Power Manager supports the open source notification utility, Growl. Growl lets you customise how and when you see notifications from your favourite applications.
Not all applications support Growl. Those that do offer an impressive degree of control over how they can notify you.

Power Manager includes Growl support.
Power Manager comes with Growl support built-in. If you have Growl installed, Power Manager will make use of it. Growl notifications will automatically appear when an event is pending and when an event starts performing.
Let’s use Growl to build upon the recipe for displaying a message after a long running task on your Mac.
