+Nam is a Tcl/TK based animation tool for viewing network simulation traces 
+and real world packet traces. It supports topology layout, packet level 
+animation, and various data inspection tools. 
+
+Nam began at LBL. It has evolved substantially over the past few years. 
+The nam development effort is now an ongoing collaboration with 
+the VINT project.
