-UFO: Alien Invasion
+ufoai (UFO: Alien Invasion)
 
 This is a squad based tactical strategy game, heavily inspired by the
 X-COM PC games, but with twist. Old veterans will appreciate how the

 It runs on a modified Quake 2 game engine.
 
-If you want to try out the game editor (uforadiant), install gtksourceview

+If you're going to install the package on a host whose CPU lacks

+Optional *broken* stuff: The map editor for UFO:AI is called
+uforadiant. It's disabled by default because it's broken: it
+segfaults on startup on Slackware-current (October 2021) and the
+SlackBuild maintainer hasn't figured out why, yet. If you want
+to try uforadiant, install the optional dependencies gtkglext and
+gtksourceview, then build with RADIANT=yes in the environment. If you
+try this and uforadiant *doesn't* segfault for you, *please* contact
+the maintainer!
