/*----- Revision history --------------------------------------------------*

* $Log: ectab.h,v $
+ * Revision 1.3 2004/04/01 21:28:41 mdw
+ * Normal basis support (translates to poly basis internally). Rewrite
+ * EC and prime group table generators in awk, so that they can reuse data
+ * for repeated constants.
+ *
* Revision 1.2 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.
