpart of \cs{ltx@iffileloaded}.
-%
-% Note that the file name used in \cs{ProvidesFile} and
-% \cs{ltx@iffileloaded} must match. For example, if \TeX's
-% default extension \xext{tex} was given in the first command,
-% then it must also specified in the latter command and vice versa.
-%
-% \subsubsection{Version date check}
-%
-% \begin{declcs}{ltx@ifclasslater} \M{class} \M{date} \M{yes} \M{no}\\
-% \cs{ltx@ifpackagelater} \M{package} \M{date} \M{yes} \M{no}\\
-% \cs{ltx@iffilelater} \M{file} \M{date} \M{yes} \M{no}
-% \end{declcs}
-% If a \cs{ProvidesClass}\slash\cs{ProvidesPackage}\slash
-% \cs{ProvidesFile} command with exact the same class\slash package\slash
-% file was executed before with an optional
-% argument that starts with a \LaTeX\ version date, then
-% this version date is compared with the argument \meta{date}.
-% If they are equal or if the version date is the later date,
-% then \meta{yes} is called. In all other cases \meta{no} is executed.
-%
-% A \LaTeX\ date has the format |YYYY/MM/DD| with |YYYY| as year
-% with four digits, |MM| as month with two digits and |DD| as day
-% with two digits. If \pdfTeX's \cs{pdfmatch} is available, then
-% it is used to detect the version date, to reject invalid
-% date formats and to reject some invalid dates.
-% Dates before 1994/01/01 are always invalid, because version
-% dates are introduced with \LaTeXe\ in 1994.
-%
-% \subsection{Macro additions}
-%
-% \begin{declcs}{ltx@GlobalAppendToMacro} \M{cmd} \M{addition}\\
-% \cs{ltx@LocalAppendToMacro} \M{cmd} \M{addition}
-% \end{declcs}
-% The \meta{addition} is appended to the parameterless macro \meta{cmd}.
-% If \meta{cmd} is undefined or has the meaning \cs{relax}, then
-% it will be initialized as empty macro beforehand. Due to a bug \meta{addition}
-% must not contain \cs{par} before version 2010/10/25 v1.9.
-%
-% \begin{declcs}{ltx@GlobalPrependToMacro} \M{cmd} \M{addition}\\
-% \cs{ltx@LocalPrependToMacro} \M{cmd} \M{addition}
-% \end{declcs}
-% The \meta{addition} is prepended to the parameterless macro \meta{cmd}.
-% If \meta{cmd} is undefined or has the meaning \cs{relax}, then
-% it will be initialized as empty macro beforehand. The macros
-% were added in version 2011/08/22 v1.21.
-%
-% \subsection{Next character detection}
-%
-% \begin{declcs}{ltx@ifnextchar} \M{char} \M{yes} \M{no}
-% \end{declcs}
-% If next character is \meta{char} then \meta{yes} is called,
-% otherwise \meta{no}. The character is not removed.
-% Spaces are silently removed when looking for \meta{char}
-% as \hologo{LaTeX}'s version \cs{kernel@ifnextchar} does.
-% But there are also small differences:
-% \begin{itemize}
-% \item The space can be used as \meta{char}. In this case
-% optional spaces before \meta{char} are not supported of course.
-% \item If the optional space is a command that is a character
-% (defined by \cs{let} or \cs{futurelet}), then
-% \cs{kernel@ifnextchar} breaks with an \hologo{TeX} error.
-% \cs{ltx@ifnextchar} silently removes this token as
-% optional space.
-% \end{itemize}
-% Since 2010/03/01 v1.3.
-%
-% \begin{declcs}{ltx@ifnextchar@nospace} \M{char} \M{yes} \M{no}
-% \end{declcs}
-% Macro \cs{ltx@ifnextchar@nospace} behaves like
-% macro \cs{ltx@ifnextchar} with the exception that
-% optional spaces are not supported before \meta{char}.
-% Since 2011/04/14 v1.19.
-%
-% \subsection{\cs{ltx@leavevmode}, \cs{ltx@mbox}}
-%
-% \begin{declcs}{ltx@leavevmode}
-% \end{declcs}
-% Macro \cs{ltx@leavevmode} calls \hologo{pdfTeX}'s \cs{quitvmode}.
-% Otherwise \cs{leavevmode} is used and defined if it is necessary.
-%
-% \begin{declcs}{ltx@mbox}
-% \end{declcs}
-% Macro \cs{ltx@mbox} reimplements \cs{mbox} with two changes.
-% Instead of \cs{leavevmode} it uses \cs{ltx@leavevmode} and
-% stops right after \cs{hbox}. Especially it does not grab
-% the argument and allows the extended syntax of \cs{hbox}.
-%
-% \subsection{Expandable test for emptiness}
-%
-% \begin{declcs}{ltx@ifempty} \M{stuff} \M{yes} \M{no}
-% \end{declcs}
-% Macro \cs{ltx@ifempty} checks in exact two expansion steps
-% whether \meta{stuff}
-% is empty or contains token. Depending on the result
-% \meta{yes} or \meta{no} is executed. The token in \meta{stuff}
-% may contain \cs{par} and unmatched conditionals (\cs{if}, \cs{else},
-% \cs{fi}, \dots). Since version 2010/11/12 v1.11.
-%
-% \begin{declcs}{ltx@ifblank} \M{stuff} \M{yes} \M{no}
-% \end{declcs}
-% Macro \cs{ltx@ifblank} tests in exact two expansion steps
-% if \meta{stuff} is empty or contain only blank spaces.
-% In this case argument \meta{yes} is called. If \meta{stuff}
-% contains other tokens than spaces then \meta{no} is executed.
-% Since version 2010/12/04 v1.13.
-%
-% \subsection{Stripping spaces}
-%
-% \begin{declcs}{ltx@zapspace} \M{stuff}
-% \end{declcs}
-% Macro \cs{ltx@zapspace} strips spaces from \meta{stuff}
-% that are not hidden inside curly braces. Like \hologo{LaTeX}'s
-% \cs{zap@space} it is expandable. Differences:
-% \begin{itemize}
-% \item
-% Syntax: \cs{zap@space} also expects a space token
-% and \cs{@empty} after \meta{stuff}.
-% \item
-% Macro \cs{ltx@zapspace} is expandable in exact two
-% expansion steps.
-% \item
-% Macro \cs{ltx@zapspace} always retains curly braces.
-% \item
-% Macro \cs{zap@space} has a bug. It stops stripping spaces
-% after a token group in curly braces if the first two tokens
-% inside the group are equal.
-% \item
-% Macro \cs{ltx@zapspace} also works with \cs{par}
-% and conditionals (\cs{if}, \cs{else}, \cs{fi}, \dots).
-% \end{itemize}
-% Macro \cs{ltx@zapspace} is available since version
-% 2010/12/07 v1.14.

-% \subsection{Check for emptiness of boxes}
-%
-% \begin{declcs}{ltx@IfBoxEmpty} \M{box register number}
-% \M{yes} \M{no}
-% \end{declcs}
-% Macro \cs{ltx@IfBoxEmpty} calls \meta{yes} if
-% the box exists (\cs{ifvoid} returns false) and the box
-% does not contain any content. Otherwise if the box
-% is void or contains something, then \meta{no} is executed.
-% Thus being empty means that the box exists and is either
-% an \cs{hbox} or a \cs{vbox} and may even have dimensions other than
-% 0.0\,pt, but the box does not contain anything.
-% Macro \cs{ltx@IfBoxEmpty} is available since 2010/02/04 v1.16.
-%
-% \begin{declcs}{ltx@IfBoxVoidOrEmpty} \M{box register number}
-% \M{yes} \M{no}
-% \end{declcs}
-% Macro \cs{ltx@IfBoxVoidOrEmpty} calls \meta{yes} if
-% the box is either void or does not contain any content.
-% Otherwise \meta{no} is executed.
-% Macro \cs{ltx@IfBoxVoidOrEmpty} is available since 2010/02/04 v1.16.

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{ltxcmds}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/ltxcmds.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/ltxcmds.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 ltxcmds.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{ltxcmds.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 ltxcmds.dtx
-%makeindex -s gind.ist ltxcmds.idx
-%pdflatex ltxcmds.dtx
-%makeindex -s gind.ist ltxcmds.idx
-%pdflatex ltxcmds.dtx
-%\end{verbatim}

-% References are not numbers, however they often store numerical
-% data such as section or page numbers. \cs{ref} or \cs{pageref}
-% cannot be used for counter assignments or calculations because

-% \section{Usage}
-%
-% \subsection{Setting counters}
-%
-% The following commands are similar to \LaTeX's
-% \cs{setcounter} and \cs{addtocounter},
-% but they extract the number value from a reference:
-% \begin{quote}
-% \cs{setcounterref}, \cs{addtocounterref}\\
-% \cs{setcounterpageref}, \cs{addtocounterpageref}
-% \end{quote}
-% They take two arguments:
-% \begin{quote}
-% \cs{...counter...ref} |{|\meta{\LaTeX\ counter}|}|
-% |{|\meta{reference}|}|
-% \end{quote}
-% An undefined references produces the usual LaTeX warning
-% and its value is assumed to be zero.
-% Example:
-% \begin{quote}
-%\begin{verbatim}
-%\newcounter{ctrA}
-%\newcounter{ctrB}
-%\refstepcounter{ctrA}\label{ref:A}
-%\setcounterref{ctrB}{ref:A}
-%\addtocounterpageref{ctrB}{ref:A}
-%\end{verbatim}
-% \end{quote}
-%
-% \subsection{Expandable commands}
-%
-% These commands that can be used in expandible contexts
-% (inside calculations, \cs{edef}, \cs{csname}, \cs{write}, \dots):
-% \begin{quote}
-% \cs{getrefnumber}, \cs{getpagerefnumber}
-% \end{quote}
-% They take one argument, the reference:
-% \begin{quote}
-% \cs{get...refnumber} |{|\meta{reference}|}|
-% \end{quote}
-% The default for undefined references can be changed
-% with macro \cs{setrefcountdefault}, for example this
-% package calls:
-% \begin{quote}
-% \cs{setrefcountdefault}|{0}|
-% \end{quote}
-%
-% Since version 2.0 of this package there is a new
-% command:
-% \begin{quote}
-% \cs{getrefbykeydefault} |{|\meta{reference}|}|
-% |{|\meta{key}|}| |{|\meta{default}|}|
-% \end{quote}
-% This generalized version allows the extraction
-% of further properties of a reference than the
-% two standard ones. Thus the following properties
-% are supported, if they are available:
-% \begin{quote}
-% \begin{tabular}{@{}l|l|l@{}}
-% Key & Description & Package\\
-% \hline

-% Since version 3.2 the expandable macros described before
-% in this section
-% are expandable in exact two expansion steps.
-%
-% \subsection{Undefined references}
-%
-% Because warnings and assignments cannot be used in
-% expandible contexts, undefined references do not
-% produce a warning, their values are assumed to be zero.
-% Example:
-% \begin{quote}
-%\begin{verbatim}
-%\label{ref:here}% somewhere
-%\refused{ref:here}% see below
-%\ifodd\getpagerefnumber{ref:here}%
-% reference is on an odd page
-%\else
-% reference is on an even page
-%\fi
-%\end{verbatim}
-% \end{quote}
-%
-% In case of undefined references the user usually want's
-% to be informed. Also \LaTeX\ prints a warning at
-% the end of the \LaTeX\ run. To notify \LaTeX\ and
-% get a normal warning, just use
-% \begin{quote}
-% \cs{refused} |{|\meta{reference}|}|
-% \end{quote}
-% outside the expanding context. Example, see above.
-%
-% \subsubsection{Check for undefined references}
-%
-% In version 3.2 macros were added, that test, whether references
-% are defined.
-% \begin{declcs}{IfRefUndefinedExpandable} \M{refname} \M{then} \M{else}\\
-% \cs{IfRefUndefinedBabel} \M{refname} \M{then} \M{else}
-% \end{declcs}
-% If the reference is not available and therefore undefined, then
-% argument \meta{then} is executed, otherwise argument \meta{else}
-% is called. Macro \cs{IfRefUndefinedExpandable} is expandable,
-% but \meta{refname} must not contain babel shorthand characters.
-% Macro \cs{IfRefUndefinedBabel} supports shorthand characters of
-% babel, but it is not expandable.
-%
-% \subsection{Notes}
-%
-% \begin{itemize}
-% \item
-% The method of extracting the number in this
-% package also works in cases, where the
-% reference cannot be used directly, because
-% a package such as \xpackage{hyperref} has added
-% extra stuff (hyper link), so that the reference cannot
-% be used as number any more.
-% \item
-% If the reference does not contain a number,
-% assignments to a counter will fail of course.

-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{refcount}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/refcount.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/refcount.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 refcount.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):

-% 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{refcount.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 refcount.dtx
-%makeindex -s gind.ist refcount.idx
-%pdflatex refcount.dtx
-%makeindex -s gind.ist refcount.idx

-% \maketitle
-%
-% \begin{abstract}
-% This package extends package \xpackage{soul} and adds some support
-% for UTF-8. Namely the input encodings \xfile{utf8.def}
-% from package \xpackage{inputenc} and
-% package \xpackage{ucs}'s \xfile{utf8x.def} are supported.
-% \end{abstract}
-%
-% \tableofcontents
-%
-% \section{Documentation}
-%
-% This package \xpackage{soulutf8} does not have own options and does not
-% define new user commands.
-% Any option is passed to package \xpackage{soul} \cite{soul}
-% that is loaded first.
-% Then some internal macros of \xpackage{soul} are redefined to add
-% support for UTF-8.
-% The following input encodings are supported:
-% \begin{quote}
-% \begin{tabular}{@{}lll@{}}
-% \texttt{utf8} & \LaTeX\ base &
-% \xfile{TDS:tex/latex/base/utf8.def} \cite{utf8}\\
-% \texttt{utf8x} & Package \xpackage{ucs} &
-% \xfile{TDS:tex/latex/ucs/utf8x.def} \cite{ucs}\\
-% \end{tabular}
-% \end{quote}
-% UTF-8 byte sequences are added as token group to a word, even
-% if these UTF-8 characters are some kind of hyphen or space.
-% As exception the following three Unicode characters are handled specially:
-% \begin{quote}
-% \begin{tabular}{lll}
-% Slot & Name & Action\\
-% \hline
-% \texttt{U+00A0} & NO-BREAK SPACE & like |~|\\
-% \texttt{U+2013} & EN DASH & |--|\\
-% \texttt{U+2014} & EM DASH & |---|
-% \end{tabular}
-%
-% \subsection{Patch}
-%
-% Also package \xpackage{soulutf8} tries to patch package \xpackage{soul}
-% to improve its behaviour:
-% \begin{itemize}
-% \item
-% A problem with additional levels of curly braces is fixed.
-% As advantage more implicite kernings are detected.
-% However, the result may be incompatible with the
-% original behaviour of package \xpackage{soul} because
-% of these respected implicite kernings.
-% \item
-% \eTeX\ , especially \cs{unexpanded} is supported.
-% This allows a better protection of token groups
-% (|\mbox{|\dots|}|, math, \dots).
-% \end{itemize}
-% \end{quote}
-%
-% \subsection{Future}
-%
-% Currently package \xpackage{soul} does not seem to be
-% maintained. Nevertheless if there will be a new version that
-% adds support for UTF-8, then this package may become
-% obsolete.

-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{soulutf8}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/soulutf8.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/soulutf8.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 soulutf8.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{soulutf8.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 soulutf8.dtx
-%makeindex -s gind.ist soulutf8.idx
-%pdflatex soulutf8.dtx
-%makeindex -s gind.ist soulutf8.idx
-%pdflatex soulutf8.dtx

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{uniquecounter}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/uniquecounter.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/uniquecounter.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 uniquecounter.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{uniquecounter.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 uniquecounter.dtx
-%makeindex -s gind.ist uniquecounter.idx
-%pdflatex uniquecounter.dtx
-%makeindex -s gind.ist uniquecounter.idx
-%pdflatex uniquecounter.dtx
-%\end{verbatim}
