"""Displays CPU utilization across all CPUs.

By default, opens `gnome-system-monitor` on left mouse click.

Requirements:
    * the psutil Python module for the first three items from the list above
    * gnome-system-monitor for default mouse click action

Parameters:
    * cpu.warning : Warning threshold in % of CPU usage (defaults to 70%)
    * cpu.critical: Critical threshold in % of CPU usage (defaults to 80%)
    * cpu.format  : Format string (defaults to '{:.01f}%')
