+% \section{Introduction}
+%
+% 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{The beginning}
+%
+% This package \xpackage{kvoptions} addresses class or package writers
+% that want to allow their users to specify options
+% as key value pairs, e.g.:
+% \begin{quote}
+% |\documentclass[verbose=false,name=me]{myclass}|\\
+% |\usepackage[format=print]{mylayout}|
+% \end{quote}
+% Prominent example is package \xpackage{hyperref},
+% probably the first package that offers this service.
+% It's \cs{ProcessOptionsWithKV} is often copied und
+% used in other packages, e.g. package \xpackage{helvet}
+% that uses this interface for its option \xoption{scaled}.
+%
+% However copying code is not the most modern software
+% development technique. And \xpackage{hyperref}'s
+% code for \cs{ProcessOptionsWithKV} was changed
+% to fix bugs. The version used in other packages
+% depends on the time of copying and the awareness
+% of \xpackage{hyperref}'s changes.
+% Now the code is sourced out into this package and
+% available for other package or class writers.
+%
+% \subsection{Overview}
+%
+% Package \xpackage{kvoptions} connects package
+% \xpackage{\emph{k}ey\emph{v}al}
+% with \LaTeX's package and class \emph{options}:

+% \section{Usage}
+%
+% \subsection{Process options}
+%
+% \subsubsection{\cs{ProcessKeyvalOptions}}
+%
+% \begin{declcs}{ProcessKeyvalOptions}\,\M{family}\\
+% \cs{ProcessKeyvalOptions} \*
+% \end{declcs}
+% This command evaluates the global or local options of
+% the package that are defined with \xpackage{keyval}'s
+% interface within the family \meta{family}. It acts the
+% same way as \LaTeX's \cs{ProcessOptions*}. In a package
+% unknown global options are ignored, in a class they
+% are added to the unknown option list. The known global
+% options and all local options are passed to \xpackage{keyval}'s
+% \cs{setkeys} command for executing the options.
+% Unknown options are reported to the user by an error.
+%
+% If the family name happens to be the same as the name
+% of the package or class where \cs{ProcessKeyvalOptions}
+% is used or the family name has previously been setup by
+% \cs{SetupKeyvalOptions}, then \cs{ProcessKeyvalOptions}
+% knows the family name already and you can use the star form
+% without mandatory argument.
+%
+% \subsubsection{\cs{ProcessLocalKeyvalOptions}}
+%
+% \begin{declcs}{ProcessLocalKeyvalOptions}\,\M{family}\\
+% \cs{ProcessLocalKeyvalOptions} \*
+% \end{declcs}
+% This macro has the same syntax and works similar as
+% \cs{ProcessKeyvalOptions}. However it ignores
+% global options and only processes the local package options.
+% Therefore it only can be used inside a package.
+% An error is thrown, if it is used inside a class.
+%
+% Neither of the following macros are necessary for
+% \cs{ProcessKeyvalOptions{}}. They just help the package/class
+% author in common tasks.
+%
+% \subsubsection{\cs{SetupKeyvalOptions}}\label{setup}
+%
+% \begin{declcs}{SetupKeyvalOptions}\,\texttt{\{}\\
+% \hspace{1.5em}|family|\,|=|\,\meta{family}|,|\\
+% \hspace{1.5em}|prefix|\,|=|\,\meta{prefix}\\
+% \hspace{1.5em}|setkeys|\,|=|\,\meta{setkeys command}\\
+% \texttt{\}}
+% \end{declcs}
+% This command allows to configure the default assumptions
+% that are based on the current package or class name.
+% \LaTeX\ remembers this name in \cs{@currname}. The syntax
+% description of the default looks a little weird, therefor
+% an example is given for a package or class named |foobar|.
+% \begin{quote}
+% \begin{tabular}{@{}l|ll|l@{}}
+% Key & Default & (example) & Used by\\
+% \hline
+% \rule{0pt}{1.2\ht\csname @arstrutbox\endcsname}^^A
+% |family| & \meta{\cs{@currname}} & (|foobar|)
+% & \cs{ProcessKeyvalOptions*} \\
+% &&& \cs{DeclareBoolOption} \\
+% &&& \cs{DeclareStringOption} \\
+% \hline
+% \rule{0pt}{1.2\ht\csname @arstrutbox\endcsname}^^A
+% |prefix| & \meta{\cs{@currname}}|@| & (|foobar@|)
+% & \cs{DeclareBoolOption} \\
+% &&& \cs{DeclareStringOption} \\
+% &&& \cs{DeclareVoidOption} \\
+% \hline
+% \rule{0pt}{1.2\ht\csname @arstrutbox\endcsname}^^A
+% |setkeys| & \cs{setkeys} & (\cs{kvsetkeys})
+% & \cs{ProcessKeyvalOptions} \\
+% &&& \cs{ProcessLocalKeyvalOptions}
+% \end{tabular}
+% \end{quote}
+% Key |setkeys| was added in version 3.9. The original
+% \cs{setkeys} of package \xpackage{keyval} is not reentrant.
+% If an option is processed by this \cs{setkeys}, then
+% the option should not call \cs{setkeys} again with a
+% different family. Otherwise the next options of the
+% first \cs{setkeys} call are processed with the wrong
+% family. With key |setkeys| the macro \cs{kvsetkeys}
+% can be set that does not have the problem of the
+% original \cs{setkeys} of package {keyval}.
+%
+% Probably \cs{setkeys} of package \xpackage{xkeyval}
+% is safe in this respect. But I haven't made a full
+% analysis. At least it does not have the problem
+% of the original \cs{setkeys}.
+%
+% \subsection{Option declarations}
+%
+% The options for \cs{ProcessKeyvalOptions} are defined
+% by \xpackage{keyval}'s \cs{define at key}.
+% Common purposes of such keys are boolean switches, they
+% enable or disable something. Or they store a name or some kind of
+% string in a macro. The following commands help the user. He
+% declares what he wants and \xpackage{kvoptions} take care of
+% the key definition, resource allocation and initialization.
+%
+% In order to avoid name clashes of macro names, internal
+% commands are prefixed. Both the prefix and the family
+% name for the defined keys can be configured by
+% \cs{SetupKeyvalOptions}.
+%
+% \subsubsection{\cs{DeclareStringOption}}
+%
+% \begin{declcs}{DeclareStringOption}\,\O{init}\,\M{key}\,\O{default}
+% \end{declcs}
+% A macro is created that remembers the value of the key \meta{key}.
+% The name of the macro consists of the option name \meta{key} that
+% is prefixed by the prefix (see \ref{setup}).
+% The initial contents of the
+% macro can be given by the first optional argument \meta{init}.
+% The default is empty.
+%
+% The the option \meta{key} is defined. The option code
+% just stores its value in the macro. If the optional argument
+% at the end of \cs{DeclareStringOption} is given, then option
+% \meta{key} is defined with the default \meta{default}.
+%
+% Example for a package with the following two lines:
+% \begin{quote}
+% |\ProvidesPackage{foobar}|\\
+% |\DeclareStringOption[me]{name}|
+% \end{quote}
+% Then \cs{DeclareStringOption} defines the macro with content |me|,
+% note \LaTeX\ complains if the name of the macro already exists:
+% \begin{quote}
+% |\newcommand*{\foobar at name}{me}|
+% \end{quote}
+% The option definition is similar to:
+% \begin{quote}
+% |\define at key{foobar}{name}{%|\\
+% | \renewcommand*{\foobar at name}{#1}%|\\
+% |}|
+% \end{quote}
+%
+% \subsubsection{\cs{DeclareBoolOption}}
+%
+% \begin{declcs}{DeclareBoolOption}\,\O{init}\,\M{key}
+% \end{declcs}
+% A boolean switch is generated, initialized by value \meta{init}
+% and the corresponding key \meta{key} is defined. If the
+% initialization value is not given, |false| is used as default.
+%
+% The internal actions of \cs{DeclareBoolOption} are shown below.
+% The example is given for a package author who has the following
+% two lines in his package/class:
+% \begin{quote}
+% |\ProvidesPackage{foobar}|\\
+% |\DeclareBoolOption{verbose}|
+% \end{quote}
+% First a new switch is created:
+% \begin{quote}
+% |\newif\iffoobar at verbose|
+% \end{quote}
+% and initialized:
+% \begin{quote}
+% |\foobar at verbosefalse|
+% \end{quote}
+% Finally the key is defined:
+% \begin{quote}
+% |\define at key{foobar}{verbose}[true]{|\dots|}|
+% \end{quote}
+% The option code configures the boolean option in the following way:
+% If the author specifies |true| or |false| then the switch is
+% turned on or off respectivly. Also the option can be given without
+% explicit value. Then the switch is enabled.
+% Other values are reported as errors.
+%
+% Now the switch is ready to use in the package/class, e.g.:
+% \begin{quote}
+% |\iffoobar at verbose|\\
+% \qquad\textit{\% print verbose message}\\
+% |\else|\\
+% \qquad\textit{\% be quiet}\\
+% |\fi|
+% \end{quote}
+% Users of package \cs{ifthen} can use the switch as
+% boolean:
+% \begin{quote}
+% |\boolean{foobar at verbose}|
+% \end{quote}
+%
+% \subsubsection{\cs{DeclareComplementaryOption}}
+%
+% \begin{declcs}{DeclareComplementaryOption}\,\M{key}\,\M{parent}
+% \end{declcs}
+% Sometimes contrasting names are used to characterize the
+% two states of a boolean switch, for example \xoption{draft}
+% vs.\@ \xoption{final}. Both options behave like boolean
+% options but they do not need two different switches, they
+% should share one. \cs{DeclareComplementaryOption} allows this.
+% The option \meta{key} shares the switch of option \meta{parent}.
+% Example:
+% \begin{quote}
+% |\DeclareBoolOption{draft}|\\
+% |\DeclareComplementaryOption{final}{draft}|
+% \end{quote}
+% Then |final| sets the switch of \xoption{draft} to |false|, and
+% |final=false| enables the \xoption{draft} switch.
+%
+% \subsubsection{\cs{DeclareVoidOption}}
+%
+% \begin{declcs}{DeclareVoidOption}\,\M{key}\,\M{code}
+% \end{declcs}
+% \cs{ProcessKeyvalOptions} can be extended to recognize
+% options that are declared in traditional way by \cs{DeclareOption}.
+% But in case of the error that the user specifies a value, then
+% this option would not recognized as key value option because
+% of \cs{DeclareOption} and not detected as traditional option
+% because of the value part. The user would get an unknown option
+% error, difficult to understand.
+%
+% \cs{DeclareVoidOption} solves
+% this problem. It defines the option \meta{key} as key value option.
+% If the user specifies a value, a warning is given and the
+% value is ignored.
+%
+% The code part \meta{code} is stored in a macro.
+% The name of the macro consists of the option name \meta{key} that
+% is prefixed by the prefix (see \ref{setup}).
+% If the option is set, the macro will be executed. During the
+% execution \cs{CurrentOption} is available with the current key name.
+%
+% \subsubsection{\cs{DeclareDefaultOption}}
+%
+% \begin{declcs}{DeclareDefaultOption}\,\M{code}
+% \end{declcs}
+% \begin{sloppypar}
+% This command does not define a specific key, it is the equivalent
+% to \LaTeX's \cs{DeclareOption*}. It allows the specification
+% of a default action \meta{code} that is invoked if an unknown option
+% is found.
+% While \meta{code} is called,
+% macro \cs{CurrentOption} contains the current option string.
+% In addition \cs{CurrentOptionValue} contains the value part
+% if the option string is parsable as key value pair, otherwise
+% it is \cs{relax}. \cs{CurrentOptionKey} contains the key of
+% the key value pair, or the whole option string, if it misses
+% the equal sign.
+% \end{sloppypar}
+%
+% Inside packages typical default actions are to pass unknown
+% options to another package. Or an error message can be thrown
+% by \cs{@unknownoptionerror}. This is the original error
+% message that \LaTeX\ gives for unkown package options.
+% This error message is easier to understand for the user
+% as the error message from package \xpackage{keyval} that
+% is given otherwise.
+%
+% A Class ignores unknown options and puts them on the
+% unused option list. Let \LaTeX\ do the job and just
+% call \cs{OptionNotUsed}. Or the options can be passed to
+% another class that is later loaded.
+%
+% \subsubsection{Local options}
+%
+% \begin{declcs}{DeclareLocalOption} \M{option}\\
+% \cs{DeclareLocalOptions} \M{option list}
+% \end{declcs}
+% Both macros mark package options as local options. That means
+% that they are ignored by \cs{ProcessKeyvalOptions} if they are given
+% as global options. \cs{DeclareLocalOptions} takes one option,
+% \cs{DeclareLocalOptions} expects a comma separated list of options.
+%
+% \subsubsection{Dynamic options}
+%
+% Options of \LaTeX's package/class system are cleared
+% in \cs{ProcessOptions}. They modify the static model
+% of a package. For example, depending on option \xoption{bookmarks}
+% package \xpackage{hyperref} loads differently.
+%
+% Options, however,
+% defined by \xpackage{keyval}'s \cs{define at key} remain
+% defined, if the options are processed by \cs{setkeys}.
+% Therefore these options can also be used to model
+% the dynamic behaviour of a package. For example, in
+% \xpackage{hyperref} the link colors can be changed
+% everywhere until the end in |\end{document}|.
+%
+% However package \xpackage{color} that adds color support
+% is necessary and it
+% cannot be loaded after |\begin{document}|. Option \xoption{colorlinks}
+% that loads \xpackage{color} should be active until |\begin{document}|
+% and die in some way if it is too late for loading packages.
+% With \cs{DisableKeyvalOption} the package/class author can
+% specify and configure the death of an option and controls
+% the life period of the option.
+%
+% \subsubsection{\cs{DisableKeyvalOption}}
+%
+% \begin{declcs}{DisableKeyvalOption}\,\O{options}\,\M{family}\,\M{key}
+% \\[0.5ex]
+% \meta{options}:\\
+% \hspace{1.5em}^^A
+% \begin{tabular}[t]{@{}l@{ \texttt{=} }l@{\qquad}>{default: }l@{}}
+% |action| & |undef|, |warning|, |error|, or |ignore|
+% & |undef|
+% \\
+% \multicolumn{1}{@{}l}{|global| or |local|} & & |global|
+% \\
+% |package| or |class| & \meta{name}
+% \\
+% \end{tabular}^^A
+% \end{declcs}
+% \cs{DisableKeyvalOption} can be called to mark the end when
+% the option \meta{key} is no longer useful. The behaviour of
+% an option after its death can be configured by \xoption{action}:
+% \begin{description}
+% \item[\texttt{undef}:] The option will be undefined,
+% If it is called, \cs{setkeys} reports an error because
+% of unknown key.
+% \item[\texttt{error} or \texttt{warning}:] Use of the
+% option will cause an error or warning message.
+% Also these actions require that exclusivly either the
+% package or class name is given in options \xoption{package}
+% or \xoption{class}.
+% \item[\texttt{ignore}:] The use of the option will silently
+% be ignored.
+% \end{description}
+% The option's death can be limited to the end of the current
+% group, if option \xoption{local} is given. Default is
+% \xoption{global}.
+%
+% The package/class author can wish the end of the option
+% already during the package loading, then he will have
+% static behaviour. In case of dynamic options \cs{DisableKeyvalOption}
+% can be executed everywhere, also outside the package. Therefore
+% the family name and the package/class name is usually unknown for
+% \cs{DisableKeyvalOption}. Therefore the argument for the family
+% name is mandatory and for some actions the package/class name
+% must be provided.
+%
+% Usually a macro would configure the option death, Example:
+%\begin{quote}
+%\begin{verbatim}
+%\ProvidesPackage{foobar}
+%\DeclareBoolOption{color}
+%\DeclareStringOption[red]{emphcolor}
+%\ProcessKeyvalOptions*
+%
+%\newcommand*{\foobar at DisableOption}[2]{%
+% \DisableKeyvalueOption[
+% action={#1},
+% package=foobar
+% ]{foobar}{#2}%
+%}
+%
+%\iffoobar at color
+% \RequirePackage{color}
+% \renewcommand*{\emph}[1]{\textcolor{\foobar at emphcolor}{#1}}
+%\else
+% % Option emphcolor is not wrong, if we have color support.
+% % otherwise the option has no effect, but we don't want to
+% % remove it. Therefore action 'ignore' is the best choice:
+% \foobar at DisableOption{ignore}{emphcolor}
+%\fi
+%% No we don't need the option 'color'.
+%\foobar at DisableOption{warning}{color}
+%
+%% With color support option 'emphcolor' will dynamically
+%% change the color of \emph statements.
+%\end{verbatim}
+%\end{quote}
+%
+% \subsubsection{\cs{AddToKeyvalOption}}
+%
+% \begin{declcs}{AddToKeyvalOption}\,\M{family}\,\M{key}\,\M{code}\\
+% \cs{AddToKeyvalOption} \*\,\M{key}\,\M{code}
+% \end{declcs}
+% The code for an existing key \meta{key} of family \meta{family} is
+% extended by code \meta{code}. In the starred form the current
+% family setting is used, see \cs{ProcessKeyvalOptions*}.
+%
+% \subsection{Global vs. local options}
+%
+% Options that are given for \cs{documentclass} are called
+% global options. They are known to the class and all packages.
+% A package may make use of a global option and marks it as
+% used. The advantage for the user is the freedom to specify
+% options both in the \cs{documentclass} or \cs{usepackage}
+% commands.
+%
+% However global options are shared with the class options
+% and options of all other packages. Thus there can be the
+% same option with different semantics for different
+% packages and classes. As example, package \xpackage{bookmark}
+% knows option \xoption{open} that specifies whether the bookmarks
+% are opened or closed initially. It's values are |true| or |false|.
+% Since KOMA-Script version 3.00 the KOMA classes also introduces
+% option \xoption{open} with values |right| and |any| and a
+% complete different meaning.
+%
+% Such conflicts can be resolved by marking all or part of options
+% as local by \cs{DeclareLocalOption} or \cs{DeclareLocalOptions}.
+% Then the packages ignores global occurences of these options.
+% Package \xpackage{kvoptions} provides two methods:
+% \begin{itemize}
+% \item \cs{ProcessLocalKeyvalOptions} automatically uses all options
+% as local options. It ignores all global options.
+% \item \cs{DeclareLocalOption} or \cs{DeclareLocalOptions} marks
+% options as local options. \cs{ProcessKeyvalOptions} will then
+% ignore global occurences for these local options.
+% \end{itemize}
+% Since version 1.5 package \xpackage{bookmark} uses the latter
+% method. It checks global and local option places for driver options
+% and limits all other options as local options. Thus the class
+% option \xoption{open} of KOMA-Script is not misread as
+% option for package \xpackage{bookmark}.
+%
+% \subsection{Summary of internal macros}
+%
+% The \cs{Declare}\texttt{\dots Option} commands define
+% macros, additionally to the macros generated by the key definition.
+% These macros can be used by the package/class author.
+% The name of the macros starts with the prefix \meta{prefix}
+% that can be configured by \cs{SetupKeyvalOptions}.
+% \begin{center}
+% \def\prefix{\cs{}\meta{prefix}\meta{key}}^^A
+% \def\Hline{^^A
+% \hline
+% \rule{0pt}{1.2\ht\csname @arstrutbox\endcsname}^^A
+% }^^A
+% \begin{tabular}{@{}l|>{\ttfamily}l|l@{}}
+% Declare \meta{key} & \textrm{Defined macro} & Description\\
+% \Hline
+% \cs{DeclareStringOption}
+% & \prefix & holds the string\\
+% \Hline
+% \cs{DeclareBoolOption}
+% & \cs{if}\meta{prefix}\meta{key}& boolean switch\\
+% &\prefix false& disable switch\\
+% &\prefix true& enable switch\\
+% \Hline
+% \cs{DeclareComplementaryOption}
+% & \prefix false& enable parent switch\\
+% & \prefix true& disable parent switch\\
+% \Hline
+% \cs{DeclareVoidOption}
+% & \prefix & holds the action
+% \end{tabular}
+% \end{center}
+%
+% \subsection{\plainTeX}
+%
+% Package \xpackage{keyval} is also usable in \plainTeX\ with
+% the help of file \xfile{miniltx.tex}. Some features of this
+% package \xpackage{kvoptions} might also be useful for \plainTeX.
+% If \LaTeX\ is not found, \cs{ProcessKeyvalOptions} and option
+% \xoption{patch} are disabled. Before using the option declaration
+% commands \cs{Declare...Option}, \cs{SetupKeyvalOptions} must be
+% used.
+%
+% \hypersetup{bookmarksopenlevel=1}
+%
+% \section{Example}
+%
+% The following example defined a package that serves some
+% private color management. A boolean option \xoption{print} enables
+% print mode without colors. An option \xoption{emph} redefines
+% \cs{emph} to print in the given color. And the driver
+% can be specified by option \xoption{driver}.

+% \section{Package options}
+%
+% The package \xpackage{kvoptions} knows two package options
+% \xoption{patch} and \xoption{debugshow}.
+% The options of package \xpackage{kvoptions} are intended
+% for authors, not for package/class writers. Inside a package
+% it is too late for option \xoption{patch} and \xoption{debugshow}
+% enables some messages that are perhaps useful for the debugging
+% phase. Also \LaTeX\ is unhappy if a package is loaded
+% later again with options that are previously not given.
+% Thus package and class authors, stay with |\RequirePackage{kvoptions}|
+% without options.
+%
+% Option \xoption{patch} loads package \xpackage{kvoptions-patch}.
+%
+% \subsection{Package \xpackage{kvoptions-patch}}
+%
+% \LaTeX's system of package/class options has some severe limitations
+% that especially affects the value part if options are used as
+% pair of key and value.
+% \begin{itemize}
+% \item Spaces are removed, regardless where:
+% \begin{quote}
+% |\documentclass[box=0 0 400 600]{article}|
+% \end{quote}
+% Now each package will see |box=00400600| as global option.
+% \item In the previous case also braces would not help:
+% \begin{quote}
+% |\documentclass[box={0 0 400 600}]{article}|
+% \end{quote}
+% The result is an error message:
+% \begin{quote}
+% |! LaTeX Error: Missing \begin{document}.|
+% \end{quote}
+% As local option, however, it works if the package
+% knows about key value options (By using this package, for example).
+% \item The requirements on robustness are extremly high.
+% \LaTeX\ expands the option. All that will not work as environment
+% name will break also as option. Even a \cs{relax} will generate
+% an error message:
+% \begin{quote}
+% |! Missing \endcsname inserted.|
+% \end{quote}
+% Of course, \LaTeX\ does not use its protecting mechanisms.
+% On contrary \cs{protect} itself will cause errors.
+% \item The options are expanded. But perhaps the package will
+% do that, because it has to setup some things before?
+% Example \xpackage{hyperref}:
+% \begin{quote}
+% |\usepackage[pdfauthor=M\"uller]{hyperref}|
+% \end{quote}
+% Package \xpackage{hyperref} does not see |M\"uller| but
+% its expansion and it does not like it, you get many warnings
+% \begin{quote}
+% |Token not allowed in a PDFDocEncoded string|
+% \end{quote}
+% And the title becomes: |Mu127uller|.
+% Therefore such options must usually be given after package
+% \xpackage{hyperref}
+% is loaded:
+% \begin{quote}
+% |\usepackage{hyperref}|\\
+% |\hypersetup{pdfauthor=Fran\c coise M\"uller}|
+% \end{quote}
+% As package option it will even break with |Fran\c coise|
+% because of the cedilla |\c c|, it is not robust enough.
+% \end{itemize}
+% For users that do not want with this limitations the package
+% offers package \xoption{kvoptions-patch}. It patches \LaTeX's option system
+% and tries to teach it also to handle options that are given
+% as pairs of key and value and to prevent expansion.
+% It can already be used at the very beginning, before \cs{documentclass}:
+% \begin{quote}
+% |\RequirePackage{kvoptions-patch}|\\
+% |\documentclass[pdfauthor=Fran\c coise M\"uller]{article}|\\
+% |\usepackage{hyperref}|
+% \end{quote}
+% The latest time is before the package where you want to use
+% problematic values:
+% \begin{quote}
+% |\usepackage{kvoptions-patch}|\\
+% |\usepackage[Fran\c coise M\"uller]{hyperref}|
+% \end{quote}
+% Some remarks:
+% \begin{itemize}
+% \item The patch requires \eTeX, its \cs{unexpanded} feature
+% is much too nice. It is possible to work around using token
+% registers. But the code becomes longer, slower, more difficult
+% to read and maintain. The package without option \xoption{patch}
+% works and will work without \eTeX.
+% \item The code for the patch is quite long, there are many test
+% cases. Thus the probability for bugs is probably not too small.
+% \item Since 2008/10/18 v3.0 package \xpackage{kvoptions-patch} is
+% available. Before option \xoption{patch} of package \xpackage{kvoptions}
+% must be used instead. I think, the solution as standalone package
+% \xpackage{kvoptions-patch} is cleaner and avoids option clashes.
+% \end{itemize}
+%
+% \subsection{Option \xoption{debugshow}}
+%
+% The name of this option follows the convention of packages
+% \xpackage{multicol}, \xpackage{tabularx}, and \xpackage{tracefnt}.
+% Currently it prints the setting of boolean options, declared
+% by \cs{DeclareBoolOption} in the \xfile{.log} file, if that
+% boolean option is used.
+% You can activate the option by
+% \begin{itemize}
+% \item |\PassOptionsToPackage{debugshow}{kvoptions}|\\
+% Put this somewhere before package \xpackage{kvoptions} is
+% loaded first, e.g. before \cs{documentclass}.
+% \item |\RequirePackage[debugshow]{kvoptions}|\\
+% Before \cs{documentclass} even an author has to use
+% \cs{RequirePackage}. \cs{usepackage} only works after
+% \cs{documentclass}.
+% \end{itemize}
+% The preferred method is \cs{PassOptionsToPackage}, because
+% it does not force the package loading and does not disturb,
+% if the package is not loaded later at all.
+%
+% \section{Limitations}
+%
+% \subsection{Compatibility}
+% \subsubsection{Package \xpackage{kvoptions-patch} vs. package \xpackage{xkvltxp}}
+%
+% Package \xpackage{xkvltxp} from the \xpackage{xkeyval} project
+% has the same goal as package \xpackage{kvoptions-patch}
+% and to patch \LaTeX's kernel commands in order to get better support
+% for key value options.
+% Of course they cannot be used both. The user must decide, which
+% method he prefers. Package \xpackage{kvoptions-patch} aborts itself,
+% if it detects that \xpackage{xkvltxp} is
+% already loaded.
+%
+% However package \xpackage{xkvltxp} and \xpackage{kvoptions}
+% can be used together, example:
+% \begin{quote}
+% |\usepackage{xkvltxp}|\\
+% |\usepackage[...]{foobar} % |\texttt{\itshape foobar using kvoptions}
+% \end{quote}
+% The other way should work, too.
+%
+% Package \xpackage{kvoptions-patch} tries to catch more situations
+% and to be more robust.
+% For example, during the comparison of options it normalizes
+% them by removing spaces around |=| and the value. Thus the
+% following is not reported as option clash:
+% \begin{quote}
+%\begin{verbatim}
+%\RequirePackage{kvoptions-patch}
+%\documentclass{article}
+%
+%\usepackage[scaled=0.7]{helvet}
+%\usepackage[scaled = 0.7]{helvet}
+%
+%\begin{document}
+%\end{document}
+%\end{verbatim}
+% \end{quote}
+%
+% \subsection{Limitations}
+%
+% \subsubsection{Option comparisons}
+%
+% In some situations \LaTeX\ compares option lists, e.g. option clash check,
+% \cs{@ifpackagewith}, or \cs{@ifclasswith}. Apart from catcode and
+% sanitizing problems of option \xoption{patch}, there is another problem.
+% \LaTeX\ does not know about the type and default values of
+% options in key value style. Thus an option clash is reported,
+% even if the key value has the same meaning:
+% \begin{quote}
+% |\usepackage[scaled]{helvet} %| \texttt{\textit{default is }.95}\\
+% |\usepackage[.95]{helvet}|\\
+% |\usepackage[0.95]{helvet}|
+% \end{quote}
+%
+% \subsubsection{Option list parsing with package \xpackage{kvoptions-patch}}
+%
+% With package \xpackage{kvoptions-patch} the range of possible values
+% in key value specifications is much large, for example
+% the comma can be used, if enclosed in curly braces.
+%
+% Other packages, especially the packages that uses their
+% own process option code can be surprised to find tokens
+% inside options that they do not expect and errors would
+% be the consequence. To avoid errors the options, especially
+% the unused option list is sanitized. That means the list
+% will only contain tokens with catcode 12 (other) and
+% perhaps spaces (catcode 10). This allows a safe parsing
+% for other packages. But a comma in the value part is
+% no longer protected by curly braces because they have lost
+% their special meaning. This is the price for compatibility.
+%
+% Example:
+% \begin{quote}
+% |\RequirePackage{kvoptions-patch}|\\
+% |\documentclass[a={a,b,c},b]{article}|\\
+% |\begin{document}|\\
+% |\end{document}|
+% \end{quote}
+% Result:
+% \begin{quote}
+% |LaTeX Warning: Unused global option(s):|\\
+% | [a={a,c},b].|

+%
+% \begin{macro}{\KVO at family}
+% We cannot store the family setting in one macro,

+% here. The default is the package name with |@| appended.

+% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{kvoptions}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/kvoptions/kvoptions.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/kvoptions/kvoptions.pdf}] Documentation.
+% \end{description}
+%
+%
+% \paragraph{Bundle.} All the packages of the bundle `kvoptions'
+% 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/kvoptions.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{kvoptions.tds.zip} in the
+% TDS tree (also known as \xfile{texmf} tree) of your choice.
+% Example (linux):
+% \begin{quote}
+% |unzip kvoptions.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 kvoptions.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{kvoptions.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 kvoptions.dtx
+%makeindex -s gind.ist kvoptions.idx
+%pdflatex kvoptions.dtx
+%makeindex -s gind.ist kvoptions.idx
+%pdflatex kvoptions.dtx
