Make it very clear that some of the functions here are derived from

CL-JSON, but all of these are extensively modified.

+;;; This file modifies the basic behavior of CL-JSON.  All of the
+;;; functions that directly modify and manipulate how cl-json reads
+;;; input are derived from the way CL-JSON does the default handling.
+;;;
+;;; My modifications are pretty extensive, but for completeness:
+;;;
+;;; Specifically
+;;; -  beginning-of-object 
+;;; -  key-add-or-set 
+;;; -  value-add-or-set
+;;; -  accumulator-get-object 
+;;; -  accumulator-add-preserved-key
+;;; Are especially derived from CL-JSON.
+;;;
+;;; CL-JSON's license is included here for completeness.
