No, a "comeau toolset" file.

A file which interfaces Boost.Build with the Comeau compiler.

There's no bjam v2, only Boost.Build v2, but yeah, BBv2 doesn't
support all the same toolsets as v1 yet.

You seem to overlook the fact that BBv2 is pre-release software. It
isn't reasonable to expect it to have complete documentation or
support for everything in v1 yet. We're going to get it to support
the same toolsets as v1 does before it is released.

That's one way to put it. It's a big improvement, and also a fairly

I guess natural assumptions aren't always safe assumptions ;->

It won't work until we have the v2 Comeau toolset. Maybe you should
try BBv1 if you want BBv1 command-line compatibility ;-)

BBv2 from CVS may use features not in any released bjam executable.
The solution is to rebuild bjam.
