Avoid, has bad code. Will cause low level damage. Not compatible with recent builds of OSX Tiger. Disabled my Audio so I had to do an archive and backup reinstall on my MBP to fix it. Not surprising that development has stopped on this dangerous program.

What does this do that OS X power management doesn't do already?

It does a lot more but the prefpanel doesn't seem to be included so you have to use the command line. I'm guessing that this isn't submitted by the developer because it's not ready yet.
