Re: french stemmer

Hi Martin,

I fully understand your point of view. I think, like you write, that 
listing all the possible "errors" language by language would be great 
because we could perhaps find new rules/behaviours . (Moreover it would 
naturaly build an excpetion thesaurus).
With this listing, I would be happy to try to add/modify rules for the 
french stemmer.

Thank you for your wonderful work.
