#: * `uses` [`--installed`] [`--recursive`] [`--include-build`] [`--include-optional`] [`--skip-recommended`] [`--devel`|`--HEAD`] <formulae>:
|
|
#: Show the formulae that specify <formulae> as a dependency. When given
|
|
#: 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
|
|
#: or recommended dependency. To include the `:build` type dependencies, pass
|
|
#: `--include-build`. Similarly, pass `--include-optional` to include `:optional`
|
|
#: dependencies. To skip `:recommended` type dependencies, pass `--skip-recommended`.
|

#: By default, `uses` shows usages of <formulae> by stable builds. To find
|
|
#: cases where <formulae> is used by development or HEAD build, pass
