+/* This plugin is designed to measure your battery performance in real-time.
+   It will create a big file, read it every ~90 seconds and log the
+   battery level in /battery.log
+
+   When battery level goes below 5% the plugin exits, to avoid writing to
+   disk in very low battery situations.
+   
+   Note that this test will run for 10-15 hours or more and is very boring
+   to watch.
