pin tar + oregano!!? that old dude be cookin' up some mighty strange brew
pin Unfortunately hits a 404 on the link.
The oregano is reputedly referring to an incident in which one of the original folks involved with BSD was hassled for coming across the Canadian/U.S. border with a bag of what was assumed to be an illegal substance, and turned out to be oregano.
I think oregano is also an old circuit simulation software
Ya know, "awk", "root", "troff" and "diff" do kinda have weird alchemy vibes to their names. Gotta admit.
