  *
  * $Log: ec-test.c,v $
+ * Revision 1.5  2004/04/02 01:03:49  mdw
+ * Miscellaneous constification.
+ *
+ * Revision 1.4  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 1.3  2004/03/27 17:54:11  mdw
  * Standard curves and curve checking.
