libdevkit-power-gobject-dev 1:0.9.5-3 (i386 binary) in ubuntu maverick

 upower provides an interface to enumerate power sources on the system
 and control system-wide power management. Any application can access the
 org.freedesktop.UPower service on the system message bus. Some
 operations (such as suspending the system) are restricted using PolicyKit.
 .
 This package contains development files for the old version of the shared
 library. It provides the same API as the old DeviceKit-power library, but
 works with upower.
