I manually went through all remaining USE_GROFF ports and briefly checked whether groff was in fact still required. This revealed a number of ports that have man pages that are simply broken.
These need fixing: games/dungeon-crawl ' at start of line games/wanderer ' at start of line games/xasteroids contributors lang/kawa preformatted lang/ruby/2.2 not in roff format mail/sma mdoc net/tclcurl ' at start of line net/zsync . at start of line security/aircrack-ng ' at start of line textproc/filepp escaping Then there are a few candidates where the outputs of groff and mandoc disagree, but it isn't immediately obvious which version is the intended one: lang/ruby/{1.9,2.0,2.1} mail/faces mail/mixmaster textproc/glimpse -- Christian "naddy" Weisgerber na...@mips.inka.de
