  +//! # FlatBuffers
  +//!
  +//! A library for memory-efficient serialization of data.
  +//!
  +//! This crate provides runtime support for the FlatBuffers format in the Rust programming language.
  +//! To use this crate, first generate code with the `flatc` compiler, as described here: https://google.github.io/flatbuffers/
  +//! Then, include that code into your project.
  +//! Finally, add this crate to your `Cargo.toml`.
  +//!
  +//! At this time, Rust support is experimental, and APIs may change between minor versions.
  +//!
  +//! At this time, to generate Rust code, you will need the latest `master` version of `flatc`, available from here: https://github.com/google/flatbuffers
  +//! (On OSX, you can install FlatBuffers from `HEAD` with the Homebrew package manager.)
