# Crate of the Week

This is a new part of this weekly installation, where we will write about a crate that some of you may not know.
Please nominate a crate of your choice at the [rust-users thread](https://users.rust-lang.org/t/crate-of-the-week/2704/15) so we can write about it next week.

This week, Crate of the Week is **[clap](https://github.com/kbknapp/clap-rs)**. Thanks go to [eternaleye](https://users.rust-lang.org/users/eternaleye) for the suggestion.

Quoting [eternaleye](https://users.rust-lang.org/users/eternaleye) verbatim:

*I'm going to say kbknapp's [clap](https://github.com/kbknapp/clap-rs) crate - I have never, in _any_ language I have ever worked in, had an argument parsing library that was so completely painless.
I've found it especially nice for mocking up the skeleton of a tool where all roads lead to panic!(), then splitting it up further and further, pushing the panic!()s down the branching logic of what to actually do, until a whole utility has appeared from nowhere.*

# Quote of the Week

On `#rust-offtopic` IRC

> 03:46 < durka42> rust has a culture of small crates
>
> 03:47 < XMPPwocky> a Cargo cult, if you will

Thanks to [Manishearth](https://users.rust-lang.org/users/Manishearth) for the tip. [Submit your quotes for next week!][submit].
