Ok, now I'm looking at your diagram, which is now part of 
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/boost/boost/tools/build/new/m2-transformations.txt?rev=HEAD&content-type=text/vnd.viewcvs-markup
to see what problems it presents for us.

I've some initial questions, and would appreciate if you could clarify them

1. Is *.bsc file created for each executable file, or for the whole project?
2. Is creation of precompiled headers an explicit operation? I.e. would it be 
reasonable to require something like:

precompiled_headers my_project_pch : stdafx.cpp ;

3. How files compiled with and without precompiled headers are separated? Can 
we assume that sources for each main target all either use PCH or don't use 
them. That would allow to write

lib a : a.cpp ;
lib b : b.cpp my_project_pch ;

Or is finer granularity required?

TIA,
Volodya
