//! Print score and base score for several vectors.
//!
//! # Description
//!
//! The `base_score()` method allows you to get the base score for [CVSS
//! v2][cvss-v2] and [CVSS v3][cvss-v3] vectors.  For [CVSS v4][cvss-v4]
//! vectors the score returned by `base_score()` is identical to the
//! score returned by `Score::from()`.
//!
//! # Usage
//!
//! ```sh
//! cargo run --example base-score
//! ```
