-//! This crate exports a macro `enum_from_primitive!` that wraps an
-//! `enum` declaration and automatically adds an implementation of
-//! `num::FromPrimitive` (reexported here), to allow conversion from
-//! primitive integers to the enum. It therefore provides an
-//! alternative to the built-in `#[derive(FromPrimitive)]`, which
-//! requires the unstable `std::num::FromPrimitive` and is disabled in
-//! Rust 1.0.
-//!
-//! # Example
-//!
-//! ```
-//! #[macro_use] extern crate enum_primitive;
-//! extern crate num_traits;
-//! use num_traits::FromPrimitive;
-//!
-//! enum_from_primitive! {
-//! #[derive(Debug, PartialEq)]
-//! enum FooBar {
-//!     Foo = 17,
-//!     Bar = 42,
-//!     Baz,
-//! }
-//! }
-//!
-//! fn main() {
-//!     assert_eq!(FooBar::from_i32(17), Some(FooBar::Foo));
-//!     assert_eq!(FooBar::from_i32(42), Some(FooBar::Bar));
-//!     assert_eq!(FooBar::from_i32(43), Some(FooBar::Baz));
-//!     assert_eq!(FooBar::from_i32(91), None);
-//! }
-//! ```
