+% The main problem is that enumeration depends on the number of levels,

+% \begin{abstract}
+% I'm afraid some user commands have been changed,
+% specially |\selectlanguage| and |\uselanguage|,
+% and some other supressed---|\enablegroup| 
+% and |\disablegroup|, which have been merged into
+% |\selectlanguage|. These changes will be definitive, and I
+% had to do them in order to implement a right communication
+% to files and marks, and avoid mixing up definitions which sometimes
+% made \LaTeX\ enter in an endless loop.
+% Furthermore, the new syntax is far more robust,
+% flexible and readable.
+%
+% Most of commands for description
+% files haven't changed at all, though some of them has been 
+% reimplemented. Yet, handling of dialects has been
+% much improved; there is a new |\SetLanguage| (the old one
+% has been renamed to |\SetDialect|) and you can create
+% a dialect at any time with |\DeclareDialect| without the restrictions
+% of the now obsolete |\GenerateDialects|.
+% \end{abstract}
+%
+% 
+% \section{Introduction}
+% 
+% The package \textsf{polyglot} provides a new language selection
+% system taking advantage of the features of \LaTeXe. It provides some
+% utilities which make writing a language style quite easy and
+% straightforward.
+%
+% Some of the features implemeted by polyglot are:
+%
+% \begin{itemize}
+% \item You can switch between languages freely. You have not
+% to take care of neither head lines nor toc and bib
+% entries---the right language is always used.\footnote{Index
+%   entries follow a special syntax and
+%   the current version of \textsf{polyglot} cannot handle that. For this
+%   reason the index entries remain untouched and you may
+%   use language commands only to some extent.}
+% You can even get just a few commands from a language, not all.
+% 
+% \item ``Ligatures,'' which are shortcuts for diacritical
+% marks; for instance, in French |^e| is a synonymous
+% to |\^{e}|. Some other ligatures perform special actions,
+% as Spanish |'r| which allows divide ``extrarradio'' as 
+% ``extra-radio''. A very cool feature: in most of cases,
+% ligatures does not interfere with other definitions;
+% for instance, with the \textsf{index} package
+% |^{<entry>}| still works, provided the <entry> has
+% two or more tokens.\footnote{And provided 
+% \textsf{index} is loaded before \textsf{polyglot}.
+% \textsf{index} is a package by David Jones.}
+%
+% \item Dialects---small language variants---are supported. For
+% instance American is a variant of English with another date
+% format. Hyphenations patterns are attached to dialects and
+% different rules for US and British English can be used.
+% 
+% \item New glyphs are created if necessary. For instance, if
+% you are using |OT1| the German umlauts are lowered, but if you
+% switch to |T1| the actual font glyphs are used. Some other font
+% encoding may have their own glyphs which will be used only 
+% with that encoding.
+% 
+% \item Customization is quite easy---just redefine a command
+% of a language with |\renewcommand| when the language
+% is in force. The new definition will be remembered,
+% even if you switch back and forth between languages.
+% 
+% \item An unique layout can be used through the document,
+% even with lots of languages. If you use a class with
+% a certain layout you don't want to modify, you or the
+% class can tell \textsf{polyglot} not to touch
+% it at all.
+% \end{itemize}
+%
+% \section{Quick start}
+%
+% \subsection{Installation}
+%
+% To install the package follow these steps:
+% \begin{enumerate}
+% \item First, run |polyglot.ins|. The files |polyglot.sty|,
+%    |polyglot.ltx|, |polyglot.def| and |polyglot.cfg| are generated.
+%
+% \item Remove |polyglot.ltx| and
+%    |polyglot.def| as they are not needed in the basic installation.
+%
+% \item Move |polyglot.sty| and |polyglot.cfg| as well as the files
+%  with extensions |.ld| and |.ot1| to a place where \LaTeX{}
+%  can find them.
+% \end{enumerate}
+%
+% The files are: 
+%
+% \begin{itemize}
+% \item |polyglot.sty| is the file to be read with |\usepackage|.
+%
+% \item |polyglot.cfg| gives your system configuration.
+%
+% \item Languages are stored in files with
+%       extension |.ld|, as, for instance, |spanish.ld|, |english.ld|
+%       and so on.
+%
+% \item |polyglot.ltx| has some definitions for instalation of hyphenation
+%       patterns as well as preloading of languages and the \textsf{polyglot} style
+%       (actually |polyglot.def|).
+%
+% \item Finally, there are some files named like languages, but with extensions
+%       like font encodings.
+% \end{itemize}
+%
+% Once installed, you can use polyglot.
+% To write a, say, German document simply state the
+% |german| option in the |\documentclass| and load
+% the package with |\usepackage{polyglot}|.
+% That's all. A new layout, with new commands,
+% ligatures and, if the |OT1| encoding is in force,
+% new glyphs will be available to you, as described
+% at the end of this manual. If you are happy with
+% that you need not go further; but if you are
+% interested in advanced features (how to insert a
+% Spanish date or how to create your own ligatures,
+% for instance) just continue. 
+%
+% \section{User Interface}
+% 
+% \subsection{Groups}
+% 
+% A language has a series of commands and variables (counters and lengths)
+% stored in several groups. These groups are:
+% \begin{description}
+% \item[names] Translation of commands for titles, etc., following
+% the international \LaTeX{} conventions.
+% \item[layout] Commands and variables for the general layout of the
+% document (|enumerate|, |itemize|, etc.)
+% \item[date] Logically, commands concerning dates.
+% \item[ligatures] A way to provide ligatures, i.e., shorthands for accented
+% letters, and other special symbols.
+% \item[text] Modifications of some typografical conventions: spacing
+% before o after characters (French `:' or `;', Spanish `\%'), etc.
+% \item[tools] Supplemetary command definitions. 
+% \end{description}
+% These groups belong to two categories: names, layout, and date are
+% considered \emph{document} groups, since they are intended for
+% formatting the document; ligatures, tools and text, are considered
+% \emph{text} groups, since you will want to use them temporarily
+% for a short text in some language.
+% 
+% \subsection{Selecting a Language}
+%
+% You must load languages with |\usepackage|:
+% \begin{sample}
+% |\usepackage[english,spanish]{polyglot}|
+% \end{sample}
+% 
+% Global options (those of  |\documentclass|) will be recognized as usual.
+% The very first language will be automatically
+% selected (with the starred version, see below).
+% For this purpose, class options  are taken in consideration \emph{before} package
+% options. (Perhaps this is not the usual convention in \LaTeXe, but it is
+% more logical; in general, you will state the main language as class option
+% and the secondary ones as package options.) You can cancel this automatic
+% selection with the package option |loadonly|:
+% \begin{sample}
+% |\usepackage[german,spanish,loadonly]{polyglot}|
+% \end{sample}
+%
+% \begin{cmd}
+% |\selectlanguage*[<no-groups>]{<language>}|
+% \end{cmd}
+%
+% Selects all groups from <language>, except if there is the optional
+% argument. <no-groups> is a list of groups \emph{not} to be selected, in the
+% form |no<group>,no<group>,...|. For instance, if you dislike
+% using ligatures:
+% \begin{sample}
+% |\selectlanguage*[noligatures]{french}|
+% \end{sample}
+% This command also sets defaults to be used by the
+% unstarred version (see below).
+%
+% \begin{cmd}
+% |\selectlanguage[<groups>]{<language>}|
+% \end{cmd}
+%
+% Where <groups> is a list of <group>s and/or |no<group>|s.
+%
+% There are three posibilities:
+% \begin{itemize}
+% \item When a group is cited in the form <group>
+% (e.g., |date| or |names|), this group is selected
+% for the current language, i.e., that of the current
+% |\selectlanguage|.
+%
+% \item When a group is cited in the form |no<group>|
+% (e.g., |nodate| or |nonames|), this group is cancelled.
+%
+% \item When a group is not cited, then the default, i.e., that
+% set by the |\selectlanguage*| in force, is used; it can be
+% a |no|-form, and then the group will be disabled if
+% necessary. If there is
+% no a previous starred selection, the |no|-form will be
+% presumed in all of groups.
+% \end{itemize}
+% If no optional argument is given, then |text,ligatures,tools| are
+% presumed. Thus, at most two languages are selected at time. 
+%
+% Here is an example:
+% \begin{sample}
+% |\selectlanguage*[noligatures]{spanish}|\\
+% Now we have Spanish |names|, |date|, |layout|, |text| and |tools|,\\
+% but no |ligatures| at all.\\
+% |\selectlanguage[date,notools]{french}|\\
+% Now we have Spanish |names|, |layout| and |text|, French |date|,\\
+% but neither |ligatures| nor |tools|.\\
+% |\selectlanguage[ligatures]{german}|\\
+% Now we have Spanish |names|, |date|, |layout|, |text| and |tools|,\\
+% and German |ligatures|.\\
+% \end{sample}
+%
+% Selection is always local. There is also the possibility
+% to use |selectlanguage| as environment. 
+% \begin{sample}
+% |\begin{selectlanguage}*[<no-groups>]{<language>} <text> \end{selectlanguage}|\\
+% |\begin{selectlanguage}[<groups>]{<language>} <text> \end{selectlanguage}|
+% \end{sample}
+%
+% In general, you will use these commands without the optional
+% argument---the starred version as command at the very
+% beginning of documents and the starless version as environment
+% in a temporary change of language.
+%
+% For the sake of clarity, spaces are ignored in the optional
+% argument, so that you can write 
+% \begin{sample}
+% |\selectlanguage[date, tools, no ligatures]{spanish}|
+% \end{sample}
+%
+% \begin{cmd}
+% |\uselanguage[<groups>]{<language>}{<text>}|
+% \end{cmd}
+%
+% A command version of the |selectlanguage| environment, although only
+% the unstarred version is allowed.
+%
+% \begin{cmd}
+% |\unselectlanguage|
+% \end{cmd}
+% 
+% You can switch all of groups off
+% with |\unselectlanguage|. Thus, you return to the
+% original \LaTeX{} as far as \textsf{polyglot}
+% is concerned.\footnote{Well, not exactly. But you
+%   should not notice it at all.}
+% 
+% A typical file will look like this
+% \begin{sample}
+% |\documentclass[german]{...}|\\
+% |\usepackage[spanish]{polyglot}|\\
+% |\newenvironment{spanish}%|\\
+% |  {\begin{quote}\begin{selectlanguage}{spanish}}%|\\
+% |  {\end{selectlanguage}\end{quote}}|\\
+% |\begin{document}|\\
+% |Deutsche text|\\
+% |\begin{spanish}|\\
+% |  Texto en espa'nol|\\
+% |\end{spanish}|\\
+% |Deutsche text|\\
+% |\end{document}|\\
+% \end{sample}
+%
+% Note that |\selectlanguage*{german}| is not necessary, since
+% it is selected by the package. (Because there is no |loadonly|
+% package option.)
+% 
+% \subsection{Tools}
+%
+% \begin{cmd}
+% |\thelanguage|
+% \end{cmd}
+% 
+% The name of the current language. You \emph{cannot} redefine this command
+% in a document.
+%
+% \begin{cmd}
+% |\languagelist|
+% \end{cmd}
+%
+% A list of languages requested.
+%
+% \begin{cmd}
+% |\allowhyphens|
+% \end{cmd}
+%
+% Allows further hyphenation in words with the primitive |\accent|.
+%
+% \begin{cmd}
+% |\hexnumber  \octalnumber  \charnumber|
+% \end{cmd}
+%
+% Synonymous to |"|, |'| and |`| for numbers (|\hexnumber F3| $=$ |"F3|)
+% provided for convenience. 
+%
+% \begin{cmd}
+% |\nofiles|
+% \end{cmd}
+%
+% Not a new command really, but it has been reimplemented to optimize 
+% some internal macros related with file writing.
+%
+% \begin{cmd}
+% |\ensurelanguage|
+% \end{cmd}
+%
+% The \textsf{polyglot} package modifies internally some 
+% \LaTeX{} commands in order to do its best for making
+% sure the current language is used
+% in a head/foot line, even if the page is shipped out when another
+% language is in force.
+% Take for instance
+% \begin{sample}
+% (With |\selectlanguage*{spanish}|)\\
+% |\section{Sobre la confecci'on de t'itulos}|
+% \end{sample}
+% In this case, if the page is broken inside, say, a German text
+% |\ensurelanguage| restores |spanish| and hence the accents.
+%
+% Yet, some non-standard classes or packages can modify the marks.
+% Most of times (but not always) |\ensurelanguage| solves
+% the problem:\,\footnote{For instance, it will not work when the line is 
+%      automatically capitalized.}
+%
+% \begin{sample}
+% (With |\selectlanguage*{spanish}|)\\
+% |\section{\ensurelanguage Sobre la confecci'on de t'itulos}|
+% \end{sample}
+% In typeset, writing and other modes it's ignored.
+%
+% \begin{cmd}
+% |\ensuredcommand{<cmd>}{<text>}|
+% \end{cmd}
+% 
+% Saves the <text> in <cmd> so that you can
+% use it in a ``ensured'' form later. Neither |\selectlanguage| nor |\uselanguage|
+% can be passed in an argument---you must save the text with this command and then
+% release it. The language is the
+% current one. No arguments are allowed, and <text> is fragile, but
+% a construction like |\uselanguage{...}{\ensuredcommand...}| is valid.
+%
+% Spanish |\chaptername| uses a |\'i| which is not
+% set by standard |OT1| and hence is provided by |spanish.ot1|.
+% If you use |\chaptername| in a text with, say, the German |text|
+% group you will get an accented dotted i. In this
+% case, you can use |\ensuredcommand|.
+% 
+% \subsection{Extensions}
+%
+% The \textsf{polyglot} package provides \emph{extensions}
+% so that its functionality will be extended to and from
+% some package with the help of some commands
+% in the |polyglot.cfg| file,
+% sometimes with automatic loading. At the current moment,
+% only font enconding extensions
+% are implemented, which are automatically taken care of.
+% (In future releases, you will be allowed
+% to by-pass the current default settings, and add further extensions.)
+%
+% \subsubsection{Font Encoding Extensions}
+% 
+% With the help of this extension, you are allowed 
+% to change some commands depending of font
+% encodings. When a language is loaded, the package reads
+% automatically the files named |<language-file>.<ENC>|,
+% if they exist, where <language-file> is the exact name of the
+% file |.ld| which the language is defined in, and <ENC>
+% is the name of encodings declared. So, for instance, if you
+% have preinstalled |T1| (besides |OMS|, etc.) and:
+% \begin{sample}
+% |\documentclass{article}|\\
+% |\usepackage[LXX,OT1]{fontenc}|\\
+% |\usepackage[spanish,german]{polyglot}|
+% \end{sample}
+% the following files will be read \emph{if they exist} (if not, nothing
+% happens):
+% \begin{sample}
+% |spanish.t1   spanish.ot1  spanish.lxx  spanish.oms  |etc.\\
+% | german.t1    german.ot1   german.lxx   german.oms  |etc.
+% \end{sample}
+% So, for example, |german.ot1| redefines some umlauted vowels in order to
+% modify the accent position and to allow hyphenation.
+% 
+% Loading of these files may be inhibited by means of the option
+% |nofontenc| when calling \textsf{polyglot}:
+% \begin{sample}
+% |\usepackage[spanish,german,nofontenc]{polyglot}|
+% \end{sample}
+% 
+% \section{Developpers Commands}
+%
+% Some command names could seem inconsistent with that of the user commands. In
+% particular, when you refer to a language in a document you are referring in fact
+% to a dialect, which belogs to a language. As user, you cannot access to a 
+% language and you instead access to a dialect named like the language.
+% From now on, when we say ``current language'' we mean
+% ``current language or dialect.'' For more details on dialects, see below.
+%
+% \subsection{General}
+% 
+% \begin{cmd}
+% |\DeclareLanguage{<language>}|
+% \end{cmd}
+% 
+% The first command in the |.ld| must be this one. Files don't always
+% have the same name as the language, so this command makes things work.
+% 
+% \begin{cmd}
+% |\DeclareLanguageCommand{<cmd-name>}{<group>}[<num-arg>][<default>]{<definition>}|
+% \end{cmd}
+% 
+% Stores a command in a group of the current language. The definition will be
+% activated when the group is selected, and the old definition, if any,
+% will be stored for later recovery if the group is switched off.
+% 
+% There is a point to note (which applies also to the next commands).
+% Suppose the following code:
+% \begin{sample}
+% At |spanish.ld|:\\
+% |\DeclareLanguageCommand{\partname}{names}{Parte}|\\
+% | |\\
+% At document:\\
+% |\selectlanguage*{spanish}|\\
+% |\renewcommand{\partname}{Libro}|\\
+% |\selectlanguage*{english}|\\
+% |\partname|
+% \end{sample}
+% Obviously, at this point |\partname| is `Part'. But if you follow with
+% \begin{sample}
+% |\selectlanguage*{spanish}|\\
+% |\partname|
+% \end{sample}
+% Surprise! \emph{Your} value of |\partname|, i.e., `Libro', is recovered. So
+% you can customize easily these macros in your document, even if you switch
+% back and forth between languages.
+% 
+% \begin{cmd}
+% |\SetLanguageVariable{<var-name>}{<group>}{<value>}|
+% \end{cmd}
+% 
+% Here <var-name> stands for the internal name of a counter or a lenght as
+% defined by |\newconter| (|\c@...|) or |\newlenght|. The variable must be
+% already defined. When the group is selected, the new value will be assigned to
+% the variable, and the old one will be stored.
+% 
+% \begin{cmd}
+% |\SetLanguageCode{<code-cmd>}{<group>}{<char-num>}{<value>}|
+% \end{cmd}
+% 
+% Similar to |\SetLanguageVariable| but for codes. For instance:
+% \begin{sample}
+% |\SetLanguageCode{\sfcode}{text}{`.}{1000}|
+% \end{sample}
+%
+% Languages with |\frenchspacing| should set the |\sfcodes| with this command, so
+% that a change with |\nonfrenchspacing| is recovered after a switch.
+% 
+% \begin{cmd}
+% |\DeclareLanguageSymbolCommand{<char>}{<group>}[<num-arg>][<default>]{<definition>}|
+% \end{cmd}
+% 
+% First makes <char> active and then defines it just as
+% |\DeclareLanguageCommand| does.
+% 
+% For instance, in French:
+% \begin{sample}
+% |\DeclareLanguageSymbolCommand{:}{spacing}{\unskip\,:}|
+% \end{sample}
+% Note that this command \emph{does not} change the category yet,
+% and hence the previous command is valid. (Well, except if the |:|
+% is already active. If you want to avoid any infinite loop, you can just
+% say |{\unskip\,\string:}|).
+%
+% \begin{cmd}
+% |\UpdateSpecial{<char>}|
+% \end{cmd}
+%
+% Updates |\dospecials| and |\@sanitize|. First removes <char>
+% from both lists; then adds it if it has categorie
+% other than `other' or `letter'. With this method we avoid duplicated
+% entries, as well as removing a character being usually special (for
+% instance |~|).
+%
+% \subsection{Groups}
+%
+% \begin{cmd}
+% |\DeclareLanguageGroup{<group>}|\\
+% |\DeclareLanguageGroup*{<group>}|
+% \end{cmd}
+%
+% Adds a new group. With the starred version, the group will be
+% considered a |text| group, and hence included in the default
+% of |\selectlanguage|.  Group names cannot begin with |no|
+% because of the |no|-form convention given above.
+% 
+% \subsection{Ligatures}
+% 
+% \begin{cmd}
+% |\DeclareLigatureCommand{<char-1>}{<char-2>}{<definition>}|
+% \end{cmd}
+% 
+% Makes the pair |<char-1><char-2>| a shorthand for <definition>.
+% For instance:
+% \begin{sample}
+% |\DeclareLigatureCommand{"}{u}{\"u}|
+% \end{sample}
+% There are some points to note:
+% \begin{itemize}
+% \item Spaces between <char-1> and <char-2> are not significant. So
+% |"u| and \verb*=" u= will give the same result. Be careful then.
+% \item If <char-1> is followed by a char which there is no
+% ligature for, the original value (i.e., the value of <char-1> at
+% |\selectlanguage|) is used.
+%
+% \item If <char-1> is followed by an ``argument'' which is
+% empty or with more
+% than one token, its original value is also used. This is very important
+% in order to break ligatures. In German, you get `\,''und' with
+% |"{}und| or |"{und}|; in French, you get `C'est' with
+% |C'{}est| or |C'{est}|; in Spanish, you write 
+% a non-breaking space before `n' with |~{}n|, and before `\~n', with
+% |~{~n}| or |~~n|. If some package (there are in fact a lot) has defined,
+% say, |^| with  some special function which requires an argument,
+% this will be keept in most of cases (multi-token arguments), even
+% when we define |^| as a ligature; if the argument has only a token
+% you may trick the |^| with, say, |^{e{}}| (two tokens, `e' and
+% empty). In math mode, the original math meaning is used
+% (even if the |\mathcode| was |"8000|).
+%
+% \item Some languages, such as Spanish, make active \lc{} and \rc{} in
+% order to
+% declare the ligatures \lc\lc{} and \rc\rc{} for guillemets. If you define
+% macros testing some counters or lengths are lesser or greater,
+% load the package with option |loadonly| and select the language
+% after these commands.
+%
+% \item Any definitionn attached to a 
+% ligature char is preserved, even if not
+% currently `active'. This makes switching a language very
+% robust.\footnote{Don't try to change the catcode of a char to `other'
+%   before selecting a language
+%   in order to `lost' its definition---that won't work. Instead,
+%   let it to relax if you really need it.
+%   (In fact, \textsf{polyglot} uses three internal variables, the
+%   first storing the text value, the second the
+%   math value, and the third the definition, which is used
+%   when the catcode was `active' or the mathcode was |"8000|.)}
+%
+% \item Yet, an error is given 
+% when a ligature char has certain character codes
+% at the selection, namely
+% `escape' (|\|), `open' (|{|), `close' (|}|),
+% `return' (|^^M|) or `comment' (|%|).
+% This is a very unlikely situation and for the moment
+% there is nothing I can do. Furthermore, `invalid' chars
+% are validated (as `other') in the scope of the language.
+% \end{itemize}
+% 
+% \begin{cmd}
+% |\DeclareLigature{<char-1>}|
+% \end{cmd}
+% In some instances, you might wish to declare a ligature char before
+% |\DeclareLigatureCommand| (which has an implicit |\DeclareLigature|).
+% (I wonder when, but here it is.)
+%
+% \subsection{Dates}
+% 
+% \begin{cmd}
+% |\DeclareDateFunction{<date-function-name>}{<definition>}|\\
+% |\DeclareDateFunctionDefault{<date-function-name>}{<definition>}|\\
+% |\DeclareDateCommand{<cmd-name>}{<definition>}|
+% \end{cmd}
+% By means of |\DeclareDateCommand| you can define commands like |\today|. The
+% good news is that a special syntax is allowed in <definition> with date
+% functions called with \lc<date-funtion-name>\rc. Here
+% \lc<date-funtion-name>\rc{} stands for the definition given in
+% |\DeclareDateFunction| for the current language.  If no such function for
+% the language is given then the definition of |\DeclareDateFunctionDefault|
+% is used. See |english.ld| for a very illustrative example. (The 
+% \lc{} and \rc{} are  actual lesser and greater signs.)
+% 
+% Predeclared functions (with |\DeclareDateFunctionDefault|) are:
+% \begin{itemize}
+% \item \lc|d|\rc{} one or two digits day: 1, 2, \dots, 30, 31.
+% \item \lc|dd|\rc{} two digits day: 01, 02, \dots
+% \item \lc|m|\rc{} one or two digits month.
+% \item \lc|mm|\rc{} two digits month.
+% \item \lc|yy|\rc{} two digits year: 96, 97, 98, \dots
+% \item \lc|yyyy|\rc{} four digits year: 1996, 1997, 1998, \dots
+% \end{itemize}
+% 
+% Functions which are not predeclared, and hence should be declared
+% by the |.ld| file, are:
+% 
+% \begin{itemize}
+% \item \lc|www|\rc{} short weekday: mon., tue., wes., \dots
+% \item \lc|wwww|\rc{} weekday in full: Monday, Tuesday, \dots
+% \item \lc|mmm|\rc{} short month: jan., feb., mar., \dots
+% \item \lc|mmmm|\rc{} month in full: January, February, \dots
+% \end{itemize}
+% 
+% The counter |\weekday| (also |\value{weekday}|) gives a number between 1
+% and 7 for Sunday, Monday, etc.
+% 
+% For instance:
+% \begin{sample}
+% |\DeclareDateFunction{wwww}{\ifcase\weekday\or Sunday\or Monday\or|\\
+% |  Tuesday\or Wesneday\or Thursday\or Friday\or Saturday\fi}|\\
+% |\DeclareDateCommand{\weektoday}{|\lc|wwww|\rc
+%    |, |\lc|mmmm|\rc| |\lc|dd|\rc| |\lc|yyyy|\rc|}|
+% \end{sample}
+% 
+% \subsection{Dialects}
+%
+% As stated above, |\selectlanguage| access to dialects rather than 
+% languages. |\DeclareLanguage| declares both a language and a dialect
+% with the same name, and selects the actual language.
+%
+% \begin{cmd}
+% |\DeclareDialect{<dialect>}|\\
+% |\SetDialect{<dialect>}|\\
+% |\SetLanguage{<language>}|
+% \end{cmd}
+%
+% |\DeclareDialect| declares a dialect, which shares all
+% of declarations for the current actual language.
+% With |\SetDialect| you set the dialect so that new declarations
+% will belong only to
+% this dialect. |\DeclareDialect| just declares but does not set it.
+% 
+% A dialect with the same name as the language is always implicit.
+% You can handle this dialect exactly as any other dialect.
+% In other words, after setting the dialect, new 
+% declarations belong only to this one. If you want to return to the
+% actual language, so that
+% new declarations will be shared by all dialects, use |\SetLanguage|.
+%
+% Note that commands and variables declared for a language are
+% set by |\selectlanguage| before those of dialects,
+% doesn't matter the order you declared it.
+%
+% For example:
+% \begin{sample}
+% |\DeclareLanguage{english}|\\
+% |\DeclareDialect{american}|\\
+% Declarations\\
+% |\SetDialect{english}|\\
+% |\DeclareDateCommmand{\today}{...}|\\
+% |\SetDialect{american}|\\
+% |\DeclareDateCommand{\today}{...}|\\
+% |\SetLanguage{english}|\\
+% More declarations shared by both |english| and |american|
+% \end{sample}
+%
+% \subsection{Font Encoding}
+% 
+% \begin{cmd}
+% |\DeclareLanguageCompositeCommand{<cmd>}{<encoding>}{<letter>}|%
+%                                 |[<arg-num>][<default>]{<definition>}|\\
+% |\DeclareLanguageTextCommand{<cmd>}{<encoding>}|%
+%                            |[<arg-num>][<default>]{<definition>}|
+% \end{cmd}
+% 
+% The equivalent to |\DeclareTextCompositeCommand|
+% and |\DeclareTextCommand| in this package. (That's
+% all.) New values are
+% stored in the |text| group. No default versions are provided;
+% default values may be assigned to the |?| encoding.
+% 
+% A typical file looks like:
+% \begin{sample}
+% |\ProvidesFile{spanish.ot1}|\\
+% |\def\spanish@acute#1{\allowhyphens\accent19 #1\allowhyphens}|\\
+% |\DeclareLanguageCompositeCommand{\'}{OT1}{a}{\spanish@acute a}|\\
+% |\DeclareLanguageCompositeCommand{\'}{OT1}{A}{\spanish@acute A}|\\
+% (And so on.)
+% \end{sample}
+% 
+% You may add files
+% for your local encodings, and you can modify the files supplied
+% with the package (mainly for |OT1|) provided you state clearly at
+% their beginning the changes and does not distribute them as part of
+% the \textsf{polyglot} package.
+%
+% We note a very important point here. Perhaps |\DeclareLanguageCompositeCommand|
+% change the internal definition of <cmd> which is not recovered after
+% you exit from a language. You will not notice that in a document at all, but if
+% you are trying to access to the original value you must do it before
+% selecting the language for the first time.
+% Yet, if <cmd> has a particular definition declared for
+% this language, the old value \emph{will} be restored, as you can expect.
+% 
+% |\PreLoadLanguage| loads
+% these files always, but you cannot
+% |\PreLoadLanguage|s with these encoding extensions for encoding schemes
+% not preloaded. (As far as \LaTeX\ is concerned, they don't
+% exist yet!) If you want them, there are two tactics:
+% \begin{enumerate}
+% \item  Preloading the encoding in the corresponding |.cfg|
+% \LaTeXe\ file. Then both encoding a the language extensions to it are
+% directly available in your \LaTeX\ instalation.
+% \item Accepting the fact these files
+% will be loaded when typesetting the
+% document.
+% \end{enumerate}
+% In order to avoid a new loading, you must
+% move the files preloaded to a folder where \LaTeX\ cannot find them.
+% 
+% \subsection{Interaction with Classes}
+%
+% \begin{cmd}
+% |\pg@no<group>|\\
+% (i.e. |\pg@nonames|, |\pg@nolayout|, |\pg@noligatures|, etc.)
+% \end{cmd}
+%
+% Initially, these commands are not defined, but if they are, the
+% corresponding groups are not loaded. This mechanism is intended
+% for classes designed for a certain publication and with a
+% very concrete layout which we don't want to be changed.
+% You simply write in the class file
+% \begin{sample}
+% |\newcommand{\pg@nolayout}{}|
+% \end{sample} 
+% Note this procedure does not ever load the group---if
+% you select it nothing happens.
+%
+% \section{Configuration}
+% 
+% There \emph{must} be a file called |polyglot.cfg| which will define the
+% configuration for your system. This file consists of two parts, the first
+% one being used by the installation procedure, and the second one mainly by
+% |\usepackage|. When compilling \LaTeX, you must load in some point the file
+% |polyglot.ltx| if you want to install hyphenation patterns other than
+% English.
+% 
+% \begin{cmd}
+% |\PreLoadPatterns{<patterns>}{<hyphens-file>}|
+% \end{cmd}
+% Defines a new language with the patterns in <hyphens-file>. Internally,
+% these languages will be referred to as |\pgh@<language>|. 
+% 
+% \begin{cmd}
+% |\PreLoadLanguage{<language>}[<file>]{<patterns>}{<more>}|
+% \end{cmd}
+% Loads a language \emph{at the time of installation} so that the
+% language has not to be read by |\usepackage|. Even more, if you only
+% want preloaded languages, you needn't call |polyglot.sty| in your
+% document at all. The file read is |<file>.ld|
+% or, if no optional argument, |<language>.ld|; and <patterns> has to be any
+% set preloaded with |\PreLoadPatterns|. This command also preloads
+% |polyglot.def|. In the part <more> you may insert commands just between
+% the loading of the |.ld| file and  the
+% final settings made by the command.
+%
+% In running
+% time, this command is ignored.
+% 
+% \begin{cmd}
+% |\PreLoadPolyGlot|
+% \end{cmd}
+% Preloads |polyglot.def|, so that the style is directly available
+% in your system.
+% 
+% \begin{cmd}
+% |\LoadLanguage{<language>}[<file>]{<patterns>}{<more>}|
+% \end{cmd}
+% Quite similar to |\PreLoadLanguage| but in running time (i.e., when read
+% with |\usepackage|). In installation time
+% this command is ignored.
+% 
+% \begin{cmd}
+% |\LanguagePath{<file-path>}|
+% \end{cmd}
+% 
+% Add a path to |\input@path|. (See |ltdirchk| and the
+% \emph{Local Guide} for details.) If \textsf{polyglot} has been installed,
+% this command will be ignored in running time. 
+% 
+% This is a tipical |polyglot.cfg|:
+% \begin{sample}
+% |\PreLoadPatterns{english}{hyphen.tex}|\\
+% |\PreLoadPatterns{spanish}{sphyph.tex}|\\
+% | |\\
+% |\LoadLanguage{english}{english}|\\
+% |\LoadLanguage{spanish}{spanish}|\\
+% |\LoadLanguage{german}{english}|\\
+% |\LoadLanguage{austrian}[german]{english}|\\
+% |\LoadLanguage{french}{spanish}|
+% \end{sample}
+%
+% \section{Installation}
+%
+% If you want install the package in your basic \LaTeX\ configuration,
+% follow these steps:
+% \begin{enumerate}
+% \item First, run |polyglot.ins|. The files |polyglot.sty|,
+% |polyglot.ltx|, |polyglot.def| and |polyglot.cfg| are generated.
+% \item Create a file named |hyphen.cfg| which has to include the line
+% \begin{sample}
+% |\input{polyglot.ltx}|
+% \end{sample}
+% You may also rename |polyglot.ltx| as |hyphen.cfg|.
+% \item Move the package and hyphen files where \LaTeX\ can find them.
+% \item Modify |polyglot.cfg| following your requirements. At this
+% stage, only |\LanguagePath|, |\PreLoadPatterns|, |\PreLoadPolyGlot|,
+% and |\PreLoadLanguage| are mandatory, provided you want them and you
+% won't remove nor modify later at all the |\PreLoadLanguage| commands.
+% (Once installed
+% you are allowed to add |\LoadLanguage|s to this file freely.)
+% \item Run |latex.ltx|.
+% \item If installation didn't failed, remove |polyglot.ltx| and
+% |polyglot.def| as they are no longer needed.
+% \end{enumerate}
+%
+% \section{Customization}
+%
+% ``Well, but I dislike |spanish.ld|.''
+% You can customize easily a language once
+% loaded, with new commands or by redefininig the existing ones. 
+% \begin{itemize}
+% \item If want to redefine a language command, simply select the
+% group of this language which defines it
+% (as with |\selectlanguage*|) and then
+% redefine it with |\renewcommand|.
+% \item If, in turn, you want to define a
+% new command for a language, first
+% make sure no language is selected
+% (for instance, with |\unselectlanguage|).
+% Then |\SetLanguage| and use the declaration
+% commands provided by the
+% package and described above.
+% \end{itemize}
+%
+% A further step is creating a new file,
+% by copying it, modifying the commands
+% and, of course, renaming the file! Or with
+% a file with extension |.ld| as:
+% \begin{sample}
+% |\ProvidesFile{...ld}|\\
+% |\input{...ld} | the file you want customize\\
+% |\selectlanguage*{...}|\\
+% Commands to be redefined\\
+% |\unselectlanguage|\\
+% |\SetLanguage{...}|\\
+% Commands to be created
+% \end{sample}
+% Then, add a line to |polyglot.cfg| with |\LoadLanguage|...
+%
+% \section{Errors}
+%
+% \begin{cmd}
+% |Unknown group|
+% \end{cmd}
+% 
+% You are trying to assign a command to an inexistent group.
+% Perhaps you have misspelled it.
+%
+% \begin{cmd}
+% |Missing language file|
+% \end{cmd}
+%
+% Probable causes:
+% \begin{itemize}
+% \item Wrong configuration, |\PreLoadLanguage|
+%       instead of |\LoadLanguage| with a language
+%       not preloaded.
+%
+% \item The corresponding |.ld| file is missing.
+%
+% \item Wrong path.
+% \end{itemize}
+%
+% \begin{cmd}
+% |Unknown language|
+% \end{cmd}
+%
+% You forgot requesting it. Note that dialects
+% stand apart from languages; i.e., you have no
+% access to |austrian| just requesting |german|.
+%
+% \begin{cmd}
+% |Invalid option skipped|
+% \end{cmd}
+%
+% In the starred version of |\selectlanguage|
+% you must use the |no|-forms only.
+%
+% \begin{cmd}
+% |Bad ligature|
+% \end{cmd}
+%
+% A very unlikely error which is generated by a bug in the
+% description file of the current
+% language, but also if some package has changed some categories
+% to very, very extrange values.
+%
+% \begin{cmd}
+% |Bug found (<n>)|
+% \end{cmd}
+%
+% You will only find this error when using
+% the developpers commands---never with the user ones---or if
+% there is a bug in description files
+% written by others. In the latter case, contact
+% with the author. The meaning of the parameter <n> is
+% \begin{enumerate}
+% \item \emph{Unknown group in declaration.} The group hasn't been
+%       declared. Perhaps you misspelled it.
+%
+% \item \emph{Invalid group name.} Group names cannot begin
+%        with |no| to avoid mistakes when disabling a group.
+%
+% \item \emph{Declaration clash.} You are trying to
+%       redeclare a command or to set a new
+%       value to a variable for this language.
+%       If you want redefine it, select the language and simply
+%       use |\renewcommand| (or |\set..|).
+%       If you intend to define a new command
+%       for the language, sorry, you must change its name.
+%
+% \item \emph{Invalid language/dialect setting.} Generated by
+%       |\SetLanguage| or |\SetDialect| when the argument is not
+%       a declared language/dialect.
+% \end{enumerate}
+% 
+% Now we describe how polyglot generates \TeX{} 
+% and \LaTeX{} errors because of intrinsic syntax
+% problems.
+%
+% \begin{cmd}
+% |Argument of \pg@text@ligature has an extra }|
+% \end{cmd}
+% 
+% An usual problem with ligatures because the second
+% letter is taken as a macro argument. If the first
+% letter, for instance |"| in German, is followed
+% by a |}| then |TeX| gets confused. For instance,
+% \begin{sample}
+% (Current language is German in full.)\\
+% |\uselanguage[date]{english}{\emph{``\today"}}|
+% \end{sample}
+%
+% Note that German ligatures are active. Fix:
+% type |{}| just after |"|. (A ligature just before
+% the closing |}| in |\uselanguage| is OK.)
+%
+% \begin{cmd}
+% |TeX capacity exceeded, sorry [save_size=<n>]|
+% \end{cmd}
+%
+% You are using to many ungrouped languages.
+% Fix: use the environment version of |selectlanguage|
+% or alternatively use |\unselectlanguage| before
+% a new |\selectlanguage|.
+%
+% \section{Conventions}
+% 
+% I strongly encourage the following conventions:
+% \begin{itemize}
+% \item Concerning dates, see above.
+%
+% \item There must be a main ligature, which will precede some special
+% features. For instance, the obvious main ligature in German is |"|, and
+% so we have \verb=""=, |"-|, |"ck|, etc.
+%
+% \item Default values for encodings, in the |.ld| file. 
+%
+% \item A mandatory convention. The language names must consist of
+% lowercase letters.
+% 
+% \item Don't name your own language files with the name of some language.
+% I'd like to reserve these to official descriptions,
+% supported by myself or a group.
+% \end{itemize}
+%
+% \section{Languages}
+% 
+% Now follows a brief description of the languages provided. All of them
+% include the group |names| and |\today| in |date|.
+% 
+% \subsection{\texttt{american}}
+% 
+% |english| dialect. Same as English with date in American format.
+% 
+% \subsection{\texttt{austrian}}
+% 
+% |german| dialect. Same as German with ``January'' in Austrian.
+% 
+% \subsection{\texttt{english}}
+% 
+% \begin{description}
+% \item[date] Functions \lc|ddd|\rc{} (ordinal date), \lc|mmm|\rc,
+% \lc|mmmm|\rc{}, \lc|www|\rc{} and \lc|wwww|\rc.
+% \item[tools] |\arabicth{<counter>}|: ordinal form of <counter>.
+% \end{description}
+% 
+% \subsection{\texttt{french}}
+% 
+% \begin{description}
+% \item[date] Functions \lc|ddd|\rc{} (ordinal first), 
+% \lc|mmmm|\rc{} and \lc|wwww|\rc{}.

+% |^e|, |^i|, |^o|, |^u|, |"y|, |"e| and |/c| (also uppercase).
+% Composite letters |"ae| and |"oe| (also uppercase).
+% Guillemets with automatic
+% spacing \lc\lc{} and \rc\rc. 
+% \item[text] |OT1| guillemets and accents. Spaces before
+% double punctuation signs. French spacing.

+% abbreviations.
+% \end{description}
+% 
+% \subsection{\texttt{german}}
+% 
+% \begin{description}
+% \item[date] Functions \lc|mmm|\rc,
+% \lc|mmm|\rc, \lc|www|\rc{} and \lc|wwww|\rc.
+% \item[ligatures] Accents |"a|, |"e|, |"i|, |"o|,
+% |"u| (also uppercase). Scharfes s |"s| and |"S|.
+% Hyphenation |"ck|, |"ff|, |"ll|, etc. German quotes
+% |"`| and |"'|. Guillemets |"|\lc{} and |"|\rc. Other |"-|,
+% {\ttfamily\string"\string|} and |""|.
+% \item[text] |OT1| guillemets, german quotes and accents 
+% (with lower umlauts in a, o and u). 
+% \end{description}
+% 
+% \subsection{\texttt{spanish}}
+% 
+% A new group |math| is defined for some functions names: |\lim|
+% giving l\'\i m, |\tg|, etc.
+% 
+% \begin{description}
+% \item[date] Functions \lc|mmm|\rc,
+% \lc|mmmm|\rc, \lc|www|\rc{} and \lc|wwww|\rc.
+% \item[layout] |itemize| with |---|. |enumerate| with ``1.'',
+% ``\emph{a})'', ``1)'', ``\emph{a}$'$)''. |\fnsymbol|
+% produces one, two, three\ldots{} asteriscs. |\alpha|
+% includes the letter ``\~n''.
+% \item[ligatures] Accents |'a|, |'e|, |'i|, |'o|,
+% |'u|, |"u|, |'c| (\c{c}), |~n| $=$ |'n| (also uppercase).
+% Hyphenation |'rr| and |'-|.
+% \item[text] |OT1| guillemets and accents. French
+% spacing. Space before |\%|.
+% \item[tools] |\sptext{<text>}|: small and raised text for
+% abbreviations (the preceptive dot is included). |\...|
+% for ellipsis.
+% \end{description}
+% 
+% \section{Comming soon}
+% 
+% \begin{itemize}
+% \item More extension facilities.
+%
+% \item Time, besides date, will be supported.
+%
+% \item Multiple ligatures (with three or more chars).
+%
+% \item Ligatures in index entries, which will
+% provide automatic ``alphabetize as''.
+% (By expanding, say, French |"oeil| into
+% |oeil@\oe il| or a similar
+% device.)
+%
+% \item Plain \TeX\ compatibility. (Not a priority.)
+%
+% \item Modularity, so that only required commands will be loaded. (Since this
+% is one of the goals of \LaTeX3, is very unlikely I implement this
+% point before the release of the new \LaTeX.)
+%
+% \item Releasing of unnecessary commands, if required. (For example, if
+% you are going to use just a language.)
+%
+% \item More languages. (My goal is not to provide a large set of language files
+% but rather a set of tools for users---\TeX{} groups in particular.
+% I will answer to people asking for help, and of course 
+% contributions will be credited.)
+%
