Sigh...
Thanks for all your responses. Yes I did check out the fact pages, I just did not check them carefully enough. I was so concentrated on finding the information that I... "missed" the left hand links to more FAQs. In the words of a certain person: "D'Oh!". Sorry about that and taking up some of your time and e-mail space.
Encore merci.
