+Generic TeX Bundle : tex-locale v1.0 
+
+Last Modified      : 2018-08-26
+
+Author             : Nicola Talbot
+
+LaTeX usage: \usepackage{tex-locale}
+
+TeX usage: \input tex-locale
+
+LaTeX code is in tex-locale.sty. Generic TeX code is in tex-locale.tex.
+
+Requirements: tracklang and texosquery. Note that texosquery
+requires the Java Runtime Environment. See the texosquery
+documentation for setup instructions. If you can't enable piped
+shell escape, see the tex-locale documentation for an alternative
+method.
+
+This package uses both tracklang and texosquery to look up the
+locale information from the operating system and provide commands
+that can access locale-dependent information, such as the currency
+symbol and decimal separator.
+
+The LaTeX package tex-locale.sty can additionally load babel or
+polyglossia with the locale's language setting, as well as various other
+packages such as fontspec (XeLaTeX/LuaLaTeX) or fontenc + inputenc.
+
+This material is subject to the LaTeX Project Public License. 
+See http://www.ctan.org/license/lppl1.3 for the details of that license.

+%
+%\begin{abstract}
+%The generic \TeX\ \file{tex-locale.tex} code uses both \sty{tracklang}
+%(at least v1.3.4) and \sty{texosquery} (at least v1.2, but newest
+%version recommended) to look up the locale information from the
+%operating system and provide commands that can access
+%locale-dependent information, such as the currency symbol and
+%numeric separators. This works best with the shell escape when
+%building the document. (Some \hyperref[sec:noshell]{adjustments} are
+%needed to work without the shell escape.) \TeX\ Live 2017 now
+%includes \app{texosquery-jre8} on the restricted list, but the
+%\sty{texosquery} installation needs to be set up to enable this.
+%Set up instructions are in the file \file{texosquery.cfg}, which is
+%distributed with the \sty{texosquery} package.  If the application
+%isn't on the restricted list, then you'll need to enable the
+%unrestricted mode, but take care as this mode is insecure.
+%
+%Example plain \XeTeX\ document:
+%\begin{verbatim}
+%\font\nimbus="NimbusRoman-Regular" at 10pt
+%\nimbus
+%
+%\input locale
+%
+%Currency: \CurrentLocaleCurrency.
+%Date: \CurrentLocaleDate.
+%Time: \CurrentLocaleTime.
+%\bye
+%\end{verbatim}
+%
+%The \LaTeX\ package \file{tex-locale.sty} can additionally load 
+%\sty{babel} or \sty{polyglossia} with the locale's language 
+%setting, as well as various other 
+%packages such as \sty{fontspec} (\XeLaTeX\ or \LuaLaTeX) or 
+%\sty{fontenc} and \sty{inputenc}. Packages that provide currency
+%symbols can also be loaded automatically (\sty{textcomp} by default).
+%Example \LaTeX\ document:
+%\begin{verbatim}
+%\documentclass{article}
+%
+%\usepackage{tex-locale}
+%
+%\begin{document}
+%Currency: \CurrentLocaleCurrency.
+%Date: \CurrentLocaleDate.
+%Time: \CurrentLocaleTime.
+%\end{document}
+%\end{verbatim}
+%\end{abstract}
+%
+%\begin{important}
+%\TeX's restricted mode prohibits the use of quotes in the shell
+%escape for security reasons. This means that if you want the file
+%modification date and you have spaces in your filename you must use
+%the unrestricted mode to allow the filename to be delimited by
+%quotes. In general it's best to avoid spaces in file names.
+%\end{important}

+%\tableofcontents
+%\chapter{Introduction}
+%
+%The \sty{tex-locale} package is designed to set up the document's
+%locale-sensitive information by querying the relevant information
+%from the operating system using \app{texosquery}.
+%\sectionref{sec:generic} describes generic commands that can be used
+%in \LaTeX\ or plain \TeX\ documents. \sectionref{sec:latex}
+%describes the \LaTeX-specific package \file{tex-locale.sty}, which does
+%more than simply input \file{tex-locale.tex}.
+%
+%The generic code \file{tex-locale.tex} requires: \file{tracklang.tex} and
+%\file{texosquery.tex}. The \LaTeX\ package \file{tex-locale.sty}
+%additionally requires: \file{tracklang.sty}, \file{texosquery.sty},
+%\sty{etoolbox}, \sty{xfor}, \sty{ifxetex}, \sty{ifluatex}, \sty{xkeyval}
+%and optionally: 
+%\begin{itemize}
+%\item \sty{datetime2} (and associated language modules);
+%\item \sty{textcomp} or \sty{fontawesome};
+%\item \sty{fontspec} or \sty{fontenc}\&\sty{inputenc};
+%\item \sty{polyglossia} or \sty{babel};
+%\item \sty{CJK}, \sty{CJKutf8} or \sty{xeCJK};
+%\item \sty{tracklang-scripts} (provided with \sty{tracklang}).
+%\end{itemize}
+%
+%The \sty{texosquery} package (distributed separately) comes with generic 
+%\TeX\ code \file{texosquery.tex}, a simple \LaTeX\ package wrapper
+%\file{texosquery.sty} and a Java application that comes in three
+%variants:
+%\begin{itemize}
+%\item \file{texosquery-jre8.jar}: the full application, requires at
+%least Java 8.
+%\item \file{texosquery.jar}: a slightly cut-down version of the 
+%application with less locale support, requires at least Java 7.
+%\item \file{texosquery-jre5.jar}: a significantly reduced version of
+%the application with poor locale support, requires at least Java 5.
+%\emph{Less secure than the other variants.}
+%\end{itemize}
+%The Java~8 variant (\app{texosquery-jre8}) is on \TeX~Live
+%2017's restricted list, so it's possible to use it with  
+%the restricted shell escape.  The other variants should not be added
+%to the restricted list as old versions of Java are deprecated and
+%considered security risks. In particular, the Java~5 variant's file
+%listing actions are less secure as they allow file listings outside
+%of the current directory path, which the Java~7 and 8 variants
+%prohibit. If you have Java~8 installed, I recommend that you make
+%\app{texosquery-jre8} the default. This can be done by editing the
+%configuration file \file{texosquery.cfg}. See the \sty{texosquery}
+%documentation for further details. (This document assumes
+%\app{texosquery-jre8} in the examples. Substitute the appropriate command if you
+%have a different set up.)
+%
+%\begin{important}
+%MiKTeX users will need to enable piped shell escape with
+%\longarg{enable-pipes} (unless the non-shell escape method described
+%in \sectionref{sec:noshell} is used).
+%\end{important}
+%
+%The information returned by \app{texosquery} has special markup
+%that's converted by \cs{TeXOSQuery} or \cs{TeXOSQueryFromFile}. For
+%example, \ics{fhyn} is used to represent a literal hyphen (category
+%code~12) whereas \ics{thyn} is used for a textual hyphen.
+%For example, if a file name containing a hyphen is returned, the
+%hyphen will be marked as \cs{fhyn}, whereas a date containing a
+%hyphen will use \cs{thyn}.
+%
+%\section{Using the package without the shell escape}
+%\label{sec:noshell}
+%
+%The \sty{tex-locale} package is designed for use with the piped shell escape
+%(preferably the restricted mode for greater security), but it's
+%still possible to use \file{tex-locale.tex} when the shell escape is disabled,
+%although it's less convenient. (You will need at least
+%\sty{texosquery} v1.4 for this method.) 
+%
+%First compile your document with the shell escape disabled. The dry
+%run mode will automatically be on, and the \sty{texosquery} command
+%\cs{TeXOSQuery} will simply write the command it would've tried to
+%the transcript. This will be prefixed by \texttt{TeXOSQuery:}
+%
+%For example, suppose the file \texttt{test.tex} contains:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{de-CH-1996,fr-BE}
+%
+%\input locale
+%
+%Currency: \CurrentLocaleCurrency.
+%
+%\bye
+%\end{verbatim} 
+%Here the main locale has been explicitly set to
+%\texttt{en-GB} and the other locales have been set to
+%\texttt{de-CH-1996} and \texttt{fr-BE}, so the transcript file
+%\texttt{test.log} will include:
+%\begin{verbatim}
+%TeXOSQuery: texosquery-jre8 -o -r -a -n -N -C -d 'test.tex' -D en-GB
+%-D de-CH-1996 -D fr-BE
+%\end{verbatim}
+%Copy and paste this command into a command prompt or terminal and redirect the
+%output to a file. (Don't include the initial \texttt{TeXOSQuery:}
+%and don't include any line breaks.) For example (omit line break):
+%\begin{verbatim}
+%texosquery-jre8 -o -r -a -n -N -C -d 'test.tex' -D en-GB
+%-D de-CH-1996 -D fr-BE > localesettings.tex
+%\end{verbatim}
+%Then define
+%\begin{definition}[\DescribeMacro\LocaleQueryFile]
+%\cs{LocaleQueryFile}
+%\end{definition}
+%to the file name before loading \sty{tex-locale}:
+%\begin{verbatim}
+%\def\LocaleQueryFile{localesettings}
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{de-CH-1996,fr-BE}
+%
+%\input locale
+%
+%Currency: \CurrentLocaleCurrency.
+%
+%\bye
+%\end{verbatim} 
+%If you change any of the document settings you'll need to re-run
+%\app{texosquery} to update the query result file.
+%
+%\begin{important}
+%If you want the current date or time, the result files will need to
+%be updated before every document build.
+%\end{important}
+%
+%For example, if the file \texttt{test.tex} is simply:
+%\begin{verbatim}
+%\input locale
+%
+%Today: \CurrentLocaleShortDate.
+%Currency: \CurrentLocaleCurrency.
+%
+%\bye
+%\end{verbatim}
+%Then the document build process would be:
+%\begin{verbatim}
+%texosquery-jre8 -o -r -a -n -N -C -d 'test.tex' -D > testsettings.tex
+%etex '\def\LocaleQueryFile{testsettings}\input test'
+%\end{verbatim}
+%(Replace \app{etex} with \app{pdftex} or \app{xetex}, as required.)
+%
+%\begin{important}
+%If \cs{LocaleQueryFile} is defined and non-empty, the non-shell escape method 
+%will automatically be implemented even if the shell escape is actually
+%enabled.
+%\end{important}
+%
+%If you're using \LaTeX\ (\file{tex-locale.sty}), there may be an initial query with
+%\texttt{-b} or \texttt{-C} (or both) before \file{tex-locale.tex} is
+%input. The result of this will also need to be captured in a file.
+%For example:
+%\begin{verbatim}
+%texosquery-jre8 -b -C > localestysettings.tex
+%\end{verbatim}
+%This file name should be provided in the command
+%\begin{definition}[\DescribeMacro\LocaleStyQueryFile]
+%\cs{LocaleStyQueryFile}
+%\end{definition}
+%In this case you only need to update the file if you change the
+%document locales, encoding or engine. (For example, if you change the
+%value of the package options \pkgopt{main}, \pkgopt{other},
+%\pkgopt{support}, \pkgopt{inputenc} or \pkgopt{fontenc}.)
+%
+%\LaTeX\ example:
+%\begin{verbatim}
+%\documentclass{article}
+%\newcommand{\LocaleStyQueryFile}{localestysettings}
+%\newcommand{\LocaleQueryFile}{localesettings}
+%\usepackage[main=en-GB,other={de-CH-1996,fr-BE}]{tex-locale}
+%\begin{document}
+%Currency: \CurrentLocaleCurrency.
+%\end{document}
+%\end{verbatim} 
+%
+%\begin{important}
+%Even if the shell escape is on, if \cs{LocaleQueryFile} or
+%\cs{LocaleStyQueryFile} have been set (to a non-empty value), 
+%they'll be used instead.
+%\end{important}
+%
+%It's possible to define one but not the other command. For example:
+%\begin{verbatim}
+%\documentclass{article}
+%\newcommand{\LocaleStyQueryFile}{localestysettings}
+%\usepackage[main=en-GB,other={de-CH-1996,fr-BE}]{tex-locale}
+%\begin{document}
+%Currency: \CurrentLocaleCurrency.
+%\end{document}
+%\end{verbatim} 
+%This requires the shell escape for the main locale information
+%(used in \file{tex-locale.tex}) but omits the \LaTeX-specific shell
+%escape used in \file{tex-locale.sty}.
+%
+%\section{Encoding}
+%\label{sec:encoding}
+%
+%The default encoding used by \app{texosquery} when writing the
+%results to STDOUT (which are piped in through the shell escape) 
+%can be obtained with \longarg{codeset} (from v1.6). For example:
+%\begin{verbatim}
+%texosquery-jre8 --codeset
+%\end{verbatim}
+%The short form of this switch is \shortarg{cs}. So the above is
+%equivalent to
+%\begin{verbatim}
+%texosquery-jre8 -cs
+%\end{verbatim}
+%For example, if the encoding is UTF-8, then this returns
+%\begin{verbatim}
+%UTF\fhyn 8
+%\end{verbatim}
+%
+%There's a similar switch \longarg{codeset-lcs} (from v1.2) that
+%converts the encoding name to lower case and strips hyphens.
+%For example
+%\begin{verbatim}
+%texosquery-jre8 --codeset-lcs
+%\end{verbatim}
+%The short form is \shortarg{C}
+%\begin{verbatim}
+%texosquery-jre8 -C
+%\end{verbatim}
+%For example, if the encoding is UTF-8, then this returns
+%\begin{verbatim}
+%utf8
+%\end{verbatim}
+%(The switches are case-sensitive. The lower case \shortarg{c} has a
+%different meaning.)
+%
+%The document encoding must match the encoding used by
+%\app{texosquery} when the query is made (through \cs{TeXOSQuery} or
+%\cs{TeXOSQueryFromFile}). This is why the \LaTeX\ package
+%\file{tex-locale.sty} makes an initial query with \shortarg{C} so that
+%it can set up the appropriate input encoding when used with the
+%\pkgoptfmt{inputenc=auto} package option. If the document doesn't use
+%this interface, then the encoding needs to be correctly set before
+%the query is made.
+%
+%You have a choice of either changing the document encoding to match
+%the encoding used by \app{texosquery} or by changing
+%\app{texosquery}'s encoding to match all your documents.
+%For example, if your Java runtime environment is set up so that the
+%default file encoding is ISO~8859-1 (Latin-1) but you always use
+%UTF-8 in your source code, then you can instruct \app{texosquery} to
+%use UTF-8 with the \longarg{encoding} option (from v1.6). For example:
+%\begin{verbatim}
+%texosquery-jre8 --encoding UTF-8 -N
+%\end{verbatim}
+%will ensure that the currency symbol is written as a UTF-8
+%character. The short form is \shortarg{enc}. For example:
+%\begin{verbatim}
+%texosquery-jre8 -enc UTF-8 -N
+%\end{verbatim}
+%You can append this option to the definition of
+%\cs{TeXOSInvokerName}. For example:
+%\begin{verbatim}
+%\def\TeXOSInvokerName{texosquery-jre8 -enc UTF-8}
+%\end{verbatim}
+%
+%There are two hooks which, if defined, are used immediately before
+%or immediately after the main query is made in \file{tex-locale.tex}.
+%The hook used before the query is
+%\begin{definition}[\DescribeMacro\localeprequery]
+%\cs{localeprequery}
+%\end{definition}
+%and the hook used after the query is
+%\begin{definition}[\DescribeMacro\localepostquery]
+%\cs{localepostquery}
+%\end{definition}
+%These may start and end a grouping, if required, as the result from
+%the query is given a global assignment, so these may be used to
+%temporarily switch the input encoding just for the query. This is
+%done by \file{tex-locale.sty} if it detects that the document requires
+%\sty{CJKutf8}. In this case it defines the hooks to locally switch
+%the encoding while the CJK characters are read from the query result.
+%
+%In addition to using markup commands like \cs{fhyn} and \cs{thyn},
+%\app{texosquery} also wraps non-ASCII characters in the argument of
+%\cs{fwrp} (which expands to \cs{texosquerynonasciidetokwrap}) and 
+%\cs{twrp} (which expands to \cs{texosquerynonasciiwrap}). The
+%expanded versions of these commands may be changed to deal with
+%non-ASCII characters, but in general it's simpler to either use the
+%same encoding as the document or use the hooks to temporarily switch
+%encoding while the information is read.
+%
+%\chapter{Generic Use}
+%\label{sec:generic}
+%
+%The commands available for generic use are defined in
+%\file{tex-locale.tex}. Plain \TeX\ users can load this using \cs{input}:
+%\begin{verbatim}
+%\input locale
+%\end{verbatim}
+%\LaTeX\ users are also able to do this, but are better off loading
+%\file{tex-locale.sty} instead:
+%\begin{verbatim}
+%\usepackage{tex-locale}
+%\end{verbatim}
+%This does more than simply inputting \file{tex-locale.tex} as it also
+%loads other packages as well, such as \sty{babel} or
+%\sty{polyglossia}.  See \sectionref{sec:latex} for \LaTeX\ package options.
+%
+%By default \file{tex-locale.tex} assumes that the document locale should
+%match your own locale as identified by your operating system. This
+%means that the same document code will produce different results
+%when compiled in different locations. If you want information for a
+%specific locale, then you need to identify the document's main
+%locale and optionally other locales. For plain \TeX\ users, this
+%means defining \cs{LocaleMain} and \cs{LocaleOther} \emph{before} loading
+%\file{tex-locale.tex}. For \LaTeX\ users, this is done through the
+%package options provided by \file{tex-locale.sty}.
+%
+%\begin{definition}[\DescribeMacro\LocaleMain]
+%\cs{LocaleMain}
+%\end{definition}
+%If this is defined before \file{tex-locale.tex} is input, then this may
+%be defined as the keyword \texttt{locale}:
+%\begin{verbatim}
+%\def\LocaleMain{locale}
+%\end{verbatim}
+%or the relevant language tag. For example:
+%\begin{verbatim}
+%\def\LocaleMain{de-CH-1996}
+%\end{verbatim}
+%The \texttt{locale} keyword indicates that the main locale should be
+%found by querying the operating system (using \app{texosquery}).
+%After \file{tex-locale.tex} has been input, this command will be set to
+%the language tag for the main locale. If \cs{LocaleMain} is undefined before
+%\file{tex-locale.tex} is input, then \texttt{locale} is assumed.
+%
+%\begin{definition}[\DescribeMacro\LocaleOther]
+%\cs{LocaleOther}
+%\end{definition}
+%If this is defined before \file{tex-locale.tex} is input, then this
+%should be a comma-separated list of language tags for the other
+%locales. If \cs{LocaleMain} has been defined to a language tag, the
+%list may also include the keyword \texttt{locale} to indicate the
+%operating system's locale.
+%
+%Note that the generic \file{tex-locale.tex} doesn't load \sty{babel} or
+%\sty{polyglossia}, but it does track each language using
+%\sty{tracklang}'s interface. You can switch to any of these locales
+%using\label{pg:selectlocale}
+%\begin{definition}[\DescribeMacro\selectlocale]
+%\cs{selectlocale}\marg{locale}
+%\end{definition}
+%where \meta{locale} is either a language tag or \sty{tracklang}
+%dialect label. If the locale is unrecognised, an error will occur
+%unless \sty{texosquery}'s dry run mode is on, in which case it will
+%just be a warning.
+%
+%This uses \sty{tracklang}'s
+%\cs{SetCurrentTrackedDialect}\marg{dialect} but additionally, if
+%\cs{selectlanguage} has been defined, it will try to determine the
+%correct label to pass to \ics{selectlanguage}.
+%
+%This means that if you use \LaTeX\ with \file{tex-locale.sty}, which
+%loads \sty{babel} or \sty{polyglossia}, then you don't need to
+%remember, for example, that \texttt{en-GB} has the \sty{babel}
+%dialect label \texttt{british}, and can simply do
+%\begin{verbatim}
+%\selectlocale{en-GB}
+%\end{verbatim}
+%If \cs{selectlanguage} isn't defined, then this command doesn't
+%switch the document language (that is, it doesn't change the
+%hyphenation patterns or \cs{languagename}) but it does allow 
+%the \cs{CurrentLocale\ldots} commands (described in \sectionref{sec:currentlocale}) to reflect
+%the change in locale.
+% 
+%Here's a plain \XeTeX\ document that sets up three locales for the
+%document. The first (main one) is obtained from the operating system
+%(because \cs{LocaleMain} isn't defined) and the other two are
+%explicitly set by defining \cs{LocaleOther} before \file{tex-locale.tex}
+%is input:
+%\begin{verbatim}
+%\def\LocaleOther{fr-BE,de-CH-1996}
+%
+%\input locale
+%
+%Currency: \CurrentLocaleCurrency.
+%
+%\selectlocale{fr-BE}
+%
+%Currency: \CurrentLocaleCurrency.
+%
+%\selectlocale{de-CH-1996}
+%
+%Currency: \CurrentLocaleCurrency.
+%\bye
+%\end{verbatim}
+%If this document is in a file called \file{test.tex}, then it can be
+%compiled using:
+%\begin{verbatim}
+%pdftex --shell-escape test
+%\end{verbatim}
+%or
+%\begin{verbatim}
+%etex --shell-escape test
+%\end{verbatim}
+%or
+%\begin{verbatim}
+%xetex --shell-escape test
+%\end{verbatim}
+%or
+%\begin{verbatim}
+%luatex --shell-escape test
+%\end{verbatim}
+%(Omit \longarg{shell-escape} if the application given by
+%\cs{TeXOSInvokerName} is on the restricted list.)
+%
+%The equivalent \LaTeX\ document is:
+%\begin{verbatim}
+%\documentclass{article}
+%
+%\usepackage[other={fr-BE,de-CH-1996}]{tex-locale}
+%
+%\begin{document}
+%Currency: \CurrentLocaleCurrency.
+%
+%\selectlocale{fr-BE}
+%
+%Currency: \CurrentLocaleCurrency.
+%
+%\selectlocale{de-CH-1996}
+%
+%Currency: \CurrentLocaleCurrency.
+%
+%\end{document}
+%\end{verbatim}
+%If this document is in a file called \file{test.tex}, then it can be
+%compiled using:
+%\begin{verbatim}
+%pdflatex --shell-escape test
+%\end{verbatim}
+%or
+%\begin{verbatim}
+%latex --shell-escape test
+%\end{verbatim}
+%or
+%\begin{verbatim}
+%xelatex --shell-escape test
+%\end{verbatim}
+%or
+%\begin{verbatim}
+%lualatex --shell-escape test
+%\end{verbatim}
+%(Again, omit \longarg{shell-escape} if the application given by
+%\cs{TeXOSInvokerName} is on the restricted list.)
+%
+%In the first two cases (\texttt{pdflatex} or \texttt{latex}),
+%\sty{babel} will be loaded (and also \sty{fontenc} and \sty{inputenc}
+%and various other packages). Whereas in the last two cases 
+%(\texttt{xelatex} or \texttt{lualatex}),
+%\sty{polyglossia} will be loaded (and also \sty{fontspec} and
+%various other packages). This means that \cs{selectlocale} will also
+%use \cs{selectlanguage} to switch the document language. In the
+%plain \TeX\ version, \cs{languagename} remains undefined.
+%
+%The other difference between the plain \TeX\ and the \LaTeX\
+%examples, is the default output produced by
+%\cs{CurrentLocaleCurrency}. The plain \TeX\ version uses the
+%currency codes (for example, EUR) whereas the \LaTeX\ version uses
+%currency symbols. These differences are described in more detail
+%below.
+%
+%\section{General Information}
+%\label{sec:general}
+%
+%Each invocation of \app{texosquery} requires starting up the
+%Java Virtual Machine, so \file{tex-locale.tex} minimises this overhead by
+%only using a single system call. The \file{tex-locale.sty} \LaTeX\
+%package may need additional information that also requires a
+%\app{texosquery} call before \file{tex-locale.tex} is input. So \LaTeX\
+%users will have at most two system calls to \app{texosquery} when
+%loading \file{tex-locale.sty} whereas plain \TeX\ users will only have a
+%single system call when loading just \file{tex-locale.tex}.
+%
+%Since it's necessary to run \app{texosquery} to obtain all the
+%locale information, \file{tex-locale.tex} uses the opportunity to also
+%fetch more general information that may be of use.
+%
+%\begin{definition}[\DescribeMacro\LocaleOSname]
+%\cs{LocaleOSname}
+%\end{definition}
+%This expands to the operating system name. For example,
+%\texttt{Linux}.
+%
+%\begin{definition}[\DescribeMacro\LocaleOSversion]
+%\cs{LocaleOSversion}
+%\end{definition}
+%This expands to the operating system version. For example,
+%\verb|4.1.13-100.fc21.x86_64|. (Note that the underscore in this
+%case has been detokenized.)
+%
+%\begin{definition}[\DescribeMacro\LocaleOSarch]
+%\cs{LocaleOSarch}
+%\end{definition}
+%This expands to the architecture. For example,
+%\texttt{amd64}.
+%
+%\begin{definition}[\DescribeMacro\LocaleOScodeset]
+%\cs{LocaleOScodeset}
+%\end{definition}
+%This expands to the operating system's default file encoding (or the
+%value of the Java setting \texttt{file.encoding}). This uses
+%\app{texosquery}'s \shortarg{C} switch, which converts the encoding
+%name to lower case and strips the hyphens. (For example, \texttt{UTF-8}
+%is converted to \texttt{utf8}.) If you prefer to use the
+%\shortarg{cs} (or \longarg{codeset}) switch, you can define
+%\begin{definition}[\DescribeMacro\LocaleQueryCodesetParam]
+%\cs{LocaleQueryCodesetParam}
+%\end{definition}
+%to the required switch. For example:
+%\begin{verbatim}
+%\def\LocaleQueryCodesetParam{-cs}
+%\input locale
+%Encoding: \LocaleOScodeset.
+%\bye
+%\end{verbatim}
+%(Note that \cs{codeset} was added to \app{texosquery} v1.6.)
+%
+%\begin{definition}[\DescribeMacro\LocaleOStag]
+%\cs{LocaleOStag}
+%\end{definition}
+%This expands to the operating system's language tag, but note that
+%this doesn't mean that this locale has been tracked (either as the
+%main locale or one of the other document locales). It's for
+%informational purposes only.
+%
+%\begin{definition}[\DescribeMacro\LocaleNowStamp]
+%\cs{LocaleNowStamp}
+%\end{definition}
+%This expands to the current date-time in PDF format. This is like
+%the PDF primitive \ics{pdfcreationdate} (also available with \LuaTeX\
+%through \cs{pdffeedback}). Since \cs{pdfcreationdate} isn't provided
+%by \XeTeX, \cs{LocaleNowStamp} can be used instead if required.
+%
+%You can also obtain the file modification date of the document
+%source file. The file is assumed to be \cs{jobname}\texttt{.tex},
+%but you can choose another instead by first defining
+%\begin{definition}[\DescribeMacro\LocaleMainFile]
+%\cs{LocaleMainFile}
+%\end{definition}
+%before loading \file{tex-locale.tex}. The value should be the file name.
+%For example:
+%\begin{verbatim}
+%\def\LocaleMainFile{mydoc.tex}
+%\input locale
+%\end{verbatim}
+%You can define this command to empty if you don't want the file 
+%modification PDF date-stamp. For example:
+%\begin{verbatim}
+%\def\LocaleMainFile{}
+%\input locale
+%\end{verbatim}
+%If the file name contains spaces, you can't use the restricted shell
+%escape and will have to use the less secure unrestricted mode instead.
+%
+%If \cs{LocaleMainFile} is not empty, the modification date can be
+%accessed using
+%\begin{definition}[\DescribeMacro\LocaleFileMod]
+%\cs{LocaleFileMod}
+%\end{definition}
+%For example:
+%\begin{verbatim}
+%\input locale
+%
+%\pdfinfo{
+%  /CreationDate (\LocaleNowStamp)
+%  /ModDate (\LocaleFileMod)
+%}
+%
+%Now: \LocaleNowStamp.
+%Mod: \LocaleFileMod.
+%
+%\bye
+%\end{verbatim}
+%This command will be empty if the modification date wasn't found.
+%
+%\section{Attributes}
+%\label{sec:attributes}
+%
+%The \file{tex-locale.tex} package stores and references information
+%through the use of attributes. These are set using:
+%\begin{definition}[\DescribeMacro\LocaleSetAttribute]
+%\cs{LocaleSetAttribute}\marg{label}\marg{attribute}\marg{value}
+%\end{definition}
+%and accessed using
+%\begin{definition}[\DescribeMacro\LocaleGetAttribute]
+%\cs{LocaleGetAttribute}\marg{label}\marg{attribute}
+%\end{definition}
+%The \meta{label} identifies the type of information,
+%\meta{attribute} is the attribute's label and \meta{value} is the
+%attribute's value.
+%
+%There are three particular types of identifiers: locales, regions
+%and currencies. For convenience, there are some shortcut commands so
+%you don't need to use the special prefix part of the label.
+%
+%For locales, where \meta{dialect} is the \sty{tracklang} dialect
+%label associated with that locale:
+%\begin{definition}[\DescribeMacro\LocaleSetDialectAttribute]
+%\cs{LocaleSetDialectAttribute}\marg{dialect}\marg{attribute}\marg{value}
+%\end{definition}
+%\begin{definition}[\DescribeMacro\LocaleGetDialectAttribute]
+%\cs{LocaleGetDialectAttribute}\marg{dialect}\marg{attribute}
+%\end{definition}
+%
+%Region attributes are set using:
+%\begin{definition}[\DescribeMacro\LocaleSetRegionAttribute]
+%\cs{LocaleSetRegionAttribute}\marg{region code}\marg{attribute}\marg{value}
+%\end{definition}
+%where \meta{region code} is the ISO territory code (for example,
+%\texttt{GB} or \texttt{CH}).
+%You can fetch a region's attribute value using:
+%\begin{definition}[\DescribeMacro\LocaleGetRegionAttribute]
+%\cs{LocaleGetRegionAttribute}\marg{region code}\marg{attribute}
+%\end{definition}
+%
+%Currency attributes are set using:
+%\begin{definition}[\DescribeMacro\LocaleSetCurrencyAttribute]
+%\cs{LocaleSetCurrencyAttribute}\marg{currency code}\marg{attribute}\marg{value}
+%\end{definition}
+%where \meta{currency code} is the ISO currency code (for example,
+%\texttt{GBP} or \texttt{EUR}).
+%You can fetch a currency's attribute value using:
+%\begin{definition}[\DescribeMacro\LocaleGetCurrencyAttribute]
+%\cs{LocaleGetCurrencyAttribute}\marg{currency code}\marg{attribute}
+%\end{definition}
+%
+%There's a debugging command available that uses \ics{show} to show
+%an attribute's value (or an error if undefined):
+%\begin{definition}[\DescribeMacro\localeshowattribute]
+%\cs{localeshowattribute}\marg{label}\marg{attribute}
+%\end{definition}
+%
+%Again there are shortcuts for the dialect, region and currency attribute groups:
+%\begin{definition}[\DescribeMacro\localeshowdialectattribute]
+%\cs{localeshowdialectattribute}\marg{dialect}\marg{attribute}
+%\end{definition}
+%\begin{definition}[\DescribeMacro\localeshowregionattribute]
+%\cs{localeshowregionattribute}\marg{region code}\marg{attribute}
+%\end{definition}
+%\begin{definition}[\DescribeMacro\localeshowcurrencyattribute]
+%\cs{localeshowcurrencyattribute}\marg{currency code}\marg{attribute}
+%\end{definition}
+%Further details of these and other attribute commands can be found in 
+%\sectionref{sec:code.attributes}.
+%
+%For the most part, the attributes are stored and accessed internally
+%by the various commands described in this chapter, so you
+%won't usually need to worry about them. However, you can modify the
+%attributes. For example, the \texttt{de-CH-1996} locale uses an
+%apostrophe \verb|'| as the numeric group separator. This is actually
+%returned by \app{texosquery} as the 0x27 straight apostrophe from
+%the Basic Latin block. This isn't a problem for plain \TeX\ using
+%the default Computer Modern font, as illustrated by the following
+%document:
+%\begin{verbatim}
+%1'234.5
+%\bye
+%\end{verbatim}
+%This uses a curly quote in the resulting 1'234.5. However, changing the font can result in a
+%straight apostrophe instead, as illustrated in this plain \XeTeX\
+%document:
+%\begin{verbatim}
+%\font\nimbus="NimbusRoman-Regular" at 10pt
+%\nimbus
+%
+%1'234.5
+%\bye
+%\end{verbatim}
+%This isn't a problem with \XeLaTeX\ if the \sty{fontspec} package is
+%used:
+%\begin{verbatim}
+%\documentclass{article}
+%\usepackage{fontspec}
+%\setmainfont{NimbusRoman-Regular}
+%
+%\begin{document}
+%1'234.5
+%\end{document}
+%\end{verbatim}
+%
+%So a plain \XeTeX\ user might prefer to change the numeric group
+%separator to the right single quote character ' (0x2019).
+%The numeric group separator is provided by the \dattr{groupsep}
+%dialect attribute. The \sty{tracklang} dialect label corresponding
+%to the \texttt{de-CH-1996} locale is \texttt{nswissgerman}. So the 
+%group separator for this dialect can be changed by setting the
+%attribute to the new value using:
+%\begin{code}
+%\cs{LocaleSetDialectAttribute}\{nswissgerman\}\{groupsep\}\{\textquoteright\}
+%\end{code}
+%(See \sectionref{sec:generalattr} to convert a language tag to
+%dialect label.)
+%
+%\subsection{Attribute Lists}
+%\label{sec:attrlists}
+%
+%Some attribute values may be comma-separated lists. You can
+%add a unique item to a list using:
+%\begin{definition}[\DescribeMacro\LocaleAddToAttributeList]
+%\cs{LocaleAddToAttributeList}\marg{label}\marg{attribute}\marg{item}
+%\end{definition}
+%This will do nothing if the item is already in the list, otherwise
+%it will append \meta{item} to the list. No
+%expansion is performed on \meta{item}. The item may be empty.
+%
+%\begin{definition}[\DescribeMacro\LocaleXpAddToAttributeList]
+%\cs{LocaleXpAddToAttributeList}\marg{label}\marg{attribute}\marg{item}
+%\end{definition}
+%As above but the first token of \meta{item} is expanded before
+%being added to the list.
+%
+%You can test if an item is in one of those lists using:
+%\begin{definition}[\DescribeMacro\LocaleIfInAttributeList]
+%\cs{LocaleIfInAttributeList}\marg{label}\marg{attribute}\marg{item}\marg{true}\marg{false}
+%\end{definition}
+%where \meta{item} is the item. This does \meta{true} if
+%\meta{item} is found in the \meta{attribute} list for
+%\meta{label}, otherwise it does \meta{false}. If the attribute
+%hasn't been defined, \meta{false} is done.
+%
+%There's a similar command that expands the first token of
+%\meta{item} before performing the test:
+%\begin{definition}[\DescribeMacro\LocaleIfInAttributeList]
+%\cs{LocaleIfXpInAttributeList}\marg{label}\marg{attribute}\marg{item}\marg{true}\marg{false}
+%\end{definition}
+%
+%You can iterate over the list using:
+%\begin{definition}[\DescribeMacro\LocaleForEachInAttributeList]
+%\cs{LocaleForEachInAttributeList}\marg{label}\marg{attribute}\marg{cs}\marg{body}
+%\end{definition}
+%This iterates over each element of the list, setting
+%the control sequence \meta{cs} to the current item and performing
+%\meta{body}. Note that this doesn't skip empty items.
+%
+%There are shortcut commands for the dialect, region and currency
+%attributes:
+%
+%\begin{definition}[\DescribeMacro\LocaleAddToDialectAttributeList]
+%\cs{LocaleAddToDialectAttributeList}\marg{label}\marg{attribute}\marg{item}
+%\end{definition}
+%
+%\begin{definition}[\DescribeMacro\LocaleXpAddToDialectAttributeList]
+%\cs{LocaleXpAddToDialectAttributeList}\marg{label}\marg{attribute}\marg{item}
+%\end{definition}
+%

+%
+%\begin{definition}[\DescribeMacro\LocaleForEachInCurrencyAttributeList]
+%\cs{LocaleForEachInCurrencyAttributeList}\marg{label}\marg{attribute}\marg{cs}\marg{body}
+%\end{definition}
+%
+%\subsection{General Attributes}
+%\label{sec:generalattr}
+%
+%The language tag attribute type \mattr{lang tag}{tagtodialect} is set using 
+%\begin{code}
+%\cs{LocaleSetAttribute}\marg{label}\{tagtodialect\}\marg{value}
+%\end{code}
+%and can be accessed using
+%\begin{code}
+%\cs{LocaleGetAttribute}\marg{label}\{tagtodialect\}
+%\end{code}
+%The \meta{label} is a language tag (such as \texttt{de-CH-1996})
+%and the \meta{value} is the associated \sty{tracklang} dialect label
+%(for example, \texttt{nswissgerman}).
+%This attribute is used by \ics{selectlocale} to convert the language
+%tag to the corresponding dialect label.
+%
+%If the time zone information was fetched with \app{texosquery}'s
+%\texttt{-Z} switch, then the time zone IDs will be stored
+%in the time zone \attr{timezone}{id} attribute list that can be fetched with
+%\begin{verbatim}
+%\LocaleGetAttribute{timezone}{id}
+%\end{verbatim}
+%or iterated over using \cs{LocaleForEachInAttributeList}.
+%For example:
+%\begin{verbatim}
+%\def\LocaleIfDateTimePatternsSupported#1#2{#1}
+%
+%\input locale
+%
+%Time zone IDs:
+%
+%\LocaleForEachInAttributeList{timezone}{id}{\ThisId}{\ThisId\endgraf}
+%
+%\bye
+%\end{verbatim}
+%This simply lists all the known time zone identifiers. (Since
+%\cs{LocaleForEachInAttributeList} is a short command,
+%\cs{endgraf} is used to create a paragraph break in the above
+%example.)
+%
+%There are two general currency attribute lists, where the
+%\meta{label} is \texttt{currencies} and the attribute values
+%are \attr{currencies}{official} for the list of official currency codes
+%and \attr{currencies}{regional} for the regional currency codes.
+%For example:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{en-IM,en-GG,fr-BE,nl-BE,de-DE-1996}
+%
+%\input locale
+%
+%Official: \LocaleGetAttribute{currencies}{official}.
+%Regional: \LocaleGetAttribute{currencies}{regional}.
+%
+%\bye
+%\end{verbatim}
+%produces:
+%\begin{quote}
+%Official: GBP,EUR. Regional: GBP,IMP,GGP,EUR.
+%\end{quote}
+%
+%You can iterate over these lists using
+%\cs{LocaleForEachInAttributeList}. For example:
+%\begin{verbatim}
+%% arara: xetex: {shell: on}
+%\font\nimbus="NimbusRoman-Regular" at 10pt
+%\nimbus
+%
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{en-IM,en-GG,fr-BE,nl-BE,de-DE-1996}
+%
+%\input locale
+%
+%\LocaleForEachInAttributeList{currencies}{regional}{\thiscode}%
+%{\thiscode\ (\LocaleGetCurrencyAttribute{\thiscode}{sym}) }
+%
+%\bye
+%\end{verbatim}
+%which produces:
+%\begin{quote}
+%GBP (\pounds) IMP (M\pounds) GGP (\pounds) EUR (\texteuro)
+%\end{quote}
+%
+%\subsection{Dialect Attributes}
+%\label{sec:dialectattr}
+%
+%The following attributes are associated with dialects and can be set
+%using
+%\begin{code}
+%\cs{LocaleSetDialectAttribute}\marg{dialect}\marg{attribute}\marg{value}
+%\end{code}
+%or fetched with
+%\begin{code}
+%\cs{LocaleGetDialectAttribute}\marg{dialect}\marg{attribute}
+%\end{code}
+%where \meta{dialect} is the \sty{tracklang} dialect label.
+%Known values of \meta{attribute} are listed below.
+%

+%as \cs{texosquerycurrencypound}) for regional currency
+%\meta{code}.
+%\end{itemize}
+%
+%\section{Patterns}
+%\label{sec:patterns}
+%
+%The \sty{texosquery} package provides for two types of patterns:
+%date-time and numeric. The date-time patterns may just display a
+%date, or just a time or both. They may or may not include a time
+%zone. The numeric patterns can be used to format integers, decimals,
+%scientific notation, percentages or currency. New patterns can be
+%defined by commands provided in \file{texosquery.tex}. The 
+%\sty{tex-locale} package can also fetch the patterns for the document
+%locales so that they can be applied to data in the document
+%to match the current locale.
+%
+%The numeric patterns are fairly easy to use but are tricky to
+%define. The date-time patterns are fairly easy to define but are
+%tricky to use.
+%
+%\subsection{Numeric Patterns}
+%\label{sec:numpatterns}
+%
+%The \sty{texosquery} numeric pattern symbol commands are redefined
+%by \sty{tex-locale} to use the appropriate symbol from the current
+%locale. For example, \ics{texosquerypatfmtgroupsep} is redefined to
+%use \cs{CurrentLocaleNumericGroupSep}. (See the \sty{texosquery}
+%documentation for further details of these pattern commands.)
+%
+%You can access a numeric pattern for a particular locale by querying
+%one of the dialect attributes listed in \sectionref{sec:attrnum}: \dattr{intfmt} (integer pattern), 
+%\dattr{decfmt} (decimal pattern), \dattr{curfmt} (currency pattern) or 
+%\dattr{perfmt} (percent pattern).
+%
+%These can be accessed explicitly using
+%\begin{definition}
+%\ics{LocaleGetDialectAttribute}\marg{dialect}\marg{attribute}
+%\end{definition}
+%For example:
+%\begin{verbatim}
+%\LocaleGetDialectAttribute{british}{intfmt}
+%\end{verbatim}
+%However it's simpler to use the shortcut commands described in 
+%\sectionref{sec:currpat}. For example:
+%\begin{verbatim}
+%\CurrentLocaleIntegerPattern
+%\end{verbatim}
+%
+%A pattern can be used in two ways. If it's simply used in the
+%document, then it just reproduces the pattern specification. For
+%example:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\input locale
+%
+%{\tt \CurrentLocaleDecimalPattern}
+%\bye
+%\end{verbatim}
+%This simply produces:
+%\begin{quote}
+%\texttt{\#,\#\#\#,\#\#\#,\#\#0.\#\#\#\#\#\#\#\#\#\#}
+%\end{quote}
+%This can be used for debugging purposes to check the pattern.
+%
+%The second use is to apply the pattern to a number. This is done
+%with \sty{texosquery}'s \cs{texosqueryfmtnumber} command:
+%\begin{definition}
+%\ics{texosqueryfmtnumber}\marg{pattern}\marg{int part}\marg{frac
+%part}\marg{mantissa}
+%\end{definition}
+%where \meta{pattern} is the pattern (defined using
+%\cs{texosquerydefpattern} or fetched with the \app{texosquery}
+%application), \meta{int part} is the integer part, \meta{frac part}
+%is the fractional part and \meta{mantissa} is the exponent part.
+%
+%For example:
+%\begin{verbatim}
+%% arara: xetex: {shell: on}
+%
+%\def\LocaleMain{en-GB}
+%\input locale
+%
+%\texosqueryfmtnumber{\CurrentLocaleIntegerPattern}{12}{34567}{4}
+%
+%\texosqueryfmtnumber{\CurrentLocaleCurrencyPattern}{12345}{67}{0}
+%
+%\texosqueryfmtnumber{\CurrentLocaleDecimalPattern}{123}{4567}{2}
+%
+%\texosqueryfmtnumber{\CurrentLocalePercentPattern}{123}{4567}{2}
+%\bye
+%\end{verbatim}
+%This produces:
+%\begin{quote}
+%123,456
+%
+%GBP12,345.67
+%
+%12,345.67
+%
+%1,234,567\%
+%\end{quote}
+%There are some shortcut commands provided, to allow for more
+%convenient code.
+%
+%A numeric pattern can be applied to a numeric value using
+%\begin{definition}[\DescribeMacro\localenumfmt]
+%\cs{localenumfmt}\marg{pattern}\marg{decimal}
+%\end{definition}
+%where \meta{pattern} is the pattern (as for \cs{texosqueryfmtnumber})
+%and \meta{decimal} is the numeric value in the form
+%\meta{int}\texttt{.}\meta{frac}\texttt{E}\meta{mantissa}
+%(where \texttt{.} represents the decimal separator and \texttt{E} represents 
+%the exponent separator, regardless of locale). The \texttt{.}\meta{frac} and 
+%\texttt{E}\meta{mantissa} parts are optional. 
+%
+%The \cs{localenumfmt} command splits up \meta{decimal} into the
+%\meta{int part}, \meta{frac part} and \meta{mantissa} required by
+%\cs{texosqueryfmtnumber}. It then does
+%\begin{code}
+%\meta{fmt cs}\{\cs{texosqueryfmtnumber}\marg{pattern}\marg{int part}\marg{frac part}\marg{mantissa}
+%\end{code}
+%where \meta{fmt cs} is one of:
+%\begin{definition}[\DescribeMacro\localenumfmtneg]
+%\cs{localenumfmtneg}\marg{text}
+%\end{definition}
+%if the \meta{int part} is negative, 
+%\begin{definition}[\DescribeMacro\localenumfmtzero]
+%\cs{localenumfmtzero}\marg{text}
+%\end{definition}
+%if the \meta{int part}, \meta{frac part} and \meta{mantissa} are all
+%zero, otherwise  
+%\begin{definition}[\DescribeMacro\localenumfmtpos]
+%\cs{localenumfmtpos}\marg{text}
+%\end{definition}
+%These three commands all simply default to just doing \meta{text}.
+%
+%\begin{definition}[\DescribeMacro\localeint]
+%\cs{localeint}\marg{value}
+%\end{definition}
+%This is equivalent to
+%\begin{definition}
+%\cs{localenumfmt}\{\cs{CurrentLocaleIntegerPattern}\}\marg{value}
+%\end{definition}
+%
+%\begin{definition}[\DescribeMacro\localedec]
+%\cs{localedec}\marg{decimal}
+%\end{definition}
+%As above but uses \cs{CurrentLocaleDecimalPattern}.
+%
+%\begin{definition}[\DescribeMacro\localecur]
+%\cs{localecur}\marg{decimal}
+%\end{definition}
+%As above but uses \cs{CurrentLocaleCurrencyPattern}.
+%
+%\begin{definition}[\DescribeMacro\localeper]
+%\cs{localeper}\marg{decimal}
+%\end{definition}
+%As above but uses \cs{CurrentLocalePercentPattern}.
+%
+%The above example can be simplified to:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\input locale
+%

+%As described in \sectionref{sec:currnumsym}, the currency unit can
+%be switched to a symbol by redefining \cs{localecurrchoice}. For
+%example:

+%
+%\selectlocale{de-CH-1996}
+%de-CH-1996: \localecur{12345.67}
+%
+%\bye

+%
+%You can define your own pattern using the commands provided by
+%\sty{texosquery}. For example:
+%\begin{verbatim}
+%\texosquerydefpattern{\sinumpattern}{%
+%  \sinumfmt
+%  {\decfmt{\#\,\#\#\#\,\#\#\#\,\#\#\0}{\0\#\#\#\#\#\#\#\#\#}}%
+%  {\-\#\#\#\#\#\#\#\#\0\0}%
+%}
+%\end{verbatim}
+%This can then be used with \cs{localenumfmt}. The \sty{texosquery}
+%documentation includes other examples, including a currency pattern
+%that shifts the sign before the currency symbol for negative
+%amounts:
+%\begin{verbatim}
+%\texosquerydefpattern{\curpattern}{%

+%{\pcur{\decfmt{\#\,\#\#\#\,\#\#\#\,\#\#\0}{\0\0\#\#\#\#\#\#\#\#}}{}}%

+%\subsection{Date-Time Patterns}
+%\label{sec:datetimepat}
+%
+%In addition to providing locale-sensitive strings for the current
+%date-time, the \app{texosquery} application can also provide the
+%locale's pattern that's used to describe how the dates and times
+%should be formatted. Additionally, it can provide time-zone mappings
+%from identifying labels to locale-sensitive names. Both these things
+%require extra overhead and so these functions aren't on by default.
+%
+%You can enable them by defining
+%\begin{definition}[\DescribeMacro\LocaleIfDateTimePatternsSupported]
+%\cs{LocaleIfDateTimePatternsSupported}\marg{true}\marg{false}
+%\end{definition}
+%\emph{before} you input \file{tex-locale.tex}. \LaTeX\ users can use the
+%more convenient \pkgopt{timedata} package option:
+%\begin{verbatim}
+%\usepackage[timedata]{tex-locale}
+%\end{verbatim}
+%Plain \TeX\ users need to define
+%\cs{LocaleIfDateTimePatternsSupported} so that it does the \meta{true}
+%argument and ignores the \meta{false} argument:
+%\begin{verbatim}
+%\def\LocaleIfDateTimePatternsSupported#1#2{#1}
+%\input locale
+%\end{verbatim}
+%
+%If enabled, \sty{tex-locale} will add the \texttt{-M} and \texttt{-Z}
+%switches to the \app{texosquery} command invocation. This will
+%additionally redefine \sty{texosquery}'s pattern format commands 
+%(such as \cs{texosqueryfmtpatMMM}) to use the appropriate commands
+%for the current locale. For example, \cs{texosqueryfmtpatMMM}\marg{n} is
+%redefined to use \cs{CurrentLocaleShortMonthName}\marg{n}. (See the
+%\sty{texosquery} documentation for further details on these
+%commands.)
+%
+%If date-time patterns are supported then the current date-time data will be 
+%stored in
+%\begin{definition}[\DescribeMacro\LocaleDateTimeInfo]
+%\cs{LocaleDateTimeInfo}
+%\end{definition}
+%This will be empty if date-time patterns aren't supported.
+%
+%The value of this command contains all the information for the current date-time provided
+%in a format that can easily be parsed by date or time patterns.
+%(This is done through \sty{texosquery}'s \ics{texosqueryfmtdatetime}
+%command, which is internally used by
+%\ics{LocaleApplyDateTimePattern}, described below.)
+%For example, \cs{LocaleDateTimeInfo} might be set to
+%\begin{verbatim}
+%{1}{2017}{2017}{3}{12}{4}{85}{26}{4}{7}{1}{19}{19}{7}{7}{16}{39}{136}
+%{{1}{0}{Europe/London}{1}}
+%\end{verbatim}
+%(Line break inserted above for clarity.) See the \sty{texosquery}
+%documentation for details of this syntax.
+%
+%Alternatively you can use \sty{texosquery}'s pattern generator to
+%create your own date-time pattern and explicitly use
+%\cs{texosqueryfmtdatetime}. In which case \cs{LocaleDateTimeInfo}
+%provides a convenient way of applying the pattern to the current
+%date-time.  For example:
+%\begin{verbatim}
+%\def\LocaleIfDateTimePatternsSupported#1#2{#1}
+%\def\LocaleMain{en-GB}
+%\input locale
+%
+%\texosquerydefpattern{\pattern}{\%3E \%1d \%3M \%4y \%2H:\%2m:\%2s \%2z}
+%
+%\ifx\LocaleDateTimeInfo\empty
+%\else
+%  \expandafter\texosqueryfmtdatetime\expandafter\pattern\LocaleDateTimeInfo
+%\fi
+%\bye
+%\end{verbatim}
+%This produces:
+%\begin{quote}
+%Sun 26 Mar 2017 21:38:06 BST
+%\end{quote}
+%(assuming that was the date and time of the document build). The
+%textual elements (\qt{Sun}, \qt{Mar} and \qt{BST}) are obtained from
+%the current locale.
+%
+%If the date-time patterns are supported, you can apply a pattern to
+%a specific date or time using 
+%\begin{definition}[\DescribeMacro\LocaleApplyDateTimePattern]
+%\cs{LocaleApplyDateTimePattern}\marg{dialect}\marg{attribute}\marg{data}
+%\end{definition}
+%This uses \sty{texosquery}'s \cs{texosqueryfmtdatetime} command to
+%format a date or time according to a date-time pattern (identified
+%by \meta{attribute}) for the locale identified by \meta{dialect}.
+%The \sty{texosquery} manual provides further details on this
+%command, but essentially the first argument of \cs{texosqueryfmtdatetime}
+%should be a control sequence containing the special pattern markup
+%and the remaining arguments are the date-time data, which are
+%supplied in the \meta{data} argument of \cs{LocaleApplyDateTimePattern}.
+%
+%The \ics{LocaleDateTimeInfo} command will either be empty or set to
+%the correct data for the current date and time. This can be used
+%in the \meta{data} argument. Since \cs{LocaleDateTimeInfo} might be
+%empty, \cs{LocaleApplyDateTimePattern} will first test for this and
+%not try applying the pattern in that case. (Remember that you can
+%also define your own custom date-time patterns, as mentioned in
+%\sectionref{sec:general}.)
+%
+%Note that the \meta{dialect} is used to fetch the pattern data, but
+%the month and day names will be obtained using the
+%\cs{CurrentLocale\ldots} commands described in
+%\sectionref{sec:currdatetime}, which may not match \meta{dialect}.
+%In general it's easiest to use the shortcut 
+%\ics{CurrentLocaleApplyDateTimePattern} (\sectionref{sec:currpat}) instead to ensure the
+%pattern matches the current locale.
+%
+%The attributes associated with date-time patterns are listed below
+%(see \sectionref{sec:attrdatetime}).
+%\begin{itemize}
+%\item \dattr{fulldatefmt}: the full date format pattern (as used in 
+%\cs{LocaleFullDate}).
+%\item \dattr{longdatefmt}: the long date format pattern (as used in 
+%\cs{LocaleLongDate}).
+%\item \dattr{meddatefmt}: the medium date format pattern (as used in 
+%\cs{LocaleMediumDate}).
+%\item \dattr{shortdatefmt}: the short date format pattern (as used in 
+%\cs{LocaleShortDate}).
+%\item \dattr{fulltimefmt}: the full time format pattern (as used in 
+%\cs{LocaleFullTime}).
+%\item \dattr{longtimefmt}: the long time format pattern (as used in 
+%\cs{LocaleLongTime}).
+%\item \dattr{medtimefmt}: the medium time format pattern (as used in 
+%\cs{LocaleMediumTime}).
+%\item \dattr{shorttimefmt}: the short time format pattern (as used in 
+%\cs{LocaleShortTime}).
+%\item \dattr{fulldatetimefmt}: the full date and time format pattern.
+%\item \dattr{longdatetimefmt}: the long date and time format pattern.
+%\item \dattr{meddatetimefmt}: the medium date and time format pattern.
+%\item \dattr{shortdatetimefmt}: the short date and time format pattern.
+%\end{itemize}
+%
+%For example:
+%\begin{verbatim}
+%\def\LocaleIfDateTimePatternsSupported#1#2{#1}
+%\def\LocaleMain{en-GB}
+%
+%\input locale
+%
+%Now:
+%\CurrentLocaleApplyDateTimePattern{fulldatetimefmt}{\LocaleDateTimeInfo}.
+%\bye
+%\end{verbatim}
+%This displays:
+%\begin{quote}
+%Now: Sunday, 26 March 2017 21:12:10 British Summer Time.
+%\end{quote}
+%However, it's simpler to just use:
+%\begin{verbatim}
+%\def\LocaleIfDateTimePatternsSupported#1#2{#1}
+%\def\LocaleMain{en-GB}
+%
+%\input locale
+%
+%\def\localedatechoice#1#2#3#4{#1}
+%\def\localetimechoice#1#2#3#4{#1}
+%
+%Now: \CurrentLocaleDateTime.
+%\bye
+%\end{verbatim}
+%or with \LaTeX:
+%\begin{verbatim}
+%\documentclass{article}
+%
+%\usepackage[timedata,date=full,time=full,main={en-GB}]{tex-locale}
+%
+%\begin{document}
+%Now: \CurrentLocaleDateTime.
+%\end{document}
+%\end{verbatim}
+%
+%The date-time patterns are therefore more useful when applied to
+%something other that the current date-time. However, it's more
+%complicated to work out the data.
+%
+%For example:
+%\begin{verbatim}
+%\def\LocaleIfDateTimePatternsSupported#1#2{#1}
+%\def\LocaleMain{en-GB}
+%
+%\input locale
+%
+%\CurrentLocaleApplyDateTimePattern{fulldatetimefmt}%

+%{{1}{0}{Europe/London}{1}}}

+%
+%\section{Locale Information}
+%\label{sec:localedata}
+%
+%Information about each locale is fetched for each tracked dialect (the
+%main locale, identified by \cs{LocaleMain}, and the other locales,
+%identified by \cs{LocaleOther}). This information can be accessed
+%using the commands described below, where \meta{dialect} is a
+%\sty{tracklang} dialect label that identifies the locale. There are convenient commands
+%(\cs{CurrentLocale\ldots}) that select the appropriate command with
+%the label provided by the currently selected dialect. (See
+%\sectionref{sec:currentlocale}.)
+%
+%Most of the commands in this package are intended to be used in an
+%expandable context, and so will expand to nothing if the dialect isn't
+%recognised.
+%
+%\begin{definition}[\DescribeMacro\LocaleMainDialect]
+%\cs{LocaleMainDialect}
+%\end{definition}
+%This expands to the main locale's dialect label. For example with:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\input locale
+%\end{verbatim}
+%the main dialect is \texttt{british}.
+%
+%\begin{definition}[\DescribeMacro\LocaleMainRegion]
+%\cs{LocaleMainRegion}
+%\end{definition}
+%This expands to the main locale's region. For example, if the main
+%locale is \texttt{en-GB}, then the main region is \texttt{GB}.
+%
+%\begin{definition}[\DescribeMacro\LocaleLanguageTag]
+%\cs{LocaleLanguageTag}\marg{dialect}
+%\end{definition}
+%Expands to the language tag for the given dialect. For example, if
+%the document locales are set using:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{pt-BR,fr-BE,de-CH-1996}
+%\input locale
+%\end{verbatim}
+%then
+%\begin{verbatim}
+%\LocaleLanguageTag{british}
+%\end{verbatim}
+%will expand to \texttt{en-GB} and
+%\begin{verbatim}
+%\LocaleLanguageTag{nswissgerman}
+%\end{verbatim}
+%will expand to \texttt{de-CH-1996}.
+%
+%\begin{definition}[\DescribeMacro\LocaleLanguageName]
+%\cs{LocaleLanguageName}\marg{dialect}
+%\end{definition}
+%The name of the language associated with \meta{dialect} provided in
+%the Java virtual machine's default language.
+%
+%\begin{definition}[\DescribeMacro\LocaleLanguageNativeName]
+%\cs{LocaleLanguageNativeName}\marg{dialect}
+%\end{definition}
+%The name of the language associated with \meta{dialect} provided in
+%that language.
+%
+%For example:
+%\begin{verbatim}
+%\font\nimbus="NimbusRoman-Regular" at 10pt
+%\nimbus
+%
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{pt-BR,fr-BE}
+%
+%\input locale
+%
+%en-GB: \LocaleLanguageName{british}.
+%pt-BR: \LocaleLanguageName{brazilian}.
+%fr-BE: \LocaleLanguageName{belgique}.
+%\bye
+%\end{verbatim}
+%For me this produces:
+%\begin{quote}
+%en-GB: English. pt-BR: Portuguese. fr-BE: French.
+%\end{quote}
+%because my operating system's default language is English. If I
+%edit the \app{texosquery-jre8} bash script so that it includes
+%\begin{verbatim}
+%-Duser.language=fr
+%\end{verbatim}
+%in the \app{java} arguments, then the same document will produce:
+%\begin{quote}
+%en-GB: anglais. pt-BR: portugais. fr-BE: fran\c{c}ais.
+%\end{quote}
+%So this isn't necessarily in the same language as the main locale (or
+%any of the other locales tracked in the document). It's in the Java
+%virtual machine's default language. Compare this document with:
+%\begin{verbatim}
+%\font\nimbus="NimbusRoman-Regular" at 10pt
+%\nimbus
+%
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{pt-BR,fr-BE}
+%
+%\input locale
+%
+%en-GB: \LocaleLanguageNativeName{british}.
+%pt-BR: \LocaleLanguageNativeName{brazilian}.
+%fr-BE: \LocaleLanguageNativeName{belgique}.
+%\bye
+%\end{verbatim}
+%This produces:
+%\begin{quote}
+%en-GB: English. pt-BR: portugu\^es. fr-BE: fran\c{c}ais.
+%\end{quote}
+%So in this case each name is displayed according to its own language.
+%
+%There are similar commands for the region and variant.
+%\begin{definition}[\DescribeMacro\LocaleRegionName]
+%\cs{LocaleRegionName}\marg{dialect}
+%\end{definition}
+%The name of the region associated with \meta{dialect} provided in
+%the Java virtual machine's default language. This will be an empty
+%string if the region wasn't supplied.
+%
+%\begin{definition}[\DescribeMacro\LocaleRegionNativeName]
+%\cs{LocaleRegionNativeName}\marg{dialect}
+%\end{definition}
+%The name of the region associated with \meta{dialect} provided in
+%that language. This will be an empty string if the region wasn't supplied.
+%
+%\begin{definition}[\DescribeMacro\LocaleVariantName]
+%\cs{LocaleVariantName}\marg{dialect}
+%\end{definition}
+%The name of the variant associated with \meta{dialect} provided in
+%the Java virtual machine's default language. This will be an empty
+%string if a variant wasn't supplied.
+%
+%\begin{definition}[\DescribeMacro\LocaleVariantNativeName]
+%\cs{LocaleVariantNativeName}\marg{dialect}
+%\end{definition}
+%The name of the variant associated with \meta{dialect} provided in
+%that language. This will be an empty string if a variant wasn't supplied.
+%This may well be the same as \cs{LocaleVariantName} as the variants
+%are often identifiers (such as \texttt{1996} in the case of
+%\texttt{de-CH-1996}) that remain the same in different languages.
+%
+%You can find out if the language name, region name or variant have
+%been set using the commands listed below. In each case,
+%\meta{dialect} is again the dialect label, \meta{true} is the code
+%to do if the condition is true and \meta{false} is the code to do if
+%the condition is false.
+%
+%\begin{definition}[\DescribeMacro\LocaleIfHasLanguageName]
+%\cs{LocaleIfHasLanguageName}\marg{dialect}\marg{true}\marg{false}
+%\end{definition}
+%This tests if the dialect has an associated language name. This will
+%typically be true.
+%
+%\begin{definition}[\DescribeMacro\LocaleIfHasRegionName]
+%\cs{LocaleIfHasRegionName}\marg{dialect}\marg{true}\marg{false}
+%\end{definition}
+%This tests if the dialect has an associated region name. Some
+%language tags don't have regions supplied. For example:
+%\begin{verbatim}
+%\def\LocaleMain{en}
+%\input locale
+%\end{verbatim}
+%In this case, there's no region associated with the main locale.
+%
+%\begin{definition}[\DescribeMacro\LocaleIfHasVariantName]
+%\cs{LocaleIfHasVariantName}\marg{dialect}\marg{true}\marg{false}
+%\end{definition}
+%This tests if the dialect has an associated variant name. For
+%example, there's no variant in \texttt{de-DE} but there is a variant
+%in \texttt{de-DE-1996}.
+%
+%\section{Dates and Times}
+%\label{sec:datetimes}
+%
+%Date and time information is fetched for each tracked dialect. 
+%The \file{tex-locale.tex} code doesn't
+%modify \ics{today} (although the \file{tex-locale.sty} \LaTeX\ package
+%can load \sty{datetime2}, which does). Instead, the dates or times
+%for a specific locale can be obtained using the commands listed
+%below. The \meta{dialect} argument indicates the \sty{tracklang}
+%dialect label. See \sectionref{sec:currentlocale} for shortcut
+%commands that select the appropriate command with the label of the
+%currently selected locale.
+%
+%Dates and times are wrapped in a formatting command:
+%\begin{definition}[\DescribeMacro\localedatetimefmt]
+%\cs{localedatetimefmt}\marg{date-time text}
+%\end{definition}
+%By default this simply does its argument. For example:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%
+%\input locale
+%
+%\def\localedatetimefmt#1{{\it #1}}
+%
+%Date: \LocaleFullDate{british}.
+%
+%\bye
+%\end{verbatim}
+%This displays the date in italic. The \LaTeX\ equivalent is:
+%\begin{verbatim}
+%\documentclass{article}
+%\usepackage[main=en-GB]{tex-locale}
+%
+%\renewcommand*{\localedatetimefmt}[1]{\textit{#1}}
+%
+%\begin{document}
+%Date: \LocaleFullDate{british}.
+%\end{document}
+%\end{verbatim}
+%
+%\subsection{Dates}
+%\label{sec:localedates}
+%
+%\begin{definition}[\DescribeMacro\LocaleFullDate]
+%\cs{LocaleFullDate}\marg{dialect}
+%\end{definition}
+%This displays the full date for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%\begin{definition}[\DescribeMacro\LocaleLongDate]
+%\cs{LocaleLongDate}\marg{dialect}
+%\end{definition}
+%This displays the long date for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%\begin{definition}[\DescribeMacro\LocaleMediumDate]
+%\cs{LocaleMediumDate}\marg{dialect}
+%\end{definition}
+%This displays the medium date for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%\begin{definition}[\DescribeMacro\LocaleShortDate]
+%\cs{LocaleShortDate}\marg{dialect}
+%\end{definition}
+%This displays the short date for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%For example:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%
+%\input locale
+%
+%Full: \LocaleFullDate{british}.
+%Long: \LocaleLongDate{british}.
+%Medium: \LocaleMediumDate{british}.
+%Short: \LocaleShortDate{british}.
+%\bye
+%\end{verbatim}
+%In the above, the main locale is explicitly set by defining \cs{LocaleMain}
+%before loading \file{tex-locale.tex}. The \sty{tracklang} package
+%identifies the \texttt{en-GB} locale with the label
+%\texttt{british}.
+%
+%Different locales have different concepts of full, long, medium and
+%short dates. In most cases the short form is numeric and the full
+%form is textual. The medium form may be numeric or it may use an
+%abbreviated month name. The locale provided used by Java may also
+%influence the result. For example, if you are using
+%\app{texosquery-jre8} with \texttt{java.locale.providers} set to
+%\texttt{CLDR,JRE} then the above document will display (assuming
+%today is 2017-03-26):
+%\begin{quote}
+%Full: Sunday, 26 March 2017. Long: 26 March 2017. Medium: 26 Mar
+%2017. Short: 26/03/2017.
+%\end{quote}
+%However, if I instead use the Java 7 version (\file{texosquery.jar})
+%which doesn't support the CLDR, then the above document will
+%display:
+%\begin{quote}
+%Full: Sunday, 26 March 2017. Long: 26 March 2017. Medium:
+%26-Mar-2017. Short: 26/03/17.
+%\end{quote}
+%The CLDR provides more extensive locale support than the JRE. In the
+%case of \texttt{en-GB}, the difference is minor (as shown above),
+%but in some cases a language may be supported in the CLDR but not in
+%the JRE. For example, if in the above document I change the main
+%locale to \texttt{cy-GB} (which maps to the \sty{tracklang dialect
+%label \texttt{GBwelsh}}):
+%\begin{verbatim}
+%\def\LocaleMain{cy-GB}
+%
+%\input locale
+%
+%Full: \LocaleFullDate{GBwelsh}.
+%Long: \LocaleLongDate{GBwelsh}.
+%Medium: \LocaleMediumDate{GBwelsh}.
+%Short: \LocaleShortDate{GBwelsh}.
+%\bye
+%\end{verbatim}
+%then the Java 7 version produces US English dates:
+%\begin{quote}
+%Full: Sunday, March 26, 2017. Long: March 26, 2017. Medium: Mar 26,
+%2017. Short: 3/26/17.
+%\end{quote}
+%This is because Welsh isn't supported by the JRE, but it is
+%supported by the CLDR, so the Java 8 version (\app{texosquery-jre8})
+%does work (provided \texttt{java.locale.providers} is set to
+%\texttt{CLDR,JRE}):
+%\begin{quote}
+%Full: Dydd Sul, 26 Mawrth 2017. Long: 26 Mawrth 2017. Medium: 26
+%Mawrth 2017. Short: 26/03/2017.
+%\end{quote}
+%
+%\subsubsection{Week Days}
+%\label{sec:weekdays}
+%
+%In order to be compatible with \sty{pgfcalendar} (and hence
+%\sty{datetime2}), the \sty{tex-locale} package uses
+%a zero-based indexing where 0 represents Monday, 1 represents
+%Tuesday, etc. If you can't remember the index for a particular day, 
+%you can use the following commands:
+%\begin{definition}[\DescribeMacro\dtmMondayIndex]
+%\cs{dtmMondayIndex}
+%\end{definition}
+%This expands to 0, the index for Monday.
+%
+%\begin{definition}[\DescribeMacro\dtmTuesdayIndex]
+%\cs{dtmTuesdayIndex}
+%\end{definition}
+%This expands to 1, the index for Tuesday.
+%
+%\begin{definition}[\DescribeMacro\dtmWednesdayIndex]
+%\cs{dtmWednesdayIndex}
+%\end{definition}
+%This expands to 2, the index for Wednesday.
+%
+%\begin{definition}[\DescribeMacro\dtmThursdayIndex]
+%\cs{dtmThursdayIndex}
+%\end{definition}
+%This expands to 3, the index for Thursday.
+%
+%\begin{definition}[\DescribeMacro\dtmFridayIndex]
+%\cs{dtmFridayIndex}
+%\end{definition}
+%This expands to 4, the index for Friday.
+%
+%\begin{definition}[\DescribeMacro\dtmSaturdayIndex]
+%\cs{dtmSaturdayIndex}
+%\end{definition}
+%This expands to 5, the index for Saturday.
+%
+%\begin{definition}[\DescribeMacro\dtmSundayIndex]
+%\cs{dtmSundayIndex}
+%\end{definition}
+%This expands to 6, the index for Sunday.
+%
+%You can get the day of week name identified by the Monday=0 based
+%index for a particular dialect using
+%\begin{definition}[\DescribeMacro\LocaleDayName]
+%\cs{LocaleDayName}\marg{dialect}\marg{index}
+%\end{definition}
+%For example:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{pt-BR}
+%
+%\input locale
+%
+%en-GB: \LocaleDayName{british}{0}.
+%pt-BR: \LocaleDayName{brazilian}{0}.
+%\bye
+%\end{verbatim}
+%This produces:
+%\begin{quote}
+%en-GB: Monday. pt-BR: Segunda-feira.
+%\end{quote}
+%
+%The abbreviated day of week name can be obtained with:
+%\begin{definition}[\DescribeMacro\LocaleShortDayName]
+%\cs{LocaleShortDayName}\marg{dialect}\marg{index}
+%\end{definition}
+%This has the same syntax as the previous command. As with the date
+%commands described in the \hyperref[sec:localedates]{previous
+%section}, the support for the given locale depends on the locale
+%provider used by \app{texosquery}.
+%
+%Some languages have a different form for day of week names when used in a
+%standalone context, such as in a column header. These can be
+%obtained using the commands below, \emph{but only with
+%\app{texosquery-jre8}}. If you are using Java 7 or earlier, these
+%commands will produce identical results to the analogous command
+%above.
+%
+%\begin{definition}[\DescribeMacro\LocaleStandaloneDayName]
+%\cs{LocaleStandaloneDayName}\marg{dialect}\marg{index}
+%\end{definition}
+%The same syntax as above, this produces the standalone day of week
+%name. The abbreviated name is produced with:
+%\begin{definition}[\DescribeMacro\LocaleStandaloneShortDayName]
+%\cs{LocaleStandaloneShortDayName}\marg{dialect}\marg{index}
+%\end{definition}
+%
+%The first day of the week varies according to region. In some
+%locales, Monday is considered the first day of the week (for
+%example, en-GB), but in other locales, Sunday is the first day
+%(for example, pt-BR). You can find out which day of the week is
+%considered the first day using:
+%\begin{definition}[\DescribeMacro\LocaleFirstDayIndex]
+%\cs{LocaleFirstDayIndex}\marg{dialect}
+%\end{definition}
+%This expands to an integer index identifying the day.
+%
+%For example, Monday (0) is the first day of the week in \texttt{en-GB},
+%but Sunday (6) is the first day of the week in \texttt{pt-BR}.
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{pt-BR}
+%
+%\input locale
+%
+%First day (en-GB): \LocaleFirstDayIndex{british}.
+%First day (pt-BR): \LocaleFirstDayIndex{brazilian}.
+%
+%\bye
+%\end{verbatim}
+%So the above produces:
+%\begin{quote}
+%First day (en-GB): 0. First day (pt-BR): 6.
+%\end{quote}
+%
+%Since it's possible that you may want to use a different indexing
+%system, there are commands provided to convert between them:
+%\begin{definition}[\DescribeMacro\LocaleDayIndexFromZeroMonToOneSun]
+%\cs{LocaleDayIndexFromZeroMonToOneSun}\marg{index}
+%\end{definition}
+%This converts a day index from the Monday=0 based system to the
+%Sunday=1 based system. For example, in Monday=0 indexing then the
+%index 3 represents Thursday. In the Sunday=1 based system, the index
+%5 represents Thursday, so
+%\begin{verbatim}
+%\LocaleDayIndexFromZeroMonToOneSun{3}
+%\end{verbatim}
+%expands to 5.
+%
+%\begin{definition}[\DescribeMacro\LocaleDayIndexFromZeroMonToOneMon]
+%\cs{LocaleDayIndexFromZeroMonToOneMon}\marg{index}
+%\end{definition}
+%This converts a day index from the Monday=0 (Sunday=6) based system to 
+%the ISO-8601 Monday=1 (Sunday=7) based system. For example
+%\begin{verbatim}
+%\LocaleDayIndexFromZeroMonToOneMon{3}
+%\end{verbatim}
+%expands to 4.
+%
+%\begin{definition}[\DescribeMacro\LocaleDayIndexFromOneSunToZeroMon]
+%\cs{LocaleDayIndexFromOneSunToZeroMon}\marg{index}
+%\end{definition}
+%This converts a day index from the Sunday=1 based system to the
+%Monday=0 based system. For example
+%\begin{verbatim}
+%\LocaleDayIndexFromOneSunToZeroMon{5}
+%\end{verbatim}
+%expands to 3. (That is, it performs the reverse of 
+%\cs{LocaleDayIndexFromZeroMonToOneSun}.)
+%
+%\begin{definition}[\DescribeMacro\LocaleDayIndexFromOneMonToZeroMon]
+%\cs{LocaleDayIndexFromOneMonToZeroMon}\marg{index}
+%\end{definition}
+%This converts a day index from the ISO-8601 Monday=1 (Sunday=7) based system
+%to the Monday=0 (Sunday=6) based system. For example
+%\begin{verbatim}
+%\LocaleDayIndexFromOneMonToZeroMon{4}
+%\end{verbatim}
+%expands to 3. (That is, it performs the reverse of 
+%\cs{LocaleDayIndexFromZeroMonToOneMon}.)
+%
+%\begin{definition}[\DescribeMacro\LocaleDayIndexFromRegion]
+%\cs{LocaleDayIndexFromRegion}\marg{dialect}\marg{index}
+%\end{definition}
+%This converts the region's day of the week (starting from 1 for the
+%region's first day) to Monday=0 based indexing. The region is identified by
+%\meta{dialect}. This first uses
+%\cs{LocaleFirstDayIndex}\marg{dialect} to find the
+%1-based first day of week index for the region and then converts it
+%to the Monday=0 based system. An invalid \meta{index} results in
+%\texttt{-1}.
+%
+%For example, the \texttt{en-GB} locale has Monday as the first day
+%of the week. So if the \meta{index} argument is 1
+%\begin{verbatim}
+%\LocaleDayIndexFromRegion{british}{1}
+%\end{verbatim}
+%that indicates Monday. This is then converted to 0 (using
+%\cs{LocaleDayIndexFromOneMonToZeroMon}). If the \meta{index}
+%argument is 7
+%\begin{verbatim}
+%\LocaleDayIndexFromRegion{british}{7}
+%\end{verbatim}
+%that indicates Sunday, so this would be converted to 6.
+%
+%The \texttt{pt-BR} locale has Sunday as the first day of the week.
+%So if the \meta{index} argument is 2
+%\begin{verbatim}
+%\LocaleDayIndexFromRegion{brazilian}{2}
+%\end{verbatim}
+%that indicates Monday. This is
+%converted to 0 (using \cs{LocaleDayIndexFromOneSunToZeroMon}). If
+%the \meta{index} argument is 1
+%\begin{verbatim}
+%\LocaleDayIndexFromRegion{brazilian}{1}
+%\end{verbatim}
+%that indicates Sunday, so this would be converted to 6.
+%
+%\begin{definition}[\DescribeMacro\LocaleDayIndexToRegion]
+%\cs{LocaleDayIndexToRegion}\marg{dialect}\marg{index}
+%\end{definition}
+%This performs the reverse operation. In this case the \meta{index}
+%argument is Monday=0 based and the result is the locale's day index
+%(starting with 1 for the first day of the week).
+%
+%\subsubsection{Month Names}
+%\label{sec:monthnames}
+%
+%The month name for a given locale can be obtained using
+%\begin{definition}[\DescribeMacro\LocaleMonthName]
+%\cs{LocaleMonthName}\marg{dialect}\marg{index}
+%\end{definition}
+%where \meta{dialect} is the \sty{tracklang} dialect label that
+%identifies the locale and \meta{index} is an integer from 1
+%(January) to 12 (December) indicating the month.
+%
+%For example:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{pt-BR}
+%
+%\input locale
+%
+%en-GB: \LocaleMonthName{british}{1}.
+%pt-BR: \LocaleMonthName{brazilian}{1}.
+%
+%\bye
+%\end{verbatim}
+%produces:
+%\begin{quote}
+%en-GB: January. pt-BR: Janeiro.
+%\end{quote}
+%
+%The abbreviated month name can be obtained using
+%\begin{definition}[\DescribeMacro\LocaleShortMonthName]
+%\cs{LocaleShortMonthName}\marg{dialect}\marg{index}
+%\end{definition}
+%which has the same syntax as the previous command.
+%
+%Some languages have a different form for month names when used in a
+%standalone context, such as in a column header. These can be
+%obtained using the commands below, \emph{but only with
+%\app{texosquery-jre8}}. If you are using Java 7 or earlier, these
+%commands will produce identical results to the analogous command
+%above.
+%
+%\begin{definition}[\DescribeMacro\LocaleStandaloneMonthName]
+%\cs{LocaleStandaloneMonthName}\marg{dialect}\marg{index}
+%\end{definition}
+%The same syntax as above, this produces the standalone month
+%name. The abbreviated name is produced with:
+%\begin{definition}[\DescribeMacro\LocaleStandaloneShortMonthName]
+%\cs{LocaleStandaloneShortMonthName}\marg{dialect}\marg{index}
+%\end{definition}
+%
+%\subsection{Times}
+%\label{sec:localetimes}
+%
+%\begin{definition}[\DescribeMacro\LocaleFullTime]
+%\cs{LocaleFullTime}\marg{dialect}
+%\end{definition}
+%This displays the full time for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%\begin{definition}[\DescribeMacro\LocaleLongTime]
+%\cs{LocaleLongTime}\marg{dialect}
+%\end{definition}
+%This displays the long time for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%\begin{definition}[\DescribeMacro\LocaleMediumTime]
+%\cs{LocaleMediumTime}\marg{dialect}
+%\end{definition}
+%This displays the medium time for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%\begin{definition}[\DescribeMacro\LocaleShortTime]
+%\cs{LocaleShortTime}\marg{dialect}
+%\end{definition}
+%This displays the short time for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%As with \hyperref[sec:localedates]{dates}, the results are
+%determined by the locale provider used by \app{texosquery}.
+%For example, the Java 8 variant (\app{texosquery-jre8}) with 
+%\texttt{java.locale.providers} set to \texttt{CLDR,JRE} may produce
+%a different result to a variant of \app{texosquery} that only uses
+%the JRE provider.
+%
+%For example:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%
+%\input locale
+%
+%Full: \LocaleLongTime{british}.
+%Long: \LocaleLongTime{british}.
+%Medium: \LocaleMediumTime{british}.
+%Short: \LocaleShortTime{british}.
+%
+%\bye
+%\end{verbatim}
+%This produces:
+%\begin{quote}
+%Full: 13:43:53 BST. Long: 13:43:53 BST. Medium: 13:43:53. Short:
+%13:43.
+%\end{quote}
+%In this particular case there's no difference between using the CLDR
+%and the JRE locale providers, but note that there's no difference in
+%the full and long forms.
+%
+%There are also commands for the combined date and time:
+%\begin{definition}[\DescribeMacro\LocaleFullDateTime]
+%\cs{LocaleFullDateTime}\marg{dialect}
+%\end{definition}
+%This displays the full date and time for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%\begin{definition}[\DescribeMacro\LocaleLongDateTime]
+%\cs{LocaleLongDateTime}\marg{dialect}
+%\end{definition}
+%This displays the long date and time for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%\begin{definition}[\DescribeMacro\LocaleMediumDateTime]
+%\cs{LocaleMediumDateTime}\marg{dialect}
+%\end{definition}
+%This displays the medium date and time for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%\begin{definition}[\DescribeMacro\LocaleShortDateTime]
+%\cs{LocaleShortDateTime}\marg{dialect}
+%\end{definition}
+%This displays the short date and time for the locale identified by \meta{dialect}
+%as provided by \app{texosquery}.
+%
+%
+%\section{Numbers}
+%\label{sec:numbers}
+%
+%Different locales use different symbols to denote the decimal mark
+%or the number group separator when displaying numbers. There are
+%other numeric-related symbols that may also vary according to
+%region, such as the currency symbol, exponent, percent or per mill
+%signs. Since most of these are outside of the Basic Latin set, the
+%examples here use \XeTeX\ with a font that supports those symbols.
+%If you don't have that font installed, you will need to adapt the
+%examples accordingly.
+%
+%As with date and times, the commands describe here need the
+%\sty{tracklang} dialect label that identifies the required locale.
+%See \sectionref{sec:currentlocale} for shortcut commands that
+%automatically select the current locale's dialect label.
+%
+%In general, most of these commands won't need to be used explicitly
+%as it's easier to use a numeric pattern instead (see
+%\sectionref{sec:numpatterns}).
+%
+%\subsection{Numeric Symbols}
+%\label{sec:numsyms}
+%
+%The number group separator for a particular locale can be obtained
+%using:
+%\begin{definition}[\DescribeMacro\LocaleNumericGroupSep]
+%\cs{LocaleNumericGroupSep}\marg{dialect}
+%\end{definition}
+%where \meta{dialect} is the \sty{tracklang} dialect label
+%representing the locale.
+%
+%You can determine whether or not the locale uses a number group
+%separator using:
+%\begin{definition}[\DescribeMacro\LocaleIfNumericUsesGroup]
+%\cs{LocaleIfNumericUsesGroup}\marg{dialect}\marg{true
+%code}\marg{false code}
+%\end{definition}
+%This does \meta{true code} if the locale identified by \meta{dialect}
+%uses a number group separator otherwise it does \meta{false code}.
+%
+%The decimal mark is obtained using:
+%\begin{definition}[\DescribeMacro\LocaleNumericDecimalSep]
+%\cs{LocaleNumericDecimalSep}\marg{dialect}
+%\end{definition}
+%
+%The monetary separator is often the same as the decimal separator,
+%but isn't always, so there's a separate command for it:
+%\begin{definition}[\DescribeMacro\LocaleNumericMonetarySep]
+%\cs{LocaleNumericMonetarySep}\marg{dialect}
+%\end{definition}
+%
+%The exponent symbol is obtained using:
+%\begin{definition}[\DescribeMacro\LocaleNumericExponent]
+%\cs{LocaleNumericExponent}\marg{dialect}
+%\end{definition}
+%
+%The percent symbol is obtained using:
+%\begin{definition}[\DescribeMacro\LocaleNumericPercent]
+%\cs{LocaleNumericPercent}\marg{dialect}
+%\end{definition}
+%This will typically use \verb|\%| (the percent symbol \%).
+%
+%The per mill symbol is obtained using:
+%\begin{definition}[\DescribeMacro\LocaleNumericPermill]
+%\cs{LocaleNumericPermill}\marg{dialect}
+%\end{definition}
+%This will typically be a character outside the Basic Latin set, so
+%the document will need to support this symbol if required.
+%
+%\subsection{Currencies}
+%\label{sec:currencies}
+%
+%The official currency code (such as \texttt{GBP} or \texttt{USD}) is
+%obtained using:
+%\begin{definition}[\DescribeMacro\LocaleCurrencyLabel]
+%\cs{LocaleCurrencyLabel}\marg{dialect}
+%\end{definition}
+%This first checks if the \dattr{currency} attribute for the given
+%dialect is \texttt{XXX} (which denotes an unknown currency,
+%typically because there's no region associated with \meta{dialect}).
+%If the currency for \meta{dialect} is known (that is, the attribute
+%value isn't \texttt{XXX}), then that currency's official code is
+%produced.  If the currency is unknown, then it will try to fallback
+%on the main dialect's currency code if the main dialect has an
+%associated region, otherwise it will fallback on the OS currency
+%code.
+%
+%Remember that with the language tag, you're not restricted to using
+%official languages for a given region. For example, if you're
+%writing in English in Belgium, it's valid to use \texttt{en-BE} as a
+%locale. For example:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{en-BE,pt-BR}
+%
+%\input locale
+%
+%en-GB: \LocaleCurrencyLabel{british}.
+%en-BE: \LocaleCurrencyLabel{enBE}.
+%pt-BR: \LocaleCurrencyLabel{brazilian}.
+%
+%\bye
+%\end{verbatim}
+%This produces:
+%\begin{quote}
+%en-GB: GBP. en-BE: EUR. pt-BR: BRL.
+%\end{quote}
+%
+%There are a few currencies that have an unofficial currency code.
+%These are typically currencies pegged to another currency with a
+%fixed exchange rate of 1.0. The
+%official ISO currency code for one
+%region may be the code for the other currency. For example, the Isle
+%of Man currency is the Manx pound, which is kept in parity with 
+%pound sterling. The currency code for \texttt{en-IM} is returned as
+%\texttt{GBP} by Java (since IMP has no official recognition in
+%ISO~4217), but \app{texosquery} recognises that this
+%region has an unofficial currency code \texttt{IMP}. This can be
+%obtained using
+%\begin{definition}[\DescribeMacro\LocaleCurrencyRegionalLabel]
+%\cs{LocaleCurrencyRegionalLabel}\marg{dialect}
+%\end{definition}
+%This command is much the same as the previous command in that it
+%will fallback on the main or OS currency code if not known.
+%The dialect attribute \dattr{regionalcurrency} is queried for the
+%required information.
+%For most regions, this command will return the same as
+%\cs{LocaleCurrencyLabel}.
+%
+%For example:
+%\begin{verbatim}
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{en-IM,pt-BR}
+%
+%\input locale
+%
+%en-GB: \LocaleCurrencyRegionalLabel{british}.
+%en-IM: \LocaleCurrencyRegionalLabel{isleofmanenglish}.
+%pt-BR: \LocaleCurrencyRegionalLabel{brazilian}.
+%
+%\bye
+%\end{verbatim}
+%This produces:
+%\begin{quote}
+%en-GB: GBP. en-IM: IMP. pt-BR: BRL.
+%\end{quote}
+%If I had used \cs{LocaleCurrencyLabel} instead, the \texttt{en-IM}
+%currency label would've been displayed as GBP.
+%
+%The currency symbol (for example, \$ or \pounds) is obtained using
+%\begin{definition}[\DescribeMacro\LocaleCurrencySymbol]
+%\cs{LocaleCurrencySymbol}\marg{dialect}
+%\end{definition}
+%Except in the case of \$ this will include symbols outside the Basic
+%Latin set. This means that if you use this command in your document,
+%you need to ensure that the document encoding has been set up before
+%\file{tex-locale.tex} is loaded. (The \LaTeX\ \file{tex-locale.sty} package
+%can automatically load \sty{fontspec} or
+%\sty{inputenc} \& \sty{fontenc}, if required.) As with the previous
+%commands, if the currency is unknown it will try to fallback on the
+%main or OS currency. If the \dattr{currencysym} dialect attribute
+%is the same as the currency code, then the \cattr{sym} currency
+%attribute will be used instead.
+%
+%Modifying the above example:
+%\begin{verbatim}
+%\font\nimbus="NimbusRoman-Regular" at 10pt
+%\nimbus
+%
+%\def\LocaleMain{en-GB}
+%\def\LocaleOther{en-IM,pt-BR}
+%
+%\input locale
+%
+%en-GB: \LocaleCurrencySymbol{british}.
+%en-IM: \LocaleCurrencySymbol{isleofmanenglish}.
+%pt-BR: \LocaleCurrencySymbol{brazilian}.
+%
+%\bye
+%\end{verbatim}
+%This produces:
+%\begin{quote}
+%en-GB: \pounds. en-IM: M\pounds. pt-BR: R\$.
+%\end{quote}
+%The \XeLaTeX\ equivalent is:
+%\begin{verbatim}
+%\documentclass{article}
+%
+%\usepackage[main={en-GB},other={en-IM,pt-BR}]{tex-locale}
+%\setmainfont{NimbusRoman-Regular}
+%
+%\begin{document}
+%en-GB: \LocaleCurrencySymbol{british}.
+%en-IM: \LocaleCurrencySymbol{isleofmanenglish}.
+%pt-BR: \LocaleCurrencySymbol{brazilian}.
+%\end{document}
+%\end{verbatim}
+%
+%Alternatively, you can use:
+%\begin{definition}[\DescribeMacro\LocaleCurrencyTeXSymbol]
+%\cs{LocaleCurrencyTeXSymbol}\marg{dialect}
+%\end{definition}
+%This works in the same way as the previous command, except
+%that it checks the \dattr{currencytex} dialect attribute.
+%If this attribute is the same as the currency code, then
+%the \cattr{tex} currency attribute is used instead.
+%
+%This command uses control sequences instead of the actual currency
+%character. Since both \sty{texosquery} and \sty{tex-locale} are designed
+%for generic \TeX\ use, \sty{texosquery} just performs some limited
+%tests for the existence of common command names (such as \cs{pounds}
+%or \cs{euro}). If it can't find an appropriate command to use, the
+%currency commands simply expand to a textual tag.
+%
+%For example, when \file{texosquery.tex} is input, it checks for the
+%existence of \cs{faGbp} and \cs{pounds}. If one of those commands
+%exist, then \ics{texosquerycurrencypound} is defined to that
+%commands, otherwise it's defined to just \qt{pound}. For the Euro
+%symbol (\ics{texosquerycurrencyeuro}) the code checks for
+%\cs{faEuro}, \cs{texteuro} and \cs{euro}. (See the \sty{texosquery}
+%package for more information about these currency commands.)
+%
+%The \LaTeX\ \file{tex-locale.sty} package will automatically load the
+%\sty{textcomp} package by default. You can switch this to another
+%package (for example, \sty{fontawesome}) using the \pkgopt{symbols}
+%package option (for example, \pkgoptfmt{symbols=fontawesome}).
+%
+%\section{Current Locale}
+%\label{sec:currentlocale}
+%
+%The commands described above mostly require a recognised \sty{tracklang}
+%dialect label in the argument to identify the locale. These labels
+%aren't intuitively obvious. There are some predefined dialect labels
+%that try to be compatible with known \sty{babel} dialects, but
+%neither \sty{babel} nor \sty{polyglossia} provide as much detail
+%about the non-language aspects of the dialect (such as the region or
+%variant). For example, there's no \sty{babel} or \sty{polyglossia}
+%setting for English in the Isle of Man (\texttt{en-IM}). Users need
+%to select the closest matching dialect (\texttt{british} in the case
+%of \texttt{en-IM}). The \sty{tracklang} package also allows an
+%unofficial language and region combination.
+%For example, a document written in English but with the regional information,
+%such as currencies, matching those for Belgium, should be identified
+%with \texttt{en-BE}. This isn't recognised as a predefined
+%\sty{tracklang} dialect, so \sty{tracklang} creates its own dialect
+%label (\texttt{enBE} in this case) when it parses this language tag.
+%
+%This makes it a bit awkward to directly use the above commands and
+%it's most likely that the required dialect will be the currently selected
+%language setting, so \file{tex-locale.tex} provides some convenient
+%wrapper commands, listed below. These \cs{CurrentLocale\ldots} commands are redefined every
+%time the locale is changed (except for \cs{CurrentLocaleDateTime}). For a document that doesn't use
+%\sty{babel} or \sty{polyglossia}, these commands can be reset using
+%\ics{selectlocale} (described on page~\pageref{pg:selectlocale}). If \file{tex-locale.tex} detects
+%any language hooks \cs{captions}\meta{language} (such as
+%\cs{captionsenglish} or \cs{captionsbritish}) then code is added to
+%those hooks to ensure that the locale is switched when the language
+%changes.
+%
+%\TeX's \ics{show} command provides a useful way of checking the
+%current settings. For example:

+%These cause three interruptions to the \TeX\ build, which look like
+%errors but are the results from each \cs{show} command. In the first
+%case the transcript shows:
+%\begin{verbatim}
+%> \CurrentLocaleMonthName=macro:
+%->\LocaleMonthName {british}.
+%\end{verbatim}
+%I haven't specifically set the locale at this point. At the end of
+%the \file{tex-locale.tex} code, the main locale was automatically
+%selected. So the current locale dialect label is \texttt{british}
+%and \cs{CurrentLocaleMonthName} has been defined as
+%\begin{verbatim}
+%\LocaleMonthName{british}
+%\end{verbatim}
+%Note that there's no check for \cs{languagename} or similar command
+%here. The dialect label is hard-coded into the definition of
+%\cs{CurrentLocaleMonthName}, so it's fully-expandable (unless the
+%month name contains any awkward non-expandable characters, which can
+%occur with \sty{inputenc} and non-ASCII characters).
+%
+%The next instance of \cs{show} produces the following lines in the
+%transcript:
+%\begin{verbatim}
+%> \CurrentLocaleMonthName=macro:
+%->\LocaleMonthName {isleofmanenglish}.
+%\end{verbatim}
+%The command \cs{CurrentLocaleMonthName} was redefined when 
+%\verb|\selectlocale{en-IM}| was used.
+%
+%Similarly for the final instance of \cs{show}:
+%\begin{verbatim}
+%> \CurrentLocaleMonthName=macro:
+%->\LocaleMonthName {brazilian}.
+%\end{verbatim}
+%
+%All the commands that are redefined with each instance of \cs{selectlocale} 
+%are listed below. Note that \cs{selectlocale} also uses
+%\sty{tracklang}'s \cs{SetCurrentTrackedDialect}, which also defines
+%a set of commands that can be used to identify information about the
+%current dialect. (See the \sty{tracklang} documentation for further

+%
+%\begin{definition}[\DescribeMacro\CurrentLocaleDate]
+%\cs{CurrentLocaleDate}
+%\end{definition}
+%This is slightly more complicated that the above. It uses
+%\begin{definition}[\DescribeMacro\localedatechoice]
+%\cs{localedatechoice}\marg{full}\marg{long}\marg{medium}\marg{short}
+%\end{definition}
+%to determine whether to use the full date \ics{LocaleFullDate}\marg{dialect},
+%the long date \ics{LocaleLongDate}\marg{dialect},
+%the medium date \ics{LocaleMediumDate}\marg{dialect} or
+%the short date \ics{LocaleShortDate}\marg{dialect}.
+%
+%This command may be defined before \file{tex-locale.tex} is loaded or
+%redefined afterwards. For example, to ensure that
+%\cs{CurrentLocaleDate} uses the medium form:
+%\begin{verbatim}
+%\def\localedatechoice#1#2#3#4{#3}
+%\input locale
+%\end{verbatim}
+%\LaTeX\ users should instead use the \pkgopt{date} package option in
+%the \file{tex-locale.sty} package interface:
+%\begin{verbatim}
+%\usepackage[date=medium]{tex-locale}
+%\end{verbatim}
+%\LaTeX\ users can also redefine the command afterwards. For example:
+%\begin{verbatim}
+%\renewcommand*{\localedatechoice}[4]{#3}
+%\end{verbatim}
+%
+%There is a similar command for the time:
+%\begin{definition}[\DescribeMacro\CurrentLocaleTime]
+%\cs{CurrentLocaleTime}
+%\end{definition}
+%This uses
+%\begin{definition}[\DescribeMacro\localetimechoice]
+%\cs{localetimechoice}\marg{full}\marg{long}\marg{medium}\marg{short}
+%\end{definition}
+%to determine whether to use the full time \ics{LocaleFullTime}\marg{dialect},
+%the long time \ics{LocaleLongTime}\marg{dialect},
+%the medium time \ics{LocaleMediumTime}\marg{dialect} or
+%the short time \ics{LocaleShortTime}\marg{dialect}. As with the date choice, this command
+%may be defined by plain \TeX\ users before \file{tex-locale.tex} is
+%input. \LaTeX\ users should use the \pkgopt{time} package option
+%instead. In both formats, the command may be redefined after
+%\sty{tex-locale} has been loaded.
+%
+%There is also a command for the combined date and time:
+%\begin{definition}[\DescribeMacro\CurrentLocaleDateTime]
+%\cs{CurrentLocaleDateTime}
+%\end{definition}
+%This doesn't use the analogous \cs{LocaleFullDateTime} etc
+%commands, but instead is simply defined as:
+%\begin{code}
+%\cs{CurrentLocaleDate}\cs{space}\cs{CurrentLocaleTime}
+%\end{code}
+%This allows for a mix of date and time styles, reflecting
+%the definitions of \cs{localedatechoice} and \cs{localetimechoice}.
+%
+%If you want a specific style (ignoring \cs{localedatechoice}
+%and \cs{localetimechoice}), you can use the following commands:
+%\begin{definition}[\DescribeMacro\CurrentLocaleFullDate]
+%\cs{CurrentLocaleFullDate}
+%\end{definition}
+%This just uses \cs{LocaleFullDate}\marg{dialect}.

+%\label{sec:latex}
+%
+%The \sty{tex-locale} package is loaded in \LaTeX\ with the usual
+%\cs{usepackage} syntax:
+%\begin{verbatim}
+%\usepackage{tex-locale}
+%\end{verbatim}
+%This does more than simply input \file{tex-locale.tex}. The options
+%are listed below.
+%
+%\begin{description}
+%\item[\pkgopt{main}=\marg{tag}] This option identifies the main locale for the
+%document. The value should be a valid language tag. If this option
+%is omitted, the main language will be obtained from the Java Runtime
+%Environment, which should match your operating system's default
+%locale. If any languages have already been tracked in your document with 
+%\sty{tracklang} prior to loading \sty{tex-locale}, the main
+%language is set to the first tracked dialect. Normally you don't
+%need to explicitly load \sty{tracklang}.
+%
+%\item[\pkgopt{other}=\marg{list}] This option identifies other
+%locales required by the document. The value should be a
+%comma-separated list of language tags or the keyword \pkgoptfmt{locale}
+%to indicate the system's default locale. The value must be grouped
+%to protect any commas from the key=value parser.
+%\begin{important}
+%This option has a cumulative effect.
+%\end{important}
+%
+%\item[\pkgopt{symbols}=\marg{name}] This option identifies the
+%symbol package to automatically load. For example,
+%\pkgoptfmt{symbols=textcomp} or \pkgoptfmt{symbols=fontawesome}. If
+%another package is required, \sty{texosquery}'s currency symbol commands
+%will need to be redefined as appropriate.
+%
+%The keyword \pkgoptfmt{none} indicates that no package is required. The
+%default is \pkgoptfmt{symbols=none} for \XeLaTeX\ or \LuaLaTeX,
+%otherwise it's \pkgoptfmt{symbols=textcomp}.
+%
+%\item[\pkgopt{support}=\marg{value}] This option identifies the
+%language support value. Available values are:
+%\begin{itemize}
+%\item \pkgoptfmt{none}: don't load any language support package;
+%\item \pkgoptfmt{auto}: load \sty{polyglossia} for \XeLaTeX\ or
+%\LuaLaTeX, otherwise load \sty{babel};
+%\item \pkgoptfmt{babel}: load \sty{babel} regardless of the \LaTeX\
+%format;
+%\item \pkgoptfmt{polyglossia}: load \sty{polyglossia} without checking
+%the \LaTeX\ format (but remember that \sty{polyglossia} doesn't work
+%with \PDFLaTeX);
+%\item \pkgoptfmt{cjk}: load CJK support with either \sty{xeCJK}
+%(\XeLaTeX/\LuaLaTeX) or \sty{CJKutf8}. This isn't fully tested, and
+%there's no support for non-UTF encoding.
+%\end{itemize}
+%
+%\item[\pkgopt{fontenc}=\marg{value}] This option indicates whether
+%or not to load the \sty{fontenc} package. The value should be one
+%of: \pkgoptfmt{none} (don't load), \pkgoptfmt{auto} (automatically load
+%with the encoding determined from the language settings), or
+%\meta{option} (indicating the package option to pass to
+%\sty{fontenc}). The default is \pkgoptfmt{fontenc=auto} unless
+%\sty{fontenc} has already been loaded.
+%
+%This option is ignored with \XeLaTeX\ or \LuaLaTeX.
+%
+%\item[\pkgopt{inputenc}=\marg{value}] This option indicates whether
+%or not to load the \sty{inputenc} package. The value should be one
+%of: \pkgoptfmt{none} (don't load), \pkgoptfmt{auto} (automatically load
+%with the encoding determined from the default obtained from
+%\sty{texosquery}), or \meta{option} (indicating the package option
+%to pass to \sty{inputenc}). The default is \pkgoptfmt{inputenc=auto}
+%but \sty{inputenc} won't be loaded if the appropriate encoding can't
+%be determined. Note that loading \sty{inputenc} before the
+%\sty{texosquery} lookup is performed will cause a problem with
+%non-ASCII characters appearing in the result.
+%
+%This option is ignored with \XeLaTeX\ or \LuaLaTeX.
+%
+%\item[\pkgopt{datetime}=\meta{value}] This option indicates whether
+%or not to load the \sty{datetime2} package. The value may be one of:
+%\begin{itemize}
+%\item \pkgoptfmt{false}: don't load \sty{datetime2};
+%\item \pkgoptfmt{iso}: load \sty{datetime2} with the package option
+%\pkgoptfmt{useregional=false} and sets the date-time style to \pkgoptfmt{iso};
+%\item \pkgoptfmt{text}: load \sty{datetime2} with the package option
+%\pkgoptfmt{useregional=text};
+%\item \pkgoptfmt{num} or \pkgoptfmt{numeric}: load \sty{datetime2} with the 
+%package option \pkgoptfmt{useregional=numeric};
+%\item \pkgoptfmt{locale}: don't load \sty{datetime2} and set \ics{today}
+%to \ics{CurrentLocaleDate}, if available.
+%\end{itemize}
+%
+%\item[\pkgopt{date}=\meta{value}] This option indicates the
+%preferred date style for \ics{CurrentLocaleDate}. The value may be
+%one of: \pkgoptfmt{full}, \pkgoptfmt{long}, \pkgoptfmt{medium}
+%\pkgoptfmt{short}. This option doesn't affect \ics{today} unless you
+%have used \pkgoptfmt{datetime=locale}.
+%
+%\item[\pkgopt{time}=\meta{value}] This option indicates the
+%preferred time style for \ics{CurrentLocaleTime}. The value may be
+%one of: \pkgoptfmt{full}, \pkgoptfmt{long}, \pkgoptfmt{medium}
+%\pkgoptfmt{short}.
+%
+%\item[\pkgopt{timedate}=\meta{boolean}] This option indicates
+%whether or not to support date and time patterns. (See
+%\sectionref{sec:datetimepat}.)
+%
+%\item[\pkgopt{currency}=\meta{value}] This option indicates the
+%preferred currency style for \ics{CurrentLocaleCurrency}. Available
+%values: \pkgoptfmt{official} (official identifier), \pkgoptfmt{unofficial}
+%unofficial identified, \pkgoptfmt{sym} (the symbol, which may include
+%non-ASCII characters) or \pkgoptfmt{tex} (use the commands provided by
+%\sty{texosquery}). The default is \pkgoptfmt{currency=sym} for
+%\XeLaTeX/\LuaLaTeX\ or \pkgoptfmt{currency=tex} otherwise.
+%
+%\end{description}
+%
+%The \sty{tex-locale} package will use \sty{texosquery} to lookup the
+%default language tag and encoding, and then attempt to load the
+%appropriate encoding and language support packages.
+%
+%For example, consider the following document:
+%\begin{verbatim}
+%\documentclass{article}
+%\usepackage{tex-locale}
+%\begin{document}
+%Currency: \CurrentLocaleCurrency.
+%\end{document}
+%\end{verbatim}
+%My default locale is \texttt{en-GB} with UTF-8 as the default file
+%encoding, so if I compile this document with \PDFLaTeX, then this is
+%essentially equivalent to:
+%\begin{verbatim}
+%\documentclass{article}
+%\usepackage[en-GB]{tracklang}
+%\usepackage[T1]{fontenc}
+%\usepackage[utf8]{inputenc}
+%\usepackage[british]{babel}
+%\usepackage[useregional]{datetime2}
+%\begin{document}
+%Currency: \pounds.
+%\end{document}
+%\end{verbatim}
+%(Other dependent packages omitted for clarity.) Whereas if I compile
+%the document with \XeLaTeX, then this is essentially equivalent to:
+%\begin{verbatim}
+%\documentclass{article}
+%\usepackage[en-GB]{tracklang}
+%\usepackage{fontspec}
+%\usepackage{polyglossia}
+%\setmainlanguage[variant=uk]{english}
+%\usepackage[useregional]{datetime2}
+%\begin{document}
+%Currency: £.
+%\end{document}
+%\end{verbatim}
+%If I still want to use \sty{babel}, then I can enforce this with:
+%\begin{verbatim}
+%\usepackage[support=babel]{tex-locale}
+%\end{verbatim}
+%Or if I don't want \sty{babel} or \sty{polyglossia}:
+%\begin{verbatim}
+%\usepackage[support=none]{tex-locale}
+%\end{verbatim}
+%
+%You can determine which language package was used with:
+%\begin{definition}[\DescribeMacro\LocaleSupportPackageCase]
+%\cs{LocaleSupportPackageCase}\marg{babel}\marg{polyglossia}\marg{neither}
+%\end{definition}
+%If either package has been loaded \ics{selectlocale}\marg{locale}
+%should automatically be implemented when the document language
+%changes, so you can the use the current locale commands described in
+%\sectionref{sec:currentlocale}.
+%
+%Example:
+%\begin{verbatim}
+%\usepackage[main={sr-Cyrl-RS},other={en-GB}]{tex-locale}
+%
+%\LocaleSupportPackageCase
