Could be. I'll have a look at it -- thanks for the link. In general,
however, I would suggest that a website-based multi-page manual is
always a bad idea, for two reasons: First, because it's not searchable.
Second, because it's an invitation to the author to jumble things up
and leave some pages blank "to be filled in later." This is not a
criticism of Kreidler's work, which I haven't read, it's just a general
observation based on other things I've seen.
To give you a second opinion: Kreidler's work is brilliant to me. It's a book which has been printed (german) as well as put on the web (both german and an english translation). I started reading the flossmanual but soon discovered "Loadbang" what the book is called. It helped me a lot.
