(what is does and i/o specs) while comments are for saying how it does it
(the algorithm, which could change without changing the interface).

Docstrings and comments are for the benefit of programmers who use and
revise the code, not for non-programmers ultimate users. I don't see much
difference in this respect between a library function and a specific

I think I personally prefer and find it easier to read docstring material
(as defined above) if it is consistently in docstring format.
