for a set of points in the plane using Fortune's algorithm.
[Fortune 1984]

ARGUMENTS:
        infile: input filename (.vin) (ASCII)
                produced by spp or xah; assumes y-sorted
                site coordinates unless option -s invoked.
        outimg: output image filename (TIF)

OPTIONS:
   -w file : write output to file ( .vdt) as well as stdout
         -s: y-sort data in input file
         -t: perform Delaunay triangulation
         -g: debug mode
         -L: print Software License for this module
