13 Text::Tradition::Language::French - language-specific module for French
17 Implements morphology lookup for French words in context. This module
18 depends on the Flemm module for French lemmatization
19 (L<http://www.univ-nancy2.fr/pers/namer/Outils.htm#fl3> in conjunction with
20 the TreeTagger software
21 (L<http://www.ims.uni-stuttgart.de/projekte/corplex/TreeTagger/>), which is
22 (for now) expected to be installed in $MORPHDIR/TreeTagger.
