Usage: node slowbaud.js [-t] baudRate filenames....
-t: The -t option emulates human typing by adjusting the interval function. Instead of a constant interval, a normal distribution is used, so the typing feels less mechanically smooth and more naturally bursty.
baudRate: The baudRate should end up feeling about like a modem connection of that rate. Characters per second is 1/9 of that rate (we assume no parity, 8 data bits and 1 stop bit). If you want something more like a fast, sustained typing speed, go for 70-100.
filenames: Specify as many filenames as you like. They should, of course, be plain text.
