`uses` [<options>] <formula>

Show the formulae that specify <formula> as a dependency. 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.
|
|
|
|
By default, `uses` shows usage of <formula> by stable builds.
