// rand = "0.8.3"
// regex = "1.5.4"
//! README
//! ======
//!
//! 1. Install rust if not already installed:
//!
//! ```sh
//! curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh
//! ```
//!
//! 2. Switch to nightly rust:
//!
//! ```sh
//! rustup default nightly
//! ```
//!
//! 3. Install cargo-single:
//!
//! ```sh
//! cargo install cargo-single
//! ```
//!
//! 4. Run the program. The first time you run it may take a while, as it needs to install the
//! program dependencies and compile the program.
//!
//! ```sh
//! cargo single run random_message.rs
//! ```
//!
//! 5. Run again for a different message.
//!
//! ```sh
//! cargo single run random_message.rs
