What is xfce4-power-manager?
============================

This software is a power manager for the Xfce desktop, Xfce power
manager manages the power sources on the computer and the devices that
can be controlled to reduce their power consumption (such as LCD
brightness level, monitor sleep). In addition, xfce4-power-manager
provides a set of freedesktop-compliant DBus interfaces to inform other
applications about current power level so that they can adjust their
power consumption, and it provides the inhibit interface which allows
applications to prevent automatic sleep actions via the power manager;
as an example, the operating system’s package manager should make use of
this interface while it is performing update operations.
