      Note that homebrew also provides a compiled macvim Formula that links its
      binary to /usr/local/bin/mvim. And the Cask MacVim also does. It's not
      recommended to install both the Cask MacVim KaoriYa and the Cask MacVim
      and the Formula of MacVim.

      This cask installs symlinks in /usr/local/bin that target to the binary
      MacVim.app/Contents/MacOS/mvim. Below is the list.
        macvim-askpass / mvim / mvimdiff / mview / mvimex /
        gvim / gvimdiff / gview / gvimex

      With --override-system-vim option, you can have more symlinks to use
      macvim-kaoriya instead of the system vim.
        vi / vim / vimdiff / view / vimex
    EOS
