1This archive is derived from the original SCCS repository maintained by 2the Computer Systems Research group. The project began using a source 3code control system (SCCS) in 1980 (three years after Bill Joy began his 4initial Berkeley UNIX development). Initially only the kernel was put 5under SCCS, but by 1983 everything had been put under SCCS. 6 7This work is distributed under the following terms: 8 9Copyright 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 10 The Regents of the University of California.
