WP multisite upgrade script

<?php
/**
 * WordPress Multisite upgrade script
 *
 * IMPORTANT: While a simple safeguard has been added to the script,
 * you'll want to add another layer that prevents this script from 
 * being called via the browser.
 *
 * Usage:
 * 1) Place in the root of your install (or another place, but modify the wp-load.php path to match)
 * 2) Modify the $_SERVER['HTTP_HOST'] variable below
 * 3) > php cli-ms-upgrade.php
