  // \brief Load a DVE model.
  //
  // The filename given can be either a *.dve source or a *.dve2C
  // dynamic library compiled with "divine compile --ltsmin file".
  // When the *.dve source is supplied, the *.dve2C will be updated
  // only if it is not newer.
  //
  // The dead parameter is used to control the behavior of the model
  // on dead states (i.e. the final states of finite sequences).
  // If DEAD is "false", it means we are not
  // interested in finite sequences of the system, and dead state
  // will have no successor.  If DEAD is
  // "true", we want to check finite sequences as well as infinite
  // sequences, but do not need to distinguish them.  In that case
  // dead state will have a loop labeled by true.  If DEAD is any
  // other string, this is the name a property that should be true
  // when looping on a dead state, and false otherwise.
  //
  // This function returns 0 on error.
  //
