+DESCRIPTION:
+
+        This grammar supports the Standard C language.
+
+        Note clearly that this grammar does *NOT* deal with
+        preprocessor functionality (including things like trigraphs)
+        Nor does this grammar deal with multi-byte characters nor strings
+        containing multi-byte characters [these constructs are "exercises
+        for the reader" as it were :-)].

+  (this is currently incomplete, in that method doubleLink() must
+  be called after any changes to the tree to maintain the 
+  reverse links).
+
+  It can store a definition node (defNode), so that nodes such
+  as scoped names can refer to the node that defines the name.
+
+  It stores line numbers for nodes.
+
+  Searches for parents and children of a tree can be done
+  based on their type.
+
+  The tree can be printed to System.out using a lisp-style syntax.
