% This file contains additional hyphenation patterns including
% the character hyphen `-' to be used in conjunction with
%
% * all fonts with font encoding T1 and
% * all national hyphenation patterns.
%
% It enables the hyphenation of words containing explicit hyphens
% when using fonts with \hyphenchar\font <> `\- (e.g. EC fonts).
%
% It is an experimental version for testing and includes all
% lowercase characters (including national characters) in T1
% encoded fonts.
% In 1990 at the TUG meeting at Cork, Ireland, the european TeX
% user groups agreed on a 256 character encoding supporting many
% european languages with latin writing. LaTeX2e supports this
% character encoding as font encoding "T1".
%
%
% The additional patterns add about 2600 patterns and 6 trie ops.
% Be warned---to load the patterns in the IniTeX pass when creating
% a new format a very large hyphenation trie is needed!
% Example: TeX reports for "hyphen.tex"
% Hyphenation trie of length 6075 has 181 ops out of ...
% with the additional patterns it will report
% Hyphenation trie of length 8618 has 187 ops out of ...
%
%
% Note:
% The \hyphenation command gives special interpretation to the
% character `-'. Therefore it is not possible to include a
% word with an explicit hyphen as hyphenation exception without
% the following trick (from David Kastrup):
%
% \begingroup
% % Make `=' to be seen as an explicit hyphen inside \hyphenation:
% \lccode`\==`\-
% % Example: Declare hyphenation points of `government-founded':
% \hyphenation{gov-ern-ment=-foun-ded}

%
% Installation:
% =============
%
% 1. Make sure that the hyphenation trie of your TeX version has
% enough room to load more hyphenation patterns (cf. "pattern
% memory", "trie size" in the documentation of your
% implementation).
%
% 2. load "hypht1.tex" in addition to _every_ hyphenation
% patterns file (i.e. for every value of \language) you are
% using; make sure that \language has not been changed.
%
% Example for LaTeX2e (without Babel's ``language.dat''):
% To load US English and German hyphenation patterns, and load
% "hypht1.tex" in addition to both sets of patterns, create a
% file "hyphen.cfg" with the following contents:
%
% \chardef\l@USenglish=0 \language=\l@USenglish
% \input hyphen
% \input hypht1
%
% \newlanguage\l@german \language=\l@german
% \input dehypht
% \input hypht1
%
% \language=\l@USenglish
% \lefthyphenmin=2 \righthyphenmin=3
% \endinput
%
% Example for LaTeX2e (using Babel's ``language.dat''):
% To load a second file including additional hyphenation patterns
% and hyphenation exceptions you specify the name of the file
% in ``language.dat'' in addition to the regular hyphenation
% pattern file name. For example
% USenglish hyphen.tex hypht1.tex
% german dehypht.tex hypht1.tex
%
%
% 3. Use IniTeX to create a new format file.

% 2000-01-31 v0.3 added missing glyphs '340-'377

%
% It is possible to use T1-encoded font with TeX 2.x and
% include a subset '000-'177 of these additional hyphenation
% patterns. Nonetheless TeX 2.x is unable to process more than
% one \patterns. If you want to use these patterns, you have to
% include some changes below and in the used set of patterns.
