- * Revision 1.4  2004/03/22 02:19:10  mdw
- * Rationalise the sliding-window threshold.  Drop guarantee that right

- * to cope.
- *
- * Revision 1.3  2004/03/21 22:52:06  mdw
- * Merge and close elliptic curve branch.

- * Revision 1.2.4.1  2004/03/20 00:13:31  mdw
- * Projective coordinates for prime curves
- *
- * Revision 1.2  2003/05/15 23:25:59  mdw
- * Make elliptic curve stuff build.
