#: * `unlinkapps` [`--local`] [`--dry-run`] [<formulae>]:
#: Remove symlinks created by `brew linkapps` from `/Applications` (deprecated).
#:
#: Unfortunately `brew linkapps` cannot behave nicely with e.g. Spotlight using
#: either aliases or symlinks and Homebrew formulae do not build "proper" `.app`
#: bundles that can be relocated. Instead, please consider using `brew cask` and
#: migrate formulae using `.app`s to casks.
#:
#: If no <formulae> are provided, all linked apps will be removed.
#:
#: If provided, `--local` will remove symlinks from the user's `~/Applications`
#: directory instead of the system directory.
#:
#: If `--dry-run` or `-n` is passed, Homebrew will list all symlinks which
#: would be removed, but will not actually delete any files.

`brew unlinkapps` has been deprecated and will eventually be removed!
Unfortunately `brew linkapps` cannot behave nicely with e.g. Spotlight using either aliases or symlinks and Homebrew formulae do not build "proper" `.app` bundles that can be relocated. Instead, please consider using `brew cask` and migrate formulae using `.app`s to casks.
