        The test program couldn't locate one of these files that normally exist:
           #{inn}
           #{conv_bin}
           #{info_bin}
           #{hear_bin}
        We are sorry for the mistake.  Another test you can run on this software
        will occur during install if you add --with-check like this:

      EOS
      oh1 '    brew rm audiofile'
      oh1 '    brew -v install audiofile --with-check'
      return
    end

    mktemp do
      system "#{conv_bin} #{inn} #{out} format wave"
      system "#{info_bin} --short --reporterror #{out}"
      system "#{hear_bin} -p #{out}" if ARGV.verbose?
      puts
      oh1 <<-EOS.undent
        Cheers mate. You converted a system sound from the Audio
        Interchange File Format \"aiff\" to the MS RIFF Wave format.
