This transcript is not from GSView but it does show most of the usual
things you can do in those programs...

You fire up GSView. It works, but unfortunately the print is so big
that you can't see an entire line without scrolling left and right.
Your blood pressure goes up.

GSView is a nice program written by GNU folks. It lets you view
PostScript files without printing them. Looking closer, you notice a
vertical row of buttons along the left border of the window.
>examine buttons
One of the buttons has an intricate engraving depicting a lens with
plus sign. You remember how you used to have a magnifying glass just
like this when you were a child--you used to show a "big eye" to your
friends by putting the glass in front of your eyes. As the
reminiscences pass, you notice a button next to it bearing a picture
of a lens with a minus sign. You wonder what a lens that diminishes
instead of magnifying could be useful for.
