How to structure celery tasks

Based on celery documentation you can import a structure of celery tasks like this:

For example if you have an (imagined) directory tree like this:

|
|-- foo
|    |-- __init__.py
|    |-- tasks.py
|
|-- bar
     |-- __init__.py
     |-- tasks.py

Then calling app.autodiscover_tasks(['foo', bar']) will result in the modules foo.tasks and bar.tasks being imported.
