+      OProfile is a system-wide profiler for Linux systems, capable of
+      profiling all running code at low overhead.  It consists of a
+      kernel driver and a daemon for collecting sample data, and
+      several post-profiling tools for turning data into information.
+
+      OProfile leverages the hardware performance counters of the CPU
+      to enable profiling of a wide variety of interesting statistics,
+      which can also be used for basic time-spent profiling. All code
+      is profiled: hardware and software interrupt handlers, kernel
+      modules, the kernel, shared libraries, and applications.
