% Commands are defined for getting box sizes similar
% to \LaTeX's \cs{settowidth} commands.
% \end{abstract}
%
% \tableofcontents
%
% \section{Usage}
%
% \subsection{Get box dimensions}
%
% \begin{declcs}^^A
%   {settoboxwidth}\,\M{\LaTeX\ length}\,\M{\LaTeX\ box}\\
%   \SpecialUsageIndex{\settoboxheight}^^A
%   \cs{settoboxheight}\,\M{\LaTeX\ length}\,\M{\LaTeX\ box}\\
%   \SpecialUsageIndex{\settoboxdepth}^^A
%   \cs{settoboxdepth}\,\M{\LaTeX\ length}\,\M{\LaTeX\ box}\\
%   \SpecialUsageIndex{\settoboxtotalheight}^^A
%   \cs{settoboxtotalheight}\,\M{\LaTeX\ length}\,\M{\LaTeX\ box}
% \end{declcs}
% A \meta{\LaTeX\ box} is allocated by \cs{newsavebox}.
% It can be filled by \cs{sbox} or the environment \texttt{lrbox}.
% The commands above extract then the desired lengths.
%
% \subsection{Set box dimensions}
%
% \begin{declcs}^^A
%   {setboxwidth}\,\M{\LaTeX\ box}\,\M{\LaTeX\ length expression}\\
%   \SpecialUsageIndex{\setboxheight}^^A
%   \cs{setboxheight}\,\M{\LaTeX\ box}\,\M{\LaTeX\ length expression}\\
%   \SpecialUsageIndex{\setboxdepth}^^A
%   \cs{setboxdepth}\,\M{\LaTeX\ box}\,\M{\LaTeX\ length expression}
% \end{declcs}
% These commands allow the manipulation of the box. Package \xpackage{calc}
% is supported in the \meta{\LaTeX\ length expression}.
% Also the following length are available in this expression:
% \begin{quote}
% \begin{tabular}{@{}ll@{}}
%   \cs{width}& width of the box\\
%   \cs{height}& height of the box\\
%   \cs{depth}& depth of the box\\
%   \cs{totalheight}& totalheight of the box\\
% \end{tabular}
% \end{quote}
% Note, the base point (point at the left margin of the baseline)
% always remain constant.
%
% \subsection{Move box}
%
% \begin{declcs}^^A
%   {setboxmoveleft}\,\M{\LaTeX\ box}\,\M{\LaTeX\ length expression}\\
%   \SpecialUsageIndex{\setboxmoveright}^^A
%   \cs{setboxmoveright}\,\M{\LaTeX\ box}\,\M{\LaTeX\ length expression}\\
%   \SpecialUsageIndex{\setboxlower}^^A
%   \cs{setboxlower}\,\M{\LaTeX\ box}\,\M{\LaTeX\ length expression}\\
%   \SpecialUsageIndex{\setboxright}^^A
%   \cs{setboxright}\,\M{\LaTeX\ box}\,\M{\LaTeX\ length expression}
% \end{declcs}
% Note, the box is shifted relative to the base point. The base point
% is always inside the box, however the width and height of the
% box change along with the movement.
%
% \subsection{Example}
%
% \subsubsection{Short example}
%
% \begin{quote}
%\begin{verbatim}
%\newsavebox{\mybox}
%\newlength{\mylength}
%\sbox{\mybox}{Hello World}
%\settoboxwidth{\mylength}{\mybox}
%\end{verbatim}
% \end{quote}
%
% \subsubsection{Test file that shows box manipulations}
%
%    \begin{macrocode}
%<*example>
\documentclass{article}

\usepackage{settobox}
\usepackage{calc}

\newsavebox{\mybox}

\setlength{\fboxsep}{0pt}

\pagestyle{empty}

  % \test{#1}
  % The macro is called with commands in #1 that manipulates
  % the box \mybox. These commands along with the result of
  % the manipulation is shown. Thus the essence of the
  % macro is:
  %
  %   a) \sbox{\mybox}{The cracy fox.}
  %   b) #1 % manipulates \mybox
  %   c) Print #1 commands.
  %   d) Print box with frame

% \section{Installation}
%
% \paragraph{CTAN.} This package is available on
% CTAN\footnote{\url{ftp://ftp.ctan.org/tex-archive/}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/oberdiek/settobox.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/settobox.pdf}] Documentation.
% \end{description}
%
% \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 settobox.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}
% \sbox0{^^A
% \begin{tabular}{@{}>{\ttfamily}l@{$\quad\rightarrow\quad$}>{\ttfamily}l@{}}
%   settobox.sty & tex/latex/oberdiek/settobox.sty\\
%   settobox.pdf & doc/latex/oberdiek/settobox.pdf\\
%   settobox-example.tex & doc/latex/oberdiek/settobox-example.tex\\
%   settobox.dtx & source/latex/oberdiek/settobox.dtx\\
% \end{tabular}^^A
% }%
% \ifdim\wd0>\linewidth
%   \mbox{}\nobreak\hskip0pt minus\leftmargin
%   \usebox0
%   \nobreak\hskip0pt minus\rightmargin
% \else
%   \usebox0
% \fi
% \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.
%
% \paragraph{Refresh file databases.} If your \TeX~distribution
% (\teTeX, \mikTeX, \dots) rely on file 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 settobox.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{settobox.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 settobox.dtx
%makeindex -s gind.ist settobox.idx
%pdflatex settobox.dtx
%makeindex -s gind.ist settobox.idx
%pdflatex settobox.dtx
%\end{verbatim}
% \end{quote}
%
% \begin{History}
%   \begin{Version}{2000/02/11 v1.0}
%   \item
%     First public release, written as answer in the
%     newsgroup \xnewsgroup{de.comp.text.tex} in the thread
%     \textit{Die Hoehe von Minipages und Bild}, date: 2000/02/11.
