1.1       deraadt    48: OpenBSD looks a lot like NetBSD (which it is derived from, following
                     49: the 4.4BSD roots), but is now being developed seperately.  Good changes
                     50: from other free operating systems will be merged in (of course, depending
1.24      deraadt    51: on various factors like developer time for example.)  OpenBSD tracks
                     52: NetBSD changes very closely; say anywhere between 2 days to 10 days
                     53: behind the state of NetBSD-current all the time.  Hence you can truly
                     54: say that OpenBSD is NetBSD <b>PLUS MORE STUFF</b>.
