=head1 NAME
-Text::Tradition::Language::French - language-specific modules for French
+Text::Tradition::Language::French - language-specific module for French
=head1 DESCRIPTION
-Implements morphology lookup for French words in context.
+Implements morphology lookup for French words in context. This module
+depends on the Flemm module for French lemmatization
+(L<http://www.univ-nancy2.fr/pers/namer/Outils.htm#fl3> in conjunction with
+the TreeTagger software
+(L<http://www.ims.uni-stuttgart.de/projekte/corplex/TreeTagger/>), which is
+(for now) expected to be installed in $MORPHDIR/TreeTagger.
=head1 SUBROUTINES
Evaluates the string using the Flemm package, and returns the results.
