+George Wood and Jim Kowalski. CMU Common Lisp modifications by

+Dario Guise, Skef Wholey, Michael Parzen, and Dan Kuokka. 

+Modified to work in CLtL1, CLtL2 and X3J13 compatible lisps by 

+Mark Kantrowitz on 14-OCT-92. The auto.ops and reactor.ops demo files

+were provided by Michael Mauldin. In year 2013, ported to modern Common

+Lisp implementations and added support for quicklisp by Xiaofeng Yang.
