# 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!
