There were several missing already in previous chapters. In chapter 7 for instance, you do not provide - "music_data.txt" - so the online example of music_browser.cgi cannot be tried out.

Another one is in Chapter 6. I need "rgb.txt" to get the xcolors.cgi to work. You did not provide it.

I find this frustrating - particularly since I paid $35 for the book. And I'm not getting the full benefit of the book.
