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


       pyro accepts the following options:

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

       -root   Draw on the root window.

               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

       -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).


       DISPLAY to get the default host and display number.

               to get the name of a resource file that  overrides  the  global
               resources stored in the RESOURCE_MANAGER property.
