+      DRAT-trim is a satisfiability proof checking and trimming
+      utility designed to validate proofs for all known satisfiability
+      solving and preprocessing techniques.  DRAT-trim can also emit
+      trimmed formulas, optimized proofs, and TraceCheck+ dependency
+      graphs.
+
+      DRAT-trim has been used as part of the judging process in the
+      annual SAT Competition in recent years, in order to check
+      competing SAT solvers' work when they claim that a SAT instance
+      is unsatisfiable.
