  /// If \a no_wdba or \a no_simulation is true, the corresponding

  /// that enters the accepting SCC, not just in the SCC itself.  If
  /// \a no_susp_product is true, then the composition is not
  /// performed and the skeleton automaton is returned for debugging.
  /// If \a wdba_smaller is true, then the WDBA-minimization of the
  /// skeleton is used only if it produces a smaller automaton.
  ///
  /// Finally the \a oblig flag is a work in progress and should not
  /// be set to true.

  /// This interface is subject to change, and clients aiming for
  /// long-term stability should better use the services of the
