 # Porting to Python 3
 
-This is still a proposal at this stage.

 ## Motivation
 
 * Make code behave the same on Python 2 and Python 3, insofar as one can, so e.g. `map()` is the same on Python 2 and Python 3 (i.e. lazy).

 TBD, something involving core abstractions first, then dependency graph topological traversal.
 
-Assume for now we've picked a module.
+At the moment we're focusing on just porting `allmydata.util`, since it's necessary for other packages.
 
 ## The porting process, big picture

+If you just want to run the tests from the explicitly ported test modules, you can do `python -m allmydata.util._python3`.
