| <p>Cargo is a single binary composed of a set of <a href="https://clap.rs/"><code>clap</code></a> subcommands. All |
| subcommands live in <a href="https://github.com/rust-lang/cargo/tree/master/src/bin/cargo/commands"><code>src/bin/cargo/commands</code></a> directory. |
| <a href="https://github.com/rust-lang/cargo/blob/master/src/bin/cargo/main.rs"><code>src/bin/cargo/main.rs</code></a> is the entry point.</p> |
| <p>Each subcommand, such as <a href="https://github.com/rust-lang/cargo/tree/master/src/bin/cargo/commands/build.rs"><code>src/bin/cargo/commands/build.rs</code></a>, usually performs |
| the following:</p> |
| <ol> |
| <li>Parse the CLI flags. See the <a href="https://github.com/rust-lang/cargo/blob/master/src/cargo/util/command_prelude.rs"><code>command_prelude</code></a> module for some helpers to make this easier.</li> |
| <li>Load the config files.</li> |
| <li>Discover and load the workspace.</li> |
| <li>Calls the actual implementation of the subcommand which resides in <a href="https://github.com/rust-lang/cargo/tree/master/src/cargo/ops"><code>src/cargo/ops</code></a>.</li> |
| </ol> |
| <p>If the subcommand is not found in the built-in list, then Cargo will |
| automatically search for a subcommand named <code>cargo-{NAME}</code> in the users <code>PATH</code> |
| to execute the subcommand.</p> |
