Sometimes computers try to be too clever for their own good. Take this illustration for instance.
Just because so many of the labels are rotated through ninety degrees, FrameMaker seems to
want to insist on telling the postscript file that I would find it more convenient to see this page
displayed in landscape, rotated by ninety degrees. Well I wouldn’t. So I am putting in all this text
just to weight the average in this direction.
