//! # Unreact
//!
//! [Unreact](https://github.com/darccyy/unreact) is a simple static site generation framework
//!
//! ## Quick Start
//!
//! See also: [examples](https://github.com/darccyy/unreact/tree/main/examples)
//! and [unreact template](https://github.com/darccyy/unreact-template)
//!
//! Create an site with a single index page
//!
//! ```
//! use unreact::prelude::*;
//!
//! fn main() -> Result<(), Error> {
//!    // Create the app
//!    // Using default config, not in dev mode, and an example url
//!    let mut app = Unreact::new(Config::default(), false, "https://example.com")?;
//!    // Create an index route
//!    // This uses the template 'page.hbs' in 'templates/'
//!    // A json object with a value for 'foo' is passed into the template
//!    app.index("page", object! { foo: "World!" });
//!    // Compile it!
//!    app.compile()
//! }
//! ```
//!
//! Your workspace should look something like this:
//!
//! ```txt
//! unreact-app/
//!   ├─ Cargo.toml
//!   ├─ src/
//!   │  └─ main.rs
//!   │
//!   ├─ templates/
//!   │  └─ page.hbs
//!   │
//!   ├─ styles/
//!   └─ public/
//! ```
//!
//! This is the contents of `templates/page.hbs`:
//!
//! ```hbs
//! <h1> Hello {{foo}} </h1>
//! ```
//!
//! This will render `build/index.html`:
//!
//! ```html
//! <h1> Hello World! </h1>
//! ```
//!
//! A larger project could look something like this:
//!
//! ```txt
//! unreact-app/
//!   ├─ Cargo.toml
//!   ├─ src/
//!   │  └─ main.rs
//!   │
//!   ├─ templates/
//!   │  ├─ boilerplate.hbs
//!   │  ├─ hello.hbs
//!   │  ├─ other/
//!   │  │  ├─ another/
//!   │  │  │  └─ something.hbs
//!   │  │  └─ article.hbs
//!   │  └─ page.hbs
//!   │
//!   ├─ styles/
//!   │  ├─ global.scss
//!   │  └─ scoped/
//!   │     └─ stylish.scss
//!   │
//!   └─ public/
//!      └─ favicon.ico
//! ```
