What I'm looking for is a mechanism by which the documentation can
remain in the image even when HelpSystem is absent. So when HelpSystem
is loaded it needs to discover available books. Is there some tag/marker
mechanism by which one can flag those pre-existing books?

That's useful, but I'd still need a way of denoting to HelpSystem, "hey,
here, over here, (*hand waiving*) me, yes, me, I'm a HelpBook!" :-)

It's simply extremely annoying. That's why I was saying, why not derive
help books from class comments? That's is a place for documentation
already, it has all those properties. And for many types of
documentation this is just the right place.

Right I've seen that. This is pretty good already, the only thing I'm
asking for is just a tiny bit of additional structure in a class comment
so that one can have sections etc.

I'd say: All of them! :-) This is a matter of builders, no? I don't
think there's a need to decide upfront that only one format will be
supported. We could start with simple Wiki syntax which can be used in
class comments and other simple places. If people feel unsatisfied or
need more or want to use HelpSystem for other purposes, extend it as
