Caffeine 1.1.1 for your Mac
Caffeine is a program built to keep your Mac going, much like caffeine does for the common human user with a few added capabilities. Caffeine prevents your Mac from going into sleep mode, making use of a screensaver, hibernating or auto dimming. With a nice coffee cup for an icon all one has to do is fill the cup to activate and empty the cup to allow the Mac some rest.
All computers must be shut down from time to time, please do not abuse the caffeine.
