rain - animated raindrops display
rain [-d delay]
rain is modeled after the VAX/VMS program of the same name.
To obtain
the proper effect, either the terminal must be set for 9600
baud or the
-d option must be used to specify a delay, in milliseconds,
between each
update. A reasonable delay is 120; the default is 0.
As with any curses(3) program, the TERM environment variable
must be set
(and exported) to the type of the terminal being used.
