//! # Apple Bundle Resources
//!
//! Resources located in an app, framework, or plugin bundle.
//!
//! A bundle is a directory with a standardized hierarchical structure that holds
//! executable code and the resources used by that code. The bundle contains resources
//! that may be accessed at runtime, such as images, audio files, user interface files,
//! and property lists.
//!
