+fatrace reports file access events from all running processes.
+Its main purpose is to find processes which keep waking up the disk
+unnecessarily and thus prevent some power saving.
+
+Included is a python3 script called "power-usage-report", which uses
+fatrace and powertop to build a textual report from one minute of
+measuring power usage and file accesses. This does not take any
+arguments or requires any interactivity, so is very simple to use and
+serves as a starting point for bug reports or optimizing a particular
+installation.
