"""Multiwidget CPU module
Can display any combination of:
* max CPU frequency
* total CPU load in percents (integer value)
* per-core CPU load as graph - either mono or colored
* CPU temperature (in Celsius degrees)
* CPU fan speed
Requirements:
* the psutil Python module for the first three items from the list above
* sensors executable for the rest
Parameters:
* cpu2.layout: Space-separated list of widgets to add.
Possible widgets are:
* cpu2.maxfreq
* cpu2.cpuload
* cpu2.coresload
* cpu2.temp
* cpu2.fanspeed
* cpu2.colored: 1 for colored per core load graph, 0 for mono (default)
if this is set to 1, use --markup=pango
* cpu2.temp_pattern: pattern to look for in the output of 'sensors -u';
required if cpu2.temp widged is used
* cpu2.fan_pattern: pattern to look for in the output of 'sensors -u';
required if cpu2.fanspeed widged is used
Note: if you are getting 'n/a' for CPU temperature / fan speed, then you're
lacking the aforementioned pattern settings or they have wrong values.
