102 % macro's for the Basque language.
103 %
104 % For this language the characters |~| and |"| are made
105 % active. In table~\ref{tab:basque-quote} an overview is given of
106 % their purpose.
107 % \begin{table}[htb]

110 % \verb="|= & disable ligature at this position.\\
111 % |"-| & an explicit hyphen sign, allowing hyphenation
112 % in the rest of the word.\\
113 % |\-| & like the old |\-|, but allowing hyphenation
114 % in the rest of the word. \\
115 % |"<| & for French left double quotes (similar to $<<$).\\
116 % |">| & for French right double quotes (similar to $>>$).\\
117 % |~n| & a n with tilde. Works for uppercase too.

119 % \caption{The extra definitions made by \file{basque.ldf}}

122 % These active accent characters behave according to their original
123 % definitions if not followed by one of the characters indicated in
124 % that table.

128 % This option includes support for working with extended, 8-bit
129 % fonts, if available. Support is based on
130 % providing an appropriate definition for the accent macros on
131 % entry to the Basque language. This is automatically done by
132 % \LaTeXe\ or NFSS2. If T1 encoding is chosen, and provided that
133 % adequate hyphenation patterns\footnote{One source for such
134 % patterns is the archive at \texttt{tp.lc.ehu.es} that can be
135 % accessed by anonymous FTP or in
136 % \texttt{http://tp.lc.ehu.es/jma/basque.html}} are available.
137 % The easiest way to use the new encoding with \LaTeXe{} is
138 % to load the package \texttt{t1enc} with |\usepackage|. This must
139 % be done before loading \babel.

143 % The macro |\LdfInit| takes care of preventing that this file is

151 % When this file is read as an option, i.e. by the |\usepackage|
152 % command, \texttt{basque} could be an `unknown' language in which
153 % case we have to make it known. So we check for the existence of

266 % The original definition of |\"| is stored as |\dieresia|, because
267 % the we do not know what is its definition, since it depends on
268 % the encoding we are using or on special macros that the user
269 % might have loaded. The expansion of the macro might use the \TeX\
270 % |\accent| primitive using some particular accent that the font
271 % provides or might check if a combined accent exists in the font.
272 % These two cases happen with respectively OT1 and T1 encodings.
273 % For this reason we save the definition of |\"| and use that in
274 % the definition of other macros. We do likewise for |\'| and
275 % |\~|. The present coding of this option file is incorrect in that
276 % it can break when the encoding changes. We do not use
277 % |\tilde| as the macro name because it is already defined as

292 % here is that the encoding can change at any time. The definitions
293 % below are made in such a way that a change between two 256-char
294 % encodings are supported, but changes between a 128-char and a
295 % 256-char encoding are not properly supported. We check if T1 is
296 % in use. If not, we will give a warning and proceed redefining the
297 % accent macros so that \TeX{} at least finds the breaks that are
298 % not too close to the accent. The warning will only be printed to
