 The simplest way to attach a second sink is via Logger::addWriter(), which promotes the existing writer into a MultiLogWriter automatically:
 <code cpp>
-  Logger::setDefaultStreamLogger(std::cout, "myLog");
+  Logger::setDefaultStreamLogger(std::cout, "/tmp/myLog");
   Logger::addWriter(std::make_shared<SysLogWriter>("myLog"));
   auto log = Logger::getLogger('A');

 <code cpp>
+  #include <eeros/logger/MultiLogWriter.hpp>
   auto multi = std::make_shared<MultiLogWriter>();
-  multi->add(std::make_shared<StreamLogWriter>(std::cout, "myLog"));
+  multi->add(std::make_shared<StreamLogWriter>(std::cout, "/tmp/myLog"));
   multi->add(std::make_shared<SysLogWriter>("myLog"));
   Logger::setDefaultWriter(multi);
