I was a bit miffed by your outraged response to my explanatory reply.
I thought I was being helpful and instead I got "when did you stop
beating your wife?" questions like #2 and #3 below.  How is anyone
supposed to answer those?

That question wasn't clear from your posting.  As far as I could tell
you were asking how to "just run bjam with no options and get the libs
built with thread support".  Maybe if you applied a little less heat
it would be easier to help you.  Sarcastic rhetoric may have hurt the
comprehensibility of your request.

http://www.boost.org/tools/build/build_system.htm documents how to
set the build request on the command-line, and you can in fact find a
mention of <threading>multi in there if you dig hard enough.

Ask me a question which is more than just a way to vent your
frustration and I'm happy to try to answer it.

Oh, so *that's* where the visions came from! ;-)
