% Changes in the SCO Unix(r) license % David Parsons % Tue Jan 15 23:40:40 PST 2008 #Changes in the SCO Unix(r) license In January 2002, [Caldera](http://www.caldera.com) (which merged with the [Santa Cruz Operation](http://www.sco.com) during the Linux bubble) re-released many ancient versions of UNIX(r) under a [BSD-style license](/~orc/Caldera-License.html). This new license means that you may use the ancient versions of UNIX(r) here for any purpose, commercial or not, as long as you properly credit them for their generosity.
