%  \section{The Catalan 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-specific macro's for the
%    Catalan language.
%
%    For this language only the double quote character (|"|) is made
%    active by default. In table~\ref{tab:catalan-quote-def} an
%    overview is given of the new macros defined and the new meanings
%    of |"|. Additionally to that, the user can explicitly activate
%    the acute accent or apostrophe (|'|) and/or the grave accent
%    (|`|) characters by using the \Lopt{activeacute} and
%    \Lopt{activegrave} options. In that case, the definitions shown
%    in table~\ref{tab:catalan-quote-opt} also become
%    available\footnote{Please note that if the acute accent character
%    is active, it is necessary to take special care of coding
%    apostrophes in a way which cannot be confounded with
%    accents. Therefore, it is necessary to type \texttt{l'\{\}estri}
%    instead of \texttt{l'estri}.}.

%    be defined as |\accent"7F 1|, but as |\accent'310 #1|. Something
%    similar happens when using fonts that follow the Cork
%    encoding. For this reason we save the definition of |\"| and use

%    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

%    not too close to the accent. The warning will only be printed to

%    If the user setup has extended fonts, the Ferguson macros are
%    required to be defined. We check for their existance and, if
%    defined, expand to whatever they are defined to. For instance,
%    |\'a| would check for the existance of a |\@ac@a| macro. It is
%    assumed to expand to the code of the accented letter.  If it is
%    not defined, we assume that no extended codes are available and
%    expand to the original definition but enabling hyphenation beyond
%    the accent. This is as best as we can do. It is better if you
%    have extended fonts or ML-\TeX{} because the hyphenation
%    algorithm can work on the whole word. The following macros are
%    directly derived from ML-\TeX{}.\footnote{A problem is perceived
%    here with these macros when used in a multilingual environment
%    where extended hyphenation patterns are available for some but
%    not all languages. Assume that no extended patterns exist at some
%    site for French and that \file{french.sty} would adopt this
%    scheme too. In that case, \mbox{\texttt{'e}} in French would
%    produce the combined accented letter, but hyphenation around it
%    would be suppressed. Both language options would need an
%    independent method to know whether they have extended patterns
%    available. The precise impact of this problem and the possible
%    solutions are under study.}

%    All that is left now is the redefinition of |\-|. The new version

%    allowing other hyphenation positions to be generated
%    automatically. The standard behaviour of \TeX\ in this respect is
%    unfortunate for Catalan but not as much as for Dutch or German,
%    where long compound words are quite normal and all one needs is a
%    means to indicate an extra hyphenation position on top of the
%    ones that \TeX\ can generate from the hyphenation
%    patterns. However, the average length of words in Catalan makes
%    this desirable and so it is kept here.

%
%    Here we define a macro for typing the catalan ``ela geminada''
%    (geminated l). The macros |\lgem| and |\Lgem| have been chosen
%    for its lowercase and uppercase representation,
%    respectively\footnote{The macro names \cs{ll} and \cs{LL} were
%    not taken because of the fact that \cs{ll} is already used in
%    mathematical mode.}.
%
%    The code used in the actual macro used is a combination of the
%    one proposed by Feruglio and Fuster\footnote{G.~Valiente and
%    R.~Fuster, Typesetting Catalan Texts with \TeX, \emph{TUGboat}
%    \textbf{14}(3), 1993.} and the proposal\footnote{G. Valiente,
%    Modern Catalan Typographical Conventions, \emph{TUGboat}
%    \textbf{16}(3), 1995.} from Valiente presented at the \TeX\ Users
%    Group Annual Meeting in 1995. This last proposal has not been
%    fully implemented due to its limitation to CM fonts.
