Do note that there's no -- before the toolset parameter, and that bjam
completely ignores most of the environment it's in, particularly the
flavor of command prompt you're in and which vcvars you might have
invoked.

It accurately detects through the registry and other shenanigans which
compiler versions you've got installed and exposes them properly through
the toolset parameter, which you use like:

bjam toolset=msvc-9.0

This has many fine benfits, like being able to build for multiple
address models at the same time, as well as being able to target
multiple toolsets easily in batch files, simply through invoking bjam
with different toolset= parameters.

And please, do not top-post, and try to strip down the massive
multi-line sig.
