+ * Revision 1.3  2000/07/02 18:27:42  mdw
+ * (ghash->ops->done): Interface change.  Passing in a null buffer pointer
+ * uses a buffer internal to the ghash object.  The operation returns the
+ * address of the buffer it used.  Clients of generic hashes no longer need
+ * to use dynamically allocated memory for hash results.

  * Revision 1.2  2000/06/17 11:22:17  mdw
  * Minor changes in the generic hash interface.
