+* Additional features contributed by Anthony Romano <chz@vt.edu>.
+
+* The original structure and form of this operating system is inspired
+  by the Nachos system from the University of California, Berkeley.  A
+  few of the source files are more-or-less literal translations of the
+  Nachos C++ code into C.  These files bear the original UCB license
+  notice.

+projects
+--------
+
+* The projects are primarily the creation of Ben Pfaff
+  <blp@cs.stanford.edu>.
+
+* Godmar Back <godmar@gmail.com> made significant contributions to
+  project design.
+
+* Although little remains unchanged, the projects were originally
+  derived from those designed for Nachos by current and former CS140
+  teaching assistants at Stanford University, including at least the
+  following people:
+	
+	- Yu Ping <yph@cs.stanford.edu>
+
+	- Greg Hutchins
+
+	- Kelly Shaw <kashaw (at) cs.stanford.edu>, 
+
+	- Paul Twohey <twohey AT cs DOT stanford DOT edu>
+
+	- Sameer Qureshi <squreshi@cs.stanford.edu>
+
+	- John Rector

+* Example code for condition variables is from classroom slides
+  originally by Dawson Engler and updated by Mendel Roseblum.
