Right (though I should warn I didn't actually read your directory
structure, Tongu).  An __init__.py is required for packages, and in
order to import stuff from the package, you have to import that stuff
into __init__.

__all__ is just for

from skib import *


which you almost certainly don't (or shouldn't) want anyway.
