% Distribution:
%    CTAN:macros/latex/contrib/oberdiek/kvdefinekeys.dtx
%    CTAN:macros/latex/contrib/oberdiek/kvdefinekeys.pdf
%
% Unpacking:
%    (a) If kvdefinekeys.ins is present:
%           tex kvdefinekeys.ins
%    (b) Without kvdefinekeys.ins:
%           tex kvdefinekeys.dtx
%    (c) If you insist on using LaTeX
%           latex \let\install=y\input{kvdefinekeys.dtx}
%        (quote the arguments according to the demands of your shell)
%
% Documentation:
%    (a) If kvdefinekeys.drv is present:
%           latex kvdefinekeys.drv
%    (b) Without kvdefinekeys.drv:
%           latex kvdefinekeys.dtx; ...
%    The class ltxdoc loads the configuration file ltxdoc.cfg
%    if available. Here you can specify further options, e.g.
%    use A4 as paper format:
%       \PassOptionsToClass{a4paper}{article}
%
%    Programm calls to get the documentation (example):
%       pdflatex kvdefinekeys.dtx
%       makeindex -s gind.ist kvdefinekeys.idx
%       pdflatex kvdefinekeys.dtx
%       makeindex -s gind.ist kvdefinekeys.idx
%       pdflatex kvdefinekeys.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.

% \section{Documentation}
%
% \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.
% \end{itemize}

% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\url{http://ctan.org/pkg/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[\CTAN{install/macros/latex/contrib/oberdiek.tds.zip}]
% \end{description}
% \emph{TDS} refers to the standard ``A Directory Structure
% for \TeX\ Files'' (\CTAN{tds/tds.pdf}). 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}
%
% \paragraph{Script installation.}
% Check the directory \xfile{TDS:scripts/oberdiek/} for
% scripts that need further installation steps.
% Package \xpackage{attachfile2} comes with the Perl script
% \xfile{pdfatfi.pl} that should be installed in such a way
% that it can be called as \texttt{pdfatfi}.
% Example (linux):
% \begin{quote}
%   |chmod +x scripts/oberdiek/pdfatfi.pl|\\
%   |cp scripts/oberdiek/pdfatfi.pl /usr/local/bin/|
% \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
% (\teTeX, \mikTeX, \dots) relies on file name databases, you must refresh
% these. For example, \teTeX\ users run \verb|texhash| or
% \verb|mktexlsr|.
%
% \subsection{Some details for the interested}
%
% \paragraph{Attached source.}
%
% The PDF documentation on CTAN also includes the
% \xfile{.dtx} source file. It can be extracted by
% AcrobatReader 6 or higher. Another option is \textsf{pdftk},
% e.g. unpack the file into the current directory:
% \begin{quote}
%   \verb|pdftk kvdefinekeys.pdf unpack_files output .|
% \end{quote}
%
% \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
%makeindex -s gind.ist kvdefinekeys.idx
%pdflatex kvdefinekeys.dtx
%\end{verbatim}
% \end{quote}
