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;
let mut hotwatch = Hotwatch::new().expect("Hotwatch failed to initialize."); hotwatch.watch("war.png", |e: hotwatch::Event| { if e.changed() { println!("War has changed."); } }).expect("Failed to watch file!"); ```
