% macro's for the Basque language.
%
% For this language the characters |~| and |"| are made
% active. In table~\ref{tab:basque-quote} an overview is given of
% their 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 the old |\-|, but allowing hyphenation
% in the rest of the word. \\
% |"<| & for French left double quotes (similar to $<<$).\\
% |">| & for French right double quotes (similar to $>>$).\\
% |~n| & a n with tilde. Works for uppercase too.

% This option includes support for working with extended, 8-bit
% fonts, if available. Support is based on
% providing an appropriate definition for the accent macros on
% entry to the Basque language. This is automatically done by
% \LaTeXe\ or NFSS2. If T1 encoding is chosen, and provided that
% adequate hyphenation patterns\footnote{One source for such
% patterns is the archive at \texttt{tp.lc.ehu.es} that can be
% accessed by anonymous FTP or in
% \texttt{
http://tp.lc.ehu.es/jma/basque.html}} are available.
% The easiest way to use the new encoding with \LaTeXe{} is
% to load the package \texttt{t1enc} with |\usepackage|. This must
% be done before loading \babel.
%
% \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.

% \end{macrocode}
%
% When this file is read as an option, i.e. by the |\usepackage|
% command, \texttt{basque} could be an `unknown' language in which
% case we have to make it known. So we check for the existence of
% |\l@basque| to see whether we have to do something here.

% characters are made active or are redefined. In particular, the

% meanings. Therefore these characters have to be treated as
% `special' characters.

% \begin{macro}{\dieresia}
% \begin{macro}{\texttilde}
% The original definition of |\"| is stored as |\dieresia|, because
% the we do not know what is its definition, since it depends on
% the encoding we are using or on special macros that the user
% might have loaded. The expansion of the macro might use the \TeX\
% |\accent| primitive using some particular accent that the font
% provides or might check if a combined accent exists in the font.
% These two cases happen with respectively OT1 and T1 encodings.
% For this reason we save the definition of |\"| and use that in
% the definition of other macros. We do likewise for |\'| and
% |\~|. The present coding of this option file is incorrect in that
% it can break when the encoding changes. We do not use
% |\tilde| as the macro name because it is already defined as
% |\mathaccent|.
% \begin{macrocode}

\let\texttilde\~

% \end{macro}
% \end{macro}
%
% \begin{macro}{\@umlaut}
% \begin{macro}{\@tilde}
% We check the encoding and if not using T1, we make the accents
% expand but enabling hyphenation beyond the accent. If this is the
% case, not all break positions will be found in words that contain
% accents, but this is a limitation in \TeX. An unsolved problem
% here is that the encoding can change at any time. The definitions
% below are made in such a way that a change between two 256-char
% encodings are supported, but changes between a 128-char and a
% 256-char encoding are not properly supported. We check if T1 is
% in use. If not, we will give a warning and proceed redefining the
% accent macros so that \TeX{} at least finds the breaks that are
% not too close to the accent. The warning will only be printed to
% the log file.
