%  \section{The Portuguese language}
%
%    The file \file{\filename}\footnote{The file described in this
%    section has version number \fileversion\ and was last revised on
%    \filedate.  Contributions were made by Jose Pedro Ramalhete
%    (\texttt{JRAMALHE@CERNVM} or
%    \texttt{Jose-Pedro\_Ramalhete@MACMAIL}) and Arnaldo Viegas de
%    Lima \texttt{arnaldo@VNET.IBM.COM}.}  defines all the
%    language-specific macros for the Portuguese language as well as
%    for the Brasilian version of this language.
%
%    For this language the character |"| is made active. In
%    table~\ref{tab:port-quote} an overview is given of its purpose.
%
%    \begin{table}[htb]
%     \centering
%     \begin{tabular}{lp{8cm}}
%       \verb="|= & disable ligature at this position.\\
%        |"-| & an explicit hyphen sign, allowing hyphenation
%               in the rest of the word.\\
%        |""| & like \verb="-=, but producing no hyphen sign (for
%              words that should break at some sign such as
%              ``entrada/salida.''\\
%        |"<| & for French left double quotes (similar to $<<$).\\
%        |">| & for French right double quotes (similar to $>>$).\\
%        |\-| & like the old |\-|, but allowing hyphenation
%               in the rest of the word. \\
%     \end{tabular}
%     \caption{The extra definitions made by \file{portuges.ldf}}
%     \label{tab:port-quote}
%    \end{table}
%
% \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{portuges-1.2j}{1996/11/03}{Now use \cs{LdfInit} to perform
%    initial checks} 
%    \begin{macrocode}
%<*code>
\LdfInit\CurrentOption{captions\CurrentOption}
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{portuges} will be an `unknown' language in which
%    case we have to make it known. So we check for the existence of
%    |\l@portuges| to see whether we have to do something here. Since
%    it is possible to load this file with any of the following four
%    options to babel: \Lopt{portuges}, \Lopt{portuguese},
%    \Lopt{brazil} and \Lopt{brazilian} we also allow that the
%    hyphenation patterns are loaded under any of these four names. We
%    just have to find out which one was used.
%
% \changes{portuges-1.0b}{1991/10/29}{Removed use of cs{@ifundefined}}
% \changes{portuges-1.1}{1992/02/16}{Added a warning when no
%    hyphenation patterns were loaded.}
% \changes{portuges-1.2d}{1994/06/26}{Now use \cs{@nopatterns} to
%    produce the warning}
%    \begin{macrocode}
\ifx\l@portuges\@undefined
  \ifx\l@portuguese\@undefined
    \ifx\l@brazil\@undefined
      \ifx\l@brazilian\@undefined
        \@nopatterns{Portuguese}
        \adddialect\l@portuges0
      \else
        \let\l@portuges\l@brazilian
      \fi
    \else
      \let\l@portuges\l@brazil
    \fi
  \else
    \let\l@portuges\l@portuguese
  \fi
\fi
%    \end{macrocode}
%    By now |\l@portuges| is defined. When the language definition
%    file was loaded under a different name we make sure that the
%    hyphenation patterns can be found.
%    \begin{macrocode}
\expandafter\ifx\csname l@\CurrentOption\endcsname\relax
  \expandafter\let\csname l@\CurrentOption\endcsname\l@portuges
\fi
%    \end{macrocode}
%
%    Now we have to decide whether this language definition file was
%    loaded for Portuguese or Brasilian use. This can be done by
%    checking the contents of |\CurrentOption|. When it doesn't
%    contain either `portuges' or `portuguese' we make |\bbl@tempb|
%    empty. 
%    \begin{macrocode}
\def\bbl@tempa{portuguese}
\ifx\CurrentOption\bbl@tempa
  \let\bbl@tempb\@empty
\else
  \def\bbl@tempa{portuges}
  \ifx\CurrentOption\bbl@tempa
    \let\bbl@tempb\@empty
  \else
    \def\bbl@tempb{brazil}
  \fi
\fi
\ifx\bbl@tempb\@empty
%    \end{macrocode}
%
%    The next step consists of defining commands to switch to (and from)
%    the Portuguese language.
%
% \begin{macro}{\captionsportuges}
%    The macro |\captionsportuges| defines all strings used
%    in the four standard documentclasses provided with \LaTeX.

%    Some discussion took place around the correct translations for
%    `Table of Contents' and `Index'. the translations differ for
%    Portuguese and Brasilian based the following history:
%    \begin{quote}
%      The whole issue is that some books without a real index at the
%      end misused the term `\'Indice' as table of contents. Then,
%      what happens is that some books apeared with `\'Indice' at the
%      begining and a `\'Indice Remissivo' at the end. Remissivo is a
%      redundant word in this case, but was introduced to make up the
%      difference. So in Brasil people started using `Sum\'ario' and
%      `\'Indice Remissivo'. In Portugal this seems not to be very
%      common, therefore we chose `\'Indice' instead of `\'Indice
%      Remissivo'.
