In particular, I looked into benchmark and the shootout….

I found an archive in the wayback machine, which may provide some data to update LEGAL with a bit more data: 

According to this (https://web.archive.org/web/20010418111739/http://www.bagley.org/~doug/shootout/ack.shtml) it seems the venerable Dave Thomas contributed to a bunch of the ruby versions :)

Another/followup version is here:

And then there are a few examples where MIT or other known licenses are in use for files, with just the copyright changing. Is it valuable to reproduce them over and over in LEGAL? Or would perhaps a yaml/json/something manifest outlining each file, copyright and license be potentially more useful? 

I know it’s not really high priority, but figured it might be worth making it a little more accurate as Jeremy’s point stands- it does currently assert that anything not identified properly in that file belongs to Matz, which is a bit ¯\_(ツ)_/  — not great, not evil, just not perfect. 🙂
