 ==== SETTING UP LTTng 2.x ====
 LTTng 2.x features a unified trace-control client "lttng" to control both kernel tracing (through lttng-modules) and userspace tracing (through UST). The client itself is shipped in the "lttng-tools" package.
 To install the toolchain:
 $ sudo apt-add-repository ppa:lttng/ppa
 $ sudo apt-get update
 $ sudo apt-get install lttng-tools lttng-modules-dkms babeltrace
 Once the modules are installed correctly, you can start tracing right away. No need to reboot!
 Note: lttng-tools will pull liblttng-ust0 as a dependency, so you can trace already-instrumented applications right away. If you want to compile an instrumented application, you also need to install the liblttng-ust-dev package, which contains the required include headers.
 You can now refer to http://lttng.org/quickstart to use the kernel or userspace tracers.
 ==== Daily build packages ====
 If you prefer living on the edge, you can use the latest development versions in the daily PPA: https://launchpad.net/~lttng/+archive/daily
