+ Userspace utilities for the LTTng 2.x tracing
+ infrastructure.
+
+ 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.
+
+ If userspace tracing is desired, you need to enable
+ lttng-libust.
