SLICC was originally developed by Milo Martin with substantial
contributions from Daniel Sorin.
Opal was originally developed by Carl Mauer based upon code by
Craig Zilles.
Substantial further development of Multifacet GEMS at the
University of Wisconsin was performed by Alaa Alameldeen, Brad
Beckmann, Ross Dickson, Pacia Harper, Milo Martin, Michael Marty,
