*
* The 'postscript' driver produces landscape output 10" wide and 7" high.
* To get a smaller epsf output use 'set size 0.5,0.5',
* 'set term postscript portrait', make only one plot per file
* and change the first line of the postscript file from
* '%!PS-Adobe-2.0' to '%!PS-Adobe-2.0 EPSF-2.0'
* To change font to Times-Roman and font size to 20pts use
* 'set term postscript "Times-Roman" 20'.
