+ * Revision 1.7  2004/04/01 12:50:09  mdw
+ * Add cyclic group abstraction, with test code.  Separate off exponentation
+ * functions for better static linking.  Fix a buttload of bugs on the way.
+ * Generally ensure that negative exponents do inversion correctly.  Add
+ * table of standard prime-field subgroups.  (Binary field subgroups are
+ * currently unimplemented but easy to add if anyone ever finds a good one.)

  * Revision 1.5  2001/06/16 13:00:04  mdw
  * Moved @mpmont_factor@ to <mp.h>.  Documented interface change to
