-% \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
