OLPC XO power management support daemon
The powerd daemon can function as an easily customizable replacement for ohmd (independent of X, D-Bus, and hald). This package provides the powerd and olpc-switchd daemons, and related utilities. The olpc-switchd daemon simply provides notifications about lid and switch events. The powerd daemon controls display dimming, automatically putting an XO to sleep after a period of idleness, etc.
