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'".
