First, a general comment -- many readers have software that will chop
off long lines without carriage returns, making messages like yours
unreadable. Please put carriage returns at the normal line break
points, rather than assuming that the software will do it for
everybody.

GoScript isn't a pre-processor; it's a complete (well, except that
they haven't implemented the 'setscreen' operator yet) interpreter for
PostScript. It does precisely the same thing that the PostScript
interpreter built into a Laserwriter does -- takes PostScript input
and turns it into a raster image that can be pumped directly to the
print engine.

GoScript 3.0 has a number of different output drivers; when it is
configured, you specify what type of display you have, and the '/w'
flag causes the output to be displayed on the screen. Another flag
will let you use an output driver different from the normal printer
driver to either drive a different printer or output TIFF or PCX
files.
