Ok, I like it.

I did replace my changelog with your proposed one, but I've left the
example output from xenalyze in place.

Not sure whether you were suggesting to also kill that part. I do think
it's useful so I left it there. But if you want it removed too, I can
live with that, so just ask. :-)

Thanks and Regards,
Dario
