Well, there's a link to quite an old presentation I wrote here
http://people.freedesktop.org/~hughsient/public/gnome-power-manager.pdf
which mentions how pm-utils fits into the stack, although the document
needs updating with the latest PolicyKit and ConsoleKit coolness.

I've also attached the pm-utils README file from CVS which might help.

I agree, this stuff needs better documenting - a wiki page might be
best, or maybe just manpages for the other tools.

Richard.
