   *) Include some named elliptic curves, and add OIDs from X9.62,
-     SECG, and WAP/WTLS.  The curves can be obtained from the new
+     SECG, and WAP/WTLS.  Each curve can be obtained from the new
      function
-          EC_GROUP_new_by_nid()
+          EC_GROUP_new_by_nid(),
+     and the list of available named curves can be obtained with
+          EC_get_builtin_curves().
      Also add a 'curve_name' member to EC_GROUP objects, which can be
      accessed via
          EC_GROUP_set_nid()
