+ * Revision 1.5 2000/07/15 10:00:58 mdw
+ * New generic hash operation for copying hash contexts.
+ *
+ * Revision 1.4 2000/07/03 18:08:24 mdw
+ * Include `bits.h'.
+ *
+ * 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.
