[Boost-build] VC11 November CTP

With the (very) recent release of the VC11 November CTP*, I wonder if there
is a way to currently (or plans to support in the near future) get boost
build to use the new toolset to play around? The problem is that it's
installed side-by-side the RTM compiler (as it's a preview) without a new
command prompt environment which correctly sets up the env vars.

This could be worked around, but it can only be done after the env vars
have already been set by the VC scripts (as they need to be overridden), as
described in the comments on the linked website (quoted here):

> CTP\include;%INCLUDE%
> Everything should work after that.

Is there a way to have Boost.Build set these env vars after the environment
has been initialized, or is it 'too late' by then?

Thanks.
