+% $Id$
+% language.us (and the start of language.dat)
+% - initial hyphenation patterns.
+% Created long ago by Sebastian Rahtz and others.  Public domain.
+%
+% DO NOT EDIT THIS FILE (language.dat)! It is generated by tlmgr.
+%
+% The premade texmf/tex/generic/config/language.dat* files (where you
+% might be reading this) in the distribution was generated with all
+% languages enabled.  It is used when running live.
+%
+% To enable or disable languages, there are two options:
+% - if the language is provided by a TeX Live package, you can
+%   (un)install the corresponding package using tlmgr. Examples:
+%     tlmgr install hyphen-french
+%     tlmgr remove hyphen-english
+% - in any case, you can use local configuration files:
+%     TEXMFLOCAL/tex/generic/config/language-local.dat
+%     TEXMFLOCAL/tex/generic/config/language-local.dat.lua
+%     TEXMFLOCAL/tex/generic/config/language-local.def
+%   See the tlmgr documentation (try `man tlmgr' or `texdoc tlmgr'),
+%   section "generate" for details.
+%
+% The preferred comment for actual language lines in language.dat and
+% language.us is %!. Do not use %!  for textual comments like this. This
+% is to be able to separate textual comments from commented-out language
+% in such a way that automatic parsing by programs is possible, so that
+% we can present the user with `all possible languages'.
+% 
+% We must keep english as the default (first) here, and let it refer to
+% hyphen.tex (not anything else), and do not change the hyphen.tex file,
+% or name some other file hyphen.tex.  In other words, hyphen.tex must
+% remain the original file from Knuth, and it must be \language0.  This
+% is one important aspect of ensuring that the original, frozen TeX
+% always produces the same line and page breaks.
+% 
+% The babel system allows you to easily change the active language for
+% LaTeX. For more information, see the documentation in
+% texmf-dist/doc/generic/babel/.  ConTeXt has its own language support too.

+%
+% ushyphmax.tex, on the other hand, includes Gerard Kuiken's additional
+% patterns; it is not frozen.  It is provided by the hyphen-english
+% package, not listed here.  Also, in hyph-utf8 and current TL, it has
+% been renamed to hyph-en-us.tex, along with other *hyph-en-us.* files.
+%
+% FYI, ushyph.tex is Dr. Kuiken's smaller set of patterns; with today's
+% large memories, there is no reason to use it, and we don't list it here.
+% ushyph1.tex is another (historical) name for hyphen.tex.
+% ushyph2.tex is another (historical) name for ushyph.tex.
