## ❄ (Not So) Frequently Asked Questions
1) > When is Barentsz particularly useful?
_When e.g. adding a class to some package and you want it to be picked up
in your application, without having to add an import or registration
somewhere._
2) > Does Barentsz require my classes to be compromised (e.g. with inheritance or a decorator or something)?
_No, never._
3) > What must I do for Barentsz to discover my class (or function, attribute, etc.)?
_Nothing special. Just make sure that the path that is explored is a Python package._
4) > Why do the "Help documentation" sections contain this "\<BLANKLINE\>"?
_That's because this documentation is under [doctest](https://docs.python.org/3/library/doctest.html).
It helps to ensure that the documentation is always up to date._
5) > What's with the funny name?
_Well... since this library is all about exploring and discovering and because
I really enjoyed the cold north, I thought it to be a fitting name._
6) > What is the answer to the Ultimate Question of Life, the Universe, and Everything?
_Haven't got a clue, what are you asking me for anyway? I suggest you build an AI
to deduce the answer (using barentsz of course)._
