Dear joerg and DAK people,

I wrote a section 3.9 in the documentation
http://debdelta.debian.net/html/index.html that outlines two methods;
the first is the complex method (that AFAICR  joerg did not like); the
method in 3.9.2 is instead a simpler proposal: what do you think?

the proposal in 3.9.2 should be able to do that .
