#: * `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.
