Qt4 questions

Hi,
I've just tried the recently released Qt4, and have a couple of question about 
best modifications to qt.jam for Qt users out there.

1. Qt is now split into several libraries. Should we do the same in 
Boost.Build, so that users will write:

exe hello : hello.cpp /qt//Qtgui ;

? This will mean that Jamfiles built against Qt4 will be incompatible with 
Jamfiles using Qt3, but those versions are not source compatible anyway.

2. The include directory has subdirectories "Qt" with QApplication, QWidget 
and other similar headers (without .h), and subdirectories for each 
component. We clearly should add include path of <qt-prefix>/include/Qt, but 
what about component dirs. IOW, should it be possible to

#include <QtGui/qapplication.h>

?

3. Finally, how do we know we're using Qt4? Should we add version parameter to 
qt.init and require that it's always passed? Or there's another way to detect 
Qt version?
