Nod, apologies I dropped the ball on that one, but having now read 
http://cacm.acm.org/about-communications/author-center/acm-copyright-policy/ 
and talked to the other moderators, I think we're OK.  There'll be an email 
invitation to the sandbox shortly.

Nod.

Ultimately it would be nice if:

* The elementary functions could be made generic - it would be a huge help 
in getting other real-number types in Boost.
* The special functions could be merged with our existing (generic) special 
function code base.
