// TODO:
// * Make this project into an application that starts automatically to test GUI and sound after building the Builder build system.
// * Let the user browse a file system and select a location for a new or existing project.
// * Explain how everything works when starting for the first time, using a command line argument.
// * A catalogue of SDK examples with images and descriptions loaded automatically from their folder.
//     * Offer one-click build and execution of SDK examples on multiple platforms, while explaining how the building works.
