Greetings everyone (including LTTng elves),

The lttng-tools project provides a session daemon (lttng-sessiond) that
acts as a tracing registry, the "lttng" command line for tracing
control, a lttng-ctl library for tracing control and a lttng-relayd for
network streaming.

Here is the change log for the release candidate 5. Massive amount of fixes for
the live tracing feature so this version should be much more stable with live
streaming.
