//! fluent-langneg is an API for operating on locales and language tags.
//! It's part of Project Fluent, a localization framework designed to unleash
//! the expressive power of the natural language.
//!
//! The primary use of fluent-langneg is to parse/modify/serialize language tags
//! and to perform language negotiation.
//!
//! It can parse full BCP47 language tags, and will serialize them back,
//! but currently only allows for operations on primary subtags and
//! unicode extension keys.
//!
//! In result fluent-langneg is not suited to replace full implementations of
//! but is arguably a better option for use cases involving operations on
//! language tags and for language negotiation.
