[boost] Boost.Build v2 with VC8

How do you do it? I've tried adding using msvc : 8.0 to user.config and I've tried using msvc : vc-8_0 since that didn't appear to work. At that point I got the message that the python lib wouldn't be build - but I've set both PYTHON_ROOT and PYTHON_VERSION to the satisfaction of Boost.Build v1. Can someone please tell me what to configure and the exact command line I should use to build it? I've already spent 2 hours running in circles in the docs and that doesn't seem to get me anywhere. Thanks, Johan
