... and the ports tree is actually ready to switch. Any port that requires groff just need to set USE_GROFF=Yes to - have a build depends on the groff port - have pkg_create format pages using the groff port "behind the scenes".
Note that this is transparent revision-wise, there's absolutely no need to bump anything, since that's a build-depends, and register-plist is already aware of the equivalence between manN/foo.N and catN/foo.0 So, it's just a question of a massive commit to tag all ports that have manpages with USE_GROFF, do a build and check that everything is fine. Then we can slowly switch everything that's happy with it back to mandoc.
