#:  * `prune` [`--dry-run`]:
#:    Remove dead symlinks from the Homebrew prefix. This is generally not
#:    needed, but can be useful when doing DIY installations. Also remove broken
#:    app symlinks from `/Applications` and `~/Applications` that were previously
#:    created by `brew linkapps`.
#:
#:    If `--dry-run` or `-n` is passed, show what would be removed, but do not
#:    actually remove anything.
