commit fc59dd90f03cf88f4cf16c07204809f2239284ee
Author: Riccardo Magliocchetti <riccardo.magliocchetti@gmail.com>
Date:   Thu Dec 20 00:02:53 2012 +0100

    Add support for python3
    
    Libreoffice 4.0 will switch its internal python version to 3.3.0
    so it's to support that.
    
    Porting done automatically 2to3 plus print_function import added
    manually. Tested on both libreoffice master with internal python
    and with libreoffince 3.6.4 on debian with system python 2.7.
    
    This bumps the minimal python version to 2.6 since 2.5 does not
    have the print function.
