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.

       -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 100.

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

       -scatter integer
               How  many  particles  should appear when a missile
               explodes.  Default 20.  The actual number used  is
               between N and N+(N/2).

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  the  RESOURCE_MAN-
               AGER property.
