  Synopsis     [Conversion between ASCII and binary formats]

  Description  [Conversion between ASCII and binary formats is presently 
    supported by loading a BDD in the source format and storing it 
    in the target one. We plan to introduce ad hoc procedures
    avoiding explicit BDD node generation.
