+# To use this script, make sure you have the colcon plugins installed according

+# Source the navstack_dependencies_ws and then cd to the navigation2_ws.

+# Run this script by invoking navigation2/tools/run_sanitizers
+# Afterwards, there should be two files in the root of the workspace:
+#  - sanitizer_report-asan.csv
+#  - sanitizer_report-tsan.csv
