dtpower is useful for monitoring the battery-state of unix laptops.
dtpower is designed to be used as an app in CDE's frontpanel. dtpower calls
"acpi -a" to get the state (power plugged in or not) of the power adapter.
The icon changes according to the state.
Then "acpi -b" is called to set a tooltip with the current load of the battery.
Provides battery,temperature,ac,cpufreq (SpeedStep,Powernow!) control and monitoring.
Proper suspend to disk/ram and standby by shell hooks that are easy to extend.
APM and ACPI machines are supported equally.
For laptops as well as for workstations.
