-% Package \xpackage{infwarerr} defines the following set of commands,
-% given as pseudo regular expression:
-% \begin{quote}
-% \verb+\@(Package|Class)(Info|InfoNoLine|Warning|WarningNoLine|Error)+^^A
-% \kern-\rightmargin
-% \end{quote}
-% The first argument is the package or class in question. The second
-% argument contains the message text. \cs{MessageBreak} is supported.
-% In case of error messages, the third argument contains the help
-% text. Supported are \LaTeX's message texts \cs{@ehc}:
-% \begin{quote}
-% |Try typing <return> to proceed|\\
-% |If that doesn't work, type X <return> to quit.|
-% \end{quote}
-% and \cs{@ehd}:
-% \begin{quote}
-% |You're in trouble here. Try typing <return> to proceed|\\
-% |If that doesn't work, type X <return> to quit.|
-% \end{quote}
-%
-% The package is intended for macro writers that want to write
-% code that works for both \LaTeX\ and \plainTeX. If \LaTeX\ is
-% detected, then the macros of this package will only be wrappers
-% for \LaTeX's macros. Otherwise \LaTeX's macros will be mimicked
-% for use with \plainTeX.

-% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{infwarerr}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/infwarerr.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/infwarerr.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 infwarerr.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{infwarerr.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 infwarerr.dtx
-%makeindex -s gind.ist infwarerr.idx
-%pdflatex infwarerr.dtx
-%makeindex -s gind.ist infwarerr.idx
-%pdflatex infwarerr.dtx
