        !            38: .SH DESCRIPTION
        !            39: The
        !            40: .I factor
        !            41: utility will factor integers between -2147483648 and 2147483647 inclusive.
        !            42: When a number is factored, it is printed, followed by a ``:'',
        !            43: and the list of factors on a single line.
        !            44: Factors are listed in ascending order, and are preceded by a space.
        !            45: If a factor divides a value more than once, it will be printed
        !            46: more than once.
        !            47: .PP
        !            48: When
        !            49: .I factor
        !            50: is invoked with one or more arguments,
        !            51: each argument will be factored.
        !            52: .PP
        !            53: When
        !            54: .I factor
        !            55: is invoked with no arguments,
        !            56: .I factor
        !            57: reads numbers, one per line, from standard input, until end of file or error.
        !            58: Leading white-space and empty lines are ignored.
        !            59: Numbers may be preceded by a single - or +.
        !            60: Numbers are terminated by a non-digit character (such as a newline).
        !            61: After a number is read, it is factored.
        !            62: Input lines must not be longer than 255 characters.
        !            63: .PP

        !            65: .I primes
        !            66: utility prints primes in ascending order, one per line, starting at or above
        !            67: .B start
        !            68: and continuing until, but not including

        !            76: value must not be greater than 4294967295.
        !            77: The default value of
        !            78: .B stop
        !            79: is 4294967295.

        !            86: .B Stop
        !            87: is taken to be 4294967295.

        !            92: .B start

        !            94: The input line must not be longer than 255 characters.
        !            95: .SH DIAGNOSTICS
        !            96: Out of range or invalid input results in `ouch' being
