It is rather hard, because Python 2.5 doesn't support some syntax changes
which were made in Python 3.

'except exception, variable:' => 'except exception as variable:'
https://svn.collab.net/viewvc/svn?view=revision&revision=35001

0123 => 0o123 or 0O123
https://svn.collab.net/viewvc/svn?view=revision&revision=35608

"bytes" => b"bytes"
http://docs.python.org/3.0/library/functions.html#bytes

Python 2.6 supports them.
