%
% \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}

% \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 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):

% 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{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}
