# Whats this?

# I tried to write a piece of code that executes my changes in a file automatically.

# Worked great with Python 2.7.

# BUT it did not work with Python 2.6

# I Wrote it under Ubuntu 12.04 but have Debian 6 on my Laptop.

# FOOOOO!!1!

# So I used "clear; python cc.py" for my Presentation instead -.-
