1. - French hyphenation dictionary
Here is the download link for the main dictionary.
http://www.dicollecte.org/download.php?prj=fr
On this page, you can download (flagged with a green star) "
Césures 3.0." which will provide you with the "
hyph-fr-v3.0" folder. Within the file "
README_hyph_fr.txt" are the mail coordinates of the authors of the three successives versions.
This hyphenation dictionary works with a software named "
hyphen" which is part of the Hunspell project. It has been converted from a dictionary for Latex and further improved by several persons. I have no other information.
