-# About "-python_targets_python2_7":
-# The ipython stack is in a tricky transition to py3-only. It has many circular
-# dependencies which causes a chicken-and-egg problem because for Portage to
-# properly handle dependency resolution on a system with
-# python_targets_python2_7 all members of the circular dependency must go
-# py3-only at the same time. If they don't, the dependency that requires py2
-# will seek older ipython releases for resolution. This is why, for members
-# of the circular dependency, we force -python_targets_python2_7. This way, the
-# circle stays firmly in py3-only land. This only affects members of the
-# circular dependency. Other dependencies can be on py2 without problem.
-#
-# This situation also require us to explicitly depend on transitive dependencies
-# that are part of the circular dependecy so that we preserve "circle
-# integrity". It's a bit ugly, but temporary.
