+ * Example #1: When viewing http://example.com/path/alias, this function

+ * Example #2: When viewing http://example.com/node/306, if that node
+ * has path alias of 'path/alias', this function would return "path/alias".

+ * Example #2: When viewing http://example.com/drupalfolder/node/306 this
+ * function would still return "path/alias" and base_path() would return
+ * "/drupalfolder/".
+ *
+ * NOTE: This function is not available in hook_boot and you should use
+ * $_GET['q'] instead. Calling drupal_bootstrap(DRUPAL_BOOTSTRAP_PATH) makes
+ * this function available with a return value of "path/alias" or
+ * "node/306" if no path alias is set for that node.
+ *
+ * @return
+ *   The current Drupal path alias if any, otherwise the current URL path.
