-// 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.
