Sadly, neither CTAN nor I can find any license information about the hrhyph.tex file, with Croatian hyphenation patterns. [email protected] bounces and I can find no alternate email address for the author, Marinovi\'c Igor.
So, unless one of you has better luck in searching, I see no alternative to removing hrhyph-derived files from hyph-utf8. Will there be an update of hyph-utf8 for TL'11? Thanks, k
