The current state of that TR is at <
http://svn.boost.org/svn/boost/sandbox/tree/>. Although a few notes about
it..

* The code is old and since Bernhard wrote it I don't know at the moment
the state of closely it follows the TR. Since most of it was written before
the TR.

* I've been updating the docs rather slowly (too many other projects going
on). But I'm hoping to get an update of the TR done by in the Spring. And
work again on the implementation after that.
