# 2011-05-30: celeron55: simultaneous support for sectors/sectors2, removed
# 2011-06-02: j0gge: command line parameters, coordinates, players, ...
# 2011-06-04: celeron55: added #!/usr/bin/python2 and converted \r\n to \n
#                        to make it easily executable on Linux
# 2011-07-30: WF: Support for content types extension, refactoring
# 2011-07-30: erlehmann: PEP 8 compliance.

# Requires Python Imaging Library: http://www.pythonware.com/products/pil/

# Some speed-up: ...lol, actually it slows it down.
