  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.
