+""" This utility can be used to debug and tune the performance of the
+intel_pstate driver. This utility can be used in two ways:
+- If there is Linux trace file with pstate_sample events enabled, then
+this utility can parse the trace file and generate performance plots.
+- If user has not specified a trace file as input via command line parameters,
+then this utility enables and collects trace data for a user specified interval
+and generates performance plots.
+
+Prerequisites:
+    Python version 2.7.x
+    gnuplot 5.0 or higher
+    gnuplot-py 1.8
+    (Most of the distributions have these required packages. They may be called
+     gnuplot-py, phython-gnuplot. )
+
+    HWP (Hardware P-States are disabled)
+    Kernel config for Linux trace is enabled
+
+    see print_help(): for Usage and Output details
