Hmm, nice. So AutoIt is similar to AppleScript in the Mac world.
No, not really. AutoIt doesn't suck.
AppleScript is just about the worst "scripting" tool I've ever used in my life. At the core, it has ass-backwards and completely convoluted syntax.
If an app doesn't have AppleScript support baked in, you're out of luck. If you want to create your own GUI stuff, AppleScript is limited without add-ons.
AutoIt can control and manipulate pretty much any application in various ways, including through direct GUI manipulation if all else fails. It can also create a lot of GUI elements itself.
And if you have any experience with pretty much any other programming language, AutoIt is extremely straight forward.
