/// The Tauri configuration object.
/// It is read from a file where you can define your frontend assets,
/// configure the bundler and define a tray icon.
///
/// The configuration file is generated by the
/// [`tauri init`](https://tauri.app/v1/api/cli#init) command that lives in
/// your Tauri application source directory (src-tauri).
///
/// Once generated, you may modify it at will to customize your Tauri application.
///
/// ## File Formats
///
/// By default, the configuration is defined as a JSON file named `tauri.conf.json`.
///
/// Tauri also supports JSON5 and TOML files via the `config-json5` and `config-toml` Cargo features, respectively.
/// The JSON5 file name must be either `tauri.conf.json` or `tauri.conf.json5`.
/// The TOML file name is `Tauri.toml`.
///
/// ## Platform-Specific Configuration
///
/// In addition to the default configuration file, Tauri can
/// read a platform-specific configuration from `tauri.linux.conf.json`,
/// `tauri.windows.conf.json`, `tauri.macos.conf.json`, `tauri.android.conf.json` and `tauri.ios.conf.json`
/// (or `Tauri.linux.toml`, `Tauri.windows.toml`, `Tauri.macos.toml`, `Tauri.android.toml` and `Tauri.ios.toml` if the `Tauri.toml` format is used),
/// which gets merged with the main configuration object.
///
/// ## Configuration Structure
///
/// The configuration is composed of the following objects:
///
/// - [`app`](#appconfig): The Tauri configuration
/// - [`build`](#buildconfig): The build configuration
/// - [`bundle`](#bundleconfig): The bundle configurations
/// - [`plugins`](#pluginconfig): The plugins configuration
///
/// ```json title="Example tauri.config.json file"
/// {
///   "productName": "tauri-app",
///   "version": "0.1.0"
///   "build": {
///     "beforeBuildCommand": "",
