 which is probably more relevant for DoseFinding debugging
 than the Debian specific things below. )

@Dirk: Could you please be more verbose in how far that link is a sign
that DoseFinding 0.9-16 works with multcomp 1.4-10.  

@Paul: I think its not really relevant for Buster release since multcomp
will not migrate due to freeze so for the moment I will not do anthing
for the moment (may be after Buster release DoseFinding maintainers at
CRAN found a solution - otherwise we need to do something about this).

That's correct.  But due to the use in the autopkgtest and the test
script is provided in the doc directory as example for users dh-r
upgrades those Suggests to Recommends[1].

Kind regards

       Andreas.

| multcomp/1.4-10-1. I.e. due to versioned dependencies or breaks/conflicts.
