+# Script to automate the preparation steps for an L4Sys experiment
+#
+# The L4Sys experiment manual lists four steps that need to be performed
+# in order to launch an L4Sys campaign. This script automates the final
+# three steps.
+#
+# Usage: Follow the manual. Find injection addresses and CR3 value and
+#        adjust experimentInfo.hpp accordingly. Then run this script.
+#
+# TODO: Adjust $FAILDIR to your needs!
