liblttng-ust0 - 2.12.1-1 main

The userspace tracer is designed to provide detailed information about
userspace activity. Like the kernel tracer, performance is the main goal.
Tracing does not require system calls or traps. UST instrumentation points may
be added in any userspace code including signal handlers and libraries.
.
This package contains the actual userspace tracing library that must be linked
to the instrumented programs.
