% \begin{abstract}
% This package adds a key value interface for tabular
% by the new environment \texttt{tabularkv}. Thus the
% \TeX\ source code looks better by named parameters,
% especially if package \xpackage{tabularht} is used.

%
% \section{Usage}
% \begin{quote}
%   |\usepackage{tabularkv}|
% \end{quote}
% The package provides the environment |tabularkv|
% that takes an optional argument with tabular
% parameters:
% \begin{description}
% \item[\texttt{width}:] width specification, "tabular*" is used.
% \item[\texttt{x}:]
%   width specification, |tabularx| is used,
%              package \xpackage{tabularx} must be loaded.
% \item[\texttt{height}:]
%   height specification, see package \xpackage{tabularht}.
% \item[\texttt{valign}:] vertical positioning, this option is optional;\\
%   values: top, bottom, center.
% \end{description}
% Parameter \xoption{valign} optional, the following are
% equivalent:
% \begin{quote}
%  |\begin{tabularkv}[|\dots|, valign=top]{l}|\dots|\end{tabularkv}|\\
%  |\begin{tabularkv}[|\dots|][t]{l}|\dots|\end{tabularkv}|
% \end{quote}

% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\CTANpkg{tabularkv}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/oberdiek/tabularkv.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/tabularkv.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 tabularkv.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
% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}}
%   tabularkv.sty & tex/latex/oberdiek/tabularkv.sty\\
%   tabularkv.pdf & doc/latex/oberdiek/tabularkv.pdf\\

% \end{quote}
% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
% TDS installing feature, then some files can already be in the right
% place, see the documentation of \docstrip.
%
% \subsection{Refresh file name databases}
%
% If your \TeX~distribution
% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
% these. For example, \TeX\,Live\ users run \verb|texhash| or
% \verb|mktexlsr|.
%
% \subsection{Some details for the interested}
%
% \paragraph{Unpacking with \LaTeX.}
% The \xfile{.dtx} chooses its action depending on the format:
% \begin{description}
% \item[\plainTeX:] Run \docstrip\ and extract the files.
% \item[\LaTeX:] Generate the documentation.
% \end{description}
% If you insist on using \LaTeX\ for \docstrip\ (really,
% \docstrip\ does not need \LaTeX), then inform the autodetect routine
% about your intention:
% \begin{quote}
%   \verb|latex \let\install=y\input{tabularkv.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 tabularkv.dtx
%makeindex -s gind.ist tabularkv.idx
%pdflatex tabularkv.dtx
%makeindex -s gind.ist tabularkv.idx
%pdflatex tabularkv.dtx
%\end{verbatim}
