USAGE: xvora infile outimg [-d] [-k S] [-p a] [-b] [-e] [-a] [-l]
                   [-n nbins] [-i f] [-f f] [-s f] [-w f] [-L]

xvora extracts statistics of a given Voronoi diagram from
the representation stored in a file of type .vdt; a histogram
may be contructed from various quantities

ARGUMENTS:
        infile: input filename (ASCII) produced by xvor;
                .vdt (Voronoi data)
             or .ddt (Delaunay data)
        outimg: output image filename (TIF)

OPTIONS:
    -d: show input data
  -k S: construct k-NN shells, k<=S (default=2)
  -p a: enable labeling; a is a string, as follows:
        a=nall: enable numbering of all sites
        a=n57: enable numbering of 5-fold, 7-fold sites
        a=n57a: ->in addition, mark active AOI
    -b: no border strip

        construct histogram for:
    -e: edge number (per Voronoi polygon)
    -a: polygon area
    -l: nn-distance (edge bisector length)
  -n n: set number of bins to n (default:=10)
  -i f: set initial value to f(float)
  -f f: set final value to f(float)
    -s: evaluate nn-distance statistics function Q = Q(t)

  -w f: write data to file
        f=h: hist data --> file of type .hdt
        f=s: site topol data --> file of type .std
        f=p: poly topol data --> file of type .ptd
    -L: print Software License for this module
