Am I missing something here? Last time I looked, NextStep was
completely different than X11. It would seem to me that because they
got something working under NextStep does not mean that doing the same
thing under X11 is possible. I am, frankly, a bit dubious about this
port of DOOM to Linux (at least one that does not like mmap() the video
card or something).
