+""" Simple config/run script for the HelloObject
+
+This is probably the simplest gem5 config file you can possibly create.
+It creates a Root object and one *very* simple SimObject and simulates the
+system. Since there are no events, this "simulation" should finish immediately

+# set up the root SimObject and start the simulation
