`cargo ebuild` is a Cargo subcommand that generates an
[ebuild](https://wiki.gentoo.org/wiki/Ebuild) recipe that uses
[cargo.eclass](https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/cargo.eclass)
to build a Cargo based project for [Gentoo](https://gentoo.org/)

## Installation

Install it with Cargo:

```
$ cargo install cargo-ebuild
```

## Usage

You will first need to get the sources to the crate you want to install.
Your best bet is to search for the crate at [crates.io](https://crates.io)
and follow the *Repository* link. This should give you the ability to clone
the repo. Once you have cloned the repo, change into the directory and
ensure that you checkout the tag corresponding to the version you would like
to package. Lastly you will execute the `cargo ebuild` command to generate the
ebuild for that crate.

### Example

```bash
$ git clone https://github.com/cardoe/cargo-ebuild.git
$ cd cargo-ebuild
$ git checkout v0.3.0
$ cargo ebuild
$ cat cargo-ebuild-0.3.0.ebuild
```
