Rework internal errors. This changes the behavior of "internal" errors, which were previously hidden and only displayed with `--verbose`. The changes here: - `internal` now means "a cargo bug", and is always displayed and requests that the user file a bug report. - Added `VerboseError` to signify an error that should only be displayed with `--verbose`. This is only used in one place, to display the `rustc` compiler command if the compiler exited with a normal error code (i.e. not a crash). - Audited the uses of internal errors, and promoted some to normal errors, as they seemed to contain useful information, but weren't necessarily bugs in cargo. - Added some details to some errors. - Sometimes the "run with --verbose" message wasn't being printed when I think it should. This happened when rustc failed while other rustc processes were running. Another case was with `cargo install` installing multiple packages, and one of them fails.
Cargo
Cargo downloads your Rust project’s dependencies and compiles your project.

Code Status
Code documentation: https://docs.rs/cargo/
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:
gitcurl(on Unix)pkg-config(on Unix, used to figure out thelibsslheaders/libraries)- OpenSSL headers (only for Unix, this is the
libssl-devpackage on ubuntu) cargoandrustc
First, you'll want to check out this repository
git clone 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
Cargo releases coincide with Rust releases. High level release notes are available as part of Rust's release notes. Detailed release notes are available in this repo at CHANGELOG.md.
