  def caveats
    <<-EOS
      As of mpd-0.17.4, this formula no longer enables support for streaming
      output by default. If you want streaming output, you must now specify
      the --with-libshout, --with-lame, --with-twolame, and/or --with-flac
      options explicitly. (Use '--with-libshout --with-lame --with-flac' for
      the pre-0.17.4 behavior.)

      As of mpd-0.17.4, this formula has renamed options as follows:
        --lastfm            -> --with-lastfm
        --libwrap           -> --with-libwrap (unsupported in OSX >= 10.8)
        --enable-soundcloud -> --with-yajl
    EOS
