I just tested both the two new options in bcp.  The modified bcp'ed source code 
and the produced libraries after a plain bjam build of a selected subset of 
boost looks very good.  I have to agree with Artyom, this is great news.  

This give both open and closed source library developers a very nice tool 
which allow use of boost in their library implementation without risking 
polluting the boost namespace for their users. In other words, this make use 
of boost more feasible for a large group of C++ developers which otherwise 
typically would re-invent what they needed.

This would be useful if full side-by-side header support is provided.  But 
that is more involved than just renaming macros.  Also, I think what is in now 
is the more important feature.  

Thank you for adding this John.
