Sorry if this sound naive. there has been quite some change in the
java world (it was capable of doing all dependencies for me), so I
thought I was doing something wrong.

So how do people track dependencies needed for python packages ? There
is no test shipped with my current package, so all I can do is `grep
-r import` at the moment.

Thanks again,
