Usage Notes
gxepsis to 
    create a grayscale plot on a white background. The GrADS default rainbow colors 
    (color numbers 2 to 14) are converted into appropriate grey shades. User-defined 
    colors (numbers above 15) are translated to greyscale intensity based on their 
    green content only. 
  Examples

gxeps -rc -i mytest.mf -o mytest.ps
mytest.mf 
    to a color plot on black background and outputs the 
    result to PostScript file mytest.ps.
