############################################################################

This tool allows to adjust a few consumption relevant settings of your
H3 device. Use the following switches

-h|-H           displays help or verbose help text
-p              print currently active settings
-g on|off       disables GPU/HDMI for headless use
-m max_cpufreq  adjusts maximum allowed cpu clockspeed (mhz)
-c 1|2|3|4      activate only this count of CPU cores
-d dram_freq    adjusts dram clockspeed (408 - 624 mhz)
-D dram_freq    like -d but as low as 132 mhz possible (experimental!)
-u on|off       enables/disabled all USB ports
-e on|off|fast  enables/disables Ethernet, the fast switch
forces 100 mbits/sec negotiation on gigabit devices
-w on|off       enables/disables Wi-Fi powermanagement when interface
