- * 0 of the input file always contains only ogg packet #0 while page 1 usually
- * contains both packets 1 (comments) and 2 (setup).  However, we always create

- * versions which causes too little data being copied to the second ogg page.
- * This affects at least Ubuntu Hardy, and there is no real disadvantage in
