LTTng-UST, the Linux Trace Toolkit Next Generation Userspace Tracer, is
port of the low-overhead tracing capabilities of the LTTng kernel tracer
to user-space. The library "liblttng-ust" enables tracing of
applications and libraries.

Note: the "liblttng-ust-fork deadlock" fix is an important fix. Anyone
using the liblttng-ust-fork library is encouraged to upgrade.
