All committed. I still have problems with processing the patches
automatically. Can you verify that all has gone to plan.

I'll leave Kresimir to apply this. I don't have a copy of binding at the

I have often thought of using the BoostBook system. But it would be a big
project. It would be very useful if we could use Doxygen to to help keep doc
and source consistent. At the moment Toon and Gunter are most active
regarding documentation. A lot has been done regarding readability but a lot
of work is often require just to get correctness and a good formal
