That question and your reply might make a nice FAQ entry.

Another FAQ question that comes to mind is "What is the relationship 
between Boost.Random and the Standard Library's TR1 random numbers?"

I see that N1398 (in the guise of "wg21-propoal.html") is part of the docs, 
but there doesn't seem to be an obvious link to it from index.html.
