== FILES

`~/.cargo/`::
    Default location for Cargo's "home" directory where it stores various
    files. The location can be changed with the `CARGO_HOME` environment
    variable.

`$CARGO_HOME/bin/`::
    Binaries installed by man:cargo-install[1] will be located here. If using
    rustup, executables distributed with Rust are also located here.

`$CARGO_HOME/config`::
    The global configuration file. See linkcargo:reference/config.html[the reference]
    for more information about configuration files.

`.cargo/config`::
    Cargo automatically searches for a file named `.cargo/config` in the
    current directory, and all parent directories. These configuration files
    will be merged with the global configuration file.

`$CARGO_HOME/credentials`::
    Private authentication information for logging in to a registry.

`$CARGO_HOME/registry/`::
    This directory contains cached downloads of the registry index and any
    downloaded dependencies.

`$CARGO_HOME/git/`::
    This directory contains cached downloads of git dependencies.

== EXAMPLES

. Build a local package and all of its dependencies:

    cargo build

. Build a package with optimizations:

    cargo build --release

. Run tests for a cross-compiled target:

    cargo test --target i686-unknown-linux-gnu

. Create a new package that builds an executable:

    cargo new foobar

. Create a package in the current directory:

    mkdir foo && cd foo
    cargo init .

. Learn about a command's options and usage:

    cargo help clean
