The package provides the means to insert OGC (Optional Group Content, commonly known as layers) into PDF presentations. This allows the user to insert any TeX material into separate layers in a PDF document and also insert links which toggle these layers on and off. Parts of the PDF document, such as formatted text, tables, maths formulas or graphics may be switched to visible or invisible state by clicking active links or buttons.
The documentation discusses the package’s relation to various apparently similar packages.
