[Openstreetmap] Saratlas: free database of French and Swiss autoroutes

[Rev Simon Rumble]

I just discovered this mapping site for French and Swiss motorways. 
Quite impressively detailed -- these guys are real anoraks (geeks,
enthusiast for the non-Brits) for their roads.

I can't find any information about licensing, but if it's under a free
license, would make a valuable inclusion in OSM.  I'm happy to make
contact in a week's time -- I'm actually off to France this afternoon
-- but someone might want to remind me.
