+Strength-based decomposition of the property Büchi automaton for faster
+model checking. Proceedings of TACAS'13. LNCS 7795.

+The \fB\-\-strength\-decompose\fR option implements the definitions
+given in the above paper.

+On refinement of Büchi automata for explicit model checking.
+Proceedings of SPIN'15.  LNCS 9232.
+
+That paper gives the motivation for options \fB\-\-exclusive\-ap\fR
+and \fB\-\-simplify\-exclusive\-ap\fR.

+Describes the algorithms used by the \fB\-\-destut\fR and
+\fB\-\-instut\fR options.  These options correpond respectively to
+cl() and sl() in the paper.
