+This tool is designed to measure and aggregate a few key performance metrics
+for all Chrome processes over time. The tool supports other browsers such as
+Edge or Firefox, or in fact any other processes. The inclusion of processes
+is based on a simple partial process image name match against the image name
+argument (optional, Chrome.exe is the default image name used when no
+argument is provided).
+
+Sample usage:
+
+"IdleWakeups.exe" to match all Chrome.exe processes.
+"IdleWakeups.exe" firefox to match Firefox process.
+"IdleWakeups.exe MicrosoftEdge" to match all Edge processes.
+
+When the tool starts it begins gathering and aggregating CPU usage, private
+working set size, number of context switches / sec, and power usage for all
+matched processes. Hit Ctrl+C to stop the measurements and print average and
+median values over the entire measurement interval.
+
+CPU usage is normalized to one CPU core with 100% meaning one CPU core is
+fully utilized.
+
+Intel Power Gadget is required to allow IdleWakeups tool to query power usage.
