%  \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. This file was initially derived from the original
%    version of \file{german.sty}, which has some definitions for
%    French. Later the definitions from \file{french.sty} version 2
%    were added.} defines all the language-specific macros for the
%    French language.
%
%    French typographic rules specify that a little white space should
%    be added before `double puctuation' characters. These characters
%    are {\tt :}, {\tt ;}, {\tt !} and {\tt ?}. In order to get this
%    whitespace automatigically the category code of these characters
%    is made |\active|.
%
% \StopEventually{}
%
%    As this file needs to be read only once, we check whether it was
%    read before. If it was, the |\captionsfrancais| is already
%    defined, so we can stop processing. If this command is undefined
%    we proceed with the various definitions and first show the
%    current version of this file.
%
% \changes{french-4.2a}{15 july 91}{Added reset of catcode of @ before

%
% \changes{french-4.2e}{29 okt 91}{Removed code to load {\tt latexhax.com}}
%
% \begin{macro}{\atcatcode}
%    This file, \file{francais.sty}, may have been read while \TeX\ is
%    in the middle of processing a document, so we have to make sure
%    the category code of {\tt @} is `letter' while this file is being
%    read. We save the category code of the @-sign in
%    |\atcatcode| and make it `letter'. Later the category code
%    can be restored to whatever it was before.
% \changes{french-4.1a}{6 june 91}{Made test of catcode of @ more
%                                  robust}

%    \end{macrocode}
% \end{macro}
%
%    Now we determine whether the the common macros from the file
%    \file{babel.def} need to be read. We can be in one of two
%    situations: either another language option has been read earlier
%    on, in which case that other option has already read
%    \file{babel.def}, or {\tt francais} is the first language option
%    to be processed. In that case we need to read \file{babel.def}
%    right here before we continue.
% \changes{french-3.0}{23 april 1991}{New check before loading

%                                {\tt\bsl originalTeX}}
%    Another check that has to be made, is if another language specific
%    file has been read already. In that case its definitions have
%    been activated. This might interfere with definitions this file
%    tries to make. Therefore we make sure that we cancel any
%    special definitions. This can be done by checking the existence
%    of the macro |\originalTeX|. If it exists we simply execute it,
%    otherwise it is |\let| to |\empty|.
% \changes{french-4.2a}{15 july 91}{Added {\tt\bsl let\bsl

%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, {\tt francais} will be an `unknown' language in which
%    case we have to make it known.  So we check for the existence of
%    |\l@francais| to see whether we have to do something here.
%
% \changes{french-3.0}{23 april 91}{Now use {\tt\bsl adddialect} if

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

%    |\noextrasfrancais| is used to cancel the actions of
%    |\extrasfrancais|.
%
%    The category code of the characters {\tt :}, {\tt ;}, {\tt !} and

%    Therefore they have to be treated as `special' characters.
