#![cfg_attr(all(test, feature = "unstable"), feature(test))]

//! A library to read and write ID3v2 tags. ID3 versions v2.2, v2.3, and v2.4 are supported.
//!
//! # Modifying an existing tag
//!
//! ```no_run
//! use id3::{Tag, Version};
//!
//! let mut tag = Tag::read_from_path("music.mp3").unwrap();
//!
//! // print the artist the hard way
//! println!("{}", tag.get("TPE1").unwrap().content().text().unwrap());
//!
//! // or print it the easy way
//! println!("{}", tag.artist().unwrap());
//!
//! tag.write_to_path("music.mp3", Version::Id3v24).unwrap();
//! ```
//!
//! # Creating a new tag
//!
//! ```no_run
//! use id3::{Tag, Frame, Version};
//! use id3::frame::Content;
//!
//! let mut tag = Tag::new();
//!
//! // set the album the hard way
//! let frame = Frame::with_content("TALB", Content::Text("album".to_string()));
//! tag.add_frame(frame);
//!
//! // or set it the easy way
//! tag.set_album("album");
//!
//! tag.write_to_path("music.mp3", Version::Id3v24).unwrap();
//! ```
