+% \maketitle
+%
+% \begin{abstract}
+% The package generates the suffix of English ordinal numbers.
+% It can be used with plain and \LaTeX\ formats.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Usage}
+%
+% \begin{declcs}{engord}\,\M{\LaTeX\ counter name}
+% \end{declcs}
+% It prints the value of the \LaTeX\ counter as English
+% ordinal number. It can be used in the same way as
+% \cs{arabic}, \cs{roman}, or \cs{alph}. The command is
+% not available in \plainTeX.
+%
+% \begin{declcs}{engordnumber}\,\M{any \TeX\ number}
+% \end{declcs}
+% It prints the number as English ordinal number.
+%
+% \begin{declcs}{engordletters}\,|{#1}|
+% \end{declcs}
+% This command formats the English ordinal letters
+% after the number. It defaults to \cs{textsuperscript}.
+%
+% \begin{declcs}{engorderror}\,|{#1}|
+% \end{declcs}
+% It can be redefined, if an other error handling is
+% wanted. The argument is a negative number or zero.
+%
+% \begin{declcs}{engordraisetrue}\\
+% \SpecialUsageIndex{\engordraisefalse}\cs{engordraisefalse}
+% \end{declcs}
+% These commands set the switch \cs{ifengordraise} that is
+% asked by the default \cs{engordletters} before raising the
+% ordinal letters.
+%
+% \subsection{Package options}
+%
+% \begin{description}
+% \item[\xoption{normal}:] \cs{engordraisefalse}
+% \item[\xoption{raise}:] \cs{engordraisetrue}
+% \end{description}
+% Default is \xoption{raise}.
+%
+% \subsection{Examples}
+%
+% \begin{itemize}
+% \item
+% |\usepackage[normal]{engord}|\\
+% \begin{tabular}{@{}l@{ $\rightarrow$ }l@{}}
+% |\engordnumber{1}| & 1st\\
+% |\engordnumber{12}| & 12th\\
+% |\engordnumber{123}| & 123rd\\
+% |\engord{page}| & 1st (if page has the value of one)\\
+% \multicolumn{2}{@{}l}{\cs{engordraisetrue}}\\
+% |\engordnumber{12}| & 12\textsuperscript{th}
+% \end{tabular}
+% \item
+% The default output of a counter can be redefined:
+% \begin{quote}
+% |\newcounter{mycounter}|\\
+% |\renewcommand{\theengcounter}{\engord{mycounter}}|
+% \end{quote}
+% \item
+% Because the implementation of \cs{engord} and \cs{engordnumber}
+% is kept expandable, these commands can be used to make
+% command names with an appropriate definition of
+% \cs{engordletters}:
+% \begin{quote}
+% |\renewcommand*{\engordletters}[1]{#1}|\\
+% |\@namedef{My\engordnumber{3}Command}{...}|
+% \end{quote}
+% This generates the command name `\cs{My4rdCommand}'.
+% Since version 1.2 the redefinition can be dropped if
+% the letters are not raised.
+% \item
+% If the letters should not be raised, use \LaTeX\ package
+% option \xoption{normal} or use
+% \begin{quote}
+% \cs{engordraisefalse}
+% \end{quote}
+% Also \cs{engordletters} could be redefined for this purpose:
+% \begin{quote}
+% |\renewcommand*{\engordletters}[1]{#1}|
+% \end{quote}
+% \end{itemize}

+% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\url{http://ctan.org/pkg/engord}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/oberdiek/engord.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/oberdiek/engord.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[\CTAN{install/macros/latex/contrib/oberdiek.tds.zip}]
+% \end{description}
+% \emph{TDS} refers to the standard ``A Directory Structure
+% for \TeX\ Files'' (\CTAN{tds/tds.pdf}). 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}
+%
+% \paragraph{Script installation.}
+% Check the directory \xfile{TDS:scripts/oberdiek/} for
+% scripts that need further installation steps.
+% Package \xpackage{attachfile2} comes with the Perl script
+% \xfile{pdfatfi.pl} that should be installed in such a way
+% that it can be called as \texttt{pdfatfi}.
+% Example (linux):
+% \begin{quote}
+% |chmod +x scripts/oberdiek/pdfatfi.pl|\\
+% |cp scripts/oberdiek/pdfatfi.pl /usr/local/bin/|
+% \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 engord.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}
+% \def\t{^^A
+% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}}
+% engord.sty & tex/generic/oberdiek/engord.sty\\

+% \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
+% (\teTeX, \mikTeX, \dots) relies on file name 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 engord.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 intention:
+% \begin{quote}
+% \verb|latex \let\install=y\input{engord.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 engord.dtx
+%makeindex -s gind.ist engord.idx
+%pdflatex engord.dtx
+%makeindex -s gind.ist engord.idx
+%pdflatex engord.dtx
+%\end{verbatim}
+% \end{quote}
+%
+% \section{Catalogue}
+%
+% The following XML file can be used as source for the
+% \href{http://mirror.ctan.org/help/Catalogue/catalogue.html}{\TeX\ Catalogue}.
+% The elements \texttt{caption} and \texttt{description} are imported
+% from the original XML file from the Catalogue.
+% The name of the XML file in the Catalogue is \xfile{engord.xml}.
+% \begin{macrocode}
