From 5e0ee145759b4a197bea347ad77e1ad1609efd32 Mon Sep 17 00:00:00 2001 From: Conley Owens Date: Thu, 26 Sep 2013 15:50:49 -0700 Subject: [PATCH] Do not use print_function from __future__ Python 2.4 and 2.5 do not have a print_function available, so we need a compatible print function for displaying an error message when the user has an older version of Python.
