## Crate of the Week

<!-- COTW goes here -->
This week's crate is [cmd_lib](https://crates.io/crates/cmd_lib), a library of command-line macros and utilities to write shell-script like tasks easily in Rust.

Thanks to [Remo Senekowitsch](https://users.rust-lang.org/t/crate-of-the-week/2704/1382) for the suggestion!

[Please submit your suggestions and votes for next week][submit_crate]!
