Looks good to me, Dirk.

One question: what does this mean, exactly?

As of Raring Ubuntu will ship with Python 3 by default. While we still support Ubuntu versions 
which ship with Python 2 by default all Python scripts should provide dual compatibility with 
Python 2.7+ and Python 3.3+.

Since Raring is supported for Hydro, will all scripts provide dual 2.7 and 3.3 compatibility at that time? Is that even possible?

[dirk-thomas]

Yes exactly that is necessary. Since we need to use the default Python versions on Precise and Raring all scripts must work with both Python version.

[jack-oquin]

That is one solution, but perhaps not the only one.

This needs a much wider discussion within the ROS community.

[dirk-thomas]

Then please post alternate solutions on the mailing list and we can figure out which one is best suited for the REP.

[jack-oquin]

OK. Which mailing list do you suggest, ros-users?

The question seems much more general than ros-sig-buildsystem.

[tfoote]

ros-users is probably right.

I've ticketed to discus the python element in ros/rosdistro#506 We'll use the proposal as the working default pending a different outcome from the discussion.
