This statement sounds negative and I meant it to be neutral.
The Makefile/auto* changes are positive moves in the CVS source.
They do simplify things enormously and are a critical step in
getting separate CPU and BSP Kits.

This was intended as a practical statement .. you have a
BSP from CVS and want to use it with 4.6.  The Makefile's are

I agree completely.

I have been trying to track 4.7 improvements and changes on the
website.  If you check out wwwrtems from CVS, see 
htdocs/rtems-4.7/index.html.  The writing isn't the greatest but I 
certainly invite you to explain more about the work you have been doing.

I hope you noticed that your work is at the top of the list.
It should give you some indication of the importance I place onit.
I can't always explain it well but I try. :)

Yes.  I am even fighting this.  I want to tag the SuperCore before I
attempt to merge the 3.5.1 EDF patch/CD I got while in Munich. :)
Adding Doxygen will break the patch even more.
