-- | The description of the MathSAT SMT solver
-- The default executable is @\"mathsat\"@, which must be in your path. You can use the @SBV_MATHSAT@ environment variable to point to the executable on your system.
-- You can use the @SBV_MATHSAT_OPTIONS@ environment variable to override the options.
