+Type G curves are generated using the complex multiplication (CM) method.  This
+function sets 'p' to a type G pairing parameters from CM parameters 'cm'.
+They have embedding degree 10.
+
+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^6^.  For usual CM parameters, r is a few bits smaller than q.
+
+They are quite slow at the moment so for now type F is a better choice.
+
+The file `param/g149.param` contains parameters for a
+type G pairing with 149-bit group and field sizes.
