+
+ Ruby was originally developed primarily by Milo Martin and Daniel
+ Sorin with contributions from Ross Dickson, Carl Mauer, and Manoj
+ Plakal.
+
+ 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,
+ Carl Mauer, Kevin Moore, Manoj Plakal, Daniel Sorin, Min Xu, and
