That's bad, I think.

I've not much experience with the former. Regarding the latter -- I don't
think I've used tutorial. Requirements for derived type (for iterator_facade)

I'm not sure about this. I always though that V2 tutorial just can contain
enough information to be used on a daily basis.

Probably, but I still find it important to outline few important features in
tutorial, where new users can easily find it. If, say, usage-requirements are
documented deep in user manual, few users will find them.

I can compare this to Boost libraries which have Boostbook + doxygen docs.
Boostbook parts cover higher level things. doxygen parts have docs for each
method of every class. If you try to merge it together, the result will be
unusable. We need to somehow separate commonly needed information from rarely
