%%% This is the file hyphen.smp which illustrates a way to set up
%%% hyphenation patterns for several languages.
%%% Copyright 2007 TeX Users Group.
%%% You may freely use, modify and/or distribute this file.

%%% With LaTeX 2e you may want to use the babel package, which provides
%%% extensive support for multi-lingual work.

%%% NOTE: You may want to first rename the original hyphen.tex file to
%%% ushyph.tex, then you can then rename this file hyphen.tex and run
%%% ini-TeX as you would when using just English.  The alternative is 
%%% to hunt down the place where hyphen.tex is \input and to instead 
%%% \input this hyphen.smp file.

%%% The hyphenation pattern files referenced here may be found 
%%% on the Y&Y TeX CD-ROM under CTAN/languages/hyphenation,
%%% or on CTAN itself under /tex-archive/languages/hyphenation.

%%% Note that there may be more than one hyphenation pattern file
%%% for a given language. These may differ in encoding assumptions e.g.
%%% Read the head of the hyphenation pattern files to decide which to use.

%%% Note that some old pattern files are set up for OT1 encoding.
%%% These do not permit proper hyphenation with accented characters.
%%% Others are set up for T1 encoding.  These can be used with LY1 also.

%%% You should be aware that hyphenation pattern files for T1 encoding
%%% differ in how they deal with `8-bit' characters.  
%%% Some   (i) use TeX control sequences (like \ss);
%%% others (ii) use TeX's ^^ hexadecimal notation (like ^^AE); while
%%% a few  (iii) use the `8-bit' characters directly.
%%% Of these, (i) is best and (iii) is the worst way of doing things.

%%% You wouldn't typically load up patterns for as many languages.
%%% This is just for illustration. Delete the ones you don't need.

%%% If you do use this many hyphenation patterns you will probably need 
%%% to expand hyphenation pattern memory from the command line in ini-TeX
%%% using -h, e.g.
%%%
%%%			tex -h=50000 plain.tex
%%%
%%% If you also have very many hyphenation exceptions, use -e.
%%% Type tex -? to get a full command line summary from yandytex.exe

%%% When switching languages you may also need to adjust \lefthyphenmin 
%%% and \righthyphenmin and possibly make some characters active or 
%%% change the catcode of some special characters.  See the hyphenation
%%% pattern files themselves for details.
