-//! 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                                                       |
-//! |------------------------|-------------------------------------------------------------------|
-//! | `--config-file`        | Config file to read most of the variables from.                   |
-//! | `--current-version`    | Version that needs to be updated.                                 |
-//! | `--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.                               |
-//! | `--new-version`        | New version that should be in the files.                           |
-//! | `--commit`             | Create a commit in version control (default: true).                |

-//! | `--message`            | Commit message (default: Bump version: {current_version} → {new_version}). |
-//! | `file`                 | Files to change.                                                  |
