+//! ```rust
+//! extern crate unicode_security;
+//!
+//! use unicode_security::GeneralSecurityProfile;
+//!
+//! fn main() {
+//!     let ch = 'µ'; // U+00B5 MICRO SIGN
+//!     let allowed = 'µ'.identifier_allowed();
+//!     println!("{}", ch);
+//!     println!("The above char is {} in unicode identifiers.",

+//!
+//! # features
+//!
+//! unicode-security supports a `no_std` feature. This eliminates dependence
+//! on std, and instead uses equivalent functions from core.
+//!
+//! # crates.io
+//!
+//! You can use this package in your project by adding the following
+//! to your `Cargo.toml`:
+//!
+//! ```toml
+//! [dependencies]
+//! unicode-security = "0.0.1"
+//! ```
