 DSA_new_method() allocates and initializes a DSA structure so that B<engine>

 for DSA operations is used, and if no default ENGINE is set, the DSA_METHOD
 controlled by DSA_set_default_method() is used.

-
-As of version 0.9.7, DSA_METHOD implementations are grouped together with other
-algorithmic APIs (eg. RSA_METHOD, EVP_CIPHER, etc) in B<ENGINE> modules. If a
-default ENGINE is specified for DSA functionality using an ENGINE API function,
-that will override any DSA defaults set using the DSA API (ie.

-=head1 HISTORY
+=head1 COPYRIGHT
 
-DSA_set_default_method(), DSA_get_default_method(), DSA_set_method(),
-DSA_new_method() and DSA_OpenSSL() were added in OpenSSL 0.9.4.
+Copyright 2000-2016 The OpenSSL Project Authors. All Rights Reserved.
 
-DSA_set_default_openssl_method() and DSA_get_default_openssl_method() replaced
-DSA_set_default_method() and DSA_get_default_method() respectively, and
-DSA_set_method() and DSA_new_method() were altered to use B<ENGINE>s rather than
-B<DSA_METHOD>s during development of the engine version of OpenSSL 0.9.6. For
-0.9.7, the handling of defaults in the ENGINE API was restructured so that this
-change was reversed, and behaviour of the other functions resembled more closely
-the previous behaviour. The behaviour of defaults in the ENGINE API now
-transparently overrides the behaviour of defaults in the DSA API without
-requiring changing these function prototypes.
