     If the script reads from stdin, expect is overkill, and the pipe
     will do the job. Expect's main use is for commands that read
     directly from the terminal (/dev/tty).

     Besides, if it's a scipt, it presumably can be changed, either so
     that it does read from stdin, or else doesn't ask at all.
