#: * `uses` [`--installed`] [`--recursive`] [`--include-build`] [`--include-optional`] [`--skip-recommended`] [`--devel`|`--HEAD`] <formulae>:

#: multiple formula arguments, show the intersection of formulae that use

#: <formulae>.

#: Use `--recursive` to resolve more than one level of dependencies.

#: If `--installed` is passed, only list installed formulae.

#: By default, `uses` shows all formulae that specify <formulae> as a required
