+%
+% \begin{abstract}
+% This package provides \cs{centernot} that prints the symbol
+% \cs{not} on the following argument. Unlike \cs{not} the symbol
+% is horizontally centered.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{User interface}
+%
+% If a negotiated relational symbol is not available, \cs{not}
+% can be used to create the negotiated variant of the relational
+% symbol. The disadvantage of \cs{not} is that it is put at
+% a fixed location regardless of the width of the relational
+% symbol. Therefore \cs{centernot} takes an argument and
+% measures its width to achieve a better placement of the
+% symbol \cs{not}.
+% Examples:
+% \begin{quote}
+% \begin{tabular}{@{}cccl@{}}
+% Symbol & \cs{not} & \cs{centernot} &\\
+% \hline
+% |=| & $\not=$ & $\centernot=$ & \textit{(definition)}\\
+% \cs{parallel} & $\not\parallel$ & $\centernot\parallel$\\
+% \cs{longrightarrow} &
+% $\not\longrightarrow$ & $\centernot\longrightarrow$
+% \end{tabular}
+% \end{quote}

+% \section{Implementation}
+%
+% \begin{macrocode}
+%<*package>
+\NeedsTeXFormat{LaTeX2e}
+\ProvidesPackage{centernot}
+ [2006/12/02 v1.0 Centers the not symbol horizontally (HO)]
+% \end{macrocode}
+%
+% \noindent
+% \cs{not} is a \cs{mathrel} atom with zero width. It prints itself
+% outside its character box, similar to \cs{rlap}. The next
+% \cs{mathrel} symbol is then print on top of it. \TeX\ does not
+% add space between two \cs{mathrel} atoms. The following implementation
+% assumes that the math font is designed in such a way that the
+% position of \cs{not} fits well on the equal symbol.
+%
+% The blue boxes marks the character bounding boxes seen by \TeX:
+% \begin{quote}
+% \setlength{\fboxrule}{.8pt}
+% \setlength{\fboxsep}{.8pt}
+% \def\xbox#1{^^A
+% \begingroup
+% \large
+% \color{blue}%
+% \fbox{\color{black}\boldmath$#1$}^^A
+% \kern-2\fboxsep
+% \kern-2\fboxrule
+% \endgroup
+% }
+% \begin{tabular}{@{}c@{\qquad}c@{\qquad}c@{}}
+% |\not| & |=| & |\not=|\\
+% \xbox{\not} & \xbox{=} & \xbox{\not}\xbox{=}
+% \end{tabular}
+% \end{quote}
+% \begin{macro}{\centernot}
+% \cs{centernot} is not a symbol but a macro that takes
+% one argument. It measures the width of the argument
+% and places \cs{not} horizontally centered on that argument.
+% The result is a \cs{mathrel} atom.
+% \begin{macrocode}
+\newcommand*{\centernot}{%
+ \mathpalette\@centernot
+}
+\def\@centernot#1#2{%
+ \mathrel{%
+ \rlap{%
+ \settowidth\dimen@{$\m@th#1{#2}$}%
+ \kern.5\dimen@
+ \settowidth\dimen@{$\m@th#1=$}%
+ \kern-.5\dimen@
+ $\m@th#1\not$%
+ }%
+ {#2}%
+ }%

+% \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/centernot.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/oberdiek/centernot.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 centernot.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@{}}
+% centernot.sty & tex/latex/oberdiek/centernot.sty\\
+% centernot.pdf & doc/latex/oberdiek/centernot.pdf\\
+% centernot.dtx & source/latex/oberdiek/centernot.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 centernot.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{centernot.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 centernot.dtx
+%makeindex -s gind.ist centernot.idx
+%pdflatex centernot.dtx
+%makeindex -s gind.ist centernot.idx
+%pdflatex centernot.dtx
+%\end{verbatim}
+% \end{quote}
+%
+% \begin{History}
+% \begin{Version}{2006/12/02 v1.0}
+% \item
+% First version.
+% \end{Version}
+% \end{History}
