modified by any immediately following transformation options.

Options
  -h,--help this help message (run 'off_util -H help' for general help)
  --version version information
  -c <num>  a unit circle arrangement of num pins
  -l <num>  a 2 unit line arrangement of num pins
  -p <crds> line end points coordinates, six numbers separated by commas
  -T <tran> translate, three numbers separated by commas which are
            used as the x, y and z displacements
  -R <rot>  rotate about an axis, three, four or six numbers separated by
            commas. If three numbers these are angles (degrees) to rotate
            about the x, y and z axes. If four numbers, the first three
            are a direction vector for the axis, the last number is the
            angle (degrees) to rotate. If six numbers, these are two
            vectors and rotate to carry the first to the second
  -M <norm> reflect in a plane, three numbers separated by commas which
            give a vector normal to the plane of reflection.
  -S <scal> scale, one, three or four numbers separated by commas. If one
            number then scale by this factor in all directions. If three
            numbers these are the factors to scale along the x, y and
            z axes. If four numbers, the first three are a direction
            vector for the scaling, the last number is the factor to scale
  -I        invert
  -o <file> write output to file (default: write to standard output)
