+Abstract:
+
+    Rewriter for "blasting" bit-vectors of size n into bit-vectors of size 1.
+    This rewriter only supports concat and extract operators.
+    This transformation is useful for handling benchmarks that contain
+    many BV equalities. 
+
+    Remark: other operators can be mapped into concat/extract by using
+    the simplifiers.
