+//! 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));

+// Changes in lang-item visibility injected failures that were only
+// exposed when compiling with `-C prefer-dynamic`. But `rustdoc` used
+// `-C prefer-dynamic` (and had done so for years, for reasons we did
+// not document at that time).
+//
+// Rather than try to revise the visbility semanics, we instead
+// decided to change `rustdoc` to behave more like the compiler's
+// default setting, by leaving off `-C prefer-dynamic`.
