+
+	  Those utilities are required on the target system to start
+	  and stop tracing sessions. Analysis of the trace can be done
+	  on the host machine using the babeltrace utility. This
+	  utility is automatically built by Buildroot in
+	  $(O)/host/usr/bin/babeltrace, as a dependency of
+	  lttng-tools. However, there is also a lttng-babeltrace
+	  package for the target, if babeltrace on the target is
+	  interesting.
