No, I was joking, but many a true word spoke in jest -

it IS a vital part of the documentation.
(though perhaps it need not be part of the Boost *distribution*,
which reaises an interesting question about where background material should live. It needs to be somewhere *permanent* - which
perhaps is not the intention or reality for the Boost Vault?)

You will find essential John Maddock's patches for NTL used with the Math Toolkit - in the sandbox until 1.35 is out. And it would
be really nice if we could persuade the author Victor Shoup to release at least the base part of NTL under the Boost license - is
GPL at present.

Good luck.
