-- | The description of the Boolector SMT solver
-- The default executable is @\"boolector\"@, which must be in your path. You can use the @SBV_BOOLECTOR@ environment variable to point to the executable on your system.
-- The default options are @\"-m --smt2\"@. You can use the @SBV_BOOLECTOR_OPTIONS@ environment variable to override the options.
