You can easily automate tasks such as renaming a large group of files, resizing dozens of images to fit an iPhoto slideshow or creating iCal birthday events using Address Book contacts, then repeat those tasks again and again. Simple and easy-to-understand application Actions are the building blocks, so you don't have to write any code. Each Action has all of the options and settings you need. You don't have to work hard to figure out how to make it work.
