#    This script generates TeX hyphenation patterns for Basque
#    and was written by (c) Juan M. Aguirregabiria, 1997
#    based on the shyphen.sh file by Julio Sanchez, which
#    generates the hyphenation patterns for Spanish
#    The copyright notice below applies to this script as well,
#    read it before using this software.
#
# Usage: script [TeX] [ftc] [isolatin1]
#
#       TeX     \~n and \~N are done as in plain TeX and LaTeX
#               but without the escape character: ~n, ~N
#       ftc     these characters are specified using the
#               ftc conventions: 'n, 'N
#       isolatin1 means using the respective character codes in
#               IS 8859/1 (ISO Latin Alphabet 1)
#
# Default is no support for diacritics. You can use combinations
# of the above and the number of patterns will grow fast.
#
# Recommended options:
#
# isolatin1     if you have TeX 3.0 with DC/EC fonts or ML-TeX
# TeX           if you don't have the above
# ftc           if you are used to ftc and don't have the above
#
# h is not here.

% Hyphenation patterns for Basque.
% This file has been written by Juan M. Aguirregabiria
% ([email protected]) on February 1997 and is based
% on the shyphen.sh script that generates the Spanish patterns
% as compiled by Julio Sanchez ([email protected]) on September 1991.

%
% Hyphenation patterns for Spanish.
% Compiled by Julio Sanchez ([email protected]) on September 1991.
% These patterns have been derived from \"On Word Division in Spanish\",
% Jos'e A. Ma~nas, Communications of the ACM, and implemented in his
% package ftc. You can get ftc and a draft of the abovementioned
% paper from goya.dit.upm.es in src/text.proc/ftc.Z. FTP access may
% be available. Otherwise, send help to [email protected] for
% details on use of the mail server.
%
% Rules mentioned below are those described in that paper. After
% several unsatisfactory attempts to pretend I knew better, these
% patterns closely follow that paper. Pattern 'tl' is not considered.
% It is conflictive and ftc does not use it either.
%
% These patterns have been generated by shyphen.sh version $version,
% shyphen.sh is a sh script that allows a number of choices.
% Full benefit from some of these options can only be
% obtained if appropriate fonts are available.

% Follows a copyright notice. This is not in the public domain,
% but the copyright is essentially a hold-harmless clause. That
% is, use it at will, but don't sue me if you don't like it.
