error-chain makes it easy to take full advantage of Rust's error
handling features without the overhead of maintaining boilerplate
error types and conversions. It implements an opinionated strategy for
defining your own error types, as well as conversions from others'
error types.
If you just want to set up your new project with error-chain, follow the quickstart.rs template, and read this intro to error-chain.
