-# 1) Run all examples and create example-XXX.out
-# shell> ansible-playbook playbook.yml -e examples_one=true
-#
-# 2) Optionally, for testing, create examples_all.rst
-# shell> ansible-playbook playbook.yml -e examples_all=true
-#
-# 3) Create docs REST files
-# shell> ansible-playbook playbook.yml -e merging_lists_of_dictionaries=true
-#
-# Notes:
-# * Use YAML callback, e.g. set ANSIBLE_STDOUT_CALLBACK=community.general.yaml
-# * Use sphinx-view to render and review the REST files
-#   shell> sphinx-view <path_to_helper>/examples_all.rst
-# * Proofread and copy completed docs *.rst files into the directory rst.
-# * Then delete the *.rst and *.out files from this directory. Do not
-#   add *.rst and *.out in this directory to the version control.
