             Release of GPLOT (4.3b2) --  Oct. 30, 1991

This is the official release of GPLOT 4.3b2 available through anonymous
ftp from ftp.psc.edu:/pub/gplot. This is a small bug fix version, and 
differs slightly from gplot 4.3b1. 

This release also includes the 3.3 release of CGMGen and DrawCGM software.
To get the release information for DRAWCGM, please take a look at the file
README.DRAWCGM.

If you are interested in getting the HDF driver for GPLOT, please get
the file README.HDF and hdfdev.tar.Z.

The files necessary to create GPLOT are available in two forms.  

(1) If you are on a Unix system, FTP the file gplot.tar (using binary 
    format), move it into its own directory (gplot), and un-tar it 
    using the command 'tar xf gplot.tar'. 
   
    The Makefile contains a complete Unix makefile. You will need to modify 
    the Makefile to include a workstation driver of your choice according to 
    the included directions and use it to make gplot and drawcgm. Please 
    read the instructions before making any changes to the Makefile.

    A note about the two X window drivers : xl and xws
    ---------------------------------------------------
    xl works great with simple cgm files, and is fast, but does not have
    colormaps installed. 
    xws has colormaps and good dithering techniques. So it can be used for
    cell array cgm files, but the rendering process can be slow.
   
    The interfaces "gplotdw", "gplotaw" and "gplotm" use xl by default.
    If you wish to change that to use xws, you will need to edit the 
    Makefile appropriately. 
     
        
(2) If you are on a VMS system, copy all the files in the 'src' directory, 
    and use the descrip.mms file (if you are running MMS) or use the file
    MAKEGPLOT.COM to construct GPLOT. 


When you take a copy of GPLOT, please send mail to Anjana Kar (kar@a.psc.edu) 
so we can add you to our mailing list.  Bug reports should be sent to Anjana
at that address.
