This commit implements a new unstable feature for manifests which allows
renaming a crate when depending on it. For example you can do:
```toml
cargo-features = ["dependencies-as"]
...
[dependencies]
foo = "0.1"
bar = { version = "0.1", registry = "custom", package = "foo" }
baz = { git = "https://github.com/foo/bar", package = "foo" }
```
Here three crates will be imported but they'll be made available to the Rust
source code via the names `foo` (crates.io), `bar` (the custom registry), and
`baz` (the git dependency). The *package* name, however, will be `foo` for all
of them. In other words the git repository here would be searched for a crate
called `foo`. For example:
```rust
extern crate foo; // crates.io
extern crate bar; // registry `custom`
extern crate baz; // git repository
```
The intention here is to enable a few use cases:
* Enable depending on the same named crate from different registries
* Allow depending on multiple versions of a crate from one registry
* Removing the need for `extern crate foo as bar` syntactically in Rust source
Currently I don't think we're ready to stabilize this so it's just a nightly
feature, but I'm hoping we can continue to iterate on it!

Cargo
Cargo downloads your Rust project’s dependencies and compiles your project.
Learn more at https://doc.rust-lang.org/cargo/
Code Status
Installing Cargo
Cargo is distributed by default with Rust, so if you've got rustc installed
locally you probably also have cargo installed locally.
Compiling from Source
Cargo requires the following tools and packages to build:
pythoncurl(on Unix)cmake- OpenSSL headers (only for Unix, this is the
libssl-devpackage on ubuntu) cargoandrustc
First, you'll want to check out this repository
git clone --recursive https://github.com/rust-lang/cargo
cd cargo
With cargo already installed, you can simply run:
cargo build --release
Adding new subcommands to Cargo
Cargo is designed to be extensible with new subcommands without having to modify Cargo itself. See the Wiki page for more details and a list of known community-developed subcommands.
Releases
High level release notes are available as part of Rust's release notes. Cargo releases coincide with Rust releases.
