       An affine fractal is computed via the  Multiple  Reduction
       Copy Machine Algorithm.  The rules must be supplied from a
       file with each line consisting of six  values  (A-F)  such
       that the values of A-D describe a 2x2 matrix (A, B; C, D),
       while E and F describes a 2x1 column vector (E; F).


       -infile string
              Data input file.

       -width integer
              Width of the plot in pixels.

       -height integer
              Height of the plot in pixels.

       -depth integer
              Depth of recursive calls.

       -border integer
              Number of pixels in border.

       -bw double
              Width of the seed box.

       -bh double
              Height of the seed box.

       -L     Draw an 'L' in each box?

       -term string
              How to plot points.

       -inv   Invert colors?

       -mag integer
              Magnification factor.


       There is a shell script called 'ifscma' supplied with  the
       source code that has a simple interface that allows you to
       reference sets of predefined rules by name.  You may  also

       wish  to  see the author's book, "The Computational Beauty
       of Nature," for some more examples.


       No sanity checks are performed to make sure  that  any  of
       the options make sense.

       The  maximum  number  of affine rules is determined by the
       constant MAXRULES, which you  may  need  to  adjust  under
       exceptional circumstances.
