    # Why are we specifying HOMEBREW_PREFIX as the prefix?
    #
    # To make vim look for the system vimscript files in the
    # right place, we need to tell it about HOMEBREW_PREFIX.
    # The actual install location will still be in the Cellar.
    #
    # This way, user can create /usr/local/share/vim/vimrc
    # or /usr/local/share/vim/vimfiles and they won't end up
    # in the Cellar, and be removed when vim is upgraded.
