GNOME Power Manager is a GNOME session daemon that acts as a policy agent
on top of HAL (the Hardware Abstraction Layer). GNOME Power Manager listens
for HAL events and responds with user-configurable reactions.
Currently it supports laptop batteries and AC adapters. Its goal is to be
architecture neutral and free of polling and other hacks.
