# 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.
