+// This file defines the abstract ValueNumbering interface, which is used as the
+// common interface used by all clients of value numbering information, and
+// implemented by all value numbering implementations.
+//
+// Implementations of this interface must implement the various virtual methods,
+// which automatically provides functionality for the entire suite of client
+// APIs.
