I have several versions of MSVC installed, and want to select which
version to use in the command line. I found this:

But trying this by invoking

bjam msvc-6

results in:

c:/boost/tools/build/v2/build\feature.jam:272: in implied-subfeature

error: "6" is not a known subfeature value of <toolset>msvc

bjam --version, prints:
