+# Plugin to monitor fan speed on an IBM/Lenovo Laptop
+#
+# This plugin reads the current speed of the system fan from
+# the /proc file system. As it queries specific files provided
+# by kernel modules for IBM/Lenovo Laptops, it probably only 
+# works for those, but it should be easy to adapt to others
+# if similar information is available for other types of laptops.
