%
%  \section{The French language}
%
%    The file \file{\filename}\footnote{The file described in this
%    section has version number \fileversion\ and was last revised on
%    \filedate.}, derived from \file{frenchy.sty}, defines all
%    the language definition macros for the French language.
%
%    Customization for the French language is achieved following the
%    book ``Lexique des r\`egles typographiques en usage \`a
%    l'Imprimerie nationale'' troisi\`eme \'edition (1994),
%    ISBN-2-11-081075-0.
%
%    This file has been designed to be used with \LaTeXe, \LaTeX-2.09
%    and Plain\TeX{} formats. If you are still using \LaTeX-2.09, you
%    \emph{should} consider switching to \LaTeXe!
%
%    The command |\selectlanguage{french}| switches to the French
%    language%
%    \footnote{\texttt{\textbackslash selectlanguage\{francais\}}
%    and \texttt{\textbackslash selectlanguage\{frenchb\}} are kept
%    for backward compatibility but should no longer be used.},
%    with the following effects:
%    \begin{enumerate}
%    \item French hyphenation patterns are made active;
%    \item `double punctuation' is made active for correct spacing
%          in French;
%    \item |\today| prints the date in French;
%    \item the caption names are translated into French
%          (\LaTeX{} only);
%    \item the default items in itemize environment are set to `--'
%          instead of \textbullet, and all vertical spacing and glue
%          is deleted, a hook to reset standard \LaTeX{} spacing
%          is provided (|\FrenchItemizeSpacingfalse|);
%          it is possible to change `--' to something else (`---'
%          for instance) by redefining |\FrenchLabelItem|;
%          apart from the global hook |\FrenchLabelItem|, it is
%          also possible to change the `labelitems' at any level
%          (1 to 4) in French, using the standard \LaTeX{} syntax,
%          for instance: |\renewcommand{\labelitemii}{\textbullet}|;
%          in order to be effective in French, the redefinitions
%          have to be made when French is the current language
%          (i.e.\ \emph{after} the |\begin{document}|), the changes are
%          saved when switching to another language and will be
%          remembered of, when switching back to French;
%    \item vertical spacing in general \LaTeX{} lists is
%          shortened, a hook to reset standard \LaTeX{} settings
%          is provided (|\FrenchListSpacingfalse|) ;
%    \item the first paragraph of each section is indented
%          (\LaTeX{} only);
%    \item the space after |\dots| is removed in French.
%    \end{enumerate}
%
%    Some commands are provided in |frenchb| to make typesetting
%    easier:
%    \begin{enumerate}
%    \item French quotation marks can be entered using the commands
%          |\og| and |\fg| which work in \LaTeXe, \LaTeX-2.09 and
%          Plain\TeX{}, their appearance depending on what is
%          available to draw them; if you use \LaTeXe{} \emph{and}
%          |T1|-encoding you can also enter them as
%          |<<~French quotation marks~>>| but then
%          \emph{don't forget} the unbreakable spaces, (|\og| and
%          |\fg| provide for correct line breaks and better
%          horizontal spacing).
%          |\og| and |\fg| can be used outside French, they provide
%          then English quotes `` and ''.
%    \item A command |\up| is provided to typeset superscripts like
%          |M\up{me}| (abbreviation for ``Madame''), |1\up{er}| (for
%          ``premier'').
%    \item Family names should be typeset in small capitals and never
%          be hyphenated, the macro |\bsc| (boxed small caps) does
%          this, e.g., |Leslie~\bsc{Lamport}| will produce
%          Leslie~\mbox{\textsc{Lamport}}.
%    \item Commands |\primo|, |\secundo|, |\tertio| and |\quarto|
%          may be used to enumerate in lists.
%    \item Abbreviations for ``Num\'ero'' and ``num\'ero'' are
%          obtained via the commands |\No|, |\no|.
%    \item Two commands are provided to typeset the symbol for
%          ``degr\'e'': |\degre| prints the raw character and
%          |\degres| should be used to typeset temperatures (e.g.,
%          ``|20~\degres C|'' with an unbreakable space), or for
%          alcohols' strengths (e.g., ``|45\degres|'' with \emph{no}
%          space in French).
%    \item In math mode the comma has to be surrounded with
%          braces to avoid a spurious space being inserted after it,
%          in decimal numbers for instance (see the \TeX{}book p.~134).
%          The command |\DecimalMathComma| makes the comma be an
%          ordinary character \emph{in French only} (no space added);
%          as a counterpart, if |\DecimalMathComma| is active, an
%          explicit space has to be added in lists and intervals:
%          |$[0,\ 1]$|, |$(x,\ y)$|. |\StandardMathComma| switches back
%          to the standard behaviour of the comma.
%    \item A command |\nombre| is provided to easily typeset numbers:
%          it works both in text and in math mode: inputting
%          |\nombre{3141,592653}| will format this number properly
%          according to the current language (French or non-French):
%          each slice of three digits will be separated either with
%          a comma in English or with a space in French (if you prefer
%          a thin space instead of a normal space, just add the command
%          |\ThinSpaceInFrenchNumbers| to the preamble of your document,
%          or to |frenchb.cfg|).
%          The command |\nombre| is a contribution of Vincent Jalby
%          using ideas of David Carlisle in comma.sty.
%    \item |frenchb| has been designed to take advantage of the |xspace|
%          package if present: adding |\usepackage{xspace}| in the
%          preamble will force macros like |\fg|, |\ier|, |\ieme|,
%          |\dots|, \dots, to respect the spaces you type after them,
%          for instance typing `|1\ier juin|' will print
%          `1\textsuperscript{er} juin' (no need for a forced space
%          after |1\ier|).
%    \item Two commands, |\FrenchLayout| and |\StandardLayout| (to be
%          used \emph{only in the preamble}) are provided to unify the
%          layout of multilingual documents (it mainly concerns lists)
%          regardless the current language (see section~\ref{sec-global}
%          for details).
%    \item Two commands |\AddThinSpaceBeforeFootnotes| and
%          |\FrenchFootnotes| enable to customize the layout of
%          footnotes following the French IN's specifications;
%          the first one, which can only be used \emph{before} the
%          |\begin{document}|, adds a thinspace in the running text
%          before the number or symbol calling the footnote; the
%          second one modifies the footnote's layout: it typesets
%          leading numbers as `1.\hspace{.5em}' instead of
%          `$\hbox{}^1$'. |\FrenchFootnotes| has no effect on footnotes
%          numbered with symbols (as in the |\thanks| command).
%
%          None of these commands are active by default, both can
%          be best added to |frenchb.cfg| or to the preamble of the
%          document. |\FrenchFootnotes| and |\StandardFootnotes|,
%          which cancels the effect of |\FrenchFootnotes| for the
%          text coming next, can be used anywhere in the document.
%          The command |\StandardFootnotes| may be useful when
%          some footnotes are numbered with letters (inside minipages
%          for instance).
%
%          |\AddThinSpaceBeforeFootnotes| and |\FrenchFootnotes| act
%          on \emph{all} footnotes whatever the current language is.
%    \end{enumerate}
%
%    \vspace{\baselineskip}
%    All commands previously available in |francais.ldf| have been
%    included in |frenchb.ldf| for compatibility, sometimes with
%    updated definitions.
%
%    The |french| package, by Bernard~\textsc{Gaulle}, was not
%    designed to run with \babel\ (although the latest versions claim
%    to be \babel\ compatible), but rather as a stand-alone package
%    for the French language.
%    It provides many more functionalities (like |\lettrine|,
%    |\sommaire|\dots) not available in |frenchb|,
%    at the cost of a much greater complexity and possible
%    incompatibilities with other languages.
%
%    As |french| is known to produce the best layout available for
%    French typography, I have borrowed many ideas from Bernard's file.
%    I did my best to help users of both packages (|french| and
%    |frenchb|) to exchange their sources files easily (see the example
%    configuration file below in section~\ref{sec-cfg}), with one
%    exception which affects the way French quotation marks are
%    entered: |frenchb| uses \emph{macros} (|\og| and |\fg|) while
%    |french| uses active characters (|<<| and |>>|).
%
%    \vspace{\baselineskip}
%    French typographic rules specify that some white space should be
%    present before `double punctuation' characters. These characters
%    are |;| |!| |?| and |:|.
%    In order to get this white space automatically, the category code
%    of these characters is made |\active|. In French, the user
%    \emph{should} input these four characters preceded with a space,
%    but as many people forget about it (even among native French
%    writers!), the default behaviour of |frenchb| is to automatically
%    add a |\thinspace| before `|;|' `|!|' `|?|' and a normal
%    (unbreakable) space before~`|:|' (this is the rule in French
%    typography).  It's up to the user to add or not a space
%    \emph{after} `double punctuation' characters: usually a space is
%    necessary, but not always (before a full point or a closing brace
%    for instance), so this cannot done automatically.
%
%    In (rare) cases where no space should be added before a `double
%    punctuation', either use |\string;| |\string:| |\string!|
%    |\string?| instead of |;| |:| |!| |?|, or switch locally to
%    English.  For instance you can type |C\string:TEX| or
%    |\begin{otherlanguage}{english}{C:TEX}\end{otherlanguage}| to
%    avoid the space before~|:| in a MS-DOS path.
%
%    Some users dislike this automatic insertion of a space before
%    `double punctuation', and prefer to decide themselves whether a
%    space should be added or not; so a hook |\NoAutoSpaceBeforeFDP|
%    is provided: if this command is added (in file |frenchb.cfg|, or
%    anywhere in a document) |frenchb| will respect your typing, and
%    introduce a suitable space before `double punctuation' \emph{if
%    and only if} a space is typed in the source file before those
%    signs.
%
%    The command |\AutoSpaceBeforeFDP| switches back to the
%    default behaviour of |frenchb|.
%
%    \vspace{\baselineskip}
%    Once you have built your format, a good precaution would be to
%    perform some basic tests about hyphenation in French. For
%    \LaTeXe{} I suggest this:
%    \begin{itemize}
%    \item run the following file, with the encoding suitable for
%      your machine (\textit{my-encoding} will be |latin1| for
%      \textsc{unix} machines and PCs running~Windows, |applemac|
%      for Macintoshs, or |cp850| for PCs running~DOS). \\[3mm]^^A\]
%      |%%% Test file for French hyphenation.|\\
%      |\documentclass{article}|\\
%      |\usepackage[|\textit{my-encoding}|]{inputenc}|\\
%      |\usepackage[T1]{fontenc} % Use EC fonts for French|\\
%      |%\usepackage{aeguill}    % Uncomment this line and|\\
%      |                         % comment out the preceeding one|\\
%      |                         % to use AE virtual fonts.|\\
%      |\usepackage[francais]{babel}|\\
%      |\begin{document}|\\
%      |\showhyphens{signal container \'ev\'enement alg\`ebre}|\\
%      |\showhyphens{|\texttt{signal container \'ev\'enement
%                     alg\`ebre}|}|\\
%      |\end{document}|
%    \item check the hyphenations proposed by \TeX{} in your log-file;
%      in French you should get with both 7-bit and 8-bit encodings\\
%      \texttt{si-gnal contai-ner \'ev\'e-ne-ment al-g\`ebre}.\\
%      Do not care about how accented characters are displayed in the
%      log-file, what matters is the position of the `|-|' hyphen
%      signs \emph{only}.
%    \end{itemize}
%    If they are all correct, your installation (probably) works fine,
%    if one (or more) is (are) wrong, ask a local wizard to see what's
%    going wrong and perform the test again (or e-mail me about what
%    happens).\\
%    Frequent mismatches:
%    \begin{itemize}
%    \item you get |sig-nal con-tainer|, this probably means that the
%    hyphenation patterns you are using are for US-English, not for
%    French;
%    \item you get no hyphen at all in \texttt{\'ev\'e-ne-ment}, this
%    probably means that you are using CM fonts and the macro
%    |\accent| to produce accented characters.
%    Using EC fonts with built-in accented characters or Ml\TeX{}
%    with CM fonts avoids this type of mismatch.
%    \end{itemize}
%
%    \vspace{\baselineskip}
%    |frenchb| has been improved using helpful suggestions from many
%    people, the main contributions came from Vincent~Jalby.
%    Thanks to all of them!
%
%  \subsection*{Changes}
%
%    First version released: 1.1 as of 1996/05/31 part of
%    \babel-3.6beta.
%
%    \textbf{Changes in version 1.1b}: update for \babel-3.6.
%
%    \textbf{Changes in version 1.2}: new command |\nombre| to
%    format numbers; removed command |\fup| borrowed from the
%    |french| package (|\up| does a better job in \LaTeXe);
%    also removed aliases |\french| and |\english| (frenchb.cfg
%    is a better place for these).
%
%    \textbf{Changes in version 1.3}:
%    \begin{itemize}
%      \item The `xspace' package, when present, now controls
%            spacing after all (sensible) macros, formerly `xspace'
%            worked on |\fg| (suggested by Vincent~Jalby);
%      \item spacing after opening and before closing guillemets
%            improved as suggested by Thierry~Bouche;
%      \item a replacement for poor looking guillemets in OT1 encoding
%            (\emph{math} fonts are used to emulate them) is provided
%            if the file |ot2wncyr.fd| is found: this file defines an
%            OT2 encoding using AMS Cyrillic fonts; these
%            have built-in guillemets, they are \emph{text} fonts,
%            are free, and are distributed as METAFONT and Type1 fonts
%            (good for pdftex!), the replacement was suggested by
%            G\'erard~Degrez; if the files |ot2wncyr.fd|, |wncy*.mf|,
%            |wncy*.tfm|, and |wncy*.pfb| aren't available on your
%            system, you \emph{should} get them from \mbox{CTAN};
%            if your system complains about missing |wncy*.tfm| fonts,
%            it means your \TeX{} system is \emph{incomplete}, as a
%            quick fix, you can either remove |ot2wncyr.fd| or add the
%            command |\LasyGuillemets| to the preamble of your document
%            or to |frenchb.cfg|, then |frenchb| will behave as it did
%            in the previous versions.\\
%            In case Cyrillic guillemets do not fit, it is possible
%            to pick French guillemets from any font using the
%            command |\FrenchGuillemetsFrom| which requires 4 arguments
%            |\FrenchGuillemetsFrom{|{\it coding}|}{|{\it font}\relax
%            |}{|{\it char-left}|}{|{\it char-right}|}|, for instance,
%            add |\FrenchGuillemetsFrom{T1}{ppl}{19}{20}| to the
%            preamble of your document or to |frenchb.cfg|, to pick
%            French guillemets from Palatino (fontname=ppl, char 19
%            and 20 are left and right guillemets in T1-encoding).
%            This was suggested by Michel~Bovani.
%      \item the environment `itemize' has been redesigned in French
%            according to specifications from Jacques~Andr\'e
%            and Thierry~Bouche; it is possible to switch back to the
%            settings of version~1.2: add |\FrenchItemizeSpacingfalse|
%            \emph{after} loading |frenchb| in the preamble (this can
%             be useful to process old documents);
%      \item two switches have been added to go back to standard
%            \LaTeX{} list spacing |\FrenchItemizeSpacingfalse|
%            and |\FrenchListSpacingfalse|;
%      \item |\nombre| now properly handles signs in \LaTeXe;
%      \item definition of |\dots| changed in French;
%      \item in French, with the standard \LaTeX{} classes, captions
%            in figures and tables are printed with an endash instead
%            of a colon.
%    \end{itemize}
%
%    \textbf{Changes in version 1.4}:
%    \begin{itemize}
%      \item the redefinition of|\@makecaption| is changed not to
%         overwrite the changes made by some classes (koma-script,
%         amsart, ua-thesis\dots) as pointed out by Werner~Lemberg;
%      \item a hook, |\FrenchGuillemetsFrom|, is provided to pick
%          French guillemets from any font (suggested by
%          Michel~Bovani, works \emph{only} in OT1-encoding);
%      \item a hook, |\FrenchLabelItem|, is provided to enable marks
%          other than `--' (|\textendash|) in French lists
%          (also suggested by Michel~Bovani);
%      \item |\DecimalMathComma|, |\StandardMathComma|,
%        |\ThinSpaceInFrenchNumbers| added;
%      \item |\FrenchLayout| and |\StandardLayout| added;
%      \item an example of customization file |frenchb.cfg| is
%          included in |frenchb.dtx|.
%    \end{itemize}
%
%    \textbf{Changes in version 1.5}:
%    \begin{itemize}
%      \item The settings for spacing in French lists are no longer
%         tuned at the |\@trivlist| level but within |\list|; this
%         enables the users to provide their own settings for the
%         lists they define with |\list| (suggested by P. Pichaureau).
%         Although the layout of the standard lists
%         \emph{has not changed}, some lists, based directly on
%         |\@trivlist| or |\trivlist|, could possibly be typeset
%          differently when upgrading from version 1.4 to 1.5.
%         The command |\FrenchOldTrivlisttrue| could then, be useful
%         to process older documents.
%      \item Apart from the global hook |\FrenchLabelItem|, it is
%         now also possible to change the `labelitems' at any level
%         (1 to 4) in French, using the standard \LaTeX{} syntax,
%         for instance: |\renewcommand{\labelitemii}{\textbullet}|.
%      \item The internal name for the French language has been
%         changed from |frenchb| to |french|, it means that
%         |\captionsfrench|, |\datefrench|, |\extrasfrench|,
%         |\noextrasfrench|, are to be used now instead of
%         |\captionsfrenchb|, |\datefrenchb|, |\extrasfrenchb|,
%         |\noextrasfrenchb|.
%      \item From version 1.5f on, it is possible to customize
%         the space inserted before a colon in French; its default
%         value is |\space| (as in previous versions of |frenchb|),
%         but it can now be changed to |\thinspace| by redefining
%         |\Fcolonspace|.
%    \end{itemize}
%
%    \textbf{Changes in version 1.6}:
%    \begin{itemize}
%      \item Two new commands are provided:
%         |\AddThinSpaceBeforeFootnotes| and |\FrenchFootnotes|;
%         they enable to typeset footnotes according to the
%         French IN's specifications (suggested by Jacques~Andr\'e).
%      \item |frenchb| will make use of |\textdegree| (TS1 encoding)
%         to typeset degrees whenever possible.
%      \item Default guillemets have been changed \emph{in OT1
%         encoding only} in version~1.6c: the former ones were picked
%         up in the wncyr fonts, which forced the cyrillic encoding to
%         OT2 when \babel{} was loaded with option |frenchb| before a
%         cyrillic language (|russian|, |ukrainian| or |bulgarian|).
%         Now, LM fonts for T1-encoding are available, we pick up the
%         guillemets from them, for OT1-encoding.
%      \item The config file |frenchb.cfg| is now loaded only when
%         \LaTeXe{} is used (from version~1.6g).
%      \item The command |\degres| now works also in math mode (from
%         version~1.6g), but not in bold versions (it is a text 
%         character basically).

%  \subsection{Punctuation}
%
%    The `double punctuation' characters (|;| |!| |?| and |:|) have to
%    be made |\active| for an automatic control of the amount of space
%    to insert before them.
%    \begin{macrocode}
\initiate@active@char{:}
\initiate@active@char{;}
\initiate@active@char{!}

%    We specify that the French group of shorthands should be used.
%    \begin{macrocode}
\expandafter\addto\csname extras\CurrentOption\endcsname{%

%    These characters are `turned on' once, later their definition may

%    \end{macrocode}
%
%    One more thing |\extrasfrench| needs to do is to make sure that
%    |\frenchspacing| is in effect.  If this is not the case the
%    execution of |\noextrasfrench| will switch it off again.

%
% \changes{frenchb-1.6c}{2003/06/30}{OT1 `Polish' guillemets are
%     now taken from the LM fonts which will be part of TL8.}
%
%    EC/LM fonts and standard PostScript fonts have built-in
%    guillemets, we of course use them.  CM fonts have no French
%    guillemets built-in, so we have to emulate them:
%    \begin{itemize}
%      \item if a file `t1lmr.fd' is found, we expect the LM fonts
%        to be present on the system, so we pick up French guillemets
%        from them; before version 1.6b, French guillemets were
%        borrowed from the `wncyr' fonts, this has been changed because
%        it resulted in a conflict with the russian option of \babel.
%        Former Cyrillic guillemets are still available through the
%        command |\CyrillicGuillemets| (for backward compatibility).
%      \item otherwise we use math symbols, either \LaTeX's `lasy' font
%        if available, or \TeX{}~symbols |\ll| and |\gg| otherwise;
%    \end{itemize}
%
%    The standard names for French quotation marks are |\guillemotleft|
%    and |\guillemotright|, these commands are defined in |t1enc.def|
%    for T1-encoding.
%    In \LaTeXe{} formats, we first define these commands for
%    OT1-encoding (for CM fonts), using either the Polish `pl*' fonts
%    or \LaTeX{}'s `lasy' fonts.
%    Other local text encodings \emph{should} define them too,
%    but if they don't, the OT1 definitions will be used.
%    The standard PostScript fonts should \emph{always} be used together
%    with T1-encoding (\emph{not} OT1), for proper hyphenation and
%    built-in (better looking) French quotation marks.
%
% \changes{frenchb-1.2b}{1997/04/24}{Spacing after opening and before

%    inhibit hyphenation, nothing like \cs{allowhyphens} is required.}
%
%    The next step is to provide correct spacing after |\guillemotleft|
%    and before |\guillemotright| : a space precedes and follows
%    quotation marks but no line break is allowed neither \emph{after}
%    the opening one, nor \emph{before} the closing one.

%  \begin{macro}{\bbl@frenchlistspacing}
%  \begin{macro}{\bbl@nonfrenchlistspacing}
%    Vertical spacing in general lists should be shorter in French
%    texts than the defaults provided by \LaTeX.
%    Note that the easy way, just changing values of vertical spacing
%    parameters when entering French and restoring them to their
%    defaults on exit would not work; as most lists are based on
%    |\list| we will redefine |\list| (up to version~1.4, the more
%    internal command |\@trivlist| was redefined, this ensured that
%    all lists would have common settings, but didn't allow the users
%    to provide their own settings, as pointed out by P.~Pichaureau).
%    If standard LaTeX{} settings are preferred, it is easy to issue
%    the command |\FrenchListSpacingfalse| in the preamble or in
%    |frenchb.cfg|. Please note that changing the flag
%    |\FrenchListSpacing| will \emph{not} take effect immediately,
%     but next time language French is switched on.
%
%    The amount of vertical space before and after a list is given by
%    |\topsep| + |\parskip| (+ |\partopsep| if the list starts a new
%    paragraph). IMHO, |\parskip| should be added \emph{only} when
%    the list starts a new paragraph, so I subtract |\parskip| from
%    |\topsep| and add it back to |\partopsep|; this will normally
%    make no difference because |\parskip|'s default value is 0pt, but
%    will be noticeable when |\parskip| is \emph{not} null.\\
%    Of course, this code is only for \LaTeX.

%    Checking the book ``Lexique des r\`egles typographiques en usage
%    \`a l'Imprimerie nationale'' confirmed their points, so the itemize
%    environment has been totally redefined for French in version~1.3.
%
%    Several people pointed out to me that the layout of lists can
%    either be set by the current language or be tuned independently of
%    the language as part of the layout of the document. So hooks should
%    be provided to switch off the special settings made in |frenchb|.
%    Setting |\FrenchItemizeSpacingfalse| \emph{after} loading |frenchb|
%    in the preamble switches back to settings of version~1.2 (this can
%    be useful to process old documents). If you want all list spacings
%    to be exactly what they are in standard \LaTeXe{}, then add also
%    |\FrenchListSpacingfalse| in the preamble \emph{after} loading
%    |frenchb|. Both switches can also be set in |frenchb.cfg|.
%    Please note that changing the flags |\FrenchItemizeSpacing| and
%    |\FrenchListSpacing| will \emph{not} take effect immediately,
%    but next time language French is switched on.
%
%    The \textbullet{} is never used in French itemize-lists,
%    a long dash `--' is preferred for all levels. The item label used
%    in French is stored in |\FrenchLabelItem}|, it defaults to '--' and
%    can be changed using |\renewcommand| (see the example
%    configuration file above).

%
%    In English the decimal part starts with a point and thousands
%    should be separated by a comma: an approximation of $1000\pi$
%    should be inputed as |$3{,}141.592{,}653$| in math mode and

%    In French the decimal part starts with a comma and thousands
%    should be separated by a space; the same approximation of
%    $1000\pi$ should be inputed as |$3\;141{,}592\;653$| in math mode
%    and as something like |3~141,592~653| in text: in math mode, the
%    comma is of type |\mathpunct| (thus normally followed by a space)
%    while the point is of type |\mathord| (no space added).
%
%    Thierry Bouche suggested that a second type of comma, of type
%    |\mathord| would be useful in math mode, and proposed to
%    introduce a command (named |\decimalsep| in this package),
%    the expansion of which would depend on the current language.
%
%    Vincent Jalby suggested a command |\nombre| to conveniently
%    typeset numbers: inputting |\nombre{3141,592653}| either in
%    text or in math mode will format this number properly according
%    to the current language (French or non-French).
%
%    |\nombre| accepts an optional argument which happens to be
%    useful with the package `dcolumn', it specifies the decimal
%    separator used in the \emph{source code}:
%    |\newcolumntype{d}{D{,}{\decimalsep}{-1}}| \\
%    |\begin{tabular}{|d|}\hline    |    \\

%    |\end{tabular}                 |    \\
%    will print a column of numbers aligned on the decimal point

%    \LaTeXe's standard definition of |\dots| in text-mode is
%    |\textellipsis| which includes a |\kern| at the end;
%    this space is not wanted in some cases (before a closing brace
%    for instance) and |\kern| breaks hyphenation of the next word.
%    We define |\Frtextellipsis| for French (in \LaTeXe{} only).

%    The |\if| construction in the \LaTeXe{} definition of |\dots|
%    doesn't allow the use of |xspace| (|xspace| is always followed

%  \subsection{Global layout}
%  \label{sec-global}
%
% \changes{frenchb-1.4}{1999/10/03}{Added this section.}
%
%    In multilingual documents, some typographic rules must depend
%    on the current language (e.g., hyphenation, typesetting of
%    numbers, spacing before double punctuation\dots),
%    others should, IMHO, be kept global to the document:
%    especially the layout of lists (see~\ref{sec-lists})
%    and the indentation of the first paragraph of sections
%    (see~\ref{sec-indent}).
%
%  \begin{macro}{\FrenchLayout}
%  \begin{macro}{\StandardLayout}
%    In a multilingual document, a unified look, either the French
%    one or the standard one, can be assigned to the whole document:
%    adding |\FrenchLayout| will give a global ``French look'' to
%    the document (e.g., lists, regardless the current language, will
%    be typeset as in French) and |\StandardLayout| forces a global
%    ``US-English'' look.
%    Both of these commands can only be used \emph{before} the
%    |\begin{document}|.
%    |\StandardLayout| can also be of interest for class designers
%    who do not want |frenchb| to interfere with their global layout
%    choices.
%
%    As of version~1.4, |\FrenchLayout| and |\StandardLayout| only
%    affect:
%    \begin{itemize}
%      \item the layout of lists (see~\ref{sec-lists}),
%      \item the indentation of the first paragraph of sections
%        (see~\ref{sec-indent}).

%  \subsection{Extra utilities}
%
%    All that is left to do now is to provide the French user
%    with some extra utilities.
%
%  \begin{macro}{\up}
%  \begin{macro}{\ieme}
%    |\up| eases the typesetting of superscripts like
%    `1\raise0.55ex\hbox{\small er}'.  |\up| relies on
%    |\textsuperscript| when available (i.\,e., in \LaTeXe).
%
% \changes{frenchb-1.1}{1996/01/20}{Use \cs{textsuperscript} in \LaTeXe,
%    as suggested by Vincent Jalby.}
%
% \changes{frenchb-1.1}{1996/01/26}{Internal macro \cs{up@size}
%    introduced by Johannes Braams to replace \cs{small},
%    too fragile in 2.09).}
%
% \changes{frenchb-1.1}{1996/05/03}{\cs{@ptsize} may not be undefined,
%    i.\,e. in slides.cls.}
%
%  \begin{macro}{\up@size}
%    The internal macro |\up@size| holds the size at which the
%    superscript will be typeset. The reason for this is that we have
%    to specify it differently for different formats.
%    \begin{macrocode}
\ifx\sevenrm\@undefined
  \ifx\@ptsize\@undefined
    \let\up@size\small
  \else
    \ifx\selectfont\@undefined
%    \end{macrocode}
%    In this case the format is the original \LaTeX-2.09:
%    \begin{macrocode}
      \ifcase\@ptsize
        \let\up@size\ixpt\or
        \let\up@size\xpt\or
        \let\up@size\xipt
      \fi
%    \end{macrocode}
%    When |\selectfont| is defined we probably have NFSS available:
%    \begin{macrocode}
    \else
      \ifcase\@ptsize
        \def\up@size{\fontsize\@ixpt{10pt}\selectfont}\or
        \def\up@size{\fontsize\@xpt{11pt}\selectfont}\or
        \def\up@size{\fontsize\@xipt{12pt}\selectfont}
      \fi
    \fi
  \fi
\else
%    \end{macrocode}
%    If we end up here it must be a plain based \TeX{} format, so:
%    \begin{macrocode}
    \let\up@size\sevenrm
\fi
%    \end{macrocode}
%  \end{macro}
%    Now we can define |\up|. When \LaTeXe{} runs in
%    compatibility mode (\LaTeX-2.09 emulation), |\textsuperscript| is
%    also defined, but does no good job, so we give two different
%    definitions for |\up| using |\if@Two@E|.
%    \begin{macrocode}
\if@Two@E
  \DeclareRobustCommand*{\up}[1]{\textsuperscript{#1}}
\else
  \DeclareRobustCommand*{\up}[1]{\leavevmode\raise1ex\hbox{\up@size#1}}
