10K lines is not _that_ large. If it was written sensibly, it might be very useful. Bill might have written a text document, but chose to use Shell as a preferred engineers' language. Who doesn't share a one-liner with a colleague in need? Bill shared a 10k-liner :-). And Shell being a relatively high-level language, it probably packs the information more densely than a text file.
