+%  \subsubsection*{What’s new in version 3.4?}
+%
+%    Version 3.4a adds a new command |\frenchdate| (see
+%    p.~\pageref{sssec-date}) and slightly changes number formatting:
+%    |\FBthousandsep| is now a \textit{kern} instead of a rubber
+%    length.  |\renewcommand*{\FBthousandsep}{~}| will switch back
+%    to the former (wrong) behaviour.
+%
+%    Both options \Lopt{french} and \Lopt{acadian} can now be used
+%    simultaneously in a document; currently \Lopt{french} and
+%    \Lopt{acadian} are identical, it is up to the user to customise
+%    \Lopt{acadian} in terms of hyphenation patterns, captionnames,
+%    date format or high punctuation and quotes spacing if he/she
+%    needs a variant for French.
+%
+%    A new command |\FBsetspaces| has been added for easy customising of
+%    spacing before high punctuation and inside quotes independently for
+%    \Lopt{french} and \Lopt{acadian}, see p.~\pageref{FBsetspaces}.

+%  \begin{macro}{\FBsetspaces}
+%    This command makes it easy to fine tune |\FBguillspace|,
+%    |\FBcolonspace| and |\FBthinspace| in French (defaut) or
+%    independently in a French dialect using the optional argument.
+%    They are meant for \LaTeXe{} \emph{only} and can only be used
+%    in the preamble.
+%    Four mandatory arguments are expected besides the optional one:
+%    the first one is a \textit{string} either "guill", "colon", or
+%    "thin", the last four are decimal numbers specifying
+%    \textit{width}, \textit{stretch} and \textit{shrink} relative to
+%    \textit{fontdimens}.\hlabel{FBsetspaces}
+%    For instance |\FBsetspaces[acadian]{colon}{0.5}{0}{0}| defines
+%    |\acadianFBcolonspace| as a thinspace which will be used for
+%    the Acadian dialect only.  When used without optional argument or
+%    with argument `french’, the same command would tune the basic
+%    |\FBcolonspace| command.

+%    Remember that the \emph{same} |\extrasfrench| command is executed
+%    when switching to French or to a French dialect (Acadian).
+%    Acadian and French may share the same patterns (or not), and may
+%    use different spacing for high punctuation and/or quotes.
+%    Basically, for pdfLaTeX and XeLaTeX, the spacing is set for French,
+%    then potentially tuned differently for Acadian.
+%    LuaTeX relies on an attribute |\FB@dialect| to decide what spacing
+%    is needed for French or Acadian (see LuaTeX table |FBsp|).
+%    \hlabel{extrapunct}
+%    As a rough test on |\languagename| would be unreliable to set the
+%    value of |\FB@dialect| (see \file{babel.pdf}), we use a trick
+%    based on |\detokenize|; another option would be to use the
