[play on `copyright' and `copyleft'] 1. The
copyright notice carried by the various flavors of freeware BSD.
According to Kirk McKusick at BSDCon 1999: "The way it was
characterized politically, you had copyright, which is what the big
companies use to lock everything up; you had copyleft, which is
free software's way of making sure they can't lock it up; and then
Berkeley had what we called "copycenter", which is "take it down
to the copy center and make as many copies as you want".
