+// Obj_Module encapsulates the result of applying nm to a single object module
+// in a shared library.  Currently an object module consists of two types of
+// signatures, those that are exported, able to resolve references from others,
+// and those that are imported, needing resolution.
+//
+// Obj_Modules keep track of external references. In the end, any module that
+// has one or more external references to it must be included in the resulting
+// library. While the means exists to remove external references, perhaps
+// through further analysis of undefined signatures and their usage, this is
+// not currently done. Once a technique is discovered to allow for easy
+// determination that reference is truly unneeded this code may be useful.
