+# mleftright
+
+mleftright package for LaTeX
+
+
+TeX sets subformulas by \left and \right as inner formulas
+with additional surrounding spaces in some situations. This package
+provides \mleft and \mright that call \left and \right,
+but the delimiters will act as normal \mathopen and \mathclose
+delimiters without the additional space of an inner formula.

+% \TeX\ sets subformulas by \cs{left} and \cs{right} as inner formulas
+% with additional surrounding spaces in some situations. This package
+% provides \cs{mleft} and \cs{mright} that call \cs{left} and \cs{right},
+% but the delimiters will act as normal \cs{mathopen} and \cs{mathclose}
+% delimiters without the additional space of an inner formula.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Documentation}
+%
+% The package is a result of a thread in the newsgroup \textsf{comp.text.tex}
+% with the subject \textit{spacing after \cs{right}\texttt{)}
+% and before \cs{left}\texttt{)}} \cite{dave}.
+% The problem: \cs{left} and \cs{right} adjust the size of the
+% delimiters automatically. However, \TeX\ treats the whole expression
+% as inner formula. In some circumstances \TeX\ adds extra space
+% before or after an inner formula.
+% Example:
+% \begin{quote}
+%   \thinmuskip=1.5\thinmuskip
+%   \begin{tabular}{@{}l@{\quad$\Rightarrow$\quad}l@{}}
+%     |$\sin(x^2), x$|
+%     & $\sin(x^2), x$\\
+%     |$\sin\left(x^2\right), x$|
+%     & $\sin\left(x^2\right), x$\\
+%   ^^A  \multicolumn{1}{@{}r@{\quad$\Rightarrow$\quad}}{^^A
+%   ^^A    \itshape with exaggerated spacing^^A
+%   ^^A  }
+%   ^^A  & $\thinmuskip=4\thinmuskip
+%   ^^A    \sin\left(x^2\right){,}\mskip.25\thinmuskip x$\\
+%     |$\sin\mleft(x^2\mright), x$|
+%     & $\sin\mleft(x^2\mright), x$\\
+%   \end{tabular}\\*[.5ex]
+%   (\cs{mleft} and \cs{mright} are provided by this package.)
+% \end{quote}
+%
+% In the newsgroup Donald Arseneau answered with clever macros \cite{arseneau}:
+% \begin{quote}
+%\begin{verbatim}
+%\newcommand\lft{\mathopen{}\left}
+%\newcommand\rgt{\aftergroup\mathclose\aftergroup{\aftergroup}\right}
+%\end{verbatim}
+% \end{quote}
+% However one problem remains, a following subscript or superscript
+% is not applied to the right delimiter but the empty
+% \cs{mathclose}.
+% Thus Philipp Stephani provided an improvement \cite{stephani}:
+%\begin{quote}
+%\begin{verbatim}
+%\mathopen{} \mathclose{\left\| A^2 \right\|}_2
+%\end{verbatim}
+%\end{quote}
+% Heiko Oberdiek converted this into macro form \cite{oberdiek}:
+%\begin{quote}
+%\begin{verbatim}
+%\newcommand\lft{\mathopen{}\mathclose\bgroup\left}
+%\newcommand\rgt{\aftergroup\egroup\right}
+%\end{verbatim}
+%\end{quote}
+%
+% The package uses longer macro names \cs{mleft} and \cs{mright}
+% to avoid name clashes. Also it adds some checks for error conditions.
+%
+% \subsection{Use}
+%
+% \begin{declcs}{mleft}\meta{delimL} \dots\unkern\ \cs{mright}\meta{delimR}
+% \end{declcs}
+% Macros \cs{mleft} and \cs{mright} are used in the same way as
+% \cs{left} and \cs{right}. Also \cs{middle} can be used inbetween if
+% \eTeX\ is present.
+%
+% \begin{declcs}{mleftright}
+% \end{declcs}
+% Macro \cs{mleftright} redefines \cs{left} as \cs{mleft} and
+% \cs{right} as \cs{mright}. The redefinition is local to the group.
+%
+% \begin{declcs}{mleftrightrestore}
+% \end{declcs}
+% Macro \cs{mleftright} restores \cs{left} and \cs{right} with
+% the original meaning if they were previously redefined by
+% \cs{mleftright} (also locally).

+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{mleftright}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/mleftright/mleftright.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/mleftright/mleftright.pdf}] Documentation.
+% \end{description}
+%
+%
+% \paragraph{Bundle.} All the packages of the bundle `mleftright'
+% 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/mleftright.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{mleftright.tds.zip} in the
+% TDS tree (also known as \xfile{texmf} tree) of your choice.
+% Example (linux):
+% \begin{quote}
+%   |unzip mleftright.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 mleftright.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):

+% \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.
+%
+% \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{mleftright.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 mleftright.dtx
+%makeindex -s gind.ist mleftright.idx
+%pdflatex mleftright.dtx
+%makeindex -s gind.ist mleftright.idx
+%pdflatex mleftright.dtx
+%\end{verbatim}
+% \end{quote}
