The root class is enough.
A subclasses should just say something like 'i am special for
___that__ and do things differently because i want __that__'.

This knowledge is important. It of course a question where to put that,
but that's exactly why i didn't wanted to use autoconf to generate
config.h file, which contains like 50 various flags,
without any clues, where these flags being used, and in what
situations they should be turned on or off..
So, later we could step over every flag and properly document them,
and like that, for people who will come later, we will have an idea
what are need to deal with and why.
