zsh-completions

To activate these completions, add the following to your .zshrc:

  if type brew &>/dev/null; then
    FPATH=$(brew --prefix)/share/zsh-completions:$FPATH

    autoload -Uz compinit
    compinit
  fi

You may also need to force rebuild `zcompdump`:

  rm -f ~/.zcompdump; compinit

Additionally, if you receive "zsh compinit: insecure directories" warnings when attempting
to load these completions, you may need to run these commands:

  chmod go-w '$HOMEBREW_PREFIX/share'
  chmod -R go-w '$HOMEBREW_PREFIX/share/zsh'
