Correct... Other than the initial use of bjam to build+install.

Correct... The unversioned names are optimally hard-links to the
versioned names. Since link support is less than stellar on Windows, the
build does a copy instead on the platform. But on *nix it does a real

I don't expect it. And it doesn't create those for me unless I "stage"
or "install".

I think you are confusing the non-install builds with the install ones.
If you use the same tree to do testing, examples, or other build you
will get bare names (bare = unversion, no variant, no toolset).

If you want to see what the build+install does I suggest you locate it
apart from the Boost tree with the "--builddir" option, and possibly
"--prefix", and "--stagedir".

Additionally a new option this time around is "--layout". Which system
integrators can use as "--layout=system" to get mostly untagged names.
