One last note

I pasted the wrong url for the packages with no dependencies

The right one is this
http://catonano.altervista.org/no-deps.txt

I noticed now that this list contains ALSO the broken ones. They have no dependencies, but they shold be excluded from this list

Because I screwed up the data format, the queries are not exactly immediate, they need honing :-/

I will fix this in the future
