-# For example: use `ynh_pip install` instead of `pip install`
-#
-# With `sudo` or `ynh_exec_as`, use instead the fallback variables `$ynh_pip` and `$ynh_python`
-# And propagate $PATH to sudo with $ynh_python_load_path

-#
-# $PATH contains the path of the requested version of Python.
-# However, $PATH is duplicated into $python_path to outlast any manipulation of $PATH
-# You can use the variable `$ynh_python_load_path` to quickly load your Python version
-#  in $PATH for an usage into a separate script.
-# Exemple: $ynh_python_load_path $final_path/script_that_use_pip.sh`
-#
-#
-# Finally, to start a Python service with the correct version, 2 solutions
-#  Either the app is dependent of python or pip, but does not called it directly.
-#  In such situation, you need to load PATH
