//! An end-to-end example of using the SP1 SDK to generate a proof of a program that can be executed
//! or have a core proof generated.
//!
//! You can run this script using the following command:
//! ```shell
//! RUST_LOG=info cargo run --release -- --execute
//! ```
//! or
//! ```shell
//! RUST_LOG=info cargo run --release -- --prove
//! ```
