The trick is to put a regular:

    use IO::Prompter;

at the top of your program and a sneaky:

    use IO::Prompter <<'END_OF_AUTOMATED_INPUT'
    This will be typed in automatically for you
    Et cetera
    Et cetera
    END_OF_AUTOMATED_INPUT

way down the bottom of the program (e.g. after a hundred empty lines),
where it will never appear on screen.

The IO::Prompter distribution includes a program: demo/demo_fake.pl
which illustrates the technique.
