+## Revision 1.75 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.)
