# compatibility3.py # # Backwards compatibility for text mode Python 1.4.0 to 3.2.2... # Some simple lines that work for all these versions on the # classic AMIGA, E-UAE, PCLinuxOS 2009, Debian 6.0.0, Windows XP and # Vista and WinUAE. Note, classic AMIGAs and derivatives only reach # Python version 2.4.6.
