+ *
+ * The log formatter is designed to output to one or multiple formatters at the same time.  For

+ * the file.
+ *
+ * Usage:
+ *
+ *     // Call in init_unit_test_suite: (this will override the --log_format parameter)
+ *     auto formatter = new boost::unit_test::output::multi_log_formatter; // same as already configured logger

+ *     formatter.add(std::make_shared<boost::unit_test::output::xml_log_formatter>(),
+ *                   std::make_shared<std::ofstream>("out.xml"));
+ *
+ *      boost::unit_test::unit_test_log.set_formatter(formatter);
+ *
+ * @note Calling `boost::unit_test::unit_test_log.set_stream(...)` will change the stream for
+ *       the original logger.
