DESCRIPTION

       The  pyro program simulates fireworks, in a way similar to a Macintosh program of the same
       name.

       -window Draw on a newly-created window.  This is the default.

               Install a private colormap for the window.

       -visual visual
               Specify which visual to use.  Legal values are the name of a visual class, or  the
               id number (decimal or hex) of a specific visual.

       -count integer
               How many particles should be allowed on the screen at once.  Default 600.

       -frequency integer
               How often new missiles should launch.  Default 30.

       -scatter integer
               How  many  particles  should  appear  when  a missile explodes.  Default 100.  The
               actual number used is between N and N+(N/2).

       -fps    Display the current frame rate and CPU load.
