#: * `uses` [`--installed`] [`--recursive`] [`--include-build`] [`--include-test`] [`--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`, to include the `:test` type dependencies, pass
|

#: `--include-optional`. To skip `:recommended` type dependencies, pass
|
|
#: `--skip-recommended`.

#: By default, `uses` shows usage of <formulae> by stable builds. To find
