+ * Display something vaguely comprehensible in the event of a totally unrecoverable error.
+ * Does not assume access to *anything*; no globals, no autloader, no database, no localisation.
+ * Safe for PHP4 (and putting this here means that WebStart.php and GlobalSettings.php
+ * no longer need to be).
+ *
+ * Calling this function kills execution immediately.
+ *
+ * @param $entryPoint String Which entry point we're protecting. One of:
+ * - index.php
+ * - load.php
+ * - api.php
+ * - cli
+ *
+ * @note Since we can't rely on anything, the minimum PHP versions and MW current
+ * version are hardcoded here
