USAGE: fitpolyg infile outimg [-t THRESHOLD] [-c] [-w file] [-L]

fitpolyg performs polygonal line fitting to image
lines; straight line fits are made to portions of each segment
to best approximate the chain of points comprising the segment;
a segment is a chain of points between features, either
endpoint features or junction features.

ARGUMENTS:
    infile: input filename (PCC)
    outimg: output image filename (TIF)

OPTIONS:
  -t THRESH: threshold on error for polygonal fit (default = 5);
             the smaller is this threshold, the closer will be the
             polygonal fit to the original data, but the more straight
             line fit segments will be required.
         -c: when set, prints out the (x,y) coordinates of the
             polygonal fit endlines.
    -w file: save line segment data to a file(.seg) for analysis by xsgll
         -L: print Software License for this module
