%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).

%\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} or with recent versions
%of \sty{babel} or 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'', which can result in some redundancy.
%
%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'',
%but it doesn't set the country code.
%
%If any document class or package options are passed to
%\styfmt{tracklang}, then \styfmt{tracklang} won't bother checking
%for \sty{babel}, \sty{translator}, \sty{ngerman} or
%\sty{polyglossia}. So, if the above example is changed to:
%\begin{verbatim}
%\documentclass[british]{article}
%\usepackage{translator}
%\usepackage{tracklang}
%\end{verbatim}
%then the dialect list will just consist of ``british'' rather than
%``english,british''. This does, however, mean that if the user mixes
%class and package options, only the class options will be detected.
%For example:
%\begin{verbatim}
%\documentclass[british]{article}
%\usepackage[french]{babel}
%\usepackage{tracklang}
%\end{verbatim}
%In this case, only the ``british'' option will be detected. The user
%can therefore use the document class option (or \styfmt{tracklang}
%package option) to override the dialect and set the country code
%(where provided). For example:
%\begin{verbatim}
%\documentclass[es-MX]{article}
%\usepackage[spanish]{babel}
%\usepackage{tracklang}
%\end{verbatim}
%This sets the dialect to ``mexicanspanish'' and the root language to
%``spanish''.  See \texttt{tracklang.tex} (\sectionref{sec:predefined}) 
%for all predefined options.
%
%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}. The
%exceptions to this are the \styfmt{tracklang} package options that have been
%specified in the form \meta{iso lang}-\meta{iso country}. For
%example, the package option \texttt{en-GB} behaves as though the
%user requested the package option \texttt{british}.
%
%In addition to the root language label and the dialect identifier,
%many 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
%(provided that the document class has used the standard option
%declaration mechanism).  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).
%british (ISO 3166-1: ``GB''; root: english).
%canadian (ISO 3166-1: ``CA''; root: english).
%canadien (ISO 3166-1: ``CA''; root: french).
%dutch (no specific region; root: dutch).
%francais (no specific region; root: french).
%
%Language for ISO 3166-1 ``GB'': british.
%
%Language for ISO 3166-1 ``CA'': canadian,canadien.
%
%Country ISO 3166-1 code for ``canadian'': CA.
%
%\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 there 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}\meta{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
%    {.ldf}% file suffix
%    {\input{mypackage-\CurrentTrackedTag.ldf}}% file found
%    {% not found
%      \PackageWarning{mypackage}{No support for language
%       `\ThisDialect'}%
%    }%
%  }%
%}
%{% no languages detected so use defaults
%}
%\end{verbatim}
%
%If, for example, \ics{ThisDialect} is \texttt{british}, then the file search will
%be in the order:
%\begin{enumerate}
%\item \texttt{mypackage-british.ldf}
%\item \texttt{mypackage-en-GB.ldf}
%\item \texttt{mypackage-eng-GB.ldf}
%\item \texttt{mypackage-en.ldf}
%\item \texttt{mypackage-eng.ldf}
%\item \texttt{mypackage-GB.ldf}
%\item \texttt{mypackage-english.ldf}
%\end{enumerate}
%
%If, for example, \ics{ThisDialect} is \texttt{francais}, then the file search will
%be in the order: 
%\begin{enumerate}
%\item \texttt{mypackage-francais.ldf}
%\item \texttt{mypackage-fr.ldf}
%\item \texttt{mypackage-fra.ldf}
%\item \texttt{mypackage-french.ldf}
%\end{enumerate}
%This is because the predefined \texttt{francais} option has no region assigned to it.
%
%Alternatively, if you're only providing support for the root
%languages:
%\begin{verbatim}
%\AnyTrackedLanguages
%{%
%  \ForEachTrackedLanguage{\ThisLanguage}%
%  {% try to load the language file for this root language
%    \IfTrackedLanguageFileExists{\ThisLanguage}%
%    {mypackage-}% file prefix
%    {.ldf}% file suffix
%    {\input{mypackage-\CurrentTrackedTag.ldf}}% file found
%    {% not found
%      \PackageWarning{mypackage}{No support for language
%       `\ThisLanguage'}%
%    }%
%  }%
%}
%{% no languages detected so use defaults
%}
%\end{verbatim}
%
%\subsection{Examples}
%\label{sec:examples}
%
%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}}

%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}

%Here's a sample document:

%\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}%

%    \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:

%{%

%}
%\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 given no regional information.

%
%Earlier, I~mentioned the search order for
%\ics{IfTrackedLanguageFileExists} where if, for example, the dialect
%is \texttt{british}, the file search will be:
%\begin{enumerate}
%\item \texttt{mypackage-british.ldf}
%\item \texttt{mypackage-en-GB.ldf}
%\item \texttt{mypackage-eng-GB.ldf}
%\item \texttt{mypackage-en.ldf}
%\item \texttt{mypackage-eng.ldf}
%\item \texttt{mypackage-GB.ldf}
%\item \texttt{mypackage-english.ldf}
%\end{enumerate}
%You may have wondered why
%\texttt{mypackage-GB.ldf} is included in the search given that some
%countries have multiple official languages, which means that 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 for most
%product attributes). I could provide \texttt{.ldf} files for every
%language and region combination, but this would result in a lot
%redundancy.

%\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.
%(See \texttt{tracklang.tex}, \sectionref{sec:predefined}, 
%for all predefined options. These are all the control sequences in the form
%\cs{@tracklang@add@}\meta{dialect label}.)
%
%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.)
%
%If you want some means of tracking each predefined option, you can
%define
%\begin{definition}
%\cs{@tracklang@declareoption}\marg{dialect label}
%\end{definition}
%before loading \texttt{tracklang.tex}. For example,
%\texttt{tracklang.sty} has the following code:
%\begin{verbatim}
%\newcommand*{\@tracklang@declareoption}[1]{%
%  \DeclareOption{#1}{\TrackPredefinedDialect{#1}}%
%}
%\input{tracklang}
%\end{verbatim}
%which ensures that each predefined dialect is also declared
%as a package option.
%
%\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:

%\subsubsection{Predefined Dialects}\label{sec:predefined}
%
% The ISO 639-1 and 639-2 codes are used to map the root language name to the
% ISO language code. The 3166-1 codes are used to map the
% dialect\slash variant 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.
