% \section{Documentation}
%
% Sometimes an equation is just a little to large to fit in the
% line. And breaking the equation across lines might be worse
% than downscaling the equation. This package implements this
% for the environments \env{gather} and \env{gather*} of
% package \xpackage{amsmath}. That package already measures
% the equations and simplifies the implementation of \xpackage{resizegather}
% that only needs to hook into \xpackage{amsmath}'s code to add
% the resizing feature.
%
% Resized equations are recorded in the \xext{log} file
% for small exceeds (default setting is smaller than five percent).
% Otherwise a warning is given.
%
% Also environments \env{equation} and \env{displaymath}
% are supported by redefining them using \env{gather}
% and \env{gather*}.
%
% \cs{[} and \cs{]} are not supported, because these macros
% are not in environment form that is required for
% \xpackage{amsmath}. The environment body is collected
% first to be able to process the body twice for measuring
% first.
%
% Also the environments using alignments are not supported.
% If a single equation line would be resized, the alignment
% would get lost. And resizing all equations of the alignment
% does not seem appropriate either.
%
% \subsection{Options}
%
% \begin{description}
% \item[\xoption{warningthreshold}:]
%   Print a warning if the original equation line exceeds
%   its available width by the given fraction.
%   Default is |0.05|: A warning is given if the equation
%   is too large by five percent.
%   Otherwise the exceed is recorded in the \xext{log} file
%   only.
% \end{description}
% The next options are boolean options. They are enabled
% by value |true| or if no value is given. They are switched
% off by value |false|.
% \begin{description}
% \item[\xoption{enable}:] The resize feature is active (default).
% \item[\xoption{disable}:] The complementary option for \xoption{enable},
%  added for convenience: |disable| (or |disable=true|) is the same
%  as |enable=false|.
% \item[\xoption{equations}:]
%   \LaTeX\ environments \textsf{equation} and \textsf{displaymath}
%   environments are redefined. These equations
%   are now using environment \env{gather} and
%   \env{gather*}. This is the default.
% \end{description}
% The following table shows additional options if you
% want to have finer control for the redefined
% environments:
% \begin{quote}
% \def\unchanged{\textit{unchanged}}
% \def\notprovided{\textit{not provided}}
% \begin{tabular}{l|ll}
% &amp;\multicolumn{2}{c}{Environments}\\
% Option &amp; \env{equation} &amp; \env{displaymath}\\
% \hline
% \xoption{equations} &amp; \env{gather} &amp; \env{gather*}\\
% \xoption{equation} &amp; \env{gather} &amp; \unchanged\\
% \xoption{displaymath} &amp; \unchanged &amp; \env{gather*}\\
% \end{tabular}
% \end{quote}
% If such an option is switched off, the original meaning
% of the affected environments is restored.
%
% Options are evaluated in the following order:
% \begin{enumerate}
% \item
%  Configuration file \xfile{resizegather.cfg} using \cs{resizegathersetup}
%  if the file exists.
%  \item
%  Package options given for \cs{usepackage}.
%  \item
%  Later calls of \cs{resizegathersetup}.
% \end{enumerate}
% \begin{declcs}{resizegathersetup}\M{option list}
% \end{declcs}
% The options are key value options. Boolean options are enabled by
% default (without value) or by using the explicit value \texttt{true}.
% Value \texttt{false} disable the option.
%
% \subsection{Options for packages \xpackage{amsmath} or \xpackage{graphics}}
%
% The package loads the package \xpackage{amsmath} because is internally
% measures the equations first. Thus this package hooks into this code
% in order to resize the equations if they are too large.
% The resizing itself is done by \cs{resizebox} of package \xpackage{graphics}.
% If you need special options for these packages, just load them first or
% use global options when appropriate. Example:
% \begin{quote}
%\begin{verbatim}
%\usepackage[dvipdfm]{graphicx}% or graphics
%\usepackage[fleqn]{amsmath}
%\usepackage{resizegather}
%\end{verbatim}
%\end{quote}

%
%
% \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 resizegather.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{resizegather.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 resizegather.dtx
%makeindex -s gind.ist resizegather.idx
%pdflatex resizegather.dtx
%makeindex -s gind.ist resizegather.idx
%pdflatex resizegather.dtx
%\end{verbatim}
% \end{quote}
%
% \section{Acknowledgement}

% \begin{description}
% \item[Dieter Jurzitza:]
% He wanted the resizing feature at the \TeX\ table
% in Karlsruhe of December 2009. Thus this package is a kind of
% Christmas present.
