DESCRIPTION

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

OPTIONS

       pyro accepts the following options:

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

       --root  Draw on the root window.

       --window-id number
               Draw on the specified window.

       --mono  If on a color display, pretend we're on a monochrome display.

       --install
               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.

       --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.

ENVIRONMENT

       DISPLAY to get the default host and display number.

       XENVIRONMENT
               to get the name of a resource file that overrides the global resources  stored  in
