%
% \begin{abstract}
% There are macro and environment arguments that expect numbers
% that will internally be multiplicated with \cs{unitlength}.
% This package extends the syntax of these arguments that
% dimens with calculation support can be added for these arguments.
% \end{abstract}
%
% \tableofcontents
%
% \section{User interface}
%
% \subsection{Introduction}
%
% The environment |picture| and macros such as \cs{put}, \cs{line},
% \cs{vector} and other macros have arguments that expect numbers
% that are used as factor for \cs{unitlength}.
% This package redefines such macros and adds code that detects
% whether such an argument is given as number or as length.
% In the latter case, the length is used directly without multiplying
% with \cs{unitlength}.
%
% \subsection{Options}
%
% Depending on the available features, also length expressions
% can be given. Option \xoption{calc} loads package \xpackage{calc}.
% Then expressions of these package may be used.
% Otherwise \xoption{etex} wraps the length argument inside
% \cs{dimexpr}\dots\cs{relax}, if \eTeX\ is available. Otherwise
% option \xoption{plain} uses plain assignments without calculation
% support.
%
% The default is \xoption{calc} if package \xpackage{calc}
% is loaded before package \xoption{picture}. If you specify
% option \xoption{calc} the loading of \xpackage{calc} is ensured.
% Otherwise package \xpackage{picture} looks whether \cs{dimexpr}
% is available and uses then option \xoption{etex} as default.
% If \eTeX\ also could not be found, then \xoption{plain} is used.
%
% \subsection{Example}
%
%    \begin{macrocode}
%<*example>
\documentclass{article}

\usepackage[calc]{picture}

\begin{document}

\setlength{\unitlength}{1pt}

\begin{picture}(\widthof{Hello World}, 10mm)
  \put(0, 0){\makebox(0,0)[lb]{Hello World}}%
  \put(0, \heightof{Hello World} + \fboxsep){%
    \line(1, 0){\widthof{Hello World}}%
  }%
  \put(\widthof{Hello World}, 10mm){%
    \line(0, -1){10mm}%
  }%
\end{picture}

\end{document}
%</example>
%    \end{macrocode}
%
% \subsection{Supported packages}
%
% Packages \xpackage{pspicture} and \xpackage{pict2e} are supported,
% but they must be loaded before package \xpackage{picture}.
%
% New macros can be supported by \cs{picture@redefine}.
% The first argument is the macro which contains the arguments
% in its parameter text that you want to support by package \xpackage{picture}.
% The second argument contains the parameter text. Change \# to \& for
% the arguments in question.
% Examples (already used by package \xpackage{picture}):
% \begin{quote}
% |\picture@redefine\put{(&1,&2)}|\\
% |\picture@redefine\line{(#1,#2)&3}|
% \end{quote}

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