  def caveats; <<-EOS.undent
      Weechat can depend on Aspell if you choose the --with-aspell option, but
      Aspell should be installed manually before installing Weechat so that
      you can choose the dictionaries you want.  If Aspell was installed
      automatically as part of weechat, there won't be any dictionaries.
