LTTng and LTTV from Debian and RPM binary packages, the second one explains how
to install LTTng and LTTV from sources and the third one describes the steps
to follow to trace a system and view it. The fourth and last part explains
-briefly how to add a new trace point to the kernel.
+briefly how to add a new trace point to the kernel and to user space
+applications.
+
+What you will typically want is to read sections 2 and 3 : install LTTng from
+sources and use it.
+
+These operations are made for installing the LTTng 0.5.X tracer on a
+linux 2.6.X kernel. You will also find instructions for installation of
+LTTV 0.8.x : the Linux Trace Toolkit Viewer.

-will have to install from sources (section 2) instead.

The following lttng patch is necessary to have the tracing hooks in the kernel.
The following ltt-control module controls the tracing.
