/**
 * Create the index.php file based on the outputted index.html
 *
 * This file will remove the html meta tags and replace it with
 * a php script that automatically outputs the meta tags based on
 * the current url. Values are populated from the share.json file.
 *
 * Replacing the meta tags relies on the <title /> tag being the
 * first tag, and the <meta name="twitter:card" /> tag being the
 * last tag. It will remove all the meta tags between (and including)
 * those 2 tags and replace them with the PHP script.
