Via harnessing Boolean satisfiability (SAT) and maximum satisfiability (MaxSAT) solvers, Pakota implements algorithms for extension and status enforcement under various central AF semantics, covering a range of NP-complete---via direct MaxSAT encodings---and $\SigmaP{2}$-complete---via MaxSAT-based counterexample-guided abstraction refinement---enforcement problems. We overview the algorithmic approaches implemented in Pakota, and describe in detail the system architecture, features, interfaces, and usage of the system. Furthermore, we present an empirical evaluation on the impact of the choice of MaxSAT solvers on the scalability of the system, and also provide benchmark generators for extension and status enforcement.
