modules)

----------------------------+----------------------------
Python 3 accepts only absolute imports and explicit relative imports.
To be Python 2 compatible all affected modules need {{{from __future__
import absolute_import}}}.
{{{lib2to3/fixes/fix_import.py}}} does not add this __future__
import.[[br]]
Therefore we intend to use an enhanced fixer from
{{{https://pypi.python.org/pypi/future/0.11.3}}}.[[br]]
The latest development version also handles imports of pyx modules.
Changes according to {{{libfuturize/fixes/fix_absolute_imports.py}}}:
{{{
If spam is being imported from the local directory, this import:
from spam import eggs
becomes:
from .spam import eggs
and this import:
import spam
becomes:
from . import spam
}}}
