RAIN(6)                        BSD Games Manual                        RAIN(6)

NAME
     rain -- animated raindrops display

SYNOPSIS
     rain [-d delay]

DESCRIPTION
     rain is modeled after the VAX/VMS program of the same name.

     To obtain the proper effect, the -d option may be used to specify a delay
     in milliseconds between each update.  Reasonable values are around
     20-200.  The default is based on the terminal speed, computed via the
     following formula:

           delay = speed / 9600 - 1

     As with any curses(3) program, the TERM environment variable must be set
     (and exported) to the type of the terminal being used.
