+//! # Mime
+//!
+//! Mime is now Media Type, technically, but `Mime` is more immediately
+//! understandable, so the main type here is `Mime`.
+//!
+//! ## What is Mime?
+//!
+//! Example mime string: `text/plain`
+//!
+//! ```
+//! let plain_text: mime::Mime = "text/plain".parse().unwrap();
+//! assert_eq!(plain_text, mime::TEXT_PLAIN);
+//! ```
+//!
+//! ## Inspecting Mimes
+//!
+//! ```
+//! let mime = mime::TEXT_PLAIN;
+//! match (mime.type_(), mime.subtype()) {
+//! (mime::TEXT, mime::PLAIN) => println!("plain text!"),
+//! (mime::TEXT, _) => println!("structured text"),
+//! _ => println!("not text"),
+//! }
+//! ```
