+Module Name:
+
+    NodeType.h
+
+Abstract:
+
+    This module defines all of the node type codes used in this development
+    shell.  Every major data structure in the file system is assigned a node
+    type code that is.  This code is the first CSHORT in the structure and is
+    followed by a CSHORT containing the size, in bytes, of the structure.
