+ * 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

+ * form.
