       A bifurcation  diagram  of  the  Henon  system,  which  is
       described  by the equation x(t+1) = A - x(t)^2 + B * x(t -
       1), is plotted  according  to  the  specified  parameters.
       Either  of  the  parameters  (A or B) can be varied in the


       -width integer
              Width of the plot in pixels.

       -height integer
              Height of the plot in pixels.

       -skip integer
              Number of initial points to skip.

       -abmin double
              Smallest value for A (or B).

       -abmax double
              Largest value for A (or B).

       -ab    If TRUE, plot for A; B otherwise.

       -A double
              Value of the A parameter.

       -B double
              Value of the B parameter.

       -factor double
              Multiplicative factor for iterates.

       -ymin double
              Smallest value for y range.

       -ymax double
              Largest value for y range.

       -box integer
              Line width for a box.

       -brmin double
              Smallest r-value for the box.

       -brmax double
              Largest r-value for the box.

       -bymin double
              Smallest value for box y range.

       -bymax double
              Largest value for box y range.

       -inv   Invert all colors?

       -mag integer
              Magnification factor.

       -term string
              How to plot points.


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