+// A Library is a collection of Obj_Modules that define a single shared 
+// library. It is used to manipulate the list of unresolved references by 
+// removing those that are resolved and adding those brought in by new modules
+// that are required to resolve references.  The Library is responsible 
+// for outputting a specialized makefile build the reduce footprint library.
