+% \maketitle
+%
+% \begin{abstract}
+% This package adds an optional argument to \cs{stackrel} for
+% putting something below the relational symbol and defines
+% \cs{stackbin} for binary symbols.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{User interface}
+%
+% \LaTeX's \cs{stackrel} allows a superscript above a relational symbol,
+% but pure \LaTeX\ does not provide a macro for putting a subscript
+% below the symbol. This is supported by \AmS\LaTeX's \cs{underset}
+% macro that works on both relational and binary symbols. A combination
+% of \cs{underset} and \cs{overset} can be used to put \mbox{sub-} and
+% superscripts to the same symbol.
+%
+% This package \xpackage{stackrel} extends the syntax of \cs{stackrel}
+% by adding an optional argument for the subscript position.
+% It follows the syntax of extensible arrows of packages
+% \xpackage{amsmath} and \xpackage{mathtools}.
+%
+% \begin{declcs}{stackrel}
+%   |[|\meta{subscript}|]| \M{superscript} \M{rel}\\
+%   \cs{stackbin}
+%   |[|\meta{subscript}|]| \M{superscript} \M{bin}
+% \end{declcs}
+% Example:
+% \begin{quote}
+% |A \stackbin[\text{and}]{}{+} B \stackrel[x]{!}{=} C|\\
+% $A \stackbin[\text{and}]{}{+} B \stackrel[x]{!}{=} C$
+% \end{quote}

+\NeedsTeXFormat{LaTeX2e}

+  [2006/12/02 v1.0 Adding subscript option to stackrel (HO)]
+%    \end{macrocode}
+%
+%    Given the original definition of \cs{stackrel} the addition
+%    of the optional argument is straightforward. If an argument
+%    is empty, then the corresponding sub- or superscript is
+%    suppressed.
+%
+%    Depending on the available resources (\eTeX, \pdfTeX)
+%    three methods are given for testing emptyness. All tests
+%    allow the hash to be used inside the arguments without
+%    doubling (for the unlikely case that someone wants to
+%    define macros with arguments).

+% \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/stackrel.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/oberdiek/stackrel.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 stackrel.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@{}}
+%   stackrel.sty & tex/latex/oberdiek/stackrel.sty\\
+%   stackrel.pdf & doc/latex/oberdiek/stackrel.pdf\\
+%   stackrel.dtx & source/latex/oberdiek/stackrel.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 stackrel.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 intension:
+% \begin{quote}
+%   \verb|latex \install=y\input{stackrel.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 stackrel.dtx
+%makeindex -s gind.ist stackrel.idx
+%pdflatex stackrel.dtx
+%makeindex -s gind.ist stackrel.idx
+%pdflatex stackrel.dtx
+%\end{verbatim}
+% \end{quote}
+%
+% \begin{History}
+%   \begin{Version}{2006/12/02 v1.0}
+%   \item
+%     First version.
+%   \end{Version}
+% \end{History}
+%
+% \PrintIndex
+%
+% \Finale
