//! A source string with a `node_modules/.bin/<name>` path runs or locates an
//! installed binary. The package that declares the binary is in use, so the
//! dependency is not unused. Fallow maps the binary name to a package with
//! the same map that the script analysis uses. A name that maps to no
//! declared dependency credits nothing and reports nothing.
