The XPL file extension is related to X-Plane, one of the most advanced flight simulators, and used for its plug-in files. A plugin is executable code that runs inside X-Plane, extending what X-Plane does. Plugins are modular, allowing developers to extend the simulator without having to have the source code to the simulator. This chapter describes the basics of what a plugin is, how it works, and describes how we write one.
