Show formulae that specify <formula> as a dependency (i.e. show dependents

|
of <formula>). When given multiple formula arguments, show the intersection
|
|
of formulae that use <formula>. By default, `uses` shows all formulae that
|
|
specify <formula> as a required or recommended dependency for their stable builds.
