Xtras for Director

Xtras are tools Macromedia uses to encapsulate functions within Director. They are "plug-in" code modules that let users add specialized capabilities and extended functionality to Macromedia products. In other words, Xtras are extensions to Macromedia products that provide features not built in to the product itself. This brief document describes the technology that supports Xtras, and provides resources for the interested reader seeking further information. [via]
