   36
   37This module provides an interface that is   similar  to the Ciao package
   38interface. Bundles are Prolog files that   are included. Typically, they
   39contain multiple use_module/1 calls.
   40
   41At least for now, the system  has   been  named  bundle because the name
   42package is already used as a package of software.
