# The following set of gnu commands can be used 
# to plot surfaces and contour plots. The 2 and 3
# dimensional fortran programs produce data in the 
# form
#
# x   y   f1  f2  ...
#
# where x and y define the coordinates of an
# array of points in the plane X-Y, and fi is
# a quantity to plot. As an example below we plot
# a file 'e3wcu2.out' using x, y and f1
