//! `cabin remove` - remove a dependency from a `cabin.toml` manifest.
//!
//! Deletes a `[dependencies]` (or, with `--dev`, `[dev-dependencies]`)
//! entry by name, leaving the rest of the manifest - comments,
//! ordering, unrelated tables - untouched.  If the table becomes empty
//! it is removed too, matching `cargo remove`.
