 I'll toss out my opinion for what it is worth as a complete outsider
looking in..

I _still_ do not understand what Boost.Build is. I always figured it
was just part of the Boost project and was the custom build system
used by Boost, hence the name Boost.Build and bjam but I had no idea
you could use it separately. Let me see if I can figure this out using
what I know: CMake:

So CMake has the actual CMake executable tool, this seems equivalent
to bjam. Then CMake has a bunch of "modules" that help do things like
find libraries, test for symbols, install stuff. I guess those are
like the Boost.Build system or the Boost.Build "libraries"? Then you
write your own cmake files specific to your project which I guess is
like the part where you write your own project.bjam files? Is that
right? Do I actually need Boost to run Boost.Build? Does Boost have
anything to do with Boost.Build? If not then I would pick an entirely
different name in order to provide clear separation between the Boost
project and the Boost.Build build system.

  Hope that provides some insight
