It's ben indeed. It also creates the html page, but before doing that it
calculates all the affected packages based on the .ben file (i.e. this one
https://release.debian.org/transitions/config/ongoing/r-base-3.5.ben) and
whether they are good, bad, both (partial) or none (unknown), and the dependency
levels (the ordered set).
