    $ pip3.7 install --upgrade black
    <snip>
    $ python3.7 contrib/grey.py
    Traceback (most recent call last):
      File "contrib/grey.py", line 54, in <module>
        from _version import version as __version__
    ModuleNotFoundError: No module named '_version'
  
  What am I doing wrong?
  
  Also, should we add a shebang and make the file executable?
