 /**
- * Elgg web services handler.
+ * Services handler.
  *
- * @package Elgg
- * @subpackage Core
- * @author Curverider Ltd
- * @link http://elgg.org/
+ * This file dispatches requests to web services.  It is called via a URL rewrite
+ * in .htaccess from http://site/services/api/handler/response_format/request.
+ * The first element after 'services/api/' is the service handler name as
+ * registered by {@link register_service_handler()}.
+ *
+ * The remaining string is then passed to the {@link service_handler()}
+ * which explodes by /, extracts the first element as the response format
+ * (viewtype), and then passes the remaining array to the service handler
+ * function registered by {@link register_service_handler()}.
+ *
+ * If a service handler isn't found, a 404 header is sent.
