Python 3
========
python 3.3 will be released in August 2012, Debian freezes in June 2012. There should be a rc by this point, but it would require a freeze exception for the final release... (Judging from 3.2, no regressions are expeceted between RC and final)

* PEP 394:
 - /usr/bin/python2 -> python2.X symlink?
   We're generaly ok with it, but would like to see the PEP accepted.
   We *don't* want to see Debian actually using it.
 - /usr/bin/python -> /usr/bin/python3 symlink ?
   No!
