-//! # ⬆️ Bump2version
-//!
-//! Bump2version is a command-line tool for managing version numbers in your projects.
-//! Easily update version strings, create commits, and manage version control tags.

-//! ## Features
-//!
-//! - **Incremental Versioning:** Bump major, minor, or patch versions with ease.
-//! - **Configurability:** Use a configuration file or command-line options to customize behavior.
-//! - **Git Integration:** Create commits and tags in your version control system.
-//!
-//! ## Quick Start
-//!
-//! Get started with the `bump2version` CLI by following these simple steps:
-//!
-//! 1. Install the `bump2version` tool using Cargo:
-//!
-//! ```bash
-//! cargo install bump2version
-//! ```
-//!
-//! 2. Use the following options to manage version numbers and customize the behavior:
-//!
-//! ```bash
-//! bump2version --current-version 1.2.3 --bump patch
-//! ```
-//!
-//! ## Options
-//!
-//! | Option                 | Description                                                       |

-//! | `--bump`               | Part of the version to be bumped (default: patch).                |
-//! | `--parse`              | Regex parsing the version string (default: \d+\.\d+\.\d+).        |
-//! | `--serialize`          | How to format what is parsed back to a version (default: {major}.{minor}.{patch}). |
-//! | `--dry-run`            | Don't write any files, just pretend.                               |
