Ah! I was trying things like toolset="msvc borland"

None of the http://www.boost.org/doc/html/bbv2/tutorial.html hello world 
examples invoke bjam with multiple requests. None even invoke with a 
single toolset request. bjam --help and its variants don't offer any 
help either.

Also, it is hard to find the link to the html docs. From the boost.org 
main page, you have to know that Boost.Build is considered a "tool".

Once you figure that out, and get to the 
http://www.boost.org/tools/build/v2/index.html page, the Quick access 
section has a line that reads "Documentation (PDF)", with 
"Documentation" linked to the HTML version and "PDF" linked to the PDF 
version. I had no idea there was an HTML version until I say your 
reference below. Apparently every time I have clicked on "PDF" rather 
than "Documentation". It would be helpful if you changed the line to 
"Documentation (HTML, PDF)" with appropriate links.

I'll rephrase the question. How do I apply a compiler switch in my 
Jamfile to builds for one specific toolset. How do I apply the switch 
for that toolset, but only on one specific platform?

That was one of the sections I looked at. Not sure why it confused me. 
It would be a little easier if the full command line (beginning with 
"bjam") was shown.
