//! Gate-Build contains utilities for packing image atlases and other assets
//! as part of the build script for a Gate application (see the "gate" crate).
//!
//! The `AssetPacker` of Gate-Build should be invoked in a build script in a Gate application.
//! Rust enums are generated to reference the packed assets.
//!
//! # Example build script
//!
//! In the below example, the user should place sprite png files in the "sprites" directory,
//! music ogg files in the "music" directory, and sound ogg files in the "sounds" directory.
//!
//! ```rust,no_run
//! extern crate gate_build;
//!
//! use std::path::Path;
//! use std::env;
//! use gate_build::AssetPacker;
//!
//! fn main() {
//! let out_dir = env::var("OUT_DIR").unwrap();
//! let gen_code_path = Path::new(&out_dir).join("asset_id.rs");
//!
//! let mut packer = AssetPacker::new(Path::new("assets"));
//! packer.cargo_rerun_if_changed();
//! packer.sprites(Path::new("sprites"));
//! packer.music(Path::new("music"));
//! packer.sounds(Path::new("sounds"));
//! packer.gen_asset_id_code(&gen_code_path);
//! }
//! ```
