perhaps you can keep the narrative and just simplify the example a bit? I have nothing against the consistent narrative, it is a nice touch.

Ok, I think I got it now, thanks :). As far as I am concerned, just adding this explanation to the tutorial would be enough.

It seems I got the right version, I checked out from github, not the incubator. My version of the Jamfile has these lines

project
    : requirements
      <toolset>gcc:<cxxflags>-std=c++11
      <toolset>clang:<cxxflags>-std=c++11
    ;

I am not a Boost.Build expert, but that looks ok to me. Nevertheless, when I run just ./b2 in the "tests" folder, it tries to compile but fails. When I run ./b2 cxxflags=-std=c++11, the tests compile fine.

Best regards,
Hans
