NAME
     acpipmtr -- ACPI Power Meter

SYNOPSIS
     acpipmtr* at acpi?

DESCRIPTION
     The acpipmtr device driver provides support for ``power meters''.	These are sensors that approximate the current power consumption of the
     system.  Alternatively, a power meter may measure also the power gain when the system is connected to an external power supply.

     The available information (namely, the power consumption) is made available through the envsys(4) API and the envstat(8) command.

SEE ALSO
