Yes, but common sense is just so uncommon these days :-).

Does "local testing * of the submodule*"  include running the unit-tests of
the the other submodules to see if you've broken anything in someone elses
submodule that depends on yours?  And BTW, I was Googling and looking
through Boost.Build documentation and couldn't figure out how to easily run
all the tests for all the libraries.  I would assume there is a target you
could pass b2 to run all the unit-tests.  What is it?

Wow, that's a lot of combinations.  Is that the "official" Boost policy,
i.e. is there a link on the web-site I can read this?  Will that be the
official policy for all Boost libraries or can individual libraries define
their own?
