+
+# Data Structures
+
+The compiled code is stored in a list that contains:
+
+- A string that contains the actual generated code.
+- A list of strings that represent all of the local C variables that are necessary to support the generated code
+
+For example:
+
+    cyclone> (c-compile-prim '+ "")
+    ("c_732" ("object c_732 = Cyc_sum(data,"))
+
+# Compiled Code

+TODO: explain each type of code:

+    ((ref?   exp)       (c-compile-ref exp))
