%  \section{The Swedish 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 Sten Hellman
%    (\texttt{HELLMAN@CERNVM.CERN.CH}) and Erik \"Osthols
%    (\texttt{erik\_osthols@yahoo.com}).} defines all the
%    language-specific macros for the Swedish language. This
%    file has borrowed heavily from |finnish.dtx| and |germanb.dtx|.
%
%    For this language the character |"| is made active. In
%    table~\ref{tab:swedish-quote} an overview is given of its
%    purpose. The vertical placement of the "umlaut" in some letters
%    can be controlled this way.
%    \begin{table}[htb]
%     \begin{center}
%     \begin{tabular}{lp{8cm}}
%      |"a| & Gives \"a, also implemented for |"A|, |"o| and |"O|. \\
%      |"w|, |"W| & gives {\aa} and {\AA}.                         \\
%      |"ff| & for |ff| to be hyphenated as |ff-f|. Used for compound
%              words, such as \texttt{stra|"|ff{\aa}nge}, which
%              should be hyphenated as \texttt{straff-f{\aa}nge}.
%              This is also implemented for b, d, f, g, l, m, n,
%              p, r, s, and t.                                     \\
%      \verb="|= & disable ligature at this position. This should be 
%              used for compound words, such as
%              ``\texttt{stra|"|ffinr\"attning}'',
%              which should not have the ligature ``ffi''.         \\
%      |"-| & an explicit hyphen sign, allowing hyphenation
%             in the rest of the word, such as e. g. in
%             ``x|"-|axeln''.                                      \\
%      |""| & like |"-|, but producing no hyphen sign
%             (for words that should break at some sign such as
%             \texttt{och/|""|eller}).                             \\
%      |"~| & for an explicit hyphen without a breakpoint; useful for
%             expressions such as ``2|"~|3 veckor'' where no linebreak
%             is desirable.                                        \\
%      |"=| & an explicit hyphen sign allowing subsequent hyphenation,
%             for expressions such as ``studiebidrag och \newline
%             -l{\aa}n''.                                          \\
%      |\-| & like the old |\-|, but allowing hyphenation
%             in the rest of the word.                             \\
%     \end{tabular}
%     \caption{The extra definitions made
%              by \file{swedish.sty}}\label{tab:swedish-quote}
%     \end{center}
%    \end{table}
%
%    Two variations for formatting of dates are added. \cs{datesymd}
%    makes \cs{today} output dates formatted as YYYY-MM-DD, which is
%    commonly used in Sweden today. \cs{datesdmy} formats the date as
%    D/M YYYY, which is also very common in Sweden. These commands
%    should be issued after \cs{begin{document}}.
%
% \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{swedish-2.1}{1996/11/03}{Now use \cs{LdfInit} to perform
%    initial checks} 
%    \begin{macrocode}
%<*code>
\LdfInit{swedish}\captionsswedish
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{swedish} will be an `unknown' language in which
%    case we have to make it known. So we check for the existence of
%    |\l@swedish| to see whether we have to do something here.
%
% \changes{swedish-1.0c}{1991/10/29}{Removed use of \cs{@ifundefined}}
% \changes{swedish-1.1}{1992/02/16}{Added a warning when no hyphenation
%    patterns were loaded.}
% \changes{swedish-1.3d}{1994/06/26}{Now use \cs{@nopatterns} to

%    \begin{macrocode}
\ifx\l@swedish\@undefined
    \@nopatterns{Swedish}
    \adddialect\l@swedish0\fi
%    \end{macrocode}
%
%    The next step consists of defining commands to switch to the
%    Swedish language. The reason for this is that a user might want
%    to switch back and forth between languages.
%
% \begin{macro}{\captionsswedish}

%    The ``umlaut'' accent macro |\"| is changed to lower the

%    |\umlautlow|.
%^^A    PROBLEM:
%^^A    What happens to ``umlaut''

%
%    The code above is necessary because we need an extra active
%    character. This character is then used as indicated in
%    table~\ref{tab:swedish-quote}.
%
%    To be able to define the function of |"|, we first define a
%    couple of `support' macros.
%
%  \begin{macro}{\dq}
%    We save the original double quote character in |\dq| to keep
%    it available, the math accent |\"| can now be typed as |"|.
