A SKETCHUP Extension is like any other Ruby SCRIPT, except for the fact that you make a few extra code calls to tell SketchUp that it's an "extension." When you tell SketchUp that you are loading an extension, you can also tell it COPYRIGHT information, developer information, and a description of the extension. All these DATA are visible to the user inside of SketchUp. Anoher benefit is that users can easily turn extensions on and off without having to fully uninstall and reinstall them. Extensions are a LITTLE more work to code, but they make it easier for end users to manage their SketchUp installation.
