  * The curves we consider are defined by y^2 = x^3 + A x + B mod P,
  * and a generator for a large subgroup of order N is fixed.
  *
- * If A is not set (ie A.p == NULL) then the value A = -3 is assumed,
- * which allows the used of slightly faster point doubling formulas.
- *
  * pbits and nbits must be the size of P and N in bits.
  *
  * If modp is NULL, reduction modulo P is done using a generic algorithm.
