>how does 'ralpage' compare to ghostscript 2.0 (available on prep.ai.mit.edu).

gs2.0 was able to preview some things that ralpage didn't.  (dvi2ps
output, including the psfig/TeX manual), and MacDraw output.  gs2.0
croaked a few pages into the psfig/troff manual (output of
transcript2.1 psdit), but ralpage was so slow on the images on the
first page, I gave up on it.  gs2.0 doesn't like something in the
starlines example (possibly the fact that I don't have the fonts
installed -- using ugly_r.gsf only)

On some things, gs2.0 is much faster.  It generally seems to use less
CPU time, but sometimes seems to use more real time, perhaps because
it's doing things that the X server does more slowly?  Some timings on
an SGI 4D/240 driving a 3/50 display (an R4 server, compiled with gcc):

gs:

real       36.7

sys         1.2

ralpage:

real     1:05.4
user       17.6
sys         3.2

ralpage:

user        4.2
sys         2.0


  a manual page, formatted with ditroff/transcript2.1

gs:

real       16.3
user        1.2
sys         0.5

ralpage:

real        9.1
user        3.7
sys         1.4

All in all, this release of Ghostscript is an amazing improvement over
the last version.
