        GNU E is a persistent, object oriented programming language
        developed as part of the Exodus project.  GNU E extends C++
        with the notion of persistent data, program level data objects
        that can be transparently used across multiple executions of a
        program, or multiple programs, without explicit input and
        output operations.
     
        GNU E's form of {persistence} is based on extensions to the
        C++ type system to distinguish potentially persistent data
        objects from objects that are always memory resident.  An
        object is made persistent either by its declaration (via a new
        "persistent" storage class qualifier) or by its method of
        allocation (via persistent dynamic allocation using a special
        overloading of the new operator).  The underlying object
        storage system is the Exodus storage manager, which provides
        concurrency control and recovery in addition to storage for
        persistent data.
