/**
 * Mr. Robot Season 2 easter egg website email alert cronjob
 * (Note: requires your PHP to be able to send emails (of course)!)
 *
 * 1. Download this script. Browser download: https://gist.github.com/eyecatchup/f5f5929f57b22fc1b37ef516d675ac92/download/
 *    Or, for the console users:
 * # wget --no-check-certificate https://gist.github.com/eyecatchup/f5f5929f57b22fc1b37ef516d675ac92/raw/watchRobot.cron.php
 *
 * 2. Set the value for the variable $notifyEmailAddress to your email address.
 *
 * 3. Create a new cronjob (for a Windows Xampp stack alternative see: http://stackoverflow.com/a/4231634/624466).
 *    On your console, type:
 * # crontab -e
 *
 * 4. Paste the following (adjust script/logfile path):
 * 0 * * * * php /absolute/path/to/script.php >> /absolute/path/to/cronjob.log
 *
 * Exit crontab and you're all set. You'll get an email as soon as there's a new Mr. Robot EE site to checkout.
