-    Put clauses in the assertion set in

-    Constraints occurring in formulas that

+### Short Description
+
+Put goal in one constraint per clause normal form 
+
+### Long Description
+
+Put clauses in the assertion set in
+OOC (one constraint per clause) form.
+Constraints occurring in formulas that
+are not clauses are ignored.
+The formula can be put into CNF by
+using `mk_sat_preprocessor` strategy.
+
+### Example
+
+```z3
+(declare-const x Int)
+(declare-const y Int)
+
+(assert (or (= x y) (> x (- y))))
+(assert (or (= x y) (< x (- y))))
+(apply occf)
+```
+
+### Notes
+
+* Does not support proofs
+* only clauses are considered
