A Brief history of sudo(8):
Sudo was first conceived and implemented by Bob Coggeshall and Cliff
Spencer around 1980 at the Department of Computer Science at
SUNY/Buffalo. It ran on a VAX-11/750 running 4.1BSD. An updated
version, credited to Phil Betchel, Cliff Spencer, Gretchen Phillips,
John LoVerso and Don Gworek, was posted to the net.sources newsgroup
in December of 1985.
