    This directory contains version 2 of the additional files you'll need
to get gnuplot3.0 to display it's postscript directly to a window instead of
going through the klunky process of writing the postscript to a file and
launching Previewer to view the file.  Note that all input is still done at the
shell level! Fancier NeXTStep interfaces will be a future project.
    This version is faster and leaner than the old method.  It also does
not eat up swap space like the older version (this was particularly noticeable
when doing animation-like plots).  To do this I used DPS function calls instead
of creating a NXImage and compositing the stream of commands. I based my code
on the program called "epsview" in the hackkit tar file on the archive servers.
    The next_dps.trm (next terminal) is basically the post.trm (postscript
terminal) with the fprintf replaced by DPSPrintf and outfile by the
DPSContext d.  You'll also see that I also used some code (with modifications)
from David S. Joerg's MovieApp.  Using the DPS functions enabled me to slim
down the EpsViewer.[hm] and EPSView.[hm] files.
    No claim is made to code elegance or to it being a good example of
objective-c coding.  This is my first (well, second, sort of) objective-c
program. It seems to work for me. Any constructive criticism would be
appreciated.  I can be reached at [e-mail]

cheers!
