+Nehalem, Sandy Bridge, and Ivy Bridge generations.  Reliable support for newer
+CPUs is not guaranteed, as this package has not seen significant development
+since 2013.
+
+If your processor is supported, you'll get detailed reports on Turbo Boost and
+clock multipliers, core voltage, and time spent in different C-states.  This
+information can be viewed in real time and/or logged to a file.")
