The equality check is used within a simplification rule that turns biconditionals into simple implications in special cases. This adds some unit tests that cover this simplification rule as well as the equality check implementation.
anthem 
Translate answer set programs to first-order theorem prover language
Overview
anthem translates ASP programs (in the input language of clingo) to the language of first-order theorem provers such as Prover9.
Usage
$ anthem [--complete] [--simplify] file...
--complete instructs anthem to perform Clark’s completion on the translated formulas.
With the option --simplify, the output formulas are simplified by applying several basic transformation rules.
