AutoIt is a freeware Microsoft Windows automation language. It was most commonly used to create automation scripts (sometimes called macros) for Microsoft Windows programs. Like other automation programs, AutoIt is best used for highly repetitive activities, such as rolling out a large number of PCs with identical installation instructions. However, with the new releases it has become an extremely flexible and easy to learn language. While it does lack some features that are commonplace for other languages (such as classes and advanced graphics functions), it is quickly becoming a serious contender for other languages.
