%  \section{The English 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
%    English language as well as for the American version of this
%    language.
%
%    For this language currently no special definitions are needed or
%    available.
%
% \StopEventually{}
%
%    The macro |\LdfInit| takes care of preventing that this file is
%    loaded more than once, checking the category code of the
%    \texttt{@} sign, etc.
% \changes{english-3.3h}{1996/11/02}{Now use \cs{LdfInit} to perform
%    initial checks} 
%    \begin{macrocode}
%<*code>
\LdfInit\CurrentOption{date\CurrentOption}
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{english} could be an `unknown' language in which
%    case we have to make it known.  So we check for the existence of
%    |\l@english| to see whether we have to do something here.
%
% \changes{english-3.0}{1991/04/23}{Now use \cs{adddialect} if
%    language undefined}
% \changes{english-3.0d}{1991/10/22}{removed use of \cs{@ifundefined}}
% \changes{english-3.3c}{1994/06/26}{Now use \cs{@nopatterns} to
%    produce the warning}
% \changes{english-3.3g}{1996/07/10}{Allow british as the name of the
%    UK patterns} 
%    We allow for the british english patterns to be loaded as either
%    `english', `british', or `UKenglish'
%    \begin{macrocode}
\ifx\l@english\@undefined
  \ifx\l@UKenglish\@undefined
    \ifx\l@british\@undefined
      \@nopatterns{English}
      \adddialect\l@english0
    \else
      \let\l@english\l@british
    \fi 
  \else
    \let\l@english\l@UKenglish
  \fi
\fi
%    \end{macrocode}
%    Because we allow `british' to be used as the babel option we need
%    to make sure that it will be recognised by |\selectlanguage|. In
%    the code above we have made sure that |\l@english| has a sensible
%    value; now we make |\l@british| equal to that.
%    \begin{macrocode}
\ifx\l@british\@undefined
  \let\l@british\l@english
\fi
%    \end{macrocode}
%    `American' is a version of `English' which can have its own
%    hyphenation patterns. The default english patterns are in fact
%    for american english. We allow for the patterns to be loaded as
%    `english' `american' or `USenglish'.
% \changes{english-3.0}{1990/04/23}{Now use \cs{adddialect} for
%    american}
% \changes{english-3.0b}{1991/06/06}{Removed \cs{global} definitions}
% \changes{english-3.3d}{1995/02/01}{Only define american as a
%    dialect when no separate patterns have been loaded}
% \changes{english-3.3g}{1996/07/10}{Allow USenglish as the name of
%    the american patterns} 
%    \begin{macrocode}
\ifx\l@american\@undefined
  \ifx\l@USenglish\@undefined
%    \end{macrocode}
%    When the patterns are not know as `american' or `USenglish' we
%    add a ``dialect''.
%    \begin{macrocode}
    \adddialect\l@american\l@english
  \else
    \let\l@american\l@USenglish
  \fi
\fi
%    \end{macrocode}
%
%    The next step consists of defining commands to switch to (and
%    from) the English language.
