You might want to check out 
http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?Boost.Build_V2/MicrosoftVCProjMigration 
in the Wiki. This is still under construction and would love some 
help/feedback on it. Note that some of the documentation in there will refer 
to the latest CVS version of BBv2.

BBv2 has support for profiling, instead of:

bjam msvc-7.1 release

use:

bjam msvc-7.1 profile

It would be better to use <debug-symbols>on instead of using the /Zi switch 
directly. I am not sure what /fixed:no does.

The response files are stored in the build directory. Thus, if you are 
building main.cpp, you will have
bin/msvc-7.1/release/main.obj
bin/msvc-7.1/release/main.obj.rsp
where main.obj.rsp is the response file. This just contains the <include> 
and <define> properties, along with the source files for the target. The 
linker flags should be visible from the link command line.

See above :). If you look in boost/tools/build/v2/tools/builtin.jam (or 
common.jam) and look for the debug, release and profile variant setup, 
that's how it's done ;).
