 * # vivi
 *
 * `vivi` is a custom component library for [Slint](https://slint.dev/).
 *
 * ## How to use
 *
 * First of all you have to add slint` as dependency to the `Cargo.toml` file of your project and `vivi` and slint-build` as build
 * dependency.
 *
 * ### Cargo.toml
 *
 * ```toml
 * [package]
 * ...
 * build = "build.rs"
 * edition = "2021"
 *
 * [dependencies]
 * slint = { version = "1.6" }
 * ...
 *
 * [build-dependencies]
 * slint-build = { version = "1.6" }
 * vivi_ui = "0.1.0"
 * ```
 * As next use the API of the slint-build crate in the `build.rs` file and vivi to include the import paths.
 *
 * ### build.rs
 *
 * ```ignore
 * fn main() {
 *   slint_build::compile_with_config(
 *          "ui/index.slint",
 *          slint_build::CompilerConfiguration::new().with_library_paths(vivi_ui::import_paths()),
 *      )
 *      .unwrap();
 * }
 * ```
 *
 * `vivi` can now be used inside of your Slint files:
 *
 * ### index.slint
 *
 * ```slint
 * import { MagicVerticalBox, FilledButton } from "@vivi/magic.slint";
 *
 * export component HelloWorld inherits Window {
 *     MagicVerticalBox {
 *         FilledButton {
 *             text: "Click Me";
 *             clicked => { self.text = "Hello World"; }
 *         }
 *    }
 * }
 * ````
 *
 * Finally, use the [`include_modules!`] macro in your `main.rs`:
 *
 * ### main.rs
 *
 * ```ignore
 * slint::include_modules!();
 * fn main() {
 *     HelloWorld::new().unwrap().run().unwrap();
 * }
 * ```
 *
