GPLOT is a graphics utility program, designed for the processing of CGM
metafiles produced by DI3000, DISSPLA10, DISSPLA11, DRAWCGM,
NCARGKS1 and NCARGKS2.  

Graphics produced by GPLOT can be combined with TEX formatted text by the 
GTEX program.  GTEX can also create output from DVI files for the supported 
drivers including Tektronix, Postscript, and QMS.

This version of GPLOT includes drivers for PostScript, Tektronix
4010/4014/4207/4510, Cleartext CGM, and  BinaryCGM output.  Other device
drivers are available for use at other sites,  including DEC/GKS, Peritek,
Silicon Graphics GL (IRIS), SUN, SUN monochrome,  UIS, X Windows.  GPLOT cannot
handle CGM character-encoded files.

Version:         4.2

VMS usage:       GPLOT metafile/qualifiers, for example:
 
                 GPLOT/DEV=PS myfile.cgm
                   for PostScript output to the file "myfile.PS".
                 GPLOT/SCREEN=4010 myfile.cgm
                   for Tektronix 4010 output to the screen.
                 GPLOT/CLEAR_TEXT/DEV=PS myfile.cgmc
                   to create PostScript from a CGM clear text file.
                 GPLOT/CLEAR_TEXT/DEV=CGMB myfile.cgmc
                   to create a CGM binary file from a clear text file.
                 GPLOT/DEV=CGMC myfile.cgm
                   to create a CGM clear text from a CGM binary file.
 


Legal Status of code:

GPLOT is not public domain, shareware, or any other kind of ware.  Every
module is copyrighted and you are being given free license to do
whatever you want with it at your site, or to redistribute TOTALLY
UNCHANGED AND WITHOUT CHARGE (except for reasonable media cost) to
someone who can't get it any other way.  It is is copyrighted for 3
reasons

1) So that some company can't put their name on it, maybe copyright it and
then sell it. It does happen; it happened to me, it happened to NCAR.
This is annoying.

2) It's policy at the Pittsburgh Supercomputing Center. This is wise.

3) So that I don't spend the rest of my life chasing down bug reports
from redistributed, hacked code, perhaps with spurious version numbers.
Also so that I can make sure everyone has the current version. This is
essential. 

If anyone wants to make a complete new device driver and redistribute
it, that's fine since it should have no interaction with the rest of
the system.

Bug reports:

I want 'em. I am most interested in CGM files that contain elements, or
combinations of elements, that I have never seen and may not be
handling well. I am not interested in people who give me back 20,000
lines of code and say "I've modified it to be better, why don't you use
this", I do want reports that tell me I have a bug in line such and
such, perhaps with a fix. I'm also interested in any new headers, so
long as they can be uniquely identified.

With this release, maintenance of GPLOT will be taken over by Anjana
Kar, kar@b.psc.edu. Please send requests/bug reports to her, but be
gentle, she is saving my life here.
