This came up on #plan9: There's a set of programs, sig and comp, for detecting similarities between files, attributed to Rob Pike. I've found some "updated" versions, but I don't really like the updates as described and the are no notes of what the code changes were. I'd love to see the originals (with an eye towards porting them to Plan 9). 'd love to see the originals. Anyone know where (if?) they can be found?
