This crate is not stable, yet. However, if you do want stability, you should specify the revision (commit hash) in your `Cargo.toml`, this way builds are complete reproducible, and won't break.
For a more complete example, see [a minesweeper implementation](https://github.com/redox-os/games-for-redox/blob/master/src/minesweeper.rs), that I made for Redox using termion.
