%%% This is language.dat as of September 2006 at (your site)
%%%
%%% This file: is coming from FrenchPro <http://www.frenchpro6.com/french.html>
%%%            is to be used with hycongig.tex version not less than V2.0;
%%%            is babel compatible (since V3.6 of Babel).
%%%            is MikTeX compatible (since MikTeX 2.5)
%%%
%%% This file tells TeX which are the languages and dialects, 
%%%                     which are the hyphenation files (patterns),
%%%                     which are the hyphenation exception files,
%%%                 and which encoding is to be used for other hyphenation char.
%%%                     (For syntax look at the bottom.)
%%%
%%% CHECK IF THIS IS THE ONLY language.dat FILE OF YOUR SYSTEM, otherwise
%%% remove (or rename) all unused, and keep just (this) one.

%%%============================================================================%
%%% Each of the three parts (language_name, patterns_file and exceptions_file)
%%% must be separated by a blank space. You can omit any of the file names if 
%%% your language has not this component.
%%%
%%% First language will have language number 0 when used by hyconfig.tex
%%% at an INITeX time or used by french.sty version > 3.
%%%                      (once INITeX is done don't change the language order!)
%%%
%%% An "=" in front of the language name means that this language must use the
%%% same language number that the previous language (and the same patterns or
%%% exceptions files). So you can use the equal sign to define dialects.
%%% If this is the first language then the next language will be numbered 0 too;
%%% the language name is the only thing used here; patterns, exceptions file
%%% and encoding are never taken in account in this special dialect case.
%%%
%%% Font encoding (last field) is defaultly "t1". That field gives you the
%%% possibility to use the appropriate hyphen char when you switch to that
%%% font encoding. If you don't want default value then set it to "-".
%%%
%%% Any missing field can be replaced by a "-" (except language name and 
%%%                                             patterns file)
%%%
%%% At INITeX time, the basic files to congigurate are:
%%% - language.dat, (that file you are reading!),
%%% - plain.tex for plain TeX format, which calls "\input hyphen".
%%%   In order to use "language.dat" for language definition you have to replace
%%%   "\input hyphen" by "\input hyphen.cfg". Then do as for LaTeX:
%%% - hyphen.cfg for LaTeX format which will load the master hyphenation code 
%%%   hyconfig.tex that does the job of loading the appropriate files. 
%%%
%%% Notice that "enhyph.tex" and "enhyphex.tex" are often derivates of the
%%% original "hyphen.tex" (in fact only a split between patterns and exceptions)
%%% But you must know that english (ie british) patterns exist. See archives. 
%%%
%%% Notice also that few TeX engines may require non-empty hyphenation
%%% "exceptions file" fields. In such cases provide null.tex.
