//! 💡  This is a silly little command line tool for sexy fonts in the console. **Give your cli some love.**
//!
//! ---
//! This library supports:
//! - different fonts
//! - multiple colors per font
//! - color gradient
//! - text alignment
//! - letter spacing and line height options
//!
//! ## Usage
//!
//! ```sh
//! $ cfonts "Hello world" --font
//!
//!
//!  ╦ ╦ ╔═╗ ╦   ╦   ╔═╗      ╦ ╦ ╔═╗ ╦═╗ ╦   ╔╦╗
//!  ╠═╣ ║╣  ║   ║   ║ ║      ║║║ ║ ║ ╠╦╝ ║    ║║
//!  ╩ ╩ ╚═╝ ╩═╝ ╩═╝ ╚═╝      ╚╩╝ ╚═╝ ╩╚═ ╩═╝ ═╩╝
//!
//!
//! ```
//!
