+         This option optimizes the scheduler for common desktop workloads by
+         automatically creating and populating task groups.  This separation
+         of workloads isolates aggressive CPU burners (like build jobs) from
+         desktop applications.  Task group autogeneration is currently based
+         upon task session.
