[Richard Hughes <hughsient gmail com>]

GNOME Power Manager has branched for 2-16, and all ongoing development
work will be done on HEAD.

Plans for HEAD:

 * CPU frequency scaling.
 * Better preferences application.
 * Integrate g-p-m with more software, e.g. nautilus.
 * Put the graphing stuff out of process.
 * Control more parameters for UPS devices.
 * Give user a choice to abort all actions.
 * Reduce memory usage and processor load.
 * Easier to translate strings

*Lots* of exciting things to come.
