+Generic TeX Bundle : tracklang v1.0
+
+Last Modified : 2014-09-29
+
+Author : Nicola Talbot
+
+LaTeX usage: \usepackage{tracklang}
+
+TeX usage: \input tracklang
+
+LaTeX code is in tracklang.sty. Generic TeX code is in
+tracklang.tex (category code of @ must be 11 on input).
+
+The tracklang package is provided for package developers who want a
+simple interface to find out which languages the user has requested
+through packages such as babel and polyglossia. *This package
+doesn't provide any translations.* Its purpose is simply to track
+which languages have been requested by the user.

+%The \styfmt{tracklang} package is provided for package developers
+%who want a simple interface to find out which languages the user has
+%requested through packages such as \sty{babel} and
+%\sty{polyglossia}. \emph{This package doesn't provide any
+%translations.}
+%Its purpose is simply to track which languages have been requested by the
+%user. Generic \TeX\ code is in \texttt{tracklang.tex} for
+%non-\LaTeX\ users (category code of \texttt{@} must be 11 on input).
+%\end{abstract}

+%\tableofcontents
+%
+%\section{Introduction}
+%\label{sec:intro}
+%
+%When I'm developing a package that provides multilingual support
+%(for example, \styfmt{glossaries}) it's cumbersome trying to work out
+%if the user has requested translations for fixed text. This usually
+%involves checking if \sty{babel} or \sty{ngerman} or
+%\sty{translator} or \sty{polyglossia} has been loaded and, if so,
+%what language settings have been used. The result can be a tangled
+%mass of conditional code. The alternative is to tell users to add
+%the language as a~document class option, which they may or may not
+%want to do, or to tell them to supply the language settings to every
+%package they load that provides multilingual support, which users
+%are even less likely to want to do.
+%
+%The \styfmt{tracklang} package tries to neaten this up by working out
+%as much of this information as possible for you and providing a
+%command that iterates through the loaded languages. This way, you
+%can just iterate through the list of tracked languages and, for each
+%language, either define the translations or warn the user that
+%there's no translation for that language.
+%
+%This package works best with \sty{ngerman} and recent versions of \sty{babel},
+%and next best when the language options are specified
+%in the document class option list. It works fairly well with
+%\sty{translator} but will additionally assume the root language was
+%also requested when a dialect is specified. So, for example,
+%\begin{verbatim}
+%\usepackage[british]{translator}
+%\usepackage{tracklang}
+%\end{verbatim}
+%is equivalent to
+%\begin{verbatim}
+%\usepackage[british]{translator}
+%\usepackage[english,british]{tracklang}
+%\end{verbatim}
+%This means that \ics{ForEachTrackedDialect} will iterate
+%through the list ``english,british'' instead of just
+%``british''.
+%
+%Unfortunately I can't work out how to pick up the language variant
+%from \sty{polyglossia}, so only the root languages are detected,
+%which is suboptimal but at least provides some information.
+%
+%If the \sty{ngerman} package has been loaded, \styfmt{tracklang}
+%sets the root language to ``german'' and the dialect to ``ngerman''.
+%
+%Section~\ref{sec:user} is for package writers who want to
+%add multilingual support to their package and need to know which
+%settings the user has requested through language packages like
+%\sty{babel}. Section~\ref{sec:langsty} is for
+%developers of language definition packages who want to help other
+%package writers to detect what languages have been requested.
+%Section~\ref{sec:plain} provides a plain \TeX\ example.
+%
+%\section{Detecting the User's Requested Languages}
+%\label{sec:user}
+%
+%The \styfmt{tracklang} package tries to track the loaded languages and
+%the option names used to identify those languages. For want of a better
+%term, the language option names are referred to as dialects even if
+%they're only a synonym for the language rather than an actual
+%dialect. For example, if the user
+%has requested \texttt{british}, the root language label is
+%\texttt{english} and the dialect is \texttt{british}, whereas if the
+%user requested \texttt{UKenglish}, the root language label is
+%\texttt{english} and the dialect is \texttt{UKenglish}.
+%
+%In addition to the root language label and the dialect identifier,
+%most of the language options also have corresponding ISO codes. In
+%most cases there is an ISO~639-1 or an ISO~639-2 code (or both), and in some
+%cases there is an ISO~3166-1 code identifying the dialect region.
+%
+%When \styfmt{tracklang} is loaded, it first attempts to find the
+%language options through the package options supplied to
+%\styfmt{tracklang}. This means that any languages that have been
+%supplied in the document class options should get identified.
+%If no languages have been supplied in this way, \styfmt{tracklang} then
+%attempts to identify any \sty{babel} language options and failing that
+%it will try the \sty{translator} language options. It will then
+%check if \sty{ngerman} or \sty{polyglossia} have been loaded.
+%
+%Each identified language and dialect is added to the \emph{tracked
+%language} and \emph{tracked dialect} lists. Note that the tracked
+%language and tracked dialect are labels rather than proper nouns.
+%If a~dialect label is identical to its root language label, the
+%label will appear in both lists.
+%
+%You can check whether or not any languages have been detected using:
+%\begin{definition}
+%\ics{AnyTrackedLanguages}\marg{true part}\marg{false part}
+%\end{definition}
+%This will do \meta{true part} if one or more languages have been
+%detected otherwise it will do \meta{false part}. (Each detected
+%dialect will automatically have the root language label added
+%to the tracked language list, if it's not already present.)
+%
+%You can iterate through each tracked dialect using:
+%\begin{definition}
+%\ics{ForEachTrackedDialect}\marg{cs}\marg{code}
+%\end{definition}
+%At the start of each iteration, this sets \meta{cs} to the
+%tracked dialect and does \meta{code}.
+%
+%You can iterate through each tracked language using:
+%\begin{definition}
+%\ics{ForEachTrackedLanguage}\marg{cs}\marg{code}
+%\end{definition}
+%At the start of each iteration, this sets \meta{cs} to the
+%tracked language and does \meta{code}.
+%
+%You can test if a root language has been detected using:
+%\begin{definition}
+%\ics{IfTrackedLanguage}\marg{label}\marg{true part}\marg{false part}
+%\end{definition}
+%where \meta{label} is the language label. If
+%true, this does \meta{true part} otherwise it does \meta{false
+%part}.
+%
+%You can test if a particular dialect has been detected using:
+%\begin{definition}
+%\ics{IfTrackedDialect}\marg{label}\marg{true part}\marg{false part}
+%\end{definition}
+%where \meta{label} is the dialect label. If the root language was explicitly specified, then it will
+%also be detected as a dialect.
+%
+%For example:
+%\begin{verbatim}
+%\documentclass[british,dutch]{article}
+%
+%\usepackage{tracklang}
+%
+%\begin{document}
+%``english'' \IfTrackedDialect{english}{has}{hasn't} been specified.
+%
+%``british'' \IfTrackedDialect{british}{has}{hasn't} been specified.
+%
+%``flemish'' \IfTrackedDialect{flemish}{has}{hasn't} been specified.
+%
+%``dutch'' \IfTrackedDialect{dutch}{has}{hasn't} been specified.
+%
+%``english'' or an English variant
+%\IfTrackedLanguage{english}{has}{hasn't} been specified.
+%
+%\end{document}
+%\end{verbatim}
+%This produces:
+%\begin{quote}
+%``english'' hasn't been specified.
+%
+%``british'' has been specified.
+%
+%``flemish'' hasn't been specified.
+%
+%``dutch'' has been specified.
+%
+%``english'' or an English variant has been specified.
+%\end{quote}
+%
+%You can find the root language label for a given tracked dialect
+%using:
+%\begin{definition}
+%\ics{TrackedLanguageFromDialect}\marg{dialect}
+%\end{definition}
+%If \meta{dialect} hasn't been defined this does nothing otherwise it
+%expands to the root language label.
+%
+%You can find the tracked dialects from a given root language
+%using:
+%\begin{definition}
+%\ics{TrackedDialectsFromLanguage}\marg{root language label}
+%\end{definition}
+%This will expand to a~comma-separated list of dialect labels
+%if the root language label has been defined, otherwise it
+%does nothing.
+%
+%
+%You can test if a language (or dialect) has a corresponding ISO code using:
+%\begin{definition}
+%\ics{IfTrackedLanguageHasIsoCode}\marg{code
+%type}\marg{label}\marg{true part}\marg{false part}
+%\end{definition}
+%where \meta{code type} is the type of ISO code (for example,
+%\texttt{639-1} for root languages or \texttt{3166-1} for regional
+%dialects), and \meta{label} is the language or dialect label.
+%
+%Alternatively, you can test if a particular ISO code has been
+%defined using:
+%\begin{definition}
+%\ics{IfTrackedIsoCode}\marg{code type}\marg{code}\marg{true
+%part}\marg{false part}
+%\end{definition}
+%where \meta{code type} is again the type of ISO code (for example,
+%\texttt{639-1} or \texttt{3166-1}), and \meta{code} is the
+%particular code (for example, \texttt{en} for ISO 639-1 or
+%\texttt{GB} for ISO 3166-1).
+%
+%You can fetch the language (or dialect) label associated with a
+%given ISO code using:
+%\begin{definition}
+%\ics{TrackedLanguageFromIsoCode}\marg{code type}\marg{code}
+%\end{definition}
+%This does nothing if the given \meta{code} for the given ISO
+%\meta{code type} has not been defined, otherwise it expands
+%a~comma-separated list of language or dialect labels.
+%
+%You can fetch the ISO code for a given code type using:
+%\begin{definition}
+%\ics{TrackedIsoCodeFromLanguage}\marg{code type}\marg{label}
+%\end{definition}
+%where \meta{label} is the language or dialect label and \meta{code
+%type} is the ISO code type (for example, \texttt{639-1} or
+%\texttt{3166-1}). Unlike \ics{TrackedLanguageFromIsoCode}, this
+%command only expands to a single label rather than a~comma-separated
+%list.
+%
+%The above commands do nothing in the event of an unknown code or
+%code type,
+%so if you accidentally get the wrong code type, you won't get an error.
+%If you're unsure of the code type, you can use the following commands:
+%\begin{definition}
+%\ics{TwoLetterIsoCountryCode}
+%\end{definition}
+%This expands to 3166-1 and is used for the two-letter country codes.
+%
+%\begin{definition}
+%\ics{TwoLetterIsoLanguageCode}
+%\end{definition}
+%This expands to 639-1 and is used for the two-letter root language codes.
+%
+%\begin{definition}
+%\ics{ThreeLetterIsoLanguageCode}
+%\end{definition}
+%This expands to 639-2 and is used for the three-letter root language
+%codes.
+%
+%For example:
+%\begin{verbatim}
+%\documentclass[british,francais,american,canadian,canadien,dutch]{article}
+%
+%\usepackage{tracklang}
+%
+%\begin{document}
+%
+%Languages: \ForEachTrackedLanguage{\ThisLanguage}{\ThisLanguage\space
+%(ISO \TwoLetterIsoLanguageCode:
+%``\TrackedIsoCodeFromLanguage{\TwoLetterIsoLanguageCode}{\ThisLanguage}''). }
+%
+%Dialects: \ForEachTrackedDialect{\ThisDialect}{\ThisDialect\space
+%(\IfTrackedLanguageHasIsoCode{\TwoLetterIsoCountryCode}{\ThisDialect}%
+% {ISO \TwoLetterIsoCountryCode:
+% ``\TrackedIsoCodeFromLanguage{\TwoLetterIsoCountryCode}{\ThisDialect}''}%
+% {no specific region};
+%root: \TrackedLanguageFromDialect{\ThisDialect}). }
+%
+%Language for ISO \TwoLetterIsoCountryCode\ ``GB'':
+%\TrackedLanguageFromIsoCode{\TwoLetterIsoCountryCode}{GB}.
+%
+%Language for ISO \TwoLetterIsoCountryCode\ ``CA'':
+%\TrackedLanguageFromIsoCode{\TwoLetterIsoCountryCode}{CA}.
+%
+%Country ISO \TwoLetterIsoCountryCode\ code for ``canadian'':
+%\TrackedIsoCodeFromLanguage{\TwoLetterIsoCountryCode}{canadian}.
+%
+%\end{document}
+%\end{verbatim}
+%This produces:
+%\begin{quote}
+%Languages: english (ISO 639-1: ``en''). french (ISO 639-1: ``fr'').
+%dutch (ISO 639-1: ``nl'').
+%
+%Dialects: american (ISO 3166-1: ``US''; root: english).

+%
+%\end{quote}
+%
+%Most packages that implement multilingual support have a~set of
+%language definition files for each supported language or dialect.
+%It may be that only the root language is needed, if there are no
+%variations between that language's dialect (for the purposes of that
+%package), or it may be that separate definition files are required
+%for each dialect. However it can be awkward trying to map the
+%requested dialect or language label to the file name. Should, say,
+%the file containing the French code be called
+%\meta{prefix}\texttt{-french-}\meta{suffix} or
+%\meta{prefix}\texttt{-frenchb-}\meta{suffix} or
+%\meta{prefix}\texttt{-francais-}\meta{suffix}?
+%Should, say, the file containing the British English code be called
+%\meta{prefix}\texttt{-british-}\meta{suffix} or
+%\meta{prefix}\texttt{-UKenglish-}\meta{suffix}?
+%If you want to modularise the language support for your package so
+%that each language module has a different maintainer will the
+%maintainers know what tag to use for their language?
+%
+%To help with this, \styfmt{tracklang} provides:
+%\begin{definition}
+%\ics{IfTrackedLanguageFileExists}\marg{label}\meta{prefix}\marg{suffix}\marg{true part}\marg{false part}
+%\end{definition}
+%This attempts to find the file called
+%\meta{prefix}\meta{tag}\meta{suffix} where \meta{tag} is determined
+%from \meta{label}. If the file is found
+%\begin{definition}
+%\ics{CurrentTrackedTag}
+%\end{definition}
+%is set to \meta{tag} and \meta{true part} is done, otherwise
+%\meta{false part} is done.
+%
+%The \meta{tag} is determined as follows:
+%\begin{enumerate}
+% \item If no dialect with the given label has been
+% detected, the condition evaluates to \emph{false} and
+% \ics{CurrentTrackedTag} is empty.
+%
+% \item If \meta{label} has an ISO~3166-1 code, then
+%\begin{definition}
+%\ics{CurrentTrackedRegion}
+%\end{definition}
+% is set to that code otherwise it's empty.
+%
+% \item If the file \meta{prefix}\meta{label}\meta{suffix} exists,
+% \meta{tag} (\ics{CurrentTrackedTag}) is just \meta{label} and the
+% condition evaluates to \emph{true}.
+%
+% \item The root language label is obtained and stored in
+%\begin{definition}
+%\ics{CurrentTrackedLanguage}
+%\end{definition}
+% (This may or may not be the same as the original dialect
+% \meta{label}.)
+%
+% \item If the root language has an ISO~639-1 code, this code is
+% fetched and stored in
+%\begin{definition}
+%\ics{CurrentTrackedIsoCode}
+%\end{definition}
+% If the root language doesn't have an ISO~639-1 code, but does
+% have an ISO~639-2 code, then this code is fetched and stored
+% in \ics{CurrentTrackedIsoCode}.
+%
+% \item If is no ISO~639-1 and no ISO~636-2 code:
+%
+% \begin{enumerate}
+% \item If there is also no ISO~3166-1 code (\ics{CurrentTrackedRegion}
+% is empty), then \meta{tag} (\ics{CurrentTrackedTag}) is set to the
+% root language (\ics{CurrentTrackedLanguage}). If the file
+% \meta{prefix}\meta{tag}\meta{suffix} exists, the condition will evaluate to
+% \emph{true} otherwise it will evaluate to \emph{false}.
+%
+% \item If there is an ISO~3166-1 code, then \meta{tag}
+% (\ics{CurrentTrackedTag}) will be set to \ics{CurrentTrackedRegion}
+% and if the file \meta{prefix}\meta{tag}\meta{suffix} exists,
+% the condition will evaluate to \emph{true} otherwise it will evaluate
+% to \emph{false}.
+% \end{enumerate}
+%
+% \item If \ics{CurrentTrackedRegion} is empty (no ISO~3166-1 code)
+% then \meta{tag} (\ics{CurrentTrackedTag}) is set to just
+% \ics{CurrentTrackedIsoCode} and if the file
+% \meta{prefix}\marg{tag}\meta{suffix} exists, the condition will
+% evaluate to \emph{true}. If the file doesn't exist and
+% \ics{CurrentTrackedIsoCode} was set to the ISO~639-1 code, then
+% the test will be repeated with the ISO~639-2 code. If that test
+% also fails, then the condition evaluates to \emph{false}.
+%
+% \item\label{itm:lang-country} The \meta{tag} (\ics{CurrentTrackedTag}) is then set to
+%\begin{verbatim}
+%\CurrentTrackedIsoCode-\CurrentTrackedRegion
+%\end{verbatim}
+% and if the file \meta{prefix}\meta{tag}\meta{suffix} exists,
+% the condition evaluates to \emph{true}.
+%
+% \item The \meta{tag} (\ics{CurrentTrackedTag}) is then set to
+% just \ics{CurrentTrackedIsoCode}, and if the file
+% \meta{prefix}\meta{tag}\meta{suffix} exists,
+% the condition evaluates to \emph{true}. If the file doesn't exist
+% and \ics{CurrentTrackedIsoCode} is set to the ISO~636-1 code and
+% the language also has an ISO~636-2 code, then set
+% \ics{CurrentTrackedIsoCode} to the ISO~636-2 code and go back to
+% step~\ref{itm:lang-country}.
+%
+% \item If there is an ISO~3166-1 code, the
+% \meta{tag} (\ics{CurrentTrackedTag}) is then set to
+% \ics{CurrentTrackedRegion},
+% and if the file \meta{prefix}\meta{tag}\meta{suffix} exists,
+% the condition evaluates to \emph{true}.
+%
+% \item Finally, the \meta{tag} (\ics{CurrentTrackedTag}) is set to
+% the root language label and if the file
+% \meta{prefix}\meta{tag}\meta{suffix} exist the condition
+% evaluates to \emph{true} otherwise it evaluates to \emph{false}.
+%
+%\end{enumerate}
+%
+%The \ics{IfTrackedLanguageFileExists} command sets the following
+%commands which may be used within \meta{true part} or \meta{false
+%part}:
+%\begin{definition}
+%\ics{CurrentTrackedDialect}
+%\end{definition}
+%This command will always be set to the first argument of
+%\ics{IfTrackedLanguageFileExists}.
+%
+%\begin{definition}
+%\ics{CurrentTrackedTag}
+%\end{definition}
+%This command will be set to \meta{tag} if the file
+%\meta{prefix}\meta{tag}\meta{suffix} is found. If this command
+%is empty, then the dialect hasn't been detected. If the dialect
+%has been detected, but no file can be found, then
+%\ics{CurrentTrackedTag} is set to the final attempt at determining
+%\meta{tag}.
+%
+%\begin{definition}
+%\ics{CurrentTrackedLanguage}
+%\end{definition}
+%If the dialect hasn't been detected, this command will be empty,
+%otherwise it will expand to the root language label (which may
+%be the same as the dialect label).
+%
+%\begin{definition}
+%\ics{CurrentTrackedRegion}
+%\end{definition}
+%If the dialect hasn't been detected, this command will be empty.
+%If the dialect has been assigned an ISO~3166-1 code,
+%\ics{CurrentTrackedRegion} will expand to that code, otherwise it
+%will be empty.
+%
+%\begin{definition}
+%\ics{CurrentTrackedIsoCode}
+%\end{definition}
+%If the dialect hasn't been detected, this command will be empty.
+%Otherwise it may be empty or it may expand to either the
+%ISO~639-1 or ISO~639-2 code (see above).
+%
+%For example:
+%\begin{verbatim}
+%\AnyTrackedLanguages
+%{%
+% \ForEachTrackedDialect{\ThisDialect}%
+% {% try to load the language file for this dialect
+% \IfTrackedLanguageFileExists{\ThisDialect}%
+% {mypackage-}% file prefix

+% {% not found
+% \PackageWarning{mypackage}{No support for language
+% `\ThisDialect'}%

+%{% no languages detected so use defaults

+%
+%The examples in this section illustrate the above commands.
+%
+%\subsubsection{animals.sty}
+%\label{sec:animals}
+%
+%This example is for a trivial package called \sty{animals.sty}
+%that defines three textual commands: \cs{catname}, \cs{dogname}
+%and \cs{ladybirdname}. The default values are: ``cat'', ``dog'' and
+%``bishy-barney-bee''.\footnote{Thass Broad Norfolk, my bewties
+%\texttt{:-P}}
+%
+%The supported languages are defined in files
+%with the prefix \texttt{animals-} and the suffix \texttt{.ldf}.
+%
+%Here's the code for the \texttt{animals.sty}:
+%\begin{verbatim}
+%\NeedsTeXFormat{LaTeX2e}
+%\ProvidesPackage{animals}
+%
+%\RequirePackage{tracklang}
+%
+%\newcommand\catname{cat}
+%\newcommand\dogname{dog}
+%\newcommand\ladybirdname{bishy-barney-bee}
+%
+%\AnyTrackedLanguages
+%{%
+% \ForEachTrackedDialect{\this@dialect}{%
+% \IfTrackedLanguageFileExists{\this@dialect}%
+% {animals-}% prefix
+% {.ldf}%
+% {%
+% \PackageInfo{tracklang}{Loading `animals-\CurrentTrackedTag.ldf'
+% for language `\this@dialect'}%
+% \input{animals-\CurrentTrackedTag.ldf}%
+% }%
+% {%
+% \PackageWarning{animals}%
+% {No support for language `\this@dialect'}%
+% }%
+% }%
+%}
+%{% no tracked languages, default already set up
+%}
+%
+%\endinput
+%\end{verbatim}
+%The \texttt{animals-english.ldf} file contains:
+%\begin{verbatim}
+%\providecommand*{\englishanimals}{%
+% \renewcommand*{\catname}{cat}%
+% \renewcommand*{\dogname}{dog}%
+% \renewcommand*{\ladybirdname}{bishy-barney-bee}%
+%}
+%\englishanimals
+%\end{verbatim}
+%The \texttt{animals-en-GB.ldf} file contains:
+%\begin{verbatim}
+%\input{animals-english.ldf}
+%
+%\providecommand*{\englishGBanimals}{%
+% \englishanimals
+% \renewcommand*{\ladybirdname}{ladybird}%
+%}
+%\englishGBanimals
+%\end{verbatim}
+%The \texttt{animals-en-US.ldf} file contains:
+%\begin{verbatim}
+%\input{animals-english.ldf}
+%
+%\providecommand*{\englishUSanimals}{%
+% \englishanimals
+% \renewcommand*{\ladybirdname}{ladybug}%
+%}
+%\englishUSanimals
+%\end{verbatim}
+%
+%This simple example doesn't try to use \sty{babel} or \sty{polyglossia}'s
+%\cs{captions}\meta{language} mechanism, which means that if any
+%users need to switch language part way through the document they
+%will have to use \cs{englishanimals}, \cs{englishGBanimals} or
+%\cs{englishUSanimals} to redefine the fixed names provided by this
+%package.
+%
+%The other drawback to this package is that if the user
+%requests both \texttt{british} (or \texttt{UKenglish}) and
+%\texttt{american} (or \texttt{USenglish}), then the
+%\texttt{animals-english.ldf} file is loaded twice, once by
+%\texttt{animals-en-GB.ldf} and once by \texttt{animals-en-US.ldf}.
+%This redundant input can be avoided by implementing a mechanism
+%similar to \cs{RequirePackage}. The example package below,
+%\texttt{animals2.sty} adds the following definitions:
+%\begin{verbatim}
+%\newcommand*{\RequireAnimalsLang}[1]{%
+% \@ifundefined{ver@animals2-#1.ldf}{\input{animals2-#1.ldf}}{}%
+%}
+%
+%\newcommand*{\ProvidesAnimalsLang}[1]{%
+% \ProvidesFile{animals2-#1.ldf}%
+%}
+%\end{verbatim}
+%Each \texttt{.ldf} file should now identify itself with
+%\cs{ProvidesAnimalsLang} so it can then be loaded with
+%\cs{RequireAnimalsLang}. The complete code for \texttt{animals2.sty}
+%is now:
+%\begin{verbatim}
+%\NeedsTeXFormat{LaTeX2e}
+%\ProvidesPackage{animals2}
+%
+%\RequirePackage{tracklang}
+%
+%\newcommand\catname{cat}
+%\newcommand\dogname{dog}
+%\newcommand\ladybirdname{bishy-barney-bee}
+%
+%\newcommand*{\RequireAnimalsLang}[1]{%
+% \@ifundefined{ver@animals2-#1.ldf}{\input{animals2-#1.ldf}}{}%
+%}
+%
+%\newcommand*{\ProvidesAnimalsLang}[1]{%
+% \ProvidesFile{animals2-#1.ldf}%

+%

+% {%
+% \PackageWarning{animals2}%
+% {No support for language `\this@dialect'}%
+% }%
+% }%
+%}
+%{% no tracked languages, default already set up
+%}
+%
+%\endinput
+%\end{verbatim}
+%The \texttt{animals2-english.ldf} file is now:
+%\begin{verbatim}
+%\ProvidesAnimalsLang{english}
+%
+%\providecommand*{\englishanimals}{%
+% \renewcommand*{\catname}{cat}%
+% \renewcommand*{\dogname}{dog}%
+% \renewcommand*{\ladybirdname}{bishy-barney-bee}%
+%}
+%\englishanimals
+%\end{verbatim}
+%The \texttt{animals2-en-GB.ldf} file is now:
+%\begin{verbatim}
+%\ProvidesAnimalsLang{en-GB}
+%
+%\RequireAnimalsLang{english}%
+%
+%\providecommand*{\englishGBanimals}{%
+% \englishanimals
+% \renewcommand*{\ladybirdname}{ladybird}%
+%}
+%\englishGBanimals
+%\end{verbatim}
+%The \texttt{animals2-en-US.ldf} file is now:
+%\begin{verbatim}
+%\ProvidesAnimalsLang{en-US}
+%
+%\RequireAnimalsLang{english}%
+%
+%\providecommand*{\englishUSanimals}{%
+% \englishanimals
+% \renewcommand*{\ladybirdname}{ladybug}%
+%}
+%
+%\englishUSanimals
+%\end{verbatim}
+%Here's a sample document:
+%\begin{verbatim}
+%\documentclass[british,american,a4paper]{article}
+%
+%\usepackage{animals2}
+%
+%\begin{document}
+%
+%\englishGBanimals
+%
+%\catname.
+%\dogname.
+%\ladybirdname.
+%
+%\englishUSanimals
+%
+%\catname.
+%\dogname.
+%\ladybirdname.
+%
+%\end{document}
+%\end{verbatim}
+%The transcript includes:
+%\begin{verbatim}
+%(./animals2.sty
+%(./tracklang.sty) (./animals2-en-US.ldf (./animals2-english.ldf))
+%(./animals2-en-GB.ldf))
+%\end{verbatim}
+%which shows that \texttt{animals2-english.ldf} is only input once.
+%
+%The next step is to integrate with \sty{babel} or
+%\sty{polyglossia}. Both these packages use
+%\cs{captions}\meta{language} to update fixed names whenever the
+%given \meta{language} is selected. With \sty{babel} the
+%\meta{language} setting is the dialect label (which may also be the
+%root language label). With \sty{polyglossia} \meta{language} is the
+%root language label, regardless of the selected variant.
+%
+%For example, if you load \sty{babel} using:
+%\begin{verbatim}
+%\usepackage[UKenglish]{babel}
+%\end{verbatim}
+%then \cs{captionsUKenglish} is defined but if you use:
+%\begin{verbatim}
+%\usepackage[british]{babel}
+%\end{verbatim}
+%then \cs{captionsbritish} is defined instead. If, however, you load
+%\sty{polyglossia} using:
+%\begin{verbatim}
+%\usepackage{polyglossia}
+%\setmainlanguage[variant=british]{english}
+%\end{verbatim}
+%then \cs{captionsenglish} is defined.
+%
+%This just requires a few minor modifications to the above example
+%package. Remember that the \texttt{.ldf} files are loaded within
+%\ics{IfTrackedLanguageFileExists}, which means that the dialect label
+%can be obtained from \ics{CurrentTrackedDialect}. To allow for the
+%possibility of loading a language file at some later date,
+%\ics{IfTrackedLanguageFile} can be moved to a new user command:
+%\begin{verbatim}
+%\newcommand*{\RequireAnimalsDialect}[1]{%
+% \IfTrackedLanguageFileExists{#1}%
+% {animals3-}% prefix
+% {.ldf}%
+% {%
+% \RequireAnimalsLang{\CurrentTrackedTag}%
+% }%
+% {%
+% \PackageWarning{animals3}%
+% {No support for language `#1'}%
+% }%
+%}
+%\end{verbatim}
+%Now \texttt{animals3-en-GB.ldf} and \texttt{animals3-en-US.ldf} can
+%use \ics{CurrentTrackedDialect} to add to the language captions mechanism.
+%The file \texttt{animals3-en-GB.ldf} contains:
+%\begin{verbatim}
+%\ProvidesAnimalsLang{en-GB}
+%
+%\RequireAnimalsLang{english}%
+%
+%\providecommand*{\englishGBanimals}{%
+% \englishanimals
+% \renewcommand*{\ladybirdname}{ladybird}%
+%}
+%
+%\englishGBanimals
+%
+%\@ifundefined{captions\CurrentTrackedDialect}
+%{%
+% \@ifundefined{captions\CurrentTrackedLanguage}{}%
+% {%
+% \expandafter\g@addto@macro
+% \csname captions\CurrentTrackedLanguage\endcsname{\englishGBanimals}%
+% }
+%}%
+%{%
+% \expandafter\g@addto@macro
+% \csname captions\CurrentTrackedDialect\endcsname{\englishGBanimals}%
+%}
+%\end{verbatim}
+%The file \texttt{animals3-en-GB.ldf} contains:
+%\begin{verbatim}
+%\ProvidesAnimalsLang{en-US}
+%
+%\RequireAnimalsLang{english}%
+%
+%\providecommand*{\englishUSanimals}{%
+% \englishanimals
+% \renewcommand*{\ladybirdname}{ladybug}%
+%}
+%
+%\englishUSanimals
+%
+%\@ifundefined{captions\CurrentTrackedDialect}%
+%{%
+% \@ifundefined{captions\CurrentTrackedLanguage}{}%
+% {%
+% \expandafter\g@addto@macro
+% \csname captions\CurrentTrackedLanguage\endcsname{\englishUSanimals}%
+% }
+%}%
+%{%
+% \expandafter\g@addto@macro
+% \csname captions\CurrentTrackedDialect\endcsname{\englishUSanimals}%
+%}
+%\end{verbatim}
+%The inner \cs{@ifundefined} check is required in case
+%\sty{polyglossia} has been loaded, although this causes some
+%redundancy as \cs{captionsenglish} now contains both
+%\cs{englishanimals} and \cs{englishGBanimals} (or
+%\cs{englishUSanimals}).
+%
+%The root language file \texttt{animals3-english.ldf} contains:
+%\begin{verbatim}
+%\ProvidesAnimalsLang{english}
+%
+%\providecommand*{\englishanimals}{%
+% \renewcommand*{\catname}{cat}%
+% \renewcommand*{\dogname}{dog}%
+% \renewcommand*{\ladybirdname}{bishy-barney-bee}%
+%}
+%
+%\englishanimals
+%
+%\@ifundefined{captionsenglish}%
+%{%
+% \@ifundefined{captions\CurrentTrackedDialect}{}%
+% {%
+% \expandafter\g@addto@macro
+% \csname captions\CurrentTrackedDialect\endcsname{\englishanimals}%
+% }
+%}%
+%{%
+% \g@addto@macro\captionsenglish{\englishanimals}%
+%}
+%\end{verbatim}
+%The additional \cs{@ifundefined} check ensures that the package
+%will work with other English dialects (although it may not produce
+%the correct translations for the given region). You'll have to
+%decide on the most appropriate default translations for the
+%root language.
+%
+%The complete code for the \texttt{animals3.sty} package is as
+%follows:

+%
+%Here's sample document that uses this package with \sty{babel}:
+%\begin{verbatim}
+%\documentclass[a4paper]{article}
+%
+%\usepackage[british,american]{babel}
+%
+%\usepackage{animals3}
+%
+%\begin{document}
+%
+%\selectlanguage{british}
+%

+%\ladybirdname.
+%
+%\selectlanguage{american}
+%
+%\catname.
+%\dogname.
+%\ladybirdname.
+%
+%\end{document}
+%\end{verbatim}
+%
+%Unfortunately when used with \sty{polyglossia}, \styfmt{tracklang} can't
+%detect the requested dialect. Consider the following example
+%document:
+%\begin{verbatim}
+%\documentclass[a4paper]{article}
+%
+%\usepackage{polyglossia}
+%\setmainlanguage[variant=british]{english}
+%
+%\usepackage{animals3}
+%
+%\begin{document}
+%
+%\catname.
+%\dogname.
+%\ladybirdname.
+%
+%\end{document}
+%\end{verbatim}
+%This loads \texttt{animals3-english.ldf} but doesn't load
+%\texttt{animals3-en-GB.ldf}. The dialect has to be added to the
+%document class options:
+%\begin{verbatim}
+%\documentclass[british,a4paper]{article}
+%
+%\usepackage{polyglossia}
+%\setmainlanguage[variant=british]{english}
+%
+%\usepackage{animals3}
+%
+%\begin{document}
+%
+%\catname.
+%\dogname.
+%\ladybirdname.
+%
+%\end{document}
+%\end{verbatim}
+%
+%Other languages can be added by simply providing additional
+%\texttt{.ldf} files. For example, \texttt{animals3-german.ldf}:
+%\begin{verbatim}
+%\ProvidesAnimalsLang{german}
+%
+%\providecommand*{\germananimals}{%
+% \renewcommand*{\catname}{Katze}%
+% \renewcommand*{\dogname}{Hund}%
+% \renewcommand*{\ladybirdname}{Marienk\"afer}%
+%}
+%
+%\germananimals
+%
+%\@ifundefined{captionsgerman}%
+%{%
+% \@ifundefined{captions\CurrentTrackedDialect}{}%
+% {%

+% \csname captions\CurrentTrackedDialect\endcsname{\germananimals}%
+% }
+%}%
+%{%
+% \g@addto@macro\captionsgerman{\germananimals}%
+%}
+%\end{verbatim}
+%
+%This works fine with \sty{babel}:
+%\begin{verbatim}
+%\documentclass[a4paper]{article}
+%
+%\usepackage[ngerman]{babel}
+%
+%\usepackage{animals3}
+%
+%\begin{document}
+%
+%\catname.
+%\dogname.

+%
+%\end{document}
+%\end{verbatim}
+%It also works with \sty{ngerman}:
+%\begin{verbatim}

+%
+%\usepackage{ngerman}
+%
+%\usepackage{animals3}
+%
+%\begin{document}
+%
+%\catname.

+%

+%and with \sty{translator}:

+%\usepackage{animals3}
+%
+%\begin{document}
+%
+%\catname.
+%\dogname.
+%\ladybirdname.
+%
+%\end{document}
+%\end{verbatim}
+%
+%Since no regional variants have been provided to accompany
+%\texttt{animals3-german.ldf} this also works fine with
+%\sty{polyglossia}:
+%\begin{verbatim}
+%\documentclass[a4paper]{article}
+%
+%\usepackage{polyglossia}
+%\setmainlanguage{german}
+%
+%\usepackage{animals3}

+%
+%\subsubsection{regions.sty}
+%\label{sec:regions}
+%
+%Earlier, I~mentioned the search order for
+%\ics{IfTrackedLanguageFileExists} where if, for example, the dialect
+%is \texttt{british}, the file search will be:
+%\texttt{mypackage-british.ldf}, \texttt{mypackage-en-GB.ldf},
+%\texttt{mypackage-eng-GB.ldf}, \texttt{mypackage-en.ldf},
+%\texttt{mypackage-eng.ldf}, \texttt{mypackage-GB.ldf},
+%\texttt{mypackage-english.ldf}. You may have wondered why
+%\texttt{mypackage-GB.ldf} is included in the search. Since some
+%countries have multiple official languages, the country code on its
+%own may not indicate the language.
+%
+%The reason for including just the country code as the \meta{tag} in the
+%file search is to allow for region rather than language dependent
+%settings. For example, suppose I~want to write a package that needs
+%to know whether to use imperial or metric measurements in the
+%document, but I also want to provide multilingual support. The
+%language alone won't tell me whether to use imperial or metric (for
+%example, the US uses imperial and the UK uses metric). I could
+%provide \texttt{.ldf} files for every language and region
+%combination, but this would result in a lot redundancy.
+%
+%The example package (\texttt{regions.sty}) below illustrates this.

+%
+%\begin{document}
+%
+%\unitname: \weightunit, \lengthunit, \currencyunit.
+%
+%\end{document}
+%\end{verbatim}
+%
+%This works because \cs{IfTrackedLanguageFileExists} searches for the
+%country code before the root language label. In this case,
+%\texttt{regions-CA.ldf} is matched rather than
+%\texttt{regions-french.ldf}, so \texttt{regions-CA.ldf} is loaded by
+%\begin{verbatim}
+% \input{regions-\CurrentTrackedTag.ldf}%
+%\end{verbatim}
+%After this, the language file \texttt{regions-french.ldf} is then loaded:

+% {}%
+% {%
+% \PackageWarning{regions}{No support for language
+% `\CurrentTrackedLanguage'}%
+% }%
+%\end{verbatim}
+%
+%This assumes that there's a country code \texttt{.ldf} file
+%available. This example needs a little modification to use default
+%units in case the region is missing:

+%
+%\section{Adding Support for Language Tracking}
+%\label{sec:langsty}
+%
+%If you are writing a package that \emph{defines} languages (rather
+%than a package that provides multilingual support if the user has
+%already loaded a language package) then you can load \styfmt{tracklang}
+%and use the commands below to help other packages track your
+%defined languages.
+%
+%You can notify \styfmt{tracklang} that a user has requested a
+%particular dialect using:
+%\begin{definition}
+%\ics{AddTrackedDialect}\marg{dialect}\marg{root language label}
+%\end{definition}
+%where \meta{dialect} is the dialect label and \meta{root language
+%label} is the label for the dialect's root language. This command
+%may also be used for synonyms. If the dialect is already in the
+%tracked dialect list, it won't be added again. If the root language
+%is already in the tracked language list, it won't be added again.
+%
+%\begin{definition}
+%\ics{AddTrackedLanguage}\marg{root language label}
+%\end{definition}
+%This is equivalent to \ics{AddTrackedDialect}\marg{root language
+%label}\marg{root language label} and is provided for the cases
+%where the language doesn't have any variants or the user
+%wants the default variant for that language.
+%
+%The ISO codes are specified using:
+%\begin{definition}
+%\ics{AddTrackedIsoLanguage}\marg{code type}\marg{code}\marg{label}
+%\end{definition}
+%where \meta{code type} is the ISO code type (for example, 639-1),
+%\meta{code} is the code (for example, ``en'') and \meta{label} is
+%the language or dialect label. (The root language label for
+%ISO~639-1 or ISO~639-2 and the dialect label for the country
+%code ISO~3166-1.
+%
+%For example:
+%\begin{verbatim}
+%\ProvidesPackage{alien}
+%
+%\RequirePackage{tracklang}
+%
+%\DeclareOption{martian}{%
+% \AddTrackedLanguage{martian}%
+% \AddTrackedIsoLanguage{639-1}{xx}{martian}%
+% % code to set Martian language
+%}
+%
+%\DeclareOption{uppermartian}{%
+% \AddTrackedDialect{uppermartian}{martian}%
+% \AddTrackedIsoLanguage{639-1}{xx}{martian}%
+% \AddTrackedIsoLanguage{3166-1}{XX}{uppermartian}%
+% % code to set Upper Martian dialect
+%}
+%
+%\DeclareOption{lowermartian}{%
+% \AddTrackedDialect{lowermartian}{martian}%
+% \AddTrackedIsoLanguage{639-1}{xx}{martian}%
+% \AddTrackedIsoLanguage{3166-1}{YY}{lowermartian}%
+% % code to set Lower Martian dialect
+%}
+%\end{verbatim}
+%
+%Now other package writers who want to provide support
+%for the Martian dialects can easily detect which language options
+%the user requested through your package, and it means the user
+%doesn't have to specify all their language options through the
+%document class or through each package that has multilingual
+%support.
+%
+%If you want to track one of the dialects known to
+%\styfmt{tracklang} (for example, ``british'') you can do so
+%using:
+%\begin{definition}
+%\ics{TrackPredefinedDialect}\marg{dialect label}
+%\end{definition}
+%This will add the dialect and the ISO codes.
+%
+%For non-LaTeX packages, you can input \texttt{tracklang.tex} provided
+%the category code for \texttt{@} has been set to 11:
+%\begin{verbatim}
+%\catcode `\@11\relax
+%\input tracklang
+%\end{verbatim}
+%(Remember to revert it back afterwards if necessary.)
+%
+%\section{Plain \TeX\ Example}
+%\label{sec:plain}
+%
+%Since plain \TeX\ doesn't have document class or package options,
+%the dialects and ISO codes need to be added using the commands
+%described in the previous section. For example:
+%\begin{verbatim}
+%\catcode `\@11\relax
+%\input tracklang
+%\catcode `\@12\relax
+%
+%\TrackPredefinedDialect{british}
+%\TrackPredefinedDialect{american}
+%\TrackPredefinedDialect{canadian}
+%\TrackPredefinedDialect{canadien}
+%\TrackPredefinedDialect{belgique}
+%
+%Dialect Regions:
+%
+%\ForEachTrackedDialect{\ThisDialect}{\ThisDialect:
+% \TrackedIsoCodeFromLanguage{\TwoLetterIsoCountryCode}{\ThisDialect}. }
+%
+%Language Codes:
+%
+%\ForEachTrackedLanguage{\ThisLanguage}{\ThisLanguage:
+% \TrackedIsoCodeFromLanguage{\TwoLetterIsoLanguageCode}{\ThisLanguage}. }
+%
+%\bye
+%\end{verbatim}
+%
+%This produces:
+%\begin{quotation}

+%

+% In the event that the language hasn't been supplied through the
+% package options (or through the class options, which the package
+% options should process) we need to check if any of the known
+% language packages have been loaded. This is a bit dangerous as it
+% relies on the packages not changing their internal language
+% macros. It would be easier if all the language packages could
+% provide a reliable user interface to determine which languages have been
+% loaded.
+%
+% \begin{macrocode}
+\ifx\@tracklang@languages\@empty
+% \end{macrocode}
+% First try \sty{babel}. If \sty{babel} has been loaded, the
+% languages are stored in \cs{bbl@loaded}, so check if this command
+% has been defined, and if it has add those languages.
+% \begin{macrocode}
+ \@ifundefined{bbl@loaded}%

+% If \sty{translator} has been loaded, the languages are stored in
+% \cs{trans@languages}

+% language, so check this for all known languages. I don't know how
+% to check for variants.

+% ISO language code. The 3166-1 codes are used to map the dialect
+% language to the ISO country code. The country code is
+% omitted if ambiguous (for example, the language is spoken in
+% multiple countries). Some ``dialects'' are just synonyms for a
+% language name, such as ``francais'' or ``frenchb''. Some of the
+% languages have two ISO 639-2 codes designated as ``B''
+% (bibliographic) or ``T'' (terminology). In these cases the
+% terminology code is used as the primary 639-2 code.
