%  \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.}, defines all the language definition macros for the
%    French language.
%
%    Customisation 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.
%
%    First version released: 1.1 (1996/05/31) as part of
%    \babel-3.6beta.
%
%    |frenchb| has been improved using helpful suggestions from many
%    people, mainly from Jacques Andr\'e, Michel Bovani, Thierry Bouche,
%    and Vincent Jalby.  Thanks to all of them!
%
%    This new version (2.x) has been designed to be used with \LaTeXe{}
%    and Plain\TeX{} formats only.  \LaTeX-2.09 is no longer supported.
%    Changes between version 1.6 and \fileversion{} are listed in
%    subsection~\ref{ssec-changes} p.~\pageref{ssec-changes}.
%
%    An extensive documentation is available in French here:\\
%    \url{http://daniel.flipo.free.fr/frenchb}
%
%  \subsection{Basic interface}
%
%    In a multilingual document, some typographic rules are language
%    dependent, i.e.\ spaces before `double punctuation' (|:| |;| |!|
%    |?|) in French, others concern the general layout (i.e.\ layout of
%    lists, footnotes, indentation of first paragraphs of sections) and
%    should apply to the whole document.
%
%    Starting with version~2.2, |frenchb| behaves differently according
%    to \babel's \emph{main language} defined as the \emph{last}
%    option\footnote{Its name is kept in \texttt{\textbackslash
%           bbl@main@language}.} at \babel's loading.  When French is
%    not \babel's main language, |frenchb| no longer alters the global
%    layout of the document (even in parts where French is the current
%    language): the layout of lists, footnotes, indentation of first
%    paragraphs of sections are not customised by |frenchb|.
%
%    When French is loaded as the last option of \babel, |frenchb|
%    makes the following changes to the global layout, \emph{both in
%    French and in all other languages}\footnote{%
%       For each item, hooks are provided to reset standard
%       \LaTeX{} settings or to emulate the behavior of former versions
%       of \texttt{frenchb} (see command
%       \texttt{\textbackslash frenchbsetup\{\}},
%       section~\ref{ssec-custom}).}:
%    \begin{enumerate}
%    \item the first paragraph of each section is indented
%          (\LaTeX{} only);
%    \item the default items in itemize environment are set to `---'
%          instead of `\textbullet', and all vertical spacing and glue
%          is deleted; it is possible to change `---' to something else
%          (`--' for instance) using |\frenchbsetup{}|;
%    \item vertical spacing in general \LaTeX{} lists is
%          shortened;
%    \item footnotes are displayed ``\`a la fran\c{c}aise''.
%    \end{enumerate}
%
%    Regarding local typography, 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%\footnote{Actually, they are active in the whole
%           document, only their expansions differ in French and
%           outside French.} for correct spacing in French;
%    \item |\today| prints the date in French;
%    \item the caption names are translated into French
%          (\LaTeX{} only).  The separator following the table or
%          figure number in captions is printed as ` -- ' in French
%          instead of `: ', this setting can be changed by redefining
%          |\CaptionSeparator| for French and |\CaptionSeparatorORI|
%          for other languages.
%    \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 and Plain\TeX,
%          their appearance depending on what is available to draw
%          them; even if you use \LaTeXe{} \emph{and} |T1|-encoding,
%          you should refrain from entering them as
%          |<<~French quotation marks~>>|: |\og| and |\fg| provide
%          better horizontal spacing.
%          |\og| and |\fg| can be used outside French, they typeset
%          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'').  Other commands are also provided for
%          ordinals: |\ier|, |\iere|, |\iers|, |\ieres|, |\ieme|,
%          |\iemes| (|3\iemes| prints 3\textsuperscript{es}).
%    \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}}.  Note that composed names
%          (such as Dupont-Durant) may now be hyphenated on explicit
%          hyphens, this differs from |frenchb|~v.~1.x.
%    \item Commands |\primo|, |\secundo|, |\tertio| and |\quarto|
%          print 1\textsuperscript{o}, 2\textsuperscript{o},
%          3\textsuperscript{o}, 4\textsuperscript{o}.
%          |\FrenchEnumerate{6}| prints 6\textsuperscript{o}.
%    \item Abbreviations for ``Num\'ero(s)'' and ``num\'ero(s)''
%          (N\textsuperscript{o} N\textsuperscript{os}
%          n\textsuperscript{o} and n\textsuperscript{os}~)
%          are obtained via the commands |\No|, |\Nos|, |\no|, |\nos|.
%    \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| was provided in 1.x versions to easily
%          format numbers in slices of three digits separated either
%          by a comma in English or with a space in French; |\nombre|
%          is now mapped to |\numprint| from \file{numprint.sty}, see
%          \file{numprint.pdf} for more information.
%    \item |frenchb| has been designed to take advantage of the
%          \file{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|).
%    \end{enumerate}
%
%  \subsection{Customisation}
%  \label{ssec-custom}
%
%     Up to version 1.6, customisation of |frenchb| was achieved
%     by entering commands in \file{frenchb.cfg}.
%     Version 2.0 introduced a new command |\frenchbsetup{}| using
%     the \file{keyval} syntax which should make it easier to choose
%     among the many options available.  The command |\frenchbsetup{}|
%     is to appear in the preamble only (after loading \babel).
%     Usage of a \file{frenchb.cfg} file for customisation \emph{should
%     definitely be avoided}.
%
%     \vspace{.5\baselineskip}
%     |\frenchbsetup{ShowOptions}| prints all available options to
%     the \file{.log} file, it is just meant as a remainder of the
%     list of offered options.  As usual with \file{keyval} syntax,
%     boolean options (as |ShowOptions|) can be entered as
%     |ShowOptions=true| or just |ShowOptions|, the `|=true|' part
%     can be omitted.
%
%     \vspace{.5\baselineskip}
%     The other options are listed below.  Their default value is
%     shown between brackets, sometimes followed be a `\texttt{*}'.
%     The `\texttt{*}' means that the default shown applies when
%     |frenchb| is loaded as the \emph{last} option of \babel{}
%     ---\babel's \emph{main language}---, and is toggled otherwise:
%     \begin{itemize}
%     \item |StandardLayout=true [false*]| forces |frenchb| not to
%       interfere with the layout: no action on any kind of lists,
%       first paragraphs of sections are not indented (as in English),
%       no action on footnotes.  This option replaces the former
%       command |\StandardLayout|.  It might be used to avoid conflicts
%       with classes or packages which customise lists or footnotes.
%     \item |GlobalLayoutFrench=false [true*]| can be used, when French
%       is the main language, to emulate what prior versions of
%       |frenchb| (pre-2.2) did: lists, and first paragraphs
%       of sections will be displayed the standard way in other
%       languages than French, and ``\`a la fran\c{c}aise'' in French.
%       Note that the layout of footnotes is language independent
%       anyway (see below |FrenchFootnotes| and |AutoSpaceFootnotes|).
%       This option replaces the former command |\FrenchLayout|.
%     \item |ReduceListSpacing=false [true*]|; |frenchb| reduces the
%       values of the vertical spaces used in the \emph{all} list
%       environments in French (this includes itemize, enumerate,
%       description, but also abstract, quote, quotation and verse and
%       possibly others).  Setting this option to |false|
%       reverts to the standard settings of |list|.  This option
%       replaces the former command |\FrenchListSpacingfalse|.
%     \item |ListOldLayout=true [false]|; starting with version~2.6a,
%       the layout of lists has changed regarding leftmargins' sizes
%       and default itemize label (`---' instead of `--' up to~2.5k).
%       This option, provided for backward compatibility, displays
%       lists as they were up to version~2.5k.
%     \item |CompactItemize=false [true*]|; should no longer be used
%       (kept only for backward compatibility).
%     \item |StandardItemizeEnv=true [false*]|; |frenchb| redefines
%       the |itemize| environment to suppress any vertical space
%       between items of |itemize| lists in French and customise
%       leftmargins.  Setting this option to |false| reverts to the
%       standard definition of |itemize|.
%     \item |StandardEnumerateEnv=true [false*]|; starting with
%       version~2.6 |frenchb| redefines the |enumerate| and
%       |description| environments to make leftmargins match those of
%       the French version of |itemize| lists.  Setting this option to
%       |false| reverts to the standard definition of |enumerate| and
%       |description|.
%     \item |StandardItemLabels=true [false*]| when set to |true| this
%       option stops |frenchb| from changing the labels in |itemize|
%       lists in French.
%     \item |ItemLabels=\textendash|, |\textbullet|, |\ding{43}|,
%       \dots, |[\textemdash*]|; when |StandardItemLabels=false| (the
%       default), this option enables to choose the label used in
%       |itemize| lists for all levels.  The next three options do
%       the same but each one for one level only.  Note that the
%       example |\ding{43}| requires |\usepackage{pifont}|.
%     \item |ItemLabeli=\textendash|, |\textbullet|, |\ding{43}|,
%       \dots,|[\textemdash*]|
%     \item |ItemLabelii=\textendash|, |\textbullet|, |\ding{43}|,
%       \dots, |[\textemdash*]|
%     \item |ItemLabeliii=\textendash|, |\textbullet|, |\ding{43}|,
%       \dots, |[\textemdash*]|
%     \item |ItemLabeliv=\textendash|, |\textbullet|, |\ding{43}|,
%       \dots, |[\textemdash*]|
%     \item |StandardLists=true [false*]| forbids |frenchb| to
%       customise any kind of list.  Try the option |StandardLists|
%       in case of  conflicts with classes or packages that customise
%       lists too.  This option is just a shorthand for all four options
%       |ReduceListSpacing=false|, |StandardItemizeEnv=true|,
%       |StandardEnumerateEnv=true| and |StandardItemLabels=true|.
%     \item |IndentFirst=false [true*]|; |frenchb| normally forces
%       indentation of the first paragraph of sections.
%       When this option is set to |false|, the first paragraph of
%       will look the same in French and in English (not indented).
%     \item |FrenchFootnotes=false [true*]| reverts to the standard
%       layout of footnotes.  By default |frenchb| typesets leading
%       numbers as `1.\hspace{.5em}' instead of `$\hbox{}^1$', but
%       has no effect on footnotes numbered with symbols (as in the
%       |\thanks| command).  The former commands |\StandardFootnotes|
%       and |\FrenchFootnotes| are still there, |\StandardFootnotes|
%       can be useful when some footnotes are numbered with letters
%       (inside minipages for instance).
%     \item |AutoSpaceFootnotes=false [true*]|; by default |frenchb|
%       adds a thin space in the running text before the number or
%       symbol calling the footnote.  Making this option |false|
%       reverts to the standard setting (no space added).
%     \item |FrenchSuperscripts=false [true]|; then
%       |\up=\textsuperscript| (option added in version 2.1).
%       Should only be made |false| to recompile older documents.
%       By default |\up| now relies on |\fup| designed to produce
%       better looking superscripts.
%     \item |AutoSpacePunctuation=false [true]|; in French, the user
%       \emph{should} input a space before the four characters `|:;!?|'
%       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 recommended by
%       the French Imprimerie nationale).  This is convenient in most
%       cases but can lead to addition of spurious spaces in URLs or in
%       MS-DOS paths but only if they are no typed using |\texttt| or
%       verbatim mode.  When the current font is a monospaced
%       (typewriter) font, |AutoSpacePunctuation| is locally switched
%       to |false|, no spurious space is added in that case, so the
%       default behaviour of of |frenchb| in that area should be fine
%       in most circumstances.
%
%       Choosing |AutoSpacePunctuation=false| will ensure that
%       a proper space will be added before `|:;!?|' \emph{if and only
%       if} a (normal) space has been typed in.  Those who are unsure
%       about their typing in this area should stick to the default
%       option and type |\string;| |\string:| |\string!| |\string?|
%       instead of |;| |:| |!| |?| in case an unwanted space is
%       added by |frenchb|.
%     \item |ThinColonSpace=true [false]| changes the normal
%       (unbreakable) space added before the colon `:' to a thin space,
%       so that the same amount of space is added before any of the
%       four double punctuation characters.  The default setting is
%       supported by the French Imprimerie nationale.
%     \item |LowercaseSuperscripts=false [true]|; by default |frenchb|
%       inhibits the uppercasing of superscripts (for instance when they
%       are moved to page headers).  Making this option |false|
%       will disable this behaviour (not recommended).
%     \item |PartNameFull=false [true]|; when true, |frenchb| numbers
%       the title of |\part{}| commands as ``Premi\`ere partie'',
%       ``Deuxi\`eme partie'' and so on.  With some classes which change
%       the|\part{}| command (AMS and SMF classes do so), you will get
%       ``Premi\`ere partie~I'', ``Deuxi\`eme partie~II'' instead;
%       when this occurs, this option should be set to |false|,
%       part titles will then be printed as ``Partie I'', ``Partie II''.
%     \item |SuppressWarning=true [false]|; when true |frenchb| issues
%       no warnings if |\@makecaption| has been redefined or if the
%       \file{bigfoot} package is in use.
%     \item |og=|\texttt{\guillemotleft}, |fg=|\texttt{\guillemotright};
%       when guillemets characters are available on the keyboard
%       (through a compose key for instance), it is nice to use them
%       instead of typing |\og| and |\fg|.  This option tells |frenchb|
%       which characters are opening and closing French guillemets
%       (they depend on the input encoding), then you can type either
%       \texttt{\guillemotleft{} guillemets \guillemotright}, or
%       \texttt{\guillemotleft{}guillemets\guillemotright} (with or
%       without spaces), to get properly typeset French quotes.
%       This option requires \file{inputenc} to be loaded with the
%       proper encoding, it works with 8-bits encodings (latin1,
%       latin9, ansinew,  applemac,\dots) and multi-byte encodings
%       (utf8 and utf8x).
%     \end{itemize}
%
%  \subsection{Hyphenation checks}
%  \label{ssec-hyphen}
%
%    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, |ansinew| for PCs running~Windows,
%      |applemac| or |latin1| for Macintoshs, or |utf8|\dots\\[3mm]^^A\]
%      |%%% Test file for French hyphenation.|\\
%      |\documentclass{article}|\\
%      |\usepackage[|\textit{my-encoding}|]{inputenc}|\\
%      |\usepackage[T1]{fontenc} % Use LM fonts|\\
%      |\usepackage{lmodern}     % for French|\\
%      |\usepackage[frenchb]{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 8-bits fonts with built-in accented characters avoids
%    this kind of mismatch.
%    \end{itemize}

%    \textbf{Options' order} -- Please remember that options are read
%    in the order they appear inside the |\frenchbsetup| command.
%    Someone wishing that |frenchb| leaves the layout of lists
%    and footnotes untouched but caring for indentation of first
%    paragraph of sections could choose
%    |\frenchbsetup{StandardLayout,IndentFirst}| and get the expected
%    layout.  Choosing |\frenchbsetup{IndentFirst,StandardLayout}|
%    would not lead to the expected result: option |IndentFirst| would
%    be overwritten by |StandardLayout|.
%
%  \subsection{Changes}
%  \label{ssec-changes}
%
%  \subsubsection*{What's new in version 2.0?}
%
%    Here is the list of all changes:
%    \begin{itemize}
%    \item Support for \LaTeX-2.09 and for \LaTeXe{} in compatibility
%      mode has been dropped.  This version is meant for \LaTeXe{} and
%      Plain based formats (like \file{bplain}).  \LaTeXe{} formats
%      based on ml\TeX{} are no longer supported either (plenty of
%      good 8-bits fonts are available now, so T1 encoding should
%      be preferred for typesetting in French).  A warning is issued
%      when OT1 encoding is in use at the |\begin{document}|.
%    \item Customisation should now be handled only by command
%      |\frenchbsetup{}|, \file{frenchb.cfg} (kept for compatibility)
%      should no longer be used.  See section~\ref{ssec-custom} for
%      the list of available options.
%    \item Captions in figures and table have changed in French: former
%      abbreviations ``Fig.'' and ``Tab.'' have been replaced by full
%      names ``Figure'' and ``Table''.  If this leads to formatting
%      problems in captions, you can add the following two commands to
%      your preamble (after loading \babel) to get the former captions\\
%      |\addto\captionsfrench{\def\figurename{{\scshape Fig.}}}|\\
%      |\addto\captionsfrench{\def\tablename{{\scshape Tab.}}}|.
%    \item The |\nombre| command is now provided by the \file{numprint}
%      package which has to be loaded \emph{after} \babel{} with the
%      option |autolanguage| if number formatting should depend on the
%      current language.
%    \item The |\bsc| command no longer uses an |\hbox| to stop
%      hyphenation of names but a |\kern0pt| instead.  This change
%      enables \file{microtype} to fine tune the length of the
%      argument of |\bsc|; as a side-effect, compound names like
%      Dupont-Durand can now be hyphenated on  explicit hyphens.
%      You can get back to the former behaviour of |\bsc| by adding\\
%      |\renewcommand*{\bsc}[1]{\leavevmode\hbox{\scshape #1}}|\\
%      to the preamble of your document.
%    \item Footnotes are now displayed ``\`a la fran\c caise'' for the
%      whole document, except with an explicit\\
%      |\frenchbsetup{AutoSpaceFootnotes=false,FrenchFootnotes=false}|.\\
%      Add this command if you want standard footnotes.  It is still
%      possible to revert locally to the standard layout of footnotes
%      by adding |\StandardFootnotes| (inside a |minipage| environment
%      for instance).
%    \end{itemize}
%
%  \subsubsection*{What's new in version 2.1?}
%
%      New command |\fup| to typeset better looking superscripts.
%      Former command |\up| is now defined as |\fup|, an option
%      |\frenchbsetup{FrenchSuperscripts=false}| is provided for
%      backward compatibility.  |\fup| was designed using ideas from
%      Jacques Andr\'e, Thierry Bouche and Ren\'e Fritz, thanks to them!
%
%  \subsubsection*{What's new in version 2.2?}
%
%      Starting with version~2.2a, |frenchb| alters the layout of
%      lists, footnotes, and the indentation of first paragraphs of
%      sections) \emph{only if} French is the ``main language''
%      (i.e. babel's last language option).  The layout is global for
%      the whole document: lists, etc.\ look the same in French and in
%      other languages, everything is typeset ``\`a la fran\c caise''
%      if French is the ``main language'', otherwise |frenchb| doesn't
%      change anything regarding lists, footnotes, and indentation of
%      paragraphs.
%
%  \subsubsection*{What's new in version 2.3?}
%
%      Starting with version~2.3a, |frenchb| no longer inserts spaces
%      automatically before `|:;!?|' when a typewriter font is in use;
%      this was suggested by Yannis Haralambous to prevent
%      spurious spaces in computer source code or expressions like
%      \texttt{C\string:/foo}, \texttt{http\string://foo.bar},
%      etc.  An option (|OriginalTypewriter|) is provided to get back
%      to the former behaviour of |frenchb|.
%
%      Another probably invisible change: lowercase conversion in
%      |\up{}| is now achieved by the \LaTeX{} command |\MakeLowercase|
%      instead of \TeX's |\lowercase| command.  This prevents error
%      messages when diacritics are used inside |\up{}| (diacritics
%      should \emph{never} be used in superscripts though!).
%
%  \subsubsection*{What's new in version 2.4?}
%
%      A new option |SuppressWarning| has been added (desactivated by
%      default) to suppress warnings if |\@makecaption| has been
%      redefined or if the \file{bigfoot} package is in use.
%
%      French hyphenation patterns are now coded in Unicode, see file
%      \file{hyph-fr.tex}.  Extra code has been added to deal with
%      hyphenation of the French ``apostrophe'' with XeTeX and LuaTeX
%      engines.
%
%      Better compatibility with the \file{enumitem} package.
%
%      When typewriter fonts are in use (hence in verbatim mode) no
%      space is added after `\guillemotleft' and before
%      `\guillemotright' when they are entered as characters
%      (see |\frenchbsetup|).
%
%  \subsubsection*{What's new in version 2.5?}
%
%      The main change is that active characters are no longer used
%      in French with (recent) Xe\TeX-based engines (they still are
%      with \TeX-based engines).  All the functionalities (automatic
%      insertion of missing spaces before |:;!?| or bare replacement
%      of typed spaces with suitable unbreabable ones, tuning of the
%      spaces width) remain available and the user interface is
%      unchanged.  The use of active characters is replaced by the
%      |\XeTeXinterchartoks| mechanism (adapted from the
%      \file{polyglossia} package).
%
%      A new command |\NoAutoSpacing| has been added.  It should be used
%      \emph{inside a group} instead of |\shorthandoff{;:!?}| whenever
%      active characters or automatic spacing of French punctuation or
%      quote characters conflict with other packages; it is designed to
%      work with \TeX- and Xe\TeX-based engines.
%
%      Bug corrections: |\frenchspacing| and |\nonfrenchspacing| are no
%      longer messed up by \file{frenchb.ldf}.
%
%  \subsubsection*{What's new in version 2.6?}
%
%      The way |frenchb| handles list environments has been completely
%      redesigned in version~2.6 due to a long standing bug affecting
%      enumerate lists inside itemize lists.  Horizontal indentation of
%      itemize, enumerate and description lists differs now from
%      previous versions, an option for backward compatibility is
%      provided: |\frenchbsetup{ListOldLayout}|.
%
%      |frenchb| is now compatible with the \file{paralist} package.
%
%      Regarding the layout of figures' and tables' captions, version
%      2.6c is now fully compatible with AMS and koma-script classes
%      and with \file{caption} and \file{floatrow} packages.
%      Starting with version 2.6c, the \file{frenchb.cfg} file is no
%      longer generated from \file{frenchb.dtx}, but it is still loaded
%      (if found) for backward compatibility.

%    The macro |\extrasfrench| will perform all the extra

%    The macro |\noextrasfrench| is used to cancel the actions of
%    |\extrasfrench|.\\
%    In French, character ``apostrophe'' is a letter in expressions
%    like |l'ambulance| (French  hyphenation patterns provide entries
%    for this kind of words).  This means that the |\lccode| of
%    ``apostrophe'' has to be non null in French for proper hyphenation
%    of those expressions, and has to be reset to null when exiting
%    French.
%
%  \begin{macro}{\ifFBunicode}
%  \begin{macro}{\ifFBLuaTeX}
%  \begin{macro}{\ifFBXeTeX}
%    French hyphenation patterns are now coded in Unicode, see file

%    Let's define three new `if': |\ifFBLuaTeX|, |\ifFBXeTeX| and
%    |\ifFBunicode| which will be true for XeTeX and LuaTeX engines
%    and false for 8-bits engines.

%  \subsection{Punctuation}
%  \label{sec-punct}
%
% \changes{v2.5a}{2010/08/10}{Punctation is no longer made active
%    with XeTeX-based engines.}
%
%    As long as no better solution is available, the `double
%    punctuation' characters (|;| |!| |?| and |:|) have to be made
%    |\active| for an automatic control of the amount of space to
%    insert before them.  Xe\TeX{} provides an alternative to active
%    characters and Lua\TeX{} will hopefully do so as well in the
%    (near?) future.
%
%    Before doing so, we have to save the standard definition of
%    |\@makecaption| (which includes two ':') to compare it later to
%    its definition at the |\begin{document}|.
%    \begin{macrocode}

%
%    According to the I.N.\ specifications, the `:' requires a normal
%    space before it, but some people prefer a |\thinspace| (just
%    like the other three).  We define |\FBcolonspace| to hold the
%    required amount of space (user customisable).  In case some users
%    are not satisfied with |\thinspace|'s width, it is also
%    customisable.

%
%    If |\XeTeXinterchartokenstate| is available, we use the

%    before the four characters |;| |!| |?| and |:|.  The basis of the
%    following code was borrowed from the polyglossia package, see
%    \file{gloss-french.ldf}.  We use the same mechanism for French
%    quotes (\texttt{\guillemotleft} and \texttt{\guillemotright}),
%    when automatic spacing for quotes is required by options
%    \texttt{og=} and \texttt{fg=} in |\frenchbsetup{}| (see
%    section~\ref{sec-keyval}).
%
%    For every character used in French text-mode (except spaces),
%    |\XeTeXcharclass| value must be 0.
%    |\XeTeXcharclass| value for spaces is assumed to be 255.
%    Otherwise, the spacing before the `double punctuation' characters
%    and inside quotes might not be correct.
%
%    We switch |\XeTeXinterchartokenstate| to 1 and change the
%    |\XeTeXcharclass| values of |;| |!| |?| |:| |(| |]|
%    \texttt{\guillemotleft} and \texttt{\guillemotright} when

%    the opening one, nor \emph{before} the closing one.
%    |\FBguill@spacing| which does the spacing, has been fine tuned by
%    Thierry Bouche.  French quotes (including spacing) are printed by
%    |\FB@og| and |\FB@fg|, the expansion of the top level commands

%
%    |\up| eases the typesetting of superscripts like
%    `1\textsuperscript{er}'.  Up to version 2.0 of |frenchb| |\up| was
%    just a shortcut for |\textsuperscript| in \LaTeXe, but several
%    users complained that |\textsuperscript| typesets superscripts
%    too high and too big, so we now define |\fup| as an attempt to
%    produce better looking superscripts.  |\up| is defined as |\fup|
%    but |\frenchbsetup{FrenchSuperscripts=false}| redefines |\up|
%    as |\textsuperscript| for compatibility with previous versions.
%
%    When a font has built-in superscripts, the best thing to do is
%    to just use them, otherwise |\fup| has to simulate superscripts
%    by scaling and raising ordinary letters.  Scaling is done using
%    package \file{scalefnt} which will be loaded at the end of
%    \babel's loading (|frenchb| being an option of babel, it cannot
%    load a package while being read).
%
%    \begin{macrocode}
\newif\ifFB@poorman
\newdimen\FB@Mht
\ifLaTeXe
  \AtEndOfPackage{\RequirePackage{scalefnt}}
%    \end{macrocode}
%    |\FB@up@fake| holds the definition of fake superscripts.
%    The scaling ratio is 0.65, raising is computed to put the top of
%    lower case letters (like `m') just under the top  of upper case
%    letters (like `M'), precisely 12\% down.  The chosen settings
%    look correct for most fonts, but can be tuned by the end-user
%    if necessary by changing |\FBsupR| and |\FBsupS| commands.
%
%    |\FB@lc| is defined as |\MakeLowercase| to inhibit the uppercasing
%    of superscripts (this may happen in page headers with the standard
%    classes but is wrong); |\FB@lc| can be redefined to do nothing
%    by option |LowercaseSuperscripts=false| of |\frenchbsetup{}|.

    }
%    \end{macrocode}
%    The only packages I currently know to take advantage of real
%    superscripts are a) \file{xltxtra} used in conjunction with
%    XeLaTeX and OpenType fonts having the font feature
%    'VerticalPosition=Superior' (\file{xltxtra} defines
%    |\realsuperscript| and |\fakesuperscript|) and b) \file{fourier}
%    (from version 1.6) when Expert Utopia fonts are available.
%
%    |\FB@up| checks whether the current font is a Type1 `Expert'
%    (or `Pro') font with real superscripts or not (the code works
%    currently only with \file{fourier-1.6} but could work with any
%    Expert Type1 font with built-in superscripts, see below), and
%    decides to use real or fake superscripts.
%    It works as follows: the content of |\f@family| (family name of
%    the current font) is split by |\FB@split| into two pieces, the
%    first three characters (`|fut|' for Fourier, `|ppl|' for Adobe's
%    Palatino, \dots) stored in |\FB@firstthree| and the rest stored
%    in |\FB@suffix| which is expected to be `|x|' or `|j|' for expert
%    fonts.
%    \begin{macrocode}
  \def\FB@split#1#2#3#4\@nil{\def\FB@firstthree{#1#2#3}%

%    (Fourier) or \file{t1ppl-sup.fd} (Palatino), etc.\ supposed to
%    define the subfamily (|fut-sup| or |ppl-sup|, etc.) giving access
%    to the built-in superscripts.  If the \file{.fd} file is not found
%    by |\IfFileExists|, |\FB@up| falls back on fake superscripts,
%    otherwise |\FB@suffix| is checked to decide whether to use fake or
%    real superscripts.

%
% \begin{macro}{\CaptionSeparator}
% \begin{macro}{\CaptionSeparatorORI}
%    Let's consider now captions in figures and tables.
%    In French, captions in figures and tables should be printed with
%    the number followed by endash (` -- '), never as `Figure 1:' which
%    is the default in standard \LaTeXe{} classes.
%
%    The standard definition of |\@makecaption| (e.g., the one provided
%    in article.cls, report.cls, book.cls which is frozen for \LaTeXe{}
%    according to Frank Mittelbach), has been saved in
%    |\STD@makecaption| before making `:' active
%    (see section~\ref{sec-punct}).  `AtBeginDocument' we compare it to
%    its current definition (some classes like koma-script classes,
%    AMS classes, ua-thesis.cls\dots change it).
%    If they are identical, |frenchb| just adds a hook called
%    |\FBCaption@Separator| to |\@makecaption|; |\FBCaption@Separator|
%    defaults to |\CaptionSeparatorORI| (`: ') as in the standard
%    |\@makecaption|, and will be changed to |\CaptionSeparator|
%    (` -- ') in French.
%
%    The \file{caption} and \file{floatrow} packages are compatible
%    with |frenchb| if they are loaded after babel (a warning is
%    printed in the .log file when they are loaded too early).
%
%    No warning is issued for AMS classes as their layout of captions
%    is compatible with French typographic standards.
%
%    With koma-script classes, frenchb customises |\captionformat| in
%    French and issues no warning.
%
%    When |\@makecaption| has been changed by another class
%    or package, a warning is printed in the .log file.

%
% \changes{v2.6a}{2013/01/30}{Bug correction: changing \cs{leftmargin}
%    cannot be done only for itemize-lists: it messes up
%    embedded enumerate lists.  Pointed out by Denis Bitouz\'e.
%    Lists have been completely redesigned in frenchb v.~2.6a.
%    An option for backward compatibility is provided.}
%
%  \begin{macro}{\listFB}
%  \begin{macro}{\listORI}
%  \begin{macro}{\FB@listVsettings}
%    Vertical spacing in 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; so we define the command
%    |\FB@listVsettings| to hold the settings to be used by
%    the French variant |\listFB| of |\list|. Note that switching
%    to |\listFB| reduces vertical spacing in \emph{all} environments
%    built on |\list|: |itemize|, |enumerate|, |description|, but also
%    |abstract|, |quotation|, |quote| and |verse|\dots{}
%
%    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.
%
%    |\endlist| is not redefined, but |\endlistORI| and |\endlistFB|
%    will be defined as |\endlist| `AtBeginDocument' for users
%    who define their own lists using |\listORI| or |\listFB|.

%    |\parskip| is of type `skip', its mean value only (\emph{not
%    the glue}) should be subtracted from |\topsep| and added to
%    |\partopsep|, so convert |\parskip| to a `dimen' using

%          |\FrenchLabelItem}|, it defaults to `---' and can be changed
%          using |\frenchbsetup{}| (see section~\ref{sec-keyval}).
%      \item Vertical spacing between items, before and after
%         the list, should be \emph{null} with \emph{no glue} added;
%      \item In French the labels of itemize-lists are vertically
%         aligned as follows:\\
%          \fbox{\parbox[t]{.5\textwidth}{%
%            \parindent=1.5em

%
%    The \file{bigfoot} package deeply changes the way footnotes are
%    handled.  When \file{bigfoot} is loaded, we just warn the user
%    that |frenchb| will drop the customisation of footnotes.
%
%    The layout of footnotes is controlled by two flags
%    |\ifFBAutoSpaceFootnotes| and |\ifFBFrenchFootnotes| which are
%    set by options of |\frenchbsetup{}| (see section~\ref{sec-keyval}).
%    Notice that the layout of footnotes \emph{does not depend} on the
%    current language (just think of two footnotes on the same page
%    looking different because one was called in a French part, the
%    other one in English!).
%
%    When |\ifFBAutoSpaceFootnotes| is true, |\@footnotemark| (whose
%    definition is saved at the |\begin{document}| in order to include
%    any customisation that packages might have done) is redefined to
%    add a thin space before the number or symbol calling a footnote
%    (any space typed in is removed first).  This has no effect on
%    the layout of the footnote itself.

%    We then define |\@makefntextFB|, a variant of |\@makefntext|

%    the baseline (instead of superscripts) and followed by a dot
%    and an half quad space.  Whenever symbols are used to number
%    footnotes (as in |\thanks| for instance), we switch back to the

%  \subsection{Global layout}
%  \label{sec-global}
%
%    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 footnotes
%    (see~\ref{sec-footnotes}), and the indentation of the first
%    paragraph of sections (see~\ref{sec-indent}).
%
%    From version 2.2 on, if |frenchb| is \babel's ``main language''
%    (i.e.\ last language option at \babel's loading), |frenchb|
%    customises the layout (i.e.\ lists, indentation of the first
%    paragraphs of sections and footnotes) in the whole document
%    regardless the current language.  On the other hand, if |frenchb|
%    is \emph{not} \babel's ``main language'', it leaves the layout
%    unchanged both in French and in other languages.

%    Inputing French quotes as \emph{single characters} when they are
%    available on the keyboard (through a compose key for instance)
%    is more comfortable than typing |\og| and |\fg|.
%    The purpose of the following code is to map the French quote
%    characters to |\og\ignorespaces| and |{\fg}| respectively when
%    the current language is French, and to |\guillemotleft| and
%    |\guillemotright| otherwise (think of German quotes); thus correct
%    unbreakable spaces will be added automatically to French quotes.
%    The quote characters typed in depend on the input encoding,
%    it can be single-byte (latin1, latin9, applemac,\dots) or
%    multi-bytes (utf-8, utf8x).  We first check whether XeTeX or
%    LuaTeX engines are used, if not the \file{inputenc} package has to
%    be loaded before the |\begin{document}| with the proper coding
%    option, so we check if |\DeclareInputText| is defined.
%

%   `og' and `fg' options now set XeTeXcharclasses of these characters

%    It is time to process the options set with |\frenchboptions{}|.
%    Then we need to execute either |\extrasfrench| and
%    |\captionsfrench| or |\noextrasfrench| according to the current
%    language at the |\begin{document}| (these three commands have been
%    updated by |\FBprocess@options|).  \emph{But}, when French is the
%    main language, |\extrasfrench| is executed \emph{again} now
%    (French has been switched on `AtBeginDocument' some time before).
%    This is harmless, except for |\bbl@frenchspacing| which will
%    redefine |\bbl@nonfrenchspacing| to |\relax|, this will be
%    wrong if the user switches to English.
%    When French is \emph{not} the main language, |\noextrasfrench|
%    executes |\bbl@nonfrenchspacing| (=|\nonfrenchspacing|), thus
%    eventually overwriting a |\frenchspacing| command issued by the
%    main language (German, Spanish, etc.).
%    So we have to define |\bbl@nonfrenchspacing| as |\relax| here
%    and restore it's meaning afterwards.
%
%    It is also the right time, when a koma-script class is in use, to
%    save the value of |\captionformat| in |\CaptionSeparatorORI}| and
%    to add the redefinitions of |\captionformat| to
