Cargo crate or rustup component

[pickfire]

It would be nice to install rust-cookbook through cargo.

$ cargo install rust-cookbook
$ cargo rust-cookbook

Or maybe as rustup component.

$ rustup component add rust-cookbook
$ rustup doc  # add inside rust doc or some kind of doc auto discovery

I think the cookbook is a good web resource, that happens to have an offline version/development instance. I think most people who use it offline are actually contributors. I'd love to hear otherwise.
