"""
The aim of this PEP is to standardize the high-level structure of 
docstrings: what they should contain, and how to say it (without 
touching on any markup syntax within docstrings). The PEP 
contains conventions, not laws or syntax.
"""

you think it means.  Just for the record [1], [2], [3], [4] all 
in my first page of search Google search results.  Pot, meet 
kettle.
