+//! # Cargo features
+//!
+//! The following are a list of Cargo features that can be enabled or disabled:
+//!
+//! - **wry** *(enabled by default)*: Enables the [wry](https://github.com/tauri-apps/wry) runtime. Only disable it if you want a custom runtime.
+//! - **menu**: Enables application menus support.
+//! - **reqwest-client**: Uses `reqwest` as HTTP client on the `http` APIs. Improves performance, but increases the bundle size.
+//! - **cli**: Enables usage of `clap` for CLI argument parsing. Enabled by default if the `cli` config is defined on the `tauri.conf.json` file.
+//! - **system-tray**: Enables application system tray API. Enabled by default if the `systemTray` config is defined on the `tauri.conf.json` file.
+//! - **updater**: Enables the application auto updater. Enabled by default if the `updater` config is defined on the `tauri.conf.json` file.
