Edward,
Let me use an example with shorter paths, so that I can actually type on a small screen. Say you have Boost source in /tmp/boost, then the build-directory property in jamroot will cause build to go to /tmp/boost/bin.v2/gcc/...
If you specify --build-dir=/tmp/build, that will change to /tmp/build/boost/gcc/... - note that bin.v2 is completely overridden, and 'boost' is added, taken from project declaration in Jamroot. This allows --build-dir to work if the build spans multiple Jamroot files.
Stage and install dirs are not handled by Boost.Build, but by Boost C++ libraries. If you run b2 --help in Boost C++ root, you will see two options that control those directories.
HTH,
Volodya

I am not sure what this means in the documentation.
If currently my local Boost git repository from source is at
C:/Programming/VersionControl/modular-boost do I specify the --build-dir
as 'C:/Programming/VersionControl/modular-boost' to ensure that the
output of tests goto C:/Programming/VersionControl/modular-boost/bin.v2
? What about install and stage directories ? Do they then go to
sub-directories relative to C:/Programming/VersionControl/modular-boost
if I set --build-dir as 'C:/Programming/VersionControl/modular-boost' ?
