RAIN(6) Games Manual RAIN(6)
rain - animated raindrops display
rain's display is modeled after the VAX/VMS program of the same name.
The terminal has to be set for 9600 baud to obtain the proper effect.
As with all programs that use termcap, the TERM environment variable
must be set (and exported) to the type of the terminal being used.
