hotwatch is a Rust library for conveniently watching and handling file changes.
Nightly Rust is required, since I used the box keyword a few times. Sorry.
```rust use hotwatch::{Hotwatch, Event};
let mut hotwatch = Hotwatch::new().expect("Hotwatch failed to initialize."); hotwatch.watch("war.png", |e: Event| { if let Event::Write(path) = e { println!("War has changed."); } }).expect("Failed to watch file!"); ```
