Issue:
Sphinx warning: deprecated app.info
With Sphinx v1.8.1, I get these warnings:

> [automodsumm] tools.rst: found 16 automodsumm entries to generate
/home/simon/.pyenv/versions/3.7.0/lib/python3.7/site-packages/sphinx/application.py:402: RemovedInSphinx20Warning: app.info() is now deprecated. Use sphinx.util.logging instead.
  RemovedInSphinx20Warning)

Probably because of this :
