copycenter n.
[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".
