+ * Reading back the file shows you the current setting and the permitted
+ * ranges if changable.
+ *
+ * Writing an integer to the file, change the setting accordingly.

+ * When you have finished the editing, write "c" (commit) to the file to commit
+ * your changes.

+ * If you want to reset to the default value, write "r" (reset) to the file to
+ * reset them.
+ *
+ * This setting works only if the Zero RPM setting is enabled. It adjusts the
