Add functionality to TWiki with extensions not based on the TWiki scripts.
An add-on runs separately from the TWiki scripts, e.g. for data import, export to static HTML, etc. Add-Ons normally do not call any TWiki code directly, though may invoke TWiki scripts. There are different types on add-ons, they may be stand alone scripts, browser plugins, office tool extensions, or even a set of TWiki topics that form a TWiki application.
