Just testing how CI works with this. I tend to prefer vendoring, as it
means that if you have a copy of the code *you can always build it*.
Even if you're 20 years in the future

This is the output of

```
cargo vendor --versioned-dirs

+//! Generic implementation of Hash-based Message Authentication Code (HMAC).
+//!
+//! To use it you'll need a cryptographic hash function implementation from
+//! RustCrypto project. You can either import specific crate (e.g. `sha2`), or
+//! meta-crate `crypto-hashes` which reexport all related crates.
+//!
+//! # Usage
+//! Let us demonstrate how to use HMAC using SHA256 as an example.
+//!
+//! To get the authentication code:
+//!
+//! ```rust
+//! use sha2::Sha256;
+//! use hmac::{Hmac, Mac, NewMac};
+//!
+//! // Create alias for HMAC-SHA256
+//! type HmacSha256 = Hmac<Sha256>;
+//!
+//! // Create HMAC-SHA256 instance which implements `Mac` trait
+//! let mut mac = HmacSha256::new_varkey(b"my secret and secure key")
+//!     .expect("HMAC can take key of any size");
+//! mac.update(b"input message");
+//!
+//! // `result` has type `Output` which is a thin wrapper around array of
+//! // bytes for providing constant time equality check
+//! let result = mac.finalize();
+//! // To get underlying array use `into_bytes` method, but be careful, since
+//! // incorrect use of the code value may permit timing attacks which defeat
+//! // the security provided by the `Output`
+//! let code_bytes = result.into_bytes();
+//! ```
+//!
+//! To verify the message:
+//!
+//! ```rust
+//! # use sha2::Sha256;
+//! # use hmac::{Hmac, Mac, NewMac};
+//! # type HmacSha256 = Hmac<Sha256>;
+//! let mut mac = HmacSha256::new_varkey(b"my secret and secure key")
+//!     .expect("HMAC can take key of any size");
+//!
+//! mac.update(b"input message");
+//!
+//! # let code_bytes = mac.clone().finalize().into_bytes();
+//! // `verify` will return `Ok(())` if code is correct, `Err(MacError)` otherwise
+//! mac.verify(&code_bytes).unwrap();
+//! ```
+//!
+//! # Block and input sizes
+//! Usually it is assumed that block size is larger than output size, due to the
+//! generic nature of the implementation this edge case must be handled as well
+//! to remove potential panic scenario. This is done by truncating hash output
+//! to the hash block size if needed.
