+/// A callback definition for a hook to be invoked when processes terminate
+///
+/// The parameter is the nullptr if the process is the main driver, for all
+/// child processes, the id string is passed. This allows to customize the
+/// hook depending on the process.
+/// Note that the callback hook is invoked for every process, i.e. main driver
+/// and all childs.
+///
+/// \par Usage:
+/// The customize the hook, add a function with the following signature before
+/// including heder file runDataProcessing.h:
+///
+///     void customize(o2::framework::OnWorkflowTerminationHook& hook)
+///     {
+///       hook = [](const char* idstring){

+///         } else {
+///           std::cout << "child process " << idstring << " terminating" << std::endl;
