    9: NetBSD/sparc is based on work done at Lawrence Berkeley
   10: Laboratory by the Computer Systems Engineering group under DARPA
   11: contract BG 91-66, which later appeared in the 4.4BSD-Lite
   12: distribution from the University of California, Berkeley.  It was
   13: imported into the NetBSD source tree on October 2, 1993.  Special
   14: thanks are extended to the LBL Computer Systems Engineering group
   15: for their work.  Without which, this port would not exist.
