+%  \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.
+% \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}}

+%    UK patterns}
+% \changes{english-3.3j}{2000/01/21}{Also allow american english
+%    hyphenation patterns to be used for `english'}
+%    We allow for the british english patterns to be loaded as either
+%    `british', or `UKenglish'. When neither of those is
+%    known we try to define |\l@english| as an alias for |\l@american|
+%    or |\l@USenglish|.
+% \changes{english-3.3k}{2001/02/07}{Added support for canadian}
+% \changes{english-3.3n}{2004/06/12}{Added support for australian and

+%    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| was defined.
+%    Now we want to make sure that |\l@british| and |\l@UKenglish| are
+%    defined as well. When either of them is we make them equal to
+%    each other, when neither is we fall back to the default,
+%    |\l@english|.

+%    `American' is a version of `English' which can have its own

+%    for american english. We allow for the patterns to be loaded as

+%    `Canadian' english spelling is a hybrid of British and American
