+Generate type F pairing parameters and store them in 'p'.
+Both the group order r and the order of the base field q will be roughly
+'bits'-bit numbers.
+To be secure, generic discrete log algorithms must
+be infeasible in groups of order r, and finite field discrete log algorithms
+must be infeasible in finite fields of order q^12, e.g. 'bits' = 160.
+
+Type F should be used when the top priority is to minimize bandwidth (e.g.
+short signatures). The current implementation makes them slow.
+
+If finite field discrete log algorithms improve further, type D pairings will
+have to use larger fields, but type F can still remain short, up to a point.
