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

+
+4. Redistribution. You may reproduce and distribute copies of the
+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or

+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution

+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.

+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.

+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing

+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+
+//! A logger configured via an environment variable which writes to standard
+//! error with nice colored output for log levels.
+//!
+//! ## Example
+//!
+//! ```
+//! extern crate pretty_env_logger;
+//! #[macro_use] extern crate log;
+//!
+//! fn main() {
+//!     pretty_env_logger::init();
+//!
+//!     trace!("a trace example");
+//!     debug!("deboogging");
+//!     info!("such information");
+//!     warn!("o_O");
+//!     error!("boom");
+//! }
+//! ```
+//!
+//! Run the program with the environment variable `RUST_LOG=trace`.
+//!
+//! ## Defaults
+//!
+//! The defaults can be setup by calling `init()` or `try_init()` at the start
+//! of the program.
+//!
+//! ## Enable logging
+//!
+//! This crate uses [env_logger][] internally, so the same ways of enabling
+//! logs through an environment variable are supported.
+//!
+//! [env_logger]: https://docs.rs/env_logger
