+.Sh NAME
+.Nm rain
+.Nd animated raindrops display
+.Sh SYNOPSIS
+.Nm
+.Op Fl d Ar delay
+.Sh DESCRIPTION
+The output of
+.Nm
+is modeled after the
+.Tn VAX/VMS
+program of the same name.
+To obtain the proper effect, either the terminal must be set for 9600
+baud or the
+.Fl d
+option must be used to specify a delay, in milliseconds, between each
+update.
+A reasonable delay is 120; the default is 0.
