 // MTaskInteractive

+// If you want to create a new task inside a macro you will have to compile
+// your macro using macro.C++, because the root interpreter cannot use
+// uncompiled classes. To workaround this problem you can write simple
+// funcions (which can be handled by CINT) and use MTaskInteractive.
