    Description: provides a module to determine whether object files
                 are already known.  An object file will be known by
                 its name and ultimately its inode.

   RegisterModuleObject - returns TRUE if location has not already been registered.

PROCEDURE RegisterModuleObject (fo: FileObjects; location: String) : BOOLEAN ;


(*
   IsRegistered - returns TRUE if the object at, location, is already registered.
                  It uses the physical location on the filesystem to determine the
                  uniqueness of the object file.
