I must be missing something, but I don't see how the actual text of the paper originates from the source code. Those C instructions actually compile into the sentences of the paper as well?
From what I can tell, the .exe file generated by the compiler must be really big anyway (since the relevant sizes in the header can't be small because they have to be printable). So there must be some text, it might as well be the paper.
