 MARCO: an efficient MUS and MSS/MCS enumeration tool
 
-This is a Python implementation of the MARCO algorithm [1] for enumerating
-MUSes and MSS/MCSes of infeasible constraint systems (currently: CNF, GCNF, and
-SMT).  This implementation makes use of MUSer2 [2] for MUS extraction and
-MiniSAT 2.2 [3] for satisfiability testing and the generation of SAT models.
