What I'm saying is that this doesn't meat the requirement:

cd boost-root-nmake-vc80
cmake --use-nmake-vc80 ..\boost-root
NMAKE
NMAKE test
NMAKE install
cd boost-root-nmake-vc71
cmake --use-nmake-vc71 ..\boost-root
NMAKE
NMAKE test
NMAKE install
cd boost-root-gmake-gcc345
cmake --use-gmake-gcc345 ..\boost-root
gmake
gmake test
gmake install

Why should we give up the current:

cd boost-root
bjam msvc-8.0 test install
bjam msvc-7.1 test install
bjam gcc-3.4.5 test install

(ignoring that those could be done in one command for comparison sake)

?

The *only* benefit I see from using generation system like cmake, or 
wxWidget bakefile, is for end users where the Boost release manager 
creates a bunch of makefiles, nmake files, vc project files, etc. and 
hence the user doesn't have to use cmake, or bakefile.
