What is ExtendScript?

ExtendScript is a scripting language and an associated toolkit developed by Adobe Systems, intended for use with Creative Suite and Technical Communication Suite products. It is a dialect of the ECMAScript 3 standard and therefore similar to JavaScript and ActionScript. The toolkit comes bundled with Creative Suite and Technical Communication Suite editions and can access tools within applications like Photoshop, FrameMaker, InDesign or After Effects for batch-processing projects.

Open the Terminal app to run the following commands. If you are unfamiliar with Terminal, you can find it in /Applications/Utilities/Terminal.app.
