+Generate type A pairing parameters and store them in 'p',
+where the group order r is 'rbits' long, and the order of the base field q
+is 'qbits' long. Elements take 'qbits' to represent.
+
+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^2, e.g. 'rbits' = 160, 'qbits' = 512.
+
+The file `param/a.param` contains parameters for a type A pairing suitable for
+cryptographic use.
