A hook to insert user's config directory into Python's search path.
|
|
|
|
- Ideally that would be in __init__.py (so it's executed without having to import explicityly)
|
|
But, with namespace packages, we can't have __init__.py in the parent subpackage
|
|
(see http://python-notes.curiousefficiency.org/en/latest/python_concepts/import_traps.html#the-init-py-trap)
|
|
|
|
Please let me know if you are aware of a better way of dealing with this!
