-% ==========================================
-%
-% ushyphmax.tex -- patterns for more hyphenation pattern memory (12000+).
-% Also known as ushyphen.max.
-%
-% Needs extended pattern memory.
-% Hyphenation trie becomes 7283 with 377 ops.
-%
-% These patterns are based on the Hyphenation Exception Log
-% published in TUGboat, Volume 10 (1989), No. 3, pp. 337-341,
-% and a large number of incorrectly hyphenated words not yet published.
-% If added to Liang's before the closing bracket } of \patterns,
-% the patterns run errorfree as far as known at this moment.
-%
-% These patterns find all admissible hyphens of the words in
-% the Exception Log.  ushyph2.tex is a smaller set.
-%
-% Please send bugs or suggestions to tex-live (at) tug.org.
-%
-% 2005-05-30 (karl): in the past, ushyphmax.tex was a file containing
-% only the additional patterns, without the \patterns command, etc.
-% This turned out not to be very useful, since in practice the TeX
-% distributions need one self-contained file for a language.  Therefore,
-% ushyphmax.tex now contains both the additional patterns from
-% Dr. Kuiken, and the original patterns and hyphenations from Knuth's
-% hyphen.tex.
-%
-% The Plain TeX hyphenation tables.
