screensaver and powersaver blocker (like caffeine)
Wakefull, like Caffeine, keeps your screen awake by blocking screen/power savers.
The main difference from Caffeine is that Wakefull gives you (the user) access to the scripts being run - so you can adapt it for whatever environment you are using.
This was developed for a system where Caffeine was not readily available.
