+;;; .dir-locals.el
+;;
+;; If you get ``*** EPC Error ***`` (even after a jedi:install-server) in your
+;; emacs session, mostly you have jedi-mode enabled but the python enviroment is
+;; missed.  The python environment has to be next to the
+;; ``<repo>/.dir-locals.el`` in::
+;;
+;;     ./local/py3
+;;
+;; In Emacs, some buffer locals are referencing the project environment:
+;;
+;; - prj-root                                --> <repo>/
+;; - python-environment-directory            --> <repo>/local
+;; - python-environment-default-root-name    --> py3
+;; - python-shell-virtualenv-root            --> <repo>/local/py3
+;;       When this variable is set with the path of the virtualenv to use,
+;;      `process-environment' and `exec-path' get proper values in order to run
+;;      shells inside the specified virtualenv, example::
+;;         (setq python-shell-virtualenv-root "/path/to/env/")
+;;
+;; To setup such an environment build target 'pyenv' or 'pyenvinstall'::
+;;
+;;   $ make pyenvinstall
+;;
+;; Alternatively create the virtualenv, source it and install jedi + epc
+;; (required by `emacs-jedi <https://tkf.github.io/emacs-jedi>`_)::
+;;
+;;     $ virtualenv --python=python3  "--no-site-packages" ./local/py3
+;;     ...
+;;     $ source ./local/py3/bin/activate
+;;     (py3)$ # now install into the activated 'py3' environment ..
+;;     (py3)$ pip install jedi epc
+;;     ...
+;;
+;; Here is what also I found useful to add to my .emacs::
+;;
+;;     (global-set-key [f6] 'flycheck-mode)
+;;     (add-hook 'python-mode-hook 'my:python-mode-hook)
+;;
+;;     (defun my:python-mode-hook ()
