Totally forgot to include the actual intendation script.
There should be a Python script attached to this mail. Please note,
that the script is not a silver bullet! It was designed to clean up
some pretty messed up C code. Usually I study the coding style before
creating this kind of clean-up-scripts. Also, the code is not very
clean itself (pretty ironic, I guess) :) It's just a hack to take care
of one step of the cleaning process.
