-//! console is a library for Rust that provides access to various terminal
-//! features so you can build nicer looking command line interfaces. It
-//! comes with various tools and utilities for working with Terminals and
-//! formatting text.
-//!
-//! Best paired with other libraries in the family:
-//!
-//! * [dialoguer](https://docs.rs/dialoguer)
-//! * [indicatif](https://docs.rs/indicatif)
-//!
-//! # Terminal Access
-//!
-//! The terminal is abstracted through the `console::Term` type. It can
-//! either directly provide access to the connected terminal or by buffering
-//! up commands. A buffered terminal will however not be completely buffered
-//! on windows where cursor movements are currently directly passed through.
-//!
-//! Example usage:
-//!
-//! ```
-//! # fn test() -> Result<(), Box<dyn std::error::Error>> {
-//! use std::thread;
-//! use std::time::Duration;
-//!
-//! use console::Term;
-//!
-//! let term = Term::stdout();
-//! term.write_line("Hello World!")?;
-//! thread::sleep(Duration::from_millis(2000));
-//! term.clear_line()?;
-//! # Ok(()) } test().unwrap();
-//! ```
-//!
-//! # Colors and Styles
-//!
-//! `console` automaticaly detects when to use colors based on the tty flag. It also
-//! provides higher level wrappers for styling text and other things that can be
-//! displayed with the `style` function and utility types.
-//!
-//! Example usage:
-//!
-//! ```
-//! use console::style;
-//!
-//! println!("This is {} neat", style("quite").cyan());
-//! ```
-//!
-//! You can also store styles and apply them to text later:
-//!
-//! ```
-//! use console::Style;
-//!
-//! let cyan = Style::new().cyan();
-//! println!("This is {} neat", cyan.apply_to("quite"));
-//! ```
-//!
-//! # Working with ANSI Codes
-//!
-//! The crate provids the function `strip_ansi_codes` to remove ANSI codes
-//! from a string as well as `measure_text_width` to calculate the width of a
-//! string as it would be displayed by the terminal. Both of those together
-//! are useful for more complex formatting.
-//!
-//! # Unicode Width Support
-//!
-//! By default this crate depends on the `unicode-width` crate to calculate
-//! the width of terminal characters. If you do not need this you can disable
-//! the `unicode-width` feature which will cut down on dependencies.
-//!
-//! # Features
-//!
-//! By default all features are enabled. The following features exist:
-//!
-//! * `unicode-width`: adds support for unicode width calculations
-//! * `ansi-parsing`: adds support for parsing ansi codes (this adds support
-//! for stripping and taking ansi escape codes into account for length
-//! calculations).
