  /// This interface let to use a Promela model as a Büchi automata.
  /// It uses the NIPS library, which provied a virtual machine for
  /// the state-space exploration of a Promela model, therefore, models
  /// must be compiled with the NIPS compiler
  /// (http://wwwhome.cs.utwente.nl/~michaelw/nips/).
  ///
  /// With this interface, properties to check aren't defined with the Spot LTL
  /// representation, but in defining correctness claims (a monitor) in the
  /// Promela model (see chapter 4, The Spin Model Checker: Primer and
  /// reference manual, Gerard J.Holzmann).
