// Usage
// 1. Add rusty-binder and rusty-cheddar as build dependencies to your top level Cargo.toml
//   [build-dependencies]
//   rusty-binder = { git = "https://gitlab.com/rusty-binder/rusty-binder.git" }
//   rusty-cheddar = { git = "https://gitlab.com/rusty-binder/rusty-cheddar.git" }
// 2. Set your crate type to static in Cargo.toml
