Synchronous [Readline](http://nodejs.org/api/readline.html) for interactively running to have a conversation with the user via a console(TTY). Synchronous [Readline](http://nodejs.org/api/readline.html) for interactively running to have a conversation with the user via a console(TTY).
readlineSync tries to make your script have a conversation with the user via a console, even when the input/output is redirected like `your-script <foo.dat >bar.log`. readlineSync tries to let your script have a conversation with the user via a console, even when the input/output is redirected like `your-script <foo.dat >bar.log`.
