+% This macro is called from txi-??.tex files; the first argument is the

+% third args are \{left,right}hyphenmin.

+% The language names to pass are determined when the format is built.
+% See the etex.log file created at that time, e.g.,
+% /usr/local/texlive/2008/texmf-var/web2c/pdftex/etex.log.
+%
+% With TeX Live 2008, etex now includes hyphenation patterns for all
+% available languages. This means we can support hyphenation in
+% Texinfo, at least to some extent. (This still doesn't solve the
