I am not sure it is useful (and realistic) to have all our Python
scripts compatible with Python 2.6. This puts a pretty hard constraint
which might be annoying down the road. So Python scripts involved in
the build itself should definitely be compatible with Python 2.6, but
all the utility Python scripts around that are not essential for the
build, I don't think we should enforce this constraint.

Best regards,

Thomas
