+    <p>
+        To create a scalable parser to read scene files according to
+        a grammar that I supplied, I used the bison parser generator.
+        I used bison because it is very portable and worked directly
+        with my C++ code.
+        The parser produces a hierarchy of <tt>Node</tt> objects.
+        Each <tt>Node</tt> object represents some part of the parse tree
+        obtained from the scene description file.
+        Thus, the parse tree can be traversed after parsing is complete
+        in order to evaluate all of the scene objects specified in the
+        scene file, maintaining node order and parent/child relationships.
