I played a bit with various automatic provers in the beta
alt-ergo (2.3.0), native:alt-ergo (2.3.0), cvc4 (1.6), cvc3 (2.4.1), z3 (4.8.6) are recognized. Eprover (2.4), on the other hand, is not recognized.
To be honest, Eprover is not such a great prover, but it has helped us discovering inconsistencies in our specifications. Is there a specific reason, Eprover is not supported?
Attached is the error message.
