On a different note, a friend and I ran an analysis on the old Unix code
mentioned in the "The Power Behind the SCO Nuisance" /. article. [0] 

We did a fairly straightforward analysis of comments between Linux
2.4.20 and the source of the various ancient unixen (v5, v6, v7, sys3,
mini, 32v).  We also ran an abbreviated version of the same analysis
(abbreviated because we didn't bother to track down which specific files
contained overlapping comments) of FreeBSD 4.8's kernel and Linux

The writeup, with code and data is online. [1]
