How does the French school deal with dietary restrictions for medical, ethical and religious reasons?

Swedish schools are pretty accomodating on all these grounds (though I would say that is pretty recent). I even saw an article with a parent who had brought up her kids on all organic food suing the municipality. I even think she won, which means organic food for her kids. I think that started about twenty years ago with offering vegetarian food which also meant giving a no-beef and no-pork alternative.
