% \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 and Australian
% version of this language. For the Australian version the British
% hyphenation patterns will be used, if available, for the Canadian
% variant the American patterns are selected.
%
% 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.

% initial checks}

%
% 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.
