+A saturating theorem prover for full first-order logic with equality. It accepts
+a problem specification, typically consisting of a number of first-order clauses
+or formulas, and a conjecture, again either in clausal or full first-order
+form. The system will then try to find a formal proof for the conjecture,
+assuming the axioms.
